6 boinc_selinux - Security Enhanced Linux Policy for the boinc processes
7
9 Security-Enhanced Linux secures the boinc processes via flexible manda‐
10 tory access control.
11
12 The boinc processes execute with the boinc_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep boinc_t
19
20
21
23 The boinc_t SELinux type can be entered via the boinc_exec_t file type.
24
25 The default entrypoint paths for the boinc_t domain are the following:
26
27 /usr/bin/boinc_client
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 boinc policy is very flexible allowing users to setup their boinc pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for boinc:
40
41 boinc_t, boinc_project_t
42
43 Note: semanage permissive -a boinc_t can be used to make the process
44 type boinc_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. boinc
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run boinc with the tightest access possible.

56 If you want to allow all daemons to write corefiles to /, you must turn
57 on the allow_daemons_dump_core boolean. Disabled by default.

129 SELinux defines port types to represent TCP and UDP ports.
130
131 You can see the types associated with a port by using the following
132 command:
133
134 semanage port -l
135
136
137 Policy governs the access confined processes have to these ports.
138 SELinux boinc policy is very flexible allowing users to setup their
139 boinc processes in as secure a method as possible.
140
141 The following port types are defined for boinc:
142
143
144 boinc_port_t
145
146
147
148 Default Defined Ports:
149 tcp 31416
150
152 The SELinux process type boinc_t can manage files labeled with the fol‐
153 lowing file types. The paths listed are the default paths for these
154 file types. Note the processes UID still need to have DAC permissions.

230 SELinux requires files to have an extended attribute to define the file
231 type.
232
233 You can see the context of a file using the -Z option to ls
234
235 Policy governs the access confined processes have to these files.
236 SELinux boinc policy is very flexible allowing users to setup their
237 boinc processes in as secure a method as possible.
238
239 EQUIVALENCE DIRECTORIES
240
241
242 boinc policy stores data with multiple different file context types
243 under the /var/lib/boinc directory. If you would like to store the
244 data in a different directory you can use the semanage command to cre‐
245 ate an equivalence mapping. If you wanted to store this data under the
246 /srv dirctory you would execute the following command:
247
248 semanage fcontext -a -e /var/lib/boinc /srv/boinc
249 restorecon -R -v /srv/boinc
250
251 STANDARD FILE CONTEXT
252
253 SELinux defines the file context types for the boinc, if you wanted to
254 store files with these types in a diffent paths, you need to execute
255 the semanage command to sepecify alternate labeling and then use
256 restorecon to put the labels on disk.
257
258 semanage fcontext -a -t boinc_var_lib_t '/srv/myboinc_content(/.*)?'
259 restorecon -R -v /srv/myboinc_content
260
261 Note: SELinux often uses regular expressions to specify labels that
262 match multiple files.
263
264 The following file types are defined for boinc:
265
266
267
268 boinc_exec_t
269
270 - Set files with the boinc_exec_t type, if you want to transition an
271 executable to the boinc_t domain.
272
273
274
275 boinc_initrc_exec_t
276
277 - Set files with the boinc_initrc_exec_t type, if you want to transi‐
278 tion an executable to the boinc_initrc_t domain.
279
280
281
282 boinc_project_tmp_t
283
284 - Set files with the boinc_project_tmp_t type, if you want to store
285 boinc project temporary files in the /tmp directories.
286
287
288
289 boinc_project_var_lib_t
290
291 - Set files with the boinc_project_var_lib_t type, if you want to store
292 the boinc project files under the /var/lib directory.
293
294
295 Paths:
296 /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
297
298
299 boinc_tmp_t
300
301 - Set files with the boinc_tmp_t type, if you want to store boinc tem‐
302 porary files in the /tmp directories.
303
304
305
306 boinc_tmpfs_t
307
308 - Set files with the boinc_tmpfs_t type, if you want to store boinc
309 files on a tmpfs file system.
310
311
312
313 boinc_var_lib_t
314
315 - Set files with the boinc_var_lib_t type, if you want to store the
316 boinc files under the /var/lib directory.
317
318
319
320 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
325
327 semanage fcontext can also be used to manipulate default file context
328 mappings.
329
330 semanage permissive can also be used to manipulate whether or not a
331 process type is permissive.
332
333 semanage module can also be used to enable/disable/install/remove pol‐
334 icy modules.
335
336 semanage port can also be used to manipulate the port definitions
337
338 semanage boolean can also be used to manipulate the booleans
339
340
341 system-config-selinux is a GUI tool available to customize SELinux pol‐
342 icy settings.
