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.
46
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. Enabled 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.
80
81       cifs_t
82
83
84       nfs_t
85
86
87       uml_rw_t
88
89            /home/[^/]+/.uml(/.*)?

91

FILE CONTEXTS

93       SELinux requires files to have an extended attribute to define the file
94       type.
95
96       You can see the context of a file using the -Z option to ls
97
98       Policy  governs  the  access  confined  processes  have to these files.
99       SELinux uml policy is very flexible allowing users to setup  their  uml
100       processes in as secure a method as possible.
101
102       STANDARD FILE CONTEXT
103
104       SELinux  defines  the  file context types for the uml, if you wanted to
105       store files with these types in a diffent paths, you  need  to  execute
106       the  semanage  command  to  sepecify  alternate  labeling  and then use
107       restorecon to put the labels on disk.
108
109       semanage fcontext -a -t uml_switch_var_run_t '/srv/myuml_content(/.*)?'
110       restorecon -R -v /srv/myuml_content
111
112       Note: SELinux often uses regular expressions  to  specify  labels  that
113       match multiple files.
114
115       The following file types are defined for uml:
116
117
118
119       uml_exec_t
120
121       - Set files with the uml_exec_t type, if you want to transition an exe‐
122       cutable to the uml_t domain.
123
124
125
126       uml_ro_t
127
128       - Set files with the uml_ro_t type, if you want to treat the  files  as
129       uml read/only content.
130
131
132
133       uml_rw_t
134
135       -  Set  files with the uml_rw_t type, if you want to treat the files as
136       uml read/write content.
137
138
139
140       uml_switch_exec_t
141
142       - Set files with the uml_switch_exec_t type, if you want to  transition
143       an executable to the uml_switch_t domain.
144
145
146
147       uml_switch_var_run_t
148
149       -  Set  files  with the uml_switch_var_run_t type, if you want to store
150       the uml switch files under the /run or /var/run directory.
151
152
153
154       uml_tmp_t
155
156       - Set files with the uml_tmp_t type, if you want to store uml temporary
157       files in the /tmp directories.
158
159
160
161       uml_tmpfs_t
162
163       -  Set  files with the uml_tmpfs_t type, if you want to store uml files
164       on a tmpfs file system.
165
166
167
168       Note: File context can be temporarily modified with the chcon  command.
169       If  you want to permanently change the file context you need to use the
170       semanage fcontext command.  This will modify the SELinux labeling data‐
171       base.  You will need to use restorecon to apply the labels.
172
173

COMMANDS

175       semanage  fcontext  can also be used to manipulate default file context
176       mappings.
177
178       semanage permissive can also be used to manipulate  whether  or  not  a
179       process type is permissive.
180
181       semanage  module can also be used to enable/disable/install/remove pol‐
182       icy modules.
183
184       semanage boolean can also be used to manipulate the booleans
185
186
187       system-config-selinux is a GUI tool available to customize SELinux pol‐
188       icy settings.
