Ubuntu Manpage: restorecon - restore file(s) default SELinux security contexts.

NAME

       restorecon - restore file(s) default SELinux security contexts.

SYNOPSIS

       restorecon [-r|-R] [-m] [-n] [-p] [-v] [-i] [-F] [-W] [-I|-D] [-e directory] pathname ...

       restorecon [-f infilename] [-e directory] [-r|-R] [-m] [-n] [-p] [-v] [-i] [-F] [-W] [-I|-D]

DESCRIPTION

       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].

OPTIONS

-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.restorecon_last 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.

ARGUMENTS
pathname ... The pathname for the file(s) to be relabeled.

NOTES

       1.  restorecon  does  not  follow  symbolic  links  and  by  default  it  does not operate recursively on
           directories.

       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.restorecon_last on the directory  specified  in  each  pathname ...
           once the relabeling has been completed successfully. This digest 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
           digest then being updated provided there are no errors.
