Oops, disregard the previous policy. With that graphing is still broken. Better one:
module munin-local 1.0;
require {
type munin_log_t;
type munin_etc_t;
type httpd_t;
type httpd_munin_script_t;
type tmp_t;
class process { siginh noatsecure rlimitinh };
class unix_stream_socket { write getattr shutdown read ioctl accept };
class dir { write read remove_name create add_name };
class file { write setattr create unlink open };
}
#============= httpd_munin_script_t ==============
allow httpd_munin_script_t httpd_t:unix_stream_socket { write getattr shutdown read ioctl accept };
allow httpd_munin_script_t munin_etc_t:dir read;
allow httpd_munin_script_t munin_log_t:dir { write add_name };
allow httpd_munin_script_t munin_log_t:file create;
allow httpd_munin_script_t tmp_t:dir { write remove_name create add_name };
allow httpd_munin_script_t tmp_t:file { write create unlink open setattr };
#============= httpd_t ==============
allow httpd_t httpd_munin_script_t:process { siginh rlimitinh noatsecure };
Please attach the original AVC's. These can be passed along and isolated better than the policy you posted above. Example: sudo ausearch -m avc -ts recent > /tmp/recent-avc.txt Hi,
To be able to do the same thing (namely html pages and graphs being created by CGIs), I needed the following:
module munin-local 1.0;
require {
type tmp_t;
type httpd_munin_script_t;
type munin_etc_t;
class file { write create unlink open setattr };
class dir { write remove_name create read add_name };
}
#============= httpd_munin_script_t ==============
allow httpd_munin_script_t munin_etc_t:dir read;
allow httpd_munin_script_t tmp_t:dir { write remove_name create add_name };
allow httpd_munin_script_t tmp_t:file { write create unlink open setattr };
If you have more questions, let me know.
Please attach the original AVC's. These can be passed along and isolated better than the policy you posted above. Example: sudo ausearch -m avc -ts recent > /tmp/recent-avc.txt Also, please update to munin-2.0.21-1.fc20.noarch Created attachment 915914 [details]
