refactor: Remove Tox * from tox_dispatch.
...
User data can contain a tox instance if it needs to.

4359e3a6bc
chore: Rename C++ headers to .hh suffixes.
...
This helps formatters and other dump (simple) tools know what's C++ and
what's C.
2024-02-01 23:44:37 +00:00
bcb6592af5
test: Add C++ classes wrapping system interfaces.
...
These are more convenient and safer than the manual vtables we have in
the fuzzer support code. We can override individual member functions,
and C++ will take care of correctly casting and offsetting this-pointers
when needed.

fix: Make all the fuzzers work again, and add a test for protodump.
...
fuzz_select_target wasn't selecting anything, so fuzzers using that
function either did nothing or would only ever select one of the
functions.
2024-01-13 15:06:30 +00:00
812f931d5f
fix: Make sure there's enough space for CONSUME1 in fuzzers.
2024-01-12 14:52:35 +00:00
50f1b30fa9
test: Add fuzz tests to the coverage run.
...
So we don't need to write so many edge case tests ourselves for things
like parsers, which really don't need those manual tests, as long as we
can check for some properties like "can output the parsed data and it'll
be the same as the input".

cleanup: Some more test cleanups, removing overly smart code.
2024-01-10 12:42:37 +00:00
5cac6d7eb1
cleanup: Move tox_get_system out of the public API.
...
It's not released, yet, and this function is a pain. We don't want it
going forward.
2024-01-05 19:29:59 +00:00
c58928cc89
chore: Add IMPORTED_TARGET to pkg-config packages.
...
Also use `PRIVATE` for `target_link_libraries`. This helps avoid
implicit transitive dependencies.
2023-12-26 00:04:07 +00:00
7cfe35dff2
cleanup: Remove explicit layering_check feature.
...
It's default in .bazelrc now.
2023-11-23 23:55:57 +00:00
6be29f01e5
chore: Add more logging to loading conferences from savedata.
...
Better error messages than "something went wrong in type 20".
Also fix bazel-asan/tsan builds.
https://github.com/tweag/rules_nixpkgs/issues/442 is blocking fuzz
tests under asan.
2023-11-08 15:51:11 +00:00

cleanup: Fix GCC compatibility.
2023-11-07 12:18:22 +00:00
24b54722ae
fix: Ensure we have allocators available for the error paths.
2023-09-11 21:43:43 +00:00
a549807df7
refactor: Add mem module to allow tests to override allocators.
...
This will allow us to do more interesting things with memory allocation
within toxcore, and allow fuzzers to explore various allocation failure
paths.
2023-08-30 22:55:05 +00:00
7469a529b1
fix: Add missing #include <array>.
2023-08-15 20:47:27 +00:00
2e02d56379
chore: Add missing module dependencies.
...
Also flip some callback asserts, because they can be reached by fuzzing
eventually.
Also update the bootstrapd checksum, since the alpine image changed a
bit.
2023-08-10 21:01:17 +00:00

2022-12-04 18:52:09 +01:00

2022-04-19 23:42:47 +00:00
debedb3c94
test: Add a Null_System used in toxsave_harness.
...
This does nothing but has a working simple RNG.
2022-04-14 19:04:25 +00:00
19b9cf3812
test: Enable fuzzing for TCP.
...
If the `recvbuf` network function returns 0 all the time, that means
there is never any data available on the TCP socket. This change makes
it so there is a random amount of data available on the TCP socket.
This invalidates the bootstrap fuzzer corpus.
2022-04-14 13:19:56 +00:00
d78ee9b12e
fix: Fix potential array out-of-bounds in DHT random node retrieval.
...
It can't happen in almost every reality, except when the RNG is fairly
broken and doesn't add 2 fake DHT friends on startup. Still, this code
should be defensive and never index outside `num_friends` elements.
2022-04-10 23:17:15 +00:00
60b71adbfa
test: Don't abort fuzz test when tox_new fails.
...
Right now, it can't fail, but later we want the fuzzer to randomly let
I/O functions fail, so we shouldn't assert tox_new succeeded.
2022-04-10 22:35:00 +00:00
27c27b7c8c
refactor: Avoid static_cast in Fuzz_System functions.
...
Declutters the fuzz system code a bit, hiding the cast behind a `!`
operator.

Downgrade C++ version to 17
2022-04-10 12:44:04 -04:00
cb34fe12d1
test: Add more functionality to the bootstrap harness.
...
Ideally this would be able to reach some of the events, so we can write
code to respond to those events, but so far only the friend request
event actually happens.
2022-04-07 20:17:56 +00:00
941026266e
refactor: Allow overriding mono_time in tox_new.
...
This makes it so if mono_time is overridden, no monotonic time-related
system call is invoked in tox_new.
2022-04-03 22:48:16 +00:00
dec1399776
test: Add fuzzer support functions for internal toxcore objects.
...
These help creating fuzzer fixtures with non-trivially constructed
objects and takes care of cleaning them up afterwards so the fuzzer code
can focus on the system under test.
2022-04-03 11:21:06 +00:00

try to save the fuzzed save file again

This should test some additional code paths.
2022-03-26 14:09:04 +01:00

test: Add fuzzer tests to the bazel build.
2022-03-25 18:48:41 +00:00

intercept network, crypto and time
...
This fuzzing harness must be as deterministic as possible for the fuzzer
to detect additional coverage reliably.
2022-01-10 21:05:49 +01:00
9eb88798a3
add fuzzing harnesses
...
Toxsave harness ported to libFuzzer interface.
