NAME

6       virt_qemu_ga_unconfined_selinux  -  Security  Enhanced Linux Policy for
7       the virt_qemu_ga_unconfined processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  virt_qemu_ga_unconfined_t  SELinux  type  can  be  entered via the
25       virt_qemu_ga_unconfined_exec_t file type.
26
27       The default entrypoint paths for the  virt_qemu_ga_unconfined_t  domain
28       are the following:
29
30       /etc/qemu-ga/fsfreeze-hook.d(/.*)?,          /var/run/qemu-ga/fsfreeze-
31       hook.d(/.*)?, /usr/libexec/qemu-ga/fsfreeze-hook.d(/.*)?
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       virt_qemu_ga_unconfined policy is very flexible allowing users to setup
41       their virt_qemu_ga_unconfined processes in as secure a method as possi‐
42       ble.
43
44       The following process types are defined for virt_qemu_ga_unconfined:
45
46       virt_qemu_ga_unconfined_t
47
48       Note: semanage permissive -a virt_qemu_ga_unconfined_t can be  used  to
49       make  the  process  type  virt_qemu_ga_unconfined_t permissive. SELinux
50       does not deny access to permissive process types, but the AVC  (SELinux
51       denials) messages are still generated.
52
53

BOOLEANS

55       SELinux   policy  is  customizable  based  on  least  access  required.
56       virt_qemu_ga_unconfined policy is extremely flexible  and  has  several
57       booleans   that   allow   you   to   manipulate   the  policy  and  run
58       virt_qemu_ga_unconfined with the tightest access possible.
59
60
61
62       If you want to deny user domains applications to map a memory region as
63       both  executable  and  writable,  this  is dangerous and the executable
64       should be reported in bugzilla, you must turn on the deny_execmem bool‐
65       ean. Enabled by default.
66
67       setsebool -P deny_execmem 1
68
69
70
71       If you want to allow all domains to execute in fips_mode, you must turn
72       on the fips_mode boolean. Enabled by default.
73
74       setsebool -P fips_mode 1
75
76
77
78       If you want to control the ability to mmap a low area  of  the  address
79       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
80       the mmap_low_allowed boolean. Disabled by default.
81
82       setsebool -P mmap_low_allowed 1
83
84
85
86       If you want to disable kernel module loading,  you  must  turn  on  the
87       secure_mode_insmod boolean. Enabled by default.
88
89       setsebool -P secure_mode_insmod 1
90
91
92
93       If  you  want to allow unconfined executables to make their heap memory
94       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
95       badly  coded  executable, but could indicate an attack. This executable
96       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
97       uxuser_execheap boolean. Disabled by default.
98
99       setsebool -P selinuxuser_execheap 1
100
101
102
103       If  you  want  to allow unconfined executables to make their stack exe‐
104       cutable.  This should never, ever be necessary.  Probably  indicates  a
105       badly  coded  executable, but could indicate an attack. This executable
106       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
107       stack boolean. Disabled by default.
108
109       setsebool -P selinuxuser_execstack 1

MANAGED FILES

114       The  SELinux  process  type  virt_qemu_ga_unconfined_t can manage files
115       labeled with the following  file  types.   The  paths  listed  are  the
116       default  paths for these file types.  Note the processes UID still need
117       to have DAC permissions.
118
119       file_type
120
121            all files on the system
122
123

FILE CONTEXTS

125       SELinux requires files to have an extended attribute to define the file
126       type.
127
128       You can see the context of a file using the -Z option to ls
129
130       Policy  governs  the  access  confined  processes  have to these files.
131       SELinux virt_qemu_ga_unconfined policy is very flexible allowing  users
132       to  setup their virt_qemu_ga_unconfined processes in as secure a method
133       as possible.
134
135       The following file types are defined for virt_qemu_ga_unconfined:
136
137
138
139       virt_qemu_ga_unconfined_exec_t
140
141       - Set files with the virt_qemu_ga_unconfined_exec_t type, if  you  want
142       to transition an executable to the virt_qemu_ga_unconfined_t domain.
143
144
145       Paths:
146            /etc/qemu-ga/fsfreeze-hook.d(/.*)?,     /var/run/qemu-ga/fsfreeze-
147            hook.d(/.*)?, /usr/libexec/qemu-ga/fsfreeze-hook.d(/.*)?
148
149
150       Note: File context can be temporarily modified with the chcon  command.
151       If  you want to permanently change the file context you need to use the
152       semanage fcontext command.  This will modify the SELinux labeling data‐
153       base.  You will need to use restorecon to apply the labels.
154
155

COMMANDS

157       semanage  fcontext  can also be used to manipulate default file context
158       mappings.
159
160       semanage permissive can also be used to manipulate  whether  or  not  a
161       process type is permissive.
162
163       semanage  module can also be used to enable/disable/install/remove pol‐
164       icy modules.
165
166       semanage boolean can also be used to manipulate the booleans
167
168
169       system-config-selinux is a GUI tool available to customize SELinux pol‐
170       icy settings.
