Description Nivag 2013-08-21 00:45:04 UTC 
Description of problem:

trying to run:
http://localhost/cgi-bin/cachemgr.cgi
SELinux is preventing /var/www/cgi-bin/cachemgr.cgi from 'search' accesses on the directory /etc/squid.

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

If you believe that cachemgr.cgi should be allowed search access on the squid directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep cachemgr.cgi /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 4 Miroslav Grepl 2013-08-22 13:39:25 UTC 
# chcon -t httpd_squid_script_exec_t /var/www/cgi-bin/cachemgr.cgi

will fix it. What does

$ rpm -qf /var/www/cgi-bin/cachemgr.cgi
Comment 5 Nivag 2013-08-22 21:22:36 UTC 
# rpm -qf /var/www/cgi-bin/cachemgr.cgi
file /var/www/cgi-bin/cachemgr.cgi is not owned by any package

N.B.  I got the same answer before & after executing:
chcon -t httpd_squid_script_exec_t /var/www/cgi-bin/cachemgr.cgi
Comment 6 Miroslav Grepl 2013-08-27 14:07:25 UTC 
Is this your own CGI script?
Comment 7 Nivag 2013-08-27 21:06:20 UTC 
No - I assume cachemgr.cgi was installed by the Fedora Squid package, I have not even looked at it.
Comment 8 Miroslav Grepl 2013-08-29 07:46:36 UTC 
# rpm -qf /var/www/cgi-bin/cachemgr.cgi
file /var/www/cgi-bin/cachemgr.cgi is not owned by any package
Comment 9 Daniel Walsh 2013-08-29 12:52:28 UTC 
Looks like that file should be in /usr/lib64/squid/cachemgr.cgi
Comment 10 Daniel Walsh 2013-08-29 12:53:01 UTC 
But we should probably label in that location also, since that might be where the upstream package puts it.
Comment 11 Michal Luscon 2014-04-28 10:07:08 UTC 
I presume you manually copied cachemgr.cgi into your /var/www/cgi-bin/ or installed squid from different source. Fedora package installs cachemgr.cgi into /usr/lib64/squid and you can access it on http://localhost/Squid/cgi-bin/cachemgr.cgi with selinux in enforcing mode.

Feel free to reopen this bugzilla if I am wrong.
