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"
