[doctor/master] Drop config option for ignoring authorities

commit cf116bb9d3ef6f4cf75d6f94b9a3bb99ef304598 Author: Damian Johnson <atagar(a)torproject.org> Date: Wed Nov 12 09:01:32 2014 -0800 Drop config option for ignoring authorities We just had this due to turtles. Now that Stem no longer includes it among the authorities it enumerates there's no need for this.

[tor/master] Fix: don't report timeout when closing parallel intro points
by nickm＠torproject.org 12 Nov '14

12 Nov '14

commit 34eb007d2201bad44bd6b72681f2c3552445dfc4 Author: David Goulet <dgoulet(a)ev0ke.net> Date: Mon Nov 10 14:38:53 2014 -0500 Fix: don't report timeout when closing parallel intro points When closing parallel introduction points, the given reason (timeout) was actually changed to "no reason" thus when the circuit purpose was CIRCUIT_PURPOSE_C_INTRODUCE_ACK_WAIT, we were reporting an introduction point failure and flagging it "unreachable". After three times, that intro point gets removed from the rend cache object. In the case of CIRCUIT_PURPOSE_C_INTRODUCING, the intro point was flagged has "timed out" and thus not used until the connection to the HS is closed where that flag gets reset. This commit adds an internal circuit reason called END_CIRC_REASON_IP_NOW_REDUNDANT which tells the closing circuit mechanism to not report any intro point failure. This has been observed while opening hundreds of connections to an HS on different circuit for each connection. This fix makes this use case to work like a charm. Fixes #13698.
