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.
57 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 setsebool -P fips_mode 1
64
68 SELinux defines port types to represent TCP and UDP ports.
69 You can see the types associated with a port by using the following
71 command:
72 semanage port -l
74 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 The following port types are defined for portmap:
81 portmap_port_t
84 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.

138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 Policy governs the access confined processes have to these files.
144 SELinux portmap policy is very flexible allowing users to setup their
145 portmap processes in as secure a method as possible.
146 STANDARD FILE CONTEXT
148 SELinux defines the file context types for the portmap, if you wanted
150 to store files with these types in a diffent paths, you need to execute
151 the semanage command to sepecify alternate labeling and then use
152 restorecon to put the labels on disk.
153 semanage fcontext -a -t portmap_var_run_t '/srv/myportmap_con‐
155 tent(/.*)?'
156 restorecon -R -v /srv/myportmap_content
157 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160 The following file types are defined for portmap:
162 portmap_exec_t
166 - Set files with the portmap_exec_t type, if you want to transition an
168 executable to the portmap_t domain.
169 Paths:
172 /sbin/portmap, /usr/sbin/portmap
173 portmap_helper_exec_t
176 - Set files with the portmap_helper_exec_t type, if you want to transi‐
178 tion an executable to the portmap_helper_t domain.
179 Paths:
182 /sbin/pmap_set, /sbin/pmap_dump, /usr/sbin/pmap_set,
183 /usr/sbin/pmap_dump
184 portmap_initrc_exec_t
187 - Set files with the portmap_initrc_exec_t type, if you want to transi‐
189 tion an executable to the portmap_initrc_t domain.
190 portmap_tmp_t
194 - Set files with the portmap_tmp_t type, if you want to store portmap
196 temporary files in the /tmp directories.
197 portmap_var_run_t
201 - Set files with the portmap_var_run_t type, if you want to store the
203 portmap files under the /run or /var/run directory.
204 Paths:
207 /var/run/portmap_mapping, /var/run/portmap.upgrade-state
208 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225 semanage port can also be used to manipulate the port definitions
227 semanage boolean can also be used to manipulate the booleans
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
