Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-09-04 This series contains updates to i40e, i40evf, ixgbe and ixgbevf. Catherine adds dual speed module support to i40e. Updates i40e to allow the user to change link settings when the link is down. Serey renames i40e_ndo_set_vf_spoofck() to i40e_ndo_set_vf_spookchk() to be more consistent with what is defined in netdev and removes a unnecessary variable assignment. Jesse makes a malicious driver detection warning only print if extended driver string is enabled for i40e. Fixes a panic under traffic load when resetting or if/whenever there was a Tx-timeout because we were enabling the Tx queue to early. Anjali fixes an issue when PF reset fails, where we were trying to restart the admin queue which has not been setup at that point. This resolves an occasional kernel panic when PF reset fails for some reason. Ethan Zhao replaces the use of a local i40e_vfs_are_assigned() with the global kernel pci_vfs_assigned() for i40e. Alex cleans up the FDB handling for ixgbe. This change makes it so that the behavior for FDB handling is consistent between both the SR-IOV and non-SR-IOV cases. The main change is that we perform bounds checking on the number of SR-IOV addresses regardless of if SR-IOV is enabled or not as we can only support a certain number of addresses in the hardware. Emil extends the pending Tx work check to the VF interfaces, where the driver initiates a reset of the interface on link loss with pending Tx work in order to clear the rings. Introduces a delay for 82599 VFs of at least 500 usecs to make sure the VFLINKS value is correct, since this bit tends to flap when a DA or SFP+ cable is disconnected. Jacob adds code comments in ixgbe to make it more obvious that we are resetting features based on the fact that we do not have MSI-X enabled, and cannot use the previous settings. Also resolves a kernel NULL pointer dereference by limiting the combined total of MACVLAN and SR-IOV VFs, since the hardware has a limited number of pools available (64). Previously, no checks were in place to limit the number of accelerated MACVLAN devices based on the number of pools, which would be ok since there was already a limit for these well below the number of available pools. However, SR-IOV uses the very same pools, therefore we need to ensure that the total number of pools does not exceed the number of pools available in the hardware. v2: - clean up code comment in patch 5 by replacing "an" with "auto negotiation" based on feedback from Sergei Shtylyov - removed un-necessary parenthesis around function call in patch 8 based on feedback from Sergei Shtylyov ====================

Simplify the interrupt resource lookup code in cpsw_probe() by the following: * Only look at the first member of the resource. As the driver only works for DT-enabled platforms anyway, a resource of type IORESOURCE_IRQ will only contain one single entry (res->start == res->end), so there is no need for the iteration. * Add a bounds check to avoid overflows if we are passed more than ARRAY_SIZE(priv->irqs_table) resources. * Assign 'ret' with the return value of devm_request_irq() so that cpsw_probe() returns the appropriate error code. * If devm_request_irq() fails, report the error code in the log message.

Govindarajulu Varadarajan says: ==================== enic: Add support for rx_copybreak The following series implements rx_copybreak. dma_map_single()/dma_unmap_single() is more expensive than alloc_skb & memcpy for smaller packets. By doing this we can reuse the dma buff which is already mapped. This is very useful when iommu is on. The default skb copybreak value is 256. When iommu is on, we can go much higher than 256. All the drivers that supports rx_copybreak provides module parameter to change this value. Since module parameter is the least preferred way for changing driver values, this series adds ethtool support for setting rx_copybreak. v4: Validate tunable length in ethtool_get_tunable, not in driver implemented function. Loose tunable_ops array for each tunable type. Define one function and let the driver use switch case for each type. Use double underscore for data type in UAPI headers. Use const qualifier where possible. v3: Add tunable namespace to ethtool. Use new ethtool cmd ETHTOOL_S/GTUNABLE to set/get rx_copybreak from userspace. v2: Add new ethtool_cmd for DMA buffer parameters, instead of adding new members to existing ethtool_ringparam. ==================== Signed-off-by:

Marcel reported to see the following message when autoloading is being triggered when adding nlmon device: Loading kernel module for a network device with CAP_SYS_MODULE (deprecated). Use CAP_NET_ADMIN and alias netdev-nlmon instead. This false-positive happens despite with having correct capabilities set, e.g. through issuing `ip link del dev nlmon` more than once on a valid device with name nlmon, but Marcel has also seen it on creation time when no nlmon module is previously compiled-in or loaded as module and the device name equals a link type name (e.g. nlmon, vxlan, team). Stephen says: The netdev module alias is a hold over from the past. For normal devices, people used to create a alias eth0 to and point it to the type of network device used, that was back in the bad old ISA days before real discovery. Also, the tunnels create module alias for the control device and ip used to use this to autoload the tunnel device. The message is bogus and should just be removed, I also see it in a couple of other cases where tap devices are renamed for other usese. As mentioned in 8909c9ad ("net: don't allow CAP_NET_ADMIN to load non-netdev kernel modules"), we nevertheless still might want to leave the old autoloading behaviour in place as it could break old scripts, so for now, lets just remove the log message as Stephen suggests.

With eBPF getting more extended and exposure to user space is on it's way, hardening the memory range the interpreter uses to steer its command flow seems appropriate. This patch moves the to be interpreted bytecode to read-only pages. In case we execute a corrupted BPF interpreter image for some reason e.g. caused by an attacker which got past a verifier stage, it would not only provide arbitrary read/write memory access but arbitrary function calls as well. After setting up the BPF interpreter image, its contents do not change until destruction time, thus we can setup the image on immutable made pages in order to mitigate modifications to that code. The idea is derived from commit 314beb9b ("x86: bpf_jit_comp: secure bpf jit against spraying attacks"). This is possible because bpf_prog is not part of sk_filter anymore. After setup bpf_prog cannot be altered during its life-time. This prevents any modifications to the entire bpf_prog structure (incl. function/JIT image pointer). Every eBPF program (including classic BPF that are migrated) have to call bpf_prog_select_runtime() to select either interpreter or a JIT image as a last setup step, and they all are being freed via bpf_prog_free(), including non-JIT. Therefore, we can easily integrate this into the eBPF life-time, plus since we directly allocate a bpf_prog, we have no performance penalty. Tested with seccomp and test_bpf testsuite in JIT/non-JIT mode and manual inspection of kernel_page_tables. Brad Spengler proposed the same idea via Twitter during development of this patch. Joint work with Hannes Frederic Sowa. Suggested-by:

When we bring the interface down, phy_stop() will schedule the PHY state machine to call our link adjustment callback. By the time we do so, we may have clock gated off the SYSTEMPORT hardware block, and this will cause bus errors to happen in bcm_sysport_adj_link(): Make sure that we only touch the UMAC_CMD register when there is an actual link. This is safe to do for two reasons: - updating the Ethernet MAC registers only make sense when a physical link is present - the PHY library state machine first set phydev->link = 0 before invoking phydev->adjust_link in the PHY_HALTED case This is a similar fix to the GENET one: c677ba8b ("net: bcmgenet: update UMAC_CMD only when link is detected").

This patch adds a new sysctl_mld_qrv knob to configure the mldv1/v2 query robustness variable. It specifies how many retransmit of unsolicited mld retransmit should happen. Admins might want to tune this on lossy links. Also reset mld state on interface down/up, so we pick up new sysctl settings during interface up event. IPv6 certification requests this knob to be available. I didn't make this knob netns specific, as it is mostly a setting in a physical environment and should be per host.

Hardware has a limited number of pools available (64). Previously, no checks were in place to limit the number of accelerated macvlan devices based on the number of pools. Normally this would be ok, because there was already a limit for these well below the number of available pools. However, SR-IOV uses the very same pools. Therefor, we need to ensure that the total number of pools (number of VFs plus the number of non-VF pools in use for accelerated macvlans) does not exceed the number of pools available in hardware.

The driver is un-necessarily printing a warning that is only marginally useful to the user. Make the warning only print if extended driver string printing is enabled, other messages related to a reset event will still continue to print.

Since we don't seem to be getting an LSE telling us link is going down during set_phy_config (but we do get an LSE telling us we are coming back up), fake one for the OS and tell them link is going down. Also do an atomic restart no matter what because there are times the user may want to end with link up even if they started with link down (like if they accidentally set it to a speed that can't link and are trying to fix it).

Now that fw has implemented dual speed module support, we can add ours. Also, add the phy type for 1G LR/SR and set its media type to fiber. Lastly, instead of a WARN_ON if the phy type is not recognized just print a warning. Change-ID: I2e5227d4a8c2907b0ed423038e5dbce774e466b0 Signed-off-by:

It would appear the mlx4_en driver was still making a call to dev_kfree_skb_any() where dev_consume_skb_any() would be more appropriate. This should make dropped packet profiling/tracking easier/better over a NIC driven by mlx4_en. Signed-off-by:
