+Changes in version 0.4.2.3-alpha - 2019-10-??
|
|
|
+ This release fixes several bugs from the previous alpha release, and
|
|
|
+ from earlier versions of Tor.
|
|
|
+
|
|
|
+ o Major bugfixes (hidden service v3):
|
|
|
+ - Make onion service always use the exact amount of configured intro points
|
|
|
+ (or less due to node exlusion). Before, a service could sometimes pick
|
|
|
+ more intro points than configured with the
|
|
|
+ HiddenServiceNumIntroductionPoints option. Fixes bug 31548; bugfix on
|
|
|
+ 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor feature (hidden service, control port):
|
|
|
+ - The ADD_ONION key blob keyword "BEST" now defaults from RSA1024 (v2) to
|
|
|
+ ED25519-V3 (v3). Closes ticket 29669.
|
|
|
+
|
|
|
+ o Minor features (testing):
|
|
|
+ - When running tests that attempt to look up hostname, replace the libc
|
|
|
+ name lookup functions with ones that do not actually touch the network.
|
|
|
+ This way, the tests complete more quickly in the presence of a slow or
|
|
|
+ missing DNS resolver. Closes ticket 31841.
|
|
|
+
|
|
|
+ o Minor bugfixes (build system):
|
|
|
+ - Interpret --disable-module-dirauth=no correctly.
|
|
|
+ Fixes bug 32124; bugfix on 0.3.4.1-alpha.
|
|
|
+ - Interpret --with-tcmalloc=no correctly.
|
|
|
+ Fixes bug 32124; bugfix on 0.2.0.20-rc.
|
|
|
+ - Stop failing when jemalloc is requested, but tcmalloc is not found.
|
|
|
+ Fixes bug 32124; bugfix on 0.3.5.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (configuration):
|
|
|
+ - When pkg-config is not installed, or a library that depends on
|
|
|
+ pkg-config is not found, tell the user what to do to fix the
|
|
|
+ problem. Fixes bug 31922; bugfix on 0.3.1.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (connection):
|
|
|
+ - Avoid reading data from closed connections, which can cause needless
|
|
|
+ loops in libevent and infinite loops in Shadow. Fixes bug 30344; bugfix
|
|
|
+ on 0.1.1.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (error handling):
|
|
|
+ - Always lock the backtrace buffer before it is used.
|
|
|
+ Fixes bug 31734; bugfix on 0.2.5.3-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (hidden service v3, coverity):
|
|
|
+ - Fix an implicit conversion from ssize_t to size_t discovered by Coverity.
|
|
|
+ Fixes bug 31682; bugfix on 0.4.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (hs-v3, memory leak):
|
|
|
+ - Fix memory leak in unlikely error code path when encoding HS DoS establish
|
|
|
+ intro extension cell. Fixes bug 32063; bugfix on 0.4.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (mainloop, periodic events):
|
|
|
+ - Periodic events enabled flag was not unset properly when shutting down tor
|
|
|
+ cleanly. This had the side effect to not re-enable periodic events when
|
|
|
+ tor_api.h is used to relaunch tor after a shutdown. Fixes bug 32058;
|
|
|
+ bugfix on 0.3.3.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (onion services):
|
|
|
+ - When we clean up intro circuits for a v3 onion service, don't remove
|
|
|
+ circuits that have an established or pending circuit even if ran out of
|
|
|
+ retries. This way, we don't cleanup the circuit of the last retry. Fixes
|
|
|
+ bug 31652; bugfix on 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (pluggable transports):
|
|
|
+ - Remove overly strict assertions that triggers when a pluggable transport
|
|
|
+ is spawned in an unsuccessful manner. Fixes bug 31091; bugfix on 0.4.0.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (process management):
|
|
|
+ - Remove assertion in the Unix process backend. This assertion would trigger
|
|
|
+ when a new process is spawned where the executable is not found leading to
|
|
|
+ a stack trace from the child process. Fixes bug 31810; bugfix on 0.4.0.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (testing):
|
|
|
+ - Avoid intermittent test failures due to a test that had relied on
|
|
|
+ inconsistent timing sources. Fixes bug 31995; bugfix on 0.3.1.3-alpha.
|
|
|
+ - When testing port rebinding, don't busy-wait for tor to log. Instead,
|
|
|
+ actually sleep for a short time before polling again. Also improve the
|
|
|
+ formatting of control commands and log messages.
|
|
|
+ Fixes bug 31837; bugfix on 0.3.5.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (tls, logging):
|
|
|
+ - Log TLS read buffer length bugs once, rather than filling the logs
|
|
|
+ with similar warnings. Fixes bug 31939; bugfix on 0.3.0.4-rc.
|
|
|
+
|
|
|
+ o Documentation:
|
|
|
+ - Correct the description of "GuardLifetime". Fixes bug 31189; bugfix on
|
|
|
+ 0.3.0.1-alpha.
|
|
|
+
|
|
|
+ o Testing:
|
|
|
+ - Disable all but one Travis CI macOS build, to mitigate slow scheduling
|
|
|
+ of Travis macOS jobs. Closes ticket 32177.
|
|
|
+ - Run the chutney IPv6 networks as part of Travis CI.
|
|
|
+ Closes ticket 30860.
|
|
|
+ - Simplify the Travis CI build matrix, and optimise for build time.
|
|
|
+ Closes ticket 31859.
|
|
|
+ - Use Windows Server 2019 instead of Windows Server 2016 in our
|
|
|
+ Appveyor builds. Closes ticket 32086.
