* Log descriptions of nodes, not just nicknames.Nick Mathewson2011-05-15
| | | | | | | | | | | | | | This patch introduces a few new functions in router.c to produce a more helpful description of a node than its nickame, and then tweaks nearly all log messages taking a nickname as an argument to call these functions instead. There are a few cases where I left the old log messages alone: in these cases, the nickname was that of an authority (whose nicknames are useful and unique), or the message already included an identity and/or an address. I might have missed a couple more too. This is a fix for bug 3045.

| * Hand-conversion and audit phase of memcmp transitionNick Mathewson2011-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here I looked at the results of the automated conversion and cleaned them up as follows: If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I changed it to a fast_memcmp or fast_memeq. Otherwise if there was a tor_memcmp that could turn into a tor_memneq or tor_memeq, I converted it. This wants close attention. [*] I'm erring on the side of caution here, and leaving some things as tor_memcmp that could in my opinion use the data-dependent fast_memcmp variant.

* | Add a circuit_purpose_to_string() function, and use itNick Mathewson2011-04-27
| | | | | | | | | | We had a circuit_purpose_to_controller_string() function, but it was pretty coarse-grained and didn't try to be human-readable.
* | When cannibalizing a circuit, make sure it has no ExcludeNodes on itNick Mathewson2011-04-26

* | | Use timevals, not time_t, when expiring circuits.Nick Mathewson2011-03-30
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | We've got millisecond timers now, we might as well use them. This change won't actually make circuits get expiered with microsecond precision, since we only call the expiry functions once per second. Still, it should avoid the situation where we have a circuit get expired too early because of rounding. A couple of the expiry functions now call tor_gettimeofday: this should be cheap since we're only doing it once per second. If it gets to be called more often, though, we should onsider having the current time be an argument again.
* | Sanity-check consensus param valuesSebastian Hahn2011-01-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to make sure that the worst thing that a weird consensus param can do to us is to break our Tor (and only if the other Tors are reliably broken in the same way) so that the majority of directory authorities can't pull any attacks that are worse than the DoS that they can trigger by simply shutting down. One of these worse things was the cbtnummodes parameter, which could lead to heap corruption on some systems if the value was sufficiently large. This commit fixes this particular issue and also introduces sanity checking for all consensus parameters.

* | Clear cell queues when marking or truncating a circuit.Nick Mathewson2010-07-30
| | | | | | | | | | | | | | | | | | At best, this patch helps us avoid sending queued relayed cells that would get ignored during the time between when a destroy cell is sent and when the circuit is finally freed. At worst, it lets us release some memory a little earlier than it would otherwise. Fix for bug #1184. Bugfix on 0.2.0.1-alpha.

| | | | | | | | | | | | | | | | In rare cases, we could cannibalize a one-hop circuit, ending up with a two-hop circuit. This circuit would not be actually used, but we should prevent its creation in the first place. Thanks to outofwords and swissknife for helping to analyse this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two big changes here: - We store active circuits in a priority queue for each or_conn, rather than doing a linear search over all the active circuits before we send each cell. - Rather than multiplying every circuit's cell-ewma by a decay factor every time we send a cell (thus normalizing the value of a current cell to 1.0 and a past cell to alpha^t), we instead only scale down the cell-ewma every tick (ten seconds atm), normalizing so that a cell sent at the start of the tick has value 1.0).
| * | Favor quiet circuits when choosing which order to relay cells in.Can Tang2009-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each circuit is ranked in terms of how many cells from it have been relayed recently, using a time-weighted average. This patch has been tested this on a private Tor network on PlanetLab, and gotten improvements of 12-35% in time it takes to fetch a small web page while there's a simultaneous large data transfer going on simultaneously.

| * | Refactor the safe_str_*() API to make more sense.Nick Mathewson2009-12-15
| | | | | | | | | | | | | | | | | | The new rule is: safe_str_X() means "this string is a piece of X information; make it safe to log." safe_str() on its own means "this string is a piece of who-knows-what; make it safe to log".

|/ / | | | | | | | | | | | | | | Some *_free functions threw asserts when passed NULL. Now all of them accept NULL as input and perform no action when called that way. This gains us consistence for our free functions, and allows some code simplifications where an explicit null check is no longer necessary.
