NAME

6       uml_selinux - Security Enhanced Linux Policy for the uml processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the uml processes via flexible manda‐
10       tory access control.
11
12       The uml processes execute with the uml_t SELinux type. You can check if
13       you  have  these processes running by executing the ps command with the
14       -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep uml_t

21

ENTRYPOINTS

23       The uml_t SELinux type can be entered via the uml_exec_t file type.
24
25       The default entrypoint paths for the uml_t domain are the following:

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       uml policy is very flexible allowing users to setup their uml processes
37       in as secure a method as possible.
38
39       The following process types are defined for uml:
40
41       uml_t, uml_switch_t
42
43       Note: semanage permissive -a uml_t can be used to make the process type
44       uml_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.

47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  uml
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run uml with the tightest access possible.
52
53
54
55       If you want to allow all domains to execute in fips_mode, you must turn
56       on the fips_mode boolean. Enabled by default.
57
58       setsebool -P fips_mode 1
59
60
61
62       If you want to support NFS home  directories,  you  must  turn  on  the
63       use_nfs_home_dirs boolean. Disabled by default.
64
65       setsebool -P use_nfs_home_dirs 1
66
67
68
69       If  you  want  to  support SAMBA home directories, you must turn on the
70       use_samba_home_dirs boolean. Disabled by default.
71
72       setsebool -P use_samba_home_dirs 1

MANAGED FILES

77       The SELinux process type uml_t can manage files labeled with  the  fol‐
78       lowing  file  types.   The paths listed are the default paths for these
79       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

113       SELinux requires files to have an extended attribute to define the file
114       type.
115
116       You can see the context of a file using the -Z option to ls
117
118       Policy  governs  the  access  confined  processes  have to these files.
119       SELinux uml policy is very flexible allowing users to setup  their  uml
120       processes in as secure a method as possible.
121
122       STANDARD FILE CONTEXT
123
124       SELinux  defines  the  file context types for the uml, if you wanted to
125       store files with these types in a diffent paths, you  need  to  execute
126       the  semanage  command  to  specify alternate labeling and then use re‐
127       storecon to put the labels on disk.
128
129       semanage fcontext -a -t uml_switch_var_run_t '/srv/myuml_content(/.*)?'
130       restorecon -R -v /srv/myuml_content
131
132       Note: SELinux often uses regular expressions  to  specify  labels  that
133       match multiple files.
134
135       The following file types are defined for uml:
136
137
138
139       uml_exec_t
140
141       - Set files with the uml_exec_t type, if you want to transition an exe‐
142       cutable to the uml_t domain.
143
144
145
146       uml_ro_t
147
148       - Set files with the uml_ro_t type, if you want to treat the  files  as
149       uml read/only content.
150
151
152
153       uml_rw_t
154
155       -  Set  files with the uml_rw_t type, if you want to treat the files as
156       uml read/write content.
157
158
159
160       uml_switch_exec_t
161
162       - Set files with the uml_switch_exec_t type, if you want to  transition
163       an executable to the uml_switch_t domain.
164
165
166
167       uml_switch_var_run_t
168
169       -  Set  files  with the uml_switch_var_run_t type, if you want to store
170       the uml switch files under the /run or /var/run directory.
171
172
173
174       uml_tmp_t
175
176       - Set files with the uml_tmp_t type, if you want to store uml temporary
177       files in the /tmp directories.
178
179
180
181       uml_tmpfs_t
182
183       -  Set  files with the uml_tmpfs_t type, if you want to store uml files
184       on a tmpfs file system.
185
186
187
188       Note: File context can be temporarily modified with the chcon  command.
189       If  you want to permanently change the file context you need to use the
190       semanage fcontext command.  This will modify the SELinux labeling data‐
191       base.  You will need to use restorecon to apply the labels.
192
193

COMMANDS

195       semanage  fcontext  can also be used to manipulate default file context
196       mappings.
197
198       semanage permissive can also be used to manipulate  whether  or  not  a
199       process type is permissive.
200
201       semanage  module can also be used to enable/disable/install/remove pol‐
202       icy modules.
203
204       semanage boolean can also be used to manipulate the booleans
205
206
207       system-config-selinux is a GUI tool available to customize SELinux pol‐
208       icy settings.
