Greetings,
We just released two new stables that is 0.4.7.15 and 0.4.8.6 containing an
important fix for onion services affecting congestion control.
Here is the announcement:
https://forum.torproject.org/t/stable-release-0-4-7-15-and-0-4-8-6/9292
Below the ChangeLog for both releases.
Cheers!
Changes in version 0.4.7.15 - 2023-09-18
This version contains an important fix for onion service regarding congestion
control and its reliability. Apart from that, very minor bugfixes. We
strongly recommend all onion service operators to update immediately.
o Major bugfixes (onion service):
- Fix a reliability issue where services were expiring their
introduction points every consensus update. This caused
connectivity issues for clients caching the old descriptor and
intro points. Bug reported and fixed by gitlab user
@hyunsoo.kim676. Fixes bug 40858; bugfix on 0.4.7.5-alpha.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on September 18, 2023.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/09/18.
o Minor features (testing):
- Enable Doxygen and Stem tests for 0.4.8 and clean-up some logic
for handling versions of Tor that are no longer supported. Closes
ticket 40859.
o Minor bugfixes (compression):
- Right after compression/decompression work is done, check for
errors. Before this, we would consider compression bomb before
that and then looking for errors leading to false positive on that
log warning. Fixes bug 40739; bugfix on 0.3.5.1-alpha. Patch
by "cypherpunks".
o Minor bugfixes (compression, zstd):
- Use less frightening language and lower the log-level of our run-
time ABI compatibility check message in our Zstd compression
subsystem. Fixes bug 40815; bugfix on 0.4.3.1-alpha.
Changes in version 0.4.8.6 - 2023-09-18
This version contains an important fix for onion service regarding congestion
control and its reliability. Apart from that, uneeded BUG warnings have been
suppressed especially about a compression bomb seen on relays. We strongly
recommend, in particular onion service operators, to upgrade as soon as
possible to this latest stable.
o Major bugfixes (onion service):
- Fix a reliability issue where services were expiring their
introduction points every consensus update. This caused
connectivity issues for clients caching the old descriptor and
intro points. Bug reported and fixed by gitlab user
@hyunsoo.kim676. Fixes bug 40858; bugfix on 0.4.7.5-alpha.
o Minor features (debugging, compression):
- Log the input and output buffer sizes when we detect a potential
compression bomb. Diagnostic for ticket 40739.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on September 18, 2023.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/09/18.
o Minor bugfix (defensive programming):
- Disable multiple BUG warnings of a missing relay identity key when
starting an instance of Tor compiled without relay support. Fixes
bug 40848; bugfix on 0.4.3.1-alpha.
o Minor bugfixes (bridge authority):
- When reporting a pseudo-networkstatus as a bridge authority, or
answering "ns/purpose/*" controller requests, include accurate
published-on dates from our list of router descriptors. Fixes bug
40855; bugfix on 0.4.8.1-alpha.
o Minor bugfixes (compression, zstd):
- Use less frightening language and lower the log-level of our run-
time ABI compatibility check message in our Zstd compression
subsystem. Fixes bug 40815; bugfix on 0.4.3.1-alpha.
