For consistency with the other similar methods in the kernel pass a struct sock into the dst_ops .local_out method.

2015-10-08ipv4: Fix ip_queue_xmit to pass sk into ip_local_out_skEric W. Biederman1-1/+1
After a packet has been encapsulated by a tunnel we should use the tunnel sockets local multicast loopback flag to control if the encapsulated packet should be locally loopback back. Pass sk into ip_local_out_sk so that in the rare case we are dealing with a tunneled packet whose tunnel destination address is a multicast address the kernel properly decides to loopback this packet. In practice I don't think this matters as ip_queue_xmit is used by tcp, l2tp and sctp none of which I am aware of uses ip level multicasting as they are all point to point communications protocols. Let's fix this before someone uses ip_queue_xmit for a tunnel protocol that does use multicast. Fixes: aad88724c9d5 ("ipv4: add a sock pointer to dst->output() path.")

2015-10-08ipv4: Fix ip_local_out_sk by passing the sk into __ip_local_out_skEric W. Biederman1-1/+1
In the rare case where sk != skb->sk ip_local_out_sk arranges to call dst->output differently if the skb is queued or not. This is a bug. Fix this bug by passing the sk parameter of ip_local_out_sk through from ip_local_out_sk to __ip_local_out_sk (skipping __ip_local_out).

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-07 This series contains updates to i40e and i40evf only. Paul updates i40e to simply increase the amount of time we wait for a reset to complete since we have seen in some rare occasions the reset can take longer to complete. Shannon updates the driver to turn on Wake-on-LAN by default if it is enabled in the hardware config to begin with, rather than always disable it and wait for the user to expressly turn it on. Added new device id's and support for future devices. Fixed a possible type compare problem between a size and possible negative number. Also fixed a shift value that was wrong, which ended up with a bad bitmask. Did general house cleaning of the driver to cleanup several low lying fruit in the driver. Fixed an issue where new unicast address's would be added to the VSI list and then immediately removed and would never actually make it down to the hardware. Resolved the issue by removing the separation from unicast and multicast in the search for filters to be deleted. Mitch fixes an issue where the hardware would continue to access the memory formerly used by the rings for a VF which have been removed, causing memory corruption or DMAR errors. To relieve this condition, explicitly stop all rings associated with each VF before releasing its resources. Also fixed a panic if the driver is unable to enable MSI-X or its unable to acquire enough vectors, so propagate interrupt allocation failure information to the calling function. Cleaned up opcode that is not required. Carolyn extends the size of the test available for the interrupt names so that all the descriptive data available for the Flow Director interrupts is not truncated. Catherine fixes an issue where there was a possibility of speed getting set to 0 if advertised is set to 0 (which is the case when autoneg is disabled). Jesse fixes the checksum on big endian machines, so added code to swap it correctly. Also fixed a bug in the return from get_link_status() where only true or false was being returned, but false could mean multiple things. So allow the caller to get all the return values in the call chain bubbled back to the source so that the reason for the failure does not get lost. Anjali adds statistics to keep track of how many times we ask the stack to linearize the SKB because the hardware cannot handle SKBs with more than 8 frags per segment/single packet. ==================== Signed-off-by: David S.

2015-10-08mmc: host: omap_hsmmc: Fix MMC for omap3 legacy bootingTony Lindgren1-3/+3
Starting with commit 7d607f917008 ("mmc: host: omap_hsmmc: use devm_regulator_get_optional() for vmmc") MMC on omap3 stopped working for legacy booting. This is because legacy booting sets up some of the resource in the platform init code, and for optional regulators always seem to return -EPROBE_DEFER for the legacy booting. Let's fix the issue by checking for device tree based booting for now. Then when omap3 boots in device tree only mode, this patch can be just reverted.

2015-10-08i40e/i40evf: fix unicast mac address addShannon Nelson2-48/+38
When using something like "ip maddr add ..." to add another unicast mac address to the netdev, the mac address comes into the set_rx_mode handler in the multicast list whether it is a unicast or multicast address. This was confusing the code when it was trying to search for addresses that needed to be deleted from the VSI, because it was looking for the VSI unicast address in the netdev unicast list. The result was that a new unicast address would get added to the VSI list and then immediately removed, and would never actually make it down into the hardware. This patch removes the separation from unicast and multicast in the search for filters to be deleted. It also simplifies the logic a little with a jump to the bottom of the loop when an address is found. Now it doesn't matter which netdev list the address is hiding in, we'll check them all.

2015-10-08i40e: fix bug in return from get_link_status and avoid spurious link messagesJesse Brandeburg4-11/+29
Previously, the driver could call this function and have only true/false returned, but false could mean multiple things like failure to read or link was down. This change allows the caller to get all return values in the call chain bubbled back to the source, which keeps information about failures from being lost. Also, in some unlikely scenarios, the firmware can become slow to respond to admin queue (AQ) queries for link state. Should the AQ time out, the driver can detect the state and avoid a link change when there may have been none.

2015-10-07i40e: stop VF ringsMitch Williams1-0/+5
Explicitly stop the rings belonging to each VF when disabling SR-IOV. Even though the VFs were gone, and the associated VSIs were removed, the rings were not stopped, and in some circumstances the hardware would continue to access the memory formerly used by the rings, causing memory corruption or DMAR errors, both of which would lead to general malaise of the kernel. To relieve this condition, explicitly stop all the rings associated with each VF before releasing its resources.

2015-10-07i40e: enable WoL operation if config bit show WoL capableShannon Nelson1-2/+7
The driver was disabling Wake-on-LAN by default and waiting for the user to expressly turn it on. This patch has the driver turning on WoL from the start if enabled in the hardware config, which matches the behavior of our other drivers.

2015-10-07i40e: Increase the amount of time we wait for reset to be donePaul M Stillwell Jr1-1/+1
In some rare cases the reset can take longer to complete so increase the amount of time we wait.

2015-10-07swiotlb: Enable it under x86 PAEChristian Melki1-0/+1
Most distributions end up enabling SWIOTLB already with 32-bit kernels due to the combination of CONFIG_HYPERVISOR_GUEST|CONFIG_XEN=y as those end up requiring the SWIOTLB. However for those that are not interested in virtualization and run in 32-bit they will discover that: "32-bit PAE 4.2.0 kernel (no IOMMU code) would hang when writing to my USB disk. The kernel spews million(-ish messages per sec) to syslog, effectively "hanging" userspace with my kernel. Oct 2 14:33:06 voodoochild kernel: [ 223.287447] nommu_map_sg: overflow 25dcac000+1024 of device mask ffffffff Oct 2 14:33:06 voodoochild kernel: [ 223.287448] nommu_map_sg: overflow 25dcac000+1024 of device mask ffffffff Oct 2 14:33:06 voodoochild kernel: [ 223.287449] nommu_map_sg: overflow 25dcac000+1024 of device mask ffffffff ... etc ..." Enabling it makes the problem go away. N.B. With a6dfa128ce5c414ab46b1d690f7a1b8decb8526d "config: Enable NEED_DMA_MAP_STATE by default when SWIOTLB is selected" we also have the important part of the SG macros enabled to make this work properly - in case anybody wants to backport this patch.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.3 Quite a few fixes here but they're all very small and driver specific, none of them really stand out if you aren't using the relevant hardware but they're all useful if you do happen to have an affected device.
