====================
pull request (net-next): ipsec-next 2015-05-28

1) Remove xfrm_queue_purge as this is the same as skb_queue_purge.

2) Optimize policy and state walk.

3) Use a sane return code if afinfo registration fails.

4) Only check fori a acquire state if the state is not valid.

5) Remove a unnecessary NULL check before xfrm_pol_hold
   as it checks the input for NULL.

6) Return directly if the xfrm hold queue is empty, avoid
   to take a lock as it is nothing to do in this case.

7) Optimize the inexact policy search and allow for matching
   of policies with priority ~0U.

All from Li RongQing.

Please pull or let me know if there are problems.

      net: qlcnic: clean up sysfs error codes · d7a32b6e
      Vladimir Zapolskiy authored 
      Replace confusing QL_STATUS_INVALID_PARAM == -1 == -EPERM with -EINVAL
and QLC_STATUS_UNSUPPORTED_CMD == -2 == -ENOENT with -EOPNOTSUPP, the
latter error code is arguable, but it is already used in the driver,
so let it be here as well.

Also remove always false (!buf) check on read(), the driver should
not care if userspace gets its EFAULT or not.

      tcp: fix/cleanup inet_ehash_locks_alloc() · 095dc8e0
      Eric Dumazet authored 
      If tcp ehash table is constrained to a very small number of buckets
(eg boot parameter thash_entries=128), then we can crash if spinlock
array has more entries.

While we are at it, un-inline inet_ehash_locks_alloc() and make
following changes :

- Budget 2 cache lines per cpu worth of 'spinlocks'
- Try to kmalloc() the array to avoid extra TLB pressure.
  (Most servers at Google allocate 8192 bytes for this hash table)
- Get rid of various #ifdef

      tipc: fix bug in link protocol message create function · f3903bcc
      Jon Paul Maloy authored 
      In commit dd3f9e70
("tipc: add packet sequence number at instant of transmission") we
made a change with the consequence that packets in the link backlog
queue don't contain valid sequence numbers.

However, when we create a link protocol message, we still use the
sequence number of the first packet in the backlog, if there is any,
as "next_sent" indicator in the message. This may entail unnecessary
retransissions or stale packet transmission when there is very low
traffic on the link.

This commit fixes this issue by only using the current value of
tipc_link::snd_nxt as indicator.

      bridge: skip fdb add if the port shouldn't learn · eb8d7baa
      Wilson Kok authored 
      Check in fdb_add_entry() if the source port should learn, similar
check is used in br_fdb_update.
Note that new fdb entries which are added manually or
as local ones are still permitted.
This patch has been tested by running traffic via a bridge port and
switching the port's state, also by manually adding/removing entries
from the bridge's fdb.
