restorecon(8) SELinux User Command restorecon(8)
NAME
restorecon - restore file(s) default SELinux security contexts.
SYNOPSIS
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]
DESCRIPTION
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 de-
fault context to the file object's extended attributes. If a file ob-
ject 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 cus-
tomizable types see /etc/selinux/{SELINUXTYPE}/contexts/customiza-
ble_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 dif-
ferent manner depending on its argv[0].
OPTIONS
-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 sec-
tion for further details.
-D Set or update any directory SHA1 digests. Use this option to en-
able 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 un-
less relabeling the entire OS, that will then show the approxi-
mate 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 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.
-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).
ARGUMENTS
pathname ... The pathname for the file(s) to be relabeled.
NOTES
1. restorecon by default does not operate recursively on directories.
Paths leading up the final component of the file(s) are canonical-
ized using realpath(3) before labeling.
2. If the pathname specifies the root directory and the -vR or -vr op-
tions 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 speci-
fied in pathname ... once the relabeling has been completed suc-
cessfully. 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 spec-
ified 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.
