This removes a preliminar dependency resolution that is performed
without including features, to skip a full dependency resolution when
boards can be proven to be unsupported on an earlier stage.
This was introducing issues on some boards since the blacklisting of
some features depends on board information which is not available at the
time of performing this resolution.
When using eval the function board_unsatisfied_features is evaluated
twice, in the first evaluation this will lead to the previous value
for `BOARDS` to be expanded, so escape all occurrences.
Instead of making a NETTYPE definition dependent on an implementation
module, this change makes it dependent on a pseudo-module for each
specific NETTYPE and makes the respective implementation modules
dependent on it.
This has two advantages:
- one does not need include the whole implementation module to
subscribe to a NETTYPE for testing or to provide an alternative
implementation
- A lot of circular dependencies related to GNRC could be untangled.
E.g. the only reason `gnrc_icmpv6` needs the `gnrc_ipv6` is because it
uses `GNRC_NETTYPE_IPV6` to search for the IPv6 header in an ICMPv6
when demultiplexing an ICMPv6 header.
This change does not resolve these dependencies or include usages where
needed. The only dependency change is the addition of the
pseudo-modules to the implementation modules.
- Add the new EXTERNAL_BOARD_DIRS variable that can contain a space separated
list of folders containing external boards
- Introduce $(BOARDDIR) as shortcut for $(BOARDSDIR)/$(BOARD)
- Map the existing BOARDSDIR to the new approach
- If BOARDSDIR is provided by the user, it will be added to
EXTERNAL_BOARD_DIRS for backward compatibility. (And a warning is issued
to encourage users migrating to EXTRA_BOARDS.)
- BOARDSDIR is updated after the board is found to "$(BOARDDIR)/..".
- Useful for `include $(BOARDSDIR)/common/external_common/Makefile.dep`
- Provides backward compatibility
This adds a new subdirectory called `fuzzing/` which will contain
applications for fuzzing various RIOT network modules in the future.
This subdirectory is heavily inspired by the `examples/` subdirectory.
The fuzzing applications use AFL as a fuzzer. Each application contains
Makefiles, source code, and an input corpus used by AFL to generate
input for fuzzing.
Enabled by the gnrc_netif_events pseudo module. Using an internal event
loop within the gnrc_netif thread eliminates the risk of lost interrupts
and lets ISR events always be handled before any send/receive requests
from other threads are processed.
The events in the event loop is also a potential hook for MAC layers and
other link layer modules which may need to inject and process events
before any external IPC messages are handled.

With #10970 only existing *.c files will be added to SRC when using
the SUBMODULES mechanism, so SUBMODULES_NOFORCE (used to filter out
non existing source files) is now redundant so remove the usage.
'merged.config' may not always be present (e.g. when no files to merge
are present). In order to always have an up-to-date configuration file
'out.config' will be generated mirroring the content of 'autoconf.h'.
This is the file that the build system will include to read the current
configuration symbols.
