+Changes in version 0.3.2.4-alpha - 2017-11-08
|
|
|
+ Tor 0.3.2.4-alpha is the fourth alpha release in the 0.3.2.x series.
|
|
|
+ It fixes several stability and reliability bugs, especially including
|
|
|
+ a major reliability issue that has been plaguing fast exit relays in
|
|
|
+ recent months.
|
|
|
+
|
|
|
+ o Major bugfixes (exit relays, DNS):
|
|
|
+ - Fix an issue causing DNS to fail on high-bandwidth exit nodes,
|
|
|
+ making them nearly unusable. Fixes bugs 21394 and 18580; bugfix on
|
|
|
+ 0.1.2.2-alpha, which introduced eventdns. Thanks to Dhalgren for
|
|
|
+ identifying and finding a workaround to this bug and to Moritz,
|
|
|
+ Arthur Edelstein, and Roger for helping to track it down and
|
|
|
+ analyze it.
|
|
|
+
|
|
|
+ o Major bugfixes (scheduler, channel):
|
|
|
+ - Stop processing scheduled channels if they closed while flushing
|
|
|
+ cells. This can happen if the write on the connection fails
|
|
|
+ leading to the channel being closed while in the scheduler loop.
|
|
|
+ Fixes bug 23751; bugfix on 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor features (logging, scheduler):
|
|
|
+ - Introduce a SCHED_BUG() function to log extra information about
|
|
|
+ the scheduler state if we ever catch a bug in the scheduler.
|
|
|
+ Closes ticket 23753.
|
|
|
+
|
|
|
+ o Minor features (removed deprecations):
|
|
|
+ - The ClientDNSRejectInternalAddresses flag can once again be set in
|
|
|
+ non-testing Tor networks, so long as they do not use the default
|
|
|
+ directory authorities. This change also removes the deprecation of
|
|
|
+ this flag from 0.2.9.2-alpha. Closes ticket 21031.
|
|
|
+
|
|
|
+ o Minor features (testing):
|
|
|
+ - Our fuzzing tests now test the encrypted portions of v3 onion
|
|
|
+ service descriptors. Implements more of 21509.
|
|
|
+
|
|
|
+ o Minor bugfixes (directory client):
|
|
|
+ - On failure to download directory information, delay retry attempts
|
|
|
+ by a random amount based on the "decorrelated jitter" algorithm.
|
|
|
+ Our previous delay algorithm tended to produce extra-long delays
|
|
|
+ too easily. Fixes bug 23816; bugfix on 0.2.9.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (IPv6, v3 single onion services):
|
|
|
+ - Remove buggy code for IPv6-only v3 single onion services, and
|
|
|
+ reject attempts to configure them. This release supports IPv4,
|
|
|
+ dual-stack, and IPv6-only v3 onion services; and IPv4 and dual-
|
|
|
+ stack v3 single onion services. Fixes bug 23820; bugfix
|
|
|
+ on 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (logging, relay):
|
|
|
+ - Give only a protocol warning when the ed25519 key is not
|
|
|
+ consistent between the descriptor and microdescriptor of a relay.
|
|
|
+ This can happen, for instance, if the relay has been flagged
|
|
|
+ NoEdConsensus. Fixes bug 24025; bugfix on 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (manpage, onion service):
|
|
|
+ - Document that the HiddenServiceNumIntroductionPoints option is
|
|
|
+ 0-10 for v2 services and 0-20 for v3 services. Fixes bug 24115;
|
|
|
+ bugfix on 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (memory leaks):
|
|
|
+ - Fix a minor memory leak at exit in the KIST scheduler. This bug
|
|
|
+ should have no user-visible impact. Fixes bug 23774; bugfix
|
|
|
+ on 0.3.2.1-alpha.
|
|
|
+ - Fix a memory leak when decrypting a badly formatted v3 onion
|
|
|
+ service descriptor. Fixes bug 24150; bugfix on 0.3.2.1-alpha.
|
|
|
+ Found by OSS-Fuzz; this is OSS-Fuzz issue 3994.
|
|
|
+
|
|
|
+ o Minor bugfixes (onion services):
|
|
|
+ - Cache some needed onion service client information instead of
|
|
|
+ constantly computing it over and over again. Fixes bug 23623;
|
|
|
+ bugfix on 0.3.2.1-alpha.
|
|
|
+ - Properly retry HSv3 descriptor fetches when missing required
|
|
|
+ directory information. Fixes bug 23762; bugfix on 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (path selection):
|
|
|
+ - When selecting relays by bandwidth, avoid a rounding error that
|
|
|
+ could sometimes cause load to be imbalanced incorrectly.
|
|
|
+ Previously, we would always round upwards; now, we round towards
|
|
|
+ the nearest integer. This had the biggest effect when a relay's
|
|
|
+ weight adjustments should have given it weight 0, but it got
|
|
|
+ weight 1 instead. Fixes bug 23318; bugfix on 0.2.4.3-alpha.
|
|
|
+ - When calculating the fraction of nodes that have descriptors, and
|
|
|
+ all nodes in the network have zero bandwidths, count the number of
|
|
|
+ nodes instead. Fixes bug 23318; bugfix on 0.2.4.10-alpha.
|
|
|
+ - Actually log the total bandwidth in compute_weighted_bandwidths().
|
|
|
+ Fixes bug 24170; bugfix on 0.2.4.3-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (relay, crash):
|
|
|
+ - Avoid a crash when transitioning from client mode to bridge mode.
|
|
|
+ Previously, we would launch the worker threads whenever our
|
|
|
+ "public server" mode changed, but not when our "server" mode
|
|
|
+ changed. Fixes bug 23693; bugfix on 0.2.6.3-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (testing):
|
|
|
+ - Fix a spurious fuzzing-only use of an uninitialized value. Found
|
|
|
+ by Brian Carpenter. Fixes bug 24082; bugfix on 0.3.0.3-alpha.
|
|
|
+ - Test that IPv6-only clients can use microdescriptors when running
|
|
|
+ "make test-network-all". Requires chutney master 61c28b9 or later.
|
|
|
+ Closes ticket 24109.
