Every now and then, a new rule needs to be added. In this particular case, the usage of the imjournal[1] module is being blocked by apparmor. Specifically, these accesses are being denied: apparmor="DENIED" operation="open" class="file" profile="rsyslogd" name="/run/log/journal/" pid=3351 comm="in:imjournal" requested_mask="r" denied_mask="r" fsuid=102 ouid=0 apparmor="DENIED" operation="open" class="file" profile="rsyslogd" name="/etc/machine-id" pid=3351 comm="in:imjournal" requested_mask="r" denied_mask="r" fsuid=102 ouid=0 This prevents the imjournal module from being used. 1. https://www.rsyslog.com/doc/configuration/modules/imjournal.html [ Test Plan ] - Deploy the ubuntu release under verification in a VM - enable the imjournal module by creating a config file for it (the whole command in one line): echo 'module(load="imjournal" fileCreateMode="0666" PersistStateInterval="999" StateFile="/var/spool/rsyslog/journal_state")' | sudo tee /etc/rsyslog.d/10-imjournal.conf - in another terminal, run this dmesg command: sudo dmesg -wT | grep apparmor | grep rsyslog - in yet another terminal, tail the logs: tail -f /var/log/syslog | grep rsyslogd - restart rsyslog: sudo systemctl restart rsyslog - with the affected version of rsyslog installed, you will see the apparmor DENIED messages in the dmesg terminal, and error messages about "imjournal" in the syslog logs - with the package from proposed, there should be no apparmor DENIED messages, and no imjournal errors [ Where problems could occur ] The extra apparmor rules we are adding allow reading of the systemd journal, and the /etc/machine-id file. There are no extra rules allowing writing, but we are allowing rsyslog to have access to more logs. But that is its purpose, after all. Specifically about the imjournal module, without this change, it is not working already. [ Other Info ] Other apparmor rules are being added to rsyslog via this upload, closing other bugs: - LP: #2056768 for noble only - LP: #2061726 for noble, oracular, and plucky IMPORTANT: this upload can only be accepted after gzip from https://bugs.launchpad.net/ubuntu/+source/gzip/+bug/2083700 is also accepted and published, otherwise rsyslog will FTBFS on s390x.
