Description Paulo Anes 2011-10-21 12:44:55 UTC
Logwatch is trying to read  /var/log/varnish and doesn't have selinux permission to do so.
Or logwatch should be fixed to don't try to read this log or selinux policy should be fixed.


SELinux is preventing /usr/bin/perl from 'read' accesses on the directory /var/log/varnish.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that perl should be allowed read access on the varnish directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep logwatch /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-10-21 13:49:38 UTC
varnishlog_log_t needs to use this interface.

logging_log_file(varnishlog_log_t)
