Merge tag 'net-6.1-rc8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from bpf, can and wifi.
Current release - new code bugs:
- eth: mlx5e:
- use kvfree() in mlx5e_accel_fs_tcp_create()
- MACsec, fix RX data path 16 RX security channel limit
- MACsec, fix memory leak when MACsec device is deleted
- MACsec, fix update Rx secure channel active field
- MACsec, fix add Rx security association (SA) rule memory leak
Previous releases - regressions:
- wifi: cfg80211: don't allow multi-BSSID in S1G
- stmmac: set MAC's flow control register to reflect current settings
- eth: mlx5:
- E-switch, fix duplicate lag creation
- fix use-after-free when reverting termination table
Previous releases - always broken:
- ipv4: fix route deletion when nexthop info is not specified
- bpf: fix a local storage BPF map bug where the value's spin lock
field can get initialized incorrectly
- tipc: re-fetch skb cb after tipc_msg_validate
- wifi: wilc1000: fix Information Element parsing
- packet: do not set TP_STATUS_CSUM_VALID on CHECKSUM_COMPLETE
- sctp: fix memory leak in sctp_stream_outq_migrate()
- can: can327: fix potential skb leak when netdev is down
- can: add number of missing netdev freeing on error paths
- aquantia: do not purge addresses when setting the number of rings
- wwan: iosm:
- fix incorrect skb length leading to truncated packet
- fix crash in peek throughput test due to skb UAF"
