Subject: [refpolicy] [PATCH 1/1] Allow capabilities for syslog-ng
Date: Mon, 21 Oct 2013 20:52:05 +0200	[thread overview]
Message-ID: <20131021185205.GA21893@siphos.be> (raw)

The syslog-ng logger has (build-optional) support for capabilities. If
capabilities support is enabled, running it without setcap/getcap
permissions gives the following upon start:

 * Starting syslog-ng ...
syslog-ng: Error setting capabilities, capability management disabled;
error='Permission denied' [ ok ]

Granting only setcap (initial AVC seen) does not fully help either:

 * Starting syslog-ng ...
 Error managing capability set, cap_set_proc returned an error;

With setcap and getcap enabled, syslog-ng starts and functions fine.
