====================
pull-request: bpf 2018-01-13

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Follow-up fix to the recent BPF out-of-bounds speculation
   fix that prevents max_entries overflows and an undefined
   behavior on 32 bit archs on index_mask calculation, from
   Daniel.

2) Reject unsupported BPF_ARSH opcode in 32 bit ALU mode that
   was otherwise throwing an unknown opcode warning in the
   interpreter, from Daniel.

3) Typo fix in one of the user facing verbose() messages that
   was added during the BPF out-of-bounds speculation fix,
   from Colin.

Mellanox, mlx5 fixes 2018-01-11

The following series includes fixes to mlx5 core and netdev driver.
To highlight we have two critical fixes in this series:
1st patch from Eran to address a fix for Host2BMC Breakage.

2nd patch from Saeed to address the RDMA IRQ vector affinity settings query
issue, the patch provides the correct mlx5_core implementation for RDMA to
correctly  query vector affinity.
I sent this patch privately to Sagi a week a go, so he could to test it
but I didn't hear from him.

All other patches are trivial misc fixes.
Please pull and let me know if there's any problem.

for -stable v4.14-y and later:
("net/mlx5: Fix get vector affinity helper function")
("{net,ib}/mlx5: Don't disable local loopback multicast traffic when needed")

Note: Merging this series with net-next will produce the following conflict:

====================
pull request (net): ipsec 2018-01-11

1) Don't allow to change the encap type on state updates.
   The encap type is set on state initialization and
   should not change anymore. From Herbert Xu.

2) Skip dead policies when rehashing to fix a
   slab-out-of-bounds bug in xfrm_hash_rebuild.
   From Florian Westphal.

3) Two buffer overread fixes in pfkey.
   From Eric Biggers.

4) Fix rcu usage in xfrm_get_type_offload,
   request_module can sleep, so can't be used
   under rcu_read_lock. From Sabrina Dubroca.

5) Fix an uninitialized lock in xfrm_trans_queue.
   Use __skb_queue_tail instead of skb_queue_tail
   in xfrm_trans_queue as we don't need the lock.
   From Herbert Xu.

6) Currently it is possible to create an xfrm state with an
   unknown encap type in ESP IPv4. Fix this by returning an
   error on unknown encap types. Also from Herbert Xu.

7) Fix sleeping inside a spinlock in xfrm_policy_cache_flush.
   From Florian Westphal.

8) Fix ESP GRO when the headers not fully in the linear part
   of the skb. We need to pull before we can access them.

9) Fix a skb leak on error in key_notify_policy.

10) Fix a race in the xdst pcpu cache, we need to
    run the resolver routines with bottom halfes
    off like the old flowcache did.

      net/mlx5e: Remove timestamp set from netdevice open flow · 237f258c
      Feras Daoud authored 
      To avoid configuration override, timestamp set call will
be moved from the netdevice open flow to the init flow.
By this, a close-open procedure will not override the timestamp
configuration.
In addition, the change will rename mlx5e_timestamp_set function
to be mlx5e_timestamp_init.

      net/mlx5e: Don't override netdev features field unless in error flow · 75b81ce7
      Gal Pressman authored 
      Set features function sets dev->features in order to keep track of which
features were successfully changed and which weren't (in case the user
asks for more than one change in a single command).

This breaks the logic in __netdev_update_features which assumes that
dev->features is not changed on success and checks for diffs between
features and dev->features (diffs that might not exist at this point
because of the driver override).

The solution is to keep track of successful/failed feature changes and
assign them to dev->features in case of failure only.

      net/mlx5e: Keep updating ethtool statistics when the interface is down · e556f6dd
      Gal Pressman authored 
      ethtool statistics should be updated even when the interface is down
since it shows more than just netdev counters, which might change while
the logical link is down.
One useful use case, for example, is when running RoCE traffic over the
interface (while the logical link is down, but physical link is up) and
examining rx_prioX_bytes.
