NAME

6       virtd_lxc_selinux  -  Security  Enhanced Linux Policy for the virtd_lxc
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the virtd_lxc  processes  via  flexible
11       mandatory access control.
12
13       The  virtd_lxc processes execute with the virtd_lxc_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 virtd_lxc_t
20

22

ENTRYPOINTS

24       The  virtd_lxc_t  SELinux type can be entered via the virtd_lxc_exec_t,
25       exec_type, mountpoint file types.
26
27       The default entrypoint paths for the virtd_lxc_t domain are the follow‐
28       ing:
29
30       /usr/libexec/libvirt_lxc
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       virtd_lxc  policy  is  very  flexible  allowing  users  to  setup their
40       virtd_lxc processes in as secure a method as possible.
41
42       The following process types are defined for virtd_lxc:
43
44       virtd_lxc_t
45
46       Note: semanage permissive -a  virtd_lxc_t  can  be  used  to  make  the
47       process  type  virtd_lxc_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       virtd_lxc policy is extremely flexible and has  several  booleans  that
55       allow  you to manipulate the policy and run virtd_lxc with the tightest
56       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 deny user domains applications to map a memory region as
69       both  executable  and  writable,  this  is dangerous and the executable
70       should be reported in bugzilla, you must turn on the deny_execmem bool‐
71       ean. Enabled by default.
72
73       setsebool -P deny_execmem 1
74
75
76
77       If you want to allow all domains to execute in fips_mode, you must turn
78       on the fips_mode boolean. Enabled by default.
79
80       setsebool -P fips_mode 1
81
82
83
84       If you want to allow confined applications to run  with  kerberos,  you
85       must turn on the kerberos_enabled boolean. Enabled by default.
86
87       setsebool -P kerberos_enabled 1
88
89
90
91       If  you  want  to control the ability to mmap a low area of the address
92       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
93       the mmap_low_allowed boolean. Disabled by default.
94
95       setsebool -P mmap_low_allowed 1
96
97
98
99       If  you  want  to  allow  system  to run with NIS, you must turn on the
100       nis_enabled boolean. Disabled by default.
101
102       setsebool -P nis_enabled 1
103
104
105
106       If you want to allow confined applications to use nscd  shared  memory,
107       you must turn on the nscd_use_shm boolean. Enabled by default.
108
109       setsebool -P nscd_use_shm 1
110
111
112
113       If  you  want  to  disable  kernel module loading, you must turn on the
114       secure_mode_insmod boolean. Enabled by default.
115
116       setsebool -P secure_mode_insmod 1
117
118
119
120       If you want to allow unconfined executables to make their  heap  memory
121       executable.   Doing  this  is  a  really bad idea. Probably indicates a
122       badly coded executable, but could indicate an attack.  This  executable
123       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
124       uxuser_execheap boolean. Disabled by default.
125
126       setsebool -P selinuxuser_execheap 1
127
128
129
130       If you want to allow unconfined executables to make  their  stack  exe‐
131       cutable.   This  should  never, ever be necessary. Probably indicates a
132       badly coded executable, but could indicate an attack.  This  executable
133       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
134       stack boolean. Enabled by default.
135
136       setsebool -P selinuxuser_execstack 1
137
138
139
140       If you want to allow virtual processes to run as userdomains, you  must
141       turn on the virt_transition_userdomain boolean. Disabled by default.
142
143       setsebool -P virt_transition_userdomain 1
144
145
146

MANAGED FILES

148       The  SELinux process type virtd_lxc_t can manage files labeled with the
149       following file types.  The paths listed are the default paths for these
150       file types.  Note the processes UID still need to have DAC permissions.
151
152       file_type
153
154            all files on the system
155
156

FILE CONTEXTS

158       SELinux requires files to have an extended attribute to define the file
159       type.
160
161       You can see the context of a file using the -Z option to ls
162
163       Policy governs the access  confined  processes  have  to  these  files.
164       SELinux virtd_lxc policy is very flexible allowing users to setup their
165       virtd_lxc processes in as secure a method as possible.
166
167       The following file types are defined for virtd_lxc:
168
169
170
171       virtd_lxc_exec_t
172
173       - Set files with the virtd_lxc_exec_t type, if you want  to  transition
174       an executable to the virtd_lxc_t domain.
175
176
177
178       Note:  File context can be temporarily modified with the chcon command.
179       If you want to permanently change the file context you need to use  the
180       semanage fcontext command.  This will modify the SELinux labeling data‐
181       base.  You will need to use restorecon to apply the labels.
182
183

COMMANDS

185       semanage fcontext can also be used to manipulate default  file  context
186       mappings.
187
188       semanage  permissive  can  also  be used to manipulate whether or not a
189       process type is permissive.
190
191       semanage module can also be used to enable/disable/install/remove  pol‐
192       icy modules.
193
194       semanage boolean can also be used to manipulate the booleans
195
196
197       system-config-selinux is a GUI tool available to customize SELinux pol‐
198       icy settings.
