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 bugs introduced in earlier releases, including
|
||||
stability and reliability fixes on earlier versions of Tor.
|
||||
|
||||
o Major bugfixes (Exit nodes):
|
||||
- Fix an issue causing high-bandwidth exit nodes to fail a majority
|
||||
or all of their DNS requests, making them basically unsuitable for
|
||||
regular usage in Tor circuits. The problem is related to
|
||||
libevent's DNS handling, but we can work around it in Tor. Fixes
|
||||
bugs 21394 and 18580; bugfix on 0.1.2.2-alpha which introduced
|
||||
eventdns. Credit goes to Dhalgren for identifying and finding a
|
||||
workaround to this bug and to gamambel, arthuredelstein and arma
|
||||
in helping to track it down and analyze it.
|
||||
|
||||
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 in 0.2.9.2-alpha. Closes ticket 21031.
|
||||
|
||||
o Minor features (testing):
|
||||
- Our fuzzing tests now test the encrypted portions of the v3 hidden
|
||||
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 hidden 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):
|
||||
- Downgrade a warning to a protocol warning in the case the ed25519
|
||||
key is not consistent between the descriptor and micro descriptor
|
||||
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, hidden service):
|
||||
- Mention that the HiddenServiceNumIntroductionPoints option is 0-10
|
||||
for v2 service and 0-20 for v3 service. Fixes bug 24115; bugfix
|
||||
on 0.3.2.1-alpha.
|
||||
|
||||
o Minor bugfixes (memory leak):
|
||||
- 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
|
||||
continuously computing it over and over again. Fixes bug 23623;
|
||||
bugfix on 0.3.2.1-alpha.
|
||||
- Properly retry HSv3 descriptor fetches in the case where we were
|
||||
initially missing required directory information. Fixes bug 23762;
|
||||
bugfix on 0.3.2.1-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.
