Merge tag 'net-6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Including fixes from wifi, netfilter and can. A handful of awaited fixes here - revert of the FEC changes, bluetooth fix, fixes for iwlwifi spew. We added a warning in PHY/MDIO code which is triggering on a couple of platforms in a false-positive-ish way. If we can't iron that out over the week we'll drop it and re-add for 6.1. I've added a new "follow up fixes" section for fixes to fixes in 6.0-rcs but it may actually give the false impression that those are problematic or that more testing time would have caught them. So likely a one time thing. Follow up fixes: - nf_tables_addchain: fix nft_counters_enabled underflow - ebtables: fix memory leak when blob is malformed - nf_ct_ftp: fix deadlock when nat rewrite is needed Current release - regressions: - Revert "fec: Restart PPS after link state change" and the related "net: fec: Use a spinlock to guard `fep->ptp_clk_on`" - Bluetooth: fix HCIGETDEVINFO regression - wifi: mt76: fix 5 GHz connection regression on mt76x0/mt76x2 - mptcp: fix fwd memory accounting on coalesce - rwlock removal fall out: - ipmr: always call ip{,6}_mr_forward() from RCU read-side critical section - ipv6: fix crash when IPv6 is administratively disabled - tcp: read multiple skbs in tcp_read_skb() - mdio_bus_phy_resume state warning fallout: - eth: ravb: fix PHY state warning splat during system resume - eth: sh_eth: fix PHY state warning splat during system resume Current release - new code bugs: - wifi: iwlwifi: don't spam logs with NSS>2 messages - eth: mtk_eth_soc: enable XDP support just for MT7986 SoC Previous releases - regressions: - bonding: fix NULL deref in bond_rr_gen_slave_id - wifi: iwlwifi: mark IWLMEI as broken Previous releases - always broken: - nf_conntrack helpers: - irc: tighten matching on DCC message - sip: fix ct_sip_walk_headers - osf: fix possible bogus match in nf_osf_find() - ipvlan: fix out-of-bound bugs caused by unset skb->mac_header - core: fix flow symmetric hash - bonding, team: unsync device addresses on ndo_stop - phy: micrel: fix shared interrupt on LAN8814" * tag 'net-6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (83 commits) selftests: forwarding: add shebang for sch_red.sh bnxt: prevent skb UAF after handing over to PTP worker net: marvell: Fix refcounting bugs in prestera_port_sfp_bind() net: sched: fix possible refcount leak in tc_new_tfilter() net: sunhme: Fix packet reception for len < RX_COPY_THRESHOLD udp: Use WARN_ON_ONCE() in udp_read_skb() selftests: bonding: cause oops in bond_rr_gen_slave_id bonding: fix NULL deref in bond_rr_gen_slave_id net: phy: micrel: fix shared interrupt on LAN8814 net/smc: Stop the CLC flow if no link to map buffers on ice: Fix ice_xdp_xmit() when XDP TX queue number is not sufficient net: atlantic: fix potential memory leak in aq_ndev_close() can: gs_usb: gs_usb_set_phys_id(): return with error if identify is not supported can: gs_usb: gs_can_open(): fix race dev->can.state condition can: flexcan: flexcan_mailbox_read() fix return value for drop = true net: sh_eth: Fix PHY state warning splat during system resume net: ravb: Fix PHY state warning splat during system resume netfilter: nf_ct_ftp: fix deadlock when nat rewrite is needed netfilter: ebtables: fix memory leak when blob is malformed netfilter: nf_tables: fix percpu memory leak at nf_tables_addchain() ...
