Changes in version 0.2.2.13-alpha - 2010-04-24 o Major bugfixes: - Teach relays to defend themselves from connection overload. Relays now close idle circuits early if it looks like they were intended for directory fetches. Relays are also more aggressive about closing TLS connections that have no circuits on them. Such circuits are unlikely to be re-used, and tens of thousands of them were piling up at the fast relays, causing the relays to run out of sockets and memory. Bugfix on 0.2.0.22-rc (where clients started tunneling their directory fetches over TLS). o Minor features: - Finally get rid of the deprecated and now harmful notion of "clique mode", where directory authorities maintain TLS connections to every other relay. - Directory authorities now do an immediate reachability check as soon as they hear about a new relay. This change should slightly reduce the time between setting up a relay and getting listed as running in the consensus. It should also improve the time between setting up a bridge and seeing use by bridge users. - Directory authorities no longer launch a TLS connection to every relay as they startup. Now that we have 2k+ descriptors cached, the resulting network hiccup is becoming a burden. Besides, authorities already avoid voting about Running for the first half hour of their uptime. Changes in version 0.2.2.12-alpha - 2010-04-20 Tor 0.2.2.12-alpha fixes a critical bug in how directory authorities handle and vote on descriptors. It was causing relays to drop out of the consensus. o Major bugfixes: - Many relays have been falling out of the consensus lately because not enough authorities know about their descriptor for them to get a majority of votes. When we deprecated the v2 directory protocol, we got rid of the only way that v3 authorities can hear from each other about other descriptors. Now authorities examine every v3 vote for new descriptors, and fetch them from that authority. Bugfix on 0.2.1.23. - Fix two typos in tor_vasprintf() that broke the compile on Windows, and a warning in or.h related to bandwidth_weight_rule_t that prevented clean compile on OS X. Fixes bug 1363; bugfix on 0.2.2.11-alpha. - Fix a segfault on relays when DirReqStatistics is enabled and 24 hours pass. Bug found by keb. Fixes bug 1365; bugfix on 0.2.2.11-alpha. o Minor bugfixes: - Demote a confusing TLS warning that relay operators might get when someone tries to talk to their OrPort. It is neither the operator's fault nor can they do anything about it. Fixes bug 1364; bugfix on 0.2.0.14-alpha. |
