[lxc-devel] LXC and Ubuntu 13.04

[Andre Nathan]

Hello

I've found the following issue running lxc-start on Ubuntu 13.04:

   lxc-start: Read-only file system - failed to change apparmor profile 
to unconfined

This happens despite "lxc.aa_profile = unconfined" being set in the 
container configuration. What happened was that aa_am_unconfined() was 
returning false, and investigating why I found that the string returned 
by aa_get_profile() was "unconfined\n/tty1" instead of simply "unconfined".

So adding this bit of code at the end of aa_get_profile() fixed the 
issue for me:

     space = index(buf, '\n');
     if (space)
         *space = '\0';

Has anyone seen this before? I'm not sure if this is a kernel bug (since 
the profile is being read from /proc) or an lxc bug... I'm using kernel 
3.8.0-27-generic and lxc 0.9.0-0ubuntu3.4.

There's a second issue: if I add an IPv6 address to the configuration, as in

   lxc.network.ipv6 = 2001:db8:fedc:abcd::2/80

it used to work on 12.04 but on 13.04 I get the following error:

   lxc-start 1377083732.942 ERROR    lxc_confile - No such file or 
directory - invalid ipv6 address: 2001:db8:fedc:abcd::2/80

Is this known?

Thanks
Andre
