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()
Misc:
- MAINTAINERS: add Simon as an official reviewer"
