Description Milos Malik 2008-04-01 14:34:09 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; cs-CZ; rv:1.8.1.13) Gecko/20080325 Fedora/2.0.0.13-1.fc8 Firefox/2.0.0.13

Description of problem:
During processing of a configuration file logrotate doesn't check whether the included file isn't the same. It leads to segmentation fault.

During processing of a configuration file logrotate doesn't check whether the included directory isn't the same as the directory of that file. It leads to logrotate infinite loop.

Version-Release number of selected component (if applicable):
logrotate-3.7.1-8

How reproducible:
Always


Steps to Reproduce:
1. write "include /etc/logrotate.d/syslog" on the 1st line of /etc/logrotate.d/syslog file
2. /etc/cron.daily/logrotate


Actual Results:
/etc/cron.daily/logrotate: line 3:  8634 Segmentation fault      /usr/sbin/logrotate /etc/logrotate.conf


Expected Results:
Some message which warns you about recursive includes and skipping the file.

Additional info:

Comment 1 Tomas Smetana 2008-04-03 08:56:44 UTC
The segmentation fault seems to have the same cause as in the bug #440202. 
However the detection of recursive includes might be an useful feature.
