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
"false".
