From 4c4e764e23cd7d103868a73a0cdb5a7bdcaa4bea Mon Sep 17 00:00:00 2001 From: Matthew Wild Date: Fri, 7 May 2021 17:03:49 +0100 Subject: mod_c2s, mod_s2s, mod_component, mod_bosh, mod_websockets: Set default stanza size limits c2s/bosh/ws streams will default to 256KB, s2s and components to 512KB. These values are aligned with ejabberd's default settings, which should reduce issues related to inconsistent size limits between servers on the XMPP network. The previous default (10MB) is excessive for any production server, and allows significant memory usage by even unauthenticated sessions. --- plugins/mod_component.lua | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'plugins/mod_component.lua') diff --git a/plugins/mod_component.lua b/plugins/mod_component.lua index b41204a2..51d731c7 100644 --- a/plugins/mod_component.lua +++ b/plugins/mod_component.lua @@ -27,6 +27,7 @@ local hosts = prosody.hosts; local log = module._log; local opt_keepalives = module:get_option_boolean("component_tcp_keepalives", module:get_option_boolean("tcp_keepalives", true)); +local stanza_size_limit = module:get_option_number("component_stanza_size_limit", module:get_option_number("s2s_stanza_size_limit", 1024*512)); local sessions = module:shared("sessions"); @@ -297,7 +298,7 @@ function listener.onconnect(conn) session.log("info", "Incoming Jabber component connection"); - local stream = new_xmpp_stream(session, stream_callbacks); + local stream = new_xmpp_stream(session, stream_callbacks, stanza_size_limit); session.stream = stream; session.notopen = true; -- cgit v1.2.3
