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, /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
57       turn on the boinc_execmem boolean. Enabled by default.
58
59       setsebool -P boinc_execmem 1
60
61
62
63       If you want to allow all domains to execute in fips_mode, you must turn
64       on the fips_mode boolean. Enabled by default.
65
66       setsebool -P fips_mode 1
67
68
69

PORT TYPES

71       SELinux defines port types to represent TCP and UDP ports.
72
73       You can see the types associated with a port  by  using  the  following
74       command:
75
76       semanage port -l
77
78
79       Policy  governs  the  access  confined  processes  have to these ports.
80       SELinux boinc policy is very flexible allowing  users  to  setup  their
81       boinc processes in as secure a method as possible.
82
83       The following port types are defined for boinc:
84
85
86       boinc_client_port_t
87
88
89
90       Default Defined Ports:
91                 tcp 1043
92                 udp 1034
93
94
95       boinc_port_t
96
97
98
99       Default Defined Ports:
100                 tcp 31416
101

MANAGED FILES

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

FILE CONTEXTS

181       SELinux requires files to have an extended attribute to define the file
182       type.
183
184       You can see the context of a file using the -Z option to ls
185
186       Policy governs the access  confined  processes  have  to  these  files.
187       SELinux  boinc  policy  is  very flexible allowing users to setup their
188       boinc processes in as secure a method as possible.
189
190       EQUIVALENCE DIRECTORIES
191
192
193       boinc policy stores data with multiple different file context types un‐
194       der  the /var/lib/boinc directory.  If you would like to store the data
195       in a different directory you can use the semanage command to create  an
196       equivalence  mapping.   If you wanted to store this data under the /srv
197       directory you would execute the following command:
198
199       semanage fcontext -a -e /var/lib/boinc /srv/boinc
200       restorecon -R -v /srv/boinc
201
202       STANDARD FILE CONTEXT
203
204       SELinux defines the file context types for the boinc, if you wanted  to
205       store  files  with  these types in a diffent paths, you need to execute
206       the semanage command to sepecify alternate labeling and  then  use  re‐
207       storecon to put the labels on disk.
208
209       semanage  fcontext  -a  -t  boinc_project_var_lib_t  '/srv/myboinc_con‐
210       tent(/.*)?'
211       restorecon -R -v /srv/myboinc_content
212
213       Note: SELinux often uses regular expressions  to  specify  labels  that
214       match multiple files.
215
216       The following file types are defined for boinc:
217
218
219
220       boinc_exec_t
221
222       -  Set  files  with the boinc_exec_t type, if you want to transition an
223       executable to the boinc_t domain.
224
225
226       Paths:
227            /usr/bin/boinc, /usr/bin/boinc_client
228
229
230       boinc_initrc_exec_t
231
232       - Set files with the boinc_initrc_exec_t type, if you want  to  transi‐
233       tion an executable to the boinc_initrc_t domain.
234
235
236
237       boinc_log_t
238
239       - Set files with the boinc_log_t type, if you want to treat the data as
240       boinc log data, usually stored under the /var/log directory.
241
242
243       Paths:
244            /var/log/boinc.log.*, /var/log/boincerr.log.*
245
246
247       boinc_project_tmp_t
248
249       - Set files with the boinc_project_tmp_t type, if  you  want  to  store
250       boinc project temporary files in the /tmp directories.
251
252
253
254       boinc_project_var_lib_t
255
256       - Set files with the boinc_project_var_lib_t type, if you want to store
257       the boinc project files under the /var/lib directory.
258
259
260       Paths:
261            /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
262
263
264       boinc_tmp_t
265
266       - Set files with the boinc_tmp_t type, if you want to store boinc  tem‐
267       porary files in the /tmp directories.
268
269
270
271       boinc_tmpfs_t
272
273       -  Set  files  with  the boinc_tmpfs_t type, if you want to store boinc
274       files on a tmpfs file system.
275
276
277
278       boinc_unit_file_t
279
280       - Set files with the boinc_unit_file_t type, if you want to  treat  the
281       files as boinc unit content.
282
283
284
285       boinc_var_lib_t
286
287       -  Set  files  with  the boinc_var_lib_t type, if you want to store the
288       boinc files under the /var/lib directory.
289
290
291       Paths:
292            /var/lib/boinc(/.*)?,   /var/lib/boinc-client(/.*)?,   /etc/boinc-
293            client/global_prefs_override.xml
294
295
296       Note:  File context can be temporarily modified with the chcon command.
297       If you want to permanently change the file context you need to use  the
298       semanage fcontext command.  This will modify the SELinux labeling data‐
299       base.  You will need to use restorecon to apply the labels.
300
301

COMMANDS

303       semanage fcontext can also be used to manipulate default  file  context
304       mappings.
305
306       semanage  permissive  can  also  be used to manipulate whether or not a
307       process type is permissive.
308
309       semanage module can also be used to enable/disable/install/remove  pol‐
310       icy modules.
311
312       semanage port can also be used to manipulate the port definitions
313
314       semanage boolean can also be used to manipulate the booleans
315
316
317       system-config-selinux is a GUI tool available to customize SELinux pol‐
318       icy settings.
