Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "First batch of fixes in the new merge window: 1) Double dst_cache free in act_tunnel_key, from Wenxu. 2) Avoid NULL deref in IN_DEV_MFORWARD() by failing early in the ip_route_input_rcu() path, from Paolo Abeni. 3) Fix appletalk compile regression, from Arnd Bergmann. 4) If SLAB objects reach the TCP sendpage method we are in serious trouble, so put a debugging check there. From Vasily Averin. 5) Memory leak in hsr layer, from Mao Wenan. 6) Only test GSO type on GSO packets, from Willem de Bruijn. 7) Fix crash in xsk_diag_put_umem(), from Eric Dumazet. 8) Fix VNIC mailbox length in nfp, from Dirk van der Merwe. 9) Fix race in ipv4 route exception handling, from Xin Long. 10) Missing DMA memory barrier in hns3 driver, from Jian Shen. 11) Use after free in __tcf_chain_put(), from Vlad Buslov. 12) Handle inet_csk_reqsk_queue_add() failures, from Guillaume Nault. 13) Return value correction when ip_mc_may_pull() fails, from Eric Dumazet. 14) Use after free in x25_device_event(), also from Eric" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (72 commits) gro_cells: make sure device is up in gro_cells_receive() vxlan: test dev->flags & IFF_UP before calling gro_cells_receive() net/x25: fix use-after-free in x25_device_event() isdn: mISDNinfineon: fix potential NULL pointer dereference net: hns3: fix to stop multiple HNS reset due to the AER changes ip: fix ip_mc_may_pull() return value net: keep refcount warning in reqsk_free() net: stmmac: Avoid one more sometimes uninitialized Clang warning net: dsa: mv88e6xxx: Set correct interface mode for CPU/DSA ports rxrpc: Fix client call queueing, waiting for channel tcp: handle inet_csk_reqsk_queue_add() failures net: ethernet: sun: Zero initialize class in default case in niu_add_ethtool_tcam_entry 8139too : Add support for U.S. Robotics USR997901A 10/100 Cardbus NIC fou, fou6: avoid uninit-value in gue_err() and gue6_err() net: sched: fix potential use-after-free in __tcf_chain_put() vhost: silence an unused-variable warning vsock/virtio: fix kernel panic from virtio_transport_reset_no_sock connector: fix unsafe usage of ->real_parent vxlan: do not need BH again in vxlan_cleanup() net: hns3: add dma_rmb() for rx description ...
