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.
