Updated logrotate packages that fix several bugs and add two enhancements are now available for Red Hat Enterprise Linux 6.
The logrotate utility simplifies the administration of multiple log files, allowing the automatic rotation, compression, removal, and mailing of log files.
- When the logrotate utility attempted to write its status file while insufficient disk space was available, logrotate wrote only part of the status file and stopped. When the disk space became free again, and log rotate attempted to read its records, logrotate terminated unexpectedly. This bug has been fixed, and logrotate no longer crashes in the aforementioned scenario.
- Previously, the daily cronjob of logrotate redirected all error messages to the /dev/null device file, thus suppressing all the relevant information for troubleshooting. With this update, all error messages containing detailed error reports are mailed to the root user. In addition, the /etc/cron.daily/logrotate file has been marked as a configuration file in RPM.
- Previously, the /etc/cron.daily/logrotate file had incorrect permissions set. This update changes the permissions to 0700, and /etc/cron.daily/logrotate now conforms to Red Hat security policy GEN003080.
- The logrotate utility incorrectly deleted data files alphabetically instead of based on their age when the when the "-%d-%m-%Y" date format was used. This update sorts files returned by the glob() function according to the date extension. As a result, when the aforementioned date format is used, the oldest log is now removed as expected.
Users of logrotate are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
