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 virt_qemu_ga_un‐
14       confined_t SELinux type. You can check if you have these processes run‐
15       ning by executing the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep virt_qemu_ga_unconfined_t
20

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 control the ability to mmap a low area of the address
72       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
73       the mmap_low_allowed boolean. Disabled by default.
74
75       setsebool -P mmap_low_allowed 1
76
77
78
79       If  you want to disable kernel module loading, you must turn on the se‐
80       cure_mode_insmod boolean. Enabled by default.
81
82       setsebool -P secure_mode_insmod 1
83
84
85
86       If you want to allow unconfined executables to make their  heap  memory
87       executable.   Doing  this  is  a  really bad idea. Probably indicates a
88       badly coded executable, but could indicate an attack.  This  executable
89       should  be  reported  in bugzilla, you must turn on the selinuxuser_ex‐
90       echeap boolean. Disabled by default.
91
92       setsebool -P selinuxuser_execheap 1
93
94
95
96       If you want to allow unconfined executables to make  their  stack  exe‐
97       cutable.   This  should  never, ever be necessary. Probably indicates a
98       badly coded executable, but could indicate an attack.  This  executable
99       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
100       stack boolean. Enabled by default.
101
102       setsebool -P selinuxuser_execstack 1

MANAGED FILES

107       The SELinux process type virt_qemu_ga_unconfined_t can manage files la‐
108       beled  with the following file types.  The paths listed are the default
109       paths for these file types.  Note the processes UID still need to  have
110       DAC permissions.
111
112       file_type
113
114            all files on the system
115
116

FILE CONTEXTS

118       SELinux requires files to have an extended attribute to define the file
119       type.
120
121       You can see the context of a file using the -Z option to ls
122
123       Policy governs the access  confined  processes  have  to  these  files.
124       SELinux  virt_qemu_ga_unconfined policy is very flexible allowing users
125       to setup their virt_qemu_ga_unconfined processes in as secure a  method
126       as possible.
127
128       The following file types are defined for virt_qemu_ga_unconfined:
129
130
131
132       virt_qemu_ga_unconfined_exec_t
133
134       -  Set  files with the virt_qemu_ga_unconfined_exec_t type, if you want
135       to transition an executable to the virt_qemu_ga_unconfined_t domain.
136
137
138       Paths:
139            /etc/qemu-ga/fsfreeze-hook.d(/.*)?,     /var/run/qemu-ga/fsfreeze-
140            hook.d(/.*)?, /usr/libexec/qemu-ga/fsfreeze-hook.d(/.*)?
141
142
143       Note:  File context can be temporarily modified with the chcon command.
144       If you want to permanently change the file context you need to use  the
145       semanage fcontext command.  This will modify the SELinux labeling data‐
146       base.  You will need to use restorecon to apply the labels.
147
148

COMMANDS

150       semanage fcontext can also be used to manipulate default  file  context
151       mappings.
152
153       semanage  permissive  can  also  be used to manipulate whether or not a
154       process type is permissive.
155
156       semanage module can also be used to enable/disable/install/remove  pol‐
157       icy modules.
158
159       semanage boolean can also be used to manipulate the booleans
160
161
162       system-config-selinux is a GUI tool available to customize SELinux pol‐
163       icy settings.
