The access module performs access checks on clients.

The access check is only performed once per client, subsequent checks return the same resolution.

Permissions assigned to a client are configured as arguments to this module, see the example configuration below. A special use-case is Flatpak where the permission management is delegated.

This module sets the PW_KEY_ACCESS property to one of

allowed: the client is explicitly allowed to access all resources
rejected: the client does not have access to any resources and a resource error is generated
restricted: the client is restricted, see note below
flatpak: restricted, special case for clients running inside flatpak, see note below
$access.force: the value of the access.force argument given in the module configuration.
unrestricted: the client is allowed to access all resources. This is the default for clients not listed in any of the access.* options unless the client requested reduced permissions in PW_KEY_CLIENT_ACCESS.

Note: Clients with a resolution other than allowed or rejected rely on an external actor to update that property once permission is granted or rejected.

Module Options

Options specific to the behavior of this module

access.allowed = []: an array of paths of allowed applications
access.rejected = []: an array of paths of rejected applications
access.restricted = []: an array of paths of restricted applications
access.force = <str>: forces an external permissions check (e.g. a flatpak portal)

General options

Options with well-known behavior:

Example configuration

 context.modules = [
  {   name = libpipewire-module-access
      args = {
          access.allowed = [
              /usr/bin/pipewire-media-session
              /usr/bin/important-thing
          ]
 
          access.rejected = [
              /usr/bin/microphone-snooper
          ]
 
          #access.restricted = [ ]
 
          # Anything not in the above lists gets assigned the
          # access.force permission.
          #access.force = flatpak
      }
  }
