Only send a SYN|ACK packet after Tor connection succeeds (!182) · Merge requests · The Tor Project / Core / onionmasq · GitLab

eta requested to merge send-rst into main Dec 07, 2023

Switch our version of smoltcp to a fork with one small patch applied 1 that lets you withhold sending SYN|ACK packets with a new pause_synack function.
Use it to only send SYN|ACK after we successfully connect on the Tor side of things. This way, we send back a proper RST packet if the connection failed, instead of establishing it and immediately aborting it.

Closes #74 (closed).
