Description of problem:
SELinux is preventing /usr/sbin/httpd from 'write' accesses on the directory /etc/pki/ca-trust/source.

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

If vous pensez que httpd devrait être autorisé à accéder write sur source directory par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
autoriser cet accès pour le moment en exécutant :
# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

*** Bug 988209 has been marked as a duplicate of this bug. ***
Comment 2 Daniel Walsh 2013-07-25 10:12:48 EDT
Does not seem like a good idea to allow the apache server to write to certificate directories.  Is the /etc/pki/ca-trust/source something different?
Comment 3 Miroslav Grepl 2013-07-26 04:50:31 EDT
Did it work in enforcing mode?
Comment 4 Nicolas Mailhot 2013-07-26 05:50:43 EDT
rawhide does not seem to boot in enforcing mode right now (lots of /dev problems) the avc was generated in permissive mode

It may be linked to this (new) cron warning


p11-kit: the CKA_X_CRITICAL attribute is not valid for the object
p11-kit: couldn't load file into objects:
Comment 5 Nicolas Mailhot 2013-07-26 05:51:52 EDT
(should really cc the certwatch and pk11-kit maintainers on this bug, but the package names elude me and I have no Fedora system on-hand to check)
Comment 6 Daniel Walsh 2013-07-26 13:38:18 EDT
Actually this is just an access check.
Comment 7 Frank Murphy 2013-07-27 05:53:39 EDT
Getting this in enforcing mode.
same */certwatch warnings.
Comment 8 Frank Murphy 2013-07-27 05:56:06 EDT

PS; with the certutil from # 988209
Comment 9 Stef Walter 2013-07-30 06:05:21 EDT
(In reply to Daniel Walsh from comment #6)
> Actually this is just an access check.

Yes, this is an access() check within the p11-kit trust module, so it can report the correct flags about whether the PKCS#11 token is read-only or not. If it can be masked out, that makes sense.

Comment 14 Fedora End Of Life 2015-05-29 05:13:12 EDT
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. 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bug reports from releases that are no longer maintained.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 '20'.

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 20 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 15 Fedora End Of Life 2015-06-29 21:32:12 EDT
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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.
