问题分析：
1、社区修复了一个IPV6_ADDRFORM场景下的内存泄露问题：d38afeec26ed ("tcp/udp: Call inet6_destroy_sock() in IPv6 sk->sk_destruct().")，该问题的修复涉及多个补丁，但是这些补丁不是一个系列，而是分散开的。
2、LTS补丁回合中对上述问题的补丁回合不完整，仅回合了 ca43ccf41224 ("dccp/tcp: Avoid negative sk_forward_alloc by ipv6_pinfo.pktoptions.") 和 62ec33b44e0f ("net: Remove WARN_ON_ONCE(sk->sk_forward_alloc) from sk_stream_kill_queues().")，引入问题的前置补丁和后续补丁都没有回合，LTS分支在该问题场景下会有内存泄露问题，且由于补丁回合不完整引入了更多的IPv6内存泄露问题。
3、版本回合LTS补丁，跟随了LTS上的问题。

完整的补丁集如下：
6431b0f6ff16 ("sctp: Call inet6_destroy_sock() via sk->sk_destruct().")
1651951ebea5 ("dccp: Call inet6_destroy_sock() via sk->sk_destruct().")
62ec33b44e0f net: Remove WARN_ON_ONCE(sk->sk_forward_alloc) from sk_stream_kill_queues().
ca43ccf4122 dccp/tcp: Avoid negative sk_forward_alloc by ipv6_pinfo.pktoptions.
b5fc29233d2 inet6: Remove inet6_destroy_sock() in sk->sk_prot->destroy().
d38afeec26e tcp/udp: Call inet6_destroy_sock() in IPv6 sk->sk_destruct().
21985f43376 udp: Call inet6_destroy_sock() in setsockopt(IPV6_ADDRFORM).
