This is a fairly easy way for us to get our test coverage up on
compat_threads.c and workqueue.c -- I already implemented these
tests, so we might as well enable them.
We know there are overflows in curve25519-donna-c32, so we'll have
to have that one be fwrapv.
Only apply the asan, ubsan, and trapv options to the code that does
not need to run in constant time. Those options introduce branches
to the code they instrument.
(These introduced branches should never actually be taken, so it
might _still_ be constant time after all, but branch predictors are
complicated enough that I'm not really confident here. Let's aim for
safety.)
Closes 17983.
The goal here is to provide a way to decouple pieces of the code
that want to learn "when something happens" from those that realize
that it has happened.
The implementation here consists of a generic backend, plus a set of
macros to define and implement a set of type-safe frontends.
* DIGEST_SHA3_[256,512] added as supported algorithms, which do
exactly what is said on the tin.
* test/bench now benchmarks all of the supported digest algorithms,
so it's possible to see just how slow SHA-3 is, though the message
sizes could probably use tweaking since this is very dependent on
the message size vs the SHA-3 rate.
Using variables removes the ambiguity about when to use variables and
when to use substitutions. Variables always work. Substitutions only
work when Autoconf knows about them which is not always the case.
The variables are also placed between quotes to ensures spaces in the
variables are handled properly.
Use environment variables instead. This repairs 'make distcheck',
which was running into trouble when it tried to chmod the generated
scripts.
Fixes 17148.
make test-network-all is Makefile target which verifies a series
of test networks generated using test-network.sh and chutney.
It runs IPv6 and mixed version test networks if the prerequisites are
available.
Each test network reports PASS, FAIL, or SKIP.
Closes ticket 16953. Patch by "teor".
Also adds "--hs-multi-client 1" option to TEST_NETWORK_FLAGS.
This resolves#17012.
Larger networks, such as bridges+hs, may fail until #16952 is merged.
An earlier version of these tests was broken; now they're a nicer,
more robust, more black-box set of tests. The key is to have each
test check a handshake message that is wrong in _one_ way.
This module implements a key-pinning mechanism to ensure that it's
safe to use RSA keys as identitifers even as we migrate to Ed25519
keys. It remembers, for every Ed25519 key we've seen, what the
associated Ed25519 key is. This way, if we see a different Ed25519
key with that RSA key, we'll know that there's a mismatch.
We persist these entries to disk using a simple format, where each
line has a base64-encoded RSA SHA1 hash, then a base64-endoded
Ed25519 key. Empty lines, misformed lines, and lines beginning with
a # are ignored. Lines beginning with @ are reserved for future
extensions.
For prop220, we have a new ed25519 certificate type. This patch
implements the code to create, parse, and validate those, along with
code for routers to maintain their own sets of certificates and
keys. (Some parts of master identity key encryption are done, but
the implementation of that isn't finished)
These commands allow for the creation and management of ephemeral
Onion ("Hidden") services that are either bound to the lifetime of
the originating control connection, or optionally the lifetime of
the tor instance.
Implements #6411.
The SH_LOG_COMPILER feature doesn't work with older automakes, and
those are still in use in many environments we want to support
development on, like Debian Stable.
Instead, use autoconf substitution to fill out the shebang lines on
the shell scripts, and an intermediate make target to make them
executable.
This is a bugfix on the patches for #15344. Bug not in any released
tor.
For this to work bt_test.py now returns an exit code indicating success or
failure. Additionally, check-local and its specific dependencies are now
obsolete so they are removed.
The zero length keys test now requires the path to the Tor binary as the first
parameter to ensure the correct Tor binary is used without hard coding a path.
The wrapper script calls the zero length keys test for each test separately to
ensure the correct shell is used (as configured by autoconf). Another solution
would have been to place the tests into separate functions so multiple tests
could be run internally. This would have made a diff of considerable size and
frankly it is outside the scope of this fix.
It invokes undefined behavior, I'm afraid, since there's no other
c-legal way to test whether memwipe() works when we're not allowed to
look at it.
Closes ticket 15377.
Before a couple weeks ago didn't know Tor had these tests, interesting! Stem
already has tests for spawning tor processes but lacked any with this targeted
focus on its arguments.
I've added our own counterpart for these tests. Many are direct copies but
there were others I improved a little...
https://trac.torproject.org/projects/tor/ticket/14109https://gitweb.torproject.org/stem.git/commit/?id=137d193a026638f066e817e3396cebbbb6ace012
Now that Tor uses Stem to supplement its tests no reason for these to live
separately. Tested by simply building tor and confirming test_cmdline_args.py
is no longer in the generated Makefile.
Check that tor generates new keys, and overwrites the empty key files.
Test that tor generates new keys when keys are missing (existing
behaviour).
Test that tor does not overwrite key files that already contain data
(existing behaviour).
Tests fixes to bug 13111.
By now, support in the network is widespread and it's time to require
more modern crypto on all Tor instances, whether they're clients or
servers. By doing this early in 0.2.6, we can be sure that at some point
all clients will have reasonable support.
We didn't really have test coverage for these parsing functions, so
I went and made some. These tests also verify that the parsing
functions set the list of invalid digests correctly.
Also, use it to generate test vectors, and add those test vectors
to test_crypto.c
This is based on ed25519.py from the ed25519 webpage; the kludgy hacks
are my own.
This reduces the likelihood that I have made any exploitable errors
in the encoding/decoding.
This commit also imports the trunnel runtime source into Tor.
A new set of unit test cases are provided, as well as introducing
an alternative paradigm and macros to support it. Primarily, each test
case is given its own namespace, in order to isolate tests from each
other. We do this by in the usual fashion, by appending module and
submodule names to our symbols. New macros assist by reducing friction
for this and other tasks, like overriding a function in the global
namespace with one in the current namespace, or declaring integer
variables to assist tracking how many times a mock has been called.
A set of tests for a small-scale module has been included in this
commit, in order to highlight how the paradigm can be used. This
suite gives 100% coverage to status.c in test execution.
No other changes were made here. Keeping everything in
src/test/test.c was a legacy of back when we had all our unit tests in
one big file.
Doing this now because I'm adding an ext_or_command test.
I added this so I could write a unit test for ServerTransportOptions,
but it incidentally exercises the succeed-on-defaults case of
options_validate too.
If you pass the --enable-coverage flag on the command line, we build
our testing binaries with appropriate options eo enable coverage
testing. We also build a "tor-cov" binary that has coverage enabled,
for integration tests.
On recent OSX versions, test coverage only works with clang, not gcc.
So we warn about that.
Also add a contrib/coverage script to actually run gcov with the
appropriate options to generate useful .gcov files. (Thanks to
automake, the .o files will not have the names that gcov expects to
find.)
Also, remove generated gcda and gcno files on clean.
This is mainly a matter of automake trickery: we build each static
library in two versions now: one with the TOR_UNIT_TESTS macro
defined, and one without. When TOR_UNIT_TESTS is defined, we can
enable mocking and expose more functions. When it's not defined, we
can lock the binary down more.
The alternatives would be to have alternate build modes: a "testing
configuration" for building the libraries with test support, and a
"production configuration" for building them without. I don't favor
that approach, since I think it would mean more people runnning
binaries build for testing, or more people not running unit tests.
