[Bug 131976] Re: apparmor doesn't work on stacked file system (livecd) -- DHCP/cups/others fail to start
IF the problem is the stacked file system, then why am I able to, after booting, do: sudo /etc/init.d/apparmor start on my persistent 9.10 Live CD and have no errors? Is it possible that this 'bug' with the stacked file system is just a problem caused by the Ubuntu initrd.lz trying to load apparmor profiles before the casper script has had a chance to fully create the stacked file system? (please see prior post #44 that addresses the sequence of script events during the Live CD boot process) I am just wondering if the problem is with the Ubuntu customization of the 'init' and 'casper' scripts within the Ubuntu initrd.lz, and not really an upstream problem at all. -- apparmor doesn't work on stacked file system (livecd) -- DHCP/cups/others fail to start https://bugs.launchpad.net/bugs/131976 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 131976] Re: apparmor doesn't work on stacked file system (livecd) -- DHCP/cups/others fail to start
If you look at sudo aa-status, I would expect that DHCP and CUPS are not actually being confined by AppArmor, so there aren't errors. If you restart the network or CUPS after starting AppArmor in the LiveCD, I would expect those services to start failing. If that's _not_ the case, then this should be examined further. -- apparmor doesn't work on stacked file system (livecd) -- DHCP/cups/others fail to start https://bugs.launchpad.net/bugs/131976 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 131976] Re: apparmor doesn't work on stacked file system (livecd) -- DHCP/cups/others fail to start
Is it possible this problem is caused by a sequencing problem with the Live CD scripts? I run the Karmic LiveCD in persistent mode on a hard disk drive. Once I am logged in to Ubuntu, I can run 'sudo /etc/init.d/apparmor start' and see no errors in the terminal nor the log files. The kernel log shows all the aparmor profiles are loaded. Everything works normally. In looking at the Karmic initrd.lz content, it appears that the '/init' script calls '/scripts/init-bottom/apparmor', which then tests for the existence of a file called '/scripts/casper-bottom/42disable-apparmor'. The latter file will be found when booting with the Live CD software, and finding that file will cause '/scripts/init-bottom/apparmor' to early exit instead of loading the apparmor profiles. The apparent reason for the early exit, in lieu of loading the profiles, is the assumed failure of apparmor to deal deal with the union file system created by the live CD software. BUT, when the early exit is taken, the '/scripts/casper' script that sets up the union files system has NOT YET RUN, as far as I can see, so of course apparmor would have a problem finding and loading profiles? Is it possible that simply changing the apparmor profile load process to follow the creation of the union file system, would allow apparmor to execute properly? It seems like an odd coincidence that lots of software EXCEPT apparmor appears to run flawlessly on the 'stacked' file system, and that apparmor is happy to load profiles after booting the Live CD? -- apparmor doesn't work on stacked file system (livecd) -- DHCP/cups/others fail to start https://bugs.launchpad.net/bugs/131976 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Nikolaus upstream does watch here and track bugs filed in launchpad. This particular issue arise due to the LSM not providing AppArmor sufficient information about access on stacked file systems.

Turning apparmor off on the LiveCD is ignoring the underlying problem that apparmor doesn't work on stacked file systems.
