Johannes Berg 787d6c1f17 iwlwifi: mvm: BT Coex - remove shadowing variable
The variable 'u32 mode' exists twice, the latter shadowing
the former - remove the latter since there's no need for
two variables.

David S. Miller 45ce829dd0 Merge tag 'master-2014-09-04' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless
John W. Linville says:

====================
pull request: wireless 2014-09-05

Please pull this batch of fixes intended for the 3.17 stream...

For the mac80211 bits, Johannes says:

"Here are a few fixes for mac80211. One has been discussed for a while
and adds a terminating NUL-byte to the alpha2 sent to userspace, which
shouldn't be necessary but since many places treat it as a string we
couldn't move to just sending two bytes.

In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
fix for the recently introduced RX aggregation offload, a revert for
a broken patch (that luckily didn't really cause any harm) and a small
fix for alignment in debugfs."

For the iwlwifi bits, Emmanuel says:

"I revert a patch that disabled CTS to self in dvm because users
reported issues. The revert is CCed to stable since the offending
patch was sent to stable too. I also bump the firmware API versions
since a new firmware is coming up. On top of that, Marcel fixes a
bug I introduced while fixing a bug in our Kconfig file."

Please let me know if there are problems!

WANG Cong de185ab46c ipv6: restore the behavior of ipv6_sock_ac_drop()
It is possible that the interface is already gone after joining
the list of anycast on this interface as we don't hold a refcount
for the device, in this case we are safe to ignore the error.

What's more important, for API compatibility we should not
change this behavior for applications even if it were correct.

The example code provided with the i2c device interface documentation
won't compile since it uses the reserved word "register" to name a
variable.

The compiler fails with this error message:

 error: expected identifier or '(' before '=' token
   __u8 register = 0x20; /* Device register to access */
                 ^

Rename the variable "register" to simply "reg" in the example code.

Alexey Khoroshilov 9ef7db7f38 ufs: fix deadlocks introduced by sb mutex merge
Commit 0244756edc ("ufs: sb mutex merge + mutex_destroy") introduces
deadlocks in ufs_new_inode() and ufs_free_inode().
Most callers of that functions acqure the mutex by themselves and
ufs_{new,free}_inode() do that via lock_ufs(),
i.e we have an unavoidable double lock.

The patch proposes to resolve the issue by making sure that
ufs_{new,free}_inode() are not called with the mutex held.

Found by Linux Driver Verification project (linuxtesting.org).

Pull xfs fixes from Dave Chinner:
 "The fixes all address recently discovered data corruption issues.

  The original Direct IO issue was discovered by Chris Mason @ Facebook
  on a production workload which mixed buffered reads with direct reads
  and writes IO to the same file.  The fix for that exposed other issues
  with page invalidation (exposed by millions of fsx operations) failing
  due to dirty buffers beyond EOF.

  Finally, the collapse_range code could also cause problems due to
  racing writeback changing the extent map while it was being shifted
  around.  The commits for that problem are simple mitigation fixes that
  prevent the problem from occuring.  A more robust fix for 3.18 that
  addresses the underlying problem is currently being worked on by
  Brian.

  Summary of fixes:
   - a direct IO read/buffered read data corruption
   - the associated fallout from the DIO data corruption fix
   - collapse range bugs that are potential data corruption issues"

Thomas Gleixner 9bf2419fa7 timekeeping: Update timekeeper before updating vsyscall and pvclock
The update_walltime() code works on the shadow timekeeper to make the
seqcount protected region as short as possible. But that update to the
shadow timekeeper does not update all timekeeper fields because it's
sufficient to do that once before it becomes life. One of these fields
is tkr.base_mono. That stays stale in the shadow timekeeper unless an
operation happens which copies the real timekeeper to the shadow.

The update function is called after the update calls to vsyscall and
pvclock. While not correct, it did not cause any problems because none
of the invoked update functions used base_mono.

commit cbcf2dd3b3 (x86: kvm: Make kvm_get_time_and_clockread()
nanoseconds based) changed that in the kvm pvclock update function, so
the stale mono_base value got used and caused kvm-clock to malfunction.

Put the update where it belongs and fix the issue.

Lendacky, Thomas a3ba7c989d amd-xgbe: Enable interrupts for all management counters
As the management counters reach a threshold they will generate an
interrupt so the value can be saved and the counter reset. The
current code does not enable this interrupt on all counters. This
can result in inaccurate statistics.

Update the code to enable all the counters to generate an interrupt
when its threshold is exceeded.

Lendacky, Thomas 6026510896 amd-xgbe: Treat certain counter registers as 64 bit
Even if the management counters are configured to be 32 bit register
values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are
always 64 bit counter registers.  Since they are not being treated as
64 bit values, these statistics are being reported incorrectly (ifconfig,
ethtool, etc.).

Update the routines used to read the registers to access the "hi"
register (an offset of 4 from the "lo" register) to create a 64 bit
value for these 64 bit counters.

Daniel Hellstrom e1743a16a0 greth: moved TX ring cleaning to NAPI rx poll func
This patch does not affect the 10/100 GRETH MAC.

Before all GBit GRETH TX descriptor ring cleaning was done in
start_xmit(), when descriptor list became full it activated
TX interrupt to start the NAPI rx poll function to do TX ring
cleaning.

With this patch the TX descriptor ring is always cleaned from
the NAPI rx poll function, triggered via TX or RX interrupt.
Otherwise we could end up in TX frames being sent but not
reported to the stack being sent. On the 10/100 GRETH this
is not an issue since the SKB is copied&aligned into private
buffers so that the SKB can be freed directly on start_xmit()

But the problem seems to still exist upstream.  It seems on 32 bit kernels
page_address() can reutrn a NULL value in some circumstances, and the
pci_map_single api isn't prepared to handle that (on this system it results in a
bogus pointer deference in nommu_map_page.

The fix is pretty easy, if we convert the 3c59x driver to use the more
convieient skb_frag_dma_map api we don't need to find the virtual address of the
page at all, and page gets mapped to the hardware properly.  Verified to fix the
problem as described by the reporter.

Applies to the net tree

Change Notes:

v2) Converted PCI_DMA_TODEVICE to DMA_TO_DEVICE.  Thanks Dave!

v3) Actually Run git commit after making changes to v2 :)

Willem de Bruijn c199105d15 net-timestamp: only report sw timestamp if reporting bit is set
The timestamping API has separate bits for generating and reporting
timestamps. A software timestamp should only be reported for a packet
when the packet has the relevant generation flag (SKBTX_..) set
and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set.

The second check was accidentally removed. Reinstitute the original
behavior.

Tested:
  Without this patch, Documentation/networking/txtimestamp reports
  timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set.
  After the patch, it only reports them when the flag is set.

Guillaume Nault eed4d839b0 l2tp: fix race while getting PMTU on PPP pseudo-wire
Use dst_entry held by sk_dst_get() to retrieve tunnel's PMTU.

The dst_mtu(__sk_dst_get(tunnel->sock)) call was racy. __sk_dst_get()
could return NULL if tunnel->sock->sk_dst_cache was reset just before the
call, thus making dst_mtu() dereference a NULL pointer:

Pawel Moll 8fb2226435 bus: arm-ccn: Move event cleanup routine
The function cleaning up an initialized event
was called from the "event_del" handler, instead
of being used as the "destroy" callback. In case of
events group allocation this caused NULL pointer
dereference (as events are added and deleted
multiple times then). Fixed now.

Sabrina Dubroca a9ed4a2986 ipv6: fix rtnl locking in setsockopt for anycast and multicast
Calling setsockopt with IPV6_JOIN_ANYCAST or IPV6_LEAVE_ANYCAST
triggers the assertion in addrconf_join_solict()/addrconf_leave_solict()

ipv6_sock_ac_join(), ipv6_sock_ac_drop(), ipv6_sock_ac_close() need to
take RTNL before calling ipv6_dev_ac_inc/dec. Same thing with
ipv6_sock_mc_join(), ipv6_sock_mc_drop(), ipv6_sock_mc_close() before
calling ipv6_dev_mc_inc/dec.

This patch moves ASSERT_RTNL() up a level in the call stack.
