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