# This policy module provides support for mod_fcgid using the httpd system script domain.

# It provides "allow" rules that will overlap to varying degrees with selinux-policy
|
|
|
0ce23f |
# packages for Fedora 5 onwards, and is a stepping stone to the merged policy included
|
|
|
0ce23f |
# as updates for selinux-policy in Fedora 8, 9, and 10.
|
|
|
0ce23f |
#

# Rules existing in selinux-policy 2.3.7 (FC5) have been stripped from this policy

# Previous versions of this policy module used a separate domain, httpd_fastcgi_script_t,
|
|
|
0ce23f |
# which is now an alias for httpd_sys_script_t.
