.SH DESCRIPTION
|
|
|
|
|
.PP
|
|
|
|
|
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.

semodule: add priority, enabled, and extended listing
This updates the semodule tool with the ability to set the priority for
commands, to enable/disable modules, and extended module listing options
for displaying extra module information (e.g., priority, enabled status,
and language extension).
[semodule priority]
-X --priority set the priority for following operations
Notes:
* This sets the priority for the following operations.
* It can be used any number of times with its effect continuing until
the next priority is specified.
* The default priority is used if no priority has yet been specified.
Impact on current operations:
* Install module
* Without priority - Install at default priority.
* With priority - Install at specified priority.
* New warning when overriding (issued by libsemanage).
* Upgrade module
* Without priority - Upgrade at default priority (current upgrade
semantics apply).
* With priority - Upgrade at specified priority (current upgrade
semantics apply).
* New warning when overriding (issued by libsemanage).
* Remove module
* Without priority - Remove a module at the default if exists.
* With priority - Remove at that priority.
* New info messages (issued by libsemanage):
* If no modules exist at the given priority but do exist at other
priorities, give an info message listing the modules and priority.
* If a new module at a lower priority will become active print a
message.
* If the last module with this name is being removed print a
message.
* Base
* The name of base module on install is fixed to "_base" (performed by
libsemanage).
* Without priority - Install at default priority.
* With priority - Install at specified priority.
* New warning when overriding (issued by libsemanage).
* List modules
* See listing changes below.
Examples:
semodule -i foo.pp
semodule -X 500 -i foo.pp
[semodule enable/disable]
Add enable/disable status:
-e --enable enable the module (at all priorities)
-d --disable disable the module (at all priorities)
Notes:
* Base modules are always enabled and cannot have their enabled/disabled
status changed.
* New error when disabling a base module (from libsemanage).
* New warning when enabling a base module (from libsemanage).
Impact on current operations:
* Install module
* If a module with that name is already installed, then the enabled
status will remain the same after installing the new module.
* New warning when installing a module which will be disabled by
existing enabled status (from libsemanage).
* Upgrade module
* If a module with that name is already installed, then the enabled
status will remain the same after installing the new module.
* New warning when installing a module which will be disabled by
existing enabled status (from libsemanage).
* Remove module
* When the last module with a given name is removed (no more exist at
other priorities) then the enabled status is forgotten.
* Base
* Base modules are always installed enabled and remain so (can't be
disabled).
* List modules
* See listing changes below.
Examples:
semodule -e foo
semodule -d foo
[semodule list]
-l --list list modules as if by -lstandard
-lstandard --list=standard list name and version of highest priority,
enabled, non-base modules sorted alphabetical
by name
-lfull --list=full list all fields of all modules columnated
sorted high priority to low, within priority
alphabetical by name
Impact on current operations:
* List modules
* Default listing stays the same.
* New long options for 'standard' and 'full'.
Examples:
semodule -l
semodule -lstandard
semodule --list=standard
