18 This manual page describes the restorecon program.
19 This program is primarily used to set the security context (extended
21 attributes) on one or more files.
22 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 If a file object does not have a context, restorecon will write the de‐
29 fault context to the file object's extended attributes. If a file ob‐
30 ject has a context, restorecon will only modify the type portion of the
31 security context. The -F option will force a replacement of the entire
32 context.
33 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 It is the same executable as setfiles but operates in a slightly dif‐
40 ferent manner depending on its argv[0].
41
44 -e directory
45 exclude a directory (repeat the option to exclude more than one
46 directory, Requires full path).
47 -f infilename
49 infilename contains a list of files to be processed. Use “-” for
50 stdin.
51 -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 -h, -? display usage information and exit.
57 -i ignore files that do not exist.
59 -I ignore digest to force checking of labels even if the stored
61 SHA256 digest matches the specfiles SHA256 digest. The digest
62 will then be updated provided there are no errors. See the NOTES
63 section for further details.
64 -D Set or update any directory SHA256 digests. Use this option to
66 enable usage of the security.sehash extended attribute.
67 -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 -n don't change any file labels (passive check). To display the
74 files whose labels would be changed, add -v.
75 -o outfilename
77 Deprecated - This option is no longer supported.
78 -p show progress by printing the number of files in 1k blocks un‐
80 less relabeling the entire OS, that will then show the approxi‐
81 mate percentage complete. Note that the -p and -v options are
82 mutually exclusive.
83 -R, -r change files and directories file labels recursively (descend
85 directories).
86 -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 -W display warnings about entries that had no matching files by
92 outputting the selabel_stats(3) results.
93 -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 -x prevent restorecon from crossing file system boundaries.
104 -T nthreads
106 use up to nthreads threads. Specify 0 to create as many threads
107 as there are available CPU cores; 1 to use only a single thread
108 (default); or any positive number to use the given number of
109 threads (if possible).
110 ARGUMENTS
113 pathname ... The pathname for the file(s) to be relabeled.
114
116 1. restorecon by default does not operate recursively on directories.
117 Paths leading up the final component of the file(s) are canonical‐
118 ized using realpath(3) before labeling.
119 2. If the pathname specifies the root directory and the -vR or -vr op‐
121 tions are set and the audit system is running, then an audit event
122 is automatically logged stating that a "mass relabel" took place
123 using the message label FS_RELABEL.
124 3. To improve performance when relabeling file systems recursively
126 (i.e. the -R or -r option is set), the -D option to restorecon will
127 cause it to store a SHA256 digest of the default specfiles set in
128 an extended attribute named security.sehash on each directory spec‐
129 ified in pathname ... once the relabeling has been completed suc‐
130 cessfully. These digests will be checked should restorecon -D be
131 rerun with the same pathname parameters. See selinux_restorecon(3)
132 for further details.
133 The -I option will ignore the SHA256 digest from each directory
135 specified in pathname ... and provided the -n option is NOT set
136 and recursive mode is set, files will be relabeled as required with
137 the digests then being updated provided there are no errors.
138
141 Fix labeling of /var/www/ including all sub-directories and list all context changes
142 # restorecon -rv /var/www/
143 List mislabeled files in user home directory and what the correct label should be
144 # restorecon -nvr ~
145 Fix labeling of files listed in file_list file, ignoring any that do not exist
146 # restorecon -vif file_list
