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
13 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
17 For example:
18
19 ps -eZ | grep portmap_t
20
21
22
24 The portmap_t SELinux type can be entered via the portmap_exec_t file
25 type.
26
27 The default entrypoint paths for the portmap_t domain are the follow‐
28 ing:
29
30 /sbin/portmap, /usr/sbin/portmap
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 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
42 The following process types are defined for portmap:
43
44 portmap_t, portmap_helper_t
45
46 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
51
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.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 SELinux defines port types to represent TCP and UDP ports.
69
70 You can see the types associated with a port by using the following
71 command:
72
73 semanage port -l
74
75
76 Policy governs the access confined processes have to these ports.
77 SELinux portmap policy is very flexible allowing users to setup their
78 portmap processes in as secure a method as possible.
79
80 The following port types are defined for portmap:
81
82
83 portmap_port_t
84
85
86
87 Default Defined Ports:
88 tcp 111
89 udp 111
90
92 The SELinux process type portmap_t can manage files labeled with the
93 following file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.

156 SELinux requires files to have an extended attribute to define the file
157 type.
158
159 You can see the context of a file using the -Z option to ls
160
161 Policy governs the access confined processes have to these files.
162 SELinux portmap policy is very flexible allowing users to setup their
163 portmap processes in as secure a method as possible.
164
165 STANDARD FILE CONTEXT
166
167 SELinux defines the file context types for the portmap, if you wanted
168 to store files with these types in a diffent paths, you need to execute
169 the semanage command to specify alternate labeling and then use re‐
170 storecon to put the labels on disk.
171
172 semanage fcontext -a -t portmap_var_run_t '/srv/myportmap_con‐
173 tent(/.*)?'
174 restorecon -R -v /srv/myportmap_content
175
176 Note: SELinux often uses regular expressions to specify labels that
177 match multiple files.
178
179 The following file types are defined for portmap:
180
181
182
183 portmap_exec_t
184
185 - Set files with the portmap_exec_t type, if you want to transition an
186 executable to the portmap_t domain.
187
188
189 Paths:
190 /sbin/portmap, /usr/sbin/portmap
191
192
193 portmap_helper_exec_t
194
195 - Set files with the portmap_helper_exec_t type, if you want to transi‐
196 tion an executable to the portmap_helper_t domain.
197
198
199 Paths:
200 /sbin/pmap_set, /sbin/pmap_dump, /usr/sbin/pmap_set,
201 /usr/sbin/pmap_dump
202
203
204 portmap_initrc_exec_t
205
206 - Set files with the portmap_initrc_exec_t type, if you want to transi‐
207 tion an executable to the portmap_initrc_t domain.
208
209
210
211 portmap_tmp_t
212
213 - Set files with the portmap_tmp_t type, if you want to store portmap
214 temporary files in the /tmp directories.
215
216
217
218 portmap_var_run_t
219
220 - Set files with the portmap_var_run_t type, if you want to store the
221 portmap files under the /run or /var/run directory.
222
223
224 Paths:
225 /var/run/portmap_mapping, /var/run/portmap.upgrade-state
226
227
228 Note: File context can be temporarily modified with the chcon command.
229 If you want to permanently change the file context you need to use the
230 semanage fcontext command. This will modify the SELinux labeling data‐
231 base. You will need to use restorecon to apply the labels.
232
233
235 semanage fcontext can also be used to manipulate default file context
236 mappings.
237
238 semanage permissive can also be used to manipulate whether or not a
239 process type is permissive.
240
241 semanage module can also be used to enable/disable/install/remove pol‐
242 icy modules.
243
244 semanage port can also be used to manipulate the port definitions
245
246 semanage boolean can also be used to manipulate the booleans
247
248
249 system-config-selinux is a GUI tool available to customize SELinux pol‐
250 icy settings.
