Impact scenarios : - System could eventually run out of disk space on a separate partition if mounted in "/var" or specifically "/var/log" or even worst if "/var/log" is on the same partition as "/" it could create even more damage if by any chance the partition is running out of free space. - System keep updating the same files over and over, creating large size logfiles. - ... [Test Case] - Install logrotate - Run "/etc/cron.daily/logrotate" ## The first logrotate run will generate the statefile "var/lib/logrotate/status" - Modify "/var/lib/logrotate/status" by removing the first line in order to corrupt the file - Re-run "/etc/cron.daily/logrotate" and one will get the following error : "error: bad top line in state file /var/lib/logrotate/status" every time you run logrotate Unless you remove the statefile and start again or fix the corruption by hand. * Additionally, I will run the /path_to_source/test/test script as a dogfooding that does ~72 tests. [Regression Potential] * Risk of potential regression is low, and IMHO couldn't be worst than the actual situation where logrotate simply doesn't recover from a corrupt statefile. * The current patch does recover (after verification) and has been through some upstream CI validation, community feedbacks, et al. * Additionally, I will run the /path_to_source/test/test script as a dogfooding that does ~72 tests.
