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

163       SELinux requires files to have an extended attribute to define the file
164       type.
165
166       You can see the context of a file using the -Z option to ls
167
168       Policy governs the access  confined  processes  have  to  these  files.
169       SELinux  boinc  policy  is  very flexible allowing users to setup their
170       boinc processes in as secure a method as possible.
171
172       EQUIVALENCE DIRECTORIES
173
174
175       boinc policy stores data with multiple  different  file  context  types
176       under  the  /var/lib/boinc  directory.   If you would like to store the
177       data in a different directory you can use the semanage command to  cre‐
178       ate an equivalence mapping.  If you wanted to store this data under the
179       /srv directory you would execute the following command:
180
181       semanage fcontext -a -e /var/lib/boinc /srv/boinc
182       restorecon -R -v /srv/boinc
183
184       STANDARD FILE CONTEXT
185
186       SELinux defines the file context types for the boinc, if you wanted  to
187       store  files  with  these types in a diffent paths, you need to execute
188       the semanage command  to  sepecify  alternate  labeling  and  then  use
189       restorecon to put the labels on disk.
190
191       semanage  fcontext  -a  -t  boinc_project_var_lib_t  '/srv/myboinc_con‐
192       tent(/.*)?'
193       restorecon -R -v /srv/myboinc_content
194
195       Note: SELinux often uses regular expressions  to  specify  labels  that
196       match multiple files.
197
198       The following file types are defined for boinc:
199
200
201
202       boinc_exec_t
203
204       -  Set  files  with the boinc_exec_t type, if you want to transition an
205       executable to the boinc_t domain.
206
207
208       Paths:
209            /usr/bin/boinc, /usr/bin/boinc_client
210
211
212       boinc_initrc_exec_t
213
214       - Set files with the boinc_initrc_exec_t type, if you want  to  transi‐
215       tion an executable to the boinc_initrc_t domain.
216
217
218
219       boinc_log_t
220
221       - Set files with the boinc_log_t type, if you want to treat the data as
222       boinc log data, usually stored under the /var/log directory.
223
224
225       Paths:
226            /var/log/boinc.log.*, /var/log/boincerr.log.*
227
228
229       boinc_project_tmp_t
230
231       - Set files with the boinc_project_tmp_t type, if  you  want  to  store
232       boinc project temporary files in the /tmp directories.
233
234
235
236       boinc_project_var_lib_t
237
238       - Set files with the boinc_project_var_lib_t type, if you want to store
239       the boinc project files under the /var/lib directory.
240
241
242       Paths:
243            /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
244
245
246       boinc_tmp_t
247
248       - Set files with the boinc_tmp_t type, if you want to store boinc  tem‐
249       porary files in the /tmp directories.
250
251
252
253       boinc_tmpfs_t
254
255       -  Set  files  with  the boinc_tmpfs_t type, if you want to store boinc
256       files on a tmpfs file system.
257
258
259
260       boinc_unit_file_t
261
262       - Set files with the boinc_unit_file_t type, if you want to  treat  the
263       files as boinc unit content.
264
265
266
267       boinc_var_lib_t
268
269       -  Set  files  with  the boinc_var_lib_t type, if you want to store the
270       boinc files under the /var/lib directory.
271
272
273       Paths:
274            /var/lib/boinc(/.*)?,   /var/lib/boinc-client(/.*)?,   /etc/boinc-
275            client/global_prefs_override.xml
276
277
278       Note:  File context can be temporarily modified with the chcon command.
279       If you want to permanently change the file context you need to use  the
280       semanage fcontext command.  This will modify the SELinux labeling data‐
281       base.  You will need to use restorecon to apply the labels.
282
283

COMMANDS

285       semanage fcontext can also be used to manipulate default  file  context
286       mappings.
287
288       semanage  permissive  can  also  be used to manipulate whether or not a
289       process type is permissive.
290
291       semanage module can also be used to enable/disable/install/remove  pol‐
292       icy modules.
293
294       semanage port can also be used to manipulate the port definitions
295
296       semanage boolean can also be used to manipulate the booleans
297
298
299       system-config-selinux is a GUI tool available to customize SELinux pol‐
300       icy settings.
