NAME

6       virt_qmf_selinux - Security Enhanced Linux Policy for the virt_qmf pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The   virt_qmf_t  SELinux  type  can  be  entered  via  the  file_type,
25       virt_qmf_exec_t,     unlabeled_t,      proc_type,      filesystem_type,
26       mtrr_device_t, sysctl_type file types.
27
28       The  default entrypoint paths for the virt_qmf_t domain are the follow‐
29       ing:
30
31       all files on the system, /usr/sbin/libvirt-qmf, /dev/cpu/mtrr
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_qmf policy is very flexible allowing users to setup their virt_qmf
41       processes in as secure a method as possible.
42
43       The following process types are defined for virt_qmf:
44
45       virt_qmf_t
46
47       Note: semanage permissive -a virt_qmf_t can be used to make the process
48       type virt_qmf_t permissive. SELinux does not deny access to  permissive
49       process  types, but the AVC (SELinux denials) messages are still gener‐
50       ated.
51
52

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       virt_qmf  policy  is  extremely  flexible and has several booleans that
56       allow you to manipulate the policy and run virt_qmf with  the  tightest
57       access possible.

60
61       If you want to allow all daemons to write corefiles to /, you must turn
62       on the allow_daemons_dump_core boolean. Disabled by default.

64       setsebool -P allow_daemons_dump_core 1
65
66
67
68       If you want to allow all daemons to use tcp wrappers, you must turn  on
69       the allow_daemons_use_tcp_wrapper boolean. Disabled by default.

87
88
89
90       If you want to allow unconfined executables to make their  heap  memory
91       executable.   Doing  this  is  a  really bad idea. Probably indicates a
92       badly coded executable, but could indicate an attack.  This  executable
93       should  be  reported  in  bugzilla, you must turn on the allow_execheap
94       boolean. Disabled by default.
95
96       setsebool -P allow_execheap 1
97
98
99
100       If you want to allow unconfined executables to map a memory  region  as
101       both  executable  and  writable,  this  is dangerous and the executable
102       should be reported in bugzilla), you must  turn  on  the  allow_execmem
103       boolean. Enabled by default.
104
105       setsebool -P allow_execmem 1

110       requiring text relocation that are not  labeled  textrel_shlib_t),  you
111       must turn on the allow_execmod boolean. Enabled by default.
112
113       setsebool -P allow_execmod 1
114
115
116
117       If  you  want  to allow unconfined executables to make their stack exe‐
118       cutable.  This should never, ever be necessary.  Probably  indicates  a
119       badly  coded  executable, but could indicate an attack. This executable
120       should be reported in bugzilla), you must turn on  the  allow_execstack
121       boolean. Enabled by default.
122
123       setsebool -P allow_execstack 1
124

143       default.
144
145       setsebool -P domain_kernel_load_modules 1
146
147
148
149       If you want to allow all domains to execute in fips_mode, you must turn
150       on the fips_mode boolean. Enabled by default.
151
152       setsebool -P fips_mode 1
153
154

177       If  you want to boolean to determine whether the system permits loading
178       policy, setting enforcing mode, and changing boolean values.  Set  this
179       to  true  and  you  have to reboot to set it back, you must turn on the
180       secure_mode_policyload boolean. Disabled by default.
181
182       setsebool -P secure_mode_policyload 1
183

MANAGED FILES

194       The  SELinux  process type virt_qmf_t can manage files labeled with the
195       following file types.  The paths listed are the default paths for these
196       file types.  Note the processes UID still need to have DAC permissions.
197
198       file_type
199
200            all files on the system
201
202

FILE CONTEXTS

204       SELinux requires files to have an extended attribute to define the file
205       type.
206
207       You can see the context of a file using the -Z option to ls
208
209       Policy governs the access  confined  processes  have  to  these  files.
210       SELinux  virt_qmf policy is very flexible allowing users to setup their
211       virt_qmf processes in as secure a method as possible.
212
213       The following file types are defined for virt_qmf:
214
215
216
217       virt_qmf_exec_t
218
219       - Set files with the virt_qmf_exec_t type, if you want to transition an
220       executable to the virt_qmf_t domain.
221
222
223
224       Note:  File context can be temporarily modified with the chcon command.
225       If you want to permanently change the file context you need to use  the
226       semanage fcontext command.  This will modify the SELinux labeling data‐
227       base.  You will need to use restorecon to apply the labels.
228
229

COMMANDS

231       semanage fcontext can also be used to manipulate default  file  context
232       mappings.
233
234       semanage  permissive  can  also  be used to manipulate whether or not a
235       process type is permissive.
236
237       semanage module can also be used to enable/disable/install/remove  pol‐
238       icy modules.
239
240       semanage boolean can also be used to manipulate the booleans
241
242
243       system-config-selinux is a GUI tool available to customize SELinux pol‐
244       icy settings.
