Unfortunately that breaks if /var is a symlink (to /home/sys-var in my case) even if a correct alias rule is setup. I'll paste the details from #apparmor: [22:00] <cboltz> I get unexpected DENIED events in combination with aliases: [22:00] <cboltz> apparmor="DENIED" operation="mkdir" parent=1 profile="/usr/sbin/avahi-daemon" name="/home/sys-var/run/avahi-daemon/" pid=14842 comm="avahi-daemon" requested_mask="c" denied_mask="c" fsuid=0 ouid=0 [22:00] <cboltz> but I have in tunables/alias [22:01] <cboltz> alias /var/ -> /home/sys-var/, [22:01] <cboltz> and the profile for avahi-daemon allows write access to /var/run/avahi-daemon/ (original profile as in bzr) [22:01] <cboltz> is this a known or a new bug? [22:52] <sbeattie> cboltz: sorry, jjohansen and I are at the Ubuntu Developer Summit this week, so we're bouncing on and off irc. [22:53] <sbeattie> cboltz: not a known bug to me [22:54] <cboltz> then it must be a new one [22:56] <cboltz> I just found what causes it [22:57] <sbeattie> cboltz: oh? [22:57] <cboltz> /{,var/}run/avahi-daemon/ w, fails the alias replacement [22:57] <cboltz> /var/run/avahi-daemon/ w, works [23:00] <sbeattie> doh [23:01] <sbeattie> that's a result of aliases being more like a pre-processing step than a real semantic change. [23:02] <cboltz> looks like it should be a real semantic change *g* [23:03] <sbeattie> Feel free to raise the issue on the list or file a bug, though I'm not sure that it'd be an easy thing to address. [23:03] <cboltz> I'll send a mail [23:04] <sbeattie> cool, thanks! [23:04] <cboltz> just tell John that I found a bug again, and then enjoy the developer summit [23:04] <sbeattie> hehe [23:06] * sbeattie vanishes again To manage notifications about this bug go to: https://bugs.launchpad.net/apparmor/+bug/888077/+subscriptions -- AppArmor mailing list AppArmor@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/apparmor
