From e3d771baf90b7fbc33d56e0ed2558c76f6ad9b24 Mon Sep 17 00:00:00 2001 From: Kim Alvefur Date: Wed, 9 Nov 2022 19:10:16 +0100 Subject: mod_s2s: Retrieve stanza size limit from peer for bidi connections Having mod_s2s know about the bidi namespace is perhaps a bit awkward but putting this in mod_s2s_bidi would be more awkward as it has nothing to do with limits. Some indirection event could be added in the future. --- plugins/mod_s2s.lua | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'plugins') diff --git a/plugins/mod_s2s.lua b/plugins/mod_s2s.lua index e4469c20..6d1a76a0 100644 --- a/plugins/mod_s2s.lua +++ b/plugins/mod_s2s.lua @@ -253,6 +253,13 @@ function module.add_host(module) :text_tag("max-size", string.format("%d", stanza_size_limit)):up(); end end); + module:hook_tag("urn:xmpp:bidi", "bidi", function(session, stanza) + -- Advertising features on bidi connections where no is sent in the other direction + local limits = stanza:get_child("limits", "urn:xmpp:stream-limits:0"); + if limits then + session.outgoing_stanza_size_limit = tonumber(limits:get_child_text("max-size")); + end + end, 100); module:hook("s2s-authenticated", make_authenticated, -1); module:hook("s2s-read-timeout", keepalive, -1); module:hook_stanza("http://etherx.jabber.org/streams", "features", function (session, stanza) -- luacheck: ignore 212/stanza -- cgit v1.2.3
