setfiles - set SELinux file security contexts. setfiles [ -c policy ] [ -d ] [ -l ] [ -m ] [ -n ] [ -e directory ] [ -p ] [ -s ] [ -v ] [ -W ] [ -F ] [ -I | -D ] spec_file pathname ... This manual page describes the setfiles program.

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 option, to 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 option).

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 context, setfiles will only modify the type portion of the security context. The -F option will force a replacement of the entire context.

-c check the validity of the contexts against the specified binary policy.

-d show what specification matched each file (do not abort validation after ABORT_ON_ERRORS errors).

-e directory directory to exclude (repeat option for more than one directory).

-f infilename infilename contains a list of files to be processed. Use \*(lq - \*(rq 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.

-l log changes in file labels to syslog.

-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).

-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.

-q Deprecated, was only used to stop printing inode association parameters.

-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 /

-s take a list of files from standard input instead of using a pathname from the command line (equivalent to \*(lq "-f -" \*(rq ).

-v show changes in file labels and output any inode association parameters. 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.

spec_file The specification file which contains lines of the following form:

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.
