Merge tag 'net-6.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from netfiler, xfrm and bluetooth.

  Oddly this includes a fix for a posix clock regression; in our
  previous PR we included a change there as a pre-requisite for
  networking one. That fix proved to be buggy and requires the follow-up
  included here. Thomas suggested we should send it, given we sent the
  buggy patch.

  Current release - regressions:

   - posix-clock: Fix unbalanced locking in pc_clock_settime()

   - netfilter: fix typo causing some targets not to load on IPv6

  Current release - new code bugs:

   - xfrm: policy: remove last remnants of pernet inexact list

  Previous releases - regressions:

   - core: fix races in netdev_tx_sent_queue()/dev_watchdog()

   - bluetooth: fix UAF on sco_sock_timeout

   - eth: hv_netvsc: fix VF namespace also in synthetic NIC
     NETDEV_REGISTER event

   - eth: usbnet: fix name regression

   - eth: be2net: fix potential memory leak in be_xmit()

   - eth: plip: fix transmit path breakage

  Previous releases - always broken:

   - sched: deny mismatched skip_sw/skip_hw flags for actions created by
     classifiers

   - netfilter: bpf: must hold reference on net namespace

   - eth: virtio_net: fix integer overflow in stats

   - eth: bnxt_en: replace ptp_lock with irqsave variant

   - eth: octeon_ep: add SKB allocation failures handling in
     __octep_oq_process_rx()
