Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix refcount leak in act_ipt during replace, from Davide Caratti. 2) Set task state properly in tun during blocking reads, from Timur Celik. 3) Leaked reference in DSA, from Wen Yang. 4) NULL deref in act_tunnel_key, from Vlad Buslov. 5) cipso_v4_erro can reference the skb IPCB in inappropriate contexts thus referencing garbage, from Nazarov Sergey. 6) Don't accept RTA_VIA and RTA_GATEWAY in contexts where those attributes make no sense. 7) Fix hung sendto in tipc, from Tung Nguyen. 8) Out-of-bounds access in netlabel, from Paul Moore. 9) Grant reference leak in xen-netback, from Igor Druzhinin. 10) Fix tx stalls with lan743x, from Bryan Whitehead. 11) Fix interrupt storm with mv88e6xxx, from Hein Kallweit. 12) Memory leak in sit on device registry failure, from Mao Wenan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (44 commits) net: sit: fix memory leak in sit_init_net() net: dsa: mv88e6xxx: Fix statistics on mv88e6161 geneve: correctly handle ipv6.disable module parameter net: dsa: mv88e6xxx: prevent interrupt storm caused by mv88e6390x_port_set_cmode bpf: fix sanitation rewrite in case of non-pointers ipv4: Add ICMPv6 support when parse route ipproto MIPS: eBPF: Fix icache flush end address lan743x: Fix TX Stall Issue net: phy: phylink: fix uninitialized variable in phylink_get_mac_state net: aquantia: regression on cpus with high cores: set mode with 8 queues selftests: fixes for UDP GRO bpf: drop refcount if bpf_map_new_fd() fails in map_create() net: dsa: mv88e6xxx: power serdes on/off for 10G interfaces on 6390X net: dsa: mv88e6xxx: Fix u64 statistics xen-netback: don't populate the hash cache on XenBus disconnect xen-netback: fix occasional leak of grant ref mappings under memory pressure sctp: chunk.c: correct format string for size_t in printk net: netem: fix skb length BUG_ON in __skb_to_sgvec netlabel: fix out-of-bounds memory accesses ipv4: Pass original device to ip_rcv_finish_core ...
