Subject: [PATCH 0003/1375] ath10k: set peer MFP flag in peer assoc command

Set peer's management frame protection flag in peer assoc command,
this setting will enable/disable encrytion of management frames in fw.

Setting of this flag is based on whether MFP is enabled/disabled at STA
and a firmware feature flag ATH10K_FW_FEATURE_MFP_SUPPORT. This is because
only firmwares 10.1.561 and above have support for MFP.

Subject: [PATCH 0009/1375] ath10k: debugfs file to enable Bluetooth
 coexistence feature

As not all QCA98XX radios are not connected to Bluetooth modules, enabling the
BT coex feature in firmware will have side effects if the radio's GPIO are
connected with other (non-BT) HW modules. Add debugfs file to control the
firmware BT coex logic and set the feature as disable by default to avoid that
btcoex is accidentally enabled.

To enable this feature, execute:

echo 1 > /sys/kernel/debug/ieee80211/phyX/ath10k/btcoex

To disable:

echo 0 > /sys/kernel/debug/ieee80211/phyX/ath10k/btcoex

The firmware support this feature since 10.2.4.54 on 2G-only board, dual band
or 5G boards don't support this. The feature's name is WMI_SERVICE_COEX_GPIO
and the btcoex file is not created if firmware doesn't support it.

Subject: [PATCH 0010/1375] ath10k: fix peer assoc complete WMI command for
 10.4

There is an extra 4-byte member when compared to WMI 10.2 added to
assoc complete command in WMI 10.4. This new member is used for 160Mhz
related configuration. This WMI command mismatch between host and
firmware does not cause any real issues because this new member is not
used in 10.4 firmwares so far (10.4.1.00030-1). This difference in WMI
command interface brings in a new wmi_ops for 10.4 gen_peer_assoc().
No noticeable functionality differences with this change can be seen
with the current 10.4 firmwares, but the WMI interface has to be
fixed to work with future 10.4 firmwares which may be using this new
member.

Subject: [PATCH 0012/1375] ath10k: fix peerid configuration in htt tx desc for
 htt version < 3.4

Of a word in struct htt_data_tx_desc htt version >= 3.4 firmware uses
LSB 16-bit for frequency configuration which is used for offchannel tx
and MSB 16-bit is for peerid. But other firmwares using version 2.X
(10.1, 10.2.2, 10.2.4 and 10.4) are using 32-bit for peerid in htt tx
desc. So far no issue is found with the existing code setting peerid and
freq for HTT version 2.X, this could be mainly because of 0 as frequecy
(home channel) is being always passed with those firmwares. There may be
issues when non-zero freq is passed with firmware using < 3.4 htt version.
To be safe use target_version_major and target_version_minor along with
htt-op-version before configuring peer id and freq in htt tx desc. This
patch extends ath10k_mac_tx_frm_has_freq() to check for htt_op_version_tlv
and uses the helper while setting peerid in htt_tx_desc.

Subject: [PATCH 0013/1375] ath10k: fix the wrong RX rate idx report at 11G
 mode

The RX rate idx is not correct for 11G mode OFDM packet.
Because the bitrate table start with CCK index instead of OFDM.

Subject: [PATCH 0014/1375] wil6210: hold wil->mutex while managing vrings

To prevent race when connect flow may run in parallel with
the disconnect event.

Scenario leading to the bug is: while running connect flow on the AP,
STA sends disconnect. log follows.

Subject: [PATCH 0016/1375] nxp-nci: i2c: Do not check specifically for
 -EREMOTEIO error

Function nxp_nci_i2c_write currently assumes in case of
I2C bus NACK that the NFC device is in stand-by mode and
will retry the I2C transaction after a pause. This assumes
that the first failed I2C transaction will wake-up the device.

This is done by checking on EREMOTEIO, which is wrong. According
to Documentation/i2c/fault-codes ENXIO shall be used. Unfortunately
the NOACK return code is currently inconsistent across various I2C
host controller drivers. So only check for the generic error case
instead.

This is a temporary fix. As soon as all I2C bus master drivers are
fixed to consistently return 'ENXIO', then we can do the specific
error check again.

Subject: [PATCH 0040/1375] ti: unify Kconfig with other vendors

Rename WL_TI to WLAN_VENDOR_TI to match with other vendor configs and make sure
that it's enabled by default in new configs. Convert menuconfigs to regular
configs to unify the wireless drivers menuconfig. Part of reorganising wireless
drivers directory and Kconfig.

Also remove WLCORE dependency to WL_TI. It should not be needed as WLCORE is
already under if  WLAN_VENDOR_TI.

Subject: [PATCH 0045/1375] be2net: remove local variable 'status'

The lancer_cmd_get_file_len() uses lancer_cmd_read_object() to get
the current size of registers for ethtool registers dump. Returned status
value is stored but not checked. The check itself is not necessary as
the data_read output variable is initialized to 0 and status variable
can be removed.

Subject: [PATCH 0046/1375] net: better skb->sender_cpu and skb->napi_id
 cohabitation

skb->sender_cpu and skb->napi_id share a common storage,
and we had various bugs about this.

We had to call skb_sender_cpu_clear() in some places to
not leave a prior skb->napi_id and fool netdev_pick_tx()

As suggested by Alexei, we could split the space so that
these errors can not happen.

0 value being reserved as the common (not initialized) value,
let's reserve [1 .. NR_CPUS] range for valid sender_cpu,
and [NR_CPUS+1 .. ~0U] for valid napi_id.

This will allow proper busy polling support over tunnels.

We'll soon make it even bigger in following patches.

Subject: [PATCH 0049/1375] net: allow BH servicing in sk_busy_loop()

Instead of blocking BH in whole sk_busy_loop(), block them
only around ->ndo_busy_poll() calls.

This has many benefits.

1) allow tunneled traffic to use busy poll as well as native traffic.
   Tunnels handlers usually call netif_rx() and depend on net_rx_action()
   being run (from sofirq handler)

2) allow RFS/RPS being used (sending IPI to other cpus if needed)

3) use the 'lets burn cpu cycles' budget to do useful work
   (like TX completions, timers, RCU callbacks...)

4) reduce BH latencies, making busy poll a better citizen.

Tested:

Tested with SIT tunnel

Subject: [PATCH 0050/1375] net: network drivers no longer need to implement
 ndo_busy_poll()

Instead of having to implement complex ndo_busy_poll() method,
drivers can simply rely on NAPI poll logic.

Busy polling gains are mainly coming from polling itself,
not on exact details on how we poll the device.

ndo_busy_poll() if implemented can avoid touching
napi state, but it adds extra synchronization between
normal napi->poll() and busy poll handler, slowing down
the common path (non busy polling) with extra atomic operations.
In practice few drivers ever got busy poll because of the complexity.

We could go one step further, and make busy polling
available for all NAPI drivers, but this would require
that all netif_napi_del() calls are done in process context
so that we can call synchronize_rcu().
Full audit would be required.

Before this is done, a driver still needs to call :

- skb_mark_napi_id() for each skb provided to the stack.
- napi_hash_add() and napi_hash_del() to allocate a napi_id per napi struct.
- Make sure RCU grace period is respected after napi_hash_del() before
  memory containing napi structure is freed.

Followup patch implements busy poll for mlx5 driver as an example.

Subject: [PATCH 0051/1375] mlx5: add busy polling support

It is now easy to add busy polling support to a NAPI driver,
with very little impact on normal input path.

This patch serves as a reference implementation.

Note:

A followup patch will add proper napi_complete_done() in mlx5,
so that LINUX_MIB_BUSYPOLLRXPACKETS snmp counter is properly handled.

Tested:

Normal TCP_RR results without busy polling :

lpk51:~# echo 0 >/proc/sys/net/core/busy_read
lpk52:~# echo 0 >/proc/sys/net/core/busy_read

lpk51:~# ./netperf -H 192.168.4.52 -t TCP_RR -l 10

Now enable busy polling :

lpk51:~# ./netperf -H 192.168.4.52 -t TCP_RR -l 10

Subject: [PATCH 0052/1375] mlx5: support napi_complete_done()

A NAPI poll handler should return number of RX packets processed,
instead of 0 / budget.

This allows proper busy poll accounting through LINUX_MIB_BUSYPOLLRXPACKETS
SNMP counter.

napi_complete_done() allows /sys/class/net/ethX/gro_flush_timeout
to be used for finer GRO aggregation control.

Tested:

Enabled busy polling, and checked TcpExtBusyPollRxPackets counter is increasing.

echo 70 >/proc/sys/net/core/busy_read
nstat >/dev/null
netperf -H target -t TCP_RR >/dev/null
nstat | grep TcpExtBusyPollRxPackets
TcpExtBusyPollRxPackets         490958             0.0

Subject: [PATCH 0053/1375] bnx2x: remove bnx2x_low_latency_recv() support

Switch to native NAPI polling, as this reduces overhead and complexity.

Normal path is faster, since one cmpxchg() is not anymore requested,
and busy polling with the NAPI polling has same performance.

Tested:
lpk50:~# cat /proc/sys/net/core/busy_read
70
lpk50:~# nstat >/dev/null;./netperf -H lpk55 -t TCP_RR;nstat

Subject: [PATCH 0054/1375] mlx4: remove mlx4_en_low_latency_recv()

Busy polling can now be handled in generic NAPI poll infrastructure.
This removes complexity and fast path overhead :

mlx4 used two spin_lock()/spin_unlock() pair per napi->poll() call
in mlx4_en_cq_lock_napi()/mlx4_en_cq_unlock_napi()

Tested:

Without busy polling :

lpaa23:~# echo 0 >/proc/sys/net/core/busy_read
lpaa24:~# echo 0 >/proc/sys/net/core/busy_read
lpaa23:~# ./netperf -H lpaa24 -t TCP_RR
MIGRATED TCP REQUEST/RESPONSE TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to lpaa24.prod.google.com () port 0 AF_INET : first burst 0

From 93f93a4404159ecf7e9148f5ad0718ec702ac4cb Mon Sep 17 00:00:00 2001
From: Eric Dumazet <edumazet@google.com>

Subject: [PATCH 0055/1375] net: move skb_mark_napi_id() into core networking
 stack

We would like to automatically provide busy polling support
to all NAPI drivers, without them having to implement anything.

skb_mark_napi_id() can be called from napi_gro_receive() and
napi_get_frags().

Few drivers are still calling skb_mark_napi_id() because
they use netif_receive_skb(). They should eventually call
napi_gro_receive() instead. I will leave this to drivers
maintainers.

Subject: [PATCH 0056/1375] net: add netif_tx_napi_add()

netif_tx_napi_add() is a variant of netif_napi_add()

It should be used by drivers that use a napi structure
to exclusively poll TX.

We do not want to add this kind of napi in napi_hash[] in following
patches, adding generic busy polling to all NAPI drivers.

Subject: [PATCH 0058/1375] net: napi_hash_del() returns a boolean status

napi_hash_del() will soon be used from both drivers (if they want)
or core networking stack.

Callers are responsibles to ensure an RCU grace period is respected
before freeing napi structure : napi_hash_del() can signal if
this RCU grace period is needed or not.

Subject: [PATCH 0059/1375] net: provide generic busy polling to all NAPI
 drivers

NAPI drivers no longer need to observe a particular protocol
to benefit from busy polling (CONFIG_NET_RX_BUSY_POLL=y)

napi_hash_add() and napi_hash_del() are automatically called
from core networking stack, respectively from
netif_napi_add() and netif_napi_del()

This patch depends on free_netdev() and netif_napi_del() being
called from process context, which seems to be the norm.

Drivers might still prefer to call napi_hash_del() on their
own, since they might combine all the rcu grace periods into
a single one, knowing their NAPI structures lifetime, while
core networking stack has no idea of a possible combining.

Once this patch proves to not bring serious regressions,
we will cleanup drivers to either remove napi_hash_del()
or provide appropriate rcu grace periods combining.

From 618e8bc228cda7b8c517caac40a45ee909b8672d Mon Sep 17 00:00:00 2001
From: Marcel Holtmann <marcel@holtmann.org>
Date: Thu, 5 Nov 2015 07:33:56 +0100
Subject: [PATCH 0066/1375] Bluetooth: Use new hci_skb_pkt_* wrappers for
 drivers

The new hci_skb_pkt_* wrappers are mainly intented for drivers to
require less knowledge about bt_cb(sbk) handling. So after converting
the core packet handling, convert all drivers.

 bt_cb

The socket allocation functions will always memset skb->cb to zero so
there's no need to make other initializations needing the same thing.

Subject: [PATCH 0068/1375] Bluetooth: Compress the size of struct hci_ctrl

We can reduce the size of the hci_ctrl struct by converting
'bool req_start' to 'u8 req_flags' and making the two function
pointers a union (since only one is ever set at a time).

Subject: [PATCH 0073/1375] Bluetooth: Add support for controller specific
 logging

To enable controller specific logging, the userspace daemon has to have
the ability to log per controller. To facilitate this support, provide
a dedicated logging channel. Messages in this channel will be included
in the monitor queue and with that also forwarded to monitoring tools
along with the actual hardware traces.

All messages from the logging channel are timestamped and with that
allow an easy correlation between userspace messages and hardware
events. This will increase the ability to debug problems faster.

Subject: [PATCH 0074/1375] Bluetooth: Remove unnecessary call to

The hci_conn_params_clear_all() function is only called from
hci_unregister_dev() at which point it's completely futile to try to
do any LE scanning updates. Simply remove this unnecessary function
call. At the same time we can make the function static since it's only
accessed from within the same c-file.

Subject: [PATCH 0077/1375] Bluetooth: Add stubs for synchronous HCI request
 functionality

Prepare hci_request.c to have code for doing synchronous HCI requests,
such as LE scanning or advertising changes. The necessary work
callbacks will be set up in hci_request_setup() and cleaned up in
hci_request_cancel_all(). The former is used when an HCI device get
registered, and the latter each time it is powered off (or
unregistered).

Instead of firing off a simple async request queue all background scan
updates through req_workqueue and use hci_req_sync() there to ensure
that no two updates overlap with each other.

Subject: [PATCH 0079/1375] Bluetooth: Don't wait for HCI in Add/Remove Device

There's no point in waiting for HCI activity in Add/Remove Device
since the effects of these calls are long-lasting and we can anyway
not report up to the application all HCI failures.

Subject: [PATCH 0080/1375] Bluetooth: Add HCI status return parameter to
 hci_req_sync()

In some cases it may be important to get the exact HCI status rather
than the converted HCI-to-errno value. Add an optional return
parameter to the hci_req_sync() API to allow for this. Since there are
no good HCI translation candidates for cancelation and timeout, use
the "unknown" status code for those cases.

Subject: [PATCH 0085/1375] Bluetooth: Add discovery type validity helper

As preparation for moving the discovery HCI commands behind
req_workqueue, add a helper and do the validity checks of the given
discovery type before proceeding further. This way we don't need to do
them again in hci_request.c.

Subject: [PATCH 0086/1375] Bluetooth: Add error return value to hci_req_sync
 callback

In some circumstances it may be useful to abort the request through
checks done in the request callback. To make the feature possible this
patch changes the return value of the request callback from void to
int and aborts the request if a non-zero value is returned.

Subject: [PATCH 0087/1375] Bluetooth: Move Start Discovery to req_workqueue

Since discovery also deals with LE scanning it makes sense to move it
behind the same req_workqueue as other LE scanning changes. This also
simplifies the logic since we do many of the actions in a synchronous
manner.

Subject: [PATCH 0088/1375] Bluetooth: Move Stop Discovery to req_workqueue

Since discovery also deals with LE scanning it makes sense to move it
behind the same req_workqueue as other LE scanning changes. This also
simplifies the logic since we do many of the actions in a synchronous
manner.

Part of this refactoring is moving hci_req_stop_discovery() to
hci_request.c. At the same time the function receives support for
properly handling the STOPPING state since that's the state we'll be
in when stopping through the req_workqueue.

The recent changes to remove dependency on HCI in Add Device missed
out relevant changes for BR/EDR. This patch removes the left-overs and
ensures the right HCI command gets queued for BR/EDR.

Passing the needed inquiry length to bredr_inquiry() makes it possible
to also use this helper for interleaved discovery where the controller
doesn't support simultaneous Inquiry & LE scan.

Subject: [PATCH 0093/1375] Bluetooth: Fix specifying role for LE connections

The hci_connect_le_scan() is (as the name implies) a master/central
role API, so it makes no sense in passing a role parameter to it. At
the same time this patch also fixes the direct advertising support for
LE L2CAP sockets where we now call the more appropriate hci_le_connect()
API if slave/peripheral role is desired.

Subject: [PATCH 0095/1375] Bluetooth: Remove conn_unfinished variable from

The conn_unfinished variable makes the entire logic of
hci_connect_le() rather confusing. By restructuring and clarifying the
logic we can actually remove the conn_unfinished variable and still
keep the same behavior.

Subject: [PATCH 0096/1375] Bluetooth: Simplify request cleanup code

The hci_req_sync_cancel() is just as much related to the request
cleanup as hci_request_cancel_all() is. Just move the former into the
latter and do the cleanup from a single place in hci_dev_do_close().
The important thing is to avoid deadlocks by holding the req_sync
lock: previously hci_request_cancel_all was done right after releasing
the lock and with this patch it's right before taking it.

When removing a range of VLANs in which PVID is a member we should use
the correct PVID value instead of some VLAN in the range.

Also, change two print statements to use 'dev' instead of
'mlxsw_sp_port->dev', as it's already used in other print statements in
the function.

The operation of adding VLANs on a port via switchdev ops can fail and
we need to be prepared for it. If we do not rollback hardware operations
following a failure, hardware and software will remain in an
inconsistent state.

Solve that by adding suitable error paths to __mlxsw_sp_port_vlans_add.

Subject: [PATCH 0109/1375] ppp: don't set sk_state to PPPOX_ZOMBIE in
 pppoe_disc_rcv()

Since 287f3a943fef ("pppoe: Use workqueue to die properly when a PADT
is received"), pppoe_disc_rcv() disconnects the socket by scheduling
pppoe_unbind_sock_work(). This is enough to stop socket transmission
and makes the PPPOX_ZOMBIE state uncessary.

Subject: [PATCH 0112/1375] bnx2x: Show port statistics in Multi-function

Today, port statistics are being presented when using `ethool -S' only
for single-function devices, but there are some port statistics which are
crucial for analyzing bottle-necks. E.g., HW Rx discards due to lack of
buffer space [when device isn't handling ingress traffic fast enough].

Judging the pros and cons, it was decided that in-order to better support
automatic dump-gathering tools, bnx2x should no longer hide those stats.
This leaves only VFs lacking the port statistics.

Subject: [PATCH 0113/1375] tipc: move linearization of buffers to generic code

In commit 5cbb28a4bf65c7e4 ("tipc: linearize arriving NAME_DISTR
and LINK_PROTO buffers") we added linearization of NAME_DISTRIBUTOR,
LINK_PROTOCOL/RESET and LINK_PROTOCOL/ACTIVATE to the function
tipc_udp_recv(). The location of the change was selected in order
to make the commit easily appliable to 'net' and 'stable'.

We now move this linearization to where it should be done, in the
functions tipc_named_rcv() and tipc_link_proto_rcv() respectively.

Subject: [PATCH 0114/1375] tipc: small cleanup of function
 tipc_node_check_state()

The function tipc_node_check_state() contains the core logics
for handling link synchronization and failover. For this reason,
it is important to keep it as comprehensible as possible.

In this commit, we make three small cleanups.

1) If the node is in state SELF_DOWN_PEER_LEAVING and the received
   packet confirms that the peer has lost contact, there will be no
   further action in this function. To make this clearer, we return
   from the function directly after the state change.

2) Since commit 0f8b8e28fb3241f9fd ("tipc: eliminate risk of stalled
   link synchronization") only the logically first TUNNEL_PROTO/SYNCH
   packet can alter the link state and set the synch point,
   independently of arrival order. Hence, there is not any longer any
   need to adjust the synch value in case such packets arrive in
   disorder. We remove this adjustment.

3) It is the intention that any message arriving on any of the links
   may trig a check for and possible termination of a node SYNCH state.
   A redundant and unnoticed check for tipc_link_is_synching() obviously
   beats this purpose, with the effect that only packets arriving on the
   synching link may currently end the synch state. We remove this check.
   This change will further shorten the synchronization period between
   parallel links.

 and node layer

The file name_distr.c currently contains three functions,
named_cluster_distribute(), tipc_publ_subcscribe() and
tipc_publ_unsubscribe() that all directly access fields in
struct tipc_node. We want to eliminate such dependencies, so
we move those functions to the file node.c and rename them to
tipc_node_broadcast(), tipc_node_subscribe() and tipc_node_unsubscribe()
respectively.

Subject: [PATCH 0116/1375] tipc: introduce per-link spinlock

As a preparation to allow parallel links to work more independently
from each other we introduce a per-link spinlock, to be stored in the
struct nodes's link entry area. Since the node lock still is a regular
spinlock there is no increase in parallellism at this stage.

Subject: [PATCH 0117/1375] tipc: convert node lock to rwlock

According to the node FSM a node in state SELF_UP_PEER_UP cannot
change state inside a lock context, except when a TUNNEL_PROTOCOL
(SYNCH or FAILOVER) packet arrives. However, the node's individual
links may still change state.

Since each link now is protected by its own spinlock, we finally have
the conditions in place to convert the node spinlock to an rwlock_t.
If the node state and arriving packet type are rigth, we can let the
link directly receive the packet under protection of its own spinlock
and the node lock in read mode. In all other cases we use the node
lock in write mode. This enables full concurrent execution between
parallel links during steady-state traffic situations, i.e., 99+ %
of the time.

This commit implements this change.

From 5be9c086715c10fb9ae3ffc0ef580dc3a165f98a Mon Sep 17 00:00:00 2001

Subject: [PATCH 0118/1375] tipc: narrow down exposure of struct tipc_node

In our effort to have less code and include dependencies between
entities such as node, link and bearer, we try to narrow down
the exposed interface towards the node as much as possible.

In this commit, we move the definition of struct tipc_node, along
with many of its associated function declarations, from node.h to
node.c. We also move some function definitions from link.c and
name_distr.c to node.c, since they access fields in struct tipc_node
that should not be externally visible. The moved functions are renamed
according to new location, and made static whenever possible.

There are no functional changes in this commit.

Subject: [PATCH 0119/1375] tipc: narrow down interface towards struct
 tipc_link

We move the definition of struct tipc_link from link.h to link.c in
order to minimize its exposure to the rest of the code.

When needed, we define new functions to make it possible for external
entities to access and set data in the link.

Apart from the above, there are no functional changes.

Subject: [PATCH 0120/1375] tipc: eliminate remnants of hungarian notation

The number of variables with Hungarian notation (l_ptr, n_ptr etc.)
has been significantly reduced over the last couple of years.

We now root out the last traces of this practice.
There are no functional changes in this commit.

From 39536ff81e81fef6202612a3ba98aa21fa00c254 Mon Sep 17 00:00:00 2001
From: Ondrej Zary <linux@rainbow-software.org>
Date: Thu, 19 Nov 2015 20:13:04 +0100
Subject: [PATCH 0121/1375] dl2k: Handle memory allocation errors in alloc_list

If memory allocation fails in alloc_list(), free the already allocated
memory and return -ENOMEM. In rio_open(), call alloc_list() first and
abort if it fails. Move HW access (set RFDListPtr) out ot alloc_list().

Subject: [PATCH 0122/1375] dl2k: Reorder and cleanup initialization

Move HW init and stop into separate functions.
Request IRQ only after the HW has been reset (so interrupts are
disabled and no stale interrupts are pending).

Subject: [PATCH 0123/1375] dl2k: Implement suspend

Add suspend/resume support to dl2k driver.
This requires RX/TX rings to be reset so split out the required
functionality from alloc_list() into new rio_reset_ring().

Tested on Asus NX1101 (IP1000A) and D-Link DGE-550T (DL-2000).

Subject: [PATCH 0124/1375] ravb: use clock rate as basis for GTI.TIV

The GTI.TIV may be set to 2GHz^2 / rate, where rate is
that of the clock of the device. Rather than assuming a
rate of 130MHz use the actual rate of the clock.

The motivation for this is to use the correct rate on
the r8a7795/Salvator-X which is advertised as 133MHz but
may differ depending on the extal present on the Salvator-X.

Subject: [PATCH 0125/1375] cgroup: record ancestor IDs and reimplement
 cgroup_is_descendant() using it

cgroup_is_descendant() currently walks up the hierarchy and compares
each ancestor to the cgroup in question.  While enough for cgroup core
usages, this can't be used in hot paths to test cgroup membership.
This patch adds cgroup->ancestor_ids[] which records the IDs of all
ancestors including self and cgroup->level for the nesting level.

This allows testing whether a given cgroup is a descendant of another
in three finite steps - testing whether the two belong to the same
hierarchy, whether the descendant candidate is at the same or a higher
level than the ancestor and comparing the recorded ancestor_id at the
matching level.  cgroup_is_descendant() is accordingly reimplmented
and made inline.

Subject: [PATCH 0133/1375] bnx2x: Utilize FW 7.13.1.0.

Commit 46e8a249423ff "bnx2x: Add FW 7.13.1.0" added said .bin FW to
linux-firmware; This patch incorporates the FW in the bnx2x driver.

This introduces 2 fixes/enhancements:
 - In some management protocols there are outer-vlan configurations
that can be dynamically changed while device is running. This fixes
some corner cases where such a change did not take effect.

 - Prevent VFs from sending MAC control frames; FW would treat a VF
sending such a packet as malicious and block any further communication
done by the VF.

Subject: [PATCH 0135/1375] can: xilinx: Convert to runtime_pm

Instead of enabling/disabling clocks at several locations in the driver,
Use the runtime_pm framework. This consolidates the actions for runtime PM
In the appropriate callbacks and makes the driver more readable and mantainable.

Subject: [PATCH 0137/1375] Bluetooth: Fix powering on with privacy and
 advertising

In order to enable advertising with privacy enabled, SMP has to be
registered in order to generate new RPA. During power on, it will be
registered at the very end which is the reason why advertising is not
enabled and it's not possible to enable it anymore due to mismatch
between hci_dev settings and actual controller state.

This fixes this problem by moving SMP registration earlier, just after
controller is powered (which is ok, because LE SMP will be already able
to decide on identity address to be used), but before advertising is
enabled.

It was wasteful to keep it in the struct because
it can be passed as function argument down the tx
path.

Subject: [PATCH 0146/1375] ath10k: fix tx header parsing

Frames are not guaranteed to be 802.11 frames in
ath10k_htt_tx() and the tx completion handler.
In some cases, like TDLS, they can be Ethernet.
Hence checking, e.g. frame_control could yield
bogus results and behavior.

Fortunately this wasn't a real problem so far
because there's no FW/HW combination to encounter
this problem.

However it is good to fix this in advance.

Fixes: 75d85fd9993c ("ath10k: introduce basic tdls functionality")
Fixes: eebc67fef3ee ("ath10k: fix pmf for wmi-tlv on qca6174")
Fixes: 7b7da0a02192 ("ath10k: drop probe responses when too many are queued")

Subject: [PATCH 0148/1375] ath10k: store msdu_id instead of txbuf pointers

Txbuf is no longer a DMA pool and can be easily
tracked with a mere msdu_id. This saves 10 bytes
on 64bit systems and 6 bytes on 32bit systems of
precious sk_buff control buffer.

Subject: [PATCH 0149/1375] net: dsa: Add support for a switch reset gpio

Some boards have a gpio line tied to the switch reset pin. Allow this
gpio to be retrieved from the device tree, and take the switch out of
reset before performing the probe.

Subject: [PATCH 0157/1375] netfilter: nf_ct_sctp: move ip_ct_sctp away from
 UAPI

ip_ct_sctp is an internal structure, embedded by the union
nf_conntrack_proto to store sctp-specific information at conntrack
entries. It has no business with UAPI.

This patch moves it from UAPI to a saner place, together with similar
structs for other protocols.

Subject: [PATCH 0159/1375] netfilter: ipv6: nf_defrag: avoid/free clone
 operations

commit 6aafeef03b9d9ecf
("netfilter: push reasm skb through instead of original frag skbs")
changed ipv6 defrag to not use the original skbs anymore.

So rather than keeping the original skbs around just to discard them
afterwards just use the original skbs directly for the fraglist of
the newly assembled skb and remove the extra clone/free operations.

The skb that completes the fragment queue is morphed into a the
reassembled one instead, just like ipv4 defrag.

openvswitch doesn't need any additional skb_morph magic anymore to deal
with this situation so just remove that.

A followup patch can then also remove the NF_HOOK (re)invocation in
the ipv6 netfilter defrag hook.

Subject: [PATCH 0160/1375] netfilter: ipv6: avoid nf_iterate recursion

The previous patch changed nf_ct_frag6_gather() to morph reassembled skb
with the previous one.

This means that the return value is always NULL or the skb argument.
So change it to an err value.

Instead of invoking NF_HOOK recursively with threshold to skip already-called hooks
we can now just return NF_ACCEPT to move on to the next hook except for
-EINPROGRESS (which means skb has been queued for reassembly), in which case we
return NF_STOLEN.

Subject: [PATCH 0162/1375] rhashtable-test: retry insert operations

After adding cond_resched() calls to threadfunc(), a surprisingly high
rate of insert failures occurred probably due to table resizes getting a
better chance to run in background. To not soften up the remaining
tests, retry inserts until they either succeed or fail permanently.

Also change the non-threaded test to retry insert operations, too.

Subject: [PATCH 0163/1375] rhashtable-test: calculate max_entries value by
 default

A maximum table size of 64k entries is insufficient for the multiple
threads test even in default configuration (10 threads * 50000 objects =
500000 objects in total). Since we know how many objects will be
inserted, calculate the max size unless overridden by parameter.

Note that specifying the exact number of objects upon table init won't
suffice as that value is being rounded down to the next power of two -
anticipate this by rounding up to the next power of two in beforehand.

It is possible that the PF has not yet assigned resources to the VF.
Although rare, this could result in the VF attempting to read queues it
does not own and result in FUM or THI faults in the PF. To prevent this,
check queue 0 before we continue in init_hw_vf.

Subject: [PATCH 0169/1375] ixgbe: fix multiple kernel-doc errors

The commit dfaf891dd3e1 ("ixgbe: Refactor the RSS configuration code")
introduced a few kernel-doc errors:

1) The function name is missing;
2) The format is wrong;
3) The short description is redundant.

Fix all the above for the correct execution of the kernel doc.

Subject: [PATCH 0170/1375] fm10k: Fix handling of NAPI budget when multiple
 queues are enabled per vector

This patch corrects an issue in which the polling routine would increase
the budget for Rx to at least 1 per queue if multiple queues were present.
This would result in Rx packets being processed when the budget was 0 which
is meant to indicate that no Rx can be handled.

Subject: [PATCH 0173/1375] ixgbevf: Limit lowest interrupt rate for adaptive
 interrupt moderation to 12K

This patch is the ixgbevf version of commit 8ac34f10a5ea4 "ixgbe: Limit
lowest interrupt rate for adaptive interrupt moderation to 12K"

The same logic applies here as well as the same results since a netperf
test will starve for memory in the time from one Tx interrupt to the next.
As a result the ixgbevf driver underperformed when compared to vhost_net.

Subject: [PATCH 0178/1375] ixgbevf: fix spoofed packets with random MAC

If ixgbevf is loaded while the corresponding PF interface is down
and the driver assigns a random MAC address, that address can be
overwritten with the value of hw->mac.perm_addr, which would be 0 at
that point.

To avoid this case we init hw->mac.perm_addr to the randomly generated
address and do not set it unless we receive ACK from ixgbe.

Subject: [PATCH 0179/1375] intel: i40e: fix confused code

This code is pretty confused. The variable name 'bytes_not_copied'
clearly indicates that the programmer knew the semantics of
copy_{to,from}_user, but then the return value is checked for being
negative and used as a -Exxx return value.

I'm not sure this is the proper fix, but at least we get rid of the
dead code which pretended to check for access faults.

Before mroute_reg_vif_num was defined only if any of the CONFIG_PIMSM_
options were set, but that's not really necessary as the size of the
struct is the same in both cases (checked with pahole, both cases size
is 3256 bytes) and we can remove some unnecessary ifdefs to simplify the
code.

Subject: [PATCH 0182/1375] net: ipmr: remove some pimsm ifdefs and simplify

Add the helper pimsm_enabled() which replaces the old CONFIG_IP_PIMSM
define and is used to check if any version of PIM-SM has been enabled.
Use a single if defined(CONFIG_IP_PIMSM_V1) || defined(CONFIG_IP_PIMSM_V2)
for the pim-sm shared code. This is okay w.r.t IGMPMSG_WHOLEPKT because
only a VIFF_REGISTER device can send such packet, and it can't be
created if pimsm_enabled() is false.

Subject: [PATCH 0184/1375] net: ipmr: make ip_mroute_getsockopt more
 understandable

Use a switch to determine if optname is correct and set val accordingly.
This produces a much more straight-forward and readable code.

Subject: [PATCH 0191/1375] net: dsa: include gpio consumer header file

After the introduction of the switch gpio reset API, I'm getting
build errors in configurations that disable CONFIG_GPIOLIB:

net/dsa/dsa.c:783:16: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration]

The reason is that linux/gpio/consumer.h is not automatically
included without gpiolib support. This adds an explicit #include
statement to make it compile in all configurations. The reset
functionality will not work without gpiolib, which is what you
get when disabling the feature.

As far as I can tell, gpiolib is supported on all architectures
on which you can have DSA at the moment.

Subject: [PATCH 0192/1375] net/ipv4/ipconfig: Rejoin broken lines in console
 output

Commit 09605cc12c078306 ("net ipv4: use preferred log methods") replaced
a few calls of pr_cont() after a console print without a trailing
newline by pr_info(), causing lines to be split during IP
autoconfiguration, like:

    .
    ,
     OK
    IP-Config: Got DHCP answer from 192.168.97.254,
    my address is 192.168.97.44

Convert these back to using pr_cont(), so it prints again:

    ., OK
    IP-Config: Got DHCP answer from 192.168.97.254, my address is 192.168.97.44

Absorb the printing of "my address ..." into the previous call to
pr_info(), as there's no reason to use a continuation there.

Convert one more pr_info() to print nameservers while we're at it.

Subject: [PATCH 0195/1375] vrf: remove slave queue and private slave struct

The private slave queue and slave struct haven't been used for anything
and aren't needed, this allows to reduce memory usage and simplify
enslave/release. We can use netdev_for_each_lower_dev() to free the vrf
ports when deleting a vrf device. Also if in the future a private struct
is needed for each slave, it can be implemented via lower devices'
private member (similar to how bonding does it).

Subject: [PATCH 0196/1375] sh_eth: Remove obsolete r7s72100-ether
 platform_device_id entry

Since commit 05104c266ae9a167 ("ARM: shmobile: r7s72100: genmai: Remove
legacy board file"), r7s72100 is only supported in generic DT-only ARM
multi-platform builds.  The driver doesn't need to match platform
devices by name anymore, hence remove the corresponding
platform_device_id entry.

Protect r7s72100_data by #ifdef CONFIG_OF as it's now referenced on DT
platforms only. Move it to a more logical position, in front of the
r8a777x support, so we can have a single #ifdef covering all r7s* and
r8a* support soon. This requires moving a helper function, too.

Subject: [PATCH 0199/1375] sh_eth: Remove obsolete r8a777x-ether
 platform_device_id entry

Since commit 3d7608e4c169af03 ("ARM: shmobile: bockw: remove legacy
board file and config"), R-Car Gen1 SoCs are only supported in generic
DT-only ARM multi-platform builds.  The driver doesn't need to match
platform devices by name anymore, hence remove the corresponding
platform_device_id entry.

Protect sh_eth_set_rate_r8a777x() and r8a777x_data by #ifdef CONFIG_OF,
as they're now referenced on DT platforms only.

Subject: [PATCH 0200/1375] netfilter: Set /proc/net entries owner to root in
 namespace

Various files are owned by root with 0440 permission. Reading them is
impossible in an unprivileged user namespace, interfering with firewall
tools. For instance, iptables-save relies on /proc/net/ip_tables_names
contents to dump only loaded tables.

This patch assigned ownership of the following files to root in the
current namespace:

- /proc/net/*_tables_names
- /proc/net/*_tables_matches
- /proc/net/*_tables_targets
- /proc/net/nf_conntrack
- /proc/net/nf_conntrack_expect
- /proc/net/netfilter/nfnetlink_log

A mapping for root must be available, so this order should be followed:

unshare(CLONE_NEWUSER);
/* Setup the mapping */
unshare(CLONE_NEWNET);

Subject: [PATCH 0202/1375] netfilter: nft_payload: add packet mangling support

Add support for mangling packet payload. Checksum for the specified base
header is updated automatically if requested, however no updates for any
kind of pseudo headers are supported, meaning no stateless NAT is supported.

For checksum updates different checksumming methods can be specified. The
currently supported methods are NONE for no checksum updates, and INET for
internet type checksums.

There's no need to kill the thread and eventually the kernel in this

so just complain that we're here and move along.

There's really no reason to kill the kernel thread just because of a
little info string. This reworks the code to use snprintf's limiting to
assure that the string is never too long, and WARN_ON to still put out
a warning that we might want to look at the feature list length.

There's no need to kill the kernel thread here. If this condition was

we'll get the same result when this code tries to use the VSI pointer
being checked.

HW/NVM sets a limit of no less than 256 bytes for MSS. Stack can send as
low as 76 bytes MSS. This patch lowers the HW limit to 64 bytes to avoid
MDDs from firing and causing a reset when the MSS is lower than 256.

Subject: [PATCH 0210/1375] i40e/i40evf: Add a stat to track how many times we
 have to do a force WB

When in NAPI with interrupts disabled, the HW needs to be forced to do a
write back on TX if the number of descriptors pending are less than a
cache line.

This stat helps keep track of how many times we get into this situation.

Subject: [PATCH 0211/1375] i40e: Move the saving of old link info from
 handle_link_event to link_event

The watchdog only calls link_event not handle_link_event which means
that we need to save the old information in link_event.

Previously when polling we were comparing current data to the old data
saved the last time we actually received a link event. This means that
the polling would only fix link status changes in one direction
depending on what the last old data saved off was.

Subject: [PATCH 0214/1375] i40evf: handle many MAC filters correctly

When a lot (many hundreds) of MAC or VLAN filters are added at one time,
we can overflow the Admin Queue buffer size with all the requests.
Unfortunately, the driver would then calculate the message size
incorrectly, causing it to be rejected by the PF. Furthermore, there was
no mechanism to trigger another request to allow for configuring the
rest of the filters that didn't fit into the first request.

To fix this, recalculate the correct buffer size when we detect the
overflow condition instead of just assuming the max buffer size. Also,
don't clear the request bit in adapter->aq_required when we have an
overflow, so that the rest of the filters can be processed later.

Subject: [PATCH 0215/1375] i40e: return the number of enabled queues for
 ETHTOOL_GRXRINGS

This patch fixes a problem where using ethtool rxnfc command could
let RX flow hash be set on disabled queues. This patch fixes the
problem by returning the number of enabled queues before setting
rxnfc.

Subject: [PATCH 0217/1375] i40e: create a generic configure rss function

This patch renames the old pf-specific function in order to clarify
its scope. This patch also creates a more generic configure RSS
function with the old name.

This patch also creates a new more generic function to get RSS
configuration, using the appropriate method.

From c9c0043894cf2666ae832fbad7afa68fa53178ac Mon Sep 17 00:00:00 2001
From: Hante Meuleman <meuleman@broadcom.com>
Date: Thu, 29 Oct 2015 20:33:12 +0100
Subject: [PATCH 0220/1375] brcmfmac: Simplify and fix usage of brcmf_ifname.

brcmf_ifname is a debug function to return a name related to an ifp,
but is using a rather complex implementation. It was also used
wrongly from bcdc as it did not use the bsscfgidx as it was supposed
to, but bssidx. This patch fixes that bug and simplifies
brcmf_ifname.

Subject: [PATCH 0221/1375] brcmfmac: Remove unnecessary check from start_xmit.

The brcmf_netdev_start_xmit checks if the ndev is still valid by
checking if it still exists in database. This check is not needed
and therefor removed.

Currently runtime pm is enabled for USB, but it is not properly
supported by driver. This patch disables the runtime PM support
completely for USB, as it currently can result in problems on
some systems.

Subject: [PATCH 0224/1375] brcmfmac: Add RSDB support.

Broadcom devices with a single 802.11 core can work on two band
concurrently using VSDB feature, ie. Virtual Simultaneous Dual-Band.
For devices that are fitted with two 802.11 cores and RF paths the
driver should support a firmware feature called RSDB, which stands
for Real Simultaneous Dual-Band. RSDB works almost autonomously in
firmware except for AP config. When the device supports RSDB then
the interface should not be brought down when configuring it,
otherwise the link (if configured) on the other interface will be
lost.

Subject: [PATCH 0225/1375] brcmfmac: Use consistent naming for bsscfgidx.

The variable bsscfgidx is used in different places with different
names, e.g. bsscfg, bssidx, bsscfg_idx. This patch cleans this up
by using bsscfgidx everywhere.

From c2a43a6ba5e56b4bbca46287628ef1c84c44fa8d Mon Sep 17 00:00:00 2001
From: Hante Meuleman <meuleman@broadcom.com>
Date: Thu, 29 Oct 2015 20:33:18 +0100
Subject: [PATCH 0226/1375] brcmfmac: Use new methods for pcie Power
 Management.

Currently the legacy methods suspend and resume are used for pcie
devices. This is not the preferable method and is also causing
issues with some setups when doing hibernate. Changing this to
use the new PM methods.

Subject: [PATCH 0227/1375] brcmfmac: Add wowl wake indication report.

On wakeup of the system (resume) a wowl wakeup indication report
can be sent to cfg80211. This patch adds support for this. The
report specifies if the device was responsible for the wakeup
and if so, will specify the exact reason.

If kzalloc fails it will return NULL. Lets check for NULL first before
using the pointer.

Subject: [PATCH 0234/1375] iwlwifi: nvm: fix up phy section when reading it

This is a workaround to an OTP bug. In Series 8000 1x1, the OTP
0xA052 defines 2x2 antenna configuration. This workaround overrides
the decision based on HW id and on MIMO disabled bit which is
correct in the OTP and set to disabled. This fixes the previous
workaround "force 1x1 antenna in Series 8000".

Subject: [PATCH 0235/1375] iwlwifi: add support for 12K Receive Buffers

802.11ac allows A-MSDU that can be up to 12KB long. Since
an entire A-MSDU needs to fit into one single Receive
Buffer (RB), add support for big RBs.
Since this adds lots of pressure to the memory manager and
significantly increase the true_size of the RX buffers,
don't enable this by default.

Subject: [PATCH 0236/1375] iwlwifi: dvm: remove Kconfig default

The split of iwlwifi into DVM and MVM was a long time ago now,
so we can remove the "default IWLWIFI" that we had to keep all
existing .config files with working defaults during the split.
This is no longer necessary, practically nobody should now be
upgrading a .config that's older than the split.

Subject: [PATCH 0238/1375] iwlwifi: mvm: Configure fragmented scan for
 scheduled scan

Configure the FW to use fragmented scan when the traffic load is high
or low latency traffic is on. This is useful for scans that are
managed by the FW (e.g. scheduled scan).

Subject: [PATCH 0240/1375] iwlwifi: mvm: Enable MPLUT only on supported hw

When there's a bt-wifi contention that requires arbitration,
we use a priority-based mechanism to decide which comm wins.
Over time, use cases become more and more complex, with multiple
concurrent active links with different traffic types and different QoS
requirements, on both WiFi and BT sides.
This, in turn, requires us to elaborate our prioritization mechanism.
However, our legacy products included hw that does not supports this,
so selectively enable this on specific hw - as signaled by the firmware.

In case of using an external NVM file, the driver sends to the
FW the different nvm sections. In the response of the cmd, the
FW states the status of the writing of the chunk.

Currently the value is not checked by the driver.

Check FW's response for writing the nvm chunk in the NVM_ACCESS_CMD.

Subject: [PATCH 0247/1375] iwlwifi: mvm: add trigger for firmware dump upon
 TDLS events

This will allow to catch different TDLS events and get the
firmware data when they occur.
Add empty TX_LATENCY trigger on the way to avoid mismatch
with trees in which this trigger is implemented.

Subject: [PATCH 0252/1375] iwlwifi: mvm: drop low_latency_agg_frame_cnt_limit

This was an old workaround for solving latency issues with
certain Miracast adapters like ActionTec. However this isn't
needed anymore and furthermore it hurts throughput in other
use cases.

Subject: [PATCH 0253/1375] iwlwifi: export the _no_grab version of PRPH IO
 functions

Expose _no_grab prph i/o functions that allow performing i/o
outside the transport, without requiring grab and release NIC access
for each operation. In addition, rename the functions so they reflect
their non-grabbing behavior.

This can be very useful for consecutive prph i/o operation that occur
outside trans, such as fw dumps.

Subject: [PATCH 0254/1375] iwlwifi: dump prph registers in a common place for
 all transports

Currently the prph registers dump is in the transport layer,
and each bus needs an additional dump implementation.

Move the prph dump outside transport, and allow a common
implementation for all of the buses.
This is possible because prph base addresses are similar for
all buses.

Subject: [PATCH 0255/1375] iwlwifi: mvm: flush all used TX queues before
 suspending

There is a potential race condition when entering suspend with d0i3 in
PCIe.  If there is a frame queued just before we suspend, it won't
complete and we will never clear the queue stuck timer.  To solve
this, call TX_PATH_FLUSH to flush all queues (except the command
queue) as part of the d0i3 entry process.  Add a new function that
returns all the flushable queues.

 iwl_mvm_is_d0i3_supported()

The d0i3_mode element is never set to IWL_D0I3_OFF, so it's not
necessary to check it in iwl_mvm_is_d0i3_supported().

Subject: [PATCH 0257/1375] wcn36xx: introduce WCN36XX_HAL_AVOID_FREQ_RANGE_IND

WCN3620 firmware introduces a new async indication, we need to
add it as a known message type so we can accept it

Subject: [PATCH 0258/1375] wcn36xx: swallow two wcn3620 IND messages

WCN3620 can asynchronously send two new kinds of indication message,
since we can't handle them just accept them quietly.

Subject: [PATCH 0259/1375] wcn36xx: handle new hal response format

wcn3620 has a new message structure for the reply to some hal
commands.  This patch adds the struct and helper routine that
uses it if the chip is wcn3620, or falls back to the old
helper routine.

We don't know what to do with the candidate list he sends back,
but we can at least accept and ignore it nicely instead of dying.

Subject: [PATCH 0263/1375] brcmfmac: Return actual error by fwil.

FWIL is always mapping back errors to EBADE. This is not very
conventient when trying to understand problems by reading logs.
Some callers print the error code, but that is quite useless
when the exact error code is not returned. It also makes it
impossible to differentiate based on error code. This patch
changes the return of EBADE into the actual error code.

Subject: [PATCH 0264/1375] brcmfmac: Change error print on wlan0 existence.

During initialization of the device, but also on some other
moments the driver prints an error that the netdev already exists.
This is a result of the way the driver is initializing the
firmware and not really an error. The code is not treating it as
an error either. This error print has resulted in many questions
by users and is confusing and incorrect. This patch changes the
error log into a debug info log.

Aborting the current read attempt on the superframe also removes the
packet from the pipeline. Retries should not be attempted on the next
packet since it would not be a superframe(either a superframe descriptor
or other data packet) and should not be handled by brcmf_sdio_rxglom

Subject: [PATCH 0269/1375] brcmfmac: assure net_ratelimit() is declared before
 use

Under some kernel configuration we get build issue with implicit
declaration of net_ratelimit() function. Fix this by explicitly
including the file providing the prototype.

Subject: [PATCH 0270/1375] brcmfmac: Unify methods to define and map firmware
 files.

All bus drivers (sdio, usb and pcie) require firmware files which
needs to be downloaded to the device, The definitions and mapping
of device id and revision to firmware and nvram file is done by
each bus driver. This patch creates common functions and defines
to simplify and unify the definition of these firmware and nvram
files and mapping.

Subject: [PATCH 0272/1375] rt2x00: type bug in _rt2500usb_register_read()

This code causes a static checker bug.

drivers/net/wireless/ralink/rt2x00/rt2500usb.c:232 _rt2500usb_register_read()
warn: passing casted pointer 'value' to 'rt2500usb_register_read()' 32 vs 16.

If the low 16 bits were initialized to zero then this code would only be
a problem on big endian systems.  But in this case this is case the low
16 bits are never initialized.  This is called from a function which is
created using a macro:

RT2X00DEBUGFS_OPS(csr, "0x%.8x\n", u32);

We end up copying uninitialized data to the user which is bogus and an
information leak.

Subject: [PATCH 0278/1375] ath10k: stop abusing GFP_DMA

Allocations from the DMA zone were originally added for legacy ISA
stuff, or PCI devices that have specific limitations in their DMA
addressing capabilities. It has no place in ath10k, which can do
full 32-bit DMA.

Fixes memory allocation errors on some platforms.

Subject: [PATCH 0282/1375] ath10k: apply Mesh subtype when Mesh interface
 created.

QCA988X firmware starting from 10.2.4.70.12-2 has capability to support
Mesh Control Field Present bit in QoS field in native Wi-Fi mode.
Hence apply Mesh subtype according to the WMI service map.

Firmware will allows unicast, broadcast, multicast, and WDS frame
(FromDS = 1 and ToDS = 1) to be received via the interface, once Mesh
subtype is used.

The firmware and this patch together make native Wi-Fi mode comply to
IEEE802.11s Mesh frame in open mode, but the firmware doesn't yet
support secured Mesh mode.

 initialisation

Earlier we printed all the info messages after a successful device
initialisation and firmware boot, but that's problematic if something goes
wrong and there's no easy way to know what firmware version was used and so on.

Split the info messages into smaller pieces and print them as soon as we have
the info available.

Subject: [PATCH 0288/1375] ath10k: implement fw_checksums debugfs file

When debugging firmware problems it's useful to check checksums of each
component. Add a debugfs interface to retrieve crc32 checksums:

# cat /sys/kernel/debug/ieee80211/phy0/ath10k/fw_checksums
firmware-N.bin          cc3fb466
athwlan                 c0089f21

Subject: [PATCH 0289/1375] net: Generalise wq_has_sleeper helper

The memory barrier in the helper wq_has_sleeper is needed by just
about every user of waitqueue_active.  This patch generalises it
by making it take a wait_queue_head_t directly.  The existing
helper is renamed to skwq_has_sleeper.

It looks like many files are including mroute.h unnecessarily, so remove
the include. Most importantly remove it from ipv6.

Subject: [PATCH 0297/1375] net: ipmr: remove unused MFC_NOTIFY flag and make
 the flags enum

MFC_NOTIFY was introduced in kernel 2.1.68 but afaik it hasn't been used
and I couldn't find any users currently so just remove it. Only
MFC_STATIC is left, so move it into an enum, add a description and use
BIT().

Subject: [PATCH 0302/1375] net: ipmr: add mfc newroute/delroute netlink
 support

This patch adds support to add and remove MFC entries. It uses the
same attributes like the already present dump support in order to be
consistent. There's one new entry - RTA_PREFSRC, it's used to denote an
MFC_PROXY entry (see MRT_ADD_MFC vs MRT_ADD_MFC_PROXY).
The already existing infrastructure is used to create and delete the
entries, the netlink message gets converted internally to a struct mfcctl
which is used with ipmr_mfc_add/delete.
The other used attributes are:
RTA_IIF - used for mfcc_parent (when adding it's required to be valid)
RTA_SRC - used for mfcc_origin
RTA_DST - used for mfcc_mcastgrp
RTA_TABLE - the MRT table id
RTA_MULTIPATH - the "oifs" ttl array

Subject: [PATCH 0303/1375] iwlwifi: mvm: move fw-dbg code to separate file

The fw debug functionality is big enough to warrant
a separate file. Move existing related functions to the new file.

Subject: [PATCH 0304/1375] iwlwifi: mvm: Support setting continuous recording
 debug mode

Add ability to set the continuous recording mode of the FW, while
the FW debug data is configured to be stored on the NIC.
This could be useful for storing large segments of FW usniffer
debug data on the host, while having small store space on the NIC.
The host receives the usniffer data through the regular RX path, and
the data can get extracted using trace-cmd.

Subject: [PATCH 0305/1375] iwlwifi: clean up transport debugfs handling

Transport code currently calls itself through the transport ops,
which is quite pointless. Clean up all of this. While at it,
remove the unnecessary dir argument and the redundant IDI code.

In slave transports, call both the common slave debugfs and the
transport's own. SDIO has no files, so remove it all there.

Subject: [PATCH 0307/1375] iwlwifi: mvm: fix incorrect fallthrough in
 iwl_mvm_check_running_scans()

In the iwl_mvm_check_running_scans() we were mistakenly ignoring the
value returned by iwl_mvm_scan_stop() for scheduled scans and falling
thorugh to the next case, which caused us to always return zero.

Subject: [PATCH 0308/1375] iwlwifi: mvm: use firmware station lookup, combine
 code

In most cases, the firmware will already match the station that
we received a given frame from and tell us the station ID in the
RX status, so we can look up the station from that. This lets us
skip the (more expensive) hash table lookup in mac80211.

Also change the fallback case (no station info from the firmware)
to not attempt to look up a multicast source address.

While at it, also combine all the code using the station into a
single if block.

Subject: [PATCH 0309/1375] iwlwifi: mvm: refactor d3 key update functions

We need to reuse the key update logic for d0i3
as well.

Add some parameters to deal with the constraints
implied by the d0i3 flow (specifically, support
non-SYNC commands, and don't take mutexes that
might deadlock).

Change some commands to be ASYNC, in order
to simplify locking a bit.

Subject: [PATCH 0310/1375] iwlwifi: Add new PCI IDs for 9260 and 5165 series

Add 9000-family configuration to iwl_cfg struct
Add a new struct to define the 5165 series.
Rename the struct that defines the 9000 series to 9260.
Add some new sub-system IDs for the 9260 and 5165 series.
For 9260:
0x0A10, 0x0000, 0x0510, 0x0710, 0x0410, 0x0610.
For 5165:
0x2A10, 0x2010, 0x0310, 0x0210.

Date: Sat, 21 Nov 2015 21:57:52 +0100
Subject: [PATCH 0315/1375] iwlwifi: print index in api/capa flags parsing
 message

If the API or capabilities index is bigger than the driver expects,
an error message is printed. Make that message print the index and
distinguish between API and capabilities.

Subject: [PATCH 0319/1375] iwlwifi: mvm: ROC: Extend the ROC max delay
 duration & limit ROC duration

When associated to an AP and a ROC event with a long duration is scheduled
the FW may have a hard time scheduling a consecutive time event, since it
has to remain on the connection channel to hear the AP's DTIM.
In addition, when associated and a ROC is requested with a duration
greater than the DTIM interval, the FW will not be able to schedule
the ROC event, since it needs to wake up for the DTIM.

Increasing the "max delay" duration to the DTIM period will allow the FW to
wait until after the DTIM and then schedule the ROC time event.
Limiting the ROC to be less than the DTIM interval will assure that the
time event will be scheduled for at least part of the time (instead of
automatically failing)

Extend the ROC max delay duration to min(dtim_interval * 3, 600TU),
and limit the duration to be less than the DTIM interval.

Subject: [PATCH 0321/1375] unix: use wq_has_sleeper in unix_dgram_recvmsg

The current unix_dgram_recvmsg does a wake up for every received
datagram. This seems wasteful as only SOCK_DGRAM client sockets in an
n:1 association with a server socket will ever wait because of the
associated condition. The patch below changes the function such that the
wake up only happens if wq_has_sleeper indicates that someone actually
wants to be notified. Testing with SOCK_SEQPACKET and SOCK_DGRAM socket
seems to confirm that this is an improvment.

Subject: [PATCH 0322/1375] hv_netvsc: rework link status change handling

There are several issues in hv_netvsc driver with regards to link status
change handling:
- RNDIS_STATUS_NETWORK_CHANGE results in calling userspace helper doing
  '/etc/init.d/network restart' and this is inappropriate and broken for
  many reasons.
- link_watch infrastructure only sends one notification per second and
  in case of e.g. paired disconnect/connect events we get only one
  notification with last status. This makes it impossible to handle such
  situations in userspace.

Redo link status changes handling in the following way:
- Create a list of reconfig events in network device context.
- On a reconfig event add it to the list of events and schedule
  netvsc_link_change().
- In netvsc_link_change() ensure 2-second delay between link status
  changes.
- Handle RNDIS_STATUS_NETWORK_CHANGE as a paired disconnect/connect event.

Subject: [PATCH 0323/1375] net: add support for netdev notifier error
 injection

This module allows to insert errors in some of netdevice's notifier
events. All network drivers use these notifiers to signal various events
and to check if they are allowed, e.g. PRECHANGEMTU and CHANGEMTU
afterwards. Until recently I had to run failure tests by injecting
a custom module, but now this infrastructure makes it trivial to test
these failure paths. Some of the recent bugs I fixed were found using
this module.
Here's an example:
 $ cd /sys/kernel/debug/notifier-error-inject/netdev
 $ echo -22 > actions/NETDEV_CHANGEMTU/error
 $ ip link set eth0 mtu 1024
 RTNETLINK answers: Invalid argument

Subject: [PATCH 0328/1375] qed: Add support for changing LED state

Physical LEDs are being controlled by the management FW.
This adds the qed functionality required to request management FW to
change the LED configuration, as well as the necessary APIs for this
functionality to later be used by the protocol drivers.

Subject: [PATCH 0332/1375] stmmac: support Reg_9 to get HW level information

For GMAC newer than 3.40a there is a new register (Reg_9) that provides the
status of all modules of the transmit and receive paths and FIFO status.
These can be exposed via ethtool.

Subject: [PATCH 0333/1375] isdn: remove spellcaster driver

The 'sc' ISDN driver relies on using readl() to access ISA I/O memory.
This has been deprecated and produced warnings since linux-2.3.23,
disabled by default since 2.4.10 and finally removed in 2.6.5.

I found this because the compiling the driver for ARM produces
a warning:

In file included from ../drivers/isdn/sc/includes.h:8:0,
                 from ../drivers/isdn/sc/init.c:13:
../arch/arm/include/asm/io.h:115:21: note: expected 'const volatile void *' but argument is of type 'long unsigned int'

It is pretty clear that this driver has not been used for a long time
and there is no point fixing it now, so let's remove it.

Subject: [PATCH 0335/1375] i40e: rename rss_size to alloc_rss_size in i40e_pf

This patch renames rss_size to alloc_rss_size in i40e_pf, which is
clearer and avoids confusion. It also adds comments to the other
related structure members to help clarify usage.

Subject: [PATCH 0336/1375] i40e/i40evf: Fix RS bit update in Tx path and
 disable force WB workaround

This patch fixes the issue of forcing WB too often causing us to not
benefit from NAPI.

Without this patch we were forcing WB/arming interrupt too often taking
away the benefits of NAPI and causing a performance impact.

With this patch we disable force WB in the clean routine for X710
and XL710 adapters. X722 adapters do not enable interrupt to force
a WB and benefit from WB_ON_ITR and hence force WB is left enabled
for those adapters.
For XL710 and X710 adapters if we have less than 4 packets pending
a software Interrupt triggered from service task will force a WB.

This patch also changes the conditions for setting RS bit as described
in code comments. This optimizes when the HW does a tail bump amd when
it does a WB. It also optimizes when we do a wmb.

Subject: [PATCH 0337/1375] i40e/i40evf: prefetch skb data on transmit

Issue a prefetch for data early in the transmit path.
This should not be generally needed for Tx traffic, but
it helps immensely for pktgen workloads and should help
for forwarding workloads as well.

There are two ways to configure RSS, this patch adjusts those two
functions with the same input parameters, and creates a more
generic function for configuring RSS.

Subject: [PATCH 0340/1375] i40evf: create a generic get RSS function

There are two ways to get RSS, this patch implements two functions
with the same input parameters, and creates a more generic function
for getting RSS configuration.

Subject: [PATCH 0342/1375] i40e: Update error messaging

This patch fixes an issue where adminq init failures always provided
a message that NVM was newer than expected.  This is not always the
case for init_adminq failures. Without this patch, if adminq init
fails for any reason, newer NVM message would be given.  This
problem is fixed by adding  a check for that specific error
condition and a different hopefully helpful message otherwise.

If we get an invalid message from a VF, we should tell the user which VF
is being naughty, rather than making them guess.

Subject: [PATCH 0345/1375] i40evf: quoth the VF driver, Nevermore

If, upon a midnight dreary, the PF returns ERR_PARAM when the VF is
requesting resources, that's fatal. Either the firmware or NVM is badly,
badly misconfigured, or this VF has been disabled due to a previous VF
driver sending a bunch of bogus messages.

Either way, there is no recovery from this. Don't ponder weak and weary,
just quit.

Subject: [PATCH 0346/1375] i40evf: allocate queue vectors dynamically

Change the queue_vector array from a statically-sized member of the
adapter structure to a dynamically-allocated and -sized array.

This reduces the size of the adapter structure, and allows us to support
any number of queue vectors in the future without changing the code.

Subject: [PATCH 0347/1375] i40evf: allocate ring structs dynamically

Instead of awkwardly keeping a fixed array of pointers in the adapter
struct and then allocating ring structs individually, just keep a single
pointer and allocate a single blob for the arrays. This simplifies code,
shrinks the adapter structure, and future-proofs the driver by not
limiting the number of rings we can handle.

Subject: [PATCH 0349/1375] i40e: fix: do not sleep in netdev_ops

The driver was being called by VLAN, bonding, teaming operations
that expected to be able to hold locks like rcu_read_lock().

This causes the driver to be held to the requirement to not sleep,
and was found by the kernel debug options for checking sleep
inside critical section, and the locking validator.

Subject: [PATCH 0350/1375] i40e: remove unused argument

With the final edition of the patches to remove sleeps from
the driver's entry points, the grab_rtnl argument is no
longer needed, so partially revert the commit that added it.

Subject: [PATCH 0358/1375] hv_netvsc: Don't ask for additional head room in
 the skb

The rndis header is 116 bytes big and can be placed in the default
head room that will be available in the skb. Since the netvsc packet
is less than 48 bytes, we can use the skb control buffer
for the netvsc packet. With these changes we don't need to
ask for additional head room.

Subject: [PATCH 0360/1375] hv_netvsc: remove locking in netvsc_send()

Packet scheduler guarantees there won't be multiple senders for the same
queue and as we use q_idx for multi_send_data the spinlock is redundant.

Subject: [PATCH 0368/1375] tcp: suppress too verbose messages in
 tcp_send_ack()

If tcp_send_ack() can not allocate skb, we properly handle this
and setup a timer to try later.

Use __GFP_NOWARN to avoid polluting syslog in the case host is
under memory pressure, so that pertinent messages are not lost under
a flood of useless information.

sk_gfp_atomic() can use its gfp_mask argument (all callers currently
were using GFP_ATOMIC before this patch)

We rename sk_gfp_atomic() to sk_gfp_mask() to clearly express this
function now takes into account its second argument (gfp_mask)

Note that when tcp_transmit_skb() is called with clone_it set to false,
we do not attempt memory allocations, so can pass a 0 gfp_mask, which
most compilers can emit faster than a non zero or constant value.

Future devices will allow for more queue pairs, so allocate a netdev
that can handle them. While we're at it, get rid of the separate
MAX_TX/MAX_RX defines. Since we always get matched queue pairs, having
these makes no sense.

 moved to service_task from tx_timeout

This patch contains following changes:
   - detection and recovery logic (issue SW interrupt) has been moved to
     service_task from timeout function.
   - added some more debug info from tx_timeout.

Logic to detect and recover TX queue hung is now two step process:
  - service_task detects TX queue hung and sets a bit(hung_detected) if
    it was not set.
  - if bit was set (means this is back-back hung condition detected),
    issue SW interrupt and clear the bit.
  - napi_poll clears the bit unconditionally since it cleans TX/RX queues.

Subject: [PATCH 0374/1375] i40e: Fix memory leaks, sideband filter programming

This patch fixes the memory leak which would be seen otherwise when user
programs flow-director filter using ethtool (sideband filter programming).

When ethtool is used to program flow directory filter, 'raw_buf' gets
allocated and it is supposed to be freed as part of queue cleanup. But
check of 'tx_buffer->skb' was preventing it from being freed.

These allocations don't need to be at atomic level. GFP_KERNEL is fine
and they'll reduce stress on the allocator when the system is starved
for memory.

Subject: [PATCH 0376/1375] i40e: propagate properly

i40e_sync_vsi_filters() is the surly teenager of this driver. It says
it's going to report errors, but it doesn't actually do that most of the
time. And when it does, it leaves a mess.

Change this function to have a common exit point so it will properly
release the busy lock on the VSI. Propagate errors to the callers.
Finally, adjust a few callers to check for and deal with errors from
this function.

Subject: [PATCH 0378/1375] i40e: use priv flags to control packet split

Ethtool priv flags implementation to enable or disable packet split, which
is a hardware feature that inspects headers and will put headers in a
separate DMA buffer from the payload data.  The driver was automatically
choosing to enable packet split in some cases and this gives the user the
ability to turn it off/on explicitly.

to query state:
ethtool --show-priv-flags ethx

to enable:
ethtool --set-priv-flags ethx packet-split on
to disable:
ethtool --set-priv-flags ethx packet-split off

Why would anyone want this?
	Because some environments benefit from header/data split in the receive
	buffer, and the driver defaults to one or the other depending on
	environment/kernel parameters.

Why didn't you implement a generic ethtool control for this feature?
	Because Intel hardware is the only hardware that supports header/data
	split.

Subject: [PATCH 0379/1375] i40e: remove CONFIG_I40E_VXLAN

Instead of having our own custom symbol, we can just rely
on whether or not the kernel has the feature enabled.

In this case use IS_ENABLED(CONFIG_VXLAN) in order to handle
built-in or module in the current BKM way.

Subject: [PATCH 0380/1375] i40e: Remove separate functions gathering XOFF Rx
 stats

The separate functions to gather Flow control Rx XOFF stats was to
determine if the Tx for a queue was paused due to Link Flow Control(LFC)
or Priority Flow Control(PFC).

But, with recent change in the i40e driver the logic for checking th Tx
hang has been removed and these functions don't do anything meaningful.
Hence, there is no need to keep these separate functions to gather Rx
XOFF stats for LFC or PFC.

This patch removes these functions and moves the stat collection for
XOFF Rx to the i40e_update_pf_stats() that collects all the PF stats.

We shouldn't be using a bitwise operator here; it's not a bitwise
operation. Use a logical operator instead. Why doesn't c have a
logical-or-and-assign operator?

Subject: [PATCH 0385/1375] ixgbe: Prevent KR PHY reset in
 ixgbe_init_phy_ops_x550em

This patch removes KR PHY reset from ixgbe_init_phy_ops_x550em,
since this function is meant to initialize function pointers for
the detected PHY type. Internal PHY reset was moved to
ixgbe_setup_internal_phy_t_x550em which will now detect which
mode the internal PHY operates in and set it up as required.

Subject: [PATCH 0390/1375] ixgbe: Refactor MAC address configuration code

In the process of tracking down a memory leak when adding/removing FDB
entries I had to go through the MAC address configuration code for ixgbe.
In the process of doing so I found a number of issues that impacted
readability and performance.  This change updates the code in general to
clean it up so it becomes clear what each step is doing.  From what I can
tell there a couple of bugs cleaned up in this code.

First is the fact that the MAC addresses were being double counted for the
PF.  As a result once entries up to 63 had been used you could no longer
add additional filters.

A simple test case for this:
  for i in `seq 0 96`
  do
    ip link add link ens8 name mv$i type macvlan
    ip link set dev mv$i up
  done

Test script:
  ethregs -s 0:8.0 | grep -e "RAH" | grep 8000....$

When things are working correctly RAL/H registers 1 - 97 will be consumed.
In the failing case it will stop at 63 and prevent any further filters from
being added.

Subject: [PATCH 0391/1375] ixgbe: Use __dev_uc_sync and __dev_uc_unsync for
 unicast addresses

This change replaces the ixgbe_write_uc_addr_list call in ixgbe_set_rx_mode
with a call to __dev_uc_sync instead.  This works much better with the MAC
addr list code that was already in place and solves an issue in which you
couldn't remove an FDB address without having to reset the port.

Subject: [PATCH 0392/1375] ixgbe: Allow FDB entries access to more RAR filters

This change makes it so that we allow the PF to make use of all free RAR
entries for FDB use if needed.

Previously the code limited us to 16 unicast entries, however this was
shared between MACVLAN which wasn't limited and the FDB code which was.  So
instead of treating the FDB code as a second class citizen I have updated
it so that it has access to just as many entries as the MACVLAN filters.

Subject: [PATCH 0393/1375] ixgbe: Update PTP to support X550EM_x devices

The X550EM_x devices handle clocking differently, so update the
PTP implementation to accommodate them. This involves significant
changes to ixgbe's PTP code to accommodate the new range of
behaviors including things like non-power-of-2 clock wrapping.

+ *
+ * This results in a full 96 bits to represent the clock, with 32 bits for
+ * seconds, 32 bits for nanoseconds (largest value is 0d999999999 or just under
+ * 1 second) and an additional 32 bits to measure sub nanosecond adjustments for
+ * underflow of adjustments.
+ *
+ * The 32 bits of seconds for the X550 overflows every
+ *   2^32 / ( 365.25 * 24 * 60 * 60 ) = ~136 years.
+ *
+ * In order to adjust the clock frequency for the X550, the TIMINCA register is
+ * provided. This register represents a + or minus nearly 0.5 ns adjustment to
+ * the base frequency. It is measured in 2^-32 ns units, with the high bit being
+ * the sign bit. This register enables software to calculate frequency
+ * adjustments and apply them directly to the clock rate.
+ *
+ * The math for converting ppb into TIMINCA values is fairly straightforward.
+ *   TIMINCA value = ( Base_Frequency * ppb ) / 1000000000ULL
+ *
+ * This assumes that ppb is never high enough to create a value bigger than
+ * TIMINCA's 31 bits can store. This is ensured by the stack. Calculating this
+ * value is also simple.
+ *   Max ppb = ( Max Adjustment / Base Frequency ) / 1000000000ULL
+ *
+ * For the X550, the Max adjustment is +/- 0.5 ns, and the base frequency is
+ * 12.5 nanoseconds. This means that the Max ppb is 39999999
+ *   Note: We subtract one in order to ensure no overflow, because the TIMINCA
+ *         register can only hold slightly under 0.5 nanoseconds.
+ *
+ * Because TIMINCA is measured in 2^-32 ns units, we have to convert 12.5 ns
+ * into 2^-32 units, which is
+ *
+ *  12.5 * 2^32 = C80000000
+ *
+ * Some revisions of hardware have a faster base frequency than the registers
+ * were defined for. To fix this, we use a timecounter structure with the
+ * proper mult and shift to convert the cycles into nanoseconds of time.

Subject: [PATCH 0394/1375] ixgbe: Correct spec violations by waiting after
 reset

The ixgbe driver was violating the specification in the datasheet
by not waiting 1ms before checking for the reset bit clearing. This
is called out for devices supported by ixgbe, so implement the
required delay.

to Alexander Duyck for recognizing problems with the first version
of this patch and recognizing how to coalesce error conditions
into a single location.

is present. Consequently, PHY power will always be turned on when
requested. Without this patch, some systems with X540 or X550
devices in some conditions will never get link.

Subject: [PATCH 0399/1375] ixgbevf: Handle extended IPv6 headers in Tx path

Check for and handle IPv6 extended headers so that Tx checksum
offload can be done. Also use skb_checksum_help for unexpected
cases. Thanks to Tom Herbert for noticing these problems. Thanks
to Alexander Duyck for seeing how to coalesce the error handling
into one location.

Subject: [PATCH 0400/1375] i40e: Fix i40e_print_features() VEB mode output

Commit 7fd89545f337 ("i40e: remove BUG_ON from feature string building")
added defective output when I40E_FLAG_VEB_MODE_ENABLED was set in
function i40e_print_features.

Fix it.

Miscellanea:

- Remove unnecessary string variable
- Add space before not after fixed strings
- Use kmalloc not kzalloc
- Don't initialize i to 0, use result of first snprintf

switchdev drivers reflect the newly requested topology to hardware when
CHANGEUPPER is received, after software links were already formed.
However, the operation can fail and user will not be notified, as the
return value of the notifier is not checked.

Add this check and rollback software links if necessary.

Subject: [PATCH 0407/1375] net: add netif_is_lag_port helper

Subject: [PATCH 0409/1375] net: add possibility to pass information about
 upper device via notifier

Sometimes the drivers and other code would find it handy to know some
internal information about upper device being changed. So allow upper-code
to pass information down to notifier listeners during linking.

Subject: [PATCH 0413/1375] net: introduce change lower state notifier

When lower device like bonding slave, team/bridge port, etc changes its
state, it is useful for others to notice this change. Currently this is
implemented specificly for bonding as NETDEV_BONDING_INFO notifier. This
patch aims to replace this specific usage and make this more generic to
be used for all upper-lower devices.

Introduce NETDEV_CHANGELOWERSTATE netdev notifier type and
netdev_lower_state_changed() helper.

Subject: [PATCH 0417/1375] bonding: allow notifications for
 bond_set_slave_link_state

Similar to state notifications.

We allow caller to indicate if the notification should happen now or later,
depending on if he holds rtnl mutex or not. Introduce bond_slave_link_notify
function (similar to bond_slave_state_notify) which is later on called
with rtnl mutex and goes over slaves and executes delayed notification.

Subject: [PATCH 0419/1375] bonding: set inactive flags on release

Be correct and symmetric to enslave and set inactive flags during release.
That gives LAG offload drivers - lower state change listeners - possibility
to do proper cleanup.

Subject: [PATCH 0421/1375] mlxsw: core: Add support for packets received from
 LAG port

Lower layer (pci) has information if the packet is received via LAG port.
If that is the case, it fills up rx_info accordingly. However upper
layer does not care about lag_id/port_index for received packets so
convert it to local_port before passing it up. For that conversion, lag
mapping array is introduced. Upper layer is responsible for setting up
the mapping according to what is set in HW.

From fc50db98ff872372f266695858f87a12eb1b4f05 Mon Sep 17 00:00:00 2001
From: Eli Cohen <eli@mellanox.com>
Date: Tue, 1 Dec 2015 18:03:09 +0200
Subject: [PATCH 0431/1375] net/mlx5_core: Add base sriov support

This patch adds SRIOV base support for mlx5 supported devices. The same
driver is used for both PFs and VFs; VFs are identified by the driver
through the flag MLX5_PCI_DEV_IS_VF added to the pci table entries.
Virtual functions are created as usual through writing a value to the
sriov_numvs sysfs file of the PF device. Upon instantiating VFs, they will
all be probed by the driver on the hypervisor. One can gracefully unbind
them through /sys/bus/pci/drivers/mlx5_core/unbind.

mlx5_wait_for_vf_pages() was added to ensure that when a VF dies without
executing proper teardown, the hypervisor driver waits till all of the
pages that were allocated at the hypervisor to maintain its operation
are returned.

In order for the VF to be operational, the PF needs to call enable_hca
for it. This can be done before the VFs are created through a call to
pci_enable_sriov.

If the there are VFs assigned to a VMs when the driver of the PF is
unloaded, all the VF will experience system error and PF driver unloads
cleanly; in this case pci_disable_sriov is not called and the devices
will show when running lspci. Once the PF driver is reloaded, it will
sync its data structures which maintain state on its VFs.

Subject: [PATCH 0433/1375] net/mlx5: Update access functions to Query/Modify
 vport MAC address

In preparation for SR-IOV we add here an API to enable each e-switch
client (PF/VF) to configure its L2 MAC addresses and for the e-switch
manager (usually the PF) to access them in order to be able to
configure them into the e-switch.
Therefore we now pass vport num parameter to
mlx5_query_nic_vport_context, so PF can access other vports contexts.

preperation for ethernet sriov and l2 table management.

Subject: [PATCH 0435/1375] net/mlx5: Introduce access functions to
 modify/query vport state

In preparation for SR-IOV we add here an API to enable each e-switch
manager (PF) to configure its VFs link states in e-switch

preparation for ethernet sriov.

Subject: [PATCH 0440/1375] net/mlx5: Introducing E-Switch and l2 table

E-Switch is the software entity that represents and manages ConnectX4
inter-HCA ethernet l2 switching.

E-Switch has its own Virtual Ports, each Vport/vNIC/VF can be
connected to the device through a vport of an e-switch.

Each e-switch is managed by one vNIC identified by
HCA_CAP.vport_group_manager (usually it is the PF/vport[0]),
and its main responsibility is to forward each packet to the
right vport.

e-Switch needs to manage its own l2-table and FDB tables.

L2 table is a flow table that is managed by FW, it is needed for
Multi-host (Multi PF) configuration for inter HCA switching between
PFs.

FDB table is a flow table that is totally managed by e-Switch driver,
its main responsibility is to switch packets between e-Swtich internal
vports and uplink vport that belong to the same.

This patch introduces only e-Swtich l2 table management, FDB managemnt
will come later when ethernet SRIOV/VFs will be enabled.

preperation for ethernet sriov and l2 table management.

Subject: [PATCH 0442/1375] net/mlx5: E-Switch, Add SR-IOV (FDB) support

Enabling E-Switch SRIOV for nvfs+1 vports.

Create E-Switch FDB for L2 UC/MC mac steering between VFs/PF and
external vport (Uplink).

FDB contains forwarding rules such as:
	UC MAC0 -> vport0(PF).
	UC MAC1 -> vport1.
	UC MAC2 -> vport2.
	MC MACX -> vport0, vport2, Uplink.
	MC MACY -> vport1, Uplink.

For unmatched traffic FDB has the following default rules:
	Unmached Traffic (src vport != Uplink) -> Uplink.
	Unmached Traffic (src vport == Uplink) -> vport0(PF).

FDB rules population:
Each NIC vport (VF) will notify E-Switch manager of its UC/MC vport
context changes via modify vport context command, which will be
translated to an event that will be handled by E-Switch manager (PF)
which will update FDB table accordingly.

Subject: [PATCH 0444/1375] net/mlx5: E-Switch, Introduce HCA cap and E-Switch
 vport context

E-Switch vport context is unlike NIC vport context, managed by the
E-Switch manager or vport_group_manager and not by the NIC(VF) driver.

The E-Switch manager can access (read/modify) any of its vports
E-Switch context.

Currently E-Switch vport context includes only clietnt and server
vlan insertion and striping data (for later support of VST mode).

Subject: [PATCH 0451/1375] net: ipv6: restrict hop_limit sysctl setting to
 range [1; 255]

Setting a value bigger than 255 resulted in using only the lower eight
bits of that value as it is assigned to the u8 header field. To avoid
this unexpected result, reject such values.

Setting a value of zero is technically possible, but hosts receiving
such a packet have to treat it like hop_limit was set to one, according
to RFC2460. Therefore I don't see a use-case for that.

Setting a route's hop_limit to zero in iproute2 means to use the sysctl
default, which is not the case here: Setting e.g.
net.conf.eth0.hop_limit=0 will not make the kernel use
net.conf.all.hop_limit for outgoing packets on eth0. To avoid these
kinds of confusion, reject zero.

Subject: [PATCH 0454/1375] mpls: support for dead routes

Adds support for RTNH_F_DEAD and RTNH_F_LINKDOWN flags on mpls
routes due to link events. Also adds code to ignore dead
routes during route selection.

Unlike ip routes, mpls routes are not deleted when the route goes
dead. This is current mpls behaviour and this patch does not change
that. With this patch however, routes will be marked dead.
dead routes are not notified to userspace (this is consistent with ipv4
routes).

dead routes:
-----------
$ip -f mpls route show
100
    nexthop as to 200 via inet 10.1.1.2  dev swp1
    nexthop as to 700 via inet 10.1.1.6  dev swp2

$ip link set dev swp1 down

$ip link show dev swp1
4: swp1: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN mode
DEFAULT group default qlen 1000
    link/ether 00:02:00:00:00:01 brd ff:ff:ff:ff:ff:ff

$ip -f mpls route show
100
    nexthop as to 200 via inet 10.1.1.2  dev swp1 dead linkdown
    nexthop as to 700 via inet 10.1.1.6  dev swp2

linkdown routes:
----------------
$ip -f mpls route show
100
    nexthop as to 200 via inet 10.1.1.2  dev swp1
    nexthop as to 700 via inet 10.1.1.6  dev swp2

$ip link show dev swp1

Subject: [PATCH 0460/1375] pppox: use standard module auto-loading feature

* Register PF_PPPOX with pppox module rather than with pppoe,
    so that pppoe doesn't get loaded for any PF_PPPOX socket.

  * Register PX_PROTO_* with standard MODULE_ALIAS_NET_PF_PROTO()
    instead of using pppox's own naming scheme.

  * While there, add auto-loading feature for pptp.

Subject: [PATCH 0466/1375] mvneta: implement ethtool autonegotiation control

This patch allows to do
ethtool -s eth0 autoneg off
ethtool -s eth0 autoneg on
to disable or enable autonegotiation at run-time.
Without that functionality, the only way to control the autonegotiation
is to modify the device tree.

This is needed if you plan to use the same kernel with
different ethernet switches, the ones that support the in-band
status and the ones that not.

Subject: [PATCH 0467/1375] tipc: fix node reference count bug

Commit 5405ff6e15f40f2f ("tipc: convert node lock to rwlock")
introduced a bug to the node reference counter handling. When a
message is successfully sent in the function tipc_node_xmit(),
we return directly after releasing the node lock, instead of
continuing and decrementing the node reference counter as we
should do.

This commit fixes this bug.

Subject: [PATCH 0468/1375] stmmac: ipq806x: Return error values instead of
 pointers

Typically we return error pointers when we want to use those
pointers in the non-error case, but this function is just
returning error pointers or NULL for success. Change the style to
plain int to follow normal kernel coding styles.

Some devices or drivers cannot deal with having the same station
address for different virtual interfaces, say as a client to two
virtual AP interfaces. Rather than requiring each driver with a
limitation like that to enforce it, add a hardware flag for it.

Subject: [PATCH 0474/1375] cfg80211: replace ieee80211_ie_split() with an

The function is a very simple wrapper around another one,
just adds a few default parameters, so replace it with a
static inline instead of using EXPORT_SYMBOL, reducing
the module size slightly.

This indicates a driver key selection issue, but even then there's

the priv pointer from it -- people debugging will only have a single

This really should never happen except very early in the process

more debugging in the driver and this string isn't useful. Remove
it and save some size (when it's even compiled in.)

 usage with net-detect

In this attribute's documentation, it was not clear whether the delay
started counting when WoWLAN net-detect was enabled or when the system
was suspended.  The correct answer is that it starts when the system
suspends (which is when, in practice, the scan is scheduled).  Clarify
that in the nl80211.h documentation.

Subject: [PATCH 0480/1375] mac80211: allow the driver to send EOSP when needed

This can happen when the driver needs to send less frames
than expected and then needs to close the SP.
Mac80211 still needs to set the more_data properly based
on its buffer state (ps_tx_buffer and buffered frames on
other TIDs).
To that end, refactor the code that delivers frames upon
uAPSD trigger frames to be able to get only the more_data
bit without actually delivering those frames in case the
driver is just asking to set a NDP with EOSP and MORE_DATA
bit properly set.

Subject: [PATCH 0481/1375] mac80211: add atomic uploaded keys iterator

add ieee80211_iter_keys_rcu() to iterate over uploaded
keys in atomic context (when rcu is locked)

The station removal code removes the keys only after
calling synchronize_net(), so it's not safe to iterate
the keys at this point (and postponing the actual key
deletion with call_rcu() might result in some
badly-ordered ops calls).

Add a flag to indicate a station is being removed,
and skip the configured keys if it's set.

We had another change to fix this in mac80211, but the hwsim
"hardware" scan should also be fixed. Obviously this one isn't
important since it's not real hardware, but we'd better be
consistent.

Implement new functionality for aborting an ongoing scan.

Add NL80211_CMD_ABORT_SCAN to the nl80211 interface. After
aborting the scan, driver shall provide the scan status by
calling cfg80211_scan_done().

Subject: [PATCH 0489/1375] cfg80211: handle add_station auth/assoc flag quirks

When a new station is added to AP/GO interfaces the default behaviour
is for it to be added authenticated and associated, due to backwards
compatibility. To prevent that, the driver must be able to do that
(setting the NL80211_FEATURE_FULL_AP_CLIENT_STATE feature flag) and
userspace must set the flag mask to auth|assoc and clear the set.

Handle this quirk in the API entirely in nl80211, and always push the
full flags to the drivers. NL80211_FEATURE_FULL_AP_CLIENT_STATE is
still required for userspace to be allowed to set the mask including
those bits, but after checking that add both flags to the mask and
set in case userspace didn't set them otherwise.

This obsoletes the mac80211 code handling this difference, no other
driver is currently using these flags.

If a mgmt-tx operation is aborted before it runs, the wrong
cookie is reported back to userspace, and the ack_skb gets
leaked since the frame is freed directly instead of freeing
it using ieee80211_free_txskb(). Fix that.

Subject: [PATCH 0496/1375] mac80211: simplify ack_skb handling

Since the cookie is assigned inside ieee80211_make_ack_skb()
now, we no longer need to return the ack_skb as the cookie
and can simplify the function's return and the callers. Also
rename it to ieee80211_attach_ack_skb() to more accurately
reflect its purpose.

Subject: [PATCH 0497/1375] mac80211_hwsim: delay hardware remain-on-channel
 start

Typically drivers that implement hardware remain-on-channel will
have to wait for scheduling constraints, so make hwsim also wait
a little bit (only 20ms) before actually starting the operation.

Subject: [PATCH 0498/1375] mac80211: rewrite remain-on-channel logic

Jouni found a bug in the remain-on-channel logic: when a short item
is queued, a long item is combined with it extending the original
one, and then the long item is deleted, the timeout doesn't go back
to the short one, and the short item ends up taking a long time. In
this case, this showed as blocking scan when running two test cases
back to back - the scan from the second was delayed even though all
the remain-on-channel items should long have been gone.

Fixing this with the current data structures turns out to be a bit
complicated, we just remove the long item from the dependents list
right now and don't recalculate the timeouts.

There's a somewhat similar bug where we delete the short item and
all the dependents go with it; to fix this we'd have to move them
from the dependents to the real list.

Instead of trying to do that, rewrite the code to not have all this
complexity in the data structures: use a single list and allow more
than one entry in it being marked as started. This makes the code a
bit more complex, the worker needs to understand that it might need
to just remove one of the started items, while keeping the device
off-channel, but that's not more complicated than the nested data
structures.

This then fixes both issues described, and makes it easier to also
limit the overall off-channel time when combining.

TODO: as before, with hardware remain-on-channel, deleting an item
after combining results in cancelling them all - we can keep track
of the time elapsed and only cancel after that to fix this.

While it was possible to create an IBSS with 80+80 MHz channel, joining
such an IBSS resulted in falling back to 20 MHz channel with VHT
disabled due to a missing switch case for 80+80.

Subject: [PATCH 0504/1375] mac80211: reject zero cookie in mgmt-tx/roc cancel

When cancelling, you can cancel "any" (first in list) mgmt-tx
or remain-on-channel operation by using the value 0 for the
cookie along with the *opposite* operation, i.e.
 * cancel the first mgmt-tx by cancelling roc with 0 cookie
 * cancel the first roc by cancelling mgmt-tx with 0 cookie

This isn't really that bad since userspace should only pass
cookies that we gave it, but could lead to hard-to-debug
issues so better prevent it and reject zero values since we
never hand those out.

Subject: [PATCH 0505/1375] mac80211_hwsim: check txrate for NULL

If the rate control algorithm messed up then the txrate pointer
here could be NULL - WARN and drop the packet from monitoring.

Subject: [PATCH 0506/1375] mac80211_hwsim: check ATTR_FREQ for wmediumd
 (netlink) packets

If a packet is received from netlink with the frequency value set it is
checked against the current radio's frequency and discarded if different.
The frequency is also checked against data2->tmp_chan to support the "hw"
off-channel/scan case.

Subject: [PATCH 0507/1375] net:hns: Add support of Hip06 SoC to the Hislicon
 Network Subsystem

This patchset adds support of Hisilicon Hip06 SoC to the existing HNS
ethernet driver.

The changes in the driver are mainly due to changes in the DMA
descriptor provided by the Hip06 ethernet hardware. These changes
need to co-exist with already present Hip05 DMA descriptor and its
operating functions. The decision to choose the correct type of DMA
descriptor is taken dynamically depending upon the version of the
hardware (i.e. V1/hip05 or V2/hip06, see already existing
hisilicon-hns-nic.txt binding file for detailed description). other
changes includes in SBM, DSAF and PPE modules as well. Changes
affecting the driver related to the newly added ethernet hardware
features in Hip06 would be added as separate patch over this and
subsequent patches.

Subject: [PATCH 0508/1375] net:hns: Add Hip06 "RSS(Receive Side Scaling)"
 support to HNS Driver

This patch adds the support of "RSS (Receive Side Scaling)" feature
provided by the Hip06 ethernet hardware to the HNS ethernet
driver.

This feature helps in distributing the different flows (mapped as
hash by hardware using Toeplitz Hash) to different Queues asssociated
with the processor cores. The mapping of flow-hash values to the
different queues is stored in indirection table (which is per Packet-
parse-Engine/PPE). This patch also provides the changes to re-program
the (flow-hash<->Qid) mapping using the ethtool.

Subject: [PATCH 0509/1375] net:hns: Add Hip06 "TSO(TCP Segment Offload)"
 support HNS Driver

This patch adds the support of "TSO (TCP Segment Offload)" feature
provided by the Hip06 ethernet hardware to the HNS ethernet
driver.

Enabling this feature would help offload the TCP Segmentation
process to the Hip06 ethernet hardware. This eventually would help
in saving precious cpu cycles.

Subject: [PATCH 0512/1375] net: qmi_wwan: MDM9x30 specific power management
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MDM9x30 based modems appear to go into a deeper sleep when
suspended without "Remote Wakeup" enabled.  The QMI interface
will not respond unless a "set DTR" control request is sent
on resume. The effect is similar to a QMI_CTL SYNC request,
resetting (some of) the firmware state.

We allow userspace sessions to span multiple character device
open/close sequences.  This means that userspace can depend
on firmware state while both the netdev and the character
device are closed.  We have disabled "needs_remote_wakeup" at
this point to allow devices without remote wakeup support to
be auto-suspended.

To make sure the MDM9x30 keeps firmware state, we need to
keep "needs_remote_wakeup" always set. We also need to
issue a "set DTR" request to enable the QMI interface.

Subject: [PATCH 0515/1375] net: qmi_wwan: support "raw IP" mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

QMI wwan devices have traditionally emulated ethernet devices
by default. But they have always had the capability of operating
without any L2 header at all, transmitting and receiving "raw"
IP packets over the USB link.  This firmware feature used to be
configurable through the QMI management protocol.

Traditionally there was no way to verify the firmware mode
without attempting to change it.  And the firmware would often
disallow changes anyway, i.e. due to a session already being
established.  In some cases, this could be a hidden firmware
internal session, completely outside host control.  For these
reasons, sticking with the "well known" default mode was safest.

But newer generations of QMI hardware and firmware have moved
towards defaulting to "raw IP" mode instead, followed by an
increasing number of bugs in the already buggy "802.3" firmware
implementation. At the same time, the QMI management protocol
gained the ability to detect the current mode.  This has enabled
the userspace QMI management application to verify the current
firmware mode without trying to modify it.

Following this development, the latest QMI hardware and firmware
(the MDM9x30 generation) has dropped support for "802.3" mode
entirely. Support for "raw IP" framing in the driver is therefore
necessary for these devices, and to a certain degree to work
around problems with the previous generation,

This patch adds support for "raw IP" framing for QMI devices,
changing the netdev from an ethernet device to an ARPHRD_NONE
p-t-p device when "raw IP" framing is enabled.

The firmware setup is fully delegated to the QMI userspace
management application, through simple tunneling of the QMI
protocol. The driver will therefore not know which mode has been
"negotiated" between firmware and userspace. Allowing userspace
to inform the driver of the result through a sysfs switch is
considered a better alternative than to change the well established
clean delegation of firmware management to userspace.

+
+		The netdev will change to reflect the link framing

+		without any L2 header over the USB link.
+
+		Userspace is in full control of firmware configuration

+		is responsible for coordination of driver and firmware
+		link framing mode, changing this setting to 'Y' if the
+		firmware is configured for 'raw-ip' mode.

Subject: [PATCH 0518/1375] WAN: HDLC: Detach protocol before unregistering
 device

The current code first unregisters the device, and then detaches the
protocol from it. This should be performed the other way around, since
the detach may try to use state which has been freed by the
unregister. Swap the order, so that we first detach and then remove the
netdev.

Subject: [PATCH 0519/1375] WAN: HDLC: Call notifiers before and after changing
 device type

An HDLC device can change type when the protocol driver is changed.
Calling the notifier change allows potential users of the interface
know about this planned change, and even block it. After the change
has occurred, send a second notification to users can evaluate the new
device type etc.

Subject: [PATCH 0523/1375] sfc: check warm_boot_count after other functions
 have been reset

A change in MCFW behaviour means that the net driver must update its record
of the warm_boot_count by reading it from the ER_DZ_BIU_MC_SFT_STATUS
register.

On v4.6.x MCFW the global boot count was incremented when some functions
needed to be reset to enable multicast chaining, so all functions saw the
same value.  In that case, the driver needed to increment its
warm_boot_count when other functions were reset, to avoid noticing it later
and then trying to reset itself to recover unnecessarily.

With v4.7+ MCFW, the boot count in firmware doesn't change as that is
unnecessary since the PFs that have been reset will each receive an MC
reboot notification.  In that case, the driver re-reads the unchanged
value.

Subject: [PATCH 0525/1375] bnx2x: drop redundant error message about
 allocation failure

alloc_pages() already prints a warning when it fails. No need to emit
another message. Certainly not at KERN_ERR level, because it is no big
deal if this GFP_ATOMIC allocation fails occasionally.

Subject: [PATCH 0526/1375] bnx2x: change FW GRO error message to WARN_ONCE

It's supposed to be impossible for TPA to give us anything else
than IPv4 or IPv6 here. But in case there is a way to reach this error
by some strange received frames, we don't want to flood the kernel log.
WARN_ONCE is better for this purpose.

Subject: [PATCH 0527/1375] bnx2x: simplify distinction between port and func
 stats

The 'flags' field in bnx2x_stats_arr[] serves only one purpose - to tell
us if the statistic is a per-port stat and thus should not be shown for
virtual functions. It's strange that the field can have three different
values. A boolean will do just fine.

Also remove IS_FUNC_STAT(). It was used only once and it's in fact just
a negation of IS_PORT_STAT().

Don't change netdev hw_features later in fm10k_probe, instead set all
values inside fm10k_alloc_netdev. To do so, we need to know the MAC type
(whether it is PF or VF) in order to determine what to do. This helps
ensure that all logic regarding features is co-located.

Subject: [PATCH 0531/1375] fm10k: reset max_queues on init_hw_vf failure

VF drivers must detect how many queues are available. Previously, the
driver assumed that each VF has at minimum 1 queue. This assumption is
incorrect, since it is possible that the PF has not yet assigned the
queues to the VF by the time the VF checks. To resolve this, we added a
check first to ensure that the first queue is infact owned by the VF at
init_hw_vf time. However, the code flow did not reset hw->mac.max_queues
to 0. In some cases, such as during reinit flows, we call init_hw_vf
without clearing the previous value of hw->mac.max_queues. Due to this,
when init_hw_vf errors out, if its error code is not properly handled
the VF driver may still believe it has queues which no longer belong to
it. Fix this by clearing the hw->mac.max_queues on exit due to errors.

Subject: [PATCH 0532/1375] fm10k: always check init_hw for errors

A recent change modified init_hw in some flows the function may fail on
VF devices. For example, if a VF doesn't yet own its own queues.
However, many callers of init_hw didn't bother to check the error code.
Other callers checked but only displayed diagnostic messages without
actually handling the consequences.

Fix this by (a) always returning and preventing the netdevice from going
up, and (b) printing the diagnostic in every flow for consistency. This
should resolve an issue where VF drivers would attempt to come up
before the PF has finished assigning queues.

In addition, change the dmesg output to explicitly show the actual
function that failed, instead of combining reset_hw and init_hw into a
single check, to help for future debugging.

Fixes: 1d568b0f6424 ("fm10k: do not assume VF always has 1 queue")

Subject: [PATCH 0533/1375] fm10k: reinitialize queuing scheme after calling
 init_hw

The init_hw function may fail, and in the case of VFs, it might change
the number of maximum queues available. Thus, for every flow which
checks init_hw, we need to ensure that we clear the queue scheme before,
and initialize it after. The fm10k_io_slot_reset path will end up
triggering a reset so fm10k_reinit needs this change. The
fm10k_io_error_detected and fm10k_io_resume also need to properly clear
and reinitialize the queue scheme.

A previous bug was uncovered by addition of a debug stat to indicate the
actual number of DWORDS we pulled from the mbmem. It turned out this was
not the same as the tx_dwords counter. While the previous bug fix should
have corrected this in all cases, add some debug stats that count the
number of DWORDs pushed or pulled from the mbmem. A future debugger may
take advantage of this statistic for debugging purposes. Since we're
modifying fm10k_mbx.h, update the copyright year as well.

Subject: [PATCH 0537/1375] fm10k: rename mbx_tx_oversized statistic to
 mbx_tx_dropped

Originally this statistic was renamed because the method of dropping was
called "drop_oversized_messages", but this logic has changed much, and
this counter does actually represent messages which we failed to
transmit for a number of reasons. Rename the counter back to tx_dropped
since this is when it will increment, and it is less confusing.

Subject: [PATCH 0538/1375] fm10k: Add support for ITR scaling based on PCIe
 link speed

The Intel Ethernet Switch FM10000 Host Interface interrupt throttle
timers are based on the PCIe link speed. Because of this, the value
being programmed into the ITR registers must be scaled accordingly.

For the PF, this is as simple as reading the PCIe link speed and storing
the result. However, in the case of SR-IOV, the VF's interrupt throttle
timers are based on the link speed of the PF. However, the VF is unable
to get the link speed information from its configuration space, so the
PF must inform it of what scale to use.

Rather than pass this scale via mailbox message, take advantage of
unused bits in the TDLEN register to pass the scale. It is the
responsibility of the PF to program this for the VF while setting up the
VF queues and the responsibility of the VF to get the information
accordingly. This is preferable because it allows the VF to set up the
interrupts properly during initialization and matches how the MAC
address is passed in the TDBAL/TDBAH registers.

Since we're modifying fm10k_type.h, we may as well also update the
copyright year.

the check is, and reduces the line length to something more reasonable
in a few places.

Subject: [PATCH 0540/1375] fm10k: Update adaptive ITR algorithm

The existing adaptive ITR algorithm is overly restrictive. It throttles
incorrectly for various traffic rates, and does not produce good
performance. The algorithm now allows for more interrupts per second,
and does some calculation to help improve for smaller packet loads. In
addition, take into account the new itr_scale from the hardware which
indicates how much to scale due to PCIe link speed.

Subject: [PATCH 0542/1375] fm10k: change default Tx ITR to 25usec

The current default ITR for Tx is overly restrictive. Using a simple
netperf TCP_STREAM test, we top out at about 10Gb/s for a single thread
when running using 1500 byte frames. By reducing the ITR value to 25usec
(up to 40K interrupts a second from 10K), we are able to achieve 36Gb/s
for a single thread TCP stream test.

This reverts commit 8fe269991aece394a7ed274f525d96c73f94109a.
The case where VXLAN is a module and i40e driver is inbuilt
will not be handled properly with this change since i40e
will have an undefined symbol vxlan_get_rx_port in it.

The notifier calls were thrown in as a last-minute fix for an
imagined "this device could be part of a bridge" problem. That
revealed a certain lack of locking.  Not to mention testing...

Avoid this splat:

Subject: [PATCH 0550/1375] net/mlx4_core: Support mirroring VF DMFS rules on
 both ports

Under HA mode, steering rules set by VFs should be mirrored on both
ports of the device so packets will be accepted no matter on which
port they arrived.

Since getting into HA mode is done dynamically when the user bonds mlx4
Ethernet netdevs, we keep hold of the VF DMFS rule mbox with the port
value flipped (1->2,2->1) and execute the mirroring when getting into
HA mode. Later, when going out of HA mode, we unset the mirrored rules.
In that context note that mirrored rules cannot be removed explicitly.

Subject: [PATCH 0551/1375] net/mlx4_core: Keep VLAN/MAC tables mirrored in
 multifunc HA mode

Due to HW limitations, indexes to MAC and VLAN tables are always taken
from the table of the actual port. So, if a resource holds an index to
a table, it may refer to different values during the lifetime of the
resource,  unless the tables are mirrored. Also, even when
driver is not in HA mode the policy of allocating an index to these
tables is such to make sure, as much as possible, that when the time
comes the mirroring will be successful. This means that in multifunction
mode the allocation of a free index in a port's table tries to make sure
that the same index in the other's port table is also free.

Subject: [PATCH 0552/1375] IB/mlx4: Use the VF base-port when demuxing mad
 from wire

Under HA mode, it's possible that the VF registered its GID
(and expects to get mads through the PV scheme) on a port which is
different from the one this mad arrived on, due to HA fail over.

Therefore, if the gid is not matched on the port that the packet arrived
on, check for a match on the other port if HA mode is active -- and if a
match is found on the other port, continue processing the mad using that
other port.

Date: Sun, 6 Dec 2015 18:07:43 +0200
Subject: [PATCH 0553/1375] net/mlx4_core: Support the HA mode for SRIOV VFs
 too

When the mlx4 driver runs in HA mode, and all VFs are single ported
ones, we make their single port Highly-Available.

This is done by taking advantage of the HA mode properties (following
bonding changes with programming the port V2P map, etc) and adding
the missing parts which are unique to SRIOV such as mirroring VF
steering rules on both ports.

Due to limits on the MAC and VLAN table this mode is enabled only when
number of total VFs is under 64.

Subject: [PATCH 0554/1375] net: cdc_ncm: add "ndp_to_end" sysfs attribute
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adding a writable sysfs attribute for the "NDP to end"
quirk flag.

This makes it easier for end users to test new devices for
this firmware bug.  We've been lucky so far, but we should
not depend on reporters capable of rebuilding the driver.

Device tree properties for a phy device are expected to be in the phy
node. The current code for the DP83867 also tries to look in the
parent node. The devices binding documentation does not mention this,
no current device tree file makes use of this, and it is not behaviour
we want. So remove looking in the parent device.

Subject: [PATCH 0556/1375] core: enable more fine-grained datagram reception
 control

The __skb_recv_datagram routine in core/ datagram.c provides a general
skb reception factility supposed to be utilized by protocol modules
providing datagram sockets. It encompasses both the actual recvmsg code
and a surrounding 'sleep until data is available' loop. This is
inconvenient if a protocol module has to use additional locking in order
to maintain some per-socket state the generic datagram socket code is
unaware of (as the af_unix code does). The patch below moves the recvmsg
proper code into a new __skb_try_recv_datagram routine which doesn't
sleep and renames wait_for_more_packets to
__skb_wait_for_more_packets, both routines being exported interfaces. The
original __skb_recv_datagram routine is reimplemented on top of these
two functions such that its user-visible behaviour remains unchanged.

Subject: [PATCH 0557/1375] af_unix: fix unix_dgram_recvmsg entry locking

The current unix_dgram_recvsmg code acquires the u->readlock mutex in
order to protect access to the peek offset prior to calling
__skb_recv_datagram for actually receiving data. This implies that a
blocking reader will go to sleep with this mutex held if there's
presently no data to return to userspace. Two non-desirable side effects
of this are that a later non-blocking read call on the same socket will
block on the ->readlock mutex until the earlier blocking call releases it
(or the readers is interrupted) and that later blocking read calls
will wait longer than the effective socket read timeout says they
should: The timeout will only start 'ticking' once such a reader hits
the schedule_timeout in wait_for_more_packets (core.c) while the time it
already had to wait until it could acquire the mutex is unaccounted for.

The patch avoids both by using the __skb_try_recv_datagram and
__skb_wait_for_more packets functions created by the first patch to
implement a unix_dgram_recvmsg read loop which releases the readlock
mutex prior to going to sleep and reacquires it as needed
afterwards. Non-blocking readers will thus immediately return with
-EAGAIN if there's no data available regardless of any concurrent
blocking readers and all blocking readers will end up sleeping via
schedule_timeout, thus honouring the configured socket receive timeout.

 interface is down

There is no reason to keep a reference when the interface is down,
since we are not really doing anything.  The reference is only needed
when the mac80211 start op (or a hw restart) is running, to prevent
going into runtime or system supend in the meantime.  This will allow
us to support runtime PM when the interface is down (in another
patch).

Subject: [PATCH 0559/1375] mac80211: handle HW ROC expired properly

In case of HW ROC, when the driver reports that the ROC expired,
it is not sufficient to purge the ROCs based on the remaining
time, as it possible that the device finished the ROC session
before the actual requested duration.

To handle such cases, in case of ROC expired notification from
the driver, complete all the ROCs which are marked with hw_begun,
regardless of the remaining duration.

Subject: [PATCH 0560/1375] net: thunderx: nicvf_queues: nivc_*_intr: remove
 duplication

The same switch-case repeates for nivc_*_intr functions.
In this patch it is moved to a helper nicvf_int_type_to_mask().

By the way:
 - Unneeded write to NICVF register dropped if int_type is unknown.
 - netdev_dbg() is used instead of netdev_err().

Subject: [PATCH 0561/1375] net, thunderx: Remove unnecessary rcv buffer start
 address management

Since we have moved on to using allocated pages to carve receive
buffers instead of netdev_alloc_skb() there is no need to store
any pointers for later retrieval. Earlier we had to store
skb and skb->data pointers which later are used to handover
received packet to network stack.

This will avoid an unnecessary cache miss as well.

Subject: [PATCH 0569/1375] ath9k: Simplify and fix eeprom endianness swapping

The three eeprom implementations had quite some duplicate code when it
came to endianness swapping.
Additionally there was a bug in eeprom_4k and eeprom_9287 which
prevented the endianness swapping from working correctly, because the
swapping code was guarded within an "if (!ath9k_hw_use_flash(ah))". In
eeprom_def this check did not exist, so it seems that eeprom_def was the
only implementation where endianness swapping worked.

This patch takes the duplicate code and moves it from eeprom_* to
eeprom.c. The new code is derived from eeprom_def, while taking into
account the specifics from the other implementations.

Subject: [PATCH 0570/1375] ath6kl: Don't print error message when recv is
 canceled

An error message ath6kl_htc_rxmsg_pending_handler isn't appropate for when
the error is ECANCELED. This could be the result of a perfectly appropriate
RX cancel due to shutdown or suspend. This allows the right cleanup to
continue, but without an alarming error message in this particular case.

Subject: [PATCH 0572/1375] wil6210: prevent external wmi commands during
 suspend flow

In __wmi_send we check if fw is ready at the beginning of the function.
While we wait for the completion of the previous command, system suspend
can be invoked and reset the HW, causing __wmi_send to read from HW
registers while it is not ready.
Taking the wmi_mutex in the reset flow when setting the FW ready bit
to zero will prevent the above race condition.

While mac80211 using null frames when connection polling,
we should queue this frames while NOA could be there, and
AP, P2P_GO could be not present.

Without this patch, with no traffic we often saw disconnections
while we try to send nullfunc when AP/GO wasn't present.

bb_{set|clr}() as well as bb_read() -- just expand them inline, thus
saving more LoCs...

Subject: [PATCH 0589/1375] Revert "Merge branch 'vsock-virtio'"

This reverts commit 0d76d6e8b2507983a2cae4c09880798079007421 and merge
commit c402293bd76fbc93e52ef8c0947ab81eea3ae019, reversing changes made
to c89359a42e2a49656451569c382eed63e781153c.

The virtio-vsock device specification is not finalized yet.  Michael
Tsirkin voiced concerned about merging this code when the hardware
interface (and possibly the userspace interface) could still change.

From 297dbde19cf6a0ccb6fd4396c6220a5912ed61e8 Mon Sep 17 00:00:00 2001
From: Tejun Heo <tj@kernel.org>
Date: Mon, 7 Dec 2015 17:38:51 -0500
Subject: [PATCH 0590/1375] netprio_cgroup: limit the maximum css->id to
 USHRT_MAX

netprio builds per-netdev contiguous priomap array which is indexed by
css->id.  The array is allocated using kzalloc() effectively limiting
the maximum ID supported to some thousand range.  This patch caps the
maximum supported css->id to USHRT_MAX which should be way above what
is actually useable.

This allows reducing sock->sk_cgrp_prioidx to u16 from u32.  The freed
up part will be used to overload the cgroup related fields.
sock->sk_cgrp_prioidx's position is swapped with sk_mark so that the
two cgroup related fields are adjacent.

Subject: [PATCH 0591/1375] net: wrap sock->sk_cgrp_prioidx and ->sk_classid
 inside a struct

Introduce sock->sk_cgrp_data which is a struct sock_cgroup_data.
->sk_cgroup_prioidx and ->sk_classid are moved into it.  The struct
and its accessors are defined in cgroup-defs.h.  This is to prepare
for overloading the fields with a cgroup pointer.

This patch mostly performs equivalent conversions but the followings
are noteworthy.

* Equality test before updating classid is removed from
  sock_update_classid().  This shouldn't make any noticeable
  difference and a similar test will be implemented on the helper side
  later.

* sock_update_netprioidx() now takes struct sock_cgroup_data and can
  be moved to netprio_cgroup.h without causing include dependency
  loop.  Moved.

* The dummy version of sock_update_netprioidx() converted to a static
  inline function while at it.

Subject: [PATCH 0592/1375] sock, cgroup: add sock->sk_cgroup

In cgroup v1, dealing with cgroup membership was difficult because the
number of membership associations was unbound.  As a result, cgroup v1
grew several controllers whose primary purpose is either tagging
membership or pull in configuration knobs from other subsystems so
that cgroup membership test can be avoided.

net_cls and net_prio controllers are examples of the latter.  They
allow configuring network-specific attributes from cgroup side so that
network subsystem can avoid testing cgroup membership; unfortunately,
these are not only cumbersome but also problematic.

Both net_cls and net_prio aren't properly hierarchical.  Both inherit
configuration from the parent on creation but there's no interaction
afterwards.  An ancestor doesn't restrict the behavior in its subtree
in anyway and configuration changes aren't propagated downwards.
Especially when combined with cgroup delegation, this is problematic
because delegatees can mess up whatever network configuration
implemented at the system level.  net_prio would allow the delegatees
to set whatever priority value regardless of CAP_NET_ADMIN and net_cls
the same for classid.

While it is possible to solve these issues from controller side by
implementing hierarchical allowable ranges in both controllers, it
would involve quite a bit of complexity in the controllers and further
obfuscate network configuration as it becomes even more difficult to
tell what's actually being configured looking from the network side.
While not much can be done for v1 at this point, as membership
handling is sane on cgroup v2, it'd be better to make cgroup matching
behave like other network matches and classifiers than introducing
further complications.

In preparation, this patch updates sock->sk_cgrp_data handling so that
it points to the v2 cgroup that sock was created in until either
net_prio or net_cls is used.  Once either of the two is used,
sock->sk_cgrp_data reverts to its previous role of carrying prioidx
and classid.  This is to avoid adding yet another cgroup related field
to struct sock.

As the mode switching can happen at most once per boot, the switching
mechanism is aimed at lowering hot path overhead.  It may leak a
finite, likely small, number of cgroup refs and report spurious
prioidx or classid on switching; however, dynamic updates of prioidx
and classid have always been racy and lossy - socks between creation
and fd installation are never updated, config changes don't update
existing sockets at all, and prioidx may index with dead and recycled
cgroup IDs.  Non-critical inaccuracies from small race windows won't
make any noticeable difference.

This patch doesn't make use of the pointer yet.  The following patch
will implement netfilter match for cgroup2 membership.

v2: Use sock_cgroup_data to avoid inflating struct sock w/ another
    cgroup specific field.

v3: Add comments explaining why sock_data_prioidx() and
    sock_data_classid() use different fallback values.

Subject: [PATCH 0597/1375] cxgb4: prevent simultaneous execution of
 service_ofldq()

Change mutual exclusion mechanism to prevent multiple threads of
execution from running in service_ofldq() at the same time.  The old
mechanism used an implicit guard on the down-call path and none on the
restart path and wasn't working. This checking makes the mechanism
explicit and is much easier to understand as a result.

Subject: [PATCH 0601/1375] rhashtable: Remove unnecessary wmb for future_tbl

The patch 9497df88ab5567daa001829051c5f87161a81ff0 ("rhashtable:
Fix reader/rehash race") added a pair of barriers.  In fact the
wmb is superfluous because every subsequent write to the old or
new hash table uses rcu_assign_pointer, which itself carriers a
full barrier prior to the assignment.

Therefore we may remove the explicit wmb.

Subject: [PATCH 0602/1375] bnx2x: avoid soft lockup in bnx2x_poll()

Under heavy TX load, bnx2x_poll() can loop forever and trigger
soft lockup bugs.

A napi poll handler must yield after one TX completion round,
risk of livelock is too high otherwise.

Bug is very easy to trigger using a debug build, and udp flood, because
of added cpu cycles in TX completion, and we do not receive enough
packets to break the loop.

Subject: [PATCH 0605/1375] netfilter: nf_tables: extend tracing infrastructure

nft monitor mode can then decode and display this trace data.

Parts of LL/Network/Transport headers are provided as separate
attributes.

Otherwise, printing IP address data becomes virtually impossible
for userspace since in the case of the netdev family we really don't
want userspace to have to know all the possible link layer types
and/or sizes just to display/print an ip address.

We also don't want userspace to have to follow ipv6 header chains
to get the s/dport info, the kernel already did this work for us.

To avoid bloating nft_do_chain all data required for tracing is
encapsulated in nft_traceinfo.

The structure is initialized unconditionally(!) for each nft_do_chain
invocation.

This unconditionall call will be moved under a static key in a
followup patch.

With lots of help from Patrick McHardy and Pablo Neira.

From e639f7ab079b5256660018511d87aa34b54f1a9d Mon Sep 17 00:00:00 2001
From: Florian Westphal <fw@strlen.de>
Date: Sat, 28 Nov 2015 21:53:05 +0100
Subject: [PATCH 0606/1375] netfilter: nf_tables: wrap tracing with a static
 key

Only needed when meta nftrace rule(s) were added.
The assumption is that no such rules are active, so the call to
nft_trace_init is "never" needed.

When nftrace rules are active, we always call the nft_trace_* functions,
but will only send netlink messages when all of the following are true:

 - traceinfo structure was initialised
 - skb->nf_trace == 1
 - at least one subscriber to trace group.

Adding an extra conditional
(static_branch ... && skb->nf_trace)
	nft_trace_init( ..)

Is possible but results in a larger nft_do_chain footprint.

Subject: [PATCH 0607/1375] netfilter: ipv6: nf_defrag: fix NULL deref panic

Valdis reports NULL deref in nf_ct_frag6_gather.
Problem is bogus use of skb_queue_walk() -- we miss first skb in the list
since we start with head->next instead of head.

In case the element we're looking for was head->next we won't find
a result and then trip over NULL iter.

(defrag uses plain NULL-terminated list rather than one terminated by
 head-of-list-pointer, which is what skb_queue_walk expects).

Subject: [PATCH 0608/1375] netfilter: nfnetlink_log: Change setter functions
 to be void

Change return type of nfulnl_set_timeout() and nfulnl_set_qthresh() to
be void.

This patch changes the return type of the static methods
nfulnl_set_timeout() and nfulnl_set_qthresh() to be void, as there is no
justification and no need for these methods to return int.

Subject: [PATCH 0610/1375] cgroup: fix sock_cgroup_data initialization on
 earlier compilers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sock_cgroup_data is a struct containing an anonymous union.
sock_cgroup_set_prioidx() and sock_cgroup_set_classid() were
initializing a field inside the anonymous union as follows.

 struct sock_ccgroup_data skcd_buf = { .val = VAL };

While this is fine on more recent compilers, gcc-4.4.7 triggers the
following errors.

 include/linux/cgroup-defs.h: In function ‘sock_cgroup_set_prioidx’:
 include/linux/cgroup-defs.h:619: error: unknown field ‘val’ specified in initializer
 include/linux/cgroup-defs.h:619: warning: missing braces around initializer
 include/linux/cgroup-defs.h:619: warning: (near initialization for ‘skcd_buf.<anonymous>’)

This is because .val belongs to the anonymous union nested inside the
struct but the initializer is missing the nesting.  Fix it by adding
an extra pair of braces.

Subject: [PATCH 0611/1375] Bluetooth: Run page scan updates through
 hdev->req_workqueue

Since Add/Remove Device perform the page scan updates independently
from the HCI command completion we've introduced a potential race when
multiple mgmt commands are queued. Doing the page scan updates through
the req_workqueue ensures that the state changes are performed in a
race-free manner.

At the same time, to make the request helper more widely usable,
extend it to also cover Inquiry Scan changes since those are behind
the same HCI command. This is also reflected in the new name of the
API as well as the work struct name.

From f22525700b2ae34eb97a29a91e2eee902062b484 Mon Sep 17 00:00:00 2001
From: Johan Hedberg <johan.hedberg@intel.com>
Date: Wed, 18 Nov 2015 12:49:20 +0200
Subject: [PATCH 0613/1375] Bluetooth: Move advertising instance management to
 hci_request.c

This paves the way for eventually performing advertising changes
through the hdev->req_workqueue. Some new APIs need to be exposed from
mgmt.c to hci_request.c and vice-versa, but many of them will go away
once hdev->req_workqueue gets used.

From 53c0ba74510c1182786dcd1e3710215467777601 Mon Sep 17 00:00:00 2001
From: Johan Hedberg <johan.hedberg@intel.com>
Date: Sun, 22 Nov 2015 16:43:43 +0300
Subject: [PATCH 0614/1375] Bluetooth: Move connectable changes to
 hdev->req_workqueue

This way the connectable changes are synchronized against each other,
which helps avoid potential races. The connectable mode is also linked
together with LE advertising which makes is more convenient to have it
behind the same workqueue.

Subject: [PATCH 0615/1375] Bluetooth: Perform Class of Device changes through
 hdev->req_workqueue

The Class of Device needs to be changed e.g. for limited discoverable
mode. In preparation of moving the discoverable mode to hci_request.c
and hdev->req_workqueue, move the Class of Device helpers there first.

Subject: [PATCH 0616/1375] Bluetooth: Move discoverable changes to
 hdev->req_workqueue

The discoverable mode is intrinsically linked with the connectable
mode e.g. through sharing the same HCI command (Write Scan Enable) for
BR/EDR. It makes therefore sense to move it to hci_request.c and run
the changes through the same hdev->req_workqueue.

Subject: [PATCH 0620/1375] Bluetooth: Move fast connectable code to
 hci_request.c

We'll soon need this both in hci_request.c and mgmt.c so move it to
hci_request.c as a generic helper.

From 2ff13894cfb877cb3d02d96a8402202f0a6f3efd Mon Sep 17 00:00:00 2001
From: Johan Hedberg <johan.hedberg@intel.com>
Date: Wed, 25 Nov 2015 16:15:44 +0200
Subject: [PATCH 0621/1375] Bluetooth: Perform HCI update for power on
 synchronously

The request to update HCI during power on is always coming either from
hdev->req_workqueue or through an ioctl, so it's safe to use
hci_req_sync for it. This way we also eliminate potential races with
incoming mgmt commands or other actions while powering on.

Part of this refactoring is the splitting of mgmt_powered() into
mgmt_power_on() and __mgmt_power_off() functions. The main reason is
the different requirements as far as hdev locking is concerned, as
highlighted with the __ prefix of the power off API.

Since the power on in the case of clearing the AUTO_OFF flag cannot be
done synchronously in the set_powered mgmt handler, the hci_power_on
work callback is extended to cover this (which also simplifies the
set_powered helper a lot).

This flag just tells us whether hdev->adv_instances is empty or not.
We can equally well use the list_empty() function to get this

Subject: [PATCH 0628/1375] Bluetooth: Clean up advertising initialization in
 powered_update_hci()

The logic in powered_update_hci() to initialize the advertising data &
state is a bit more complicated than it needs to be. It was previously
not doing anything if HCI_LE_ENABLED wasn't set, but this was not
obvious by quickly looking at the code. Now the conditions for the
various actions are more explicit. Another simplification is due to
the fact that __hci_req_schedule_adv_instance() takes care of setting
hdev->cur_adv_instance so there's no need to set it before calling the
function.

Subject: [PATCH 0629/1375] Bluetooth: Clean up current advertising instance
 tracking

We can simplify a lot of code by making sure hdev->cur_adv_instance is
always up-to-date. This allows e.g. the removal of the
get_current_adv_instance() helper function and the special
HCI_ADV_CURRENT value. This patch also makes selecting instance 0x00
explicit in the various calls where advertising instances aren't
enabled, e.g. when HCI_ADVERTISING is set or we've just finished
enabling LE.

Add enter/exit manufaturing methods and refactor existing

Subject: [PATCH 0634/1375] Bluetooth: Use continuous scanning when creating LE
 connections

All LE connections are now triggered through a preceding passive scan
and waiting for a connectable advertising report. This means we've got
the best possible guarantee that the device is within range and should
be able to request the controller to perform continuous scanning. This
way we minimize the risk that we miss out on any advertising packets.

Subject: [PATCH 0635/1375] Bluetooth: Don't treat connection timeout as a
 failure

When we're doing background scanning and connection attempts it's
possible we timeout trying to connect and go back to scanning again.
The timeout triggers a HCI_LE_Create_Connection_Cancel which will
trigger a Connection Complete with "Unknown Connection Identifier"
error status. Since we go back to scanning this isn't really a failure
and shouldn't be presented as such to user space through mgmt.

The exception to this is if the connection attempt was due to an
explicit request on an L2CAP socket (indicated by
params->explicit_connect being true). Since the socket will get an
error it's consistent to also notify the failure on mgmt in this case.

Subject: [PATCH 0636/1375] Bluetooth: Fix locking in bt_accept_dequeue after
 disconnection

Fix a crash that may happen when bt_accept_dequeue is run after a
Bluetooth connection has been disconnected. bt_accept_unlink was called
after release_sock, permitting bt_accept_unlink to run twice on the same
socket and cause a NULL pointer dereference.

Subject: [PATCH 0645/1375] 6lowpan: add lowpan dev register helpers

This patch introduces register and unregister functionality for lowpan
interfaces. While register a lowpan interface there are several things
which need to be initialize by the 6lowpan subsystem. Upcoming
functionality need to register/unregister per interface components e.g.
debugfs entry.

Subject: [PATCH 0647/1375] ipv6: add ipv6_addr_prefix_copy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds a static inline function ipv6_addr_prefix_copy which
copies a ipv6 address prefix(argument pfx) into the ipv6 address prefix.
The prefix len is given by plen as bits. This function mainly based on
ipv6_addr_prefix which copies one address prefix from address into a new
ipv6 address destination and zero all other address bits.

The difference is that ipv6_addr_prefix_copy don't get a prefix from an
ipv6 address, it sets a prefix to an ipv6 address with keeping other
address bits. The use case is for context based address compression
inside 6LoWPAN IPHC header which keeping ipv6 prefixes inside a context
table to lookup address-bits without sending them.

This patch reverts 6001d52 ("mac802154: tx: don't allow if down while
sync tx"). This has side effects with stop callback which flush the
transmit workqueue. The stop callback will wait until the workqueue is
flushed and holding the rtnl lock. That means it can happen that the stop
callback waits forever because it try to lock the rtnl mutex which is
already hold by stop callback.

Subject: [PATCH 0651/1375] Bluetooth: Do not filter multicast addresses by
 default

A Linux PC is connected with another device over Bluetooth PAN using a
BNEP interface.

Whenever a packet is tried to be sent over the BNEP interface, the
function "bnep_net_xmit()" in "net/bluetooth/bnep/netdev.c" is called.
This function calls "bnep_net_mc_filter()", which checks (if the
destination address is multicast) if the address is set in a certain
multicast filter (&s->mc_filter). If it is not, then it is not sent out.

This filter is only changed in two other functions, found in
net/bluetooth/bnep/core.c": in "bnep_ctrl_set_mc_filter()", which is
only called if a message of type "BNEP_FILTER_MULTI_ADDR_SET" is
received. Otherwise, it is set in "bnep_add_connection()", where it is
set to a default value which only adds the broadcast address to the
filter:

set_bit(bnep_mc_hash(dev->broadcast), (ulong *) &s->mc_filter);

To sum up, if the BNEP interface does not receive any message of type
"BNEP_FILTER_MULTI_ADDR_SET", it will not send out any messages with
multicast destination addresses except for broadcast.

However, in the BNEP specification (page 27 in
http://grouper.ieee.org/groups/802/15/Bluetooth/BNEP.pdf), it is said
that per default, all multicast addresses should not be filtered, i.e.
the BNEP interface should be able to send packets with any multicast
destination address.

It seems that the default case is wrong: the multicast filter should not
block almost all multicast addresses, but should not filter out any.

This leads to the problem that e.g. Neighbor Solicitation messages sent
with Bluetooth PAN over the BNEP interface to a multicast destination
address other than broadcast are blocked and not sent out.

Therefore, in the default case, we set the mc_filter to ~0LL to not
filter out any multicast addresses.

Content-Transfer-Encoding: 8bit

This driver has been sitting in the linux-zigbee[2] repository for a long
time. We updated it from time to time and made it available via our
github kernel repository. The Linux MAC802.15.4 support has improved a lot
since then. Thanks to all! So it’s finally time to upstream this driver.

The ADF7242 requires an add-on firmware for the automatic IEEE 802.15.4
operating modes. The firmware file is currently made available on the
ADF7242 wiki page here [1]

There is a null ptr check for fws to set bcmc_credit_check, however,
there a lock and unlock on fws should only performed if fwts is
also not null to also avoid a potential null pointer deference.

It's been observed that even if firmware returns an error

This patch changes the command type from async to sync
so that threads waits for command response and return
failure start AP.

Subject: [PATCH 0662/1375] mwifiex: set regulatory info from EEPROM

Driver gets country information from EEPROM during
initialization. We will call regulatory_hint to update
current regulatory domain.
As by default world regulatory domain is selected by
cfg80211, country '00' from EEPROM is ignored.

If device has already received country information from

firmware. We will also set regulatory flags to disable beacon
hints and ignore country IE.

EU is not a valid country in db.txt file. Hence regulatory_hint

use FR for 0x30.

Free skb for received frames with a wrong checksum. This can happen

This fixes a memleak (detected with kmemleak). Originally found while
using monitor mode, but it also appears during managed mode (once the

Subject: [PATCH 0669/1375] iwlegacy: mark il_adjust_beacon_interval as
 noinline

With the new optimized do_div() code, some versions of gcc
produce obviously incorrect code that leads to a link error
in iwlegacy/common.o:

drivers/built-in.o: In function `il_send_rxon_timing':
:(.text+0xa6b4d4): undefined reference to `____ilog2_NaN'
:(.text+0xa6b4f0): undefined reference to `__aeabi_uldivmod'

In a few thousand randconfig builds, I have seen this problem
a couple of times in this file, but never anywhere else in the
kernel, so we can try to work around this in the only file
that shows the behavior, by marking the il_adjust_beacon_interval
function as noinline, which convinces gcc to use the unoptimized
do_div() all the time.

Subject: [PATCH 0676/1375] brcmfmac: no interface combination check for single
 interface

The interface combinations are intended for use-case in which the driver
handles multiple interface concurrently. This means that the combinations
do not need to be checked when there is only a single interface active.

------------------------------------------------------------------------

There are three other place in drivers/net/wireless/brcm80211/brcmfmac/
which have similar code.  The attached patch removes the call to
waitqueue_active() leaving just wake_up() behind.  This fixes the
problem because the call to spin_lock_irqsave() in wake_up() will be an
ACQUIRE operation.

I found this issue when I was looking through the linux source code
for places calling waitqueue_active() before wake_up*(), but without
preceding memory barriers, after sending a patch to fix a similar
issue in drivers/tty/n_tty.c  (Details about the original issue can be
found here: https://lkml.org/lkml/2015/9/28/849).

Subject: [PATCH 0679/1375] brcmfmac: add 43242 device id for LG dongle

Got a hint on IRC that a 43242 dongle for LG smart TV's works with
brcmfmac:

> Hello - I recently got a LG AN-WF500 wireless dongle for LG's SmartTVs.
> From the information I gathered it uses a Broadcom chipset BCM43242.
> The device should have been supported by brcmfmac kernel driver if it used
> USB IDs 0a5c:bd1f.
> My device however identifies itself as "ID 043e:3101 LG Electronics USA, Inc.".
> I then tried adding the USB ID to the driver with
> "echo "043e 3101" > /sys/bus/usb/drivers/brcmfmac/new_id" and it just works.
> The kernel provides the following information.
> [15958.851291] usb 3-1.1.3: new high-speed USB device number 53 using ehci-pci
> [15958.946723] usb 3-1.1.3: New USB device found, idVendor=043e, idProduct=3101
> [15958.946728] usb 3-1.1.3: New USB device strings: Mfr=1, Product=4, SerialNumber=3
> [15958.946731] usb 3-1.1.3: Product: Composite Wireless Adapter

> [15958.946735] usb 3-1.1.3: SerialNumber: 28458

Subject: [PATCH 0682/1375] wlcore/wl12xx: spi: fix oops on firmware load

The maximum chunks used by the function is
(SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE + 1).
The original commands array had space for
(SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE) commands.
When the last chunk is used (len > 4 * WSPI_MAX_CHUNK_SIZE), the last
command is stored outside the bounds of the commands array.

Oops 5 (page fault) is generated during current wl1271 firmware load
attempt:

Subject: [PATCH 0685/1375] ath9k: fix AR_RX_FILTER for ar9462/ar9565 when rx

When rx stopped, AR_RX_FILTER should be cleared, but in
ath9k_hw_setrxfilter(), ATH9K_RX_FILTER_CONTROL_WRAPPER will always
be set for ar9462/ar9565.

Fix this by moving the code in ath9k_hw_setrxfilter() to
ath_calcrxfilter().

Subject: [PATCH 0686/1375] ath9k: feeding entropy in kernel from ADC capture

This patch is derived from
commit 6301566e0b2d ("ath9k: export HW random number generator"),

We evaluated the entropy of the ADC data on QCA9531, QCA9561, QCA955x,
and AR9340, and it has sufficient quality random data (at least 10 bits
and up to 22 bits of min-entropy for a 32-bit value). We conservatively
assume the min-entropy is 10 bits out of 32 bits. Thus, ATH9K_RNG_BUF_SIZE
is set to 320 (u32) i.e., 1.25 kilobytes of data is inserted to fill up
the pool as soon as the entropy counter becomes 896/4096 (set by random.c).
Since ADC was not designed to be a dedicated HW RNG, we do not want to bind
it to /dev/hwrng framework directly. This patch feeds the entropy directly
from the WiFi driver to the input pool. The ADC register output is only
used as a seed for the Linux entropy pool. No conditioning is needed,
since all the conditioning is performed by the pool itself.

Subject: [PATCH 0688/1375] netcp: try to reduce type confusion in descriptors

The netcp driver produces tons of warnings when CONFIG_LPAE is enabled
on ARM:

drivers/net/ethernet/ti/netcp_core.c: In function 'netcp_tx_map_skb':
drivers/net/ethernet/ti/netcp_core.c:1084:13: warning: passing argument 1 of 'set_words' from incompatible pointer type [-Wincompatible-pointer-types]

This is the result of trying to pass a pointer to a dma_addr_t to
a function that expects a u32 pointer to copy that into a DMA descriptor.

Looking at that code in more detail to fix the warnings, I see multiple
related problems:

* The conversion functions are not endian-safe, as the DMA descriptors
  are almost certainly fixed-endian, but the CPU is not.

* On 64-bit machines, passing a pointer through a u32 variable is a
  bug, accessing an indirect pointer as a u32 pointer even more so.

* The handling of epib and psdata mixes native-endian and device-endian
  data.

In this patch, I try to sort out the types for most accesses here,
adding le32_to_cpu/cpu_to_le32 where appropriate, and passing pointers
through two 32-bit words in the descriptor padding, to make it plausible
that the driver does the right thing if compiled for big-endian or
64-bit systems.

Subject: [PATCH 0689/1375] netcp: add more __le32 annotations

The handling of epib and psdata remains a bit unclear in the driver,
as we access the same fields both as CPU-endian and through DMA
from the device.

Sparse warns about this:
ti/netcp_core.c:1147:21: warning: incorrect type in assignment (different base types)
ti/netcp_core.c:1147:21:    expected unsigned int [usertype] *[assigned] epib
ti/netcp_core.c:1147:21:    got restricted __le32 *<noident>

This uses __le32 types in a few places and uses __force where the code
looks fishy. The previous patch should really have produced the correct
behavior, but this second patch is needed to shut up the warnings about
it. Ideally it would be slightly rewritten to not need those casts,
but I don't dare do that without access to the hardware for proper
testing.

Subject: [PATCH 0692/1375] cxgb4: Handle clip return values

Add a warn message when clip table overflows. If clip table isn't
allocated, return from cxgb4_clip_release() to avoid panic.
Disable offload if clip isn't enabled in the hardware.

Subject: [PATCH 0695/1375] net: mvneta: Associate RX queues with each CPU

We enable the percpu interrupt for all the CPU and we just associate a
CPU to a few queue at the neta level. The mapping between the CPUs and
the queues is static. The queues are associated to the CPU module the
number of CPUs. However currently we only use on RX queue for a given
Ethernet port.

Subject: [PATCH 0696/1375] net: mvneta: Add naive RSS support

This patch adds the support for the RSS related ethtool
function. Currently it only uses one entry in the indirection table which
allows associating an mvneta interface to a given CPU.

Subject: [PATCH 0698/1375] Doc: Micrel-ksz90x1.txt: Document deprecated MAC OF

Phy properties are expected to be found in the PHY OF node. However
this Micrel driver also allows them to be placed into the MAC OF node.
This is deprecated. Document it as such, and remove the example using
the deprecated method to prevent people copying it into new device
tree files.

Subject: [PATCH 0702/1375] net/mlx5e: Assign random MAC address if needed

Under SRIOV there might be a case where VFs are loaded
without pre-assigned MAC address. In this case, the VF
will randomize its own MAC.  This will address the case
of administrator not assigning MAC to the VF through
the PF OS APIs and keep udev happy.

From de8575e014685034728396f9d69169428be9cc3d Mon Sep 17 00:00:00 2001
From: Maor Gottlieb <maorg@mellanox.com>
Date: Thu, 10 Dec 2015 17:12:40 +0200
Subject: [PATCH 0704/1375] net/mlx5_core: Add flow steering base data
 structures

Introducing the base data structure and its operations that are
going to represent ConnectX-4 Flow Steering, this data structure
is basically a tree and all Flow steering objects such as
(Flow Table/Flow Group/FTE/etc ..) are represented as fs_node(s).

fs_node is the base object which describes a basic tree node, with the
following extra info:
    type: describes the runtime type of the node (Object).
    lock: lock this node sub-tree.
    ref_count: number of children + current references.
    remove_func: a generic destructor.

fs_node types will be used and explained once the usage is added in the
following patches.

Subject: [PATCH 0705/1375] net/mlx5_core: Add flow steering lookup algorithms

Introduce the flow steering mlx5_flow_namespace (Namespace)
and fs_prio (Flow Steering Priority) tree nodes.

Namespaces are used in order to isolate different usages or types
of steering (for example, downstream patches will add a different
namespaces for the NIC driver and for E-Switch FDB usages).

Flow Steering Priorities are objects that describes priorities
ranges between different flow objects under the same namespace.

Example, entries in priority i are matched before entries
in priority i+1.

This patch adds the following algorithms:

1) Calculate level:
Each flow table has level(the priority between the flow tables).
When we initialize the flow steering tree, we assign range of levels
to each priority, therefore the level for new flow table is
the location within the priority related to the range of the priority.

2) Match between match criteria. This function is used
for searching flow group when new flow rule is added.

3) Match between match values. This function is used
for searching flow table entry  when new flow rule is added.

4) Add essential macros for traversing on a node's children.
E.g. traversing on all the flow table of some priority

Subject: [PATCH 0706/1375] net/mlx5_core: Introduce flow steering API

Introducing the following objects:

mlx5_flow_root_namespace: represent the root of specific flow table
type tree(e.g NIC receive, FDB, etc..)

mlx5_flow_group: define the mask of the flow specification.

fs_fte(flow steering flow table entry): defines the value of the
flow specification.

The following describes the relationships between the tree objects:
root_namespace --> priorities -->namespaces -->
priorities -->flow-tables --> flow-groups -->
flow-entries --> destinations

When we create new object(flow table/flow group/flow table entry), we
call to the FW command and then we add the related sw object to the tree.

When we destroy object, e.g. call to mlx5_destroy_flow_table, we use
the tree node destructor for destroying the FW object and remove the
node from the tree.

Subject: [PATCH 0707/1375] net/mlx5_core: Flow steering tree initialization

Flow steering initialization is based on static tree which
illustrates the flow steering tree when the driver is loaded. The
initialization considers the max supported flow table level of the device,
a minimum of 2 kernel flow tables(vlan and mac) are required to have
kernel flow table functionality.

The tree structures when the driver is loaded:

		root_namespace(receive nic)
			  |
		priority-0 (kernel priority)
			  |
		namespace(kernel namespace)
			  |
		priority-0 (flow tables priority)

In the following patches, When the EN driver will use the flow steering
API, it create two flow tables and their flow groups under
priority-0(flow tables priority).

From 86d722ad2c3bd2f0536b196b7fd67ae2a7e2a492 Mon Sep 17 00:00:00 2001
From: Maor Gottlieb <maorg@mellanox.com>
Date: Thu, 10 Dec 2015 17:12:44 +0200
Subject: [PATCH 0708/1375] net/mlx5: Use flow steering infrastructure for
 mlx5_en

Expose the new flow steering API and remove the old
one.

Few changes are required:

1. The Ethernet flow steering follows the existing implementation, but uses
the new steering API. The old flow steering implementation is removed.

2. Move the E-switch FDB management to use the new API.

3. When driver is loaded call to mlx5_init_fs which initialize
the flow steering tree structure, open namespaces for NIC receive
and for E-switch FDB.

4. Call to mlx5_cleanup_fs when the driver is unloaded.

Subject: [PATCH 0714/1375] ixgbe: Simplify definitions for regidx and bit in
 set_vfta

This patch simplifies the logic for setting the VFTA register by removing
the number of conditional checks needed.  Instead we just use some boolean
logic to generate vfta_delta, and if that is set then we xor the vfta by
that value and write it back.

Subject: [PATCH 0715/1375] ixgbe: Reduce VT code indent in set_vfta by
 introducing jump label

In order to clear the way for upcoming work I thought it best to drop the
level of indent in the ixgbe_set_vfta_generic function.  Most of the code
is held in the virtualization specific section.  So the easiest approach is
to just add a jump label and jump past the bulk of the code if it is not
enabled.

Subject: [PATCH 0716/1375] ixgbe: Simplify configuration of setting VLVF and
 VLVFB

This patch addresses several issues within the VLVF and VLVFB
configuration

First was the fact that code was overly complicated with multiple
conditional paths depending on if we adding or removing and which bit we
were going to add or remove.  Instead of messing with all that I have
simplified it by using (vid / 32) and (1 - vid / 32) to identify our
register and the other vlvfb register.

Second was the fact that we were likely leaking a few packets into the PF
in cases where we were deleting an entry and the VFTA filter for that entry
as the ordering was such that we deleted the pool and then the VLAN filter
instead of the other way around.  I have updated that by adding a check for
no bits being set and if that occurs we clear things up in the proper
order.

Subject: [PATCH 0717/1375] ixgbe: Add support for adding/removing VLAN on PF
 bypassing the VLVF

This patch adds support for bypassing the VLVF entry creation when the PF
is adding a new VLAN.  The advantage to doing this is that we can then save
the VLVF entries for the VFs which must have them in order to function,
versus the PF which can fall back on the default pool entry.

Subject: [PATCH 0718/1375] ixgbe: Reorder search to work from the top down
 instead of bottom up

This patch is meant to reduce the complexity of the search function used
for finding a VLVF entry associated with a given VLAN ID.  The previous
code was searching from bottom to top.  I reordered it to search from top
to bottom.  In addition I pulled an AND statement out of the loop and
instead replaced it with an OR statement outside the loop.  This should
help to reduce the overall size and complexity of the function.

There was also some formatting I cleaned up in regards to whitespace and
such.

Subject: [PATCH 0719/1375] ixgbe: Add support for VLAN promiscuous with SR-IOV

This patch adds support for VLAN promiscuous with SR-IOV enabled.

The code prior to this patch was only adding the PF to VLANs that the VF
had added.  As such enabling promiscuous mode would actually not add any
additional VLAN filters so visibility was limited.  This lead to a number
of issues as the bridge and OVS would expect us to accept all VLAN tagged
packets when promiscuous mode was enabled, and instead we would filter out
most if not all depending on the configuration of the PF.

With this patch what we do is set all the bits in the VFTA and all of the
VLVF bits associated with the pool belonging to the PF.  By doing this the
PF is guaranteed to receive all VLAN tagged traffic associated with the RAR
filters assigned to the PF.  In addition we will clean up those same bits
in the event of promiscuous mode being disabled.

Subject: [PATCH 0720/1375] ixgbe: Fix VLAN promisc in relation to SR-IOV

This patch is a follow-on for enabling VLAN promiscuous and allowing the PF
to add VLANs without adding a VLVF entry.  What this patch does is go
through and free the VLVF registers if they are not needed as the VLAN
belongs only to the PF which is the default pool.

Subject: [PATCH 0721/1375] ixgbe: Clear stale pool mappings

This patch makes certain that we clear the pool mappings added when we
configure default MAC addresses for the interface.  Without this we run the
risk of leaking an address into pool 0 which really belongs to VF 0 when
SR-IOV is enabled.

Subject: [PATCH 0722/1375] ixgbe: Clean stale VLANs when changing port VLAN or
 resetting

This patch guarantees that the VFs do not have access to VLANs that they
were not supposed to.  What this patch does is add code so that we delete
the previous port VLAN after adding a new one, and if we reset the VF we
clear all of the filters associated with it.

Previously the code was leaving all previous VLANs mapped to the VF and
they didn't get deleted unless the VF specifically requested it or if the
PF itself was reset.

with certain link partners. Also setting the advertised speed will
not work so we do not report it as supported to avoid confusion.

Subject: [PATCH 0724/1375] bpf, inode: allow for rename and link ops

Add support for renaming and hard links to the fs. Most of this can be
implemented by using simple library operations under the same constraints
that we don't use a reserved name like elsewhere. Linking can be useful
to share/manage things like maps across subsystem users. It works within
the file system boundary, but is not allowed for directories.

Symbolic links are explicitly not implemented here, as it can be better
done already by doing bind mounts inside bpf fs to set up shared directories
f.e. useful when using volumes in docker containers that map a private
working directory into /sys/fs/bpf/ which contains itself a bind mounted
path from the host's /sys/fs/bpf/ mount that is shared among multiple
containers. For single maps instead of whole directory, hard links can
be easily used to do the same.

Tested with objdump of binary before and after, no changes to code.

Subject: [PATCH 0726/1375] i40e: properly delete VF MAC filters

The virtual channel interface was using incorrect semantics to remove
MAC addresses, which would leave incorrect filters active when using
VLANs. To correct this, add a new function that unconditionally removes
MAC addresses from all VLANs, and call this function when the VF
requests a MAC filter removal.

Subject: [PATCH 0727/1375] i40e: don't add zero MAC filter

When VFs are created, the MAC address defaults to all zeros, indicating
to the VF driver that it should use a random MAC address. However, the
PF driver was incorrectly adding this zero MAC to the filter table,
along with the VF's randomly generated MAC address.

Check for a good address before adding the default filter. While we're
at it, make the error message a bit more useful.

If the driver gets unloaded during reset recovery, it's possible
that it will attempt to free resources when they're already free.

Add a check to make sure that the Tx and Rx rings actually exist
before dereferencing them to free resources.

Subject: [PATCH 0731/1375] i40e: hush little warnings

These messages seem big and scary, but they're really not. The driver
can fully recover from any of these. The overflow error in particular
can happen when enabling a bunch of VFs and the VF driver is not
blacklisted.

Since these messages are really for debugging purposes, reclassify
them as such.

Subject: [PATCH 0732/1375] i40e/i40evf: Add a new offload for RSS PCTYPE V2
 for X722

X722 supports Expanded version of TCP, UDP PCTYPES for RSS.
Add a Virtchnl offload to support this.

Without this patch with X722 devices, driver will set wrong PCTYPES
for VF and UDP flows will not fan out.

Subject: [PATCH 0733/1375] i40e: clean whole mac filter list

Clean the whole mac filter list when resetting after an intermediate
add or delete push to the firmware.  The code had evolved from using
a list from the stack to a heap allocation, but the memset() didn't
follow the change correctly.  This now cleans the whole list rather
that just part of the first element.

Subject: [PATCH 0737/1375] iwlwifi: mvm: set default new STA as non-aggregated

When sending the first ADD_STA HCMD for a STA, the %add_modify
field indicates an addition of a STA and not a modification
of one. In such a case, all fields of the HCMD are used to
initialize the corresponding fields in the FW, regardless of
what bits are set in %modify_mask.

Set the %tid_disable_tx field to mvm_sta->tid_disable_agg in
iwl_mvm_sta_send_to_fw(). If the STA is only updated this will
have no effect, but if it is added - it will make sure the
STA starts with the correct queues - if any - configured as
non-aggregated by default (until told otherwise).

Klocwork pointed these out. There is a theoretical possibility
that rate->index might be set to IWL_RATE_INVALID (15).
This could trigger an out of bounds access on ht_vht_rates or
legacy_rates arrays. Fix it by adding some checks.

commit 9a4c830007817e ("iwlwifi: mvm: refactor d3 key
update functions") refactored some code into
iwl_mvm_wowlan_config_key_params() function, but the
return value was never checked, and not all the function
flows returned valid values. fix it.

Subject: [PATCH 0745/1375] iwlwifi: pcie: allow the op_mode to block the tx
 queues

In certain flows (see next patches), the op_mode may need to
block the Tx queues for a short period. Provide an API for
that. The transport is in charge of counting the number of
times the queues are blocked since the op_mode may block the
queues several times in a row before unblocking them.

This allows the op_mode to request from the transport to
call a callback when an ASYNC commands is completed by
the firmware. The same callback will be called for all the
commands. Pass the command whose response triggers the
callback as a parameter to the callback itself.

Subject: [PATCH 0747/1375] iwlwifi: block the queues when we send ADD_STA for
 uAPSD

We send an ADD_STA to instruct the firmware to release
frames despite the peer being in PS.
Since the ADD_STA command and the Tx frame that comes
immediately afterwards can be reordered by the DMA engine,
we need to block the Tx queues until the firmware replies
with the ADD_STA response.

Subject: [PATCH 0752/1375] e1000: fix data race between tx_ring->next_to_clean

e1000_clean_tx_irq cleans buffers and sets tx_ring->next_to_clean,
then e1000_xmit_frame reuses the cleaned buffers. But there are no
memory barriers when buffers gets recycled, so the recycled buffers
can be corrupted.

Use smp_store_release to update tx_ring->next_to_clean and
smp_load_acquire to read tx_ring->next_to_clean to properly
hand off buffers from e1000_clean_tx_irq to e1000_xmit_frame.

The data race was found with KernelThreadSanitizer (KTSAN).

Upon looking at the igb driver, I see that igb_rd32() attempted to read from
hw_addr and failed, so it set hw->hw_addr to NULL and spit out the message
in the log output above, "PCIe link lost, device now detached".

Well, now that hw_addr is NULL, the attempt to call pci_iounmap is obviously
not going to go well. As suggested by Mark Rustad, do something similar to
what ixgbe does, and save a copy of hw_addr as adapter->io_addr, so we can
still call pci_iounmap on it on teardown. Additionally, for consistency,
make the pci_iomap call assignment directly to io_addr, so map and unmap
match.

Subject: [PATCH 0755/1375] igb: use the correct i210 register for EEMNGCTL

The i210 has two EEPROM access registers that are located in
non-standard offsets: EEARBC and EEMNGCTL. EEARBC was fixed previously
and EEMNGCTL should also be corrected.

Subject: [PATCH 0756/1375] e1000: clean up the checking logic

The checking logic needed some clean-up work, so we rewrite it by
checking for break first. With that change in place, we can even move
the second check for goto statement outside of the loop.

As this is merely a cleanup, no functional change is involved. The
questionable 'tmp != 0xFF' is intentionally left alone.

Mark Rustad and Alexander Duyck contributed to this patch.

Subject: [PATCH 0764/1375] igb: fix NULL derefs due to skipped SR-IOV enabling

The combined effect of commits 6423fc3416 ("igb: do not re-init SR-IOV
during probe") and ceee3450b3 ("igb: make sure SR-IOV init uses the
right number of queues") causes VFs no longer getting set up, leading
to NULL pointer dereferences due to the adapter's ->vf_data being NULL
while ->vfs_allocated_count is non-zero. The first commit not only
neglected the side effect of igb_sriov_reinit() that the second commit
tried to account for, but also that of setting IGB_FLAG_HAS_MSIX,
without which igb_enable_sriov() is effectively a no-op. Calling
igb_{,re}set_interrupt_capability() as done here seems to address this,
but I'm not sure whether this is better than sinply reverting the other
two commits.

Subject: [PATCH 0765/1375] iwlwifi: mvm: close the SP if we send fewer frames
 than expected in SP

When we have holes in the BA window, there might be frames
that have been ACKed between the read and the right
pointers. This means that these frames won't be scheduled
again by the SCD and the firwmare won't see them.
This invalidates the number of frames we tell the firmware
to send. When we detect this case, tell mac80211 to close
the SP and to send an EOSP so that the firmware can be in
sync.

Subject: [PATCH 0766/1375] igb: improve handling of disconnected adapters

Clean up array_rd32 so that it uses igb_rd32 the same as rd32, per the
suggestion of Alexander Duyck, and use io_addr in more places, so that
we don't have the need to call E1000_REMOVED (which simply looks for a
null hw_addr) nearly as much.

Subject: [PATCH 0768/1375] iwlwifi: avoid d0i3 commands when no/init ucode is
 loaded

d0i3 commands are not supported in the init image, so take
a reference to ensure we don't enter d0i3 during init image,
and additional checks to prevent d0i3 commands when no
fw image is loaded.

Add a few WARN_ON_ONCE to the d0i3 enter/exit commands
to ensure we send d0i3 commands only when the normal
ucode is loaded.

Subject: [PATCH 0770/1375] iwlwifi: replace d0i3_mode and wowlan_d0i3 with
 more generic variables

The d0i3_mode variable is used to distinguish between transports that
handle d0i3 entry during suspend by themselves (i.e. the slave
transports) and those which rely on the op_mode layer to do it.  The
reason why the former do it by themselves is that they need to
transition from d0i3 in runtime_suspend into d0i3 in system-wide
suspend and this transition needs to happen before the op_mode's
suspend flow is called.

The wowlan_d0i3 element is also a bit confusing, because it just
reflects the wowlan->any value for the trans to understand.  This is a
bit unclear in the code and not generic enough for future use.

To make it clearer and to generalize the platform power mode settings,
introduce two variables to indicate the platform power management
modes used by the transport.

Additionally, in order not to take too big a step in one patch, treat
this new variables semantically in the same way as the old d0i3_mode
element, introducing a iwl_mvm_enter_d0i3_on_suspend() function to
help with that.

This commit also adds the foundation for a new concept where the
firmware configuration state (i.e. D0, D3 or D0i3) is abstracted from
the platform PM mode we are in (i.e. runtime suspend or system-wide
suspend).

+ * In system-wide power management the entire platform goes into a low

+ * device is configured as a wakeup source for the entire platform.
+ * This is usually triggered by userspace activity (e.g. the user
+ * presses the suspend button or a power management daemon decides to
+ * put the platform in low power mode).  The device's behavior in this
+ * mode is dictated by the wake-on-WLAN configuration.
+ *
+ * In runtime power management, only the devices which are themselves
+ * idle enter a low power state.  This is done at runtime, which means
+ * that the entire system is still running normally.  This mode is
+ * usually triggered automatically by the device driver and requires
+ * the ability to enter and exit the low power modes in a very short
+ * time, so there is not much impact in usability.
+ *
+ * The terms used for the device's behavior are as follows:
+ *
+ *	- D0: the device is fully powered and the host is awake;
+ *	- D3: the device is in low power mode and only reacts to
+ *		specific events (e.g. magic-packet received or scan
+ *		results found);
+ *	- D0I3: the device is in low power mode and reacts to any
+ *		activity (e.g. RX);
+ *
+ * These terms reflect the power modes in the firmware and are not to

Subject: [PATCH 0775/1375] fm10k: consistently refer to VLANs and VLAN IDs

Instead of using lowercase vlan, vid, or VID, always use VLAN or VLAN ID
in comments when referring to VLANs. The original driver code was
consistent, but recent patches have not been as consistent with this
naming scheme.

Subject: [PATCH 0777/1375] fm10k: conditionally compile DCB and DebugFS
 support

Rather than wrapping fm10k_dcbnl.c and fm10k_debugfs.c support with
 #ifdef blocks, just conditionally include the .o files in the Makefile.
Also, since we're modifying it, update the copyright year on the
Makefile.

Subject: [PATCH 0779/1375] fm10k: Cleanup exception handling for mailbox
 interrupt

This patch addresses two issues.

First is the fact that the fm10k_mbx_free_irq was assuming msix_entries was
valid and that will not always be the case.  As such we need to add a check
for if it is NULL.

Second is the fact that we weren't freeing the IRQ if the mailbox API
returned an error on trying to connect.

Subject: [PATCH 0783/1375] fm10k: cleanup namespace pollution

Make functions that should be static.  While we're at it, fix the function
header comment for fm10k_tlv_attr_nest_stop(), and update the copyright
header for fm10k_pf.h, fm10k_tlv.c and fm10k_tlv.h.

Subject: [PATCH 0788/1375] hv_netvsc: Fix race condition on Multi-Send Data
 field

In commit 2a04ae8acb14 ("hv_netvsc: remove locking in netvsc_send()"), the
locking for MSD (Multi-Send Data) field was removed. This could cause a
race condition between RNDIS control messages and data packets processing,
because these two types of traffic are not synchronized.
This patch fixes this issue by sending control messages out directly
without reading MSD field.

Mesh Point requires peer security key install when running
in secured mode since it's a type of peer links, otherwise peer
link will be removed due to key install failure.

MFP feature set is required to run Mesh in secured mode and
QCA988X firmware, 10.2.4.70.14-2 and above, is the only one
supporting secured Mesh at this moment.

Subject: [PATCH 0792/1375] e1000e: Switch e1000e_up to void, drop code
 checking for error result

The function e1000e_up always returns 0.  As such we can convert it to a
void and just ignore the results.  This allows us to drop some code in a
couple spots as we no longer need to worry about non-zero return values.

Subject: [PATCH 0793/1375] igb: Remove GS40G specific defines/functions

The I210 internal PHY can be accessed just as well with the access
functions shared by 82580, I350, and I354 devices. A side effect of
relying on the common functions, is that I210 cable length support
is folded back into the common case which effectively reverts the
following commit:

    commit 59f301046b276f87483b3afa3201a4273def06a9

Subject: [PATCH 0794/1375] net, cgroup: cgroup_sk_updat_lock was missing
 initializer

bd1060a1d671 ("sock, cgroup: add sock->sk_cgroup") added global
spinlock cgroup_sk_update_lock but erroneously skipped initializer
leading to uninitialized spinlock warning.  Fix it by using
DEFINE_SPINLOCK().

Subject: [PATCH 0795/1375] ravb: clear RIC1 in init instead of stop

AVB-DMAC Receive FIFO Warning interrupt is not enabled, so it is not
necessary to disable the interrupt in ravb_close().
On the other hand, this patch disables the interrupt in ravb_dmac_init() to
prevent the possibility that the interrupt is issued by the state that
a boot loader left.

Subject: [PATCH 0797/1375] netfilter: implement xt_cgroup cgroup2 path match

This patch implements xt_cgroup path match which matches cgroup2
membership of the associated socket.  The match is recursive and
invertible.

For rationales on introducing another cgroup based match, please refer
to a preceding commit "sock, cgroup: add sock->sk_cgroup".

v3: Folded into xt_cgroup as a new revision interface as suggested by
    Pablo.

v2: Included linux/limits.h from xt_cgroup2.h for PATH_MAX.  Added
    explicit alignment to the priv field.  Both suggested by Jan.

Subject: [PATCH 0798/1375] ipv6: addrconf: drop ieee802154 specific things

This patch removes ARPHRD_IEEE802154 from addrconf handling. In the
earlier days of 802.15.4 6LoWPAN, the interface type was ARPHRD_IEEE802154
which introduced several issues, because 802.15.4 interfaces used the
same type.

Since commit 965e613d299c ("ieee802154: 6lowpan: fix ARPHRD to
ARPHRD_6LOWPAN") we use ARPHRD_6LOWPAN for 6LoWPAN interfaces. This
patch will remove ARPHRD_IEEE802154 which is currently deadcode, because
ARPHRD_IEEE802154 doesn't reach the minimum 1280 MTU of IPv6.

Also we use 6LoWPAN EUI64 specific defines instead using link-layer
constanst from 802.15.4 link-layer header.

When the linear buffer of the received sk_buff is shorter than
the header, use skb_linearize(). sk_buffs with short linear buffer
happen on the sending side under high traffic, and some kernel
configurations, when allocated buffer starts just before page
boundary, and IUCV transport has to send it as two separate QDIO
buffer elements, with fist element shorter than the header.

Subject: [PATCH 0802/1375] s390-ctcm: Delete unnecessary checks before the
 function call "channel_remove"

The channel_remove() function tests whether its argument is NULL
and then returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.

Subject: [PATCH 0803/1375] qeth use common function qeth_get_setassparms_cmd

There have been 2 identical versions of function
qeth_get_setassparms_cmd() for layer 2 and layer 3.
Remove the layer 3 function qeth_l3_get_setassparms_cmd()
and call the common one named qeth_get_setassparms_cmd()
located in qeth_core_main.c

Subject: [PATCH 0804/1375] qeth: initialize net_device with carrier off

/sys/class/net/<interface>/operstate for an active qeth network
interface offen shows "unknown", which translates to "state UNKNOWN
in output of "ip link show". It is caused by a missing initialization
of the __LINK_STATE_NOCARRIER bit in the net_device state field.
This patch adds a netif_carrier_off() invocation when creating the
net_device for a qeth device.

Subject: [PATCH 0805/1375] qeth: repair SBAL elements calculation

When sending skbs, qeth determines the number of qdio SBAL elements
required. If qeth sends a fragmented skb, the SBAL element number
calculation is wrong, because the fragmented data part is added
twice in qeth_l3_tso_elements(). This patch makes sure fragmented
data is handled in qeth_elements_for_frags() only, while
qeth_l3_tso_elements() starts calculation of qdio SBAL elements just
with the linear data part of the skb.

Subject: [PATCH 0812/1375] igb: Improve cable length function for I210, etc.

Previously, the PHY-specific code to get the cable length for the
I210 internal and related PHYs was reporting the cable length of a
single pair and reporting it as the min, max, and total cable length.
Update it so that all four pairs are checked so the true min, max,
and average cable lengths are reported.

Subject: [PATCH 0814/1375] net/macb: add support for resetting PHY using GPIO

With device tree it is no more possible to reset the PHY at board
level. Furthermore, doing in the driver allow to power down the PHY when
the network interface is no more used.

This reset can't be done at the PHY driver level. The PHY must be able to
answer the to the mii bus scan to let the kernel creating a PHY device.

The patch introduces a new optional property "phy-reset-gpios" inspired
from the one use for the FEC.

Removes the ICR read in the other interrupt handler, uses EIAC to
autoclear the Other bit from ICR and IMS. This allows us to avoid
interference with Rx and Tx interrupts in the Other interrupt handler.

The information read from ICR is not needed. IMS is configured such that
the only interrupt cause that can trigger the Other interrupt is Link
Status Change.

From 0a8047ac68e50e4ccbadcfc6b6b070805b976885 Mon Sep 17 00:00:00 2001
From: Benjamin Poirier <bpoirier@suse.com>
Date: Mon, 9 Nov 2015 15:50:21 -0800
Subject: [PATCH 0818/1375] e1000e: Fix msi-x interrupt automask

Since the introduction of 82574 support in e1000e, the driver has worked
on the assumption that msi-x interrupt generation is automatically
disabled after each irq. As it turns out, this is not the case.
Currently, rx interrupts can fire multiple times before and during napi
processing. This can be a problem for users because frames that arrive
in a certain window (after adapter->clean_rx() but before
napi_complete_done() has cleared NAPI_STATE_SCHED) generate an interrupt
which does not lead to napi_schedule(). These frames sit in the rx queue
until another frame arrives (a tcp retransmit for example).

While the EIAC and CTRL_EXT registers are properly configured for irq
automask, the modification of IAM in e1000_configure_msix() is what
prevents automask from working as intended.

This patch removes that erroneous write and fixes interrupt rearming for
tx interrupts. It also clears IAME from CTRL_EXT. This is not strictly
necessary for operation of the driver but it is to avoid disruption from
potential programs that access the registers directly, like `ethregs -c`.

Subject: [PATCH 0826/1375] batman-adv: rename equiv/equal or better to similar
 or better

Since the function applies a threshold and also slightly worse
values are accepted, ''equal or better'' does not represent the
intention of the function. ''Similar or better'' represents that better.

Subject: [PATCH 0827/1375] switchdev: vlan: Use switchdev_port* in
 vlan_netdev_ops

We need to be able to propagate static FDB entries and certain bridge
port attributes (e.g. learning, flooding) down to the port netdev
driver when bridge port is a VLAN interface.

Achieve that by setting ndo_bridge* and ndo_fdb* in vlan_netdev_ops to
the corresponding switchdev_port* functions. This is consistent with
team and bond devices.

Subject: [PATCH 0828/1375] switchdev: Pass original device to port netdev
 driver

switchdev drivers need to know the netdev on which the switchdev op was
invoked. For example, the STP state of a VLAN interface configured on top
of a port can change while being member in a bridge. In this case, the
underlying driver should only change the STP state of that particular
VLAN and not of all the VLANs configured on the port.

However, current switchdev infrastructure only passes the port netdev down
to the driver. Solve that by passing the original device down to the
driver as part of the required switchdev object / attribute.

This doesn't entail any change in current switchdev drivers. It simply
enables those supporting stacked devices to know the originating device
and act accordingly.

Subject: [PATCH 0829/1375] mlxsw: spectrum: Allocate active VLANs only for
 port netdevs

When adding support for bridges between VLAN interfaces, we'll introduce
a new entity called a vPort, which is a represntation of the VLAN
interface in the hardware.

The main difference between a vPort and a physical port is that several
FIDs can be bound to the latter, whereas only one (called a vFID) can be
bound to the first.

Therefore, it makes sense to use the same struct to represent the two,
but to only allocate the 'active_vlans' bitmap in case of a physical
port.

Subject: [PATCH 0830/1375] mlxsw: spectrum: Split vFID range in two

Up until now we used a 1:1 mapping - based on VID - to map a VLAN
interface to a vFID. However, a different scheme is needed in order to
support bridges between VLAN interfaces, as all the member interfaces -
which can have different VIDs - need to share the same vFID.

Solve that by splitting the vFID range in two:
 1. Non-bridged VLAN interfaces
 2. Bridged VLAN interfaces

When a VLAN interface is created, assign it the next available vFID in
the first range, unless one already exists for that VID or number of
vFIDs in the range was exceeded. When interface is removed, free the
vFID, unless other interfaces are mapped to it.

To accomplish the above:
 1. Store the VID to vFID mapping in a new struct (mlxsw_sp_vfid), which
    has a global context and holds a reference count.
 2. Create a vPort (dummy in case of bridge SELF invocation) on top of
    of the physical port and hold a reference to the associated vFID.

Next patches in the series will add the missing infrastructure for the
second range and transfer vPorts between the two ranges according to the
received notifications.

Subject: [PATCH 0831/1375] mlxsw: spectrum: Use appropriate parameter name

The __mlxsw_sp_port_flood_set function is now used to configure flooding
for both FIDs and vFIDs, so change the parameter name to 'idx' instead
of 'fid'. This is also consistent with hardware documentation.

Subject: [PATCH 0832/1375] mlxsw: spectrum: Add another flood table for vFIDs

We previously used only one flood table for packets classified to vFIDs.
However, since we are going to add support for bridges between VLAN
interfaces (mapped to vFIDs) we need to add one more flood table.

That way we can separate the flooding domain of unknown unicast traffic
from all the rest and support flood control (as we do with the 802.1Q
bridge).

Subject: [PATCH 0833/1375] mlxsw: spectrum: Use FID instead of VID when
 accessing FDB

In the Spectrum ASIC - unlike SwitchX-2 - FDB access is done by
specifying FID as parameter and not VID.

Change the relevant variables and parameters names to reflect that.

Note that this was OK up until now, since FID was always equal to VID,
but with the introduction of VLAN interfaces this is no longer the case.

Subject: [PATCH 0834/1375] mlxsw: spectrum: Adjust switchdev ops for VLAN
 devices

switchdev ops can now be called for VLAN devices and we need to be
prepared for it. Until now they were only called for the port netdev.

Use the newly propagated orig_dev passed as part of the switchdev
attr/obj and determine whether the original device is a VLAN device. If
so, act accordingly, otherwise continue as usual.

Subject: [PATCH 0835/1375] mlxsw: spectrum: Adjust FDB notifications for VLAN
 devices

FDB notifications contain the FID and port (or LAG ID) on which the MAC
was learned. In the case of the 802.1Q bridge one can easily derive the
matching VID - as FID equals VID - and generate the appropriate
notification for the software bridge. With VLAN devices this is no
longer the case, as these are associated with a vFID.

Solve that by converting the FID to a vFID and lookup the matching VLAN
device. From that derive the VID and whether learning (and learning
sync) should occur.

Subject: [PATCH 0836/1375] mlxsw: spectrum: Handle VLAN devices linking /
 unlinking

When a VLAN interface is configured on top of a physical port we should
associate the VLAN device with the matching vPort. Likewise, when it's
removed, we should revert back to the underlying port netdev.

While not a must, this is consistent with port netdevs and also provides
a more accurate error printing via netdev_err() and friends.

Subject: [PATCH 0837/1375] mlxsw: spectrum: Add support for VLAN devices
 bridging

All the member VLAN devices in a bridge need to share the same vFID.

To achieve that, expand the vFID struct to include the associated bridge
device (or lack of) and allow one to lookup a vFID based on a bridge
device.

When joining a bridge, lookup the relevant vFID or create one if none
exists. Next, make the VLAN device use the vFID.

Leaving a bridge can either occur because a user removed the VLAN device
from a bridge or because the VLAN device was deleted by the user. In the
latter case the bridge's teardown sequence is invoked after the hardware
vPort is already gone. Therefore, when unlinking the VLAN device from
the real device, check if the associated vPort is bridged and act
accordingly. The bridge's notification will be ignored in this case.

Note that bridging a VLAN interface with an ordinary port netdev is
currently not supported, but not forbidden. This will be addressed in a
follow-up patchset.

Subject: [PATCH 0838/1375] mlxsw: reg: Add lag_vid field to SFD register

Unicast LAG records in the Switch Filtering Database (SFD) register have
a lag_vid field indicating the VLAN ID in case of vFIDs. This field is
no longer reserved since we are going to add support for VLAN devices on
top of LAG.

Add the lag_vid field to be used by VLAN devies on top of LAG.

Subject: [PATCH 0840/1375] mlxsw: spectrum: Add support for VLAN devices on
 top of LAG

When creating a VLAN device on top of LAG, we are basically creating a
vPort on top of each of the port netdevs member in the LAG. Therefore,
these vPorts should inherit both the LAG status and LAG ID from the
underlying port netdevs.

In addition, when the VLAN device joins or leaves a bridge each of the
underlying vPorts should know about it and act accordingly. This is
achieved by propagating the VLAN event down to the lower devices.

The SCTP checksum is really a CRC and is very different from the
standards 1's complement checksum that serves as the checksum
for IP protocols. This offload interface is also very different.
Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRC to highlight these
differences. The term CSUM should be reserved in the stack to refer
to the standard 1's complement IP checksum.

Subject: [PATCH 0844/1375] fcoe: Use CHECKSUM_PARTIAL to indicate CRC offload

When setting up CRC offload set ip_summed to CHECKSUM_PARTIAL
instead of CHECKSUM_UNNECESSARY. This is consistent with the
definition of CHECKSUM_PARTIAL.

The only driver that seems to be advertising NETIF_F_FCOE_CRC is
ixgbe. AFICT the driver does not look at ip_summed for FCOE and
just assumes that CRC is being offloaded.

Subject: [PATCH 0845/1375] net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK

The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.

This patch:
  - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
    NETIF_F_ALL_CSUM is being used as a mask).
  - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to
    use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.

From c8cd0989bd151fda87bbf10887b3df18021284bc Mon Sep 17 00:00:00 2001
From: Tom Herbert <tom@herbertland.com>
Date: Mon, 14 Dec 2015 11:19:44 -0800
Subject: [PATCH 0846/1375] net: Eliminate NETIF_F_GEN_CSUM and
 NETIF_F_V[46]_CSUM

These netif flags are unnecessary convolutions. It is more
straightforward to just use NETIF_F_HW_CSUM, NETIF_F_IP_CSUM,
and NETIF_F_IPV6_CSUM directly.

This patch also:
    - Cleans up can_checksum_protocol
    - Simplifies netdev_intersect_features

Subject: [PATCH 0847/1375] tcp: Fix conditions to determine checksum offload

In tcp_send_sendpage and tcp_sendmsg we check the route capabilities to
determine if checksum offload can be performed. This check currently
does not take the IP protocol into account for devices that advertise
only one of NETIF_F_IPV6_CSUM or NETIF_F_IP_CSUM. This patch adds a
function to check capabilities for checksum offload with a socket
called sk_check_csum_caps. This function checks for specific IPv4 or
IPv6 offload support based on the family of the socket.

Subject: [PATCH 0848/1375] net: Add driver helper functions to determine
 checksum offloadability

Add skb_csum_offload_chk driver helper function to determine if a
device with limited checksum offload capabilities is able to offload the
checksum for a given packet.

This patch includes:
  - The skb_csum_offload_chk function. Returns true if checksum is
    offloadable, else false. Optionally, in the case that the checksum
    is not offloable, the function can call skb_checksum_help to resolve
    the checksum. skb_csum_offload_chk also returns whether the checksum
    refers to an encapsulated checksum.
  - Definition of skb_csum_offl_spec structure that caller uses to
    indicate rules about what it can offload (e.g. IPv4/v6, TCP/UDP only,
    whether encapsulated checksums can be offloaded, whether checksum with
    IPv6 extension headers can be offloaded).
  - Ancilary functions called skb_csum_offload_chk_help,
    skb_csum_off_chk_help_cmn, skb_csum_off_chk_help_cmn_v4_only.

-/* A. Checksumming of received packets by device.
+/* The interface for checksum offload between the stack and networking drivers
+ * is as follows...
+ *
+ * A. IP checksum related features
+ *
+ * Drivers advertise checksum offload capabilities in the features of a device.
+ * From the stack's point of view these are capabilities offered by the driver,
+ * a driver typically only advertises features that it is capable of offloading
+ * to its device.
+ *
+ * The checksum related features are:
+ *
+ *	NETIF_F_HW_CSUM	- The driver (or its device) is able to compute one
+ *			  IP (one's complement) checksum for any combination
+ *			  of protocols or protocol layering. The checksum is
+ *			  computed and set in a packet per the CHECKSUM_PARTIAL
+ *			  interface (see below).
+ *
+ *	NETIF_F_IP_CSUM - Driver (device) is only able to checksum plain
+ *			  TCP or UDP packets over IPv4. These are specifically
+ *			  unencapsulated packets of the form IPv4|TCP or
+ *			  IPv4|UDP where the Protocol field in the IPv4 header
+ *			  is TCP or UDP. The IPv4 header may contain IP options
+ *			  This feature cannot be set in features for a device
+ *			  with NETIF_F_HW_CSUM also set. This feature is being
+ *			  DEPRECATED (see below).
+ *
+ *	NETIF_F_IPV6_CSUM - Driver (device) is only able to checksum plain
+ *			  TCP or UDP packets over IPv6. These are specifically
+ *			  unencapsulated packets of the form IPv6|TCP or
+ *			  IPv4|UDP where the Next Header field in the IPv6
+ *			  header is either TCP or UDP. IPv6 extension headers
+ *			  are not supported with this feature. This feature
+ *			  cannot be set in features for a device with
+ *			  NETIF_F_HW_CSUM also set. This feature is being
+ *			  DEPRECATED (see below).
+ *
+ *	NETIF_F_RXCSUM - Driver (device) performs receive checksum offload.
+ *			 This flag is used only used to disable the RX checksum
+ *			 feature for a device. The stack will accept receive
+ *			 checksum indication in packets received on a device
+ *			 regardless of whether NETIF_F_RXCSUM is set.
+ *
+ * B. Checksumming of received packets by device. Indication of checksum
+ *    verification is in set skb->ip_summed. Possible values are:
  *
  * CHECKSUM_NONE:
  *
- *   Device failed to checksum this packet e.g. due to lack of capabilities.
+ *   Device did not checksum this packet e.g. due to lack of capabilities.
  *   The packet contains full (though not verified) checksum in packet but

+ *   NETIF_F_FCOE_CRC - This feature indicates that a device is capable of

+ *
+ * In the case of a GSO packet (skb_is_gso(skb) is true), checksum offload

+ * gso_type is SKB_GSO_TCPV4 or SKB_GSO_TCPV6, TCP checksum offload as
+ * part of the GSO operation is implied. If a checksum is being offloaded
+ * with GSO then ip_summed is CHECKSUM_PARTIAL, csum_start and csum_offset

Subject: [PATCH 0850/1375] stmmac: create of compatible mdio bus for stmmac
 driver

The DSA driver needs to be passed a reference to an mdio bus. Typically
the mac is configured to use a fixed link but the mdio bus still needs
to be registered so that it con configure the switch.
This patch follows the same process as the altera tse ethernet driver for
creation of the mdio bus.

Subject: [PATCH 0852/1375] stmmac: Fix calculations for ptp counters when
 clock input = 50Mhz.

stmmac_config_sub_second_increment set the sub second increment to 20ns.
Driver is configured to use the fine adjustment method where the sub second
register is incremented when the acculumator incremented by the addend
register wraps overflows. This accumulator is update on every ptp clk
cycle. If a ptp clk with a period of greater than 20ns was used the
sub second register would not get updated correctly.

Instead set the sub sec increment to twice the period of the ptp clk.
This result in the addend register being set mid range and overflow
the accumlator every 2 clock cycles.

Subject: [PATCH 0853/1375] stmmac: socfpga: Provide dt node to config ptp clk
 source.

Provides an options to use the ptp clock routed from the Altera FPGA
fabric. Instead of the defalt eosc1 clock connected to the ARM HPS core.
This setting affects all emacs in the core as the ptp clock is common.

From 7f00feaf107645d95a6d87e99b4d141ac0a08efd Mon Sep 17 00:00:00 2001
From: Tom Herbert <tom@herbertland.com>
Date: Tue, 15 Dec 2015 15:41:38 -0800
Subject: [PATCH 0857/1375] ila: Add generic ILA translation facility

This patch implements an ILA tanslation table. This table can be
configured with identifier to locator mappings, and can be be queried
to resolve a mapping. Queries can be parameterized based on interface,
direction (incoming or outoing), and matching locator.  The table is
implemented using rhashtable and is configured via netlink (through
"ip ila .." in iproute).

The table may be used as alternative means to do do ILA tanslations
other than the lw tunnels

Subject: [PATCH 0858/1375] net: diag: split inet_diag_dump_one_icsk into two

Currently, inet_diag_dump_one_icsk finds a socket and then dumps
its information to userspace. Split it into a part that finds the
socket and a part that dumps the information.

Subject: [PATCH 0860/1375] net: diag: Support SOCK_DESTROY for inet sockets.

This passes the SOCK_DESTROY operation to the underlying protocol
diag handler, or returns -EOPNOTSUPP if that handler does not
define a destroy operation.

Most of this patch is just renaming functions. This is not
strictly necessary, but it would be fairly counterintuitive to
have the code to destroy inet sockets be in a function whose name
starts with inet_diag_get.

blocking calls on the socket to fail fast with ECONNABORTED and
causes a protocol close of the socket. It informs the other end
of the connection by sending a RST, i.e., initiating a TCP ABORT
as per RFC 793. ECONNABORTED was chosen for consistency with
FreeBSD.

Subject: [PATCH 0862/1375] sctp: use GFP_KERNEL in sctp_init()

modules init functions being called from process context, we better
use GFP_KERNEL allocations to increase our chances to get these
high-order pages we want for SCTP hash tables.

This mostly matters if SCTP module is loaded once memory got fragmented.

Subject: [PATCH 0863/1375] batman-adv: detect local excess vlans in TT request

If the local representation of the global TT table of one originator has
more VLAN entries than the respective TT update, there is some
inconsistency present. By detecting and reporting this inconsistency,
the global table gets updated and the excess VLAN will get removed in
the process.

Subject: [PATCH 0867/1375] batman-adv: lock crc access in bridge loop
 avoidance

We have found some networks in which nodes were constantly requesting
other nodes BLA claim tables to synchronize, just to ask for that again
once completed. The reason was that the crc checksum of the asked nodes
were out of sync due to missing locking and multiple writes to the same
crc checksum when adding/removing entries. Therefore the asked nodes
constantly reported the wrong crc, which caused repeating requests.

To avoid multiple functions changing a backbone gateways crc entry at
the same time, lock it using a spinlock.

Subject: [PATCH 0868/1375] iwlwifi: expose fw usniffer mode to more utilities

Today, in order to configure fw in usniffer mode, the ucode
must have the corresponding tlv, which is revealed to the driver
while parsing the ucode.

Expose the mode of the usniffer to other utilities in the driver
(other than the ucode parser) by passing back a pointer to the value.
This can be very useful for allowing configuring the fw dbg data
using an external configuration file, because this configuration
depends on the fw usniffer mode.

Subject: [PATCH 0869/1375] iwlwifi: mvm: change protocol offload flows

RFC4862 states that "In all cases, a node MUST NOT respond to
a Neighbor Solicitation for a tentative address".
Currently the driver configures the NS offload and does not wait
for address to become permanent, thus violating the RFC.
Just removing the address from the address list is not good enough
for all cases, since the NS messages are needed for the duplicate
address detection and should not be discarded.

For d0i3 disable NS offload. Put tentative address in the address
list so the NS packet will not be filtered out by ucode.
For D3 the platform will not wake from NS packets - so enable
NS offload while removing the tentative address from the list.

Given that now NS offload might be disabled, and that the ucode
uses the IP data for other puroposes (L3 filtering) add two
independent flags indicating if IPv4\IPv6 data is valid.

Subject: [PATCH 0871/1375] ssb: pick SoC invariants code from MIPS BCM47xx
 arch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There is code in ssb fetching "invariants" that is basically a set of
board specific data. Every host requires its own implementation of
reading function. In ssb we have support for PCI, PCMCIA & SDIO.
For some (historical?) reason code reading "invariants" for SoC was
placed in arch code and provided by a callback. This is not needed
nowadays, so lets move that into ssb. This way we keep all "invariants"
functions in a single module making code cleaner.

Subject: [PATCH 0872/1375] net: sctp: dynamically enable or disable pf state

As we all know, the value of pf_retrans >= max_retrans_path can
disable pf state. The variables of pf_retrans and max_retrans_path
can be changed by the userspace application.

Sometimes the user expects to disable pf state while the 2
variables are changed to enable pf state. So it is necessary to
introduce a new variable to disable pf state.

According to the suggestions from Vlad Yasevich, extra1 and extra2
are removed. The initialization of pf_enable is added.

Subject: [PATCH 0877/1375] i40e: Call geneve_get_rx_port to get the existing
 Geneve ports

This patch adds a call to geneve_get_rx_port in i40e so that when it
comes up it can learn about the existing geneve tunnels.

Subject: [PATCH 0878/1375] net: Pass ndm_state to route netlink FDB
 notifications.

Before this change applications monitoring FDB notifications
were not able to determine whether a new FDB entry is permament
or not:
bridge fdb add f1:f2:f3:f4:f5:f8 dev sw0p1 temp self
bridge fdb add f1:f2:f3:f4:f5:f9 dev sw0p1 self

bridge monitor fdb

f1:f2:f3:f4:f5:f8 dev sw0p1 self permanent
f1:f2:f3:f4:f5:f9 dev sw0p1 self permanent

With this change ndm_state from the original netlink message
is passed to the new netlink message sent as notification.

bridge fdb add f1:f2:f3:f4:f5:f6 dev sw0p1 self
bridge fdb add f1:f2:f3:f4:f5:f7 dev sw0p1 temp self

bridge monitor fdb
f1:f2:f3:f4:f5:f6 dev sw0p1 self permanent
f1:f2:f3:f4:f5:f7 dev sw0p1 self static

If a tun interface is turned down, we should not allow packet injection
into the kernel.

Kernel does not send packets to the tun already.

TUNATTACHFILTER can not be used as only tun_net_xmit() is taking care
of it.

Subject: [PATCH 0887/1375] net/macb: Update device tree binding for resetting
 PHY using GPIO

Instead of being at the MAC level the reset gpio preperty is moved at the
PHY child node level. It is still managed by the MAC, but from the point
of view of the binding it make more sense to be part of the PHY node.

This commit also fixes a build errors if GPIOLIB is not selected.

Subject: [PATCH 0888/1375] net: qmi_wwan: ignore bogus CDC Union descriptors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The CDC descriptors found on these vendor specific functions should
not be considered authoritative.  They seem to be ignored by drivers
for other systems, and the quality is therefore low.

One device (1e0e:9001) has been reported to have such a bogus union
descriptor on the QMI function, making it fail probing even if the
device id was dynamically added.  The report was not complete enough
to allow adding a device entry for this modem. But this should at
least fix the dynamic id probing problem.

Subject: [PATCH 0889/1375] team: Advertise tunneling offload features

When the underlying device supports offloads encapulated traffic,
we need to reflect that through the hw_enc_features field of the
team net-device.

This will cause the xmit path in the core networking stack to provide
team with encapsulated GSO frames to offload into the HW etc.

Using this over Mellanox ConnectX3-pro (mlx4 driver) card that supports
VXLAN offloads we got 36.0 Gbits/sec using eight iperf streams.

Subject: [PATCH 0890/1375] netfilter: meta: add support for setting
 skb->pkttype

This allows to redirect bridged packets to local machine:

ether type ip ether daddr set aa:53:08:12:34:56 meta pkttype set unicast
Without 'set unicast', ip stack discards PACKET_OTHERHOST skbs.

It is also useful to add support for a '-m cluster like' nft rule
(where switch floods packets to several nodes, and each cluster node
 node processes a subset of packets for load distribution).

Mangling is restricted to HOST/OTHER/BROAD/MULTICAST, i.e. you cannot set
skb->pkt_type to PACKET_KERNEL or change PACKET_LOOPBACK to PACKET_HOST.

net/ipv6/ila/ila_xlat.c:235:27: error: array type has incomplete element type 'struct nf_hook_ops'
 static struct nf_hook_ops ila_nf_hook_ops[] __read_mostly = {

Date: Wed, 16 Dec 2015 16:44:38 +0100
Subject: [PATCH 0892/1375] ipv6: addrconf: use stable address generator for
 ARPHRD_NONE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a new address generator mode, using the stable address generator
with an automatically generated secret. This is intended as a default
address generator mode for device types with no EUI64 implementation.
The new generator is used for ARPHRD_NONE interfaces initially, adding
default IPv6 autoconf support to e.g. tun interfaces.

If the addrgenmode is set to 'random', either by default or manually,
and no stable secret is available, then a random secret is used as
input for the stable-privacy address generator.  The secret can be
read and modified like manually configured secrets, using the proc
interface.  Modifying the secret will change the addrgen mode to
'stable-privacy' to indicate that it operates on a known secret.

Existing behaviour of the 'stable-privacy' mode is kept unchanged. If
a known secret is available when the device is created, then the mode
will default to 'stable-privacy' as before.  The mode can be manually
set to 'random' but it will behave exactly like 'stable-privacy' in
this case. The secret will not change.

Subject: [PATCH 0894/1375] net: Allow accepted sockets to be bound to l3mdev
 domain

Allow accepted sockets to derive their sk_bound_dev_if setting from the
l3mdev domain in which the packets originated. A sysctl setting is added
to control the behavior which is similar to sk_mark and
sysctl_tcp_fwmark_accept.

This effectively allow a process to have a "VRF-global" listen socket,
with child sockets bound to the VRF device in which the packet originated.
A similar behavior can be achieved using sk_mark, but a solution using marks
is incomplete as it does not handle duplicate addresses in different L3
domains/VRFs. Allowing sockets to inherit the sk_bound_dev_if from l3mdev
domain provides a complete solution.

Subject: [PATCH 0896/1375] bpf: add bpf_skb_load_bytes helper

When hacking tc programs with eBPF, one of the issues that come up
from time to time is to load addresses from headers. In eBPF as in
classic BPF, we have BPF_LD | BPF_ABS | BPF_{B,H,W} instructions that
extract a byte, half-word or word out of the skb data though helpers
such as bpf_load_pointer() (interpreter case).

F.e. extracting a whole IPv6 address could possibly look like ...

  union v6addr {
    struct {
      __u32 p1;
      __u32 p2;
      __u32 p3;
      __u32 p4;
    };
    __u8 addr[16];
  };

  [...]

  a.p1 = htonl(load_word(skb, off));
  a.p2 = htonl(load_word(skb, off +  4));
  a.p3 = htonl(load_word(skb, off +  8));
  a.p4 = htonl(load_word(skb, off + 12));

  [...]

  /* access to a.addr[...] */

This work adds a complementary helper bpf_skb_load_bytes() (we also
have bpf_skb_store_bytes()) as an alternative where the same call
would look like from an eBPF program:

  ret = bpf_skb_load_bytes(skb, off, addr, sizeof(addr));

Same verifier restrictions apply as in ffeedafbf023 ("bpf: introduce
current->pid, tgid, uid, gid, comm accessors") case, where stack memory
access needs to be statically verified and thus guaranteed to be
initialized in first use (otherwise verifier cannot tell whether a
subsequent access to it is valid or not as it's runtime dependent).

Subject: [PATCH 0897/1375] bpf: move clearing of A/X into classic to eBPF
 migration prologue

Back in the days where eBPF (or back then "internal BPF" ;->) was not
exposed to user space, and only the classic BPF programs internally
translated into eBPF programs, we missed the fact that for classic BPF
A and X needed to be cleared. It was fixed back then via 83d5b7ef99c9
("net: filter: initialize A and X registers"), and thus classic BPF
specifics were added to the eBPF interpreter core to work around it.

This added some confusion for JIT developers later on that take the
eBPF interpreter code as an example for deriving their JIT. F.e. in
f75298f5c3fe ("s390/bpf: clear correct BPF accumulator register"), at
least X could leak stack memory. Furthermore, since this is only needed
for classic BPF translations and not for eBPF (verifier takes care
that read access to regs cannot be done uninitialized), more complexity
is added to JITs as they need to determine whether they deal with
migrations or native eBPF where they can just omit clearing A/X in
their prologue and thus reduce image size a bit, see f.e. cde66c2d88da
("s390/bpf: Only clear A and X for converted BPF programs"). In other
cases (x86, arm64), A and X is being cleared in the prologue also for
eBPF case, which is unnecessary.

Lets move this into the BPF migration in bpf_convert_filter() where it
actually belongs as long as the number of eBPF JITs are still few. It
can thus be done generically; allowing us to remove the quirk from
__bpf_prog_run() and to slightly reduce JIT image size in case of eBPF,
while reducing code duplication on this matter in current(/future) eBPF
JITs.

Comment says "User BPF's register A is mapped to our BPF register 6",
which is actually wrong as the mapping is on register 0. This can
already be inferred from the code itself. So just remove it before
someone makes assumptions based on that. Only code tells truth. ;)

Subject: [PATCH 0899/1375] bpf, x86: detect/optimize loading 0 immediates

When sometimes structs or variables need to be initialized/'memset' to 0 in
an eBPF C program, the x86 BPF JIT converts this to use immediates. We can
however save a couple of bytes (f.e. even up to 7 bytes on a single emmission
of BPF_LD | BPF_IMM | BPF_DW) in the image by detecting such case and use xor
on the dst register instead.

Subject: [PATCH 0900/1375] bpf, test: add couple of test cases

Add couple of test cases for interpreter but also JITs, f.e. to test that
when imm32 moves are being done, upper 32bits of the regs are being zero
extended.

Without JIT:

  [...]
  [ 1114.129301] test_bpf: #43 MOV REG64 jited:0 128 PASS
  [ 1114.130626] test_bpf: #44 MOV REG32 jited:0 139 PASS
  [ 1114.132055] test_bpf: #45 LD IMM64 jited:0 124 PASS
  [...]

With JIT (generated code can as usual be nicely verified with the help of
bpf_jit_disasm tool):

  [...]
  [ 1062.726782] test_bpf: #43 MOV REG64 jited:1 6 PASS
  [ 1062.726890] test_bpf: #44 MOV REG32 jited:1 6 PASS

Subject: [PATCH 0901/1375] tcp: diag: add support for request sockets to
 tcp_abort()

Adding support for SYN_RECV request sockets to tcp_abort()
is quite easy after our tcp listener rewrite.

Note that we also need to better handle listeners, or we might
leak not yet accepted children, because of a missing
inet_csk_listen_stop() call.

Subject: [PATCH 0903/1375] netcp: fix regression in receive processing

A cleanup patch I did was unfortunately wrong and introduced
multiple serious bugs in the netcp rx processing, as indicated
by these correct gcc warnings:

drivers/net/ethernet/ti/netcp_core.c:776:14: warning: 'buf_ptr' may be used uninitialized in this function [-Wuninitialized]
drivers/net/ethernet/ti/netcp_core.c:687:14: warning: 'ptr' may be used uninitialized in this function [-Wuninitialized]

I have checked the patch once more and found that a call to
get_pkt_info() accidentally got removed in netcp_free_rx_desc_chain,
and netcp_process_one_rx_packet no longer retrieved the correct
buffer length. This patch should fix all the known problems,
but I did not test on real hardware.

Subject: [PATCH 0905/1375] 6lowpan: fix debugfs interface entry name

This patches moves the debugfs interface related register after
netdevice register. The function lowpan_dev_debugfs_init will use
"dev->name" which can be before register_netdevice a format string.
The function register_netdevice will evaluate the format string if
necessary and replace "dev->name" to the real interface name.

From 41837ca962ecb4ae7d98b00f94a51e737c8384ea Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Wed, 21 Oct 2015 09:00:07 +0300
Subject: [PATCH 0907/1375] iwlwifi: pcie: allow to pretend to have Tx CSUM for
 debug

Allow to configure the driver to pretend to have TX CSUM
offload support. This will be useful to test the TSO flows
that will come in further patches.
This configuration is disabled by default.

Subject: [PATCH 0908/1375] iwlwifi: mvm: prepare the code towards TSO
 implementation

Differentiate between the cases where the skb is a large
send and the other cases.
Advertise TSO even if, at this stage, skb_gso_segment will
be called and it will do all the work.

Subject: [PATCH 0910/1375] iwlwifi: clear ieee80211_tx_info->driver_data in

The transport will need to use the info->driver_data
pointers. Since the op_mode has this memory hot in cache,
clear it there.

Subject: [PATCH 0913/1375] ibmveth: consolidate kmalloc of array, memset 0 to
 kcalloc

This is an API consolidation only. The use of kmalloc + memset to 0
is equivalent to kcalloc in this case as it is allocating an array
of elements.

Subject: [PATCH 0914/1375] iwlwifi: pcie: build an A-MSDU using TSO core

When the op_mode sends an skb whose payload is bigger than
MSS, PCIe will create an A-MSDU out of it. PCIe assumes
that the skb that is coming from the op_mode can fit in one
A-MSDU. It is the op_mode's responsibility to make sure
that this guarantee holds.

Additional headers need to be built for the subframes.
The TSO core code takes care of the IP / TCP headers and
the driver takes care of the 802.11 subframe headers.

These headers are stored on a per-cpu page that is re-used
for all the packets handled on that same CPU. Each skb
holds a reference to that page and releases the page when
it is reclaimed. When the page gets full, it is released
and a new one is allocated.

Since any SKB that doesn't go through the fast-xmit path
of mac80211 will be segmented, we can assume here that the
packet is not WEP / TKIP and has a proper SNAP header.

Subject: [PATCH 0916/1375] iwlwifi: mvm: refactor the way fw_key_table is
 handled

Instead of keeping the fw_key_table bits set when the keys are removed
(i.e. in D3 entry or HW_RESTART flows), clear them and set them again
only when the keys have been successfully re-added.  This makes the
bitmask more closely tied to the actual firmware programming.

Firmware will support filtering multicast L3 packets.
The L3 filtering is configured by the WOWLAN_CONFIG command.
All flags should be enabled by default.
Older firmware is not affected as it does not look into
this field.

Subject: [PATCH 0920/1375] iwlwifi: mvm: add extended dwell time

When doing active scan on crowded channels we are likely to miss probe
responses due to collisions. To overcome this issue we use an extended
dwell time on channels 1, 6 and 11; this dwell time is set to 100.

In case of fragmented scan extended dwell time is the maximum out of
channel time - 44 msec. Fragmented active scan will be addressed later.

Extended dwell time isn't used in sched scan or p2p find.

Subject: [PATCH 0921/1375] iwlwifi: mvm: Add a station in monitor mode

Currently when creating a new vif in monitor mode the driver doesn't
allocate a specific station. This causes that in the situation that
tx traffic is injected, the tx queues are not scheduled,
with the result of a TFD queue hang.
Fix that by allocating a station and ensuring its tx queues
are scheduled.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=104591

Subject: [PATCH 0922/1375] iwlwifi: mvm: change iwl_mvm_get_key_sta_id() to
 return the station

The code in iwl_mvm_update_tkip_key() is now pretty much duplicated
with the code in iwl_mvm_get_key_sta_id() doing the station ID lookup
again after it was already done. Change iwl_mvm_get_key_sta_id() to
iwl_mvm_get_key_sta(), returning the mvm_sta pointer, to allow that
duplicate code to be removed.

These registers can help to debug PHY issues. Since this
adds a significant amount of work to the debug collection
phase, dump the periphery registers only if the firmware

Subject: [PATCH 0927/1375] iwlwifi: mvm: Change number of associated stations
 when station becomes associated

Currently, the number of associated stations gets updated when adding
a new station or removing it. This is incorrect as it's possible that
a station was inserted before it was associated
Fix this by increasing/decreasing ap_assoc_sta_count whenever
a station transitions in/out the associated state.

Subject: [PATCH 0928/1375] iwlwifi: update key params on d0i3 entrance/exit

In order to let the fw do offloading properly, we need
to provide various key data (e.g. PN).

Configure the params on d0i3 entrance, and update them
back on d0i3 exit.

Since d3 code is now called in d0i3 which requires runtime
pm only, make d3.0 depend on CONFIG_PM (rather than
CONFIG_PM_SLEEP), and add required #ifdefs and wrappers
where needed, so both CONFIG_PM=n and CONFIG_PM_RUNTIME=n
configurations will build correctly.

Subject: [PATCH 0932/1375] iwlwifi: bail out in case of bad trans state

In case of bad trans state (i.e. fw is not loaded) bail
out immediately instead of calling the trans, which might
not be fully initialized yet.

Also add WARN_ON_ONCE to help debugging where the errorneous
call is coming from.

Subject: [PATCH 0934/1375] fm10k: correctly pack TLV structures and explain
 reasoning

The TLV format for little endian structures is actually 4 byte aligned
copy. To this end, we need to add an additional __aligned(4) marker
along with __packed to ensure that these structures are actually 4 byte
aligned and packed correctly. Use of just __packed will not work as this
will result in 1byte alignment which is incorrect. Add a comment
explaining the reasoning behind why these structures need the special
treatment.

Subject: [PATCH 0935/1375] fm10k: Cleanup exception handling for changing
 queues

This patch is meant to cleanup the exception handling for the paths where
we reset the interrupts and then reconfigure them.  In all of these paths
we had very different levels of exception handling.  I have updated the
driver so that all of the paths should result in a similar state if we
fail.

Specifically the driver will now unload the mailbox interrupt, free the
queue vectors and MSI-X, and then detach the interface.

In addition for any of the PCIe related resets I have added a check with
the hw_ready function to just make sure the registers are in a readable
state prior to reopening the interface.

Subject: [PATCH 0936/1375] fm10k: use ether_addr_equal instead of memcmp

When comparing MAC addresses, use ether_addr_equal instead of memcmp to
ETH_ALEN length. Found and replaced using the following sed:

 sed -e 's/memcmp\x28\(.*\), ETH_ALEN\x29/!ether_addr_equal\x28\1\x29/'

Subject: [PATCH 0947/1375] RDS: don't pretend to use cpu notifiers

It looks like an attempt to use CPU notifier here which was never
completed. Nobody tried to wire it up completely since 2k9. So I unwind
this code and get rid of everything not required. Oh look! 19 lines were
removed while code still does the same thing.

Subject: [PATCH 0949/1375] net: tcp: deal with listen sockets properly in
 tcp_abort.

When closing a listen socket, tcp_abort currently calls
tcp_done without clearing the request queue. If the socket has a
child socket that is established but not yet accepted, the child
socket is then left without a parent, causing a leak.

Fix this by setting the socket state to TCP_CLOSE and calling
inet_csk_listen_stop with the socket lock held, like tcp_close
does.

Tested using net_test. With this patch, calling SOCK_DESTROY on a
listen socket that has an established but not yet accepted child
socket results in the parent and the child being closed, such
that they no longer appear in sock_diag dumps.

Subject: [PATCH 0952/1375] tcp: send_reset: test for non-NULL sk first

tcp_md5_do_lookup requires a full socket, so once we extend
_send_reset() to also accept timewait socket we would have to change

if (!sk && hash_location)

to something like

if ((!sk || !sk_fullsock(sk)) && hash_location) {
  ...
} else {
  (sk && sk_fullsock(sk)) tcp_md5_do_lookup()
}

Switch the two branches: check if we have a socket first, then
fall back to a listener lookup if we saw a md5 option (hash_location).

Subject: [PATCH 0953/1375] tcp: honour SO_BINDTODEVICE for TW_RST case too

Hannes points out that when we generate tcp reset for timewait sockets we
pretend we found no socket and pass NULL sk to tcp_vX_send_reset().

Make it cope with inet tw sockets and then provide tw sk.

This makes RSTs appear on correct interface when SO_BINDTODEVICE is used.

Packetdrill test case:
// want default route to be used, we rely on BINDTODEVICE
`ip route del 192.0.2.0/24 via 192.168.0.2 dev tun0`

0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
// test case still works due to BINDTODEVICE
0.001 setsockopt(3, SOL_SOCKET, SO_BINDTODEVICE, "tun0", 4) = 0
0.100...0.200 connect(3, ..., ...) = 0

0.100 > S 0:0(0) <mss 1460,sackOK,nop,nop>
0.200 < S. 0:0(0) ack 1 win 32792 <mss 1460,sackOK,nop,nop>
0.200 > . 1:1(0) ack 1

0.210 close(3) = 0

0.210 > F. 1:1(0) ack 1 win 29200
0.300 < . 1:1(0) ack 2 win 46

// more data while in FIN_WAIT2, expect RST
1.300 < P. 1:1001(1000) ack 1 win 46

// fails without this change -- default route is used
1.301 > R 1:1(0) win 0

Subject: [PATCH 0954/1375] cxgb4: Warn if device doesn't have enough PCI
 bandwidth

Check if the device get enough bandwidth from the entire PCI chain to
satisfy its capabilities. This patch determines the PCIe device's
bandwidth capabilities by reading its PCIe Link Capabilities registers
and then call the pcie_get_minimum_link function to ensure that the
adapter is hooked into a slot which is capable of providing the
necessary bandwidth capabilities.

Subject: [PATCH 0955/1375] cxgb4: get naming correct for iscsi queues

All the upper level protocols like rdma, iscsi have their own offload rx
queues, so instead of using the generic naming convention be specific
while naming them. Improves code readability

Subject: [PATCH 0958/1375] sfc: Retry MCDI after NO_EVB_PORT error on a VF

After reboot the vswitch configuration from the PF may not be
complete before the VF attempts to restore filters. In that
case we see NO_EVB_PORT errors from the MC. Retry up to a time
limit or until a different result is seen.

Subject: [PATCH 0959/1375] sfc: Handle MCDI proxy authorisation

For unprivileged functions operations can be authorised by an admin
function. Extra steps are introduced to the MCDI protocol in this
situation - the initial response from the MCDI tells us that the
operation has been deferred, and we must retry when told. We then
receive an event telling us to retry.

Note that this provides only the functionality for the unprivileged
functions, not the handling of the administrative side.

Subject: [PATCH 0960/1375] sfc: Make failed filter removal less noisy

There are situations - mostly reset related - where our view of the
filter table differs from the hardware. In this case we may try and
remove filters that aren't actually installed. This isn't that
interesting in most situations, so downgrade the logging.

* add a function indicating if an individual statistics
  is available on this device
* calculate at run time the sset_count.
* return strings based on the available statistics of the device

Subject: [PATCH 0968/1375] cxgb4/cxgb4vf: Update Ingress padding boundary
 values for T6 adapter

Ingress padding boundary values got changed for T6.
    T5: 0=32B 1=64B 2=128B 3=256B 4=512B 5=1024B 6=2048B 7=4096B
    T6: 0=8B  1=16B 2=32B  3=64B  4=128B 5=128B  6=256B  7=512B

Updating the driver to set the correct boundary values in SGE_CONTROL to
32B.
Also, need to take care of this fl alignment change when calculating the
next packet offset.

Updating Congestion Channel/Priority Map in Congestion Manager Context
for T6. In T6 port 0 is mapped to channel 0 and port 1 is mapped to
channel 1. For 2 port T4/T5 adapter, port 0 is mapped to channel 0,1 and
port 1 is mapped to channel 2,3

Subject: [PATCH 0972/1375] cxgb4: Update mps_tcam output to include T6 fields

In T6, MPS classification has a 512 deep TCAM to do the match lookup.
Each entry has 80x2b sets containing 48 bit MAC address, port number,
VLAN Valid/ID, VNI, lookup type (outer or inner packet header).
[71:48] bit locations are overloaded for outer vs. inner lookup types.

Subject: [PATCH 0977/1375] ip_tunnel: Move stats update to iptunnel_xmit()

By moving stats update into iptunnel_xmit(), we can simplify
iptunnel_xmit() usage. With this change there is no need to
call another function (iptunnel_xmit_stats()) to update stats
in tunnel xmit code path.

Subject: [PATCH 0978/1375] fsl/fman: Add FMan MURAM support

Add Frame Manager Multi-User RAM support.
This internal FMan memory block is used by the
FMan hardware modules, the management being made
through the generic allocator.

The FMan Internal memory, for example, is used for
allocating transmit and receive FIFOs.

Subject: [PATCH 0979/1375] fsl/fman: Add FMan support

Add the Data Path Acceleration Architecture Frame Manger Driver.
The FMan embeds a series of hardware blocks that implement a group
of Ethernet interfaces. This patch adds The FMan configuration,
initialization and runtime control routines.

The FMan driver supports several hardware versions
differentiated by things like:
	- Different type of MACs
	- Number of MAC and ports
	- Available resources
	- Different hardware errata

From 57ba4c9b56d898a955f95cb4091aeab28e902cac Mon Sep 17 00:00:00 2001
From: Igal Liberman <igal.liberman@freescale.com>
Date: Mon, 21 Dec 2015 02:21:27 +0200
Subject: [PATCH 0980/1375] fsl/fman: Add FMan MAC support

Add the Data Path Acceleration Architecture Frame Manger MAC support.
This patch adds The FMan MAC configuration, initialization and
runtime control routines.
This patch contains support for these types of MACs:
	- dTSEC: Three speed Ethernet controller (10/100/1000 Mbps)
	- tGEC: 10G Ethernet controller (10 Gbps)
	- mEMAC: Multi-rate Ethernet MAC (10/100/1000/10000 Mbps)
Different FMan revisions have different type and number of MACs.

+/* struct dtsec_cfg - dTSEC configuration
+ * Transmit half-duplex flow control, under software control for 10/100-Mbps
+ * half-duplex media. If set, back pressure is applied to media by raising
+ * carrier.
+ * halfdup_retransmit:
+ * Number of retransmission attempts following a collision.
+ * If this is exceeded dTSEC aborts transmission due to excessive collisions.
+ * The standard specifies the attempt limit to be 15.
+ * halfdup_coll_window:
+ * The number of bytes of the frame during which collisions may occur.
+ * The default value of 55 corresponds to the frame byte at the end of the
+ * standard 512-bit slot time window. If collisions are detected after this
+ * byte, the late collision event is asserted and transmission of current
+ * frame is aborted.
+ * tx_pad_crc:
+ * Pad and append CRC. If set, the MAC pads all ransmitted short frames and
+ * appends a CRC to every frame regardless of padding requirement.
+ * tx_pause_time:
+ * Transmit pause time value. This pause value is used as part of the pause
+ * frame to be sent when a transmit pause frame is initiated.
+ * If set to 0 this disables transmission of pause frames.
+ * preamble_len:
+ * Length, in bytes, of the preamble field preceding each Ethernet
+ * start-of-frame delimiter byte. The default value of 0x7 should be used in
+ * order to guarantee reliable operation with IEEE 802.3 compliant hardware.
+ * rx_prepend:
+ * Packet alignment padding length. The specified number of bytes (1-31)
+ * of zero padding are inserted before the start of each received frame.
+ * For Ethernet, where optional preamble extraction is enabled, the padding
+ * appears before the preamble, otherwise the padding precedes the
+ * layer 2 header.
+ *
+ * This structure contains basic dTSEC configuration and must be passed to
+ * init() function. A default set of configuration values can be
+ * obtained by calling set_dflts().

Subject: [PATCH 0982/1375] fsl/fman: Add FMan Port Support

Add the Data Path Acceleration Architecture Frame Manger Port Driver.
The FMan driver uses a module called "Port" to represent the physical
TX and RX ports.
Each FMan version has different number of physical ports.
This patch adds The FMan Port configuration, initialization and
runtime control routines for both TX and RX.

+ * The port is initialized aware of its type, but other functions on a port
+ * may be indifferent to its type. When necessary, the driver verifies

From 032c5e82847a2214c3196a90f0aeba0ce252de58 Mon Sep 17 00:00:00 2001
From: Thomas Falcon <tlfalcon@linux.vnet.ibm.com>
Date: Mon, 21 Dec 2015 11:26:06 -0600
Subject: [PATCH 0984/1375] Driver for IBM System i/p VNIC protocol

This is a new device driver for a high performance SR-IOV assisted virtual
network for IBM System p and IBM System i systems.  The SR-IOV VF will be
attached to the VIOS partition and mapped to the Linux client via the
hypervisor's VNIC protocol that this driver implements.

This driver is able to perform basic tx and rx, new features
and improvements will be added as they are being developed and tested.

Subject: [PATCH 0988/1375] bnxt_en: support hwrm_func_drv_unrgtr command

During remove_one, the driver should issue hwrm_func_drv_unrgtr
command to inform firmware that this function has been unloaded.
This is to let firmware keep track of driver present/absent state
when driver is gracefully unloaded. A keep alive timer is needed
later to keep track of driver state during abnormal shutdown.

Remove the unnecessary "if" statement before the "for" statement:

if (x) {

...
}

Also, change the ring free function to return void as it only returns 0.

Subject: [PATCH 0994/1375] bnxt_en: Check hardware resources before enabling
 NTUPLE.

The hardware resources required to enable NTUPLE varies depending on
how many rx channels are configured.  We need to make sure we have the
resources before we enable NTUPLE.  Add bnxt_rfs_capable() to do the
checking.

In addition, we need to do the same checking in ndo_fix_features().  As
the rx channels are changed using ethtool -L, we call
netdev_update_features() to make the necessary adjustment for NTUPLE.

Calling netdev_update_features() in netif_running() state but before
calling bnxt_open_nic() would be a problem.  To make this work,
bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for
the true hardware state instead of checking netif_running().

cmpl rings, rss contexts, stats contexts, vnics, after we have
divided them for the VFs.  Otherwise, subsequent ring changes on
the PF may not work correctly.

We adjust all max resources in struct bnxt_pf_info after they have been
assigned to the VFs.  There is no need to keep the separate
max_pf_tx_rings and max_pf_rx_rings.

When SR-IOV is disabled, we call bnxt_hwrm_func_qcaps() to restore the
max resources for the PF.

Subject: [PATCH 0997/1375] bnxt_en: Keep track of the ring group resource.

Newer firmware will return the ring group resource when we call
hwrm_func_qcaps().  To be compatible with older firmware, use the
number of tx rings as the number of ring groups if the older firmware
returns 0.  When determining how many rx rings we can support, take
the ring group resource in account as well in _bnxt_get_max_rings().
Divide and assign the ring groups to VFs.

Subject: [PATCH 1000/1375] netfilter: nf_tables: release objects on netns
 destruction

We have to release the existing objects on netns removal otherwise we
leak them. Chains are unregistered in first place to make sure no
packets are walking on our rules and sets anymore.

The object release happens by when we unregister the family via
nft_release_afinfo() which is called from nft_unregister_afinfo() from
the corresponding __net_exit path in every family.

Subject: [PATCH 1002/1375] netfilter: nf_tables: remove check against removal
 of inactive objects

The following sequence inside a batch, although not very useful, is
valid:

 add table foo
 ...
 delete table foo

This may be generated by some robot while applying some incremental
upgrade, so remove the defensive checks against this.

This patch keeps the check on the get/dump path by now, we have to
replace the inactive flag by introducing object generations.

Subject: [PATCH 1005/1375] NFC: digital: Add Type4A tags support

The definition of DIGITAL_PROTO_NFCA_RF_TECH is modified to support
ISO14443 Type4A tags. Without this change it is not possible to start
polling for ISO14443 Type4A tags from the initiator side.

+* STMicroelectronics : NFC Transceiver ST95HF
+
+ST NFC Transceiver is required to attach with SPI bus.
+ST95HF node should be defined in DT as SPI slave device of SPI
+master with which ST95HF transceiver is physically connected.
+The properties defined below are required to be the part of DT
+to include ST95HF transceiver into the platform.
+
+Required properties:
+===================
+- reg: Address of SPI slave "ST95HF transceiver" on SPI master bus.
+
+- compatible: should be "st,st95hf" for ST95HF NFC transceiver
+
+- spi-max-frequency: Max. operating SPI frequency for ST95HF
+	transceiver.
+
+- enable-gpio: GPIO line to enable ST95HF transceiver.
+
+- interrupt-parent : Standard way to specify the controller to which
+	ST95HF transceiver's interrupt is routed.
+
+- interrupts : Standard way to define ST95HF transceiver's out
+	interrupt.
+
+Optional property:
+=================
+- st95hfvin-supply : This is an optional property. It contains a
+	phandle to ST95HF transceiver's regulator supply node in DT.
+
+Example:
+=======
+spi@9840000 {
+	reg = <0x9840000 0x110>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+	cs-gpios = <&pio0 4>;
+	status = "okay";
+
+	st95hf@0{
+		reg = <0>;
+		compatible = "st,st95hf";
+		status = "okay";
+		spi-max-frequency = <1000000>;
+		enable-gpio = <&pio4 0>;
+		interrupt-parent = <&pio0>;
+		interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
+	};
+
+};

Subject: [PATCH 1021/1375] nfc: st21nfca: Add support for acpi probing for i2c
 device.

Add support for acpi probing.
SMO2100 is used for st21nfca

It has been tested with the following acpi node on Minnowboard Max:
Note: Remove uicc-present or ese-present Package if one them is not
supported.

Device (NFC1)
{
	Name (_ADR, Zero)  // _ADR: Address
	Name (_HID, "SMO2100")  // _HID: Hardware ID
	Name (_CID, "SMO2100")  // _CID: Compatible ID
	Name (_DDN, "SMO NFC")  // _DDN: DOS Device Name
	Name (_UID, One)  // _UID: Unique ID
	Name (_DSD, Package (0x02)
	{
		/* Device Properties for _DSD */
		ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
		Package (0x02)
		{
			Package (0x02) { "uicc-present", 1 },
			Package (0x02) { "ese-present", 1 }
		}
	})
	Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
	{
		Name (SBUF, ResourceTemplate ()
		{
			I2cSerialBus (0x0001, ControllerInitiated, 400000,
				      AddressingMode7Bit, "\\_SB.I2C7",
				      0x00, ResourceConsumer, ,)
			GpioInt (Edge, ActiveHigh, ExclusiveAndWake, PullNone, 0x0000,
				 "\\_SB.GPO2", 0x00, ResourceConsumer, ,)
			{       // Pin list
				0x0001
			}
			GpioIo (Exclusive, PullDefault, 0x0000, 0x0000, IoRestrictionOutputOnly,
				"\\_SB.GPO2", 0x00, ResourceConsumer, ,)
			{       // Pin list
				0x0002,
			}
		})
		Return (SBUF) /* \_SB_.I2C7.NFC1._CRS.SBUF */
	}
	Method (_STA, 0, NotSerialized)  // _STA: Status
	{
		Return (0x0F)
	}
}

In case of error, nci_hci_create_pipe() returns NCI_HCI_INVALID_PIPE,
and not a negative error code.

Subject: [PATCH 1040/1375] bpf: hash: use per-bucket spinlock

Both htab_map_update_elem() and htab_map_delete_elem() can be
called from eBPF program, and they may be in kernel hot path,
so it isn't efficient to use a per-hashtable lock in this two
helpers.

The per-hashtable spinlock is used for protecting bucket's
hlist, and per-bucket lock is just enough. This patch converts
the per-hashtable lock into per-bucket spinlock, so that
contention can be decreased a lot.

Subject: [PATCH 1047/1375] ixgbe: Clean up redundancy in hw_enc_features

Clean up minor redundancy in the setting of hw_enc_features that
makes it appears that X550 uniquely has more encapsulation features
than other devices. The driver only supports one more feature, so
make it look that way. No longer set NETIF_F_SG since that is set
by the register_netdev call. Thanks to Alex Duyck for noticing this
slight confusion.

X550 allows for up to 64 RSS queues, but the driver can have max
of 63 (-1 MSIX vector for link).

On systems with >= 64 CPUs the driver will set the redirection table
for all 64 queues which will result in packets being dropped.

Subject: [PATCH 1049/1375] ixgbe: Correct X550EM_x revision check

The X550EM_x revision check needs to check a value, not just a bit.
Use a mask and check the value. Also remove the redundant check
inside the ixgbe_enter_lplu_t_x550em, because it can only be called
when both the mac type and revision check pass.

Subject: [PATCH 1050/1375] ixgbe: Fix bugs in ixgbe_clear_vf_vlans()

When I had rewritten the code for ixgbe_clear_vf_vlans() it looks like I
had transitioned back and forth between using word as an offset and using
word as a register offset.  As a result I honestly don't see how the code
was working before other than the fact that resetting the VLANs on the VF
like didn't do much to clear them.

Another issue found is that the mask was using a divide instead of a
modulus.  As a result the mask bit was incorrectly being set to either bit
0 or 1 based on the value of the VF being tested.  As a result the wrong
VFs were having their VLANs cleared if they were enabled.

I have updated the code so that word represents the offset in the array.
This way we can use the modulus and xor operations and they will make sense
instead of being performed on a 4 byte aligned value.

I replaced the statement "(word % 2) ^ 1" with "~word % 2" in order to
reduce the line length as the line exceeded 80 characters with the register
name inserted.  The two should be equivalent so the change should be safe.

Subject: [PATCH 1054/1375] mwifiex: fix bug for wildcard-prefix wowlan pattern

Wildcard prefix bytes are ignored while downloading packet
pattern to firmware. As packet offset is not adjusted
accordingly firmware end up matching the pattern at wrong
offset. The packet offset is corrected in this patch.

Hostapd restart attempt will be failed in this case with device

Sometimes AP sends TDLS setup response as AMSDU packet.
As driver doesn't parse it and update peer station's 11n
capability in this case, AMPDU doesn't get setup.

This patch calls mwifiex_process_tdls_action_frame() in
AMSDU Rx path to fix the problem.

This driver has a number of errors in the module initialization. These
include the following:

Parameter msi_support is stored in two places - one is removed.
Paramters sw_crypto and disable_watchdog were never stored in the final
locations, nor were they initialized properly.

Subject: [PATCH 1066/1375] rtlwifi: rtl8723ae: Fix initialization of module
 parameters

This driver has some errors in the handling of module parameters. These
include missing initialization for parameters msi_support and
disable_watchdog. In addition, neither of these parameters nor sw_crypto
are transferred into the locations used by the driver. A final fix is
adding parameter msi to the module named and description macros.

This driver failed to copy parameters sw_crypto and disable_watchdog into
the locations actually used by the driver. In addition, msi_support was
initialized three times and one of them used the wrong variable. The
initialization of parameter int_clear was moved so that it is near that
of the rest of the parameters.

Subject: [PATCH 1079/1375] rtlwifi: rtl_pci: Fix kernel panic

In commit 38506ecefab9 (rtlwifi: rtl_pci: Start modification for new
drivers), a bug was introduced that causes a NULL pointer dereference.
As this bug only affects the infrequently used RTL8192EE and only under
low-memory conditions, it has taken a long time for the bug to show up.

The bug was reported on the linux-wireless mailing list and also at
https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/ as
bug #1527603 (kernel crashes due to rtl8192ee driver on ubuntu 15.10).

Subject: [PATCH 1080/1375] be2net: fix VF link state transition from disabled
 to auto

The VF link state setting transition from "disable" to "auto" does not work
due to a bug in SET_LOGICAL_LINK_CONFIG_V1 cmd in FW. This issue could not
be fixed in FW due to some backward compatibility issues it causes with
some released drivers. The issue has been fixed by introducing a new
version (v2) of the cmd from 10.6 FW onwards. In v2, to set the VF link
state to auto, both PLINK_ENABLE and PLINK_TRACK bits have to be set to 1.

The VF link state setting feature now works on Lancer chips too from
FW ver 10.6.315.0 onwards.

Subject: [PATCH 1082/1375] be2net: cleanup FW flash image related macro
 defines

Many constant definitions relating to the FW-image layout
(such as section offset values) were defined in decimal format rather than
hexa-decimal. This makes this part of the code un-readable. Also some
defines related to BE2 are labeld "g2" and defines related to BE3 are
labeled "g3".  This patch cleans up all of this to make this code more
readable.

Subject: [PATCH 1084/1375] be2net: log digital signature errors while flashing
 FW image

(based on a jumper setting on the adapter.) In this mode, the FW image when
flashed is authenticated with a digital signature. This patch logs
appropriate error messages and return a status to ethtool when errors
relating to FW image authentication occur.

Subject: [PATCH 1085/1375] be2net: remove a line of code that has no effect

This patch removes a line of code that changes adapter->recommended_prio
value followed by yet another assignment.
Also, the variable is used to store the vlan priority value that is already
shifted to the PCP bits position in the vlan tag format. Hence, the name of
this variable is changed to recommended_prio_bits.

Subject: [PATCH 1086/1375] be2net: remove unused error variables

eeh_error, fw_timeout, hw_error variables in the be_adapter structure are
not used anymore. An earlier patch that introduced adapter->err_flags to
store this information missed removing these variables.

Subject: [PATCH 1087/1375] be2net: fix port-res desc query of
 GET_PROFILE_CONFIG FW cmd

Commit 72ef3a88fa8e ("be2net: set pci_func_num while issuing
GET_PROFILE_CONFIG cmd") passed a specific pf_num while issuing a
GET_PROFILE_CONFIG cmd as FW returns descriptors for all functions when
pf_num is zero. But, when pf_num is set to a non-zero value, FW does not
return the Port resource descriptor.
This patch fixes this by setting pf_num to 0 while issuing the query cmd
and adds code to pick the correct NIC resource descriptor from the list of
descriptors returned by FW.

Fixes: 72ef3a88fa8e ("be2net: set pci_func_num while issuing
		     GET_PROFILE_CONFIG cmd")

Subject: [PATCH 1088/1375] be2net: support ethtool get-dump option

This patch adds support for ethtool's --get-dump option in be2net,
to retrieve FW dump. In the past when this option was not yet available,
this feature was supported via the --register-dump option as a workaround.
This patch removes support for FW-dump via --register-dump option as it is
now available via --get-dump option. Even though the
"ethtool --register-dump" cmd which used to work earlier, will now fail
with ENOTSUPP error, we feel it is not an issue as this is used only
for diagnostics purpose.

Subject: [PATCH 1090/1375] ethtool: Add phy statistics

Ethernet PHYs can maintain statistics, for example errors while idle
and receive errors. Add an ethtool mechanism to retrieve these
statistics, using the same model as MAC statistics.

Subject: [PATCH 1093/1375] bcma: use module_init for the main part of bus
 initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So far we were using fs_initcall. It was (and still is) needed because
struct bus_type has to be registered early. However main bus
initialization has to happen later as it requires SPROM which depends on
NVRAM which depends on mtd.
Solve it by using fs_initcall only for bus_register call and module_init
for the rest. It affects bcma only when built-in obviously.

This was tested with BCM4706 and BCM5357C0 (BCM47XX), BCM4708A0
(ARCH_BCM_5301X) and BCM43225 (PCIe card with bcma as module).

Subject: [PATCH 1094/1375] wlcore/wl18xx: fw logger over sdio

Enable the FW Logger to work over the SDIO interface in addition to over UART
interface. In the new design we use fw internal memory instead of packet ram
that was used in older (wl12xx) design. This change reduces the impact on TP
and stability.

A new event was added to notify fw logger is ready for reading. Dynamic
configuration to debugfs was added as well.

Subject: [PATCH 1097/1375] ath10k: wake up device before accessing registers

commit 1aaf8efba0ae ("ath10k: disable PCI PS for QCA988X
and QCA99X0") partially reverts pci soc powersave support added by
commit 77258d409ce4 ("ath10k: enable pci soc powersaving"). While
reverting the change, pci wake up function is called after accessing
pci registers instead of prior to access. The assumption is that chip
is woken up before accessing its registers.Though this change does not
fix any known issues, this might help to avoid unknown or low power
platform specific issues.

Subject: [PATCH 1101/1375] ieee802154: cc2520: Check CRC & add promiscuous

This patch adds checking the "CRC_OK" bit at the end of packets coming
from the CC2520 radio. It also adds support for putting the radio in
promiscuous mode (in which packets are not dropped if the CRC fails).
In promiscuous mode the AUTOCRC flag is cleared so that the driver can
pass the received CRC to the monitors.

The radio now defaults to frame filtering (checking that the destination
and PANID in the incoming packet matches the local node). This matches
the other 15.4 radios and is what a user would expect to be the default.

Other changes:

1. Adds LQI calculation
2. Makes #defines for relevant bit fields in CC2520 registers

Subject: [PATCH 1102/1375] netfilter: nft_limit: allow to invert matching
 criteria

This patch allows you to invert the ratelimit matching criteria, so you
can match packets over the ratelimit. This is required to support what
hashlimit does.

Subject: [PATCH 1103/1375] netfilter: nf_tables: add packet duplication to the
 netdev family

You can use this to duplicate packets and inject them at the egress path
of the specified interface. This duplication allows you to inspect
traffic from the dummy or any other interface dedicated to this purpose.

Subject: [PATCH 1104/1375] netfilter: nf_tables: add forward expression to the
 netdev family

You can use this to forward packets from ingress to the egress path of
the specified interface. This provides a fast path to bounce packets
from one interface to another specific destination interface.

Subject: [PATCH 1106/1375] Bluetooth: hci_bcm: move all Broadcom ACPI IDs to
 BCM HCI driver

The IDs should all be for Broadcom BCM43241 module, and
hci_bcm is now the proper driver for them. This removes one
of two different ways of handling PM with the module.

Subject: [PATCH 1111/1375] bnxt_en: Separate bnxt_{rx|tx}_ring_info structs
 from bnxt_napi struct.

Currently, an rx and a tx ring are always paired with a completion ring.
We want to restructure it so that it is possible to have a dedicated
completion ring for tx or rx only.

The bnxt hardware uses a completion ring for rx and tx events.  The driver
has to process the completion ring entries sequentially for the rx and tx
events.  Using a dedicated completion ring for rx only or tx only has these
benefits:

1. A burst of rx packets can cause delay in processing tx events if the
completion ring is shared.  If tx queue is stopped by BQL, this can cause
delay in re-starting the tx queue.

2. A completion ring is sized according to the rx and tx ring size rounded
up to the nearest power of 2.  When the completion ring is shared, it is
sized by adding the rx and tx ring sizes and then rounded to the next power
of 2, often with a lot of wasted space.

3. Using dedicated completion ring, we can adjust the tx and rx coalescing
parameters independently for rx and tx.

The first step is to separate the rx and tx ring structures from the
bnxt_napi struct.

In this patch, an rx ring and a tx ring will point to the same bnxt_napi
struct to share the same completion ring.  No change in ring assignment
and mapping yet.

Subject: [PATCH 1113/1375] bnxt_en: Re-structure ring indexing and mapping.

In order to support dedicated or shared completion rings, the ring
indexing and mapping are re-structured as below:

1. bp->grp_info[] array index is 1:1 with bp->bnapi[] array index and
completion ring index.

2. rx rings 0 to n will be mapped to completion rings 0 to n.

3. If tx and rx rings share completion rings, then tx rings 0 to m will
be mapped to completion rings 0 to m.

4. If tx and rx rings use dedicated completion rings, then tx rings 0 to
m will be mapped to completion rings n + 1 to n + m.

5. Each tx or rx ring will use the corresponding completion ring index
for doorbell mapping and MSIX mapping.

Subject: [PATCH 1116/1375] bnxt_en: Modify ethtool -l|-L to support combined
 or rx/tx rings.

The driver can support either all combined or all rx/tx rings.  The
default is combined, but the user can now select rx/tx rings.

Subject: [PATCH 1118/1375] sh_eth: remove EDMAC_BIG_ENDIAN

Commit  71557a37adb5 ("[netdrvr] sh_eth: Add SH7619 support") added support
for the big-endian EDMAC descriptors. However, it was never used and never
worked right until the recent driver  fixes. I think we now  can just remove
this support,  it was only burdening the driver from the start. It should be
easy to do without disturbing the SH platform code, at least for now...

Now that {cpu|edmac}_to_{edmac|cpu}() functions boiled down to the mere
{cpu|le32}_to_{le32|cpu}() calls, there's no need for these functions
anymore, so just get rid of them.

Subject: [PATCH 1120/1375] l2tp: rely on ppp layer for skb scrubbing

Since 79c441ae505c ("ppp: implement x-netns support"), the PPP layer
calls skb_scrub_packet() whenever the skb is received on the PPP
device. Manually resetting packet meta-data in the L2TP layer is thus
redundant.

Subject: [PATCH 1124/1375] udp: properly support MSG_PEEK with truncated
 buffers

Backport of this upstream commit into stable kernels :
89c22d8c3b27 ("net: Fix skb csum races when peeking")
exposed a bug in udp stack vs MSG_PEEK support, when user provides
a buffer smaller than skb payload.

In this case,
skb_copy_and_csum_datagram_iovec(skb, sizeof(struct udphdr),
                                 msg->msg_iov);
returns -EFAULT.

This bug does not happen in upstream kernels since Al Viro did a great
job to replace this into :
skb_copy_and_csum_datagram_msg(skb, sizeof(struct udphdr), msg);
This variant is safe vs short buffers.

For the time being, instead reverting Herbert Xu patch and add back
skb->ip_summed invalid changes, simply store the result of
udp_lib_checksum_complete() so that we avoid computing the checksum a
second time, and avoid the problematic
skb_copy_and_csum_datagram_iovec() call.

This patch can be applied on recent kernels as it avoids a double
checksumming, then backported to stable kernels as a bug fix.

Subject: [PATCH 1125/1375] net: make ip6tunnel_xmit definition conditional

Moving the caller of iptunnel_xmit_stats causes a build error in
randconfig builds that disable CONFIG_INET:

In file included from ../net/xfrm/xfrm_input.c:17:0:
../include/net/ip6_tunnel.h: In function 'ip6tunnel_xmit':
../include/net/ip6_tunnel.h:93:2: error: implicit declaration of function 'iptunnel_xmit_stats' [-Werror=implicit-function-declaration]
  iptunnel_xmit_stats(dev, pkt_len);

The reason is that the iptunnel_xmit_stats definition is hidden
inside #ifdef CONFIG_INET but the caller is not. We can change
one or the other to fix it, and this patch adds a second #ifdef
around ip6tunnel_xmit() to avoid seeing the invalid call.

Subject: [PATCH 1126/1375] fsl/fman: allow modular build

ARM allmodconfig fails because of the addition of the FMAN driver:

drivers/built-in.o: In function `dtsec_restart_autoneg':
binder.c:(.text+0x173328): undefined reference to `mdiobus_read'
binder.c:(.text+0x173348): undefined reference to `mdiobus_write'
drivers/built-in.o: In function `dtsec_config':
binder.c:(.text+0x173d24): undefined reference to `of_phy_find_device'
drivers/built-in.o: In function `init_phy':
binder.c:(.text+0x1763b0): undefined reference to `of_phy_connect'
drivers/built-in.o: In function `stop':
binder.c:(.text+0x176014): undefined reference to `phy_stop'
drivers/built-in.o: In function `start':
binder.c:(.text+0x176078): undefined reference to `phy_start'

The reason is that the driver uses PHYLIB, but that is a loadable
module here, and fman itself is built-in.

This patch makes it possible to configure fman as a module as well
so we don't change the status of PHYLIB in an allmodconfig kernel,
and it adds a 'select PHYLIB' statement to ensure that phylib is
always built-in when fman is.

The driver uses "builtin_platform_driver(fman_driver);", which means
it cannot be unloaded, but it's still possible to have it as a loadable
module that gets loaded once and never removed.

Also, remove the error messages in these two functions, as we already

Bridge port attributes are offloaded to hardware when invoked with SELF

Allow a user to change these attribute only when port is bridged and
initialize them correctly when joining or leaving a bridge.

Subject: [PATCH 1132/1375] soreuseport: define reuseport groups

struct sock_reuseport is an optional shared structure referenced by each
socket belonging to a reuseport group.  When a socket is bound to an
address/port not yet in use and the reuseport flag has been set, the
structure will be allocated and attached to the newly bound socket.
When subsequent calls to bind are made for the same address/port, the
shared structure will be updated to include the new socket and the
newly bound socket will reference the group structure.

Usually, when an incoming packet was destined for a reuseport group,
all sockets in the same group needed to be considered before a
dispatching decision was made.  With this structure, an appropriate
socket can be found after looking up just one socket in the group.

This shared structure will also allow for more complicated decisions to
be made when selecting a socket (eg a BPF filter).

This work is based off a similar implementation written by
Ying Cai <ycai@google.com> for implementing policy-based reuseport
selection.

From e32ea7e747271a0abcd37e265005e97cc81d9df5 Mon Sep 17 00:00:00 2001
From: Craig Gallek <kraig@google.com>

Subject: [PATCH 1133/1375] soreuseport: fast reuseport UDP socket selection

Include a struct sock_reuseport instance when a UDP socket binds to
a specific address for the first time with the reuseport flag set.
When selecting a socket for an incoming UDP packet, use the information
available in sock_reuseport if present.

This required adding an additional field to the UDP source address
equality function to differentiate between exact and wildcard matches.
The original use case allowed wildcard matches when checking for
existing port uses during bind.  The new use case of adding a socket
to a reuseport group requires exact address matching.

Performance test (using a machine with 2 CPU sockets and a total of
48 cores):  Create reuseport groups of varying size.  Use one socket
from this group per user thread (pinning each thread to a different
core) calling recvmmsg in a tight loop.  Record number of messages
received per second while saturating a 10G link.
  10 sockets: 18% increase (~2.8M -> 3.3M pkts/s)
  20 sockets: 14% increase (~2.9M -> 3.3M pkts/s)
  40 sockets: 13% increase (~3.0M -> 3.4M pkts/s)

This work is based off a similar implementation written by
Ying Cai <ycai@google.com> for implementing policy-based reuseport
selection.

From 538950a1b7527a0a52ccd9337e3fcd304f027f13 Mon Sep 17 00:00:00 2001
From: Craig Gallek <kraig@google.com>
Date: Mon, 4 Jan 2016 17:41:47 -0500
Subject: [PATCH 1134/1375] soreuseport: setsockopt SO_ATTACH_REUSEPORT_[CE]BPF

Expose socket options for setting a classic or extended BPF program
for use when selecting sockets in an SO_REUSEPORT group.  These options
can be used on the first socket to belong to a group before bind or
on any socket in the group after bind.

This change includes refactoring of the existing sk_filter code to
allow reuse of the existing BPF filter validation checks.

From 3ca8e4029969d40ab90e3f1ecd83ab1cadd60fbb Mon Sep 17 00:00:00 2001
From: Craig Gallek <kraig@google.com>
Date: Mon, 4 Jan 2016 17:41:48 -0500
Subject: [PATCH 1135/1375] soreuseport: BPF selection functional test

This program will build classic and extended BPF programs and
validate the socket selection logic when used with
SO_ATTACH_REUSEPORT_CBPF and SO_ATTACH_REUSEPORT_EBPF.

It also validates the re-programing flow and several edge cases.

Subject: [PATCH 1136/1375] Bluetooth: Change eir_has_data_type() to more
 generic eir_get_data()

To make the EIR parsing helper more general purpose, make it return
the found data and its length rather than just saying whether the data
was present or not.

Subject: [PATCH 1137/1375] Bluetooth: Add support for Start Limited Discovery
 command

This patch implements the mgmt Start Limited Discovery command. Most
of existing Start Discovery code is reused since the only difference
is the presence of a 'limited' flag as part of the discovery state.

Subject: [PATCH 1138/1375] sctp: add the rhashtable apis for sctp global
 transport hashtable

tranport hashtbale will replace the association hashtable to do the
lookup for transport, and then get association by t->assoc, rhashtable
apis will be used because of it's resizable, scalable and using rcu.

lport + rport + paddr will be the base hashkey to locate the chain,
with net to protect one netns from another, then plus the laddr to
compare to get the target.

this patch will provider the lookup functions:
- sctp_epaddr_lookup_transport
- sctp_addrs_lookup_transport

hash/unhash functions:
- sctp_hash_transport
- sctp_unhash_transport

init/destroy functions:
- sctp_transport_hashtable_init
- sctp_transport_hashtable_destroy

Subject: [PATCH 1139/1375] sctp: apply rhashtable api to send/recv path

apply lookup apis to two functions, for __sctp_endpoint_lookup_assoc
and __sctp_lookup_association, it's invoked in the protection of sock
lock, it will be safe, but sctp_lookup_association need to call
rcu_read_lock() and to detect the t->dead to protect it.

From b5eff7128366c4a7a9b502097a968ec9cae2bea2 Mon Sep 17 00:00:00 2001
From: Xin Long <lucien.xin@gmail.com>
Date: Wed, 30 Dec 2015 23:50:49 +0800
Subject: [PATCH 1141/1375] sctp: drop the old assoc hashtable of sctp

transport hashtable will replace the association hashtable,
so association hashtable is not used in sctp any more, so
drop the codes about that.

From ef9814deafd0c83a358d49e3709c3e16cc352118 Mon Sep 17 00:00:00 2001
From: Eran Ben Elisha <eranbe@mellanox.com>
Date: Tue, 29 Dec 2015 14:58:31 +0200
Subject: [PATCH 1145/1375] net/mlx5e: Add HW timestamping (TS) support

Add support for enable/disable HW timestamping for incoming and/or
outgoing packets. To enable/disable HW timestamping appropriate
ioctl should be used. Currently HWTSTAMP_FILTER_ALL/NONE and
HWTSAMP_TX_ON/OFF only are supported. Make all relevant changes in
RX/TX flows to consider TS request and plant HW timestamps into
relevant structures.

Add internal clock for converting hardware timestamp to nanoseconds. In
addition, add a service task to catch internal clock overflow, to make
sure timestamping is accurate.

Subject: [PATCH 1146/1375] net/mlx5e: Add PTP Hardware Clock (PHC) support

Add a PHC support to the mlx5_en driver. Use reader/writer spinlocks to
protect the timecounter since every packet received needs to call
timecounter_cycle2time() when timestamping is enabled.  This can become
a performance bottleneck with RSS and multiple receive queues if normal
spinlocks are used.

The driver has been tested with both Documentation/ptp/testptp and the
linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox
ConnectX-4 card.

Subject: [PATCH 1147/1375] include/uapi/linux/sockios.h: mark SIOCRTMSG unused

IOCTL SIOCRTMSG does nothing but return EINVAL.

So comment it as unused.

SIOCRTMSG is only used in:
* net/ipv4/af_inet.c
* include/uapi/linux/sockios.h

inet_ioctl calls ip_rt_ioctl.
ip_rt_ioctl only handles SIOCADDRT and SIOCDELRT and returns -EINVAL
otherwise.

gcc fails to see that the use of the 'last_offset' variable

drivers/net/ethernet/hisilicon/hns/hns_enet.c:541:6: warning: 'last_offset' may be used uninitialized in this function [-Wmaybe-uninitialized]

This simplifies the function to make it more obvious what is
going on to both readers and compilers, which makes the warning
go away.

Subject: [PATCH 1150/1375] mlxsw: pci: Adjust value of CPU egress traffic
 class

During initialization, when creating the send descriptor queues (SDQs),
we specify the CPU egress traffic class of each SDQ. The maximum number
of classes of this type is different in the two ASICs supported by this
PCI driver.

New firmware versions check this value is set correctly, which causes
errors on the Spectrum ASIC, as its max exposed egress traffic class is
lower than 7.

Solve this by setting this field to 3, which is an acceptable value for
both ASICs.

Note that we currently do not expose the QoS capabilities of the ASICs,
so setting this to an hardcoded value is OK for now.

Subject: [PATCH 1151/1375] soreuseport: pass skb to secondary UDP socket
 lookup

This socket-lookup path did not pass along the skb in question
in my original BPF-based socket selection patch.  The skb in the
udpN_lib_lookup2 path can be used for BPF-based socket selection just
like it is in the 'traditional' udpN_lib_lookup path.

udpN_lib_lookup2 kicks in when there are greater than 10 sockets in
the same hlist slot.  Coincidentally, I chose 10 sockets per
reuseport group in my functional test, so the lookup2 path was not
excersised. This adds an additional set of tests with 20 sockets.

Fixes: 538950a1b752 ("soreuseport: setsockopt SO_ATTACH_REUSEPORT_[CE]BPF")
Fixes: 3ca8e4029969 ("soreuseport: BPF selection functional test")

 'gap'

For gpio=0xff (wake up host through SDIO interface) case,
gap=0xff means no delay (same as gap=0) for incoming data packet
to be sent to host after host sleep is activated.
Change it to the maximum delay to reduce the chance that RX
interrupt could be delivered while host controller suspends.

Subject: [PATCH 1155/1375] Bluetooth: btmrvl: don't send data to firmware
 while processing suspend

Usually when driver sends data to firmware it receives TX_DONE
(DN_LD_HOST_INT_STATUS) interrupt from firmware right away.
It's also observed that some times the fireware could delay
sending DN_LD_HOST_INT_STATUS interrupt. If driver sends data to
firmware during suspend processing and the TX_DONE interrupt is
delayed, it may come back at wrong time when SDIO host driver is
in the middle of suspending.

Block any data from stack while suspending. Also skip sending
data that are already in driver tx_queue.

Don't purge the skb queue on suspend to avoid intermittent music
after system resumes from S3.

Subject: [PATCH 1164/1375] ethernet/atheros/alx: sanitize buffer sizing and
 padding

This is based on the work done by Przemek Rudy in bug 70761 at
bugzilla.kernel.org, but with some work done to disentagle and clarify
things a bit.

Similar to Przemek's work and other drivers, we're adding a padding of 16
here, but we're also disentangling mtu size calculations from max buffer
size calculations a bit, and adding ETH_HLEN to the value written into
ALX_MTU. Hopefully, with a bit more consistency and clarity, things behave
better here. Sadly, I can only test in my alx-driven E2200, which worked
just fine before this patch.

In comment #58 of bug 70761, Eugene A. Shatokhin reports that this patch
does help considerably for a ROSA Linux user of his with an AR8162 network
adapter when patched into a 4.1.x-based kernel, with several days of
normal operation where wired network previously wasn't usable without
setting MTU to 9000 as a work-around.

We checked "err" on the lines before so we know it's zero here.

These cause a static checker warning because checking known things can
indicate a bug.  Maybe there is a missing assignment or we are checking
the wrong variable.

Subject: [PATCH 1169/1375] net: Add eth_platform_get_mac_address() helper.

A repeating pattern in drivers has become to use OF node information
and, if not found, platform specific host information to extract the
ethernet address for a given device.

Currently this is done with a call to of_get_mac_address() and then
some ifdef'd stuff for SPARC.

Consolidate this into a portable routine, and provide the
arch_get_platform_mac_address() weak function hook for all
architectures to implement if they want.

Subject: [PATCH 1170/1375] batman-adv: Fix invalid read while copying
 bat_iv.bcast_own

batadv_iv_ogm_orig_del_if removes a part of the bcast_own which previously
belonged to the now removed interface. This is done by copying all data
which comes before the removed interface and then appending all the data
which comes after the removed interface.

The address calculation for the position of the data which comes after the
removed interface assumed that the bat_iv.bcast_own is a pointer to a
single byte datatype. But it is a pointer to unsigned long and thus the
calculated position was wrong off factor sizeof(unsigned long).

Fixes: 83a8342678a0 ("more basic routing code added (forwarding packets /
bitarray added)")

Subject: [PATCH 1175/1375] mwifiex: reduce cloned skb queue size

Driver supports Tx status ack feature. When hostapd/
wpa_supplicant asks for ack status of an EAPOL/ACTION
frame, driver maintains a cloned skb for the packet
until TX_STATUS event is received from firmware.

Cloned skb queue gets flushed when connection is terminated
or driver is unloaded.

Let's reduce the queue size to avoid unnecessarily
keeping memory allocated when environment is busy.

 command

Several features in the driver directly map to a firmware feature
listed in response of the 'cap' firmware command. For those features
this response will be examined instead of attempting individual
firmware commands.

Subject: [PATCH 1181/1375] brcmfmac: Fix warn trace on module unload while in
 ibss mode

When the driver is being unloaded a situation can occur where the
wirelesss core (cfg80211) wants to remove the ibss, but the state
of brcmfmac has already been set to down. When an error is
returned in that situation then that will result in a stack
trace on removal of the wiphy object. This is avoided by
returning 0 when device is down on a leave_ibss call.

Module parameters are defined in several files. Move them in one
place and make them device specific or global. This makes it
easier to override device specific settings by external data like
platform data in the future.

Subject: [PATCH 1183/1375] brcmfmac: introduce module parameter to force
 successful probe

The module parameter can be used to ensure the probe succeeds thus
claiming the device and allowing post-mortem debugging in case of
firmware crash. It is only available when select CONFIG_BRCMDBG.

From 7683fe016c010a20b5f2d88b7d8dad198506f5f7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1184/1375] rt2x00pci: Disable memory-write-invalidate when the
 driver exits

The driver calls pci_set_mwi to enable memory-write-invalidate when it
is initialized, but does not call pci_clear_mwi when it is removed. Many
other drivers calls pci_clear_mwi when pci_set_mwi is called, such as
r8169, 8139cp and e1000.

This patch adds pci_clear_mwi in error handling and removal procedure,
which can fix the problem.

Subject: [PATCH 1185/1375] ath10k: set SM power save disabled to default value
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use SMPS disabled as default because FW does not indicate
any support of SMPS.

This change will help STAs out that don’t support SMPS from
sticking on 1SS, since they don’t have method to change it
back to multiple chains.

This change also should not affect power consumption of STAs
supporting SMPS, because they are capable to switch the mode
to dynamic or static either at the end of frame sequence or
by using SMPS action frame.

When network interface is stopping, some resources may

Subject: [PATCH 1187/1375] wil6210: support for platform specific crash
 recovery

Added a simple interface for platform to perform crash
recovery.
When firmware crashes, wil driver can notify the platform
which can trigger a crash recovery process. During
the process the platform can request a ram dump
from the wil driver as well as control when firmware
recovery will start. This interface allows the platform
to implement a more advanced crash recovery, for
example to reset dependent subsystems in proper order, or
to provide its own notifications during the recovery process.

Subject: [PATCH 1188/1375] ath9k: Enable support for cloned SKBS

Ath9k driver does not modify tx skbs, so SUPPORTS_CLONED_SKBS
flag can be set. Enabling this flag significant reduce number
of copy operation during TCP Tx. This is especially noticeable
on platforms with slower CPU (lower CPU usage brings
profits in better TCP Tx troughput results).

Tested on MIPS with 560 MHz clock
Without CLONED_SKBS flag:
TCP Tx 145 Mb/s (iperf result)
__copy_user_common consumes 12.9% of CPU (result from perf tool)
0% CPU Idle

With CLONED_SKBS flag:
TCP Tx 170 Mb/s (iperf result)
__copy_user_common consumes 1.8% of CPU (result from perf tool)
12% CPU Idle

Subject: [PATCH 1190/1375] wcn36xx: handle rx skb allocation failure to avoid
 system crash

Lawrence reported that git clone could make system crash on a
Qualcomm ARM soc based device (DragonBoard, 1G memory without
swap) running 64bit Debian.

It's turned out the crash is related with rx skb allocation
failure. git could consume more than 600MB anonymous memory.
And system is in extremely memory shortage case.

But driver didn't handle the rx allocation failure case. This patch
doesn't submit skb to upper layer if rx skb allocation fails.
Instead, it reuse the old skb for rx DMA again. It's more like
drop the packets if system is in memory shortage case.

With this change, git clone is OOMed instead of system crash.

Subject: [PATCH 1192/1375] iwlwifi: dvm: fix WoWLAN

My commit below introduced a mutex in the transport to
prevent concurrent operations. To do so, it added a flag
(is_down) to make sure the transport is in the right state.
This uncoverred an bug that didn't cause any harm until
now: iwldvm calls stop_device and then starts the firmware
without calling start_hw in between. While this flow is
fine from the device configuration point of view (register,
etc...), it is now forbidden by the new is_down flag.
This led to this error to appear:
iwlwifi 0000:05:00.0: Can't start_fw since the HW hasn't been started
and the suspend would fail.

This fixes:

Subject: [PATCH 1194/1375] iwlwifi: mvm: let the firmware choose the antenna
 for beacons

The firmware knows better what antenna to choose.
Old firmware still need the setting, so use a flag to know
if the driver should choose the antenna or if the firmware
can do it iself.

Subject: [PATCH 1196/1375] iwlwifi: mvm: reset mvm->scan_type when firmware is
 started

If we don't reset the scan type when the firmware is
started, we will think the firmware is still configured
after the interface has been brought down. When we will
bring it up again, we will not configure the scan type
in firmware and it will crash with the following assert:

0x0000100A | ADVANCED_SYSASSERT

FW adds 10 msec for every dwell time in low band, so we need

Don't use extended dwell time when fragmented scan is needed
because FW adds 3 msec per probe and it can easily exceed
max out of channel time.

Subject: [PATCH 1202/1375] iwlwifi: mvm: add a non-trigger window to fw dbg
 triggers

Allow the user to configure a non-trigger session - a window
between triggers in which the driver won't collect fw debug data.
This can be useful when the frequent collection of fw data
has an impact on the performance, such as debugging
tx flows.

Since A-MPDU deaggregation is done in hardware, and A-MSDU deaggregation
is done in software, there's no reason not to support A-MSDU in A-MPDU;
set the flag to support it.

Subject: [PATCH 1205/1375] iwlwifi: mvm: prevent multiple stations with the
 same address

As the device (and parts of the driver) cannot deal with having the
same MAC address for two stations (on two virtual interfaces), add
some explicit code to prevent this case.

Note that in practice this cannot happen since the device doesn't
support operating with two AP/GO interfaces at the same time either,
and other scenarios for this are, while not impossible, not going to
happen in practice.

Subject: [PATCH 1206/1375] iwlwifi: mvm: don't ask beacons when P2P GO vif and
 no assoc sta

The commit below called iwl_mvm_mac_ctxt_changed() to handle
a case that the vif is a P2P GO.
However iwl_mvm_mac_ctxt_cmd_go() ignores the number of
associated stations and asks the FW to pass beacons anyways.

Fix this by checking ap_assoc_sta_count parameter, in iwl_mvm_mac_ctxt_cmd_go()
as well, and ask the FW to pass beacons only when there's
at least one associated station.

Subject: [PATCH 1207/1375] iwlwifi: mvm: check PN for CCMP/GCMP in the driver

As we're working on multi-queue RX, we want to parallelise checking
the PN in order to avoid having to serialise the RX processing.

It may seem that doing parallel PN checking is insecure, but it turns
out to be OK because queue assignment is done based on the data in the
frame (IP/TCP) and thus cannot be manipulated by an attacker, since
the data is encrypted and must first have been decrypted successfully.

There are some corner cases, in particular when the peer starts using
fragmentation which redirects the packet to the default queue. However
this redirection is remembered (for the STA, per TID) and thus cannot
be exploited by an attacker either.

Leave checking on the default queue (queue 0) to mac80211, since we
get fragmented packets there and those are subject to stricter checks
during reassembly.

This notification will be extended with extra data, so just
check that it has a minimum length, not the exact length;
we might later add handling for the extra fields added and
have more code to handle both versions.

Subject: [PATCH 1211/1375] iwlwifi: mvm: fix memory leaks in error paths upon
 fw error dump

When iwl_mvm_fw_error_dump fails, it needs to clear the
state in mvm, which includes:
	* clear IWL_MVM_STATUS_DUMPING_FW_LOG
	* set mvm->fw_dump_trig to NULL
	* free the description

While at it, remove a NULL check in
iwl_mvm_free_fw_dump_desc since kfree is NULL safe.

Subject: [PATCH 1212/1375] iwlwifi: pcie: properly configure the debug buffer
 size for 8000

8000 device family has a new debug engine that needs to be
configured differently than 7000's.
The debug engine's DMA works in chunks of memory and the
size of the buffer really means the start of the last
chunk. Since one chunk is 256-byte long, we should
configure the device to write to buffer_size - 256.
This fixes a situation were the device would write to
memory it is not allowed to access.

Subject: [PATCH 1213/1375] phy: Consistently use addr for address on an MII
 bus

Within phy.h, an address on an MII bus has been called both addr and
phy_id. phy_id is particularly confusion, since it also means the ID
found in register 3, if the device on the bus is a phy. Consistently
use addr.

From 2220943a21e26d97d7fd8f83c004b947326b469d Mon Sep 17 00:00:00 2001
From: Andrew Lunn <andrew@lunn.ch>
Date: Wed, 6 Jan 2016 20:11:13 +0100
Subject: [PATCH 1220/1375] phy: Centralise print about attached phy

Many Ethernet drivers contain the same netdev_info() print statement
about the attached phy. Move it into the phy device code. Additionally
add a varargs function which can be used to append additional
information.

Subject: [PATCH 1222/1375] mdio: Move allocation of interrupts into core

Have mdio_alloc() create the array of interrupt numbers, and
initialize it to POLLING. This is what most MDIO drivers want, so
allowing code to be removed from the drivers.

From e5a03bfd873c29eb786655ef2e95e53ed242b404 Mon Sep 17 00:00:00 2001
From: Andrew Lunn <andrew@lunn.ch>
Date: Wed, 6 Jan 2016 20:11:16 +0100
Subject: [PATCH 1223/1375] phy: Add an mdio_device structure

Not all devices attached to an MDIO bus are phys. So add an
mdio_device structure to represent the generic parts of an mdio
device, and place this structure into the phy_device.

Subject: [PATCH 1224/1375] of: phy: Only register a phy device for phys

We will soon support devices other than phys on the mdio bus. Look at
a child's compatibility string to determine if it is a phy, before
registering a phy device.

Subject: [PATCH 1225/1375] phy: Add API for {un}registering an mdio device to

Rather than have drivers directly manipulate the mii_bus structure,
provide and API for registering and unregistering devices on an MDIO

Subject: [PATCH 1226/1375] phy_device: Move phy attributes into phy_device

The mdio_bus exports three attributes:

- PHY ID is the unique 32-bits identifier for a MDIO device implementing
  standard MII registers MII_PHYSID1/2, which is not guaranteed to be the
  case for non-standard compliant devices (e.g: Ethernet switches)

- PHY interface describes the data-path of the PHY/MDIO device, which is
  not strictly a PHY thing, but is required and needed for PHY devices to
  function, a MDIO device could be a control device exclusively

- PHY has fixups describes what the PHY driver may have done, so
  completely PHY specific

These are all phy attributes, not generic mdio attributes. So move the
attributes into the phy device code.

When the phy is connected, an info message is printed. If the netdev
it is attached to has not been registered yet, the name
'uninitialised' in the output. By registering the netdev first, then
connecting they phy, we can avoid this.

The MDIO PM operations are really PHY device PM operations. So move
them into phy_device. This will be needed when we support devices on
the mdio bus which are not PHYs.

Rather than have each driver set the driver owner field, do it once in

Date: Wed, 6 Jan 2016 20:11:23 +0100
Subject: [PATCH 1230/1375] phy: Move phy specific bus match into phy_device

Matching a driver to a device has both generic parts, and parts which
are specific to PHY devices. Move the PHY specific parts into
phy_device.

Subject: [PATCH 1231/1375] mdio_bus: Generalise of_mdiobus_link_phydev()

This function should work with any sort of MDIO device which can be
probed on the bus, not just PHY devices. So generalise it.

Subject: [PATCH 1232/1375] mdio_bus: Add comment to mdiobus_scan() and
 __mdiobus_register()

Make it clear that mdiobus_scan () will only find devices which have a
vendor/product ID in registers 2 and 3. These are typically PHY
devices. Other sort of MDIO devices, such as switches, are not
expected to be found during the scan.

Similarly, __mdiobus_register(), which calls mdiobus_scan() will only
find PHY devices, and other sorts of MDIO devices are expected to be
instantiated from device tree.

Subject: [PATCH 1235/1375] net: ethernet: cadence-macb: Add disabled usrio
 caps

On some platforms, the macb integration does not use the USRIO
register to configure the (R)MII port and clocks.
When the register is not implemented and the MACB error signal
is connected to the bus error, reading or writing to the USRIO
register can trigger some Imprecise External Aborts on ARM platforms.

Subject: [PATCH 1241/1375] brcmfmac: change brcmf_sdio_wd_timer() prototype

The function brcmf_sdio_wd_timer() has wdtick parameter. However, it
is only called with two values and as such the parameter is replaced
with boolean value indicating the timer should be active or not.

From 63ce3d5db09324b56b739bfde5704799b0d6fd89 Mon Sep 17 00:00:00 2001
From: Arend van Spriel <arend@broadcom.com>
Date: Tue, 5 Jan 2016 11:05:48 +0100
Subject: [PATCH 1242/1375] brcmfmac: use msecs_to_jiffies() in macro
 definitions

Instead to having macro definition for millisecond timeout have
the definition directly in jiffies. This makes the unit of the
value immediately clear and may result in code that is bit more
compact.

Subject: [PATCH 1243/1375] brcmfmac: use jiffies for timeout in btcoex

The btcoex uses a timeout which was in milliseconds and got
converted to jiffies upon using timer api. Instead, convert
it to jiffies and treat it as such further.

Sometimes on module reload and reconnect to ibss a deauth from
other station can be received. This is treated as a link down but
for ibss this is wrong. It will close the interface and no data
is possible. Ignore the firmware generated link down events in
ibss mode, as ibss is always teared down by cfg80211.

Subject: [PATCH 1245/1375] i40e: change log messages and error returns

When VFs are being reset, there is a brief window of time when they
cannot be configured because they don't have a VSI to configure. If
a script is quick, it can fall through that window. To avoid
defenestration, log a useful error message and return -EAGAIN.

Allow the user to specify a zero MAC address for VFs. This removes the

Subject: [PATCH 1247/1375] i40e: Look up MAC address in Open Firmware or
 IDPROM

This is the i40e equivalent of commit c762dff24c06 ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").

As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.

In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.

The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.

Subject: [PATCH 1248/1375] i40e: Fix Rx hash reported to the stack by our
 driver

If the driver calls skb_set_hash even with a zero hash, that
indicates to the stack that the hash calculation is offloaded
in hardware. So the Stack doesn't do a SW hash which is required
for load balancing if the user decides to turn of rx-hashing
on our device.

This patch fixes the path so that we do not call skb_set_hash
if the feature is disabled.

Subject: [PATCH 1253/1375] ixgbe: do not call check_link for ethtool in
 ixgbe_get_settings()

In ixgbe_get_settings() the link status and speed of the interface
are determined based on a read from the LINKS register via the call
to mac.ops.check.link(). This can cause issues where external drivers
may end up with unknown speed when calling ethtool_get_setings().

Instead of calling the mac.ops.check_link() we can report the speed
from the adapter structure which is populated by the driver.

 setting

If an outer UDP checksum is set, pass the skb up with CHECKSUM_NONE
so that the stack will check the checksum. Do not increment an
error counter, because we don't know that there is an actual error.

Subject: [PATCH 1256/1375] ixgbe: Fix MDD events generated when FCoE+SRIOV are
 enabled

When FCoE is enabled with SR-IOV on the X550 NIC the hardware
generates MDD events.

This patch fixes these by setting the expected values in the
Tx context descriptors for FCoE/FIP frames and adding a flush
after writing the RDLEN register.

Subject: [PATCH 1257/1375] ixgbe: Make ATR recognize IPv6 extended headers

Right now ATR is not handling IPv6 extended headers, so ATR is not
being performed on such packets. Fix that by skipping extended
headers when they are present. This also fixes a problem where
the ATR code was not checking that the inner protocol was actually
TCP before setting up the signature rules. Since the protocol check
is intimately involved with the extended header processing as well,
this all gets fixed together.

 nft_set to store user data.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User data is stored at after 'nft_set_ops' private data into 'data[]'
flexible array. The field 'udata' points to user data and 'udlen' stores
its length.

Add new flag NFTA_SET_USERDATA.

Move the details behind the cb[] access into a small helper to decouple
and make them generic for bpf_prog_run_save_cb()/bpf_prog_run_clear_cb()
that was introduced via commit ff936a04e5f2 ("bpf: fix cb access in socket
filter programs"). Also add a comment to better clarify what is done in
bpf_skb_cb().

When the autosuspend is enabled and occurs before system suspend, we should
wake the device before running system syspend. Then, we could change the wake
event for system suspend. Otherwise, the device would resume the system when
receiving any packet.

Subject: [PATCH 1279/1375] batman-adv: purge bridge loop avoidance when its
 disabled

When bridge loop avoidance is disabled through sysfs, the internal
datastructures are not disabled, but only BLA operations are disabled.
To be sure that they are removed, purge the data immediately. That is
especially useful if a firmwares network state is changed, and the BLA
wait periods should restart on the new network.

Subject: [PATCH 1280/1375] batman-adv: increase BLA wait periods to 6

If networks take a long time to come up, e.g. due to lossy links, then
the bridge loop avoidance wait time to suppress broadcasts may not wait
long enough and detect a backbone before the mesh is brought up.
Increasing the wait period further to 60 seconds makes this scenario
less likely.

batadv_parse_gw_bandwidth. Move this functionality to its own function
batadv_parse_throughput to reduce the code complexity.

Subject: [PATCH 1283/1375] batman-adv: Delete unnecessary checks before the
 function call "kfree_skb"

The kfree_skb() function tests whether its argument is NULL and then
returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.

 batadv_tvlv_unicast_send()

* Let us return directly if a call of the batadv_orig_hash_find() function
  returned a null pointer.

* Omit the initialisation for the variable "skb" at the beginning.

* Replace an assignment by a call of the kfree_skb() function
  and delete the affected variable "ret" then.

Subject: [PATCH 1294/1375] vxlan: fix test which detect duplicate vxlan iface

When a vxlan interface is created, the driver checks that there is not
another vxlan interface with the same properties. To do this, it checks
the existing vxlan udp socket. Since commit 1c51a9159dde, the creation of
the vxlan socket is done only when the interface is set up, thus it breaks
that test.

Example:
$ ip l a vxlan10 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0
$ ip l a vxlan11 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0
$ ip -br l | grep vxlan
vxlan10          DOWN           f2:55:1c:6a:fb:00 <BROADCAST,MULTICAST>
vxlan11          DOWN           7a:cb:b9:38:59:0d <BROADCAST,MULTICAST>

Instead of checking sockets, let's loop over the vxlan iface list.

just pass local_port. This is needed in case this is called from SFN
process function and mlxsw_sp_port is not existent for particular

Subject: [PATCH 1296/1375] mlxsw: spectrum: remove FDB entry in case we get
 unknown object notification

It may happen that we get notification for FDB entry for object (port,
lag, vport), which does not exist. Currently we ignore that, which only
causes this being re-sent in next notification. The entry will never
disappear. So get rid of it by simply removing it using SFD register.

 IGMP Snooping
 ^^^^^^^^^^^^^
 
-XXX: complete this section
-
+In order to support IGMP snooping, the port netdevs should trap to the bridge
+driver all IGMP join and leave messages.
+The bridge multicast module will notify port netdevs on every multicast group
+changed whether it is static configured or dynamically joined/leave.
+The hardware implementation should be forwarding all registered multicast
+traffic groups only to the configured ports.

Subject: [PATCH 1305/1375] udp: restrict offloads to one namespace

udp tunnel offloads tend to aggregate datagrams based on inner
headers. gro engine gets notified by tunnel implementations about
possible offloads. The match is solely based on the port number.

Imagine a tunnel bound to port 53, the offloading will look into all
DNS packets and tries to aggregate them based on the inner data found
within. This could lead to data corruption and malformed DNS packets.

While this patch minimizes the problem and helps an administrator to find
the issue by querying ip tunnel/fou, a better way would be to match on
the specific destination ip address so if a user space socket is bound
to the same address it will conflict.

Subject: [PATCH 1306/1375] ipv4: Namespaceify tcp_keepalive_time sysctl knob

Different net namespaces might have different requirements as to
the keepalive time of tcp sockets. This might be required in cases
where different firewall rules are in place which require tcp
timeout sockets to be increased/decreased independently of the host.

Subject: [PATCH 1310/1375] bpf: add skb_postpush_rcsum and fix dev_forward_skb
 occasions

Add a small helper skb_postpush_rcsum() and fix up redirect locations
that need CHECKSUM_COMPLETE fixups on ingress. dev_forward_skb() expects
a proper csum that covers also Ethernet header, f.e. since 2c26d34bbcc0
("net/core: Handle csum for CHECKSUM_COMPLETE VXLAN forwarding"), we
also do skb_postpull_rcsum() after pulling Ethernet header off via
eth_type_trans().

When using eBPF in a netns setup f.e. with vxlan in collect metadata mode,
I can trigger the following csum issue with an IPv6 setup:

  [  505.144065] dummy1: hw csum failure

  [  505.144259]  [<ffffffff8160c4a5>] net_rx_action+0x145/0x320
  [...]

What happens is that on ingress, we push Ethernet header back in, either
from cls_bpf or right before skb_do_redirect(), but without updating csum.
The "hw csum failure" can be fixed by using the new skb_postpush_rcsum()
helper for the dev_forward_skb() case to correct the csum diff again.

Thanks to Hannes Frederic Sowa for the csum_partial() idea!

Subject: [PATCH 1313/1375] stmmac: Don't exit mdio registration when mdio
 subnode is not found in the DTS

Originally, most of the platforms using this driver did not define an mdio subnode
in the devicetree. Commit e34d65 ("stmmac: create of compatible mdio bus for stmmac driver")
introduced a backward compatibily issue by using of_mdiobus_register explicitly
with an mdio subnode. This patch fixes the issue by calling the function
mdiobus_register, when mdio subnode is not found. The driver is now compatible
with both modes.

Subject: [PATCH 1315/1375] net: ethernet-rgmii.c: Fix breakage from moving
 phdev bus

The mdio device patches moved the bus member in phy_device into a
substructure. This driver got missed. Fix it.

Subject: [PATCH 1316/1375] net: ethernet: broadcom: Fix build errors

Commit 7f854420fbfe ("phy: Add API for {un}registering an mdio device to
a bus") introduces an API to access mii_bus structures, but missed to
update the sb1250 driver. This results in the following build error.

drivers/net/ethernet/broadcom/sb1250-mac.c: In function 'sbmac_mii_probe':
drivers/net/ethernet/broadcom/sb1250-mac.c:2360:24: error:
	'struct mii_bus' has no member named 'phy_map'

Use phy_find_first() instead of open coding it.

Commit 2220943a21e2 ("phy: Centralise print about attached phy") introduces
the following build error.

drivers/net/ethernet/broadcom/sb1250-mac.c: In function 'sbmac_mii_probe':
drivers/net/ethernet/broadcom/sb1250-mac.c:2383:20: error: 'phydev' undeclared

Subject: [PATCH 1320/1375] net, sched: add clsact qdisc

This work adds a generalization of the ingress qdisc as a qdisc holding
only classifiers. The clsact qdisc works on ingress, but also on egress.
In both cases, it's execution happens without taking the qdisc lock, and
the main difference for the egress part compared to prior version of [1]
is that this can be applied with _any_ underlying real egress qdisc (also
classless ones).

Besides solving the use-case of [1], that is, allowing for more programmability
on assigning skb->priority for the mqprio case that is supported by most
popular 10G+ NICs, it also opens up a lot more flexibility for other tc
applications. The main work on classification can already be done at clsact
egress time if the use-case allows and state stored for later retrieval
f.e. again in skb->priority with major/minors (which is checked by most
classful qdiscs before consulting tc_classify()) and/or in other skb fields
like skb->tc_index for some light-weight post-processing to get to the
eventual classid in case of a classful qdisc. Another use case is that
the clsact egress part allows to have a central egress counterpart to
the ingress classifiers, so that classifiers can easily share state (e.g.
in cls_bpf via eBPF maps) for ingress and egress.

Currently, default setups like mq + pfifo_fast would require for this to
use, for example, prio qdisc instead (to get a tc_classify() run) and to
duplicate the egress classifier for each queue. With clsact, it allows
for leaving the setup as is, it can additionally assign skb->priority to
put the skb in one of pfifo_fast's bands and it can share state with maps.
Moreover, we can access the skb's dst entry (f.e. to retrieve tclassid)
w/o the need to perform a skb_dst_force() to hold on to it any longer. In
lwt case, we can also use this facility to setup dst metadata via cls_bpf
(bpf_skb_set_tunnel_key()) without needing a real egress qdisc just for
that (case of IFF_NO_QUEUE devices, for example).

The realization can be done without any changes to the scheduler core
framework. All it takes is that we have two a-priori defined minors/child
classes, where we can mux between ingress and egress classifier list
(dev->ingress_cl_list and dev->egress_cl_list, latter stored close to
dev->_tx to avoid extra cacheline miss for moderate loads). The egress
part is a bit similar modelled to handle_ing() and patched to a noop in
case the functionality is not used. Both handlers are now called
sch_handle_ingress() and sch_handle_egress(), code sharing among the two
doesn't seem practical as there are various minor differences in both
paths, so that making them conditional in a single handler would rather
slow things down.

Full compatibility to ingress qdisc is provided as well. Since both
piggyback on TC_H_CLSACT, only one of them (ingress/clsact) can exist
per netdevice, and thus ingress qdisc specific behaviour can be retained
for user space. This means, either a user does 'tc qdisc add dev foo ingress'
and configures ingress qdisc as usual, or the 'tc qdisc add dev foo clsact'
alternative, where both, ingress and egress classifier can be configured
as in the below example. ingress qdisc supports attaching classifier to any
minor number whereas clsact has two fixed minors for muxing between the
lists, therefore to not break user space setups, they are better done as
two separate qdiscs.

I decided to extend the sch_ingress module with clsact functionality so
that commonly used code can be reused, the module is being aliased with
sch_clsact so that it can be auto-loaded properly. Alternative would have been
to add a flag when initializing ingress to alter its behaviour plus aliasing
to a different name (as it's more than just ingress). However, the first would
end up, based on the flag, choosing the new/old behaviour by calling different
function implementations to handle each anyway, the latter would require to
register ingress qdisc once again under different alias. So, this really begs
to provide a minimal, cleaner approach to have Qdisc_ops and Qdisc_class_ops
by its own that share callbacks used by both.

Example, adding qdisc:

   # tc qdisc add dev foo clsact
   # tc qdisc show dev foo
   qdisc mq 0: root
   qdisc pfifo_fast 0: parent :1 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
   qdisc pfifo_fast 0: parent :2 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
   qdisc pfifo_fast 0: parent :3 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
   qdisc pfifo_fast 0: parent :4 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
   qdisc clsact ffff: parent ffff:fff1

Adding filters (deleting, etc works analogous by specifying ingress/egress):

   # tc filter add dev foo ingress bpf da obj bar.o sec ingress
   # tc filter add dev foo egress  bpf da obj bar.o sec egress
   # tc filter show dev foo ingress
   filter protocol all pref 49152 bpf
   filter protocol all pref 49152 bpf handle 0x1 bar.o:[ingress] direct-action
   # tc filter show dev foo egress
   filter protocol all pref 49152 bpf
   filter protocol all pref 49152 bpf handle 0x1 bar.o:[egress] direct-action

A 'tc filter show dev foo' or 'tc filter show dev foo parent ffff:' will
show an empty list for clsact. Either using the parent names (ingress/egress)
or specifying the full major/minor will then show the related filter lists.

Prior work on a mqprio prequeue() facility [1] was done mainly by John Fastabend.

For future compatibility, zero pad all messages that the driver sends
to the firmware to 128 bytes.  If these messages are extended in the
future with new byte enables, zero padding these messages now will
guarantee future compatibility.

Subject: [PATCH 1324/1375] net: ethernet: arc: Keep emac compatibility for
 more Rockchip SoCs

On the RK3066/RK3188, there was fixed GRF offset configuration to set emac
and fixed DIV2 mac TX/RX clock. So, we need to easily set and fit to other
SoCs (RK3036) which maybe have different GRF offset, and need adjust mac
TX/RX clock.

Really the kernel should take care of this by using cond_resched(),

Subject: [PATCH 1334/1375] net: tc35815: Fix build error due to missed API
 change

Commit 7f854420fbfe ("phy: Add API for {un}registering an mdio device to
a bus") introduces an API to access mii_bus structures, but missed to
update the tc35815 driver. This results in the following error message.

drivers/net/ethernet/toshiba/tc35815.c: In function 'tc_mii_probe':
drivers/net/ethernet/toshiba/tc35815.c:617:18: error:
	'struct mii_bus' has no member named 'phy_map'
drivers/net/ethernet/toshiba/tc35815.c:623:24: error:
	'struct mii_bus' has no member named 'phy_map'

Instead of looping over the list of phy addresses to find a phy chip,
use phy_find_first(). While the intent of the original code was to return
an error if more than one phy was specified, this code path was never
executed because the loop aborted after finding the first phy. The
original code is therefore semantically identical to phy_find_first(),
thus it is simpler and more straightforward to use phy_find_first()
directly.

commit 6b001e682e90 ("openvswitch: Use Geneve device.")

The commit above introduced 'port_no' as the name for the member of
struct geneve_port. The correct name should be 'dst_port' as described
in the kernel doc. Let's fix that member name and all the pertinent
instances so that both doc and code would be consistent.

Subject: [PATCH 1341/1375] unix: properly account for FDs passed over unix
 sockets

It is possible for a process to allocate and accumulate far more FDs than
the process' limit by sending them over a unix socket then closing them
to keep the process' fd count low.

This change addresses this problem by keeping track of the number of FDs
in flight per user and preventing non-privileged processes from having
more FDs in flight than their configured FD limit.

Subject: [PATCH 1342/1375] mlxsw: spectrum: Add FDB lock to prevent session
 interleaving

Dumping the FDB (invoked with a process context) or handling FDB
notifications (polled periodicly in delayed work) might each entail
multiple EMAD transcations due to the number of entries.

While we only allow one EMAD transaction at a time, there is nothing
stopping the dump and notification processing sessions from
interleaving. However, this is forbidden by the hardware, so we need to
make sure only one of these sessions can run at a time.

Solve this by adding a mutex ('fdb_lock'), as both kernel threads can
sleep while waiting for the response EMAD.

Subject: [PATCH 1344/1375] sctp: fix use-after-free in pr_debug statement

Dmitry Vyukov reported a use-after-free in the code expanded by the
macro debug_post_sfx, which is caused by the use of the asoc pointer
after it was freed within sctp_side_effect() scope.

This patch fixes it by allowing sctp_side_effect to clear that asoc
pointer when the TCB is freed.

As Vlad explained, we also have to cover the SCTP_DISPOSITION_ABORT case
because it will trigger DELETE_TCB too on that same loop.

Also, there were places issuing SCTP_CMD_INIT_FAILED and ASSOC_FAILED
but returning SCTP_DISPOSITION_CONSUME, which would fool the scheme
above. Fix it by returning SCTP_DISPOSITION_ABORT instead.

The macro is already prepared to handle such NULL pointer.

Subject: [PATCH 1345/1375] bonding: make mii_status sysfs node consistent

The spew in /proc/net/bonding/bond0 uses netif_carrier_ok() to determine
mii_status, while /sys/class/net/bond0/bonding/mii_status looks at
curr_active_slave, which doesn't actually seem to be set sometimes when
the bond actually is up. A mode 4 bond configured via ifcfg-foo files on a
Red Hat Enterprise Linux system, after boot, comes up clean and
functional, but the sysfs node shows mii_status of down, while proc shows
up. A simple enough fix here seems to be to use the same method for
determining up or down in both places, and I'd opt for the one that seems
to match reality.

Subject: [PATCH 1346/1375] tcp_yeah: don't set ssthresh below 2

For tcp_yeah, use an ssthresh floor of 2, the same floor used by Reno
and CUBIC, per RFC 5681 (equation 4).

tcp_yeah_ssthresh() was sometimes returning a 0 or negative ssthresh
value if the intended reduction is as big or bigger than the current
cwnd. Congestion control modules should never return a zero or
negative ssthresh. A zero ssthresh generally results in a zero cwnd,
causing the connection to stall. A negative ssthresh value will be
interpreted as a u32 and will set a target cwnd for PRR near 4
billion.

Oleksandr Natalenko reported that a system using tcp_yeah with ECN
could see a warning about a prior_cwnd of 0 in
tcp_cwnd_reduction(). Testing verified that this was due to
tcp_yeah_ssthresh() misbehaving in this way.

Export flags used by eBPF helper functions through UAPI, so they can be
used by programs (instead of them redefining all flags each time or just
using the hard-coded values). It also gives a better overview what flags
are used where and we can further get rid of the extra macros defined in
filter.c. Moreover, reject invalid flags.

Subject: [PATCH 1351/1375] bpf: support ipv6 for bpf_skb_{set,get}_tunnel_key

After IPv6 support has recently been added to metadata dst and related
encaps, add support for populating/reading it from an eBPF program.

Commit d3aa45ce6b ("bpf: add helpers to access tunnel metadata") started
with initial IPv4-only support back then (due to IPv6 metadata support
not being available yet).

To stay compatible with older programs, we need to test for the passed
structure size. Also TOS and TTL support from the ip_tunnel_info key has
been added. Tested with vxlan devs in collect meta data mode with IPv4,
IPv6 and in compat mode over different network namespaces.

Subject: [PATCH 1353/1375] udp: disallow UFO for sockets with SO_NO_CHECK
 option

Commit acf8dd0a9d0b ("udp: only allow UFO for packets from SOCK_DGRAM
sockets") disallows UFO for packets sent from raw sockets. We need to do
the same also for SOCK_DGRAM sockets with SO_NO_CHECK options, even if
for a bit different reason: while such socket would override the
CHECKSUM_PARTIAL set by ip_ufo_append_data(), gso_size is still set and
bad offloading flags warning is triggered in __skb_gso_segment().

In the IPv6 case, SO_NO_CHECK option is ignored but we need to disallow
UFO for packets sent by sockets with UDP_NO_CHECK6_TX option.

Subject: [PATCH 1354/1375] net/mlx5_core: Introduce flow steering autogrouped
 flow table

When user add rule to autogrouped flow table, we search
for flow group with the same match criteria, if we don't
find such group then we create new flow group with the
required match criteria and insert the rule to this group.

We divide the flow table into required_groups + 1,
in order to reserve a part of the flow table for rules
which don't match any existing group.

Subject: [PATCH 1355/1375] net/mlx5_core: Add utilities to find next and prev
 flow-tables

Add two utility functions for find next and prev flow table.
Find next flow table function gets priority and return the
first flow table of the next priority in the tree.
Find prev flow table return the last flow table of
the previous priority in the tree.

These utility functions are used for chaining flow table from different
priorities.

Subject: [PATCH 1356/1375] net/mlx5_core: Managing root flow table

The root Flow Table for each Flow Table Type is defined,
by default, as the Flow Table with level 0.

In order not to use an empty flow tables and introduce new hops,
but still preserve space for flow-tables that have a priority
greater(lower number) than the current flow table, we introduce this
new set root flow table command.
This command tells the HW to start matching packets from the
assigned root flow table.
This command is used when we create new flow table with level lower than the
current lowest flow table or it is the first flow table.

Subject: [PATCH 1357/1375] net/mlx5_core: Introduce modify flow table command

Introduce the modify flow table command. This command is used when
we want to change the next flow table of an existing flow table.
The next flow table is defined as the table we search (in order
to find a match), if we couldn't find a match in any of the flow table
entries in the current flow table.

Subject: [PATCH 1358/1375] net/mlx5_core: Connect flow tables

Flow tables from different priorities should be chained together.
When a packet arrives we search for a match in the
by-pass flow tables (first we search for a match in priority 0
and if we don't find a match we move to the next priority).
If we can't find a match in any of the bypass flow-tables, we continue
searching in the flow-tables of the next priority, which are the
kernel's flow tables.

Setting the miss flow table in a new flow table to be the next one in
the list is performed via create flow table API. If we want to change an
existing flow table, for example in order to point from an
existing flow table to the new next-in-list flow table, we use the
modify flow table API.

Subject: [PATCH 1359/1375] net/mlx5_core: Set priority attributes

Each priority has two attributes:
1. max_ft - maximum allowed flow tables under this priority.
2. start_level - start level range of the flow tables
in the priority.

These attributes are set by traversing the tree nodes by
DFS and set start level and max flow tables to each priority.
Start level depends on the max flow tables of the prior priorities
in the tree.

The leaves of the trees have max_ft set in them. Each node accumulates
the max_ft of its children and set it accordingly.

Subject: [PATCH 1361/1375] net/mlx5_core: Enable flow steering support for the
 IB driver

When the driver is loaded, we create flow steering namespace
for kernel bypass with nine priorities and another namespace
for leftovers(in order to catch packets that weren't matched).
Verbs applications will use these priorities.
we found nine as a number that balances the requirements from the
user and retains performance.

The bypass namespace is used by verbs applications that want to bypass
the kernel networking stack. The leftovers namespace is used by verbs
applications and the sniffer in order to catch packets that weren't
handled by any preceding rules.

Subject: [PATCH 1363/1375] net/mlx5_core: Export flow steering API

Add exports to flow steering API for mlx5_ib usage.
The following functions are exported:

1. mlx5_create_auto_grouped_flow_table - used to create flow
table with auto flow grouping management (create and destroy
flow groups). In auto-grouped flow tables, we create groups
automatically if needed (if we don't find an existing
flow group with same match criteria when we add new rule).

2. mlx5_destroy_flow_table - used to destroy  a flow table.

3. mlx5_add_flow_rule - used to add flow rule into a flow table.

4. mlx5_del_flow_rule - used to delete flow rule from its flow table.

5. mlx5_get_flow_namespace - used to get a handle to the required
namespace sub-tree.

Subject: [PATCH 1364/1375] IB/mlx5: Add flow steering support

Adding flow steering support by creating a flow-table per
priority (if rules exist in the priority). mlx5_ib uses
autogrouping and thus only creates the required destinations.

Also includes adding of these flow steering utilities

1. Parsing verbs flow attributes hardware steering specs.

2. Check if flow is multicast - this is required in order to decide
to which flow table will we add the steering rule.

3. Set outer headers in flow match criteria to zeros.

Subject: [PATCH 1365/1375] bonding: Prevent IPv6 link local address on
 enslaved devices

Commit 1f718f0f4f97 ("bonding: populate neighbour's private on enslave")
undoes the fix provided by commit c2edacf80e15 ("bonding / ipv6: no addrconf
for slaves separately from master") by effectively setting the slave flag
after the slave has been opened.  If the slave comes up quickly enough, it
will go through the IPv6 addrconf before the slave flag has been set and
will get a link local IPv6 address.

In order to ensure that addrconf knows to ignore the slave devices on state
change, set IFF_SLAVE before dev_open() during bonding enslavement.

Subject: [PATCH 1373/1375] phonet: properly unshare skbs in phonet_rcv()

Ivaylo Dimitrov reported a regression caused by commit 7866a621043f
("dev: add per net_device packet type chains").

skb->dev becomes NULL and we crash in __netif_receive_skb_core().

Before above commit, different kind of bugs or corruptions could happen
without major crash.

But the root cause is that phonet_rcv() can queue skb without checking
if skb is shared or not.

Many thanks to Ivaylo Dimitrov for his help, diagnosis and tests.

Subject: [PATCH 1374/1375] net: bpf: reject invalid shifts

On ARM64, a BUG() is triggered in the eBPF JIT if a filter with a
constant shift that can't be encoded in the immediate field of the
UBFM/SBFM instructions is passed to the JIT.  Since these shifts
amounts, which are negative or >= regsize, are invalid, reject them in
the eBPF verifier and the classic BPF filter checker, for all
architectures.

Subject: [PATCH 1375/1375] net: bnxt: always return values from
 _bnxt_get_max_rings

Newly added code in the bnxt driver uses a couple of variables that
are never initialized when CONFIG_BNXT_SRIOV is not set, and gcc
correctly warns about that:

In file included from include/linux/list.h:8:0,
                 from include/linux/module.h:9,
                 from drivers/net/ethernet/broadcom/bnxt/bnxt.c:10:
drivers/net/ethernet/broadcom/bnxt/bnxt.c: In function 'bnxt_get_max_rings':
include/linux/kernel.h:794:26: warning: 'cp' may be used uninitialized in this function [-Wmaybe-uninitialized]
include/linux/kernel.h:794:26: warning: 'tx' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/net/ethernet/broadcom/bnxt/bnxt.c:5730:11: warning: 'rx' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/net/ethernet/broadcom/bnxt/bnxt.c:5736:6: note: 'rx' was declared here

This changes the condition so that we fall back to using the PF
data if VF is not available, and always initialize the variables
to something useful.
