Merge tag 'net-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from bpf and netfilter.
Previous releases - regressions:
- Revert "net: rtnetlink: Enslave device before bringing it up",
breaks the case inverse to the one it was trying to fix
- net: dsa: fix oob access in DSA's netdevice event handler
dereference netdev_priv() before check its a DSA port
- sched: track device in tcf_block_get/put_ext() only for clsact
binder types
- net: tls, fix WARNING in __sk_msg_free when record becomes full
during splice and MORE hint set
- sfp-bus: fix SFP mode detect from bitrate
- drv: stmmac: prevent DSA tags from breaking COE
Previous releases - always broken:
- bpf: fix no forward progress in in bpf_iter_udp if output buffer is
too small
- bpf: reject variable offset alu on registers with a type of
PTR_TO_FLOW_KEYS to prevent oob access
- netfilter: tighten input validation
- net: add more sanity check in virtio_net_hdr_to_skb()
- rxrpc: fix use of Don't Fragment flag on RESPONSE packets, avoid
infinite loop
- amt: do not use the portion of skb->cb area which may get clobbered
- mptcp: improve validation of the MPTCPOPT_MP_JOIN MCTCP option
Misc:
- spring cleanup of inactive maintainers"
