-Changes in version 0.3.0.6 - 2017-04-2?
- Tor 0.3.0.6 is the first stable release of the Tor 0.3.0 series.
-
- XXXXX BLURB HERE.
-
- Below are the changes since 0.2.9.10. For a list of only the changes
- since 0.3.0.5-rc, see the ChangeLog file.
-
- o Major features (directory authority, security):
- - The default for AuthDirPinKeys is now 1: directory authorities
- will reject relays where the RSA identity key matches a previously
- seen value, but the Ed25519 key has changed. Closes ticket 18319.
-
- o Major features (guard selection algorithm):
- - Tor's guard selection algorithm has been redesigned from the
- ground up, to better support unreliable networks and restrictive
- sets of entry nodes, and to better resist guard-capture attacks by
- hostile local networks. Implements proposal 271; closes
- ticket 19877.
-
- o Major features (next-generation hidden services):
- - Relays can now handle v3 ESTABLISH_INTRO cells as specified by
- prop224 aka "Next Generation Hidden Services". Service and clients
- don't use this functionality yet. Closes ticket 19043. Based on
- initial code by Alec Heifetz.
- - Relays now support the HSDir version 3 protocol, so that they can
- can store and serve v3 descriptors. This is part of the next-
- generation onion service work detailled in proposal 224. Closes
- ticket 17238.
-
- o Major features (protocol, ed25519 identity keys):
- - Clients now support including Ed25519 identity keys in the EXTEND2
- cells they generate. By default, this is controlled by a consensus
- parameter, currently disabled. You can turn this feature on for
- testing by setting ExtendByEd25519ID in your configuration. This
- might make your traffic appear different than the traffic
- generated by other users, however. Implements part of ticket
- 15056; part of proposal 220.
- - Relays now understand requests to extend to other relays by their
- Ed25519 identity keys. When an Ed25519 identity key is included in
- an EXTEND2 cell, the relay will only extend the circuit if the
- other relay can prove ownership of that identity. Implements part
- of ticket 15056; part of proposal 220.
- - Relays now use Ed25519 to prove their Ed25519 identities and to
- one another, and to clients. This algorithm is faster and more
- secure than the RSA-based handshake we've been doing until now.
- Implements the second big part of proposal 220; Closes
- ticket 15055.
-
- o Major features (security):
- - Change the algorithm used to decide DNS TTLs on client and server
- side, to better resist DNS-based correlation attacks like the
- DefecTor attack of Greschbach, Pulls, Roberts, Winter, and
- Feamster. Now relays only return one of two possible DNS TTL
- values, and clients are willing to believe DNS TTL values up to 3
- hours long. Closes ticket 19769.
-
- o Major bugfixes (client, onion service, also in 0.2.9.9):
- - Fix a client-side onion service reachability bug, where multiple
- socks requests to an onion service (or a single slow request)
- could cause us to mistakenly mark some of the service's
- introduction points as failed, and we cache that failure so
- eventually we run out and can't reach the service. Also resolves a
- mysterious "Remote server sent bogus reason code 65021" log
- warning. The bug was introduced in ticket 17218, where we tried to
- remember the circuit end reason as a uint16_t, which mangled
- negative values. Partially fixes bug 21056 and fixes bug 20307;
- bugfix on 0.2.8.1-alpha.
-
- o Major bugfixes (crash, directory connections):
- - Fix a rare crash when sending a begin cell on a circuit whose
- linked directory connection had already been closed. Fixes bug
- 21576; bugfix on 0.2.9.3-alpha. Reported by Alec Muffett.
-
- o Major bugfixes (directory authority):
- - During voting, when marking a relay as a probable sybil, do not
- clear its BadExit flag: sybils can still be bad in other ways
- too. (We still clear the other flags.) Fixes bug 21108; bugfix
- on 0.2.0.13-alpha.
-
- o Major bugfixes (DNS):
- - Fix a bug that prevented exit nodes from caching DNS records for
- more than 60 seconds. Fixes bug 19025; bugfix on 0.2.4.7-alpha.
-
- o Major bugfixes (IPv6 Exits):
- - Stop rejecting all IPv6 traffic on Exits whose exit policy rejects
- any IPv6 addresses. Instead, only reject a port over IPv6 if the
- exit policy rejects that port on more than an IPv6 /16 of
- addresses. This bug was made worse by 17027 in 0.2.8.1-alpha,
- which rejected a relay's own IPv6 address by default. Fixes bug
- 21357; bugfix on commit 004f3f4e53 in 0.2.4.7-alpha.
-
- o Major bugfixes (parsing):
- - Fix an integer underflow bug when comparing malformed Tor
- versions. This bug could crash Tor when built with
- --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor
- 0.2.9.8, which were built with -ftrapv by default. In other cases
- it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix
- on 0.0.8pre1. Found by OSS-Fuzz.
- - When parsing a malformed content-length field from an HTTP
- message, do not read off the end of the buffer. This bug was a
- potential remote denial-of-service attack against Tor clients and
- relays. A workaround was released in October 2016, to prevent this
- bug from crashing Tor. This is a fix for the underlying issue,
- which should no longer matter (if you applied the earlier patch).
- Fixes bug 20894; bugfix on 0.2.0.16-alpha. Bug found by fuzzing
- using AFL (http://lcamtuf.coredump.cx/afl/).
-
- o Major bugfixes (scheduler):
- - Actually compare circuit policies in ewma_cmp_cmux(). This bug
- caused the channel scheduler to behave more or less randomly,
- rather than preferring channels with higher-priority circuits.
- Fixes bug 20459; bugfix on 0.2.6.2-alpha.
-
- o Major bugfixes (security, also in 0.2.9.9):
- - Downgrade the "-ftrapv" option from "always on" to "only on when
- --enable-expensive-hardening is provided." This hardening option,
- like others, can turn survivable bugs into crashes--and having it
- on by default made a (relatively harmless) integer overflow bug
- into a denial-of-service bug. Fixes bug 21278 (TROVE-2017-001);
- bugfix on 0.2.9.1-alpha.
-
- o Minor feature (client):
- - Enable IPv6 traffic on the SocksPort by default. To disable this,
- a user will have to specify "NoIPv6Traffic". Closes ticket 21269.
-
- o Minor feature (fallback scripts):
- - Add a check_existing mode to updateFallbackDirs.py, which checks
- if fallbacks in the hard-coded list are working. Closes ticket
- 20174. Patch by haxxpop.
-
- o Minor feature (protocol versioning):
- - Add new protocol version for proposal 224. HSIntro now advertises
- version "3-4" and HSDir version "1-2". Fixes ticket 20656.
-
- o Minor features (ciphersuite selection):
- - Allow relays to accept a wider range of ciphersuites, including
- chacha20-poly1305 and AES-CCM. Closes the other part of 15426.
- - Clients now advertise a list of ciphersuites closer to the ones
- preferred by Firefox. Closes part of ticket 15426.
-
- o Minor features (controller):
- - Add "GETINFO sr/current" and "GETINFO sr/previous" keys, to expose
- shared-random values to the controller. Closes ticket 19925.
- - When HSFETCH arguments cannot be parsed, say "Invalid argument"
- rather than "unrecognized." Closes ticket 20389; patch from
- Ivan Markin.
-
- o Minor features (controller, configuration):
- - Each of the *Port options, such as SocksPort, ORPort, ControlPort,
- and so on, now comes with a __*Port variant that will not be saved
- to the torrc file by the controller's SAVECONF command. This
- change allows TorBrowser to set up a single-use domain socket for
- each time it launches Tor. Closes ticket 20956.
- - The GETCONF command can now query options that may only be
- meaningful in context-sensitive lists. This allows the controller
- to query the mixed SocksPort/__SocksPort style options introduced
- in feature 20956. Implements ticket 21300.
-
- o Minor features (diagnostic, directory client):
- - Warn when we find an unexpected inconsistency in directory
- download status objects. Prevents some negative consequences of
- bug 20593.
-
- o Minor features (directory authorities):
- - Directory authorities now reject descriptors that claim to be
- malformed versions of Tor. Helps prevent exploitation of
- bug 21278.
- - Reject version numbers with components that exceed INT32_MAX.
- Otherwise 32-bit and 64-bit platforms would behave inconsistently.
- Fixes bug 21450; bugfix on 0.0.8pre1.
-
- o Minor features (directory authority):
- - Add a new authority-only AuthDirTestEd25519LinkKeys option (on by
- default) to control whether authorities should try to probe relays
- by their Ed25519 link keys. This option will go away in a few
- releases--unless we encounter major trouble in our ed25519 link
- protocol rollout, in which case it will serve as a safety option.
-
- o Minor features (directory cache):
- - Relays and bridges will now refuse to serve the consensus they
- have if they know it is too old for a client to use. Closes
- ticket 20511.
-
- o Minor features (ed25519 link handshake):
- - Advertise support for the ed25519 link handshake using the
- subprotocol-versions mechanism, so that clients can tell which
- relays can identity themselves by Ed25519 ID. Closes ticket 20552.
-
- o Minor features (entry guards):
- - Add UseEntryGuards to TEST_OPTIONS_DEFAULT_VALUES in order to not
- break regression tests.
- - Require UseEntryGuards when UseBridges is set, in order to make
- sure bridges aren't bypassed. Resolves ticket 20502.
-
- o Minor features (fallback directories):
- - Allow 3 fallback relays per operator, which is safe now that we
- are choosing 200 fallback relays. Closes ticket 20912.
- - Annotate updateFallbackDirs.py with the bandwidth and consensus
- weight for each candidate fallback. Closes ticket 20878.
- - Display the relay fingerprint when downloading consensuses from
- fallbacks. Closes ticket 20908.
- - Exclude relays affected by bug 20499 from the fallback list.
- Exclude relays from the fallback list if they are running versions
- known to be affected by bug 20499, or if in our tests they deliver
- a stale consensus (i.e. one that expired more than 24 hours ago).
- Closes ticket 20539.
- - Make it easier to change the output sort order of fallbacks.
- Closes ticket 20822.
- - Reduce the minimum fallback bandwidth to 1 MByte/s. Part of
- ticket 18828.
- - Require fallback directories to have the same address and port for
- 7 days (now that we have enough relays with this stability).
- Relays whose OnionOO stability timer is reset on restart by bug
- 18050 should upgrade to Tor 0.2.8.7 or later, which has a fix for
- this issue. Closes ticket 20880; maintains short-term fix
- in 0.2.8.2-alpha.
- - Require fallbacks to have flags for 90% of the time (weighted
- decaying average), rather than 95%. This allows at least 73% of
- clients to bootstrap in the first 5 seconds without contacting an
- authority. Part of ticket 18828.
- - Select 200 fallback directories for each release. Closes
- ticket 20881.
-
- o Minor features (fingerprinting resistence, authentication):
- - Extend the length of RSA keys used for TLS link authentication to
- 2048 bits. (These weren't used for forward secrecy; for forward
- secrecy, we used P256.) Closes ticket 13752.
-
- o Minor features (geoip):
- - Update geoip and geoip6 to the April 4 2017 Maxmind GeoLite2
- Country database.
-
- o Minor features (geoip, also in 0.2.9.9):
- - Update geoip and geoip6 to the January 4 2017 Maxmind GeoLite2
- Country database.
-
- o Minor features (infrastructure):
- - Implement smartlist_add_strdup() function. Replaces the use of
- smartlist_add(sl, tor_strdup(str)). Closes ticket 20048.
-
- o Minor features (linting):
- - Enhance the changes file linter to warn on Tor versions that are
- prefixed with "tor-". Closes ticket 21096.
-
- o Minor features (logging):
- - In several places, describe unset ed25519 keys as "<unset>",
- rather than the scary "AAAAAAAA...AAA". Closes ticket 21037.
-
- o Minor features (portability, compilation):
- - Autoconf now checks to determine if OpenSSL structures are opaque,
- instead of explicitly checking for OpenSSL version numbers. Part
- of ticket 21359.
- - Support building with recent LibreSSL code that uses opaque
- structures. Closes ticket 21359.
-
- o Minor features (relay):
- - We now allow separation of exit and relay traffic to different
- source IP addresses, using the OutboundBindAddressExit and
- OutboundBindAddressOR options respectively. Closes ticket 17975.
- Written by Michael Sonntag.
-
- o Minor features (reliability, crash):
- - Try better to detect problems in buffers where they might grow (or
- think they have grown) over 2 GB in size. Diagnostic for
- bug 21369.
-
- o Minor features (testing):
- - During 'make test-network-all', if tor logs any warnings, ask
- chutney to output them. Requires a recent version of chutney with
- the 21572 patch. Implements 21570.
-
- o Minor bugfix (control protocol):
- - The reply to a "GETINFO config/names" request via the control
- protocol now spells the type "Dependent" correctly. This is a
- breaking change in the control protocol. (The field seems to be
- ignored by the most common known controllers.) Fixes bug 18146;
- bugfix on 0.1.1.4-alpha.
- - The GETINFO extra-info/digest/<digest> command was broken because
- of a wrong base16 decode return value check, introduced when
- refactoring that API. Fixes bug 22034; bugfix on 0.2.9.1-alpha.
-
- o Minor bugfix (logging):
- - Don't recommend the use of Tor2web in non-anonymous mode.
- Recommending Tor2web is a bad idea because the client loses all
- anonymity. Tor2web should only be used in specific cases by users
- who *know* and understand the issues. Fixes bug 21294; bugfix
- on 0.2.9.3-alpha.
-
- o Minor bugfixes (bug resilience):
- - Fix an unreachable size_t overflow in base64_decode(). Fixes bug
- 19222; bugfix on 0.2.0.9-alpha. Found by Guido Vranken; fixed by
- Hans Jerry Illikainen.
-
- o Minor bugfixes (build):
- - Replace obsolete Autoconf macros with their modern equivalent and
- prevent similar issues in the future. Fixes bug 20990; bugfix
- on 0.1.0.1-rc.
-
- o Minor bugfixes (certificate expiration time):
- - Avoid using link certificates that don't become valid till some
- time in the future. Fixes bug 21420; bugfix on 0.2.4.11-alpha
-
- o Minor bugfixes (client):
- - Always recover from failures in extend_info_from_node(), in an
- attempt to prevent any recurrence of bug 21242. Fixes bug 21372;
- bugfix on 0.2.3.1-alpha.
- - When clients that use bridges start up with a cached consensus on
- disk, they were ignoring it and downloading a new one. Now they
- use the cached one. Fixes bug 20269; bugfix on 0.2.3.12-alpha.
-
- o Minor bugfixes (code correctness):
- - Repair a couple of (unreachable or harmless) cases of the risky
- comparison-by-subtraction pattern that caused bug 21278.
-
- o Minor bugfixes (config):
- - Don't assert on startup when trying to get the options list and
- LearnCircuitBuildTimeout is set to 0: we are currently parsing the
- options so of course they aren't ready yet. Fixes bug 21062;
- bugfix on 0.2.9.3-alpha.
-
- o Minor bugfixes (configuration):
- - Accept non-space whitespace characters after the severity level in
- the `Log` option. Fixes bug 19965; bugfix on 0.2.1.1-alpha.
- - Support "TByte" and "TBytes" units in options given in bytes.
- "TB", "terabyte(s)", "TBit(s)" and "terabit(s)" were already
- supported. Fixes bug 20622; bugfix on 0.2.0.14-alpha.
-
- o Minor bugfixes (configure, autoconf):
- - Rename the configure option --enable-expensive-hardening to
- --enable-fragile-hardening. Expensive hardening makes the tor
- daemon abort when some kinds of issues are detected. Thus, it
- makes tor more at risk of remote crashes but safer against RCE or
- heartbleed bug category. We now try to explain this issue in a
- message from the configure script. Fixes bug 21290; bugfix
- on 0.2.5.4-alpha.
-
- o Minor bugfixes (consensus weight):
- - Add new consensus method that initializes bw weights to 1 instead
- of 0. This prevents a zero weight from making it all the way to
- the end (happens in small testing networks) and causing an error.
- Fixes bug 14881; bugfix on 0.2.2.17-alpha.
-
- o Minor bugfixes (crash prevention):
- - Fix an (currently untriggerable, but potentially dangerous) crash
- bug when base32-encoding inputs whose sizes are not a multiple of
- 5. Fixes bug 21894; bugfix on 0.2.9.1-alpha.
-
- o Minor bugfixes (dead code):
- - Remove a redundant check for PidFile changes at runtime in
- options_transition_allowed(): this check is already performed
- regardless of whether the sandbox is active. Fixes bug 21123;
- bugfix on 0.2.5.4-alpha.
-
- o Minor bugfixes (descriptors):
- - Correctly recognise downloaded full descriptors as valid, even
- when using microdescriptors as circuits. This affects clients with
- FetchUselessDescriptors set, and may affect directory authorities.
- Fixes bug 20839; bugfix on 0.2.3.2-alpha.
-
- o Minor bugfixes (directory mirrors):
- - Allow relays to use directory mirrors without a DirPort: these
- relays need to be contacted over their ORPorts using a begindir
- connection. Fixes one case of bug 20711; bugfix on 0.2.8.2-alpha.
- - Clarify the message logged when a remote relay is unexpectedly
- missing an ORPort or DirPort: users were confusing this with a
- local port. Fixes another case of bug 20711; bugfix
- on 0.2.8.2-alpha.
-
- o Minor bugfixes (directory system):
- - Bridges and relays now use microdescriptors (like clients do)
- rather than old-style router descriptors. Now bridges will blend
- in with clients in terms of the circuits they build. Fixes bug
- 6769; bugfix on 0.2.3.2-alpha.
- - Download all consensus flavors, descriptors, and authority
- certificates when FetchUselessDescriptors is set, regardless of
- whether tor is a directory cache or not. Fixes bug 20667; bugfix
- on all recent tor versions.
-
- o Minor bugfixes (documentation):
- - Update the tor manual page to document every option that can not
- be changed while tor is running. Fixes bug 21122.
-
- o Minor bugfixes (ed25519 certificates):
- - Correctly interpret ed25519 certificates that would expire some
- time after 19 Jan 2038. Fixes bug 20027; bugfix on 0.2.7.2-alpha.
-
- o Minor bugfixes (fallback directories):
- - Avoid checking fallback candidates' DirPorts if they are down in
- OnionOO. When a relay operator has multiple relays, this
- prioritizes relays that are up over relays that are down. Fixes
- bug 20926; bugfix on 0.2.8.3-alpha.
- - Stop failing when OUTPUT_COMMENTS is True in updateFallbackDirs.py.
- Fixes bug 20877; bugfix on 0.2.8.3-alpha.
- - Stop failing when a relay has no uptime data in
- updateFallbackDirs.py. Fixes bug 20945; bugfix on 0.2.8.1-alpha.
-
- o Minor bugfixes (hidden service):
- - Clean up the code for expiring intro points with no associated
- circuits. It was causing, rarely, a service with some expiring
- introduction points to not open enough additional introduction
- points. Fixes part of bug 21302; bugfix on 0.2.7.2-alpha.
- - Resolve two possible underflows which could lead to creating and
- closing a lot of introduction point circuits in a non-stop loop.
- Fixes bug 21302; bugfix on 0.2.7.2-alpha.
- - Stop setting the torrc option HiddenServiceStatistics to "0" just
- because we're not a bridge or relay. Instead, we preserve whatever
- value the user set (or didn't set). Fixes bug 21150; bugfix
- on 0.2.6.2-alpha.
-
- o Minor bugfixes (hidden services):
- - Make hidden services check for failed intro point connections,
- even when they have exceeded their intro point creation limit.
- Fixes bug 21596; bugfix on 0.2.7.2-alpha. Reported by Alec Muffett.
- - Make hidden services with 8 to 10 introduction points check for
- failed circuits immediately after startup. Previously, they would
- wait for 5 minutes before performing their first checks. Fixes bug
- 21594; bugfix on 0.2.3.9-alpha. Reported by Alec Muffett.
- - Stop ignoring misconfigured hidden services. Instead, refuse to
- start tor until the misconfigurations have been corrected. Fixes
- bug 20559; bugfix on multiple commits in 0.2.7.1-alpha
- and earlier.
-
- o Minor bugfixes (IPv6):
- - Make IPv6-using clients try harder to find an IPv6 directory
- server. Fixes bug 20999; bugfix on 0.2.8.2-alpha.
- - When IPv6 addresses have not been downloaded yet (microdesc
- consensus documents don't list relay IPv6 addresses), use hard-
- coded addresses for authorities, fallbacks, and configured
- bridges. Now IPv6-only clients can use microdescriptors. Fixes bug
- 20996; bugfix on b167e82 from 19608 in 0.2.8.5-alpha.
-
- o Minor bugfixes (memory leak at exit):
- - Fix a small harmless memory leak at exit of the previously unused
- RSA->Ed identity cross-certificate. Fixes bug 17779; bugfix
- on 0.2.7.2-alpha.
-
- o Minor bugfixes (onion services):
- - Allow the number of introduction points to be as low as 0, rather
- than as low as 3. Fixes bug 21033; bugfix on 0.2.7.2-alpha.
-
- o Minor bugfixes (portability):
- - Use "OpenBSD" compiler macro instead of "OPENBSD" or "__OpenBSD__".
- It is supported by OpenBSD itself, and also by most OpenBSD
- variants (such as Bitrig). Fixes bug 20980; bugfix
- on 0.1.2.1-alpha.
-
- o Minor bugfixes (portability, also in 0.2.9.9):
- - Avoid crashing when Tor is built using headers that contain
- CLOCK_MONOTONIC_COARSE, but then tries to run on an older kernel
- without CLOCK_MONOTONIC_COARSE. Fixes bug 21035; bugfix
- on 0.2.9.1-alpha.
- - Fix Libevent detection on platforms without Libevent 1 headers
- installed. Fixes bug 21051; bugfix on 0.2.9.1-alpha.
-
- o Minor bugfixes (relay):
- - Avoid a double-marked-circuit warning that could happen when we
- receive DESTROY cells under heavy load. Fixes bug 20059; bugfix
- on 0.1.0.1-rc.
- - Honor DataDirectoryGroupReadable when tor is a relay. Previously,
- initializing the keys would reset the DataDirectory to 0700
- instead of 0750 even if DataDirectoryGroupReadable was set to 1.
- Fixes bug 19953; bugfix on 0.0.2pre16. Patch by "redfish".
-
- o Minor bugfixes (testing):
- - Fix Raspbian build issues related to missing socket errno in
- test_util.c. Fixes bug 21116; bugfix on 0.2.8.2. Patch by "hein".
- - Remove undefined behavior from the backtrace generator by removing
- its signal handler. Fixes bug 21026; bugfix on 0.2.5.2-alpha.
- - Use bash in src/test/test-network.sh. This ensures we reliably
- call chutney's newer tools/test-network.sh when available. Fixes
- bug 21562; bugfix on 0.2.9.1-alpha.
-
- o Minor bugfixes (tor-resolve):
- - The tor-resolve command line tool now rejects hostnames over 255
- characters in length. Previously, it would silently truncate them,
- which could lead to bugs. Fixes bug 21280; bugfix on 0.0.9pre5.
- Patch by "junglefowl".
-
- o Minor bugfixes (unit tests):
- - Allow the unit tests to pass even when DNS lookups of bogus
- addresses do not fail as expected. Fixes bug 20862 and 20863;
- bugfix on unit tests introduced in 0.2.8.1-alpha
- through 0.2.9.4-alpha.
-
- o Minor bugfixes (util):
- - When finishing writing a file to disk, if we were about to replace
- the file with the temporary file created before and we fail to
- replace it, remove the temporary file so it doesn't stay on disk.
- Fixes bug 20646; bugfix on 0.2.0.7-alpha. Patch by fk.
-
- o Minor bugfixes (Windows services):
- - Be sure to initialize the monotonic time subsystem before using
- it, even when running as an NT service. Fixes bug 21356; bugfix
- on 0.2.9.1-alpha.
-
- o Minor bugfixes (Windows):
- - Check for getpagesize before using it to mmap files. This fixes
- compilation in some MinGW environments. Fixes bug 20530; bugfix on
- 0.1.2.1-alpha. Reported by "ice".
-
- o Code simplification and refactoring:
- - Abolish all global guard context in entrynodes.c; replace with new
- guard_selection_t structure as preparation for proposal 271.
- Closes ticket 19858.
- - Extract magic numbers in circuituse.c into defined variables.
- - Introduce rend_service_is_ephemeral() that tells if given onion
