Merge tag 'net-5.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.13-rc7, including fixes from wireless, bpf,
bluetooth, netfilter and can.
Current release - regressions:
- mlxsw: spectrum_qdisc: Pass handle, not band number to find_class()
to fix modifying offloaded qdiscs
- lantiq: net: fix duplicated skb in rx descriptor ring
- rtnetlink: fix regression in bridge VLAN configuration, empty info
is not an error, bot-generated "fix" was not needed
- libbpf: s/rx/tx/ typo on umem->rx_ring_setup_done to fix umem
creation
Current release - new code bugs:
- ethtool: fix NULL pointer dereference during module EEPROM dump via
the new netlink API
- mlx5e: don't update netdev RQs with PTP-RQ, the special purpose
queue should not be visible to the stack
- mlx5e: select special PTP queue only for SKBTX_HW_TSTAMP skbs
- mlx5e: verify dev is present in get devlink port ndo, avoid a panic
Previous releases - regressions:
- neighbour: allow NUD_NOARP entries to be force GCed
- further fixes for fallout from reorg of WiFi locking (staging:
rtl8723bs, mac80211, cfg80211)
- skbuff: fix incorrect msg_zerocopy copy notifications
- mac80211: fix NULL ptr deref for injected rate info
- Revert "net/mlx5: Arm only EQs with EQEs" it may cause missed IRQs
Previous releases - always broken:
- bpf: more speculative execution fixes
- netfilter: nft_fib_ipv6: skip ipv6 packets from any to link-local
- udp: fix race between close() and udp_abort() resulting in a panic
- fix out of bounds when parsing TCP options before packets are
validated (in netfilter: synproxy, tc: sch_cake and mptcp)
- mptcp: improve operation under memory pressure, add missing
wake-ups
- mptcp: fix double-lock/soft lookup in subflow_error_report()
- bridge: fix races (null pointer deref and UAF) in vlan tunnel
egress
- ena: fix DMA mapping function issues in XDP
- rds: fix memory leak in rds_recvmsg
Misc:
- vrf: allow larger MTUs
- icmp: don't send out ICMP messages with a source address of 0.0.0.0
- cdc_ncm: switch to eth%d interface naming"
