Merge tag 'net-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth and netfilter.
Slim pickings this time, probably a combination of summer, DevConf.cz,
and the end of first half of the year at corporations.
Current release - regressions:
- Revert "igc: fix a log entry using uninitialized netdev", it traded
lack of netdev name in a printk() for a crash
Previous releases - regressions:
- Bluetooth: L2CAP: fix rejecting L2CAP_CONN_PARAM_UPDATE_REQ
- geneve: fix incorrectly setting lengths of inner headers in the
skb, confusing the drivers and causing mangled packets
- sched: initialize noop_qdisc owner to avoid false-positive
recursion detection (recursing on CPU 0), which bubbles up to user
space as a sendmsg() error, while noop_qdisc should silently drop
- netdevsim: fix backwards compatibility in nsim_get_iflink()
Previous releases - always broken:
- netfilter: ipset: fix race between namespace cleanup and gc in the
list:set type"
