NAME

SYNOPSIS

10       semodule [option]... MODE...
11

DESCRIPTION

13       semodule  is  the tool used to manage SELinux policy modules, including
14       installing, upgrading, listing and removing modules.  semodule may also
15       be  used  to  force a rebuild of policy from the module store and/or to
16       force a reload of policy without performing any other transaction.  se‐
17       module  acts  on  module packages created by semodule_package.  Conven‐
18       tionally, these files have a .pp suffix (policy package), although this
19       is not mandated in any way.
20
21

MODES

23       -R, --reload
24              force a reload of policy
25
26       -B, --build
27              force a rebuild of policy (also reloads unless -n is used)
28
29       --rebuild-if-modules-changed
30              Force  a  rebuild of the policy if any changes to module content
31              are detected (by comparing with checksum from the last  transac‐
32              tion).   One  can  use  this  instead  of  -B to ensure that any
33              changes to the module store done by an  external  tool  (e.g.  a
34              package  manager)  are applied, while automatically skipping the
35              rebuild if there are no new changes.
36
37       -D, --disable_dontaudit
38              Temporarily remove dontaudits  from  policy.   Reverts  whenever
39              policy is rebuilt
40
41       -i,--install=MODULE_PKG
42              install/replace a module package

44       -u,--upgrade=MODULE_PKG
45              deprecated, alias for --install
46
47       -b,--base=MODULE_PKG
48              deprecated, alias for --install
49
50       -r,--remove=MODULE_NAME
51              remove existing module at desired priority (defaults to -X 400)
52
53       -l[KIND],--list-modules[=KIND]
54              display list of installed modules (other than base)
55
56       KIND:
57
58       standard
59              list highest priority, enabled, non-base modules
60
61       full   list all modules
62
63       -X,--priority=PRIORITY
64              set priority for following operations (1-999)
65
66       -e,--enable=MODULE_NAME
67              enable module
68
69       -d,--disable=MODULE_NAME
70              disable module
71
72       -E,--extract=MODULE_PKG
73              Extract  a  module  from  the store as an HLL or CIL file to the
74              current directory.  A module is extracted as HLL by default. The
75              name of the module written is <module-name>.<lang_ext>
76

OPTIONS

89
90       -C,--ignore-module-cache

EXAMPLE

115       # Install or replace a base policy package.
116       $ semodule -b base.pp
117       # Install or replace a non-base policy package.
118       $ semodule -i httpd.pp
119       # Install or replace all non-base modules in the current directory.
120       # This syntax can be used with -i/u/r/E, but no other option can be entered after the module names
121       $ semodule -i *.pp
122       # Install or replace all modules in the current directory.
123       $ ls *.pp | grep -Ev "base.pp|enableaudit.pp" | xargs /usr/sbin/semodule -b base.pp -i
124       # List non-base modules.
125       $ semodule -l
126       # List all modules including priorities
127       $ semodule -lfull
128       # Remove a module at priority 100
129       $ semodule -X 100 -r wireshark
130       # Turn on all AVC Messages for which SELinux currently is "dontaudit"ing.
131       $ semodule -DB
132       # Turn "dontaudit" rules back on.
133       $ semodule -B
134       # Disable a module (all instances of given module across priorities will be disabled).
135       $ semodule -d alsa
136       # Install a module at a specific priority.
137       $ semodule -X 100 -i alsa.pp
138       # List all modules.
139       $ semodule --list=full
140       # Set an alternate path for the policy root
141       $ semodule -B -p "/tmp"
142       # Set an alternate path for the policy store root
143       $ semodule -B -S "/tmp/var/lib/selinux"
144       # Write the HLL version of puppet and the CIL version of wireshark
145       # modules at priority 400 to the current working directory
146       $ semodule -X 400 --hll -E puppet --cil -E wireshark
