5.10 LTS has backported commit ca43ccf41224 ("dccp/tcp: Avoid negative
sk_forward_alloc by ipv6_pinfo.pktoptions.") and commit 62ec33b44e0f ("net:
Remove WARN_ON_ONCE(sk->sk_forward_alloc) from sk_stream_kill_queues()."),
but these are incomplete. There are some patches that have not been
backported including key commit d38afeec26ed ("tcp/udp: Call
inet6_destroy_sock() in IPv6 sk->sk_destruct().") and commit b5fc29233d28
("inet6: Remove inet6_destroy_sock() in sk->sk_prot->destroy()."). Without
them, there will be some memory leak bugs.
Backport complete patchset for call inet6_destroy_sock() in IPv6
sk->sk_destruct().
Kuniyuki Iwashima (5):
udp: Call inet6_destroy_sock() in setsockopt(IPV6_ADDRFORM).
tcp/udp: Call inet6_destroy_sock() in IPv6 sk->sk_destruct().
inet6: Remove inet6_destroy_sock() in sk->sk_prot->destroy().
dccp: Call inet6_destroy_sock() via sk->sk_destruct().
sctp: Call inet6_destroy_sock() via sk->sk_destruct().
