Changes in version 0.4.3.1-alpha - 2020-01-2?
This is the first alpha release in the 0.4.3.x series. BLURB MORE
o Major feature (onion service, SOCKS5):
- Introduce a new SocksPort flag named: ExtendedErrors. Detailed in
proposal 304, a number of onion service error codes are now sent back,
if this flag is set, with the SOCKS5 protocol using new custom error
values. Closes ticket 30382;
o Major features (build system):
- Create an optional relay module, which can be disabled using the
--disable-module-relay configure option. When it is set, also disable
the dirauth module. Add a minimal implemention, which disables the
relay and dircache modes in tor. Closes ticket 32123.
o Major features (controller):
- New ONION_CLIENT_AUTH_ADD control port command to add client-side onion
service client authorization credentials. Closes part of ticket 30381.
- New ONION_CLIENT_AUTH_REMOVE control port command to remove client-side
onion service client authorization credentials. Closes part of ticket
30381.
- New ONION_CLIENT_AUTH_VIEW control port command to view stored
client-side onion service client authorization credentials. Closes part
of ticket 30381.
o Major features (directory authority, ed25519):
Add support for banning a relay's ed25519 keys in the approved-routers
file. This will allow us to migrate away from RSA keys in the future.
Previously, only RSA keys could be banned in approved-routers. Resolves
ticket 22029. Patch by Neel Chauhan.
o Major features (documentation):
- Provide a Circuit Padding Framework quickstart guide and developer
documentation for researchers to implement and study Circuit Padding
machines. Closes ticket 28804.
o Major features (proxy):
- In addition to HTTP CONNECT, SOCKS4, and SOCKS5, Tor can make all OR
connections through the HAProxy server. A new torrc option was added to
specify the address/port of the server: TCPProxy <protocol>
<host>:<port>. Currently the only supported protocol in the option is
haproxy. Close ticket 31518. Patch done by Suphanat Chunhapanya (haxxpop).
o Major bugfixes (networking):
- Correctly handle IPv6 addresses in SOCKS5 RESOLVE_PTR requests,
and accept strings as well as binary addresses. Fixes bug 32315;
bugfix on 0.3.5.1-alpha.
o Major bugfixes (onion service):
- Report back HS circuit failure back into the HS subsytem so we take
appropriate action with regards to the client introduction point failure
cache. This improves reachability of onion services, since now clients
notice failing introduction circuits properly. Fixes bug 32020; bugfix on
0.3.2.1-alpha;
o Minor feature (configure, build system):
- Output enabled/disabled features at the end of the configure process in a
pleasing way. Closes ticket 31373.
o Minor feature (heartbeat, onion service):
- Add the DoS INTRODUCE2 defenses counter to the heartbeat DoS message.
Closes ticket 31371.
o Minor features (configuration validation):
- Configuration validation can now be done by per-module callbacks,
rather than a global validation function. This will let us reduce the
size of config.c and some of its more cumbersome functions. Closes
ticket 31241.
o Minor features (configuration):
- If the configured hardware crypto accelerator in AccelName
is prefixed with "!", Tor now exits when it cannot be found.
Closes ticket 32406.
- We use a flag-driven logic to warn about obsolete configuration fields,
so that we can include their names. In 0.4.2, we used
a special type, which prevented us from generating good warnings.
Implements ticket 32404.
o Minor features (continuous integration):
- Call the check_cocci_parse.sh script from Travis CI. Closes ticket 31919.
o Minor features (controller):
- Add stream isolation data to STREAM event. Closes ticket 19859.
- Implement a new GETINFO command to fetch microdescriptor consensus.
Closes ticket 31684.
o Minor features (debugging, directory system):
- Don't crash when we find a non-guard with a guard-fraction value set.
Instead, log a bug warning, in an attempt to figure out how this
happened. Diagnostic for ticket 32868.
o Minor features (defense in depth):
- Add additional sanity checks around tor_vasprintf() usage in case the
function returns an error. Patch by Tobias Stoeckmann. Fixes ticket 31147.
o Minor features (developer tooling):
- Remove 0.2.9 series branches from git scripts (git-merge-forward.sh,
git-pull-all.sh, git-push-all.sh, git-setup-dirs.sh). Closes ticket
32772.
o Minor features (developer tools):
- Add a check_cocci_parse.sh script that checks that new code
is parseable by Coccinelle. Add an exceptions file for unparseable
files. Closes ticket 31919.
- Add a rename_c_identifiers.py tool to rename a bunch of C
identifiers at once, and generate a well-formed commit message
describing the change. This should help with refactoring. Closes
ticket 32237.
- Add some scripts in "scripts/coccinelle" to invoke the Coccinelle
semantic patching tool with the correct flags. These flags are fairly
easy to forget, and these scripts should help us use Coccinelle more
effectively in the future. Closes ticket 31705.
- Call the check_cocci_parse.sh script from a 'check-cocci' Makefile
target. Closes ticket 31919.
o Minor features (disabling relay support):
- When Tor is compiled --disable-module-relay, we also omit the
code used to act as a directory cache. Closes ticket 32487.
o Minor features (documentation):
- Make sure that doxygen outputs documentation for all of our C files.
Previously, some were missing @file declarations, causing them to be
ignored. Closes ticket 32307.
o Minor features (Doxygen):
- Update Doxygen configuration file to a more recent template (from
1.8.15). Closes ticket 32110.
- "make doxygen" now works with out-of-tree builds. Closes ticket
32113.
- Our "make doxygen" target now respects --enable-fatal-warnings by
default, and does not warn about items that are missing documentation.
To warn about missing documentation, run configure with the
"--enable-missing-doc-warnings" flag: doing so suspends fatal warnings
for doxygen. Closes ticket 32385.
o Minor features (git scripts):
- Add TOR_EXTRA_CLONE_ARGS to git-setup-dirs.sh for git clone
customisation. Closes ticket 32347.
- Add TOR_EXTRA_REMOTE_* to git-setup-dirs.sh for a custom extra remote.
Closes ticket 32347.
- Add git-setup-dirs.sh, which sets up an upstream git repository and
worktrees for tor maintainers. Closes ticket 29603.
- Call the check_cocci_parse.sh script from the git commit and push hooks.
Closes ticket 31919.
- Make git-push-all.sh skip unchanged branches when pushing to upstream.
The script already skipped unchanged test branches.
Closes ticket 32216.
- Make git-setup-dirs.sh create a master symlink in the worktree directory.
Closes ticket 32347.
- Skip unmodified source files when doing some existing git hook checks.
Related to ticket 31919.
o Minor features (IPv6, client):
- Make Tor clients tell dual-stack exits that they prefer IPv6
connections. This change is equivalent to setting the PreferIPv6 flag
on SOCKSPorts (and most other listener ports). Tor Browser has been
setting this flag for some time, and we want to remove a client
distinguisher at exits. Closes ticket 32637.
o Minor features (portability, android):
- When building for Android, disable some tests that depend on
$HOME and/or pwdb, which Android doesn't have. Closes ticket 32825.
Patch from Hans-Christoph Steiner.
o Minor features (relay module):
- Split the relay and server pluggable transport config code into
separate files in the relay module. Disable this code when the relay
module is disabled. Closes ticket 32213.
- When the relay module is disabled, reject attempts to set the
ORPort, DirPort, DirCache, BridgeRelay, ExtORPort, or
ServerTransport* options, rather than ignoring the values of these
options. Closes ticket 32213.
o Minor features (relay):
- When the relay module is disabled, change the default config so that
DirCache is 0, and ClientOnly is 1. Closes ticket 32410.
o Minor features (release tools):
- Port our changelog formatting and sorting tools to Python 3.
Closes ticket 32704.
o Minor features (testing):
- Add common failure cases for test_parseconf.sh in
src/test/conf_failures. Closes ticket 32451.
- Allow test_parseconf.sh to test expected log outputs for successful
configs, as well as failed configs. Closes ticket 32451.
- test_parseconf.sh now supports result variants for any combination
of the optional libraries lzma, nss, and zstd.
Closes ticket 32397.
o Minor features (tests, Android):
- When running the unit tests on Android, create temporary files
in a subdirectory of /data/local/tmp. Closes ticket
32172. Based on a patch from Hans-Christoph Steiner.
o Minor bugfix (configuration):
- Check for multiplication overflow when parsing memory units inside
configuration. Fixes bug 30920; bugfix on 0.0.9rc1~46.
o Minor bugfixes (bridges):
- Lowercase the value of BridgeDistribution from torrc before adding it to
the descriptor. Fixes bug 32753; bugfix on 0.3.2.3-alpha.
o Minor bugfixes (build):
- Fix "make autostyle" for out-of-tree builds.
Fixes bug 32370; bugfix on 0.4.1.2-alpha.
o Minor bugfixes (config):
- When dumping the config, stop adding a trailing space after the option
name, when there is no option value. This issue only affects options
that accept an empty value or list. (Most options reject empty values,
or delete the entire line from the dumped options.)
Fixes bug 32352; bugfix on 0.0.9pre6.
o Minor bugfixes (configuration handling):
- Make control_event_conf_changed() take in a config_line_t instead of
a smartlist(k, v, k, v, ...) where keys are followed by values. Fixes
bug 31531; bugfix on 0.2.3.3-alpha. Patch by Neel Chauhan.
o Minor bugfixes (configuration):
- Avoid changing the user's value of HardwareAccel as stored by SAVECONF,
when AccelName is set but HardwareAccel is not.
Fixes bug 32382; bugfix on 0.2.2.1-alpha.
- When creating a KeyDirectory with the same location as the
DataDirectory (not recommended), respect the DataDirectory's
group-readable setting if one has not been set for the KeyDirectory.
Fixes bug 27992; bugfix on 0.3.3.1-alpha.
o Minor bugfixes (controller):
- In routerstatus_has_changed(), check all the fields that are output over the control port.
Fixes bug 20218; bugfix on 0.1.1.11-alpha
o Minor bugfixes (correctness checks):
- Use GCC/Clang's printf-checking feature to make sure that
tor_assertf() arguments are correctly typed. Fixes bug 32765;
bugfix on 0.4.1.1-alpha.
o Minor bugfixes (developer tools):
- Allow paths starting with ./ in scripts/add_c_file.py. Fixes bug
31336; bugfix on 0.4.1.2-alpha.
o Minor bugfixes (dirauth module):
- Split the dirauth config code into a separate file in the dirauth
module. Disable this code when the dirauth module is disabled.
Closes ticket 32213.
- When the dirauth module is disabled, reject attempts to set the
AuthoritativeDir option, rather than ignoring the value of the
option. Fixes bug 32213; bugfix on 0.3.4.1-alpha.
o Minor bugfixes (embedded Tor):
- When starting Tor any time after the first time in a process, register
the thread in which it is running as the main thread. Previously, we
only did this on Windows, which could lead to bugs like 23081 on
non-Windows platforms. Fixes bug 32884; bugfix on 0.3.3.1-alpha.
o Minor bugfixes (git scripts):
- Avoid sleeping before the last push in git-push-all.sh.
Closes ticket 32216.
- Forward all unrecognised arguments in git-push-all.sh to git push.
Closes ticket 32216.
o Minor bugfixes (hidden service v3):
- Do not rely on a "circuit established" flag for intro circuit but instead
always query the HS circuit map. This is to avoid sync issue with that
flag and the map. Fixes bug 32094; bugfix on 0.3.2.1-alpha.
o Minor bugfixes (linux seccomp sandbox):
- Correct how we use libseccomp. Particularly, stop assuming that
rules are applied in a particular order or that more rules are
processed after the first match. Neither is the case! In libseccomp
<2.4.0 this lead to some rules having no effect. Libseccomp 2.4.0
changed how rules are generated leading to a different ordering
which in turn lead to a fatal crash during startup. Fixes bug
29819; bugfix on 0.2.5.1-alpha. Patch by Peter Gerber.
- Fix crash when reloading logging configuration while the
experimental sandbox is enabled. Fixes bug 32841; bugfix
on 0.4.1.7. Patch by Peter Gerber.
o Minor bugfixes (logging, crash):
- Avoid a possible crash when trying to log a (fatal) assertion failure
about mismatched magic numbers in configuration objects. Fixes bug 32771;
bugfix on 0.4.2.1-alpha.
o Minor bugfixes (onion service v2):
- When sending the INTRO cell for a v2 Onion Service, look at the failure
cache alongside timeout values to check if the intro point is marked
as failed. Previously, we only looked at if the relay timeout values.
Fixes bug 25568; bugfix on 0.2.7.3-rc. Patch by Neel Chauhan.
o Minor bugfixes (onion services v3, client):
- Properly handle the client rendezvous circuit timeout. This results in
better reachability because tor doesn't timeout a rendezvous circuit
awaiting the introduction ACK and thus preventing tor to re-establish all
circuits because the rendezvous circuit timed out too early. Fixes bug
32021; bugfix on 0.3.2.1-alpha.
o Minor bugfixes (onion services):
- In cancel_descriptor_fetches(), use connection_list_by_type_purpose()
instead of connection_list_by_type_state(). Fixes bug 32639; bugfix on
0.3.2.1-alpha. Patch by Neel Chauhan.
o Minor bugfixes (scripts):
- Fix update_versions.py for out-of-tree builds.
Fixes bug 32371; bugfix on 0.4.0.1-alpha.
o Minor bugfixes (test):
- Use the same code to find the tor binary in all of our test scripts.
This change makes sure we are always using the coverage binary, when
coverage is enabled. Fixes bug 32368; bugfix on 0.2.7.3-rc.
o Minor bugfixes (testing):
- Stop ignoring "tor --dump-config" errors in test_parseconf.sh.
Fixes bug 32468; bugfix on 0.4.2.1-alpha.
- When TOR_DISABLE_PRACTRACKER is set, do not apply it to the
test_practracker.sh script. Doing so caused a test failure.
Fixes bug 32705; bugfix on 0.4.2.1-alpha.
- When TOR_DISABLE_PRACTRACKER is set, log a notice to stderr
when skipping practracker checks.
Fixes bug 32705; bugfix on 0.4.2.1-alpha.
o Minor bugfixes (tests):
- Our option-validation tests no longer depend on specially configured
non-default, non-passing set of options. Previously, the tests had
been written to assume that options would _not_ be set to their
defaults, which led to needless complexity and verbosity.
Fixes bug 32175; bugfix on 0.2.8.1-alpha.
o Minor bugfixes (windows service):
- Initialize publish/subscribe system when running as a windows service.
Fixes bug 32778; bugfix on 0.4.1.1-alpha.
o Code simplification and refactoring (channel):
- Channel layer had a variable length cell handler that was not used and
thus removed. Closes ticket 32892.
o Code simplification and refactoring (controller):
- Create a helper function that can fetch network status or microdesc
consensuses. Closes ticket 31684.
o Code simplification and refactoring:
- Add numerous missing dependencies to our include files, so that
they can be included in different reasonable orders and still
compile. Addresses part of ticket 32764.
- Create a new abstraction for formatting control protocol reply
lines based on key-value pairs. Refactor some existing control
protocol code to take advantage of this. Closes ticket 30984.
- Disable relay_periodic when the relay module is disabled.
Closes ticket 32244.
- Disable relay_sys when the relay module is disabled.
Closes ticket 32245.
- Fix some parts of our code that were difficult for Coccinelle to parse.
Related to ticket 31705.
- Fix some small issues in our code that prevented automatic
formatting tools from working.
Addresses part of ticket 32764.
- Immutability is now implemented as a flag on individual configuration
options rather than as part of the option-transition checking
code. Closes ticket 32344.
- Instead of keeping a list of configuration options to check for
relative paths, check all the options whose type is "FILENAME".
Solves part of ticket 32339.
- Make all the structs we declare follow the same naming convention
of ending with "_t". Closes ticket 32415.
- Move and rename some configuration-related code for clarity.
Closes ticket 32304.
- Our default log (which ordinarily sends NOTICE-level message to
standard output) is now handled in a more logical manner. Previously,
we replaced the configured log options if they were empty.
Now, we interpret an empty set of log options as meaning "use the
default log". Closes ticket 31999.
- Our include.am files are now broken up by subdirectory. Previously,
src/core/include.am covered all of the subdirectories in "core",
"feature", and "app". Closes ticket 32137.
- Remove some unused arguments from the options_validate() function,
to simplify our code and tests. Closes ticket 32187.
- Remove the last remaining HAVE_MODULE_DIRAUTH inside a function.
Closes ticket 32163.
- Remove underused NS*() macros from test code: they make our
tests more confusing, especially for code-formatting tools.
Closes ticket 32887.
- Replace some confusing identifiers in process_descs.c.
Closes ticket 29826.
- Simplify some relay and dirauth config code. Closes ticket 32213.
- Simplify the options_validate() code so that it looks at the default
options directly, rather than taking default options as an argument.
This change lets us simplify its interface. Closes ticket 32185.
- Use our new configuration architecture to move most authority-related
options to the directory authority module. Closes ticket 32806.
- When parsing the command line, handle options that determine our "quiet
level" and our mode of operation (e.g., --dump-config and so on)
all in one table. Closes ticket 32003.
o Deprecated features:
- Deprecate the ClientAutoIPv6ORPort option. This option was not true
Happy Eyeballs, and often failed on connections that weren't reliably
dual-stack. Closes ticket 32942. Patch by Neel Chauhan.
o Documentation (manpage):
- Alphabetize the Client Options section of the tor manpage.
Closes ticket 32846.
- Alphabetize the General Options section of the tor
manpage. Closes ticket 32708.
- In the tor(1) manpage, reword and improve formatting of the
COMMAND-LINE OPTIONS and DESCRIPTION sections. Closes ticket
32277. Based on work by Swati Thacker as part of Google Season
of Docs.
- In the tor(1) manpage, reword and improve formatting of the
FILES, SEE ALSO, and BUGS sections. Closes ticket 32176. Based
on work by Swati Thacker as part of Google Season of Docs.
o Documentation:
- Add documentation in 'HelpfulTools.md' to describe how to build a tag
file. Closes ticket 32779.
- Create a high-level description of the long-term software
architecture goals. Closes ticket 32206.
- Describe the --dump-config command in the manual page. Closes ticket
32467.
- Unite coding advice from this_not_that.md in torguts repo into our
coding standards document. Resolves ticket 31853.
o New system requirements:
- When building Tor, you now need to have Python 3 in order to
run the integration tests. (Python 2 is officially unsupported
upstream, as of 1 Jan 2020.) Closes ticket 32608.
o Removed features:
- Our Doxygen configuration no longer generates LaTeX output. The
reference manual produced by doing this was over 4000 pages long,
and generally unusable. Closes ticket 32099.
- The option "TestingEstimatedDescriptorPropagationTime" is now marked as
obsolete. It has had no effect since 0.3.0.7, when clients stopped
rejecting consensuses "from the future". Closes ticket 32807.
- We no longer support consensus methods before method 28; these
methods were only used by authorities running versions of Tor that
are now at end-of-life. In effect, this means that clients and
relays, and authorities now assume that authorities will be
running version 0.3.5.x or later. Closes ticket 32695.
o Testing (circuit, EWMA):
- Add unit tests for circuitmux and EWMA subsystems. Closes ticket 32196.
o Testing (continuous integration):
- Use zstd in our Travis Linux builds. Closes ticket 32242.
o Testing:
- Add more test cases for tor's UTF-8 validation function. Also, check the
arguments passed to the function for consistency.
Closes ticket 32845.
- Improve test coverage for relay and dirauth config code, focusing on
option validation and normalization. Closes ticket 32213.
- Improve the consistency of test_parseconf.sh output, and run all the
tests, even if one fails. Closes ticket 32213.
- Re-enable the Travis CI macOS Chutney build, but allow the job to finish
before it finishes, because the Travis macOS jobs are slow.
Closes ticket 32629.
- Run the practracker unit tests in the pre-commit git hook.
Closes ticket 32609.
- Turn off Tor's Sandbox in Chutney jobs, and run those jobs on Ubuntu
Bionic. Turning off the Sandbox is a work-around, until we fix the
sandbox errors in 32722. Closes ticket 32240.
