.TH "restorecon" "8" "10 June 2016" "" "SELinux User Command"
.SH "NAME"
restorecon \- restore file(s) default SELinux security contexts.

.SH "SYNOPSIS"
.B restorecon
.I [\-R] [\-m] [\-n] [\-p] [\-v] [\-I] [\-e directory] pathname...
.P
.B restorecon
.I \-f infilename [\-e directory] [\-R] [\-m] [\-n] [\-p] [\-v] [\-F] [\-I]

.SH "DESCRIPTION"
This manual page describes the
.BR restorecon
program.
.P
This program is primarily used to set the security context
(extended attributes) on one or more files.
.P
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).
.P
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.
.P
It is the same executable as
.BR setfiles
but operates in a slightly different manner depending on its argv[0].

.SH "OPTIONS"
.TP
.B \-e directory
exclude a directory (repeat the option to exclude more than one directory, Requires full path).
.TP
.B \-f infilename
infilename contains a list of files to be processed. Use \- for stdin.
.TP
.B \-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.
.TP
.B \-h, \-?
display usage information and exit.
.TP
.B \-i
ignore files that do not exist.
.TP
.B \-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
.B NOTES
section for further details.
.TP
.B \-m
do not read
.B /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.
.TP
.B \-n
don't change any file labels (passive check).  To display the files whose labels would be changed, add \-v.
.TP
.B \-o outfilename
Deprecated, SELinux policy will probably block this access.  Use shell redirection to save list of files with incorrect context in filename.
.TP
.B \-p
show progress by printing * every STAR_COUNT files unless relabeling the entire
OS, that will then show the approximate percentage complete. Note that the
.B \-p
and
.B \-v
options are mutually exclusive.
.TP
.B \-R, \-r
change files and directories file labels recursively (descend directories).
.br
.TP
.B \-v
show changes in file labels. Note that the
.B \-v
and
.B \-p
options are mutually exclusive.
.TP
.B \-W
display warnings about entries that had no matching files by outputting the
.BR selabel_stats (3)
results.
.TP
.B \-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
.B \-print0
option of GNU
.B find
produces input suitable for this mode.
.TP
.SH "ARGUMENTS"
.B pathname...
The pathname for the file(s) to be relabeled.
.SH "NOTES"
.IP "1." 4
.B restorecon
does not follow symbolic links and by default it does not
operate recursively on directories.
.IP "2." 4
If the
.B pathname
specifies the root directory and the
.B \-vR
or
.B \-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
.BR FS_RELABEL .
.IP "3." 4
To improve performance when relabeling file systems recursively (i.e. the
.B \-R
or
.B \-r
option is set),
.B restorecon
will write an SHA1 digest of the default specfiles set to an extended
attribute named
.IR security.restorecon_last
to the directory specified in each
.B pathname...
once the relabeling has been completed successfully. This digest will be
checked should
.B restorecon
be rerun with the same
.B pathname
parameters. See
.BR selinux_restorecon (3)
for further details.
.sp
The
.B \-I
option will ignore the SHA1 digest from each directory specified in
.B pathname...
and provided the
.B \-n
option is NOT set and recursive mode is set, files will be relabeled as
required with the digest then being updated provided there are no errors.
