6 portmap_selinux - Security Enhanced Linux Policy for the portmap pro‐
7 cesses
8
10 Security-Enhanced Linux secures the portmap processes via flexible
11 mandatory access control.
12 The portmap processes execute with the portmap_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep portmap_t
20
24 The portmap_t SELinux type can be entered via the portmap_exec_t file
25 type.
26 The default entrypoint paths for the portmap_t domain are the follow‐
28 ing:
29 /sbin/portmap, /usr/sbin/portmap
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 portmap policy is very flexible allowing users to setup their portmap
40 processes in as secure a method as possible.
41 The following process types are defined for portmap:
43 portmap_t, portmap_helper_t
45 Note: semanage permissive -a portmap_t can be used to make the process
47 type portmap_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. portmap
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run portmap with the tightest access possi‐
56 ble.

171 SELinux defines port types to represent TCP and UDP ports.
172 You can see the types associated with a port by using the following
174 command:
175 semanage port -l
177 Policy governs the access confined processes have to these ports.
180 SELinux portmap policy is very flexible allowing users to setup their
181 portmap processes in as secure a method as possible.
182 The following port types are defined for portmap:
184 portmap_port_t
187 Default Defined Ports:
191 tcp 111
192 udp 111
193
195 The SELinux process type portmap_t can manage files labeled with the
196 following file types. The paths listed are the default paths for these
197 file types. Note the processes UID still need to have DAC permissions.
198 cluster_conf_t

244 SELinux requires files to have an extended attribute to define the file
245 type.
246 You can see the context of a file using the -Z option to ls
248 Policy governs the access confined processes have to these files.
250 SELinux portmap policy is very flexible allowing users to setup their
251 portmap processes in as secure a method as possible.
252 STANDARD FILE CONTEXT
254 SELinux defines the file context types for the portmap, if you wanted
256 to store files with these types in a diffent paths, you need to execute
257 the semanage command to sepecify alternate labeling and then use
258 restorecon to put the labels on disk.
259 semanage fcontext -a -t portmap_var_run_t '/srv/myportmap_con‐
261 tent(/.*)?'
262 restorecon -R -v /srv/myportmap_content
263 Note: SELinux often uses regular expressions to specify labels that
265 match multiple files.
266 The following file types are defined for portmap:
268 portmap_exec_t
272 - Set files with the portmap_exec_t type, if you want to transition an
274 executable to the portmap_t domain.
275 Paths:
278 /sbin/portmap, /usr/sbin/portmap
279 portmap_helper_exec_t
282 - Set files with the portmap_helper_exec_t type, if you want to transi‐
284 tion an executable to the portmap_helper_t domain.
285 Paths:
288 /sbin/pmap_set, /sbin/pmap_dump, /usr/sbin/pmap_set,
289 /usr/sbin/pmap_dump
290 portmap_initrc_exec_t
293 - Set files with the portmap_initrc_exec_t type, if you want to transi‐
295 tion an executable to the portmap_initrc_t domain.
296 portmap_tmp_t
300 - Set files with the portmap_tmp_t type, if you want to store portmap
302 temporary files in the /tmp directories.
303 portmap_var_run_t
307 - Set files with the portmap_var_run_t type, if you want to store the
309 portmap files under the /run or /var/run directory.
310 Paths:
313 /var/run/portmap_mapping, /var/run/portmap.upgrade-state
314 Note: File context can be temporarily modified with the chcon command.
317 If you want to permanently change the file context you need to use the
318 semanage fcontext command. This will modify the SELinux labeling data‐
319 base. You will need to use restorecon to apply the labels.
320
323 semanage fcontext can also be used to manipulate default file context
324 mappings.
325 semanage permissive can also be used to manipulate whether or not a
327 process type is permissive.
328 semanage module can also be used to enable/disable/install/remove pol‐
330 icy modules.
331 semanage port can also be used to manipulate the port definitions
333 semanage boolean can also be used to manipulate the booleans
335 system-config-selinux is a GUI tool available to customize SELinux pol‐
338 icy settings.
