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.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

121 you must turn on the domain_fd_use boolean. Enabled by default.
122 setsebool -P domain_fd_use 1
124 If you want to allow all domains to have the kernel load modules, you
128 must turn on the domain_kernel_load_modules boolean. Disabled by
129 default.
130 setsebool -P domain_kernel_load_modules 1
132 If you want to allow all domains to execute in fips_mode, you must turn
136 on the fips_mode boolean. Enabled by default.
137 setsebool -P fips_mode 1
139 If you want to enable reading of urandom for all domains, you must turn
143 on the global_ssp boolean. Disabled by default.
144 setsebool -P global_ssp 1
146 If you want to allow confined applications to run with kerberos, you
150 must turn on the kerberos_enabled boolean. Enabled by default.
151 setsebool -P kerberos_enabled 1
153 If you want to allow system to run with NIS, you must turn on the
157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1
160 If you want to allow confined applications to use nscd shared memory,
164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1

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

221 SELinux requires files to have an extended attribute to define the file
222 type.
223 You can see the context of a file using the -Z option to ls
225 Policy governs the access confined processes have to these files.
227 SELinux restorecond policy is very flexible allowing users to setup
228 their restorecond processes in as secure a method as possible.
229 STANDARD FILE CONTEXT
231 SELinux defines the file context types for the restorecond, if you
233 wanted to store files with these types in a diffent paths, you need to
234 execute the semanage command to sepecify alternate labeling and then
235 use restorecon to put the labels on disk.
236 semanage fcontext -a -t restorecond_var_run_t '/srv/myrestorecond_con‐
238 tent(/.*)?'
239 restorecon -R -v /srv/myrestorecond_content
240 Note: SELinux often uses regular expressions to specify labels that
242 match multiple files.
243 The following file types are defined for restorecond:
245 restorecond_exec_t
249 - Set files with the restorecond_exec_t type, if you want to transition
251 an executable to the restorecond_t domain.
252 restorecond_var_run_t
256 - Set files with the restorecond_var_run_t type, if you want to store
258 the restorecond files under the /run or /var/run directory.
259 Note: File context can be temporarily modified with the chcon command.
263 If you want to permanently change the file context you need to use the
264 semanage fcontext command. This will modify the SELinux labeling data‐
265 base. You will need to use restorecon to apply the labels.
266
269 semanage fcontext can also be used to manipulate default file context
270 mappings.
271 semanage permissive can also be used to manipulate whether or not a
273 process type is permissive.
274 semanage module can also be used to enable/disable/install/remove pol‐
276 icy modules.
277 semanage boolean can also be used to manipulate the booleans
279 system-config-selinux is a GUI tool available to customize SELinux pol‐
282 icy settings.
