6 restorecond_selinux - Security Enhanced Linux Policy for the restore‐
7 cond processes
8
10 Security-Enhanced Linux secures the restorecond processes via flexible
11 mandatory access control.
12 The restorecond processes execute with the restorecond_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep restorecond_t
20
24 The restorecond_t SELinux type can be entered via the restore‐
25 cond_exec_t file type.
26 The default entrypoint paths for the restorecond_t domain are the fol‐
28 lowing:
29 /usr/sbin/restorecond
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 restorecond policy is very flexible allowing users to setup their
40 restorecond processes in as secure a method as possible.
41 The following process types are defined for restorecond:
43 restorecond_t
45 Note: semanage permissive -a restorecond_t can be used to make the
47 process type restorecond_t permissive. SELinux does not deny access to
48 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 restorecond policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run restorecond with the tight‐
56 est access possible.

122 If you want to allow all domains to execute in fips_mode, you must turn
126 on the fips_mode boolean. Enabled by default.
127 setsebool -P fips_mode 1
129 If you want to enable reading of urandom for all domains, you must turn
133 on the global_ssp boolean. Disabled by default.
134 setsebool -P global_ssp 1
136 If you want to enable support for upstart as the init program, you must
140 turn on the init_upstart boolean. Enabled by default.
141 setsebool -P init_upstart 1
143 If you want to allow confined applications to use nscd shared memory,
147 you must turn on the nscd_use_shm boolean. Enabled by default.
148 setsebool -P nscd_use_shm 1

154 The SELinux process type restorecond_t can manage files labeled with
155 the following file types. The paths listed are the default paths for
156 these file types. Note the processes UID still need to have DAC per‐
157 missions.

225 SELinux requires files to have an extended attribute to define the file
226 type.
227 You can see the context of a file using the -Z option to ls
229 Policy governs the access confined processes have to these files.
231 SELinux restorecond policy is very flexible allowing users to setup
232 their restorecond processes in as secure a method as possible.
233 STANDARD FILE CONTEXT
235 SELinux defines the file context types for the restorecond, if you
237 wanted to store files with these types in a diffent paths, you need to
238 execute the semanage command to sepecify alternate labeling and then
239 use restorecon to put the labels on disk.
240 semanage fcontext -a -t restorecond_var_run_t '/srv/myrestorecond_con‐
242 tent(/.*)?'
243 restorecon -R -v /srv/myrestorecond_content
244 Note: SELinux often uses regular expressions to specify labels that
246 match multiple files.
247 The following file types are defined for restorecond:
249 restorecond_exec_t
253 - Set files with the restorecond_exec_t type, if you want to transition
255 an executable to the restorecond_t domain.
256 restorecond_var_run_t
260 - Set files with the restorecond_var_run_t type, if you want to store
262 the restorecond files under the /run or /var/run directory.
263 Note: File context can be temporarily modified with the chcon command.
267 If you want to permanently change the file context you need to use the
268 semanage fcontext command. This will modify the SELinux labeling data‐
269 base. You will need to use restorecon to apply the labels.
270
273 semanage fcontext can also be used to manipulate default file context
274 mappings.
275 semanage permissive can also be used to manipulate whether or not a
277 process type is permissive.
278 semanage module can also be used to enable/disable/install/remove pol‐
280 icy modules.
281 semanage boolean can also be used to manipulate the booleans
283 system-config-selinux is a GUI tool available to customize SELinux pol‐
286 icy settings.
