Merge tag 'net-5.15-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from WiFi (mac80211), and BPF.

  Current release - regressions:

   - skb_expand_head: adjust skb->truesize to fix socket memory
     accounting

   - mptcp: fix corrupt receiver key in MPC + data + checksum

  Previous releases - regressions:

   - multicast: calculate csum of looped-back and forwarded packets

   - cgroup: fix memory leak caused by missing cgroup_bpf_offline

   - cfg80211: fix management registrations locking, prevent list
     corruption

   - cfg80211: correct false positive in bridge/4addr mode check

   - tcp_bpf: fix race in the tcp_bpf_send_verdict resulting in reusing
     previous verdict

  Previous releases - always broken:

   - sctp: enhancements for the verification tag, prevent attackers from
     killing SCTP sessions

   - tipc: fix size validations for the MSG_CRYPTO type

   - mac80211: mesh: fix HE operation element length check, prevent out
     of bound access

   - tls: fix sign of socket errors, prevent positive error codes being
     reported from read()/write()

   - cfg80211: scan: extend RCU protection in
     cfg80211_add_nontrans_list()

   - implement ->sock_is_readable() for UDP and AF_UNIX, fix poll() for
     sockets in a BPF sockmap

   - bpf: fix potential race in tail call compatibility check resulting
     in two operations which would make the map incompatible succeeding

   - bpf: prevent increasing bpf_jit_limit above max

   - bpf: fix error usage of map_fd and fdget() in generic batch update

   - phy: ethtool: lock the phy for consistency of results

   - prevent infinite while loop in skb_tx_hash() when Tx races with
     driver reconfiguring the queue <> traffic class mapping

   - usbnet: fixes for bad HW conjured by syzbot

   - xen: stop tx queues during live migration, prevent UAF

   - net-sysfs: initialize uid and gid before calling
     net_ns_get_ownership

   - mlxsw: prevent Rx stalls under memory pressure"
