Description Tavis Ormandy 2015-08-07 18:06:11 EDT
Description of problem:
SELinux is preventing appLoader from 'open' accesses on the file /run/lock/LCK..ttyS0.

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

If you believe that appLoader should be allowed open access on the LCK..ttyS0 file 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 appLoader /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Lukas Vrabec 2015-08-22 13:47:55 EDT
Do you know, who own "/run/lock/LCK..ttyS0" ? 

Thank you.
Comment 2 Miroslav Grepl 2015-08-27 13:00:56 EDT
Have you ever run in permissive mode? The question is who creates this lock file.
Comment 3 Daniel Walsh 2015-09-15 08:45:25 EDT
Most likely an init script. Or something in the unit file?
Comment 4 Fedora End Of Life 2015-11-04 10:23:40 EST
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. 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bug reports from releases that are no longer maintained.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 '21'.

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 21 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 2015-12-02 09:51:11 EST
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 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no longer maintained, which means that it will not receive any further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

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