Subject: [PATCH 08/13] rpc_soc.c: resource_leak
Date: Fri,  7 Sep 2018 14:01:46 -0400	[thread overview]
Message-ID: <20180907180151.178872-9-steved@redhat.com> (raw)
In-Reply-To: <20180907180151.178872-1-steved@redhat.com>

Variable "localhandle" going out of scope leaks the storage it points to.
Returning without closing handle "sock" leaks it.
