Description fedbugs 2010-10-02 00:46:53 UTC

Description of problem:

Smokeping is not displaying the target graphs when SELinux is in "Enforcing" mode. There is no problem when SELinux is set to "Permissive".

Version-Release number of selected component (if applicable):

smokeping-2.4.2-10.fc12.noarch (this could be a problem in itself as there is no fc13 build of this package available)

How reproducible:

Constantly.

Steps to Reproduce:
1. Enable httpd & smokeping daemons
2. Load "http://localhost/smokeping/sm.cgi" in browser (Firefox 3.6.10 in this instance)
3. Click on one of the smokeping targets under 'charts' in the menu sidebar
4. Error messages will be displayed in '/var/log/messages' & '/var/log/audit/audit.log'
  
Actual results:

No target charts (and associated information) displayed.

Expected results:

Target chart and associated information.

Comment 1 Daniel Walsh 2010-10-03 11:24:35 UTC

Miroslav add

	smokeping_read_lib_files(httpd_t)

and

	manage_dirs_pattern(httpd_smokeping_cgi_script_t, smokeping_var_lib_t, smokeping_var_lib_t)

Comment 2 Dominick Grift 2010-10-03 15:38:39 UTC

Why would httpd_t need to read smokeping_var_lib_t files. Is this some inheritance issue?

Comment 3 Miroslav Grepl 2010-10-04 11:58:26 UTC

Looks like httpd reads /var/lib/smokeping/images/*.png files.

Comment 4 Dominick Grift 2010-10-04 16:12:45 UTC

But why httpd_t and not httpd_smokeping_cgi_script_t?

Comment 5 Miroslav Grepl 2010-10-05 14:58:55 UTC

Fixed in selinux-policy-3.7.19-64.fc13
