salt.modules.selinux

Execute calls on selinux

Note

This module requires the semanage, setsebool, and semodule commands to be available on the minion. On RHEL-based distributions, ensure that the policycoreutils and policycoreutils-python packages are installed. If not on a Fedora or RHEL-based distribution, consult the selinux documentation for your distribution to ensure that the proper packages are installed.

salt.modules.selinux.fcontext_add_or_delete_policy(action, name, filetype=None, sel_type=None, sel_user=None, sel_level=None)

New in version 2017.7.0.

Adds or deletes the SELinux policy for a given filespec and other optional parameters.

Returns the result of the call to semanage.

Note that you don't have to remove an entry before setting a new one for a given filespec and filetype, as adding one with semanage automatically overwrites a previously configured SELinux context.

Deprecated since version Fluorine.

action
The action to perform. Either add or delete.
name
filespec of the file or directory. Regex syntax is allowed.
file_type
The SELinux filetype specification. Use one of [a, f, d, c, b, s, l, p]. See also man semanage-fcontext. Defaults to 'a' (all files).
sel_type
SELinux context type. There are many.
sel_user
SELinux user. Use semanage login -l to determine which ones are available to you.
sel_level
