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

171 The SELinux process type piranha_web_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.

235 SELinux requires files to have an extended attribute to define the file
236 type.
237 You can see the context of a file using the -Z option to ls
239 Policy governs the access confined processes have to these files.
241 SELinux piranha_web policy is very flexible allowing users to setup
242 their piranha_web processes in as secure a method as possible.
243 EQUIVALENCE DIRECTORIES
245 piranha_web policy stores data with multiple different file context
248 types under the /var/lib/luci directory. If you would like to store
249 the data in a different directory you can use the semanage command to
250 create an equivalence mapping. If you wanted to store this data under
251 the /srv dirctory you would execute the following command:
252 semanage fcontext -a -e /var/lib/luci /srv/luci
254 restorecon -R -v /srv/luci
255 STANDARD FILE CONTEXT
257 SELinux defines the file context types for the piranha_web, if you
259 wanted to store files with these types in a diffent paths, you need to
260 execute the semanage command to sepecify alternate labeling and then
261 use restorecon to put the labels on disk.
262 semanage fcontext -a -t piranha_web_var_run_t '/srv/mypiranha_web_con‐
264 tent(/.*)?'
265 restorecon -R -v /srv/mypiranha_web_content
266 Note: SELinux often uses regular expressions to specify labels that
268 match multiple files.
269 The following file types are defined for piranha_web:
271 piranha_web_conf_t
275 - Set files with the piranha_web_conf_t type, if you want to treat the
277 files as piranha web configuration data, usually stored under the /etc
278 directory.
279 Paths:
282 /var/lib/luci/etc(/.*)?, /var/lib/luci/cert(/.*)?
283 piranha_web_data_t
286 - Set files with the piranha_web_data_t type, if you want to treat the
288 files as piranha web content.
289 piranha_web_exec_t
293 - Set files with the piranha_web_exec_t type, if you want to transition
295 an executable to the piranha_web_t domain.
296 piranha_web_tmp_t
300 - Set files with the piranha_web_tmp_t type, if you want to store
302 piranha web temporary files in the /tmp directories.
303 piranha_web_tmpfs_t
307 - Set files with the piranha_web_tmpfs_t type, if you want to store
309 piranha web files on a tmpfs file system.
310 piranha_web_var_run_t
314 - Set files with the piranha_web_var_run_t type, if you want to store
316 the piranha web files under the /run or /var/run directory.
317 Note: File context can be temporarily modified with the chcon command.
321 If you want to permanently change the file context you need to use the
322 semanage fcontext command. This will modify the SELinux labeling data‐
323 base. You will need to use restorecon to apply the labels.
324
327 semanage fcontext can also be used to manipulate default file context
328 mappings.
329 semanage permissive can also be used to manipulate whether or not a
331 process type is permissive.
332 semanage module can also be used to enable/disable/install/remove pol‐
334 icy modules.
335 semanage boolean can also be used to manipulate the booleans
337 system-config-selinux is a GUI tool available to customize SELinux pol‐
340 icy settings.
