AppArmor profiles need updates for /var/run → /run and /var/lock → /run/lock and /dev/shm → /run/shm

[Micah Gersten]

Figured I'd file a tracking bug for this. The symlink exists from /var/run to /run, but I'm guessing the profiles don't like this. The main problems I've seen so far are cups and dhclient (which I think are both profiles in their respective packages).

sbin.dhclient and usr.sbin.cupsd profiles also refer to /var/run/, adding tasks for these as well.

[Jamie Strandboge (jdstrand)]

*sigh* This requires a lot of changes.

Seems Jamie already has an update for gdm-guest-session

[Launchpad Janitor (janitor)]

This bug was fixed in the package cups - 1.4.7-1

---------------
cups (1.4.7-1) unstable; urgency=low

  * New upstream version.

  [ Till Kamppeter ]
  * debian/patches/ubuntu-upstart.dpatch: Updated the patch to add support
    to the new device enumeration functionality of udev-configure-printer.
    This way we do not need to retrigger the printers. Retriggering is only
    needed if udev rules change. A fallback to the old bahavior is provided
    so that this CUPS package continues to work with older versions of
    udev-configure-printer.

  [ Martin Pitt ]
  * Update patches for new upstream release.
  * Drop fix-broken-ipv6-uris.patch, applied upstream.
  * debian/local/apparmor-profile: /var/run → /run transition. (LP: #810270)
  * Drop debian/patches/ubuntu-upstart.dpatch and move the upstart script to
    debian/local/cups.upstart. In debian/rules, copy it to debian/, and remove
    that again during clean. This is a slightly easier workaround for a
    nonexisting "dh_installinit --sysvinit-only" option than the previous
    creation of the upstart file with an ubuntu specific dpatch.
  * debian/patches/, debian/rules, debian/control, debian/source/format: Move
    to source format "3.0 (quilt)" and convert our dpatches to quilt patches.
    Drop dpatch build dependency.
  * Move Ubuntu specific patches to debian/patches/ubuntu. In debian/rules,
    apply them when building on Ubuntu. Add "patch" build dependency.

[Jürgen (jurgen-depicker)]

I'm affraid it's not fixed yet for mysql Ver 14.14 Distrib 5.1.58, for debian-linux-gnu (x86_64). http://penguindroppings.wordpress.com/2009/07/07/should-i-disable-apparmor/ was my help to temporary disable the profile for mysql to get things working again:
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.mysqld
sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/usr.sbin.mysqld
sudo service mysql start
mysql start/running, process 3024

Before doing this, I got this from dmesg:
type=1400 audit(1319135491.751:5641): apparmor="STATUS" operation="profile_replace" name="/usr/sbin/mysqld" pid=2704 comm="apparmor_parser"
[84848.322283] type=1400 audit(1319135491.915:5642): apparmor="DENIED" operation="mknod" parent=1 profile="/usr/sbin/mysqld" name="/run/mysqld/mysqld.sock" pid=2708 comm="mysqld" requested_mask="c" denied_mask="c" fsuid=116 ouid=116
[84853.637467] init: mysql main process (2708) terminated with status 1
[84853.637505] init: mysql main process ended, respawning

[Jamie Strandboge (jdstrand)]

Jurgen, this sounds like you may have not accepted the changes to /etc/apparmor.d/usr.sbin.mysqld on upgrade. Please look in /etc/apparmor.d/ for *dpkg* files and merge the changes. If this is not the case, please file a new bug with 'ubuntu-bug mysql-5.1'. Thanks

[Jürgen (jurgen-depicker)]

I'm sorry I forgot to mention that this is on a blank new install. Unfortunately, so I'll give it a try and file that bug!

[cideous (mr-nightmare)]

Continously I get errors of the form:

[ 4961.366862] type=1400 audit(1329587229.044:159): apparmor="DENIED" operation="mknod" parent=1049 profile="/sbin/dhclient" name="/var/lib/dhcp/dhclient-8740e579-0e00-4d28-acc6-c9998a25e262-eth0.lease" pid=1589 comm="dhclient" requested_mask="c" denied_mask="c" fsuid=0 ouid=0

Is this because this bug is still unsolved for dhclient, or is this because of the way setup my filesystem. Note that I made /var a symlink to a different partition. My root filesystem is an SSD and I followed the recommendation not to have var on the SSD. So is this just because I'm using a symlink here and I shouldn't have used it here?

[Kees Cook (kees)]

If filesystem paths have been relocated, please use /etc/apparmor.d/tunables/alias to handle replacements.
