Eric Dumazet 0cafd77dcd net: add a refcount tracker for kernel sockets ... Commit ffa84b5ffb ("net: add netns refcount tracker to struct sock") added a tracker to sockets, but did not track kernel sockets. We still have syzbot reports hinting about netns being destroyed while some kernel TCP sockets had not been dismantled. This patch tracks kernel sockets, and adds a ref_tracker_dir_print() call to net_free() right before the netns is freed. Normally, each layer is responsible for properly releasing its kernel sockets before last call to net_free(). This debugging facility is enabled with CONFIG_NET_NS_REFCNT_TRACKER=y Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Kuniyuki Iwashima <kuniyu@amazon.com> Tested-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: David S.
