      ipv4: Fix ip_queue_xmit to pass sk into ip_local_out_sk · 850dcc4d
      Eric W. Biederman authored 
      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.

      ipv4: Fix ip_local_out_sk by passing the sk into __ip_local_out_sk · fd2874b3
      Eric W. Biederman authored 
      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).

Fixes: 7026b1dd ("netfilter: Pass socket pointer down through okfn().")

====================
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.

      Merge tag 'regmap-offload-update-bits' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

regmap: Allow buses to provide a custom update_bits() operation

Some buses provide a native _update_bits() operation which for uncached
registers is faster than doing a read/modify/write cycle as it is a
single bus transaction.  Add support for implementing this to regmap.
