Public bug reported: The auditd daemon is not part of the default phone images. At the kernel level, the audit_enabled variable remains 0 until an auditd daemon registers itself. There is a bug in old kernels that causes AUDIT_USER_AVC messages to be ignored when audit_enabled is 0. I fixed the bug several years ago and marked the patch for the stable tree but the phone kernels (mako, at least) did not pull in the patch. The upstream commit id is:
0868a5e150bc4c47e7a003367cd755811eb41e0b What this means for our phone images is that any denial messages from the system D-Bus daemon are dropped instead of being properly routed to the syslog. This results in headaches for debugging app confinement denials. ** Affects: linux-flo (Ubuntu) Importance: Medium Assignee: Tyler Hicks (tyhicks) Status: In Progress ** Affects: linux-mako (Ubuntu) Importance: Medium Assignee: Tyler Hicks (tyhicks) Status: In Progress ** Affects: linux-manta (Ubuntu) Importance: Medium Assignee: Tyler Hicks (tyhicks) Status: In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1473584 Title: AUDIT_USER_AVC messages are not printk'ed when auditd is not running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-flo/+bug/1473584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
