semanage.conf - global configuration file for the SELinux
Management library
The semanage.conf file is usually located under the directory
/etc/selinux and it is used for run-time configuration of the
behavior of the SELinux Management library.
Each line should contain a configuration parameter followed by the
equal sign ("=") and then followed by the configuration value for
that parameter. Anything after the "#" symbol is ignored similarly
to empty lines.
The following parameters are allowed:
module-store
Specify how the SELinux Management library should
interact with the SELinux policy store. When set to
"direct", the SELinux Management library writes to
the SELinux policy module store directly (this is
the default setting). Otherwise a socket path or a
server name can be used for the argument. If the
argument begins with "/" (as in "/foo/bar"), it
represents the path to a named socket that should be
used to connect the policy management server. If
the argument does not begin with a "/" (as in
"example.com:4242"), it should be interpreted as the
name of a remote policy management server to be used
through a TCP connection (default port is 4242
unless a different one is specified after the server
name using the colon to separate the two fields).
root Specify an alternative root path to use for the
store. The default is "/"
store-root
Specify an alternative store_root path to use. The
default is "/var/lib/selinux"
compiler-directory
Specify an alternative directory that contains HLL
to CIL compilers. The default value is
"/usr/libexec/selinux/hll".
ignore-module-cache
Whether or not to ignore the cache of CIL modules
compiled from HLL. It can be set to either "true" or
"false" and is set to "false" by default. If the
cache is ignored, then all CIL modules are
recompiled from their HLL modules.
policy-version
When generating the policy, by default semanage will
set the policy version to POLICYDB_VERSION_MAX, as
defined in <sepol/policydb/policydb.h>. Change this
setting if a different version needs to be set for
the policy.
target-platform
The target platform to generate policies for. Valid
values are "selinux" and "xen", and is set to
"selinux" by default.
expand-check
Whether or not to check "neverallow" rules when
executing all semanage command. It can be set to
either "0" (disabled) or "1" (enabled) and by
default it is enabled. There might be a large
penalty in execution time if this option is enabled.
file-mode
By default the permission mode for the run-time
policy files is set to 0644.
save-previous
It controls whether the previous module directory is
saved after a successful commit to the policy store
and it can be set to either "true" or "false". By
default it is set to "false" (the previous version
is deleted).
save-linked
It controls whether the previously linked module is
saved (with name "base.linked") after a successful
commit to the policy store. It can be set to either
"true" or "false" and by default it is set to
"false" (the previous module is deleted).
ignoredirs
List, separated by ";", of directories to ignore
when setting up users homedirs. Some distributions
use this to stop labeling /root as a homedir.
usepasswd
Whether or not to enable the use getpwent() to
obtain a list of home directories to label. It can
be set to either "true" or "false". By default it
is set to "true".
disable-genhomedircon
It controls whether or not the genhomedircon
function is executed when using the semanage command
and it can be set to either "false" or "true". By
default the genhomedircon functionality is enabled
(equivalent to this option set to "false").
handle-unknown
This option overrides the kernel behavior for
handling permissions defined in the kernel but
missing from the actual policy. It can be set to
"deny", "reject" or "allow". By default the setting
from the policy is taken.
bzip-blocksize
It should be in the range 0-9. A value of 0 means no
compression. By default the bzip block size is set
to 9 (actual block size value is obtained after
multiplication by 100000).
bzip-small
When set to "true", the bzip algorithm shall try to
reduce its system memory usage. It can be set to
either "true" or "false" and by default it is set to
"false".
remove-hll
When set to "true", HLL files will be removed after
compilation into CIL. In order to delete HLL files
already compiled into CIL, modules will need to be
recompiled with the ignore-module-cache option set
to 'true' or using the ignore-module-cache option
with semodule. The remove-hll option can be set to
either "true" or "false" and by default it is set to
"false".
Please note that since this option deletes all HLL
files, an updated HLL compiler will not be able to
recompile the original HLL file into CIL. In order
to compile the original HLL file into CIL, the same
HLL file will need to be reinstalled.
optimize-policy
When set to "true", the kernel policy will be
optimized upon rebuilds. It can be set to either
"true" or "false" and by default it is set to
"true".
multiple-decls
When set to "true", duplicate type, type attribute,
and role declarations will be allowed. It can be
set to either "true" or "false" and by default it is
set to "true".
For certain tasks the SELinux Management library resorts to
running external commands. For the following commands their path
and arguments can be overridden:
load_policy
Command to load a kernel policy. Requires no
argument. Defaults to /sbin/load_policy with
no arguments.
setfiles
Command to verify file context definitions.
Requires two arguments, the path to the
kernel policy and the path to the file
context definition file. Defaults to
/sbin/setfiles with the arguments '-q -c $@
$<'.
sefcontext_compile
Command to compile a file context definition
file. Requires one argument, the path to the
to be compiled file context definition file.
Defaults to /sbin/sefcontext_compile with the
argument '$@'.
Either path or args can be omitted. The argument string
must contain '$@' for the first required argument, and '$<'
for the second one. The syntax for overriding an external
command property is:
[name]
path = /path/to/command
args = --flag
[end]
Example
[sefcontext_compile]
path = /usr/sbin/sefcontext_compile
args = -r $@
[end]
Optionally the SELinux Management library can invoke
external commands to verify source modules (verify module),
linked modules (verify linked), and kernel policies (verify
kernel). The syntax is identical to the above command
overrides. The program should exit with a value of 0 on
success, and non zero on failure.
