From c3083d9d9e5860c365e93b1e96aa65613fa829fb Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Wed, 4 Apr 2012 13:47:11 -0400 Subject: SELinux: if sel_make_bools errors don't leave inconsistent state commit 154c50ca4eb9ae472f50b6a481213e21ead4457d upstream. We reset the bool names and values array to NULL, but do not reset the number of entries in these arrays to 0. If we error out and then get back into this function we will walk these NULL pointers based on the belief that they are non-zero length.
