NAME

6       boinc_selinux - Security Enhanced Linux Policy for the boinc processes
7

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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.
53
54
55
56       If you want to determine whether boinc can execmem/execstack, you  must

PORT TYPES

152       SELinux defines port types to represent TCP and UDP ports.
153
154       You  can  see  the  types associated with a port by using the following
155       command:
156
157       semanage port -l
158
159
160       Policy governs the access  confined  processes  have  to  these  ports.
161       SELinux  boinc  policy  is  very flexible allowing users to setup their
162       boinc processes in as secure a method as possible.
163
164       The following port types are defined for boinc:
165
166
167       boinc_client_port_t
168
169
170
171       Default Defined Ports:
172                 tcp 1043
173                 udp 1034
174
175
176       boinc_port_t
177
178
179
180       Default Defined Ports:
181                 tcp 31416
182

MANAGED FILES

184       The SELinux process type boinc_t can manage files labeled with the fol‐
185       lowing  file  types.   The paths listed are the default paths for these
186       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

244       SELinux requires files to have an extended attribute to define the file
245       type.
246
247       You can see the context of a file using the -Z option to ls
248
249       Policy  governs  the  access  confined  processes  have to these files.
250       SELinux boinc policy is very flexible allowing  users  to  setup  their
251       boinc processes in as secure a method as possible.
252
253       EQUIVALENCE DIRECTORIES
254
255
256       boinc  policy  stores  data  with multiple different file context types
257       under the /var/lib/boinc directory.  If you would  like  to  store  the
258       data  in a different directory you can use the semanage command to cre‐
259       ate an equivalence mapping.  If you wanted to store this data under the
260       /srv dirctory you would execute the following command:
261
262       semanage fcontext -a -e /var/lib/boinc /srv/boinc
263       restorecon -R -v /srv/boinc
264
265       STANDARD FILE CONTEXT
266
267       SELinux  defines the file context types for the boinc, if you wanted to
268       store files with these types in a diffent paths, you  need  to  execute
269       the  semanage  command  to  sepecify  alternate  labeling  and then use
270       restorecon to put the labels on disk.
271
272       semanage fcontext -a -t boinc_var_lib_t '/srv/myboinc_content(/.*)?'
273       restorecon -R -v /srv/myboinc_content
274
275       Note: SELinux often uses regular expressions  to  specify  labels  that
276       match multiple files.
277
278       The following file types are defined for boinc:
279
280
281
282       boinc_exec_t
283
284       -  Set  files  with the boinc_exec_t type, if you want to transition an
285       executable to the boinc_t domain.
286
287
288
289       boinc_initrc_exec_t
290
291       - Set files with the boinc_initrc_exec_t type, if you want  to  transi‐
292       tion an executable to the boinc_initrc_t domain.
293
294
295
296       boinc_log_t
297
298       - Set files with the boinc_log_t type, if you want to treat the data as
299       boinc log data, usually stored under the /var/log directory.
300
301
302
303       boinc_project_tmp_t
304
305       - Set files with the boinc_project_tmp_t type, if  you  want  to  store
306       boinc project temporary files in the /tmp directories.
307
308
309
310       boinc_project_var_lib_t
311
312       - Set files with the boinc_project_var_lib_t type, if you want to store
313       the boinc project files under the /var/lib directory.
314
315
316       Paths:
317            /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
318
319
320       boinc_tmp_t
321
322       - Set files with the boinc_tmp_t type, if you want to store boinc  tem‐
323       porary files in the /tmp directories.
324
325
326
327       boinc_tmpfs_t
328
329       -  Set  files  with  the boinc_tmpfs_t type, if you want to store boinc
330       files on a tmpfs file system.
331
332
333
334       boinc_unit_file_t
335
336       - Set files with the boinc_unit_file_t type, if you want to  treat  the
337       files as boinc unit content.
338
339
340
341       boinc_var_lib_t
342
343       -  Set  files  with  the boinc_var_lib_t type, if you want to store the
344       boinc files under the /var/lib directory.
345
346
347
348       Note: File context can be temporarily modified with the chcon  command.
349       If  you want to permanently change the file context you need to use the
350       semanage fcontext command.  This will modify the SELinux labeling data‐
351       base.  You will need to use restorecon to apply the labels.
352
353

COMMANDS

355       semanage  fcontext  can also be used to manipulate default file context
356       mappings.
357
358       semanage permissive can also be used to manipulate  whether  or  not  a
359       process type is permissive.
360
361       semanage  module can also be used to enable/disable/install/remove pol‐
362       icy modules.
363
364       semanage port can also be used to manipulate the port definitions
365
366       semanage boolean can also be used to manipulate the booleans
367
368
369       system-config-selinux is a GUI tool available to customize SELinux pol‐
370       icy settings.
