Changes in version 0.3.3.4-alpha - 2018-03-29
|
||||
Tor 0.3.3.4-alpha includes various bugfixes for issues found during
|
||||
the alpha testing of earlier releases in its series. We are
|
||||
approaching a stable 0.3.3.4-alpha release: more testing is welcome!
|
||||
|
||||
o New system requirements:
|
||||
- When built with Rust, Tor now depends on version 0.2.39 of the
|
||||
libc crate. Closes tickets 25310 and 25664.
|
||||
|
||||
o Major bugfixes (relay, connection):
|
||||
- If we have failed to connect to a relay and received a connection
|
||||
refused, timeout, or similar error (at the TCP level), do not try
|
||||
that same address again for 60 seconds after the failure has
|
||||
occurred. Fixes bug 24767; bugfix on 0.0.6.
|
||||
|
||||
o Minor features (geoip):
|
||||
- Update geoip and geoip6 to the March 8 2018 Maxmind GeoLite2
|
||||
Country database. Closes ticket 25469.
|
||||
|
||||
o Minor features (log messages):
|
||||
- Improve log message in the out-of-memory handler to include
|
||||
information about memory usage from the different compression
|
||||
backends. Closes ticket 25372.
|
||||
|
||||
o Minor features (sandbox):
|
||||
- Explicitly permit the poll() system call when the Linux
|
||||
seccomp2-based sandbox is enabled: apparently, some versions of
|
||||
libc use poll() when calling getpwnam(). Closes ticket 25313.
|
||||
|
||||
o Minor bugfixes (C correctness):
|
||||
- Fix a very unlikely (impossible, we believe) null pointer
|
||||
dereference. Fixes bug 25629; bugfix on 0.2.9.15. Found by
|
||||
Coverity; this is CID 1430932.
|
||||
|
||||
o Minor bugfixes (channel, client):
|
||||
- Better identify client connection when reporting to the geoip
|
||||
client cache. Fixes bug 24904; bugfix on 0.3.1.7.
|
||||
|
||||
o Minor bugfixes (compilation):
|
||||
- Fix a C99 compliance issue in our configuration script that caused
|
||||
compilation issues when compiling Tor with certain versions of
|
||||
xtools. Fixes bug 25474; bugfix on 0.3.2.5-alpha.
|
||||
|
||||
o Minor bugfixes (controller, reliability):
|
||||
- Avoid a (nonfatal) assertion failure when extending a one-hop
|
||||
circuit from the controller to become a multihop circuit. Fixes
|
||||
bug 24903; bugfix on 0.2.5.2-alpha.
|
||||
|
||||
o Minor bugfixes (networking):
|
||||
- Tor will no longer reject IPv6 address strings from TorBrowser
|
||||
when they are passed as hostnames in SOCKS5 requests. Fixes bug
|
||||
25036, bugfix on Tor 0.3.1.2.
|
||||
- string_is_valid_hostname() will not consider IP strings to be
|
||||
valid hostnames. Fixes bug 25055; bugfix on Tor 0.2.5.5.
|
||||
|
||||
o Minor bugfixes (onion service v3):
|
||||
- Avoid an assertion failure when the next the next onion service
|
||||
descriptor rotation type is out of sync with the consensus's
|
||||
valid-after time. Instead, log a warning message with extra
|
||||
information, so we can better hunt down the cause of this
|
||||
assertion. Fixes bug 25306; bugfix on 0.3.2.1-alpha.
|
||||
|
||||
o Minor bugfixes (testing):
|
||||
- Avoid intermittent test failures due to a test that had relied on
|
||||
onion service introduction point creation finishing within 5
|
||||
seconds of real clock time. Fixes bug 25450; bugfix
|
||||
on 0.3.1.3-alpha.
|
||||
- Rust crates are now automatically detected and tested. Previously,
|
||||
some crates were not tested by `make test-rust` due to a static
|
||||
string in the `src/test/test_rust.sh` script specifying which
|
||||
crates to test. Fixes bug 25560; bugfix on 0.3.3.3-alpha.
|
||||
|
||||
o Minor bugfixes (testing, benchmarks):
|
||||
- Fix a crash when running benchmark tests on win32 systems. The
|
||||
crash was due to a mutex that wasn't initialized before logging
|
||||
and options were initialized. Fixes bug 25479; bugfix
|
||||
on 0.3.3.3-alpha.
|
||||
|
||||
o Minor bugfixes (warnings, ipv6):
|
||||
- Avoid a bug warning that could occur when trying to connect to a
|
||||
relay over IPv6. This warning would occur on a Tor instance that
|
||||
downloads router descriptors, but prefers to use microdescriptors.
|
||||
Fixes bug 25213; bugfix on 0.3.3.1-alpha.
|
||||
|
||||
o Code simplification and refactoring:
|
||||
- Remove the old (deterministic) directory retry logic entirely:
|
||||
We've used exponential backoff exclusively for some time. Closes
|
||||
ticket 23814.
|
||||
|
||||
o Documentation:
|
||||
- Improved the documentation of AccountingStart parameter. Closes
|
||||
ticket 23635.
|
||||
- Update the documentation for "Log" to include the current list of
|
||||
logging domains. Closes ticket 25378.

still result in intermittent failures (e.g. if the system doing the
