websockets on Freebsd 13.1 connects then immediately disconnects

[rodneygmorgan]

Mosquitto built from ports after tweaks to the libwebsockets port (added LWS_WITH_EXTERNAL_POLL LWS_CALLBACK_ADD_POLL_FD) to Makefile. Both ports build without errors. Issue confirmed with several clients. Once the client connects it immediately disconnects. It appears to happen in websockets.c in the callback_mqtt() function case statement for LWS_CALLBACK_CLOSED. I added a log_printf statement make this assumption. Here is the log file output:

1676606750: New client connected from 10.0.0.193:53052 as mqttjs_a375c484 (p2, c1, k60). 1676606750: Client gonna be disconnected because 'LWS_CALLBACK_CLOSED'. 1676606750: Client mqttjs_a375c484 closed its connection.

mosquitto works perfectly with MQTT protocol. I suspect this is caused by the libwebsockets port (which has no maintainer).

Any help/suggestion to diagnose the root cause is welcome.

Would you care to try out the develop branch? That removes the need for libwebsockets, which simplifies things greatly and improves websockets performance as well. It would be good to have some feedback on it from the freebsd perspective.

Roger, I'll give it a try this week.

develop branch doesn't compile on the latest FreeBSD-13.2 :

Roger,

Finally back with time to work on this. Where can I download the development branch. Specifically for FreeBSD since the websockets library doesn't work on FreeBSD.

@rodneygmorgan https://github.com/eclipse/mosquitto/tree/develop is what you're looking for

Seems like it's fixed in dev branch https://forums.freebsd.org/threads/mosquitto-and-websockets-disconnect-after-initial-packets.89633/#post-634112
