6 portreserve_selinux - Security Enhanced Linux Policy for the portre‐
7 serve processes
8
10 Security-Enhanced Linux secures the portreserve processes via flexible
11 mandatory access control.
12 The portreserve processes execute with the portreserve_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 portreserve_t
20
24 The portreserve_t SELinux type can be entered via the portre‐
25 serve_exec_t file type.
26 The default entrypoint paths for the portreserve_t domain are the fol‐
28 lowing:
29 /sbin/portreserve, /usr/sbin/portreserve
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 portreserve policy is very flexible allowing users to setup their
40 portreserve processes in as secure a method as possible.
41 The following process types are defined for portreserve:
43 portreserve_t
45 Note: semanage permissive -a portreserve_t can be used to make the
47 process type portreserve_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. portre‐
54 serve policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run portreserve with the tightest
56 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‐

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 portreserve_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.
175 cluster_conf_t
177 /etc/cluster(/.*)?

217 SELinux requires files to have an extended attribute to define the file
218 type.
219 You can see the context of a file using the -Z option to ls
221 Policy governs the access confined processes have to these files.
223 SELinux portreserve policy is very flexible allowing users to setup
224 their portreserve processes in as secure a method as possible.
225 STANDARD FILE CONTEXT
227 SELinux defines the file context types for the portreserve, if you
229 wanted to store files with these types in a diffent paths, you need to
230 execute the semanage command to sepecify alternate labeling and then
231 use restorecon to put the labels on disk.
232 semanage fcontext -a -t portreserve_var_run_t '/srv/myportreserve_con‐
234 tent(/.*)?'
235 restorecon -R -v /srv/myportreserve_content
236 Note: SELinux often uses regular expressions to specify labels that
238 match multiple files.
239 The following file types are defined for portreserve:
241 portreserve_etc_t
245 - Set files with the portreserve_etc_t type, if you want to store
247 portreserve files in the /etc directories.
248 portreserve_exec_t
252 - Set files with the portreserve_exec_t type, if you want to transition
254 an executable to the portreserve_t domain.
255 Paths:
258 /sbin/portreserve, /usr/sbin/portreserve
259 portreserve_initrc_exec_t
262 - Set files with the portreserve_initrc_exec_t type, if you want to
264 transition an executable to the portreserve_initrc_t domain.
265 portreserve_var_run_t
269 - Set files with the portreserve_var_run_t type, if you want to store
271 the portreserve files under the /run or /var/run directory.
272 Note: File context can be temporarily modified with the chcon command.
276 If you want to permanently change the file context you need to use the
277 semanage fcontext command. This will modify the SELinux labeling data‐
278 base. You will need to use restorecon to apply the labels.
279
282 semanage fcontext can also be used to manipulate default file context
283 mappings.
284 semanage permissive can also be used to manipulate whether or not a
286 process type is permissive.
287 semanage module can also be used to enable/disable/install/remove pol‐
289 icy modules.
290 semanage boolean can also be used to manipulate the booleans
292 system-config-selinux is a GUI tool available to customize SELinux pol‐
295 icy settings.
