NAME

6       xend_selinux - Security Enhanced Linux Policy for the xend processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the xend processes via flexible manda‐
10       tory access control.
11
12       The xend processes execute with the xend_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep xend_t
19
20
21

ENTRYPOINTS

23       The xend_t SELinux type can be entered via the xend_exec_t file type.
24
25       The default entrypoint paths for the xend_t domain are the following:
26
27       /usr/sbin/xend
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       xend policy is very flexible allowing users to setup  their  xend  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for xend:
40
41       xend_t
42
43       Note:  semanage  permissive  -a  xend_t can be used to make the process
44       type xend_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.   xend
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run xend with the tightest access possible.
53
54
55
56       If you want to allow xen to manage nfs files,  you  must  turn  on  the
57       xen_use_nfs boolean. Disabled by default.
58
59       setsebool -P xen_use_nfs 1
60
61
62
63       If  you  want  to allow xend to run blktapctrl/tapdisk. Not required if
64       using dedicated logical volumes for disk images, you must turn  on  the
65       xend_run_blktap boolean. Enabled by default.
66
67       setsebool -P xend_run_blktap 1
68
69
70
71       If  you  want  to allow xend to run qemu-dm. Not required if using par‐
72       avirt and no vfb, you must turn on the xend_run_qemu  boolean.  Enabled
73       by default.
74
75       setsebool -P xend_run_qemu 1
76
77
78
79       If  you  want  to  dontaudit all daemons scheduling requests (setsched,
80       sys_nice), you must turn on the  daemons_dontaudit_scheduling  boolean.
81       Enabled by default.
82
83       setsebool -P daemons_dontaudit_scheduling 1
84
85
86
87       If you want to allow all domains to execute in fips_mode, you must turn
88       on the fips_mode boolean. Enabled by default.
89
90       setsebool -P fips_mode 1
91
92
93
94       If you want to allow confined applications to use nscd  shared  memory,
95       you must turn on the nscd_use_shm boolean. Enabled by default.
96
97       setsebool -P nscd_use_shm 1
98
99

PORT TYPES

102       SELinux defines port types to represent TCP and UDP ports.
103
104       You  can  see  the  types associated with a port by using the following
105       command:
106
107       semanage port -l
108
109
110       Policy governs the access  confined  processes  have  to  these  ports.
111       SELinux xend policy is very flexible allowing users to setup their xend
112       processes in as secure a method as possible.
113
114       The following port types are defined for xend:
115
116
117       xen_port_t
118
119
120
121       Default Defined Ports:
122                 tcp 8002
123

MANAGED FILES

125       The SELinux process type xend_t can manage files labeled with the  fol‐
126       lowing  file  types.   The paths listed are the default paths for these
127       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

223       SELinux requires files to have an extended attribute to define the file
224       type.
225
226       You can see the context of a file using the -Z option to ls
227
228       Policy  governs  the  access  confined  processes  have to these files.
229       SELinux xend policy is very flexible allowing users to setup their xend
230       processes in as secure a method as possible.
231
232       EQUIVALENCE DIRECTORIES
233
234
235       xend  policy stores data with multiple different file context types un‐
236       der the /var/lib/xen directory.  If you would like to store the data in
237       a  different  directory  you  can use the semanage command to create an
238       equivalence mapping.  If you wanted to store this data under  the  /srv
239       directory you would execute the following command:
240
241       semanage fcontext -a -e /var/lib/xen /srv/xen
242       restorecon -R -v /srv/xen
243
244       xend  policy stores data with multiple different file context types un‐
245       der the /var/log/xen directory.  If you would like to store the data in
246       a  different  directory  you  can use the semanage command to create an
247       equivalence mapping.  If you wanted to store this data under  the  /srv
248       directory you would execute the following command:
249
250       semanage fcontext -a -e /var/log/xen /srv/xen
251       restorecon -R -v /srv/xen
252
253       xend  policy stores data with multiple different file context types un‐
254       der the /var/run/xend directory.  If you would like to store  the  data
255       in  a different directory you can use the semanage command to create an
256       equivalence mapping.  If you wanted to store this data under  the  /srv
257       directory you would execute the following command:
258
259       semanage fcontext -a -e /var/run/xend /srv/xend
260       restorecon -R -v /srv/xend
261
262       STANDARD FILE CONTEXT
263
264       SELinux  defines  the file context types for the xend, if you wanted to
265       store files with these types in a different paths, you need to  execute
266       the  semanage  command  to  specify alternate labeling and then use re‐
267       storecon to put the labels on disk.
268
269       semanage fcontext -a -t xend_exec_t '/srv/xend/content(/.*)?'
270       restorecon -R -v /srv/myxend_content
271
272       Note: SELinux often uses regular expressions  to  specify  labels  that
273       match multiple files.
274
275       The following file types are defined for xend:
276
277
278
279       xend_exec_t
280
281       - Set files with the xend_exec_t type, if you want to transition an ex‐
282       ecutable to the xend_t domain.
283
284
285
286       xend_tmp_t
287
288       - Set files with the xend_tmp_t type, if you want to store xend  tempo‐
289       rary files in the /tmp directories.
290
291
292
293       xend_var_lib_t
294
295       - Set files with the xend_var_lib_t type, if you want to store the xend
296       files under the /var/lib directory.
297
298
299       Paths:
300            /var/lib/xen(/.*)?, /var/lib/xend(/.*)?
301
302
303       xend_var_log_t
304
305       - Set files with the xend_var_log_t type, if you want to treat the data
306       as xend var log data, usually stored under the /var/log directory.
307
308
309       Paths:
310            /var/log/xen(/.*)?,     /var/log/xend.log.*,     /var/log/xend-de‐
311            bug.log.*, /var/log/xen-hotplug.log.*
312
313
314       xend_var_run_t
315
316       - Set files with the xend_var_run_t type, if you want to store the xend
317       files under the /run or /var/run directory.
318
319
320       Paths:
321            /var/run/xend(/.*)?, /var/run/xenner(/.*)?, /var/run/xend.pid
322
323
324       Note:  File context can be temporarily modified with the chcon command.
325       If you want to permanently change the file context you need to use  the
326       semanage fcontext command.  This will modify the SELinux labeling data‐
327       base.  You will need to use restorecon to apply the labels.
328
329

COMMANDS

331       semanage fcontext can also be used to manipulate default  file  context
332       mappings.
333
334       semanage  permissive  can  also  be used to manipulate whether or not a
335       process type is permissive.
336
337       semanage module can also be used to enable/disable/install/remove  pol‐
338       icy modules.
339
340       semanage port can also be used to manipulate the port definitions
341
342       semanage boolean can also be used to manipulate the booleans
343
344
345       system-config-selinux is a GUI tool available to customize SELinux pol‐
346       icy settings.
