inet: Fix __inet_inherit_port() to correctly increment bsockets and num_owners
inet sockets corresponding to passive connections are added to the bind hash using ___inet_inherit_port(). These sockets are later removed from the bind hash using __inet_put_port(). These two functions are not exactly symmetrical. __inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas ___inet_inherit_port() does not increment them. This results in both of these going to -ve values. This patch fixes this by calling inet_bind_hash() from ___inet_inherit_port(), which does the right thing. 'bsockets' and 'num_owners' were introduced by commit a9d8f9110d7e953c (inet: Allowing more than 64k connections and heavily optimize bind(0)) Signed-off-by: Nagendra Singh Tomar <tomer_iisc@yahoo.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Evgeniy Polyakov <zbr@ioremap.net> Signed-off-by: David S.
