Pull more networking updates from David Miller: 1) If a VXLAN interface is created with no groups, we can crash on reception of packets. Fix from Mike Rapoport. 2) Missing includes in CPTS driver, from Alexei Starovoitov. 3) Fix string validations in isdnloop driver, from YOSHIFUJI Hideaki and Dan Carpenter. 4) Missing irq.h include in bnxw2x, enic, and qlcnic drivers. From Josh Boyer. 5) AF_PACKET transmit doesn't statistically count TX drops, from Daniel Borkmann. 6) Byte-Queue-Limit enabled drivers aren't handled properly in AF_PACKET transmit path, also from Daniel Borkmann. Same problem exists in pktgen, and Daniel fixed it there too. 7) Fix resource leaks in driver probe error paths of new sxgbe driver, from Francois Romieu. 8) Truesize of SKBs can gradually get more and more corrupted in NAPI packet recycling path, fix from Eric Dumazet. 9) Fix uniprocessor netfilter build, from Florian Westphal. In the longer term we should perhaps try to find a way for ARRAY_SIZE() to work even with zero sized array elements. 10) Fix crash in netfilter conntrack extensions due to mis-estimation of required extension space. From Andrey Vagin. 11) Since we commit table rule updates before trying to copy the counters back to userspace (it's the last action we perform), we really can't signal the user copy with an error as we are beyond the point from which we can unwind everything. This causes all kinds of use after free crashes and other mysterious behavior. From Thomas Graf. 12) Restore previous behvaior of div/mod by zero in BPF filter processing. From Daniel Borkmann. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (38 commits) net: sctp: wake up all assocs if sndbuf policy is per socket isdnloop: several buffer overflows netdev: remove potentially harmful checks pktgen: fix xmit test for BQL enabled devices net/at91_ether: avoid NULL pointer dereference tipc: Let tipc_release() return 0 at86rf230: fix MAX_CSMA_RETRIES parameter mac802154: fix duplicate #include headers sxgbe: fix duplicate #include headers net: filter: be more defensive on div/mod by X==0 netfilter: Can't fail and free after table replacement xen-netback: Trivial format string fix net: bcmgenet: Remove unnecessary version.h inclusion net: smc911x: Remove unused local variable bonding: Inactive slaves should keep inactive flag's value netfilter: nf_tables: fix wrong format in request_module() netfilter: nf_tables: set names cannot be larger than 15 bytes netfilter: nf_conntrack: reserve two bytes for nf_ct_ext->len netfilter: Add {ipt,ip6t}_osf aliases for xt_osf netfilter: x_tables: allow to use cgroup match for LOCAL_IN nf hooks ...
