Subject: [PATCH 0/6] selinux: Assorted simplifications and cleanups
Date: Thu, 16 Jan 2020 13:04:33 +0100
Message-ID: <20200116120439.303034-1-omosnace@redhat.com> (raw)

This series contains some simplifications that I discovered while
working on another patch. I believe they also save some run time
(although not in any perf-critical paths) and some memory overhead.

The first patch is a cleanup in security_load_policy() that avoids a
pointless allocation during initial policy load. The rest are
cleanups/simplifications of the booleans-related code - mostly
converting linked lists to arrays.

Ondrej Mosnacek (6):
  selinux: do not allocate ancillary buffer on first load
  selinux: simplify security_preserve_bools()
  selinux: convert cond_list to array
  selinux: convert cond_av_list to array
  selinux: convert cond_expr to array
  selinux: generalize evaluate_cond_node()
