sysnet_read_config(gogoc_t) is duplicate since it is already called in
auth_use_nsswitch(gogoc_t)
allow radvd_t gogoc_var_run_t:file rw_file_perms; can be changed to:
allow radvd_t gogoc_var_run_t:file write_file_perms; since:
gogoc_read_pid_files(radvd_t) already allows radvd_t to read
gogoc_var_run_t files
Not sure but:
files_tmp_filetrans(gogoc_t, gogoc_tmp_t, { file dir }) can probably be
changed to:
files_tmp_filetrans(gogoc_t, gogoc_tmp_t, dir) since the type transition
probably is only needed for the dir (the file is probably created inside
this dir)
allow gogoc_t radvd_etc_t:file manage_file_perms; if this file gets
created by gogoc_t, then this probably needs a file type transition rule
as well, since the config file is located in /etc/ so without a type
transition rule the file would be created with type etc_t instead of
type radvd_etc_t
allow gogoc_t gogoc_tmp_t:file manage_file_perms; this is a duplicate
rule and can be removed
allow gogoc_t gogoc_log_t:file manage_file_perms insufficient, and may
be improved:
create_files_pattern(gogoc_t, gogoc_log_t, gogoc_log_t)
allow gogoc_t gogoc_log_t:file { append_file_perms read_file_perms
setattr_file_perms };
This will remove the write permission which gogoc_t shouldnt need ( log
files should be opened for append only)
gogoc_t probably needs to be able to create log file which means it
needs to be able to write/add directory entries to parent
dir /var/log/gogoc
allow gogoc_t gogoc_var_lib_t:file manage_file_perms;
allow gogoc_t gogoc_var_lib_t:dir rw_dir_perms;
allow gogoc_t gogoc_var_run_t:file manage_file_perms;
allow gogoc_t gogoc_var_run_t:dir rw_dir_perms;
allow gogoc_t gogoc_etc_t:file read_file_perms;
allow gogoc_t gogoc_etc_t:dir list_dir_perms;
These can be improved a bit by user patterns instead:
example:
manage_files_pattern(gogoc_t, gogpc_var_lib_t, gogoc_var_lib_t)
manage_files_pattern(gogoc_t, gogpc_var_run_t, gogoc_var_run_t)
read_files_pattern(gogoc_t, gogpc_etc_t, gogoc_etc_t)
This might shave off some unneeded permissions as well
type gogoc_etc_t;
files_config_file(gogoc_etc_t)
I would probably name this type "gogoc_conf_t" instead since
"gogoc_etc_t" refers to a path instead of a property of a file ( nitpick
but in light of consistent and self-documenting policy better to get
used to the best choices)
allow gogoc_t self:unix_dgram_socket create_socket_perms; Duplicate
rule: allowed included with: logging_send_syslog_msg(gogoc_t)
allow gogoc_t self:udp_socket create_socket_perms; duplicate rule:
already incuded with
auth_use_nsswitch(gogoc_t)
