FYI: the fixes will also need a minor backport change due to [1], but cmsg isn't touched in the new changes so no backport of [1] itself is needed (which would in turn change more than we want and affect other subsystems)
[1]: https://github.com/systemd/systemd/commit/371d72e05b7e2c2b7850cb04d8d4c18be1e60421 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1875708 Title: Truncated messages in journald since systemd v244 Status in libvirt package in Ubuntu: Invalid Status in systemd package in Ubuntu: New Bug description: [Impact] * since 09d0b46a "journal: refresh cached credentials of stdout streams" in ~244 output may be trincated. * Upstream has a fix in https://github.com/systemd/systemd/pull/15685 * Backporting the fix will avoid truncation of log output to journald [Test Case] * This could happen in any case, but is more likely when a program that has output going to journald is spawning short-lived sub-programs often. Therefore the test emphasizes on that: - Use a test service like /etc/systemd/system/test.service: [Unit] Description=Test Truncate After=network.target [Service] ExecStart=/usr/lib/test.sh long-test-for-start ExecStop=/usr/lib/test.sh long-test-for-stop Type=oneshot RemainAfterExit=yes StandardOutput=journal+console TimeoutStopSec=0 [Install] WantedBy=multi-user.target - And a test script like /usr/lib/test.sh: #!/bin/sh gettext "This will" echo gettext "usually fail" echo gettext "and be truncated" echo Start/Stopping that service without the fix will look like: Apr 30 18:56:40 f systemd[1]: Stopping Test Truncate... Apr 30 18:56:40 f test.sh[1165]: T Apr 30 18:56:40 f test.sh[1167]: T Apr 30 18:56:40 f test.sh[1167]: sually fai Apr 30 18:56:40 f test.sh[1165]: s Apr 30 18:56:40 f test.sh[1168]: s Apr 30 18:56:40 f test.sh[1168]: nd be truncate Apr 30 18:56:40 f test.sh[1165]: n Apr 30 18:56:40 f systemd[1]: test.service: Succeeded. Apr 30 18:56:40 f systemd[1]: Stopped Test Truncate. [Regression Potential] * The patches are rather small, but there might be a slightly increased memory consumption of journald for output buffers. * Issues (if any and I couldn't find any so far) should be only to journald output handling. Systemd is huge, this at least narrows down the potential places of a regression a lot.
