Subject: net: do not call sock_put() on TIMEWAIT sockets
From: Eric Dumazet <edumazet@xxxxxxxxxx>
[ Upstream commit 80ad1d61e72d626e30ebe8529a0455e660ca4693 ]
commit 3ab5aee7fe84 ("net: Convert TCP & DCCP hash tables to use RCU /
hlist_nulls") incorrectly used sock_put() on TIMEWAIT sockets.
We should instead use inet_twsk_put()
