setfiles(8)                  SELinux User Command                  setfiles(8)
NAME
       setfiles - set SELinux file security contexts.
SYNOPSIS
       setfiles  [-c policy] [-d] [-l] [-m] [-n] [-e directory] [-p] [-s] [-v]
       [-W] [-F] [-I|-D] spec_file pathname ...
DESCRIPTION
       This manual page describes the setfiles program.
       This program is primarily  used  to  initialize  the  security  context
       fields  (extended  attributes)  on one or more filesystems (or parts of
       them).  Usually it is initially run as part of the SELinux installation
       process (a step commonly known as labeling).
       It can also be run at any other time to correct inconsistent labels, to
       add support for newly-installed policy or, by using the -n  option,  to
       passively  check  whether the file contexts are all set as specified by
       the active policy (default behavior) or by some other policy  (see  the
       -c option).
       If  a  file  object  does  not  have a context, setfiles will write the
       default context to the file object's extended  attributes.  If  a  file
       object has a context, setfiles will only modify the type portion of the
       security context.  The -F option will force a replacement of the entire
       context.
OPTIONS
       -c     check  the validity of the contexts against the specified binary
              policy.
       -d     show what specification matched each file. Not affected by "-q"
       -e directory
              directory to exclude (repeat option for  more  than  one  direc-
              tory).
       -f infilename
              infilename contains a list of files to be processed. Use "-" for
              stdin.
       -F     Force reset of context to match  file_context  for  customizable
              files,  and  the  default file context, changing the user, role,
              range portion as well as the type.
       -h, -? display usage information and exit.
       -i     ignore files that do not exist.
       -I     ignore digest to force checking of labels  even  if  the  stored
              SHA1  digest  matches the specfiles SHA1 digest. The digest will
              then be updated provided there are no errors. See the NOTES sec-
              tion for further details.
       -D     Set  or  update  any  directory SHA1 digests. Use this option to
              enable usage of the security.restorecon_last extended attribute.
       -l     log changes in file labels to syslog.
       -m     do not read /proc/mounts to obtain a list of non-seclabel mounts
              to  be  excluded from relabeling checks.  Setting this option is
              useful where there is a non-seclabel fs mounted with a  seclabel
              fs mounted on a directory below this.
       -n     don't change any file labels (passive check).
       -o outfilename
              Deprecated - This option is no longer supported.
       -p     show  progress  by  printing  the  number  of files in 1k blocks
              unless relabeling the entire OS, that will then show the approx-
              imate  percentage  complete. Note that the -p and -v options are
              mutually exclusive.
       -q     Deprecated, was only used to  stop  printing  inode  association
              parameters.
       -r rootpath
              use  an alternate root path. Used in meta-selinux for OpenEmbed-
              ded/Yocto builds to label files under rootpath as if  they  were
              at /
       -s     take  a  list  of  files  from standard input instead of using a
              pathname from the command line (equivalent to "-f -" ).
       -v     show changes in file labels and  output  any  inode  association
              parameters.  Note that the -v and -p options are mutually exclu-
              sive.
       -W     display warnings about entries that had  no  matching  files  by
              outputting the selabel_stats(3) results.
       -0     the  separator  for  the  input  items is assumed to be the null
              character (instead of the white  space).   The  quotes  and  the
              backslash  characters are also treated as normal characters that
              can form valid input.  This option finally also disables the end
              of  file string, which is treated like any other argument.  Use-
              ful when input items might contain white space, quote  marks  or
              backslashes.   The  -print0  option  of  GNU find produces input
              suitable for this mode.
ARGUMENTS
       spec_file
              The specification file which contains  lines  of  the  following
              form:
              regexp [type] context | <<none>>
                     The  regular  expression  is  anchored at both ends.  The
                     optional type field specifies the file type as  shown  in
                     the  mode  field  by the ls(1) program, e.g.  -- to match
                     only regular files or -d to match only directories.   The
                     context can be an ordinary security context or the string
                     <<none>> to specify that the file is not to have its con-
                     text changed.
                     The  last  matching  specification  is used. If there are
                     multiple hard links to a file that match different speci-
                     fications  and  those  specifications  indicate different
                     security contexts, then a warning is  displayed  but  the
                     file is still labeled based on the last matching specifi-
                     cation other than <<none>>.
       pathname ...
              The pathname for the root directory of each file  system  to  be
              relabeled  or  a  specific  directory  within  a filesystem that
              should be recursively descended and relabeled or the pathname of
              a  file  that should be relabeled.  Not used if the -f or the -s
              option is used.
NOTES
       1.  setfiles follows symbolic links and operates recursively on  direc-
           tories.
       2.  If  the  pathname specifies the root directory and the -v option is
           set and the audit system is running, then an audit event  is  auto-
           matically logged stating that a "mass relabel" took place using the
           message label FS_RELABEL.
       3.  To improve performance when relabeling file systems recursively the
           -D  option  to setfiles will cause it to store a SHA1 digest of the
           spec_file set in  an  extended  attribute  named  security.restore-
           con_last  on the directory specified in each pathname ...  once the
           relabeling has been completed successfully.  This  digest  will  be
           checked  should  setfiles  -D  be rerun with the same spec_file and
           pathname parameters. See selinux_restorecon(3) for further details.
           The -I option will ignore the SHA1 digest from each directory spec-
           ified in pathname ...  and provided the -n option is NOT set, files
           will be relabeled as required with the digest  then  being  updated
           provided there are no errors.
