From e6e0871cce2ae04f5790543ad2f4ec36b23260ba Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Wed, 1 Aug 2007 11:12:59 -0400 Subject: [PATCH] Net/Security: fix memory leaks from security_secid_to_secctx() The security_secid_to_secctx() function returns memory that must be freed by a call to security_release_secctx() which was not always happening. This patch fixes two of these problems (all that I could find in the kernel source at present).
