I was able to narrow down this apparmor_parser error to shiftfs: AppArmor parser error for /etc/apparmor.d/sbin.dhclient in /etc/apparmor.d/tunables/home at line 25: Could not process include directory '/etc/apparmor.d/tunables/home.d' in 'tunables/home.d'
The problem stems from shiftfs not handling this sequence: getdents() lseek() to reset the f_pos to 0 getdents() I'm attaching a test case for this issue, called dir-seek.c. When ran on a non-shiftfs filesystem, you'll see something like this: $ ./dir-seek PASS: orig_count (29) == new_count (29) When you run the test case on shiftfs, you'll see something like this: $ ./dir-seek FAIL: orig_count (29) != new_count (0) The f_pos of the directory file is not properly tracked/reset on shiftfs. ** Attachment added: "dir-seek.c" https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1824812/+attachment/5256075/+files/dir-seek.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824812 Title: apparmor does not start in Disco LXD containers To manage notifications about this bug go to: https://bugs.launchpad.net/apparmor/+bug/1824812/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
