We have a more portable wrapper that is now also thread-safe. Also
stopped using sprintf in the one place we used it. This doesn't really
help much, but it allows us to forbid sprintf globally.
Currently: 1) libsodium and 2) nacl.
Note that the "nacl" variant is actually libsodium. We just want to make
sure the static analysers see the `VANILLA_NACL` code paths.
Also added a valgrind build to run it on every pull request. I've had to
disable a few tests because valgrind makes those run infinitely slowly,
consistently timing them out.
Apidsl is not powerful enough to express all the things we need and
doesn't know how `#include` works. The generated headers are more complex
than they should be.
This aligns the autotools build with the cmake build, which doesn't have
a config.h file. It also removes the ambiguity of config.h and
other/bootstrap_daemon/src/config.h.
We used to have lots of these in the code, but now that all the endian
stuff is no longer dependent on host byte order, we can re-enable the
warning flag and catch any future violations.
The test explicitly wanted a UDP connection when a TCP connection would suffice. This
was a remnant of back when the test was part of a multi-purpose autotest that
didn't attempt to connect to TCP relays and needed a UDP connection specifically.
* 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.
This allows invitations to work in the case that the invitee is already
in the group, which can happen if the group becomes split. Such an
invitation is automatically accepted, leading to the peers becoming
connected in the group and sharing peer lists.
The test's intermittent failure may well be exposing a real bug in the
TCP relay and/or onion systems, but we can't find the bug, and keeping
the test is disrupting our CI.
Also added and used the new crypto_malloc and crypto_free.
The latter also zeroes out the memory safely. The former only exists for
symmetry (static analysis can detect asymmetric usages).
