Subject: [PATCH ipsec net] xfrm: put policies when reusing pcpu xdst entry
Date: Mon, 11 Dec 2017 18:23:09 +0100 [thread overview]
Message-ID: <20171211172309.29427-1-fw@strlen.de> (raw)
We need to put the policies when re-using the pcpu xdst entry, else
this leaks the reference.
Fixes: ec30d78c14a813db39a647b6a348b428 ("xfrm: add xdst pcpu cache")
