When I wrote the first one of these, it needed the path of the geoip
file. But that doesn't translate well in at least two cases:
- Mingw, where the compile-time path is /c/foo/bar and the
run-time path is c:\foo\bar.
- Various CI weirdnesses, where we cross-compile a test binary,
then copy it into limbo and expect it to work.
Together, these problems precluded these tests running on windows.
So, instead let's just generate some minimal files ourselves, and
test against them.
Fixes bug 25787
We had accumulated a bunch of cruft here. Now let's only include
src and src/ext. (exception: src/trunnel is autogenerated code, and
need to include src/trunnel.)
This commit will break the build hard. The next commit will fix it.
We need this trick because some of our Rust tests depend on our C
code, which in turn depend on other native libraries, which thereby
pulls a whole mess of our build system into "cargo test".
To solve this, we add a build script (build.rs) to set most of the
options that we want based on the contents of config.rust. Some
options can't be set, and need to go to the linker directly: we use
a linker replacement (link_rust.sh) for these. Both config.rust and
link_rust.sh are generated by autoconf for us.
This patch on its own should enough to make the crypto test build,
but not necessarily enough to make it pass.
Also make sure that we're actually running the test from within the right
cwd, like we do when we're building. This seems necessary to avoid
an error when running offline.
Amusingly, it appears that we had this bug before: we just weren't
noticing it, because of bug 26258.
This functionality was covered only accidentally by our voting-test
code, and as such wasn't actually tested at all. The tests that
called it made its coverage nondeterministic, depending on what time
of day you ran the tests.
Closes ticket 26014.
Needed to run tests from the tarball else the geoip unit test would fail by
not finding that file.

This differs from our previous token bucket abstraction in a few
ways:
1) It is an abstraction, and not a collection of fields.
2) It is meant to be used with monotonic timestamps, which should
produce better results than calling gettimeofday over and over.
This roughly doubles our test coverage of the bridges.c module.
* ADD new testing module, .../src/test/test_bridges.c.
* CHANGE a few function declarations from `static` to `STATIC`.
* CHANGE one function in transports.c, transport_get_by_name(), to be
mockable.

These tests handle incoming and outgoing cells on a three-hop
circuit, and make sure that the crypto works end-to-end. They don't
yet test spec conformance, leaky-pipe, or various error cases.
This introduces the test_hs_control.c file which at this commit contains basic
unit test for the HS_DESC event.

When running "make test-network-all", test that IPv6-only clients can use
microdescriptors. IPv6-only microdescriptor client support was fixed in
tor 0.3.0.1-alpha.
Requires chutney master 61c28b9 or later.
Closes ticket 24109.
Using a test vector in python, test both hs_build_hsdir_index() and
hs_build_hs_index().
This commit also adds the hs_build_address.py to EXTRA_DIST which was missing.

This adds a couple of configure commands to control whether we're
requiring all dependencies to be available locally (default) or not
(--enable-cargo-online-mode). When building from a tarball, we require
the RUST_DEPENDENCIES variable to point to the local repository of
crates. This also adds src/ext/rust as a git submodule that contains
such a local repository for easy setup.
Passing --enable-cargo-online-mode during configure allows cargo to make
network requests while building Tor or running tests. If this flag is
not supplied, the dependencies need to be available in the form of a
local mirror.
This gives an indication in the log that Tor was built with Rust
support, as well as laying some groundwork for further string-returning
APIs to be converted to Rust
Create the hs_test_helpers.{c|h} files that contains helper functions to
create introduction point, descriptor and compare descriptor.
Used by both the hs cache and hs descriptor tests. Unify them to avoid code
duplication.
Also, this commit fixes the usage of the signing key that was wrongly used
when creating a cross signed certificate.

This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.
Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.
The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.
The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.
Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.
Introduce a way to optionally enable Rust integration for our builds. No
actual Rust code is added yet and specifying the flag has no effect
other than failing the build if rustc and cargo are unavailable.
This commit adds the src/trace directory containing the basics for our tracing
subsystem. It is not used in the code base. The "src/trace/debug.h" file
contains an example on how we can map our tor trace events to log_debug().
The tracing subsystem can only be enabled by tracing framework at compile
time. This commit introduces the "--enable-tracing-debug" option that will
make all "tor_trace()" function be maped to "log_debug()".
Closes#13802

This patch adds support for enabling support for Zstandard to our configure
script. By default, the --enable-zstd option is set to "auto" which means if
libzstd is available we'll build Tor with Zstandard support.
See: https://bugs.torproject.org/21662
This patch adds support for enabling support for LZMA to our configure
script. By default, the --enable-lzma option is set to "auto" which
means if liblzma is available we'll build Tor with LZMA support.

Initial tests. These just try adding a few consensuses, looking
them up, and making sure that consensus diffs are generated in a
more or less reasonable-looking way. It's enough for 87% coverage,
but it leaves out a lot of functionality.
We could use one of these for holding "junk" descriptors and
unparseable things -- but we'll _need_ it for having cached
consensuses and diffs between them.
(This commit was extracted by nickm based on the final outcome of
the project, taking only the changes in the files touched by this
commit from the consdiff_rebased branch. The directory-system
changes are going to get worked on separately.)
