Hello Dr., or anyone else affected, Accepted audit into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/audit/1:2.8.2-1ubuntu1.1 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-bionic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to audit in Ubuntu. https://bugs.launchpad.net/bugs/1848330 Title: Installing auditd sometimes fails in post-inst Status in audit package in Ubuntu: Fix Released Status in audit source package in Bionic: Fix Committed Status in audit package in Debian: New Bug description: [Impact] Sometimes, auditd will get stuck when starting up, causing systemd to kill it after a while since it (systemd) never got the start notification. Upstream troubleshooted this to be caused by calling a syslog() function inside a signal handler. [Test Case] There is no reliable test case to reproduce the bug, other than trying the fixed packages on an affected system where the hang occurs more frequently. Basically: sudo systemctl stop auditd sudo systemctl start auditd should work reliably. Do not run that in a tight loop, however, as that will trigger a it's-restarting-too-frequently failure. [Where problems could occur] - if auditd fails to start, then the first fallback is syslog, and if that is not picking up the audit messages, the last resort is the kernel buffer, which can fill up. In the case it fills up, audit logs will be lost. - it's possible to configure the audit system to panic() the machine if audit messages are lost or otherwise not able to be recorded (auditctl -f 2; default is 1 which is printk()) - the update restarts auditd as expected. Misconfiguration on very very busy systems could mean that audit logs would be lost during the brief moment the service is restarted. If that's the case, this update would just be one more way to trigger it, but not be the root cause of the problem - similarly, as is usual with updates that restart services, it's possible than an incorrect configuration for auditd is present, but was never loaded before. The restart will load the config, and will fail in such a case. - this update removes a logging statement that occurs during startup: ("dispatcher %d reaped", pid) It's unlikely, but possible, that some monitoring software could be looking for that message in the logs. It won't be there anymore after this update. [Other Info] The patch is committed upstream and part of the 2.8.5 release, which is present in Focal and later. The real fix for this bug is just dropping the audit_msg() call in the signal handler code. But the original reporter of the bug, who is also who came up with the fix (see https://bugzilla.redhat.com/show_bug.cgi?id=1587995#c4) stated that with the 3 changes in the patch the startup hang didn't happen to him anymore. Since this bug is difficult to reproduce elsewhere (either you have it, or you don't), I chose to keep the 3 changes instead of just the removal of the audit_msg() call. [Original Description] This happens sometimes when installing auditd on Ubuntu 18.04.2, most installations work successfully, though. Re-running the install also fixes the issue, but the failure breaks our automation. The log from the failure looks like this: # apt install auditd ... Setting up auditd (1:2.8.2-1ubuntu1) ...
