Description larchunix 2013-11-21 11:34:01 UTC
The postinstall scriptlet try to apply the context httpd_sys_script_rw_t on files matching the patterns "/etc/glpi(/.*)?" and "/var/lib/glpi(/.*)?".

However, it seems this type does not exist :

/usr/sbin/semanage: Type httpd_sys_script_rw_t is invalid, must be a file or device type

The command seinfo -t does not list this type.

As a result, with selinux in enforcing mode, Step 0 of GLPI configuration fails.

Additional info:

On my installation, I fixed the issue using the httpd_sys_rw_content_t type instead of httpd_sys_script_rw_t (maybe a better context exists and should be used in this situation).

Damn... good catch.
Thanks for the report.

Comment 3 larchunix 2013-11-21 14:02:57 UTC
The fix should be merged on Fedora branches too as the issue is also present at least in Fedora 19 (Maybe you already planned to do it).

Comment 4 Remi Collet 2013-11-21 14:05:54 UTC
For fedora, I'm waiting for feedback on bug #1032025 as having context defined in main policy will avoid such error in the future (don't remember when the context was renamed and how I can have miss it)

Comment 5 Remi Collet 2013-11-21 14:06:51 UTC
I mean Bug #1033025

Comment 6 larchunix 2013-11-21 19:39:53 UTC
There is already a context present in the main policy for GLPI :

/var/lib/glpi/files(/.*)?  all files  system_u:object_r:cron_var_lib_t:s0

This pattern is more specific than the pattern /var/lib/glpi(/.*)?.

Currently, as we use the semanage command to add the rule on /var/lib/glpi(/.*)? this rule has priority.

IIRC, if we do not use semanage command, the more specific rule has priority, i.e : the type cron_var_lib_t will be applied on files under the /var/lib/glpi/files directory.

If my reasoning is correct, it means that only cron will have access to the content of the /var/lib/glpi/files directory and httpd will not have access to this directory anymore.

According to the content of this directory, it seems that http should have access to this directory, so I think the existing rule is problematic here.

Comment 7 Remi Collet 2013-11-22 08:27:46 UTC
I don't know where the policy on /var/lib/glpi/file comes from...

I think this can be drop.

I run some tests on RHEL-6
 ll -aZ /var/lib/glpi/files/_cron/
drwxr-x---. apache root   system_u:object_r:httpd_sys_rw_content_t:s0 .
drwxr-x---. apache root   system_u:object_r:httpd_sys_rw_content_t:s0 ..
-rw-r--r--. apache apache unconfined_u:object_r:httpd_sys_rw_content_t:s0 test-20131122-092017
-rw-r--r--. apache apache system_u:object_r:httpd_sys_rw_content_t:s0 test-20131122-092201


The test-20131122-092017 file was created from an action triggered from the web UI.
The test-20131122-092201 file was created from a cron action.
