Pull networking fixes from David Miller: "A lot of Thanksgiving turkey leftovers accumulated, here goes: 1) Fix bluetooth l2cap_chan object leak, from Johan Hedberg. 2) IDs for some new iwlwifi chips, from Oren Givon. 3) Fix rtlwifi lockups on boot, from Larry Finger. 4) Fix memory leak in fm10k, from Stephen Hemminger. 5) We have a route leak in the ipv6 tunnel infrastructure, fix from Paolo Abeni. 6) Fix buffer pointer handling in arm64 bpf JIT,f rom Zi Shen Lim. 7) Wrong lockdep annotations in tcp md5 support, fix from Eric Dumazet. 8) Work around some middle boxes which prevent proper handling of TCP Fast Open, from Yuchung Cheng. 9) TCP repair can do huge kmalloc() requests, build paged SKBs instead. From Eric Dumazet. 10) Fix msg_controllen overflow in scm_detach_fds, from Daniel Borkmann. 11) Fix device leaks on ipmr table destruction in ipv4 and ipv6, from Nikolay Aleksandrov. 12) Fix use after free in epoll with AF_UNIX sockets, from Rainer Weikusat. 13) Fix double free in VRF code, from Nikolay Aleksandrov. 14) Fix skb leaks on socket receive queue in tipc, from Ying Xue. 15) Fix ifup/ifdown crach in xgene driver, from Iyappan Subramanian. 16) Fix clearing of persistent array maps in bpf, from Daniel Borkmann. 17) In TCP, for the cross-SYN case, we don't initialize tp->copied_seq early enough. From Eric Dumazet. 18) Fix out of bounds accesses in bpf array implementation when updating elements, from Daniel Borkmann. 19) Fill gaps in RCU protection of np->opt in ipv6 stack, from Eric Dumazet. 20) When dumping proxy neigh entries, we have to accomodate NULL device pointers properly, from Konstantin Khlebnikov. 21) SCTP doesn't release all ipv6 socket resources properly, fix from Eric Dumazet. 22) Prevent underflows of sch->q.qlen for multiqueue packet schedulers, also from Eric Dumazet. 23) Fix MAC and unicast list handling in bnxt_en driver, from Jeffrey Huang and Michael Chan. 24) Don't actively scan radar channels, from Antonio Quartulli" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (110 commits) net: phy: reset only targeted phy bnxt_en: Setup uc_list mac filters after resetting the chip. bnxt_en: enforce proper storing of MAC address bnxt_en: Fixed incorrect implementation of ndo_set_mac_address net: lpc_eth: remove irq > NR_IRQS check from probe() net_sched: fix qdisc_tree_decrease_qlen() races openvswitch: fix hangup on vxlan/gre/geneve device deletion ipv4: igmp: Allow removing groups from a removed interface ipv6: sctp: implement sctp_v6_destroy_sock() arm64: bpf: add 'store immediate' instruction ipv6: kill sk_dst_lock ipv6: sctp: add rcu protection around np->opt net/neighbour: fix crash at dumping device-agnostic proxy entries sctp: use GFP_USER for user-controlled kmalloc sctp: convert sack_needed and sack_generation to bits ipv6: add complete rcu protection around np->opt bpf: fix allocation warnings in bpf maps and integer overflow mvebu: dts: enable IP checksum with jumbo frames for Armada 38x on Port0 net: mvneta: enable setting custom TX IP checksum limit net: mvneta: fix error path for building skb ...
