This changes the API of xfa from
XFA(array_name, prio) type element_name = INITIALIZER;
to
XFA(type, array_name, prio) element_name = INITIALIZER;
this allows forcing natural alignment of the type, fixing failing tests
on `native64`.
This increases test coverage for coap_build_reply_header() for the case
that extended tokens are used. The test validates the correctness of
the return value and the correctness of the assembled reply.
Previously the corner case when RFC 8974 extended TKL fields are used
the result of coap_get_totel_hdr_len() was not tested, resulting in a
bug slipping through the test. This increase the test coverage.
This has the following advantages:
- faster and leaner when C11 atomics are not efficient (e.g. on LLVM
this is almost always the case, as LLVM will only use efficient
atomics if it doesn't has to bail out to library calls even for
exotic things)
- Even for GCC e.g. on the nucleo-f429zi this safes 72 B of .text
for examples/filesystem despite runtime checks added for
over- and underflow
- less pain in the ass for C++ and rust users, as both C++ and
c2rust are incompatible with C11 atomics
- adds test for overflow of the open file counter for more robust
operation
- adds `assumes()` so that underflows are detected in non-production
code
This commit changes the link about supported boards in the README from the wiki page to the RIOT-OS website.
Since the wiki is not up to date.
See also [this pull request](https://github.com/RIOT-OS/riot-os.org/pull/109/files) that fixed the same link on the website.
This patch adds calls to be able to peek at items other than just the
oldest item in a cib based FIFO. It also adds an "unsafe" peek to match
the existing "unsafe" put and get functions.
The constants BIG_ENDIAN etc. were not consistently defined. This
bug was not caught by the unit tests, as the preprocessor would
treat undefined macros as being `0` in numeric comparisons, hence
the following test did select the correct implementation:
```C
#if BYTE_ORDER == LITTLE_ENDIAN
/* correct implementation for all currently supported boards */
#endif
```
This adds now an explicit test to the unit tests to ensure that the
magic numbers are consistently the correct values. Hence, this bug
should no longer be able to sneak in.

Reverts the type changes for the array size variables, as `size_t` is needed
in the function calls `fib_get_next_hop` and `fib_get_destination_set`.
Fixes 475a55136a
The CC2538-CC2592-DK is one of the few readily available and
affordable boards featuring a legacy CC2538 MCU. This should make
maintaining RIOT support for that legacy MCU more affordable :-)
