Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes and more updates from David Miller:
1) Tunneling fixes from Tom Herbert and Alexander Duyck.
2) AF_UNIX updates some struct sock bit fields with the socket lock,
whereas setsockopt() sets overlapping ones with locking. Seperate
out the synchronized vs. the AF_UNIX unsynchronized ones to avoid
corruption. From Andrey Ryabinin.
3) Mount BPF filesystem with mount_nodev rather than mount_ns, from
Eric Biederman.
4) A couple kmemdup conversions, from Muhammad Falak R Wani.
5) BPF verifier fixes from Alexei Starovoitov.
6) Don't let tunneled UDP packets get stuck in socket queues, if
something goes wrong during the encapsulation just drop the packet
rather than signalling an error up the call stack. From Hannes
Frederic Sowa.
7) SKB ref after free in batman-adv, from Florian Westphal.
8) TCP iSCSI, ocfs2, rds, and tipc have to disable BH in it's TCP
callbacks since the TCP stack runs pre-emptibly now. From Eric
Dumazet.
9) Fix crash in fixed_phy_add, from Rabin Vincent.
10) Fix length checks in xen-netback, from Paul Durrant.
11) Fix mixup in KEY vs KEYID macsec attributes, from Sabrina Dubroca.
12) RDS connection spamming bug fixes from Sowmini Varadhan
