iphydf 0c05566e58 cleanup: Further #include cleanups. 2024-01-31 21:04:53 +00:00
iphydf bdf460a3a9 refactor: Rename system_{memory,...} to os_{memory,...}. 
This rename happens in the system PR, so I'm pulling it out to reduce
the size of that PR.

iphydf 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.

iphydf 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.

iphydf 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.

iphydf cc31ff07fa feat: Add support for custom random number generator. 
This can be used by fuzzers to make RNG-driven code deterministic (i.e.
based on the fuzzer input).

iphydf 093927ba4f test: Add mallocfail and proxy test to our coverage runs. 2022-02-25 01:55:28 +00:00
iphydf 86a528a37a chore: Add a .clang-format that mostly agrees with astyle. 2022-02-21 16:16:16 +00:00
iphydf 6f36b67a13 chore: Add an undefined behaviour/integer sanitizer build. 2022-02-08 09:18:18 +00:00
iphydf 2570ddcb17 Fix errors on error paths found by oomer. 
* Use-after-free because we free network before dht in one case.
* Various unchecked allocs in tests (not so important).
* We used to not check whether ping arrays were actually allocated in DHT.
* `ping_kill` and `ping_array_kill` used to crash when passing NULL.

Also:
* Added an assert in all public API functions to ensure tox isn't NULL.
  The error message you get from that is a bit nicer than "Segmentation
  fault" when clients (or our tests) do things wrong.
* Decreased the sleep time in iterate_all_wait from 20ms to 5ms.
  Everything seems to still work with 5ms, and this greatly decreases
  the amount of time spent per test run, making oomer run much faster.

iphydf a1035cf814 Add some tests for ping_array. 
No timeout test here yet, because we don't yet have the ability to
manipulate time at will, so we would have to actually sleep.
