Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix memory leaks and other issues in mwifiex driver, from Amitkumar Karwar. 2) skb_segment() can choke on packets using frag lists, fix from Herbert Xu with help from Eric Dumazet and others. 3) IPv4 output cached route instantiation properly handles races involving two threads trying to install the same route, but we forgot to propagate this logic to input routes as well. Fix from Alexei Starovoitov. 4) Put protections in place to make sure that recvmsg() paths never accidently copy uninitialized memory back into userspace and also make sure that we never try to use more that sockaddr_storage for building the on-kernel-stack copy of a sockaddr. Fixes from Hannes Frederic Sowa. 5) R8152 driver transmit flow bug fixes from Hayes Wang. 6) Fix some minor fallouts from genetlink changes, from Johannes Berg and Michael Opdenacker. 7) AF_PACKET sendmsg path can race with netdevice unregister notifier, fix by using RCU to make sure the network device doesn't go away from under us. Fix from Daniel Borkmann. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (43 commits) gso: handle new frag_list of frags GRO packets genetlink: fix genl_set_err() group ID genetlink: fix genlmsg_multicast() bug packet: fix use after free race in send path when dev is released xen-netback: stop the VIF thread before unbinding IRQs wimax: remove dead code net/phy: Add the autocross feature for forced links on VSC82x4 net/phy: Add VSC8662 support net/phy: Add VSC8574 support net/phy: Add VSC8234 support net: add BUG_ON if kernel advertises msg_namelen > sizeof(struct sockaddr_storage) net: rework recvmsg handler msg_name and msg_namelen logic bridge: flush br's address entry in fdb when remove the net: core: Always propagate flag changes to interfaces ipv4: fix race in concurrent ip_route_input_slow() r8152: fix incorrect type in assignment r8152: support stopping/waking tx queue r8152: modify the tx flow r8152: fix tx/rx memory overflow netfilter: ebt_ip6: fix source and destination matching ...
