NAME
setfiles - set SELinux file security contexts.
SYNOPSIS
setfiles [-c policy] [-d] [-l] [-m] [-n] [-e directory] [-E] [-p] [-s] [-v] [-W] [-F]
[-I|-D] spec_file pathname ...
DESCRIPTION
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.
OPTIONS
-c check the validity of the contexts against the specified binary policy.
-d show what specification matched each file.
-e directory
directory to exclude (repeat option for more than one directory).
-E treat conflicting specifications as errors, such as where two hardlinks for the
same inode have different contexts.
-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.
-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 “-f -” ).
-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.
ARGUMENTS
spec_file
The specification file which contains lines of the following form:
regexp [type] context | <<none>>
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>> to
specify 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 <<none>>.
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.
NOTES
1. setfiles operates recursively on directories. Paths leading up the final component of
the file(s) are not canonicalized before labeling.
2. 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.
3. 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.sehash on each directory specified in pathname ... once the
relabeling has been completed successfully. These digests 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 digests then being updated provided there are no errors.
