NAME¶
semodule - Manage SELinux policy modules.
SYNOPSIS¶
semodule [option]... MODE...
DESCRIPTION¶
semodule is the tool used to manage SELinux policy modules, including
installing, upgrading, listing and removing modules. semodule may also be used
to force a rebuild of policy from the module store and/or to force a reload of
policy without performing any other transaction. semodule acts on module
packages created by semodule_package. Conventionally, these files have a .pp
suffix (policy package), although this is not mandated in any way.
MODES¶
- -R, --reload
- force a reload of policy
- -B, --build
- force a rebuild of policy (also reloads unless -n is used)
- -D, --disable_dontaudit
- Temporarily remove dontaudits from policy. Reverts whenever policy is
rebuilt
- -i,--install=MODULE_PKG
- install/replace a module package
- -u,--upgrade=MODULE_PKG
- deprecated, alias for --install
- -b,--base=MODULE_PKG
- deprecated, alias for --install
- -r,--remove=MODULE_NAME
- remove existing module at desired priority (defaults to -X 400)
- -l[KIND],--list-modules[=KIND]
- display list of installed modules (other than base)
- KIND:
- standard
- list highest priority, enabled, non-base modules
- full
- list all modules
- -X,--priority=PRIORITY
- set priority for following operations (1-999)
- -e,--enable=MODULE_NAME
- enable module
- -d,--disable=MODULE_NAME
- disable module
- -E,--extract=MODULE_PKG
- Extract a module from the store as an HLL or CIL file to the current
directory. A module is extracted as HLL by default. The name of the module
written is <module-name>.<lang_ext>
OPTIONS¶
- -s,--store
- name of the store to operate on
- -n,--noreload,-N
- do not reload policy after commit
- -h,--help
- prints help message and quit
- -P,--preserve_tunables
- Preserve tunables in policy
- -C,--ignore-module-cache
- Recompile CIL modules built from HLL files
- -p,--path
- Use an alternate path for the policy root
- -S,--store-path
- Use an alternate path for the policy store root
- -v,--verbose
- be verbose
- -c,--cil
- Extract module as a CIL file. This only affects the --extract option and
only modules listed in --extract after this option.
- -H,--hll
- Extract module as an HLL file. This only affects the --extract option and
only modules listed in --extract after this option.
EXAMPLE¶
# Install or replace a base policy package.
$ semodule -b base.pp
# Install or replace a non-base policy package.
$ semodule -i httpd.pp
# Install or replace all non-base modules in the current directory.
# This syntax can be used with -i/u/r/E, but no other option can be entered after the module names
$ semodule -i *.pp
# Install or replace all modules in the current directory.
$ ls *.pp | grep -Ev "base.pp|enableaudit.pp" | xargs /usr/sbin/semodule -b base.pp -i
# List non-base modules.
$ semodule -l
# List all modules including priorities
$ semodule -lfull
# Remove a module at priority 100
$ semodule -X 100 -r wireshark
# Turn on all AVC Messages for which SELinux currently is "dontaudit"ing.
$ semodule -DB
# Turn "dontaudit" rules back on.
$ semodule -B
# Disable a module (all instances of given module across priorities will be disabled).
$ semodule -d alsa
# Install a module at a specific priority.
$ semodule -X 100 -i alsa.pp
# List all modules.
$ semodule --list=full
# Set an alternate path for the policy root
$ semodule -B -p "/tmp"
# Set an alternate path for the policy store root
$ semodule -B -S "/tmp/var/lib/selinux"
# Write the HLL version of puppet and the CIL version of wireshark
# modules at priority 400 to the current working directory
$ semodule -X 400 --hll -E puppet --cil -E wireshark
