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"
