Tor 0.2.0.16-alpha and 0.2.0.17-alpha add a fifth v3 directory authority run by Karsten Loesing, and generally clean up a lot of features and minor bugs. https://www.torproject.org/download#Dev Changes in version 0.2.0.17-alpha - 2008-01-17 o Compile fixes: - Make the tor-gencert man page get included correctly in the tarball. Changes in version 0.2.0.16-alpha - 2008-01-17 o New directory authorities: - Set up gabelmoo (run by Karsten Loesing) as the fifth v3 directory authority. o Major performance improvements: - Switch our old ring buffer implementation for one more like that used by free Unix kernels. The wasted space in a buffer with 1mb of data will now be more like 8k than 1mb. The new implementation also avoids realloc();realloc(); patterns that can contribute to memory fragmentation. o Minor features: - Configuration files now accept C-style strings as values. This helps encode characters not allowed in the current configuration file format, such as newline or #. Addresses bug 557. - Although we fixed bug 539 (where servers would send HTTP status 503 responses _and_ send a body too), there are still servers out there that haven't upgraded. Therefore, make clients parse such bodies when they receive them. - When we're not serving v2 directory information, there is no reason to actually keep any around. Remove the obsolete files and directory on startup if they are very old and we aren't going to serve them. o Minor performance improvements: - Reference-count and share copies of address policy entries; only 5% of them were actually distinct. - Never walk through the list of logs if we know that no log is interested in a given message. o Minor bugfixes: - When an authority has not signed a consensus, do not try to download a nonexistent "certificate with key 00000000". Bugfix on 0.2.0.x. Fixes bug 569. - Fix a rare assert error when we're closing one of our threads: use a mutex to protect the list of logs, so we never write to the list as it's being freed. Bugfix on 0.1.2.x. Fixes the very rare bug 575, which is kind of the revenge of bug 222. - Patch from Karsten Loesing to complain less at both the client and the relay when a relay used to have the HSDir flag but doesn't anymore, and we try to upload a hidden service descriptor. - Stop leaking one cert per TLS context. Fixes bug 582. Bugfix on 0.2.0.15-alpha. - Do not try to download missing certificates until we have tried to check our fallback consensus. Fixes bug 583. - Make bridges round reported GeoIP stats info up to the nearest estimate, not down. Now we can distinguish between "0 people from this country" and "1 person from this country". - Avoid a spurious free on base64 failure. Bugfix on 0.1.2. - Avoid possible segfault if key generation fails in crypto_pk_hybrid_encrypt. Bugfix on 0.2.0. - Avoid segfault in the case where a badly behaved v2 versioning directory sends a signed networkstatus with missing client-versions. Bugfix on 0.1.2. - Avoid segfaults on certain complex invocations of router_get_by_hexdigest(). Bugfix on 0.1.2. - Correct bad index on array access in parse_http_time(). Bugfix on 0.2.0. - Fix possible bug in vote generation when server versions are present but client versions are not. - Fix rare bug on REDIRECTSTREAM control command when called with no port set: it could erroneously report an error when none had happened. - Avoid bogus crash-prone, leak-prone tor_realloc when we're compressing large objects and find ourselves with more than 4k left over. Bugfix on 0.2.0. - Fix a small memory leak when setting up a hidden service. - Fix a few memory leaks that could in theory happen under bizarre error conditions. - Fix an assert if we post a general-purpose descriptor via the control port but that descriptor isn't mentioned in our current network consensus. Bug reported by Jon McLachlan; bugfix on 0.2.0.9-alpha. o Minor features (controller): - Get NS events working again. Patch from tup. - The GETCONF command now escapes and quotes configuration values that don't otherwise fit into the torrc file. - The SETCONF command now handles quoted values correctly. o Minor features (directory authorities): - New configuration options to override default maximum number of servers allowed on a single IP address. This is important for running a test network on a single host. - Actually implement the -s option to tor-gencert. - Add a manual page for tor-gencert. o Minor features (bridges): - Bridge authorities no longer serve bridge descriptors over unencrypted connections. o Minor features (other): - Add hidden services and DNSPorts to the list of things that make Tor accept that it has running ports. Change starting Tor with no ports from a fatal error to a warning; we might change it back if this turns out to confuse anybody. Fixes bug 579.
