restorecon(8)               SELinux User Command               restorecon(8)

NAME         top

       restorecon - restore file(s) default SELinux security contexts.

SYNOPSIS         top

       restorecon [-r|-R] [-m] [-n] [-p] [-v] [-i] [-F] [-W] [-I|-D] [-e
       directory] pathname ...

       restorecon [-f infilename] [-e directory] [-r|-R] [-m] [-n] [-p] [-v]
       [-i] [-F] [-W] [-I|-D]

DESCRIPTION         top

       This manual page describes the restorecon program.

       This program is primarily used to set the security context (extended
       attributes) on one or more files.

       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).

       If a file object does not have a context, restorecon will write the
       default context to the file object's extended attributes. If a file
       object has a context, restorecon will only modify the type portion of
       the security context.  The -F option will force a replacement of the
       entire context.

       If a file is labeled with customizable SELinux type (for list of
       customizable types see
       /etc/selinux/{SELINUXTYPE}/contexts/customizable_types), restorecon
       won't reset the label unless the -F option is used.

       It is the same executable as setfiles but operates in a slightly
       different manner depending on its argv[0].

OPTIONS         top

       -e directory
              exclude a directory (repeat the option to exclude more than
              one directory, Requires full path).

       -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
              section for further details.

       -D     Set or update any directory SHA1 digests. Use this option to
              enable usage of the security.restorecon_last extended
              attribute.

       -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).  To display the
              files whose labels would be changed, add -v.

       -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
              approximate percentage complete. Note that the -p and -v
              options are mutually exclusive.

       -R, -r change files and directories file labels recursively (descend
              directories).

       -v     show changes in file labels. Multiple -v options increase the
              verbosity. Note that the -v and -p options are mutually
              exclusive.

       -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.  Useful when input items might contain white space,
              quote marks or backslashes.  The -print0 option of GNU find
              produces input suitable for this mode.

ARGUMENTS         top

              pathname ...  The pathname for the file(s) to be relabeled.

NOTES         top

       1.  restorecon does not follow symbolic links and by default it does
           not operate recursively on directories.

       2.  If the pathname specifies the root directory and the -vR or -vr
           options are set and the audit system is running, then an audit
           event is automatically logged stating that a "mass relabel" took
           place using the message label FS_RELABEL.

       3.  To improve performance when relabeling file systems recursively
           (i.e. the -R or -r option is set), the -D option to restorecon
           will cause it to store a SHA1 digest of the default specfiles set
           in an extended attribute named security.restorecon_last on the
           directory specified in each pathname ...  once the relabeling has
           been completed successfully. This digest will be checked should
           restorecon -D be rerun with the same pathname parameters. See
           selinux_restorecon(3) for further details.

           The -I option will ignore the SHA1 digest from each directory
           specified in pathname ...  and provided the -n option is NOT set
           and recursive mode is set, files will be relabeled as required
           with the digest then being updated provided there are no errors.
