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 /usr/sbin/pmap_set, /usr/sbin/pmap_dump
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_helper policy is very flexible allowing users to setup their
40 portmap_helper processes in as secure a method as possible.
41 The following process types are defined for portmap_helper:
43 portmap_helper_t
45 Note: semanage permissive -a portmap_helper_t can be used to make the
47 process type portmap_helper_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 portmap_helper policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run portmap_helper with the
56 tightest access possible.
57 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to allow sysadm to debug or ptrace all processes, you must
76 turn on the allow_ptrace boolean. Disabled by default.
77 setsebool -P allow_ptrace 1
79 If you want to allow system to run with NIS, you must turn on the
83 allow_ypbind boolean. Disabled by default.
84 setsebool -P allow_ypbind 1
86 If you want to allow all domains to have the kernel load modules, you
90 must turn on the domain_kernel_load_modules boolean. Disabled by
91 default.
92 setsebool -P domain_kernel_load_modules 1
94 If you want to allow all domains to execute in fips_mode, you must turn
98 on the fips_mode boolean. Enabled by default.
99 setsebool -P fips_mode 1
101 If you want to enable reading of urandom for all domains, you must turn
105 on the global_ssp boolean. Disabled by default.
106 setsebool -P global_ssp 1

112 The SELinux process type portmap_helper_t can manage files labeled with
113 the following file types. The paths listed are the default paths for
114 these file types. Note the processes UID still need to have DAC per‐
115 missions.
116 initrc_tmp_t
118 initrc_var_run_t
121 /var/run/utmp
123 /var/run/random-seed
124 /var/run/runlevel.dir

162 SELinux requires files to have an extended attribute to define the file
163 type.
164 You can see the context of a file using the -Z option to ls
166 Policy governs the access confined processes have to these files.
168 SELinux portmap_helper policy is very flexible allowing users to setup
169 their portmap_helper processes in as secure a method as possible.
170 The following file types are defined for portmap_helper:
172 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 /usr/sbin/pmap_set, /usr/sbin/pmap_dump
183 Note: File context can be temporarily modified with the chcon command.
186 If you want to permanently change the file context you need to use the
187 semanage fcontext command. This will modify the SELinux labeling data‐
188 base. You will need to use restorecon to apply the labels.
189
192 semanage fcontext can also be used to manipulate default file context
193 mappings.
194 semanage permissive can also be used to manipulate whether or not a
196 process type is permissive.
197 semanage module can also be used to enable/disable/install/remove pol‐
199 icy modules.
200 semanage boolean can also be used to manipulate the booleans
202 system-config-selinux is a GUI tool available to customize SELinux pol‐
205 icy settings.
