setfiles - set SELinux file security contexts.
] [-e directory
This manual page describes the setfiles
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
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
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
will only modify the type portion of the security
context. The -F
option will force a replacement of the entire context.
- check the validity of the contexts against the specified
- show what specification matched each file (do not abort
validation after 10 errors).
- -e directory
- directory to exclude (repeat option for more than one
- -f infilename
- infilename contains a list of files to be processed.
Use “-” for stdin.
- 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.
- ignore files that do not exist.
- 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
- Set or update any directory SHA1 digests. Use this option
to enable usage of the security.restorecon_last extended
- log changes in file labels to syslog.
- 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.
- don't change any file labels (passive check).
- -o outfilename
- Deprecated - This option is no longer supported.
- 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
- Deprecated, was only used to stop printing inode
- -r rootpath
- use an alternate root path. Used in meta-selinux for
OpenEmbedded/Yocto builds to label files under rootpath as if they
were at /
- take a list of files from standard input instead of using a
pathname from the command line (equivalent to “-f -”
- show changes in file labels and output any inode
association parameters. Note that the -v and -p options are
- display warnings about entries that had no matching files
by outputting the selabel_stats(3) results.
- 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.
- The specification file which contains lines of the
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>>
that the file is not to have its context changed.
The last matching specification is used. If there are multiple hard links to a
file that match different specifications and those specifications indicate
different security contexts, then a warning is displayed but the file is still
labeled based on the last matching specification other than
- 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.
- setfiles follows symbolic links and operates
recursively on directories.
- If the pathname specifies the root directory and the
-v option is 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.
- 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.restorecon_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
specified 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.
