[tor/master] copy the 0.2.2.26-beta changelog to master too

commit e98e1c836106b325aeeb9977a657ef98739ffff1 Author: Roger Dingledine <arma(a)torproject.org> Date: Tue May 17 21:26:13 2011 -0400 copy the 0.2.2.26-beta changelog to master too --- ChangeLog | 134 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 134 insertions(+), 0 deletions(-) diff --git a/ChangeLog b/ChangeLog index 28153f1..79596cc 100644 --- a/ChangeLog +++ b/ChangeLog @@ -143,6 +143,140 @@ Changes in version 0.2.3.1-alpha - 2011-05-05 issue 2379. +Changes in version 0.2.2.26-beta - 2011-05-17 + Tor 0.2.2.26-beta fixes a variety of potential privacy problems. It + also introduces a new "socksport auto" approach that should make it + easier to run multiple Tors on the same system, and does a lot of + cleanup to get us closer to a release candidate. + + o Security/privacy fixes: + - Replace all potentially sensitive memory comparison operations + with versions whose runtime does not depend on the data being + compared. This will help resist a class of attacks where an + adversary can use variations in timing information to learn + sensitive data. Fix for one case of bug 3122. (Safe memcmp + implementation by Robert Ransom based partially on code by DJB.) + - When receiving a hidden service descriptor, check that it is for + the hidden service we wanted. Previously, Tor would store any + hidden service descriptors that a directory gave it, whether it + wanted them or not. This wouldn't have let an attacker impersonate + a hidden service, but it did let directories pre-seed a client + with descriptors that it didn't want. Bugfix on 0.0.6. + - On SIGHUP, do not clear out all TrackHostExits mappings, client + DNS cache entries, and virtual address mappings: that's what + NEWNYM is for. Fixes bug 1345; bugfix on 0.1.0.1-rc. + + o Major features: + - The options SocksPort, ControlPort, and so on now all accept a + value "auto" that opens a socket on an OS-selected port. A + new ControlPortWriteToFile option tells Tor to write its + actual control port or ports to a chosen file. If the option + ControlPortFileGroupReadable is set, the file is created as + group-readable. Now users can run two Tor clients on the same + system without needing to manually mess with parameters. Resolves + part of ticket 3076. + - Set SO_REUSEADDR on all sockets, not just listeners. This should + help busy exit nodes avoid running out of useable ports just + because all the ports have been used in the near past. Resolves + issue 2850. + + o Minor features: + - New "GETINFO net/listeners/(type)" controller command to return + a list of addresses and ports that are bound for listeners for a + given connection type. This is useful when the user has configured + "SocksPort auto" and the controller needs to know which port got + chosen. Resolves another part of ticket 3076. + - Add a new ControlSocketsGroupWritable configuration option: when + it is turned on, ControlSockets are group-writeable by the default + group of the current user. Patch by Jérémy Bobbio; implements + ticket 2972. + - Tor now refuses to create a ControlSocket in a directory that is + world-readable (or group-readable if ControlSocketsGroupWritable + is 0). This is necessary because some operating systems do not + enforce permissions on an AF_UNIX sockets. Permissions on the + directory holding the socket, however, seems to work everywhere. + - Rate-limit a warning about failures to download v2 networkstatus + documents. Resolves part of bug 1352. + - Backport code from 0.2.3.x that allows directory authorities to + clean their microdescriptor caches. Needed to resolve bug 2230. + - When an HTTPS proxy reports "403 Forbidden", we now explain + what it means rather than calling it an unexpected status code. + Closes bug 2503. Patch from Michael Yakubovich. + - Update to the May 1 2011 Maxmind GeoLite Country database. + + o Minor bugfixes: + - Authorities now clean their microdesc cache periodically and when + reading from disk initially, not only when adding new descriptors. + This prevents a bug where we could lose microdescriptors. Bugfix + on 0.2.2.6-alpha. 2230 + - Do not crash when our configuration file becomes unreadable, for + example due to a permissions change, between when we start up + and when a controller calls SAVECONF. Fixes bug 3135; bugfix + on 0.0.9pre6. + - Avoid a bug that would keep us from replacing a microdescriptor + cache on Windows. (We would try to replace the file while still + holding it open. That's fine on Unix, but Windows doesn't let us + do that.) Bugfix on 0.2.2.6-alpha; bug found by wanoskarnet. + - Add missing explanations for the authority-related torrc options + RephistTrackTime, BridgePassword, and V3AuthUseLegacyKey in the + man page. Resolves issue 2379. + - As an authority, do not upload our own vote or signature set to + ourself. It would tell us nothing new, and as of 0.2.2.24-alpha, + it would get flagged as a duplicate. Resolves bug 3026. + - Accept hidden service descriptors if we think we might be a hidden + service directory, regardless of what our consensus says. This + helps robustness, since clients and hidden services can sometimes + have a more up-to-date view of the network consensus than we do, + and if they think that the directory authorities list us a HSDir, + we might actually be one. Related to bug 2732; bugfix on + 0.2.0.10-alpha. + - When a controller changes TrackHostExits, remove mappings for + hosts that should no longer have their exits tracked. Bugfix on + 0.1.0.1-rc. + - When a controller changes VirtualAddrNetwork, remove any mappings + for hosts that were automapped to the old network. Bugfix on + 0.1.1.19-rc. + - When a controller changes one of the AutomapHosts* options, remove + any mappings for hosts that should no longer be automapped. Bugfix + on 0.2.0.1-alpha. + - Do not reset the bridge descriptor download status every time we + re-parse our configuration or get a configuration change. Fixes + bug 3019; bugfix on 0.2.0.3-alpha. + + o Minor bugfixes (code cleanup): + - When loading the microdesc journal, remember its current size. + In 0.2.2, this helps prevent the microdesc journal from growing + without limit on authorities (who are the only ones to use it in + 0.2.2). Fixes a part of bug 2230; bugfix on 0.2.2.6-alpha. + Fix posted by "cypherpunks." + - The microdesc journal is supposed to get rebuilt only if it is + at least _half_ the length of the store, not _twice_ the length + of the store. Bugfix on 0.2.2.6-alpha; fixes part of bug 2230. + - Fix a potential null-pointer dereference while computing a + consensus. Bugfix on tor-0.2.0.3-alpha, found with the help of + clang's analyzer. + - Avoid a possible null-pointer dereference when rebuilding the mdesc + cache without actually having any descriptors to cache. Bugfix on + 0.2.2.6-alpha. Issue discovered using clang's static analyzer. + - If we fail to compute the identity digest of a v3 legacy keypair, + warn, and don't use a buffer-full of junk instead. Bugfix on + 0.2.1.1-alpha; fixes bug 3106. + - Resolve an untriggerable issue in smartlist_string_num_isin(), + where if the function had ever in the future been used to check + for the presence of a too-large number, it would have given an + incorrect result. (Fortunately, we only used it for 16-bit + values.) Fixes bug 3175; bugfix on 0.1.0.1-rc. + - Require that introduction point keys and onion handshake keys + have a public exponent of 65537. Starts to fix bug 3207; bugfix + on 0.2.0.10-alpha. + + o Removed features: + - Caches no longer download and serve v2 networkstatus documents + unless FetchV2Networkstatus flag is set: these documents haven't + haven't been used by clients or relays since 0.2.0.x. Resolves + bug 3022. + + Changes in version 0.2.2.25-alpha - 2011-04-29 Tor 0.2.2.25-alpha fixes many bugs: hidden service clients are more robust, routers no longer overreport their bandwidth, Win7 should crash
