About
hbsdctl.rb is a C extension that binds libhbsdcontrol from the hardenedbsd project to Ruby. Through this library, you can query what features are available and if root, enable or disable those features for a given file.
Examples
Available features
As a regular user account, you can obtain a list of available features. But to enable or disable those features a superuser account is required:
#!/usr/bin/env ruby
# As a regular user account
require 'hbsdctl'
BSD::Control
.available_features
.each do
print "The ", _1.name, " feature is available", "\n"
end
Enable feature
As a superuser account, you can enable or disable features for a given file. The example enables the mprotect feature for the emacs binary:
#!/usr/bin/env ruby
# As a root account
require 'hbsdctl'
BSD::Control
.feature!(:mprotect)
.enable!("/usr/local/bin/emacs-29.2")
