policy_module(apache,1.0.1) # # NOTES: # This policy will work with SUEXEC enabled as part of the Apache # configuration. However, the user CGI scripts will run under the # system_u:system_r:httpd_$1_script_t domain where $1 is the domain of the # of the creating user. # # The user CGI scripts must be labeled with the httpd_$1_script_exec_t # type, and the directory containing the scripts should also be labeled # with these types. This policy allows user_r role to perform that # relabeling. If it is desired that only sysadm_r should be able to relabel # the user CGI scripts, then relabel rule for user_r should be removed. # ######################################## # # Declarations # attribute httpdcontent;
