restorecon_xattr - Man Page

manage security.sehash extended attribute entries added by setfiles(8) or restorecon(8).

Synopsis

restorecon_xattr [-d] [-D] [-m] [-n] [-r] [-v] [-e directory] [-f specfile] pathname

Description

restorecon_xattr will display the SHA256 digests added to extended attributes security.sehash or delete the attribute completely. These attributes are set by restorecon(8) or setfiles(8) to specified directories when relabeling recursively.

restorecon_xattr is useful for managing the extended attribute entries particularly when users forget what directories they ran restorecon(8) or setfiles(8) from.

RAMFS and TMPFS filesystems do not support the security.sehash extended attribute and are automatically excluded from searches.

By default restorecon_xattr will display the SHA256 digests with "Match" appended if they match the default specfile set or the specfile set used with the -f option. Non-matching SHA256 digests will be displayed with "No Match" appended. This feature can be disabled by the -n option.

Options

-d

delete all non-matching security.sehash directory digest entries.

-D

delete all security.sehash directory digest entries.

-m

do not read /proc/mounts to obtain a list of non-seclabel mounts to be excluded from relabeling checks.
Setting -m is useful where there is a non-seclabel fs mounted with a seclabel fs mounted on a directory below this.

-n

Do not append "Match" or "No Match" to displayed digests.

-r

recursively descend directories.

-v

display SHA256 digest generated by specfile set (Note that this digest is not used to match the security.sehash directory digest entries, and is shown for reference only).

-e

directory
directory to exclude (repeat option for more than one directory).

-f

specfile
an optional specfile containing file context entries as described in file_contexts(5). If the option is not specified, then the default file_contexts will be used.

Arguments

pathname

the pathname of the directory tree to be searched.

Example

List all paths that where assigned a checksum by "restorecon/setfiles -D"
# restorecon_xattr -r /
Remove all non-matching checksums
# restorecon_xattr -rd /
