Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next

Conflicts:
net/netfilter/nf_log.c

The conflict in nf_log.c is that in 'net' we added CONFIG_PROC_FS
protection around foo_proc_entry() calls to fix a build failure,
whereas in Pablo's tree a guard if() test around a call is
remove_proc_entry() was removed.  Trivially resolved.

Pablo Neira Ayuso says:

====================
The following patchset contains the first batch of
Netfilter/IPVS updates for your net-next tree, they are:

* Three patches with improvements and code refactorization
  for nfnetlink_queue, from Florian Westphal.

* FTP helper now parses replies without brackets, as RFC1123
  recommends, from Jeff Mahoney.

* Rise a warning to tell everyone about ULOG deprecation,
  NFLOG has been already in the kernel tree for long time
  and supersedes the old logging over netlink stub, from
  myself.

* Don't panic if we fail to load netfilter core framework,
  just bail out instead, from myself.

* Add cond_resched_rcu, used by IPVS to allow rescheduling
  while walking over big hashtables, from Simon Horman.

* Change type of IPVS sysctl_sync_qlen_max sysctl to avoid
  possible overflow, from Zhang Yanfei.

* Use strlcpy instead of strncpy to skip zeroing of already
  initialized area to write the extension names in ebtables,
  from Chen Gang.

* Use already existing per-cpu notrack object from xt_CT,
  from Eric Dumazet.

* Save explicit socket lookup in xt_socket now that we have
  early demux, also from Eric Dumazet.

This patch adds the intermediate solution of reading the MAC address
from the hardware registers, in case it has been set by the
bootloader. So the order is now:

 1) MAC address from the Device Tree
 2) MAC address from the hardware registers
 3) Random MAC address

This requires moving the MAC address initialization a little bit later
in the ->probe() code, because it now requires the hardware registers
to be remapped.

net: mv643xx_eth: add missing semicolon

76723bca28 "net: mv643xx_eth: add DT parsing support" added a
dummy mv643xx_eth_shared_of_probe() fallback function with a
typo.

This adds the missing semicolon so we can build without CONFIG_OF
again, and changes both dummy functions to the more conventional
"static inline" syntax, which can avoid potential problems with

bnx2x: Fix bridged GSO for 57710/57711 chips

It was recently found out that GSO on 57710/57711 was broken, due to packets
being sent without a valid IP checksum.

Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this
issue, but failed to set the correct IP checksum when receiving GSO packets
via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed
to calculate IP checksum were erroneously set in the incorrect
buffer descriptor.

This patch re-enables GSO in said scenario for 57710/57711 chips.

net/mlx4_core: Return -EPROBE_DEFER when a VF is probed before PF is sufficiently initialized

In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).

Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

Input: synaptics - fix sync lost after resume on some laptops

In summary, the symptom is intermittent key events lost after resume
on some machines with synaptics touchpad (seems this is synaptics _only_),
and key events loss is due to serio port reconnect after psmouse sync lost.
Removing psmouse and inserting it back during the suspend/resume process
is able to work around the issue, so the difference between psmouse_connect()
and psmouse_reconnect() is the key to the root cause of this problem.

After comparing the two different paths, synaptics driver has its own
implementation of synaptics_reconnect(), and the missing psmouse_probe()
seems significant, the patch below added psmouse_probe() to the reconnect
process, and has been verified many times that the issue could not be reliably
reproduced.

There are two PS/2 commands in psmouse_probe():

  1. PSMOUSE_CMD_GETID
  2. PSMOUSE_CMD_RESET_DIS

Only the PSMOUSE_CMD_GETID seems to be significant. The
PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
several times.  So we have only implemented this patch to issue
the PSMOUSE_CMD_GETID so far.

fuse: fix alignment in short read optimization for async_dio

The bug was introduced with async_dio feature: trying to optimize short reads,
we cut number-of-bytes-to-read to i_size boundary. Hence the following example:

truncate --size=300 /mnt/file
dd if=/mnt/file of=/dev/null iflag=direct

led to FUSE_READ request of 300 bytes size. This turned out to be problem
for userspace fuse implementations who rely on assumption that kernel fuse
does not change alignment of request from client FS.

The patch turns off the optimization if async_dio is disabled. And, if it's
enabled, the patch fixes adjustment of number-of-bytes-to-read to preserve
alignment.

Note, that we cannot throw out short read optimization entirely because
otherwise a direct read of a huge size issued on a tiny file would generate
a huge amount of fuse requests and most of them would be ACKed by userspace
with zero bytes read.

KVM: Fix race in apic->pending_events processing

with the KVM_ARM_VCPU_INIT ioctl before being used with further
requests. KVM_RUN checks whether this initialization has been
done, but other ioctls do not.
Namely KVM_GET_REG_LIST will dereference an array with index -1
