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 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 For example:
18 ps -eZ | grep portmap_helper_t
20
24 The portmap_helper_t SELinux type can be entered via the
25 portmap_helper_exec_t file type.
26 The default entrypoint paths for the portmap_helper_t domain are the
28 following:
29 /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 You can see the context of a process using the -Z option to ps
38 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 The following process types are defined for portmap_helper:
44 portmap_helper_t
46 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
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 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 setsebool -P fips_mode 1

69 The SELinux process type portmap_helper_t can manage files labeled with
70 the following file types. The paths listed are the default paths for
71 these file types. Note the processes UID still need to have DAC per‐
72 missions.
73 initrc_var_run_t
75 /var/run/utmp
77 /var/run/random-seed
78 /var/run/runlevel.dir
79 /var/run/setmixer_flag
80 portmap_var_run_t
82 /var/run/portmap_mapping
84 /var/run/portmap.upgrade-state
85 var_run_t
87 /run/.*
89 /var/run/.*
90 /run
91 /var/run
92 /var/run
93 /var/spool/postfix/pid

97 SELinux requires files to have an extended attribute to define the file
98 type.
99 You can see the context of a file using the -Z option to ls
101 Policy governs the access confined processes have to these files.
103 SELinux portmap_helper policy is very flexible allowing users to setup
104 their portmap_helper processes in as secure a method as possible.
105 The following file types are defined for portmap_helper:
107 portmap_helper_exec_t
111 - Set files with the portmap_helper_exec_t type, if you want to transi‐
113 tion an executable to the portmap_helper_t domain.
114 Paths:
117 /sbin/pmap_set, /sbin/pmap_dump, /usr/sbin/pmap_set,
118 /usr/sbin/pmap_dump
119 Note: File context can be temporarily modified with the chcon command.
122 If you want to permanently change the file context you need to use the
123 semanage fcontext command. This will modify the SELinux labeling data‐
124 base. You will need to use restorecon to apply the labels.
125
128 semanage fcontext can also be used to manipulate default file context
129 mappings.
130 semanage permissive can also be used to manipulate whether or not a
132 process type is permissive.
133 semanage module can also be used to enable/disable/install/remove pol‐
135 icy modules.
136 semanage boolean can also be used to manipulate the booleans
138 system-config-selinux is a GUI tool available to customize SELinux pol‐
141 icy settings.
