restorecon(8) SELinux User Command restorecon(8)
restorecon - restore file(s) default SELinux security contexts.
restorecon [-r|-R] [-m] [-n] [-p] [-v] [-i] [-F] [-W] [-I|-D]
[-x] [-e directory] pathname ...
restorecon [-f infilename] [-e directory] [-r|-R] [-m] [-n] [-p]
[-v] [-i] [-F] [-W] [-I|-D] [-x] [-T nthreads]
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].
-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.sehash 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.
-x prevent restorecon from crossing file system boundaries.
-T nthreads
use up to nthreads threads. Specify 0 to create as many
threads as there are available CPU cores; 1 to use only a
single thread (default); or any positive number to use the
given number of threads (if possible).
pathname ... The pathname for the file(s) to be
relabeled.
1. restorecon by default does not operate recursively on
directories. Paths leading up the final component of the
file(s) are canonicalized using realpath(3) before labeling.
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.sehash on each directory specified in pathname ...
once the relabeling has been completed successfully. These
digests 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 digests then being updated provided there
are no errors.
