2016-12-14prop224: Introduce the new introduction point code.George Kadianakis
(pun not intended) Now our code supports both legacy and prop224 ESTABLISH_INTRO cells :) hs_intro_received_establish_intro() is the new entry point.
2016-12-14prop224: Add code that generates ESTABLISH_INTRO cells.George Kadianakis
Currently unused. It will only be used for creating ESTABLISH_INTRO cells in unittests :)
2016-12-14prop224 prepwork: Use of HS circuitmap in existing HS code.George Kadianakis
The new HS circuitmap API replaces old public functions as follows: circuit_clear_rend_token -> hs_circuitmap_remove_circuit circuit_get_rendezvous -> hs_circuitmap_get_rend_circ circuit_get_intro_point -> hs_circuitmap_get_intro_circ_v2 circuit_set_rendezvous_cookie -> hs_circuitmap_register_rend_circ circuit_set_intro_point_digest -> hs_circuitmap_register_intro_circ_v2 This commit also removes the old rendinfo code that is now unused. It also fixes the broken rendinfo unittests.
2016-12-14prop224 prepwork: Introduce HS circuitmap subsystem.George Kadianakis
The HS circuitmap is a hash table that maps introduction and rendezvous tokens to specific circuits such that given a token it's easy to find the corresponding circuit. It supports rend circuits and v2/v3 intro circuits. It will be used by the prop224 ESTABLISH_INTRO code to register and lookup v3 introduction circuits. The next commit after this removes the old code and fixes the unittests. Please consult both commits while reviewing functionality differences between the old and new code. Let me know if you want this rebased differently :) WRT architectural differences, this commit removes the rendinfo pointer from or_circuit_t. It then adds an hs_token_t pointer and a hashtable node for the HS circuitmap. IIUC, this adds another pointer to the weight of or_circuit_t. Let me know if you don't like this, or if you have suggestions on improving it.
2016-12-14prop224 prepwork: Finish decoupling old ESTABLISH_INTRO creation logic.George Kadianakis
2016-12-14prpo224 prepwork: Decouple legacy ESTABLISH_INTRO creation logic.George Kadianakis
This commit only moves code.
2016-12-14prop224 prepwork: Introduce HMAC-SHA3 function.George Kadianakis

2016-11-09Stop logging single onion and Tor2web long-term one-hop circuitsteor
Single onion services and Tor2web deliberately create long-term one-hop circuits to their intro and rend points, respectively. These log messages are intended to diagnose issue 8387, which relates to circuits hanging around forever for no reason. Fixes bug 20613; bugfix on 0.2.9.1-alpha. Reported by "pastly".

2016-11-08Use va_copy() in pure-windows version of tor_asprintf().Nick Mathewson
It's not okay to use the same varargs list twice, and apparently some windows build environments produce code here that would leave tor_asprintf() broken. Fix for bug 20560; bugfix on 0.2.2.11-alpha when tor_asprintf() was introduced.

Lower exponents mean that delays do not vary as much. This helps test networks bootstrap consistently. Bugfix on 20499.

2016-11-07test: Remove useless HS decode multiple intro pointsDavid Goulet
The test was broken and skipped because the hardcoded cross certificate didn't include the dynamically generated signing key generated by the test. The only way we could have fixed that is extracting the signing key from the hardcoded string and put it in the descriptor object or dynamically generate the cross certificate. In the end, all this was kind of pointless as we already test the decoding of multiple introduction points elsewhere and we don't gain anything with that specific test thus the removal.
