NAME

6       semanage_selinux - Security Enhanced Linux Policy for the semanage pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  semanage  processes  via  flexible
11       mandatory access control.
12
13       The  semanage  processes  execute with the semanage_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 semanage_t
20
21
22

ENTRYPOINTS

24       The semanage_t SELinux type can be entered via the semanage_exec_t file
25       type.
26
27       The default entrypoint paths for the semanage_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/semanage,   /usr/sbin/semodule,   /usr/libexec/selinux/seman‐
31       age_migrate_store,  /usr/share/system-config-selinux/selinux_server.py,
32       /usr/share/system-config-selinux/system-config-selinux-dbus.py
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       semanage policy is very flexible allowing users to setup their semanage
42       processes in as secure a method as possible.
43
44       The following process types are defined for semanage:
45
46       semanage_t
47
48       Note: semanage permissive -a semanage_t can be used to make the process
49       type  semanage_t permissive. SELinux does not deny access to permissive
50       process types, but the AVC (SELinux denials) messages are still  gener‐
51       ated.
52
53

BOOLEANS

55       SELinux  policy is customizable based on least access required.  seman‐
56       age policy is extremely flexible and has several  booleans  that  allow
57       you  to manipulate the policy and run semanage with the tightest access
58       possible.
59
60
61
62       If you want to allow users to resolve user passwd entries directly from
63       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
64       gin_nsswitch_use_ldap boolean. Disabled by default.
65
66       setsebool -P authlogin_nsswitch_use_ldap 1
67
68
69
70       If you want to deny user domains applications to map a memory region as
71       both  executable  and  writable,  this  is dangerous and the executable
72       should be reported in bugzilla, you must turn on the deny_execmem bool‐
73       ean. Enabled by default.
74
75       setsebool -P deny_execmem 1
76
77
78
79       If you want to allow all domains to execute in fips_mode, you must turn
80       on the fips_mode boolean. Enabled by default.
81
82       setsebool -P fips_mode 1
83
84
85
86       If you want to allow confined applications to run  with  kerberos,  you
87       must turn on the kerberos_enabled boolean. Enabled by default.
88
89       setsebool -P kerberos_enabled 1
90
91
92
93       If  you  want  to control the ability to mmap a low area of the address
94       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
95       the mmap_low_allowed boolean. Disabled by default.
96
97       setsebool -P mmap_low_allowed 1
98
99
100
101       If  you  want  to  allow  system  to run with NIS, you must turn on the
102       nis_enabled boolean. Disabled by default.
103
104       setsebool -P nis_enabled 1
105
106
107
108       If you want to allow confined applications to use nscd  shared  memory,
109       you must turn on the nscd_use_shm boolean. Disabled by default.
110
111       setsebool -P nscd_use_shm 1
112
113
114
115       If  you  want  to  disable  kernel module loading, you must turn on the
116       secure_mode_insmod boolean. Enabled by default.
117
118       setsebool -P secure_mode_insmod 1
119
120
121
122       If you want to allow unconfined executables to make their  heap  memory
123       executable.   Doing  this  is  a  really bad idea. Probably indicates a
124       badly coded executable, but could indicate an attack.  This  executable
125       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
126       uxuser_execheap boolean. Disabled by default.
127
128       setsebool -P selinuxuser_execheap 1
129
130
131
132       If you want to allow unconfined executables to make  their  stack  exe‐
133       cutable.   This  should  never, ever be necessary. Probably indicates a
134       badly coded executable, but could indicate an attack.  This  executable
135       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
136       stack boolean. Enabled by default.
137
138       setsebool -P selinuxuser_execstack 1
139
140
141

MANAGED FILES

143       The SELinux process type semanage_t can manage files labeled  with  the
144       following file types.  The paths listed are the default paths for these
145       file types.  Note the processes UID still need to have DAC permissions.
146
147       file_type
148
149            all files on the system
150
151

FILE CONTEXTS

153       SELinux requires files to have an extended attribute to define the file
154       type.
155
156       You can see the context of a file using the -Z option to ls
157
158       Policy  governs  the  access  confined  processes  have to these files.
159       SELinux semanage policy is very flexible allowing users to setup  their
160       semanage processes in as secure a method as possible.
161
162       EQUIVALENCE DIRECTORIES
163
164
165       semanage  policy stores data with multiple different file context types
166       under the /var/lib/selinux directory.  If you would like to  store  the
167       data  in a different directory you can use the semanage command to cre‐
168       ate an equivalence mapping.  If you wanted to store this data under the
169       /srv dirctory you would execute the following command:
170
171       semanage fcontext -a -e /var/lib/selinux /srv/selinux
172       restorecon -R -v /srv/selinux
173
174       STANDARD FILE CONTEXT
175
176       SELinux  defines the file context types for the semanage, if you wanted
177       to store files with these types in a diffent paths, you need to execute
178       the  semanage  command  to  sepecify  alternate  labeling  and then use
179       restorecon to put the labels on disk.
180
181       semanage fcontext  -a  -t  semanage_trans_lock_t  '/srv/mysemanage_con‐
182       tent(/.*)?'
183       restorecon -R -v /srv/mysemanage_content
184
185       Note:  SELinux  often  uses  regular expressions to specify labels that
186       match multiple files.
187
188       The following file types are defined for semanage:
189
190
191
192       semanage_exec_t
193
194       - Set files with the semanage_exec_t type, if you want to transition an
195       executable to the semanage_t domain.
196
197
198       Paths:
199            /usr/sbin/semanage,  /usr/sbin/semodule, /usr/libexec/selinux/sem‐
200            anage_migrate_store,                     /usr/share/system-config-
201            selinux/selinux_server.py,   /usr/share/system-config-selinux/sys‐
202            tem-config-selinux-dbus.py
203
204
205       semanage_read_lock_t
206
207       - Set files with the semanage_read_lock_t type, if you  want  to  treat
208       the files as semanage read lock data, stored under the /var/lock direc‐
209       tory
210
211
212       Paths:
213            /etc/selinux/([^/]*/)?modules/semanage.read.LOCK,
214            /var/lib/selinux/[^/]+/semanage.read.LOCK
215
216
217       semanage_store_t
218
219       -  Set  files  with the semanage_store_t type, if you want to treat the
220       files as semanage store data.
221
222
223       Paths:
224            /etc/selinux/([^/]*/)?policy(/.*)?, /etc/selinux/(minimum|mls|tar‐
225            geted)/active(/.*)?,                    /etc/selinux/([^/]*/)?mod‐
226            ules/(active|tmp|previous)(/.*)?,          /var/lib/selinux(/.*)?,
227            /etc/share/selinux/mls(/.*)?, /etc/share/selinux/targeted(/.*)?
228
229
230       semanage_tmp_t
231
232       - Set files with the semanage_tmp_t type, if you want to store semanage
233       temporary files in the /tmp directories.
234
235
236
237       semanage_trans_lock_t
238
239       - Set files with the semanage_trans_lock_t type, if you want  to  treat
240       the  files  as  semanage  trans  lock  data, stored under the /var/lock
241       directory
242
243
244       Paths:
245            /etc/selinux/([^/]*/)?modules/semanage.trans.LOCK,
246            /var/lib/selinux/[^/]+/semanage.trans.LOCK
247
248
249       Note:  File context can be temporarily modified with the chcon command.
250       If you want to permanently change the file context you need to use  the
251       semanage fcontext command.  This will modify the SELinux labeling data‐
252       base.  You will need to use restorecon to apply the labels.
253
254

COMMANDS

256       semanage fcontext can also be used to manipulate default  file  context
257       mappings.
258
259       semanage  permissive  can  also  be used to manipulate whether or not a
260       process type is permissive.
261
262       semanage module can also be used to enable/disable/install/remove  pol‐
263       icy modules.
264
265       semanage boolean can also be used to manipulate the booleans
266
267
268       system-config-selinux is a GUI tool available to customize SELinux pol‐
269       icy settings.
