Subject: sctp: fix /proc/net/sctp/ memory leak
From: Tommi Rantala <[email protected]>
[ Upstream commit 0da9a0c2638c8476b4a5021841912f249e3187dc ]
Commit 13d782f ("sctp: Make the proc files per network namespace.")
changed the /proc/net/sctp/ struct file_operations opener functions to
use single_open_net() and seq_open_net().
Avoid leaking memory by using single_release_net() and seq_release_net()
as the release functions.
Discovered with Trinity (the syscall fuzzer).
