6 portmap_helper_selinux - Security Enhanced Linux Policy for the
7 portmap_helper processes
8
10 Security-Enhanced Linux secures the portmap_helper processes via flexi‐
11 ble mandatory access control.
12
13 The portmap_helper processes execute with the portmap_helper_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep portmap_helper_t
20
21
22
24 The portmap_helper_t SELinux type can be entered via the
25 portmap_helper_exec_t file type.
26
27 The default entrypoint paths for the portmap_helper_t domain are the
28 following:
29
30 /sbin/pmap_set, /sbin/pmap_dump, /usr/sbin/pmap_set,
31 /usr/sbin/pmap_dump
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 portmap_helper policy is very flexible allowing users to setup their
41 portmap_helper processes in as secure a method as possible.
42
43 The following process types are defined for portmap_helper:
44
45 portmap_helper_t
46
47 Note: semanage permissive -a portmap_helper_t can be used to make the
48 process type portmap_helper_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
52
54 SELinux policy is customizable based on least access required.
55 portmap_helper policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run portmap_helper with the
57 tightest access possible.
58
59
60
61 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63
64 setsebool -P fips_mode 1
65
66
67
68 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70
71 setsebool -P nis_enabled 1
72
73
74
76 The SELinux process type portmap_helper_t can manage files labeled with
77 the following file types. The paths listed are the default paths for
78 these file types. Note the processes UID still need to have DAC per‐
79 missions.

118 SELinux requires files to have an extended attribute to define the file
119 type.
120
121 You can see the context of a file using the -Z option to ls
122
123 Policy governs the access confined processes have to these files.
124 SELinux portmap_helper policy is very flexible allowing users to setup
125 their portmap_helper processes in as secure a method as possible.
126
127 STANDARD FILE CONTEXT
128
129 SELinux defines the file context types for the portmap_helper, if you
130 wanted to store files with these types in a different paths, you need
131 to execute the semanage command to specify alternate labeling and then
132 use restorecon to put the labels on disk.
133
134 semanage fcontext -a -t portmap_helper_exec_t '/srv/portmap_helper/con‐
135 tent(/.*)?'
136 restorecon -R -v /srv/myportmap_helper_content
137
138 Note: SELinux often uses regular expressions to specify labels that
139 match multiple files.
140
141 The following file types are defined for portmap_helper:
142
143
144
145 portmap_helper_exec_t
146
147 - Set files with the portmap_helper_exec_t type, if you want to transi‐
148 tion an executable to the portmap_helper_t domain.
149
150
151 Paths:
152 /sbin/pmap_set, /sbin/pmap_dump, /usr/sbin/pmap_set,
153 /usr/sbin/pmap_dump
154
155
156 Note: File context can be temporarily modified with the chcon command.
157 If you want to permanently change the file context you need to use the
158 semanage fcontext command. This will modify the SELinux labeling data‐
159 base. You will need to use restorecon to apply the labels.
160
161
163 semanage fcontext can also be used to manipulate default file context
164 mappings.
165
166 semanage permissive can also be used to manipulate whether or not a
167 process type is permissive.
168
169 semanage module can also be used to enable/disable/install/remove pol‐
170 icy modules.
171
172 semanage boolean can also be used to manipulate the booleans
173
174
175 system-config-selinux is a GUI tool available to customize SELinux pol‐
176 icy settings.
