Nick Mathewson	e525f5697f	Use protocols to see when EXTEND2 support exists. ... (Technically, we could just remove extend2 cell checking entirely, since all Tor versions on our network are required to have it, but let's keep this around as an example of How To Do It.)	2016-09-26 10:56:51 -07:00

Nick Mathewson	a232161f7b	Cover the error cases of parsing protocol versions ... Also, detect an additional failure type. Thanks, tests! (How distinctly I recall thee)	2016-09-26 10:56:50 -07:00
Nick Mathewson	c1be8f9d57	Basic backend for the protocol-versions voting algorithm. ... [This is a brute-force method that potentially uses way too much RAM. Need to rethink this a little. Right now you can DOS an authority by saying "Foo=1-4294967295".]	2016-09-26 10:56:49 -07:00
