| * Fix a logic error in circuit_stream_is_being_handled.Nick Mathewson2013-12-21
| | | | | | | | | | | | | | | | | | | | When I introduced the unusable_for_new_circuits flag in 62fb209d837f3f551, I had a spurious ! in the circuit_stream_is_being_handled loop. This made us decide that non-unusable circuits (that is, usable ones) were the ones to avoid, and caused it to launch a bunch of extra circuits. Fixes bug 10456; bugfix on 0.2.4.12-alpha.

| |/ | | | | | | | | | | | | Roger spotted this on tor-dev in his comments on proposal 221. We etect DESTROY vs everything else, since arma likes network timeout indicating failure but not overload indicating failure.

| | * use !cbt_disabled in place of LearnCBT to avoid needless circsNick Mathewson2013-09-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This would make us do testing circuits "even when cbt is disabled by consensus, or when we're a directory authority, or when we've failed to write cbt history to our state file lately." (Roger's words.) This is a fix for 9671 and an improvement in our fix for 5049. The original misbehavior was in 0.2.2.14-alpha; the incomplete fix was in 0.2.3.17-beta.

| * | On END_REASON_EXITPOLICY, mark circuit as unusable for that address.Nick Mathewson2013-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also, don't call the exit node 'reject *' unless our decision to pick that node was based on a non-summarized version of that node's exit policy. rransom and arma came up with the ideas for this fix. Fix for 7582; the summary-related part is a bugfix on 0.2.3.2-alpha.

| * | Stop frobbing timestamp_dirty as our sole means to mark circuits unusableNick Mathewson2013-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a number of places, we decrement timestamp_dirty by MaxCircuitDirtiness in order to mark a stream as "unusable for any new connections. This pattern sucks for a few reasons: * It is nonobvious. * It is error-prone: decrementing 0 can be a bad choice indeed. * It really wants to have a function. It can also introduce bugs if the system time jumps backwards, or if MaxCircuitDirtiness is increased. So in this patch, I add an unusable_for_new_conns flag to origin_circuit_t, make it get checked everywhere it should (I looked for things that tested timestamp_dirty), and add a new function to frob it. For now, the new function does still frob timestamp_dirty (after checking for underflow and whatnot), in case I missed any cases that should be checking unusable_for_new_conns. Fixes bug 6174. We first used this pattern in 516ef41ac1fd26f338c, which I think was in 0.0.2pre26 (but it could have been 0.0.2pre27).
* | | Fix 8447: use %u to format circid_t.Nick Mathewson2013-03-10
|/ / | | | | | | | | | | | | | | | | Now that circid_t is 4 bytes long, the default integer promotions will leave it alone when sizeof(int) == 4, which will leave us formatting an unsigned as an int. That's technically undefined behavior. Fixes bug 8447 on bfffc1f0fc7616a25c32da2eb759dade4651659e. Bug not in any released Tor.

* | | Don't immediately count cannibalized circs as used.Mike Perry2013-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since they use RELAY_EARLY (which can be seen by all hops on the path), it's not safe to say they actually count as a successful use. There are also problems with trying to allow them to finish extending due to the circuit purpose state machine logic. It is way less complicated (and possibly more semantically coherent) to simply wait until we actually try to do something with them before claiming we 'used' them. Also, we shouldn't call timed out circuits 'used' either, for semantic consistency.
* | | Implement Path use bias accounting.Mike Perry2013-01-18
| | | | | | | | | | | | | | | | | | | | | Path use bias measures how often we can actually succeed using the circuits we actually try to use. It is a subset of path bias accounting, but it is computed as a separate statistic because the rate of client circuit use may vary depending on use case.

| | | | | | | | | | | | | | | | | | | | | | | | In general, if we tried to use a circ for a stream, but then decided to place that stream on a different circuit, we need to probe the original circuit before deciding it was a "success". We also need to do the same for cannibalized circuits that go unused.
