NAME

6       virt_qemu_ga_selinux   -   Security   Enhanced  Linux  Policy  for  the
7       virt_qemu_ga processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the virt_qemu_ga processes via flexible
11       mandatory access control.
12
13       The  virt_qemu_ga  processes  execute  with  the virt_qemu_ga_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep virt_qemu_ga_t
20
21
22

ENTRYPOINTS

24       The    virt_qemu_ga_t   SELinux   type   can   be   entered   via   the
25       virt_qemu_ga_exec_t file type.
26
27       The default entrypoint paths for the virt_qemu_ga_t domain are the fol‐
28       lowing:
29
30       /usr/libexec/qemu-ga(/.*)?, /usr/bin/qemu-ga
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       virt_qemu_ga  policy  is  very  flexible  allowing users to setup their
40       virt_qemu_ga processes in as secure a method as possible.
41
42       The following process types are defined for virt_qemu_ga:
43
44       virt_qemu_ga_t, virt_qemu_ga_unconfined_t
45
46       Note: semanage permissive -a virt_qemu_ga_t can be  used  to  make  the
47       process type virt_qemu_ga_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       virt_qemu_ga policy is extremely flexible and has several booleans that
55       allow you to manipulate the policy and run virt_qemu_ga with the tight‐
56       est access possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Disabled by default.
91
92       setsebool -P nscd_use_shm 1
93
94
95
96       If you want to allow qemu-ga to read qemu-ga date, you must turn on the
97       virt_read_qemu_ga_data boolean. Disabled by default.
98
99       setsebool -P virt_read_qemu_ga_data 1
100
101
102
103       If  you  want to allow qemu-ga to manage qemu-ga date, you must turn on
104       the virt_rw_qemu_ga_data boolean. Disabled by default.
105
106       setsebool -P virt_rw_qemu_ga_data 1

MANAGED FILES

111       The SELinux process type virt_qemu_ga_t can manage files  labeled  with
112       the  following  file types.  The paths listed are the default paths for
113       these file types.  Note the processes UID still need to have  DAC  per‐
114       missions.

FILE CONTEXTS

200       SELinux requires files to have an extended attribute to define the file
201       type.
202
203       You can see the context of a file using the -Z option to ls
204
205       Policy governs the access  confined  processes  have  to  these  files.
206       SELinux  virt_qemu_ga  policy  is very flexible allowing users to setup
207       their virt_qemu_ga processes in as secure a method as possible.
208
209       EQUIVALENCE DIRECTORIES
210
211
212       virt_qemu_ga policy stores data with multiple  different  file  context
213       types under the /var/log/qemu-ga directory.  If you would like to store
214       the data in a different directory you can use the semanage  command  to
215       create  an equivalence mapping.  If you wanted to store this data under
216       the /srv dirctory you would execute the following command:
217
218       semanage fcontext -a -e /var/log/qemu-ga /srv/qemu-ga
219       restorecon -R -v /srv/qemu-ga
220
221       STANDARD FILE CONTEXT
222
223       SELinux defines the file context types for  the  virt_qemu_ga,  if  you
224       wanted  to store files with these types in a diffent paths, you need to
225       execute the semanage command to sepecify alternate  labeling  and  then
226       use restorecon to put the labels on disk.
227
228       semanage  fcontext  -a -t virt_qemu_ga_data_t '/srv/myvirt_qemu_ga_con‐
229       tent(/.*)?'
230       restorecon -R -v /srv/myvirt_qemu_ga_content
231
232       Note: SELinux often uses regular expressions  to  specify  labels  that
233       match multiple files.
234
235       The following file types are defined for virt_qemu_ga:
236
237
238
239       virt_qemu_ga_data_t
240
241       - Set files with the virt_qemu_ga_data_t type, if you want to treat the
242       files as virt qemu ga content.
243
244
245
246       virt_qemu_ga_exec_t
247
248       - Set files with the virt_qemu_ga_exec_t type, if you want  to  transi‐
249       tion an executable to the virt_qemu_ga_t domain.
250
251
252       Paths:
253            /usr/libexec/qemu-ga(/.*)?, /usr/bin/qemu-ga
254
255
256       virt_qemu_ga_log_t
257
258       -  Set files with the virt_qemu_ga_log_t type, if you want to treat the
259       data as virt qemu ga log data, usually stored under the /var/log direc‐
260       tory.
261
262
263       Paths:
264            /var/log/qemu-ga(/.*)?, /var/log/qemu-ga.log.*
265
266
267       virt_qemu_ga_tmp_t
268
269       - Set files with the virt_qemu_ga_tmp_t type, if you want to store virt
270       qemu ga temporary files in the /tmp directories.
271
272
273
274       virt_qemu_ga_unconfined_exec_t
275
276       - Set files with the virt_qemu_ga_unconfined_exec_t type, if  you  want
277       to transition an executable to the virt_qemu_ga_unconfined_t domain.
278
279
280       Paths:
281            /etc/qemu-ga/fsfreeze-hook.d(/.*)?,     /var/run/qemu-ga/fsfreeze-
282            hook.d(/.*)?, /usr/libexec/qemu-ga/fsfreeze-hook.d(/.*)?
283
284
285       virt_qemu_ga_var_run_t
286
287       - Set files with the virt_qemu_ga_var_run_t type, if you want to  store
288       the virt qemu ga files under the /run or /var/run directory.
289
290
291       Paths:
292            /var/run/qga.state, /var/run/qemu-ga.pid
293
294
295       Note:  File context can be temporarily modified with the chcon command.
296       If you want to permanently change the file context you need to use  the
297       semanage fcontext command.  This will modify the SELinux labeling data‐
298       base.  You will need to use restorecon to apply the labels.
299
300

COMMANDS

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