Merge tag 'net-6.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter.
As Paolo promised we continue to hammer out issues in our selftests.
This is not the end but probably the peak.
Current release - regressions:
- smc: fix incorrect SMC-D link group matching logic
Current release - new code bugs:
- eth: bnxt: silence WARN() when device skips a timestamp, it happens
Previous releases - regressions:
- ipmr: fix null-deref when forwarding mcast packets
- conntrack: evaluate window negotiation only for packets in the
REPLY direction, otherwise SYN retransmissions trigger incorrect
window scale negotiation
- ipset: fix performance regression in swap operation
Previous releases - always broken:
- tcp: add sanity checks to types of pages getting into the rx
zerocopy path, we only support basic NIC -> user, no page cache
pages etc.
- ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()
- nt_tables: more input sanitization changes
- dsa: mt7530: fix 10M/100M speed on MediaTek MT7988 switch
- bridge: mcast: fix loss of snooping after long uptime, jiffies do
wrap on 32bit
- xen-netback: properly sync TX responses, protect with locking
- phy: mediatek-ge-soc: sync calibration values with MediaTek SDK,
increase connection stability
- eth: pds: fixes for various teardown, and reset races
Misc:
- hsr: silence WARN() if we can't alloc supervision frame, it
happens"
