Merge tag 'net-6.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bluetooth, WiFi and netfilter.

  We have one outstanding issue with the stmmac driver, which may be a
  LOCKDEP false positive, not a blocker.

  Current release - regressions:

   - netfilter: nf_tables: re-allow NFPROTO_INET in
     nft_(match/target)_validate()

   - eth: ionic: fix error handling in PCI reset code

  Current release - new code bugs:

   - eth: stmmac: complete meta data only when enabled, fix null-deref

   - kunit: fix again checksum tests on big endian CPUs

  Previous releases - regressions:

   - veth: try harder when allocating queue memory

   - Bluetooth:
      - hci_bcm4377: do not mark valid bd_addr as invalid
      - hci_event: fix handling of HCI_EV_IO_CAPA_REQUEST

  Previous releases - always broken:

   - info leak in __skb_datagram_iter() on netlink socket

   - mptcp:
      - map v4 address to v6 when destroying subflow
      - fix potential wake-up event loss due to sndbuf auto-tuning
      - fix double-free on socket dismantle

   - wifi: nl80211: reject iftype change with mesh ID change

   - fix small out-of-bound read when validating netlink be16/32 types

   - rtnetlink: fix error logic of IFLA_BRIDGE_FLAGS writing back

   - ipv6: fix potential "struct net" ref-leak in inet6_rtm_getaddr()

   - ip_tunnel: prevent perpetual headroom growth with huge number of
     tunnels on top of each other

   - mctp: fix skb leaks on error paths of mctp_local_output()

   - eth: ice: fixes for DPLL state reporting

   - dpll: rely on rcu for netdev_dpll_pin() to prevent UaF

   - eth: dpaa: accept phy-interface-type = '10gbase-r' in the device
     tree"

* tag 'net-6.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (73 commits)
  dpll: fix build failure due to rcu_dereference_check() on unknown type

  tls: fix peeking with sync+async decryption
  tls: decrement decrypt_pending if no async completion will be called
  gtp: fix use-after-free and null-ptr-deref in gtp_newlink()
  net: hsr: Use correct offset for HSR TLV values in supervisory HSR frames
  igb: extend PTP timestamp adjustments to i211
  rtnetlink: fix error logic of IFLA_BRIDGE_FLAGS writing back
  tools: ynl: fix handling of multiple mcast groups
  selftests: netfilter: add bridge conntrack + multicast test case
  netfilter: bridge: confirm multicast packets before passing them up the stack
  netfilter: nf_tables: allow NFPROTO_INET in nft_(match/target)_validate()
  Bluetooth: qca: Fix triggering coredump implementation
  Bluetooth: hci_qca: Set BDA quirk bit if fwnode exists in DT
  Bluetooth: qca: Fix wrong event type for patch config command
  Bluetooth: Enforce validation on max value of connection interval
