Merge tag 'net-6.7-rc9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from wireless and netfilter.
We haven't accumulated much over the break. If it wasn't for the
uninterrupted stream of fixes for Intel drivers this PR would be very
slim. There was a handful of user reports, however, either they stood
out because of the lower traffic or users have had more time to test
over the break. The ones which are v6.7-relevant should be wrapped up.
Current release - regressions:
- Revert "net: ipv6/addrconf: clamp preferred_lft to the minimum
required", it caused issues on networks where routers send prefixes
with preferred_lft=0
- wifi:
- iwlwifi: pcie: don't synchronize IRQs from IRQ, prevent deadlock
- mac80211: fix re-adding debugfs entries during reconfiguration
Current release - new code bugs:
- tcp: print AO/MD5 messages only if there are any keys
Previous releases - regressions:
- virtio_net: fix missing dma unmap for resize, prevent OOM
Previous releases - always broken:
- mptcp: prevent tcp diag from closing listener subflows
- nf_tables:
- set transport header offset for egress hook, fix IPv4 mangling
- skip set commit for deleted/destroyed sets, avoid double deactivation
- nat: make sure action is set for all ct states, fix openvswitch
matching on ICMP packets in related state
- eth: mlxbf_gige: fix receive hang under heavy traffic
- eth: r8169: fix PCI error on system resume for RTL8168FP
- net: add missing getsockopt(SO_TIMESTAMPING_NEW) and cmsg handling"
