Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) IPv6 gre tunnels end up with different default features enabled depending upon whether netlink or ioctls are used to bring them up. Fix from Alexey Kodanev. 2) Fix read past end of user control message in RDS< from Avinash Repaka. 3) Missing RCU barrier in mini qdisc code, from Cong Wang. 4) Missing policy put when reusing per-cpu route entries, from Florian Westphal. 5) Handle nested PCI errors properly in bnx2x driver, from Guilherme G. Piccoli. 6) Run nested transport mode IPSEC packets via tasklet, from Herbert Xu. 7) Fix handling poll() for stream sockets in tipc, from Parthasarathy Bhuvaragan. 8) Fix two stack-out-of-bounds issues in IPSEC, from Steffen Klassert. 9) Another zerocopy ubuf handling fix, from Willem de Bruijn. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (33 commits) strparser: Call sock_owned_by_user_nocheck sock: Add sock_owned_by_user_nocheck skbuff: in skb_copy_ubufs unclone before releasing zerocopy tipc: fix hanging poll() for stream sockets sctp: Replace use of sockets_allocated with specified macro. bnx2x: Improve reliability in case of nested PCI errors tg3: Enable PHY reset in MTU change path for 5720 tg3: Add workaround to restrict 5762 MRRS to 2048 tg3: Update copyright net: fec: unmap the xmit buffer that are not transferred by DMA tipc: fix tipc_mon_delete() oops in tipc_enable_bearer() error path tipc: error path leak fixes in tipc_enable_bearer() RDS: Check cmsg_len before dereferencing CMSG_DATA tcp: Avoid preprocessor directives in tracepoint macro args tipc: fix memory leak of group member when peer node is lost net: sched: fix possible null pointer deref in tcf_block_put tipc: base group replicast ack counter on number of actual receivers net_sched: fix a missing rcu barrier in mini_qdisc_pair_swap() net: phy: micrel: ksz9031: reconfigure autoneg after phy autoneg workaround ip6_gre: fix device features for ioctl setup ...
