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 qemu-ga read all non-security file types, you must
61       turn  on  the  virt_qemu_ga_read_nonsecurity_files boolean. Disabled by
62       default.
63
64       setsebool -P virt_qemu_ga_read_nonsecurity_files 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  system  to run with NIS, you must turn on the
76       nis_enabled boolean. Disabled by default.
77
78       setsebool -P nis_enabled 1
79
80
81
82       If you want to allow qemu-ga to read qemu-ga date, you must turn on the
83       virt_read_qemu_ga_data boolean. Disabled by default.
84
85       setsebool -P virt_read_qemu_ga_data 1
86
87
88
89       If  you  want to allow qemu-ga to manage qemu-ga date, you must turn on
90       the virt_rw_qemu_ga_data boolean. Disabled by default.
91
92       setsebool -P virt_rw_qemu_ga_data 1

MANAGED FILES

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

FILE CONTEXTS

187       SELinux requires files to have an extended attribute to define the file
188       type.
189
190       You can see the context of a file using the -Z option to ls
191
192       Policy governs the access  confined  processes  have  to  these  files.
193       SELinux  virt_qemu_ga  policy  is very flexible allowing users to setup
194       their virt_qemu_ga processes in as secure a method as possible.
195
196       EQUIVALENCE DIRECTORIES
197
198
199       virt_qemu_ga policy stores data with multiple  different  file  context
200       types under the /var/log/qemu-ga directory.  If you would like to store
201       the data in a different directory you can use the semanage  command  to
202       create  an equivalence mapping.  If you wanted to store this data under
203       the /srv directory you would execute the following command:
204
205       semanage fcontext -a -e /var/log/qemu-ga /srv/qemu-ga
206       restorecon -R -v /srv/qemu-ga
207
208       STANDARD FILE CONTEXT
209
210       SELinux defines the file context types for  the  virt_qemu_ga,  if  you
211       wanted  to store files with these types in a diffent paths, you need to
212       execute the semanage command to sepecify alternate  labeling  and  then
213       use restorecon to put the labels on disk.
214
215       semanage  fcontext  -a -t virt_qemu_ga_data_t '/srv/myvirt_qemu_ga_con‐
216       tent(/.*)?'
217       restorecon -R -v /srv/myvirt_qemu_ga_content
218
219       Note: SELinux often uses regular expressions  to  specify  labels  that
220       match multiple files.
221
222       The following file types are defined for virt_qemu_ga:
223
224
225
226       virt_qemu_ga_data_t
227
228       - Set files with the virt_qemu_ga_data_t type, if you want to treat the
229       files as virt qemu ga content.
230
231
232
233       virt_qemu_ga_exec_t
234
235       - Set files with the virt_qemu_ga_exec_t type, if you want  to  transi‐
236       tion an executable to the virt_qemu_ga_t domain.
237
238
239       Paths:
240            /usr/libexec/qemu-ga(/.*)?, /usr/bin/qemu-ga
241
242
243       virt_qemu_ga_log_t
244
245       -  Set files with the virt_qemu_ga_log_t type, if you want to treat the
246       data as virt qemu ga log data, usually stored under the /var/log direc‐
247       tory.
248
249
250       Paths:
251            /var/log/qemu-ga(/.*)?, /var/log/qemu-ga.log.*
252
253
254       virt_qemu_ga_tmp_t
255
256       - Set files with the virt_qemu_ga_tmp_t type, if you want to store virt
257       qemu ga temporary files in the /tmp directories.
258
259
260
261       virt_qemu_ga_unconfined_exec_t
262
263       - Set files with the virt_qemu_ga_unconfined_exec_t type, if  you  want
264       to transition an executable to the virt_qemu_ga_unconfined_t domain.
265
266
267       Paths:
268            /etc/qemu-ga/fsfreeze-hook.d(/.*)?,     /var/run/qemu-ga/fsfreeze-
269            hook.d(/.*)?, /usr/libexec/qemu-ga/fsfreeze-hook.d(/.*)?
270
271
272       virt_qemu_ga_var_run_t
273
274       - Set files with the virt_qemu_ga_var_run_t type, if you want to  store
275       the virt qemu ga files under the /run or /var/run directory.
276
277
278       Paths:
279            /var/run/qga.state, /var/run/qemu-ga.pid
280
281
282       Note:  File context can be temporarily modified with the chcon command.
283       If you want to permanently change the file context you need to use  the
284       semanage fcontext command.  This will modify the SELinux labeling data‐
285       base.  You will need to use restorecon to apply the labels.
286
287

COMMANDS

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