mod_firewall: Update user marks to store instantly via map store The original approach was to keep marks in memory only, and persist them at shutdown. That saves I/O, at the cost of potentially losing marks on an unclean shutdown. This change persists marks instantly, which may have some performance overhead but should be more "correct". It also splits the marking/unmarking into an event which may be watched or even fired by other modules.

local allowed_presence_types = { probe = true, unavailable = true };

function filter_presence(event)
	local stanza = event.stanza;
	local presence_type = stanza.attr.type;
	if presence_type == nil or allowed_presence_types[presence_type] then
		return;
	end
	return true; -- Drop
end

module:hook("pre-presence/bare", filter_presence, 200); -- Client sending
module:hook("presence/bare", filter_presence, 200); -- Client receiving
