DESCRIPTION

18       This manual page describes the restorecon program.
19
20       This  program  is  primarily used to set the security context (extended
21       attributes) on one or more files.
22
23       It can also be run at any other time to correct inconsistent labels, to
24       add  support  for newly-installed policy or, by using the -n option, to
25       passively check whether the file contexts are all set as  specified  by
26       the active policy (default behavior).
27
28       If  a  file  object  does not have a context, restorecon will write the
29       default context to the file object's extended  attributes.  If  a  file
30       object  has  a context, restorecon will only modify the type portion of
31       the security context.  The -F option will force a  replacement  of  the
32       entire context.
33
34       If  a  file is labeled with customizable SELinux type (for list of cus‐
35       tomizable  types   see   /etc/selinux/{SELINUXTYPE}/contexts/customiza‐
36       ble_types),  restorecon  won't  reset the label unless the -F option is
37       used.
38
39       It is the same executable as setfiles but operates in a  slightly  dif‐
40       ferent manner depending on its argv[0].

OPTIONS

44       -e directory
45              exclude  a directory (repeat the option to exclude more than one
46              directory, Requires full path).
47
48       -f infilename
49              infilename contains a list of files to be processed. Use “-” for
50              stdin.
51
52       -F     Force  reset  of  context to match file_context for customizable
53              files, and the default file context, changing  the  user,  role,
54              range portion as well as the type.
55
56       -h, -? display usage information and exit.
57
58       -i     ignore files that do not exist.
59
60       -I     ignore  digest  to  force  checking of labels even if the stored
61              SHA1 digest matches the specfiles SHA1 digest. The  digest  will
62              then be updated provided there are no errors. See the NOTES sec‐
63              tion for further details.
64
65       -D     Set or update any directory SHA1 digests.  Use  this  option  to
66              enable usage of the security.restorecon_last extended attribute.
67
68       -m     do not read /proc/mounts to obtain a list of non-seclabel mounts
69              to be excluded from relabeling checks.  Setting this  option  is
70              useful  where there is a non-seclabel fs mounted with a seclabel
71              fs mounted on a directory below this.
72
73       -n     don't change any file labels (passive check).   To  display  the
74              files whose labels would be changed, add -v.
75
76       -o outfilename
77              Deprecated - This option is no longer supported.
78
79       -p     show  progress  by  printing  the  number  of files in 1k blocks
80              unless relabeling the entire OS, that will then show the approx‐
81              imate  percentage  complete. Note that the -p and -v options are
82              mutually exclusive.
83
84       -R, -r change files and directories file  labels  recursively  (descend
85              directories).
86
87       -v     show  changes  in  file labels. Multiple -v options increase the
88              verbosity. Note that the -v and -p options are  mutually  exclu‐
89              sive.
90
91       -W     display  warnings  about  entries  that had no matching files by
92              outputting the selabel_stats(3) results.
93
94       -0     the separator for the input items is  assumed  to  be  the  null
95              character  (instead  of  the  white  space).  The quotes and the
96              backslash characters are also treated as normal characters  that
97              can form valid input.  This option finally also disables the end
98              of file string, which is treated like any other argument.   Use‐
99              ful  when  input items might contain white space, quote marks or
100              backslashes.  The -print0 option  of  GNU  find  produces  input
101              suitable for this mode.
102
103
104       ARGUMENTS
105              pathname ...  The pathname for the file(s) to be relabeled.
106

NOTES

108       1.  restorecon  does  not  follow symbolic links and by default it does
109           not operate recursively on directories.
110
111       2.  If the pathname specifies the root directory and  the  -vR  or  -vr
112           options  are  set  and  the  audit system is running, then an audit
113           event is automatically logged stating that a  "mass  relabel"  took
114           place using the message label FS_RELABEL.
115
116       3.  To  improve  performance  when  relabeling file systems recursively
117           (i.e. the -R or -r option is set), the -D option to restorecon will
118           cause  it to store a SHA1 digest of the default specfiles set in an
119           extended attribute named security.restorecon_last on the  directory
120           specified  in  each pathname ...  once the relabeling has been com‐
121           pleted successfully. This digest will be checked should  restorecon
122           -D be rerun with the same pathname parameters. See selinux_restore‐
123           con(3) for further details.
124
125           The -I option will ignore the SHA1 digest from each directory spec‐
126           ified  in  pathname ...   and provided the -n option is NOT set and
127           recursive mode is set, files will be relabeled as required with the
128           digest then being updated provided there are no errors.
