From b5dfd8075bc26636d11c3d8888940198afbf5112 Mon Sep 17 00:00:00 2001 From: Casey Schaufler Date: Tue, 22 Oct 2013 11:47:45 -0700 Subject: [PATCH] Smack: Ptrace access check mode When the ptrace security hooks were split the addition of a mode parameter was not taken advantage of in the Smack ptrace access check. This changes the access check from always looking for read and write access to using the passed mode. This will make use of /proc much happier.
