* lp1820068.patch: don't skip read cache when options are set (LP: #1820068) * reenable ubuntu/parser-conf-no-expr-simplify.patch -- Jamie Strandboge <[email protected]> Thu, 06 Jun 2019 21:46:34 +0000 ** Changed in: apparmor (Ubuntu Eoan) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/1820068 Title: specifying -O no-expr-simplify results in cache miss Status in AppArmor: Fix Released Status in apparmor package in Ubuntu: Fix Released Status in apparmor source package in Disco: In Progress Status in apparmor source package in Eoan: Fix Released Bug description: With 2.13.2 and the most recent testsuite patches from the 2.13 branch, I find that the cache works correctly when no options are specified. Eg # setup $ mkdir -p /tmp/aa/cache /tmp/aa/profiles $ cp /etc/apparmor.d/sbin.dhclient /tmp/aa/profiles/ # no options, no cache, expect a miss and to write $ /sbin/apparmor_parser -k --write-cache --cache-loc=/tmp/aa/cache --skip-kernel-load --add -- /tmp/aa/profiles Cache: added primary location '/tmp/aa/cache' Cache miss: /tmp/aa/profiles/sbin.dhclient Wrote cache: /tmp/aa/cache/26b63962.0/sbin.dhclient # no options, cache, expect a hit $ /sbin/apparmor_parser -k --write-cache --cache-loc=/tmp/aa/cache --skip-kernel-load --add -- /tmp/aa/profiles Cache: added primary location '/tmp/aa/cache' Cache hit: /tmp/aa/cache/26b63962.0/sbin.dhclient # reset $ rm -rf /tmp/aa/cache/* # options, no cache, expect a miss and to write $ /sbin/apparmor_parser -k --write-cache --cache-loc=/tmp/aa/cache --skip-kernel-load -O no-expr-simplify --add -- /tmp/aa/profiles Cache: added primary location '/tmp/aa/cache' Cache miss: /tmp/aa/profiles/sbin.dhclient Wrote cache: /tmp/aa/cache/26b63962.0/sbin.dhclient # options, cache, expect a hit $ /sbin/apparmor_parser -k --write-cache --cache-loc=/tmp/aa/cache --skip-kernel-load -O no-expr-simplify --add -- /tmp/aa/profiles Cache: added primary location '/tmp/aa/cache' Cache miss: /tmp/aa/profiles/sbin.dhclient # SHOULD BE A HIT Wrote cache: /tmp/aa/cache/26b63962.0/sbin.dhclient Same thing happens if omitting -O no-expr-simplify but add Optimize =no-expr-simplify to /etc/apparmor/parser.conf.
