parentpacket: propagate sock_cmsg_send() error (diff)
Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix memory leak in nftables, from Liping Zhang. 2) Need to check result of vlan_insert_tag() in batman-adv otherwise we risk NULL skb derefs, from Sven Eckelmann. 3) Check for dev_alloc_skb() failures in cfg80211, from Gregory Greenman. 4) Handle properly when we have ppp_unregister_channel() happening in parallel with ppp_connect_channel(), from WANG Cong. 5) Fix DCCP deadlock, from Eric Dumazet. 6) Bail out properly in UDP if sk_filter() truncates the packet to be smaller than even the space that the protocol headers need. From Michal Kubecek. 7) Similarly for rose, dccp, and sctp, from Willem de Bruijn. 8) Make TCP challenge ACKs less predictable, from Eric Dumazet. 9) Fix infinite loop in bgmac_dma_tx_add() from Florian Fainelli. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (65 commits) packet: propagate sock_cmsg_send() error net/mlx5e: Fix del vxlan port command buffer memset packet: fix second argument of sock_tx_timestamp() net: switchdev: change ageing_time type to clock_t Update maintainer for EHEA driver. net/mlx4_en: Add resilience in low memory systems net/mlx4_en: Move filters cleanup to a proper location sctp: load transport header after sk_filter net/sched/sch_htb: clamp xstats tokens to fit into 32-bit int net: cavium: liquidio: Avoid dma_unmap_single on uninitialized ndata net: nb8800: Fix SKB leak in nb8800_receive() et131x: Fix logical vs bitwise check in et131x_tx_timeout() vlan: use a valid default mtu value for vlan over macsec net: bgmac: Fix infinite loop in bgmac_dma_tx_add() mlxsw: spectrum: Prevent invalid ingress buffer mapping mlxsw: spectrum: Prevent overwrite of DCB capability fields mlxsw: spectrum: Don't emit errors when PFC is disabled mlxsw: spectrum: Indicate support for autonegotiation mlxsw: spectrum: Force link training according to admin state r8152: add MODULE_VERSION ...
