Changes in version 0.4.7.2-alpha - 2021-10-26
|
||||
This version is the second alpha release of the 0.4.7.x series. Two
|
||||
major features were added which are congestion control (prop334) for
|
||||
network performance and the MiddleOnly flag (prop335) voted by the
|
||||
authorities used to pin relays to the middle position for various
|
||||
network health reasons. This version also fixes numerous bugfixes.
|
||||
|
||||
The congestion control feature, detailed in proposal 324, still needs
|
||||
more work before we can enabled it by default. It is currently in its
|
||||
testing and tuning phase which means that you should expect more
|
||||
0.4.7.x alphas as congestion control gets stabilized and tuned for
|
||||
optimal performance. And so, at this release, it can not be used
|
||||
without a custom patch.
|
||||
|
||||
o Major features (congestion control):
|
||||
- Implement support for flow control over congestion controlled
|
||||
circuits. This work comes from proposal 324. Closes ticket 40450.
|
||||
|
||||
o Major features (directory authority):
|
||||
- Add a new consensus method to handle MiddleOnly specially. When
|
||||
enough authorities are using this method, then any relay tagged
|
||||
with the MiddleOnly flag will have its Exit, Guard, HSDir, and
|
||||
V2Dir flags automatically cleared, and will have its BadExit flag
|
||||
automatically set. Implements part of proposal 335.
|
||||
- Authorities can now be configured to label relays as "MiddleOnly".
|
||||
When voting for this flag, authorities automatically vote against
|
||||
Exit, Guard, HSDir, and V2Dir; and in favor of BadExit. Implements
|
||||
part of proposal 335. Based on a patch from Neel Chauhan.
|
||||
|
||||
o Major bugfix (relay, metrics):
|
||||
- On the MetricsPort, the DNS error statistics are not reported by
|
||||
record type ("record=...") anymore due to a libevent bug
|
||||
(https://github.com/libevent/libevent/issues/1219). Fixes bug
|
||||
40490; bugfix on 0.4.7.1-alpha.
|
||||
|
||||
o Major bugfixes (relay, overload state):
|
||||
- Report the general overload state for DNS timeout errors only if
|
||||
X% of all DNS queries over Y seconds are errors. Before that, it
|
||||
only took 1 timeout to report the overload state which was just
|
||||
too low of a threshold. The X and Y values are 1% and 10 minutes
|
||||
respectively but they are also controlled by consensus parameters.
|
||||
Fixes bug 40491; bugfix on 0.4.6.1-alpha.
|
||||
|
||||
o Minor feature (authority, relay):
|
||||
- Reject End-Of-Life relays running version 0.4.2.x, 0.4.3.x,
|
||||
0.4.4.x and 0.4.5 alphas/rc. Closes ticket 40480.
|
||||
|
||||
o Minor feature (onion service v2):
|
||||
- Onion service v2 addresses are now not recognized anymore by tor
|
||||
meaning a bad hostname is returned when attempting to pass it on a
|
||||
SOCKS connection. No more deprecation log is emitted client side.
|
||||
Closes ticket 40476.
|
||||
- See https://blog.torproject.org/v2-deprecation-timeline for
|
||||
details on how to transition from v2 to v3.
|
||||
|
||||
o Minor features (bridge):
|
||||
- We now announce the URL to Tor's new bridge status at
|
||||
https://bridges.torproject.org/ when Tor is configured to run as a
|
||||
bridge relay. Closes ticket 30477.
|
||||
|
||||
o Minor features (fallbackdir):
|
||||
- Regenerate fallback directories for October 2021. Close
|
||||
ticket 40493.
|
||||
|
||||
o Minor features (logging, heartbeat):
|
||||
- When a relay receives a cell that isn't encrypted properly for it,
|
||||
but the relay is the last hop on the circuit, the relay now counts
|
||||
how many cells of this kind it receives, on how many circuits, and
|
||||
reports this information in the log. Previously, we'd log each
|
||||
cell at PROTOCOL_WARN level, which is far too verbose to be
|
||||
useful. Fixes part of ticket 40400.
|
||||
|
||||
o Minor features (testing):
|
||||
- We now have separate fuzzers for the inner layers of v3 onion
|
||||
service descriptors, to prevent future bugs like 40392. Closes
|
||||
ticket 40488.
|
||||
|
||||
o Minor bugfixes (compilation):
|
||||
- Fix compilation error when __NR_time is not defined. Fixes bug
|
||||
40465; bugfix on 0.2.5.5-alpha. Patch by Daniel Pinto.
|
||||
|
||||
o Minor bugfixes (dirauth, bandwidth scanner):
|
||||
- Add the AuthDirDontVoteOnDirAuthBandwidth dirauth config parameter
|
||||
to avoid voting on bandwidth scanner weights to v3 directory
|
||||
authorities. Fixes bug 40471; bugfix on 0.2.2.1-alpha. Patch by
|
||||
Neel Chauhan.
|
||||
|
||||
o Minor bugfixes (fragile-hardening, sandbox):
|
||||
- When building with --enable-fragile-hardening, add or relax Linux
|
||||
seccomp rules to allow AddressSanitizer to execute normally if the
|
||||
process terminates with the sandbox active. This has the side
|
||||
effect of disabling the filtering of file- and directory-open
|
||||
requests on most systems and dilutes the effectiveness of the
|
||||
sandbox overall, as a wider range of system calls must be
|
||||
permitted. Fixes bug 11477; bugfix on 0.2.5.4-alpha.
|
||||
|
||||
o Minor bugfixes (logging):
|
||||
- If a channel has never received, transmitted a cell or seen a
|
||||
client, do not calculate time diffs against 1/1/1970 but log
|
||||
another prettier message. Fixes bug 40182; bugfix on 0.2.4.4.
|
||||
|
||||
o Minor bugfixes (onion service):
|
||||
- Fix a warning BUG that would occur often on heavily loaded onion
|
||||
service leading to filling the logs with useless warnings. Fixes
|
||||
bug 34083; bugfix on 0.3.2.1-alpha.
|
||||
|
||||
o Minor bugfixes (onion service, config):
|
||||
- Fix a memory leak for a small config line string that could occur
|
||||
if the service failed to be configured from file properly. Fixes
|
||||
bug 40484; bugfix on 0.3.2.1-alpha.
|
||||
|
||||
o Minor bugfixes (onion service, TROVE-2021-008):
|
||||
- Only log once any v2 access attempts in order to not pollute the
|
||||
logs with warnings and avoid recording the times on disk when v2
|
||||
access was attempted. Important to note that the onion address was
|
||||
_never_ logged. That is a Low security issue. Fixes bug 40474;
|
||||
bugfix on 0.4.5.8.
|
||||
- Note that due to #40476 which removes v2 support entirely, this
|
||||
log line is not emitted anymore. We still mention this in the
|
||||
changelog because it is a low security TROVE.
|
||||
|
||||
o Minor bugfixes (usability):
|
||||
- Do not log "RENDEZVOUS1 cell with unrecognized rendezvous cookie"
|
||||
at LOG_PROTOCOL_WARN; instead log it at DEBUG. This warning can
|
||||
happen naturally if a client gives up on a rendezvous circuit
|
||||
after sending INTRODUCE1. Fixes part of bug 40400; bugfix
|
||||
on 0.1.1.13-alpha.
|
||||
- Do not log "circuit_receive_relay_cell failed" at
|
||||
LOG_PROTOCOL_WARN; instead log it at DEBUG. In every case where we
|
||||
would want to log this as a protocol warning, we are already
|
||||
logging another warning from inside circuit_receive_relay_cell.
|
||||
Fixes part of bug 40400; bugfix on 0.1.1.9-alpha.
|
||||
|
||||
o Code simplification and refactoring:
|
||||
- Lower the official maximum for "guard-extreme-restriction-percent"
|
||||
to 100. This has no effect on when the guard code will generate a
|
||||
warning, but it makes the intent of the option clearer. Fixes bug
|
||||
40486; bugfix on 0.3.0.1-alpha.
|
||||
|
||||
o Testing:
|
||||
- Add unit tests for the Linux seccomp sandbox. Resolves
|
||||
issue 16803.
|
||||
|
||||
o Code simplification and refactoring (rust):
|
||||
- Remove Rust support and its associated code. It is unsupported and
|
||||
Rust focus should be shifted to arti. Closes 40469.
|
||||
|
||||
o Testing (CI, chutney):
|
||||
- Bump the data size that chutney transmit to 5MB in order to
|
||||
trigger flow control and congestion window code. Closes
|
||||
ticket 40485.
