Merge tag 'net-7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from Wireless, IPsec, Netfilter and Bluetooth.

  Current release - new code bugs:

    - netfilter: flowtable: use correct direction to set up tunnel route

  Previous releases - regressions:

    - wifi:
       - mac80211:
          - free AP_VLAN bc_buf SKBs outside IRQ lock
          - defer link RX stats percpu free to RCU
          - fix double free on alloc failure
       - cfg80211: convert pmsr_free_wk to wiphy_work to fix deadlock

    - ipv4: free fib_alias with kfree_rcu() on insert error path

    - sched: act_tunnel_key: Defer dst_release to RCU callback

    - xfrm: fix sk_dst_cache double-free in xfrm_user_policy()

    - bluetooth: fix locking in unpair_device/disconnect_sync

    - can: add locking for raw flags bitfield

    - openvswitch: reject oversized nested action attrs

    - eth:
       - bnxt_en: handle partially initialized auxiliary devices
       - ppp: defer channel free to an RCU grace period to fix UAF

  Previous releases - always broken:

    -  netfilter: xt_nat: reject unsupported target families

    -  wifi:
        - brcmfmac: fix heap overflow on a short auth frame
        - cfg80211: add missing FTM API validation

    - xfrm:
       - reject optional IPTFS templates in outbound policies
       - policy: preallocate inexact bins before xfrm_hash_rebuild reinsert

    - bluetooth: revalidate LOAD_CONN_PARAM queued update

    - can: fix lockless bound/ifindex race and silent RX_SETUP failure

    - eth: mlx5: free mlx5_st_idx_data on final dealloc"
