Description Damon Hill 2016-01-03 18:52:14 UTC
Description of problem:
SELinux is preventing plugin-config from 'read' accesses on the blk_file /dev/dm-3.

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

If cree que de manera predeterminada, plugin-config debería permitir acceso read sobre  dm-3 blk_file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep plugin-config /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2016-01-04 13:29:19 UTC
This seems like a fairly dangerous access to allow.  Why would a mozilla plugin want to read a physical device?

Comment 2 Lukas Vrabec 2016-01-04 16:29:04 UTC
What kind of plugin did you use?

Comment 3 Fedora Admin XMLRPC Client 2016-09-27 15:00:24 UTC
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Comment 4 Fedora End Of Life 2016-11-24 14:40:49 UTC
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. 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bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora  'version'
of '23'.

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.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 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  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

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.

Comment 5 Fedora End Of Life 2016-12-20 17:34:40 UTC
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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no longer maintained, which means that it will not receive any further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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

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