Pull networking fixes from David Miller: "Several fixes here. Basically split down the line between newly introduced regressions and long existing problems: 1) Double free in tipc_enable_bearer(), from Cong Wang. 2) Many fixes to nf_conncount, from Florian Westphal. 3) op->get_regs_len() can throw an error, check it, from Yunsheng Lin. 4) Need to use GFP_ATOMIC in *_add_hash_mac_address() of fsl/fman driver, from Scott Wood. 5) Inifnite loop in fib_empty_table(), from Yue Haibing. 6) Use after free in ax25_fillin_cb(), from Cong Wang. 7) Fix socket locking in nr_find_socket(), also from Cong Wang. 8) Fix WoL wakeup enable in r8169, from Heiner Kallweit. 9) On 32-bit sock->sk_stamp is not thread-safe, from Deepa Dinamani. 10) Fix ptr_ring wrap during queue swap, from Cong Wang. 11) Missing shutdown callback in hinic driver, from Xue Chaojing. 12) Need to return NULL on error from ip6_neigh_lookup(), from Stefano Brivio. 13) BPF out of bounds speculation fixes from Daniel Borkmann" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (57 commits) ipv6: Consider sk_bound_dev_if when binding a socket to an address ipv6: Fix dump of specific table with strict checking bpf: add various test cases to selftests bpf: prevent out of bounds speculation on pointer arithmetic bpf: fix check_map_access smin_value test when pointer contains offset bpf: restrict unknown scalars of mixed signed bounds for unprivileged bpf: restrict stack pointer arithmetic for unprivileged bpf: restrict map value pointer arithmetic for unprivileged bpf: enable access to ax register also from verifier rewrite bpf: move tmp variable into ax register in interpreter bpf: move {prev_,}insn_idx into verifier env isdn: fix kernel-infoleak in capi_unlocked_ioctl ipv6: route: Fix return value of ip6_neigh_lookup() on neigh_create() error net/hamradio/6pack: use mod_timer() to rearm timers net-next/hinic:add shutdown callback net: hns3: call hns3_nic_net_open() while doing HNAE3_UP_CLIENT ip: validate header length on virtual device xmit tap: call skb_probe_transport_header after setting skb->dev ptr_ring: wrap back ->producer in __ptr_ring_swap_queue() net: rds: remove unnecessary NULL check ...
