Don't you need to test for fullsock? Do you mean something like below?
It should be safe to call sock_net_uid on any type of socket
(including NULL). sk_uid was added to struct sock in 86741ec25462
("net: core: Add a UID field to struct sock.")
Hmm, maybe I'm missing something, but then shouldn't this sit in
struct sock_common for being 'safe'? F.e. struct inet_timewait_sock
wouldn't have it ...
