NAME
       semanage.conf - global configuration file for the SELinux Management li-
       brary

DESCRIPTION
       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 parame-
       ter.  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).  Oth-
                     erwise  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  "exam-
                     ple.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 sepa-
                     rate 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 de-
                     fault 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  mod-
                     ules.

              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  val-
                     ues  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" (dis-
                     abled) 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 set-
                     ting 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  ei-
                     ther "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 ac-
                     tual  policy.   It  can be set to "deny", "reject" or "al-
                     low".  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 com-
                     pression.  By default the bzip block size is set to 9 (ac-
                     tual block size value is obtained after multiplication  by
                     100,000).

              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 compi-
                     lation 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 de-
                     fault 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 orig-
                     inal 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  ei-
                     ther "true" or "false" and by default it is set to "true".

       For  certain tasks the SELinux Management library resorts to running ex-
       ternal commands.  For the following commands their  path  and  arguments
       can be overridden:

                     load_policy
                            Command to load a kernel policy.  Requires no argu-
                            ment.   Defaults to /sbin/load_policy with no argu-
                            ments.

                     setfiles
                            Command to verify file  context  definitions.   Re-
                            quires 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  com-
                            piled  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  prop-
              erty 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.
