Bug Description

SRU

1. Impact: affects monitoring systems that depend on the exit code of status

2. Bug has not been fixed in the development branch (natty is not open)

3. Patch is a 2 character patch to adjust the path to aa-status from /usr/bin to /usr/sbin in two places

4. TEST CASE
$ sudo /etc/init.d/apparmor teardown
$ sudo /etc/init.d/apparmor status && echo "FAIL (exited with $?)"

5. Regression potential is extremely low, as the patch only adjusts the path for a command in the initscript that is not used as part of the boot or shutdown process

Binary package hint: apparmor

# lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04

# apt-cache policy apparmor apparmor-utils
apparmor:
  Installed: 2.5-0ubuntu3
  Candidate: 2.5-0ubuntu3
[...]
apparmor-utils:
  Installed: 2.5-0ubuntu3
  Candidate: 2.5-0ubuntu3

Expected Results:
  Running "/etc/init.d/apparmor status" after stopping apparmor should have a non-zero exit status to indicate that apparmor is not enabled.

Actual Results:
  Running "/etc/init.d/apparmor status" always result in an exit code of 0, even after running "/etc/init.d/apparmor stop".

Looks like this is caused by a simple error in /etc/init.d/apparmor. The status function looks for the existence of /usr/bin/aa-status. However, aa-status is in /usr/sbin, not /usr/bin. So the status function falls back to displaying the contents of /sys/kernel/sercurity/apparmor/profiles and uses the exit status of the cat command as its exit status.

If the init script correctly calls aa-status, the status function has a more useful exit status.

This bug was fixed in the package apparmor - 2.5.1-0ubuntu0.10.04.1

---------------
apparmor (2.5.1-0ubuntu0.10.04.1) lucid-proposed; urgency=low

  * Backport 2.5.1-0ubuntu0.10.10.1 from maverick for userspace tools to work
    with newer kernels (LP: #660077)
    NOTE: user-tmp now uses 'owner' match, so non-default profiles will have
    to be adjusted when 2 separately confined applications that both use the
    user-tmp abstraction depend on being able to cooperatively share files
    with each other in /tmp or /var/tmp.
  * remove the following patches (features not appropriate for SRU):
    - 0002-add-chromium-browser.patch
    - 0003-local-includes.patch
    - 0004-ubuntu-abstractions-updates.patch
  * debian/rules (this makes it the same as what was shipped in 10.04 LTS
    release):
    - don't ship aa-update-browser and its man page (requires
      0004-ubuntu-abstractions-updates.patch)
    - don't ship apparmor.d/local/ (requires 0003-local-includes.patch)
    - don't use dh_apparmor (not in Ubuntu 10.04 LTS)
    - don't ship chromium profile
  * remove debian/profiles/chromium-browser
  * remove debian/aa-update-browser*
  * debian/apparmor-profiles.postinst: revert to that in lucid release
    (requires dh_apparmor and 0002-add-chromium-browser.patch)
  * remove debian/apparmor-profiles.postrm: doesn't make sense without
    0002-add-chromium-browser.patch
  * debian/control:
    - revert Build-Depends on debhelper (>= 5)
    - revert Standards-Version to 3.8.4
    - revert Vcs-Bzr
    - use Conflicts/Replaces version that was in Ubuntu 10.04 LTS
  * debian/patches/0011-lucid-compat-dbus.patch: move /var/lib/dbus/machine-id
    back into dbus, since profiles on 10.04 LTS expect it there
  * debian/patches/0012-lucid-compat-kde.patch: add kde4-config to kde
    abstraction, since the firefox profile on Ubuntu 10.04 LTS expects it to
    be there
