Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2016-04-25 This series contains updates to ixgbe and ixgbevf. Emil provides several patches, starting with the consolidation of the logic behind configuring spoof checking. Fixed an issue which was causing link issues for backplane devices because x550em_a/x devices did not have a default value for mac->ops.setup_link. Refactored the ethtool stats to bring the logic closer to how ixgbe handles stats and sets up per-queue stats for ixgbevf. Mark adds a new register to wait for previous register writes to complete before issuing a register read, which is needed when slower links are in use. Fixed the flow control setup for x550em_a, the incorrect fc_setup function was being used. Don added a workaround for empty SFP+ cage crosstalk, since on some systems the crosstalk could lead to link flap on empty SFP+ cages. Jake converts ixgbe and ixgbevf to use the BIT() macro. Alex Duyck adds support for partial GSO segmentation in the case of tunnels for ixgbe and ixgbevf. Then preps for HyperV by moving the API negotiation into mac_ops. Arnd Bergmann provides a fix for the ARM compile warnings in linux-next by converting the use of a udelay() to msleep(). ==================== Signed-off-by:

The newly added x550em_a support causes a link failure on ARM because of an overly long time passed into udelay(): ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined! There are multiple variants of the ixgbe_acquire_swfw_sync_*() function, and the other ones all use msleep(), so we can safely assume that all callers are allowed to sleep, which makes msleep() a better replacement than mdelay().

This patch moves API negotiation into mac_ops.

This patch adds support for partial GSO segmentation in the case of tunnels. Specifically with this change the driver an perform segmentation as long as the frame either has IPv6 inner headers, or we are allowed to mangle the IP IDs on the inner header. This is needed because we will not be modifying any fields from the start of the start of the outer transport header to the start of the inner transport header as we are treating them like they are just a block of IP options.

Several areas of ixgbe were written before widespread usage of the BIT(n) macro. With the impending release of GCC 6 and its associated new warnings, some usages such as (1 << 31) have been noted within the ixgbe driver source. Fix these wholesale and prevent future issues by simply using BIT macro instead of hand coded bit shifts. Also fix a few shifts that are shifting values into place by using the 'u' prefix to indicate unsigned. It doesn't strictly matter in these cases because we're not shifting by too large a value, but these are all unsigned values and should be indicated as such. Signed-off-by:

This brings the logic closer to how we handle the stats in ixgbe and it sets us up for introducing per-queue stats. Use IXGBEVF_STAT and IXGBEVF_NETDEV_STAT for accessing the driver and netdev stats respectively. This way we don't have to calculate the stats based on register values which could lead to the counters not being initialized properly when the interface is down. IXGBEVF_QUEUE_STATS_LEN is set to include the number of queues. Also some defines were renamed to use the IXGBEVF prefix. Signed-off-by:

This patch sets mac->ops.setup_link to ixgbe_setup_mac_link_X540 for X550EM_a/x which is also default for X550. This will result in mac->ops.setup_link calling the link setup function for the respective PHY type in case we do not need a special function to deal with it. Reported-by:

Previously the PF driver would only set VLAN spoof checking if the VF had created VLANs. This was done by setting and checking a counter (vlan_count) whenever a VLAN was created by the VF. However it is possible for the vlan_count to be !=0 while there are no VLANs assigned to the VF due to the count incrementing every time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing always being set for those VFs. This patch cleans up the logic by unconditionally setting VLAN based on how the VF is configured (via ip link set ethX vf Y spoofchk on/off). This change also resolves an issue where the VLAN spoofing can remain set even after being disabled by the user due to the driver enabling VLAN spoof checking every time a VLAN is added to the VF, but would only allow changes in the setting if vlan_count != 0. Also default_vf_vlan_id and vlans_enabled were removed from the vf_data_storage structure since they are not being used in the driver. Signed-off-by:

Change ixgbe_set_mac_anti_spoofing() to set MAC spoofing per VF similar to the VLAN and Ethertype functions - this allows us to call the helper functions in ixgbe_ndo_set_vf_spoofchk() for all spoof check types and only disable MAC spoof checking when creating MACVLAN.

Linux TCP stack painfully segments all TSO/GSO packets before retransmits. This was fine back in the days when TSO/GSO were emerging, with their bugs, but we believe the dark age is over. Keeping big packets in write queues, but also in stack traversal has a lot of benefits. - Less memory overhead, because write queues have less skbs - Less cpu overhead at ACK processing. - Better SACK processing, as lot of studies mentioned how awful linux was at this ;) - Less cpu overhead to send the rtx packets (IP stack traversal, netfilter traversal, drivers...) - Better latencies in presence of losses. - Smaller spikes in fq like packet schedulers, as retransmits are not constrained by TCP Small Queues. 1 % packet losses are common today, and at 100Gbit speeds, this translates to ~80,000 losses per second. Losses are often correlated, and we see many retransmit events leading to 1-MSS train of packets, at the time hosts are already under stress. Signed-off-by:

They are: 1) Ensure we don't go over the ruleset blob boundaries in mark_source_chains(). 2) Validate that target jumps land on an existing xt_entry. This extra sanitization comes with a performance penalty when loading the ruleset. 3) Introduce xt_check_entry_offsets() and use it from {arp,ip,ip6}tables. 4) Get rid of the smallish check_entry() functions in {arp,ip,ip6}tables. 5) Make sure the minimal possible target size in x_tables. 6) Similar to #3, add xt_compat_check_entry_offsets() for compat code. 7) Check that standard target size is valid. 8) More sanitization to ensure that the target_offset field is correct. 9) Add xt_check_entry_match() to validate that matches are well-formed. 10-12) Three patch to reduce the number of parameters in translate_compat_table() for {arp,ip,ip6}tables by using a container structure. 13) No need to return value from xt_compat_match_from_user(), so make it void. 14) Consolidate translate_table() so it can be used by compat code too. 15) Remove obsolete check for compat code, so we keep consistent with what was already removed in the native layout code (back in 2007). 16) Get rid of target jump validation from mark_source_chains(), obsoleted by #2. 17) Introduce xt_copy_counters_from_user() to consolidate counter copying, and use it from {arp,ip,ip6}tables. 18,22) Get rid of unnecessary explicit inlining in ctnetlink for dump functions. 19) Move nf_connlabel_match() to xt_connlabel. 20) Skip event notification if connlabel did not change. 21) Update of nf_connlabels_get() to make the upcoming nft connlabel support easier. 23) Remove spinlock to read protocol state field in conntrack. ==================== Signed-off-by:

Nicolas Dichtel says: ==================== netlink: align attributes when needed (patchset #1) This is the continuation of the work done to align netlink attributes when these attributes contain some 64-bit fields. David, if the third patch is too big (or maybe the series), I can split it. Just tell me what you prefer. ==================== Signed-off-by:

Goal of this patch is to use the new libnl API to align netlink attribute when needed. The layout of the netlink message will be a bit different after the patch, because the padattr (TASKSTATS_TYPE_STATS) will be inside the nested attribute instead of before it. Signed-off-by:
