:SELinux is preventing /usr/libexec/colord from using the 'sys_admin' capabilities.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that colord should have the sys_admin capability by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep colord /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-08-15 11:41:14 UTC
I added a dontaudit to selinux-policy-3.10.0-19.fc16  Since it seems to be working for you and I don't want to give this powerfull capability to colord.

Comment 2 Mads Kiilerich 2011-08-15 13:36:11 UTC
I'm not 100% sure this system really was enforcing. I think it was a livecd that was started with enforcing=0 and I'm also not sure that the system really worked correctly if this was blocked. I just know that I got this and it seemed to be a genuine problem not caused by other strange things that might have been going on.

Anyway: It seems reasonable that colord shouldn't use sys_admin privileges, so isn't this a colord bug?

Comment 3 Daniel Walsh 2011-08-16 11:43:39 UTC
Well the alert says that it was in enforcing mode.

The avc that was generated for colord_t on the OPEN syscall was successful. success=yes.

Not sure what colord people can tell us, but I will reassign.

Was there anything special about the filesystem(s) on your machine?

Comment 4 Fedora End Of Life 2013-01-17 01:55:49 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 

Comment 5 Fedora End Of Life 2013-02-14 02:56:26 UTC
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
