From d384b0a1a35f87f0ad70c29518f98f922b1c15cb Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Thu, 26 Jan 2012 16:29:23 -0800 Subject: AppArmor: export known rlimit names/value mappings in securityfs Since the parser needs to know which rlimits are known to the kernel, export the list via a mask file in the "rlimit" subdirectory in the securityfs "features" directory.
