Merge tag 'net-6.7-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni:
"Including fixes from WiFi and bpf.
Current release - regressions:
- bpf: syzkaller found null ptr deref in unix_bpf proto add
- eth: i40e: fix ST code value for clause 45
Previous releases - regressions:
- core: return error from sk_stream_wait_connect() if sk_wait_event()
fails
- ipv6: revert remove expired routes with a separated list of routes
- wifi rfkill:
- set GPIO direction
- fix crash with WED rx support enabled
- bluetooth:
- fix deadlock in vhci_send_frame
- fix use-after-free in bt_sock_recvmsg
- eth: mlx5e: fix a race in command alloc flow
- eth: ice: fix PF with enabled XDP going no-carrier after reset
- eth: bnxt_en: do not map packet buffers twice
Previous releases - always broken:
- core:
- check vlan filter feature in vlan_vids_add_by_dev() and
vlan_vids_del_by_dev()
- check dev->gso_max_size in gso_features_check()
- mptcp: fix inconsistent state on fastopen race
- phy: skip LED triggers on PHYs on SFP modules
- eth: mlx5e:
- fix double free of encap_header
- fix slab-out-of-bounds in mlx5_query_nic_vport_mac_list()"
