Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix list tests in netfilter ingress support, from Florian Westphal. 2) Fix reversal of input and output interfaces in ingress hook invocation, from Pablo Neira Ayuso. 3) We have a use after free in r8169, caught by Dave Jones, fixed by Francois Romieu. 4) Splice use-after-free fix in AF_UNIX frmo Hannes Frederic Sowa. 5) Three ipv6 route handling bug fixes from Martin KaFai Lau: a) Don't create clone routes not managed by the fib6 tree b) Don't forget to check expiration of DST_NOCACHE routes. c) Handle rt->dst.from == NULL properly. 6) Several AF_PACKET fixes wrt transport header setting and SKB protocol setting, from Daniel Borkmann. 7) Fix thunder driver crash on shutdown, from Pavel Fedin. 8) Several Mellanox driver fixes (max MTU calculations, use of correct DMA unmap in TX path, etc.) from Saeed Mahameed, Tariq Toukan, Doron Tsur, Achiad Shochat, Eran Ben Elisha, and Noa Osherovich. 9) Several mv88e6060 DSA driver fixes (wrong bit definitions for certain registers, etc.) from Neil Armstrong. 10) Make sure to disable preemption while updating per-cpu stats of ip tunnels, from Jason A. Donenfeld. 11) Various ARM64 bpf JIT fixes, from Yang Shi. 12) Flush icache properly in ARM JITs, from Daniel Borkmann. 13) Fix masking of RX and TX interrupts in ravb driver, from Masaru Nagai. 14) Fix netdev feature propagation for devices not implementing ->ndo_set_features(). From Nikolay Aleksandrov. 15) Big endian fix in vmxnet3 driver, from Shrikrishna Khare. 16) RAW socket code increments incorrect SNMP counters, fix from Ben Cartwright-Cox. 17) IPv6 multicast SNMP counters are bumped twice, fix from Neil Horman. 18) Fix handling of VLAN headers on stacked devices when REORDER is disabled. From Vlad Yasevich. 19) Fix SKB leaks and use-after-free in ipvlan and macvlan drivers, from Sabrina Dubroca. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (83 commits) MAINTAINERS: Update Mellanox's Eth NIC driver entries net/core: revert "net: fix __netdev_update_features return.." and add comment af_unix: take receive queue lock while appending new skb rtnetlink: fix frame size warning in rtnl_fill_ifinfo net: use skb_clone to avoid alloc_pages failure. packet: Use PAGE_ALIGNED macro packet: Don't check frames_per_block against negative values net: phy: Use interrupts when available in NOLINK state phy: marvell: Add support for 88E1540 PHY arm64: bpf: make BPF prologue and epilogue align with ARM64 AAPCS macvlan: fix leak in macvlan_handle_frame ipvlan: fix use after free of skb ipvlan: fix leak in ipvlan_rcv_frame vlan: Do not put vlan headers back on bridge and macvlan ports vlan: Fix untag operations of stacked vlans with REORDER_HEADER off via-velocity: unconditionally drop frames with bad l2 length ipg: Remove ipg driver dl2k: Add support for IP1000A-based cards snmp: Remove duplicate OUTMCAST stat increment net: thunder: Check for driver data in nicvf_remove() ...
