https://bugzilla.redhat.com/show_bug.cgi?id=2372533 Bug ID: 2372533 Summary: Use `systemctl kill` in logrotate postrotate script Product: Fedora Version: 42 OS: Linux Status: NEW Component: sssd Severity: low Assignee: sssd-maintainers(a)lists.fedoraproject.org Reporter: marcosfrm(a)gmail.com QA Contact: extras-qa(a)fedoraproject.org CC: abokovoy(a)redhat.com, atikhono(a)redhat.com, lslebodn(a)redhat.com, pbrezina(a)redhat.com, sbose(a)redhat.com, ssorce(a)redhat.com, sssd-maintainers(a)lists.fedoraproject.org Target Milestone: --- Classification: Fedora `systemctl kill` leverages systemd's knowledge of the daemon's main PID, eliminating the need to rely on PID files or external tools like `killall` or `pkill`. This ensures precise signal sending to the intended process, reducing the risk of errors in process identification. Additionally, using `systemctl kill` logs the signal sending in the service's journal, providing a record of actions taken. Requires selinux-policy-41.43 or higher (see https://bugzilla.redhat.com/show_bug.cgi?id=2369644) available as an update for F41, F42, and Rawhide. https://bodhi.fedoraproject.org/updates/FEDORA-2025-eb98eb9e24 (F41 -- will go to stable in a few days) https://bodhi.fedoraproject.org/updates/FEDORA-2025-f9f097f491 (F42 -- stable) https://bodhi.fedoraproject.org/updates/FEDORA-2025-3db4c0ec1c (Rawhide) The logrotate configuration snippet: # cat /etc/logrotate.d/sssd /var/log/sssd/*.log { weekly missingok notifempty sharedscripts rotate 2 compress delaycompress su sssd sssd postrotate /bin/kill -HUP `cat /run/sssd/sssd.pid 2>/dev/null` 2> /dev/null || true /bin/pkill -HUP sssd_kcm 2> /dev/null || true endscript } In the postrotate script, kill and pkill can be replaced by: /usr/bin/systemctl kill --signal=HUP --kill-whom=main sssd.service sssd-kcm.service 2>/dev/null || true Because: # systemctl show -P MainPID sssd.service 1225 # cat /run/sssd/sssd.pid 1225 # systemctl show -P MainPID sssd-kcm.service 1447 # pgrep sssd_kcm 1447 Reproducible: Always Additional Information: sssd-common-2.11.0-1.fc42.x86_64 -- You are receiving this mail because: You are on the CC list for the bug.
