Merge tag 'net-6.2-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf, can and netfilter.

  Current release - regressions:

   - phy: fix null-deref in phy_attach_direct

   - mac802154: fix possible double free upon parsing error

  Previous releases - regressions:

   - bpf: preserve reg parent/live fields when copying range info,
     prevent mis-verification of programs as safe

   - ip6: fix GRE tunnels not generating IPv6 link local addresses

   - phy: dp83822: fix null-deref on DP83825/DP83826 devices

   - sctp: do not check hb_timer.expires when resetting hb_timer

   - eth: mtk_sock: fix SGMII configuration after phylink conversion

  Previous releases - always broken:

   - eth: xdp: execute xdp_do_flush() before napi_complete_done()

   - skb: do not mix page pool and page referenced frags in GRO

   - bpf:
      - fix a possible task gone issue with bpf_send_signal[_thread]()
      - fix an off-by-one bug in bpf_mem_cache_idx() to select the right
        cache
      - add missing btf_put to register_btf_id_dtor_kfuncs
      - sockmap: fon't let sock_map_{close,destroy,unhash} call itself

   - gso: fix null-deref in skb_segment_list()

   - mctp: purge receive queues on sk destruction

   - fix UaF caused by accept on already connected socket in exotic
     socket families

   - tls: don't treat list head as an entry in tls_is_tx_ready()

   - netfilter: br_netfilter: disable sabotage_in hook after first
     suppression

   - wwan: t7xx: fix runtime PM implementation

  Misc:

   - MAINTAINERS: spring cleanup of networking maintainers"
