Code Issues Projects Releases Wiki Activity

Networking fixes for 5.17-final, including fixes from netfilter, ipsec, 

and wireless.
 
 Current release - regressions:
 
  - Revert "netfilter: nat: force port remap to prevent shadowing
    well-known ports", restore working conntrack on asymmetric paths
 
  - Revert "ath10k: drop beacon and probe response which leak from
    other channel", restore working AP and mesh mode on QCA9984
 
  - eth: intel: fix hang during reboot/shutdown
 
 Current release - new code bugs:
 
  - netfilter: nf_tables: disable register tracking, it needs more
    work to cover all corner cases
 
 Previous releases - regressions:
 
  - ipv6: fix skb_over_panic in __ip6_append_data when (admin-only)
    extension headers get specified
 
  - esp6: fix ESP over TCP/UDP, interpret ipv6_skip_exthdr's return
    value more selectively
 
  - bnx2x: fix driver load failure when FW not present in initrd
 
 Previous releases - always broken:
 
  - vsock: stop destroying unrelated sockets in nested virtualization
 
  - packet: fix slab-out-of-bounds access in packet_recvmsg()
 
 Misc:
 
  - add Paolo Abeni to networking maintainers!
