build: Use the new build system for fuzz tests Signed-off-by: Johannes Berg <johannes.berg@intel.com> 2020-10-11 09:58:57 +02:00			`FUZZ_RULES := $(lastword $(MAKEFILE_LIST))`

tests: Fix CFLAGS passing for new fuzzing tools src/*/Makefile needs to allow additional CFLAGS values to be provided from the calling Makefiles so that the clang command line arguments to enable sanitizers consistently. In addition, it can be useful to be able to provide CC, CFLAGS, and LDFLAGS from external setup while still requesing LIBFUZZER=y build. Allow that by not overriding these variables if they are already set. Signed-off-by: Jouni Malinen <jouni@codeaurora.org> 2019-06-07 22:57:02 +02:00			`FUZZ_CFLAGS =`

tests: New style fuzzing tool for wpa_supplicant WNM handling This is a newer version of tests/wnm-fuzzer tool as the initial step in creating a more uniform set of fuzzing tools that can be used with both libFuzzer and afl-fuzz.

build: Put archive files into build/ folder too This is something I hadn't previously done, but there are cases where it's needed, e.g., building 'wlantest' and then one of the tests/fuzzing/*/ projects, they use a different configuration (fuzzing vs. not fuzzing). Perhaps more importantly, this gets rid of the last thing that was dumped into the source directories, apart from the binaries themselves. Note that due to the use of thin archives, this required building with absolute paths. Signed-off-by: Johannes Berg <johannes.berg@intel.com> 2020-10-11 09:58:58 +02:00			`# for the lib builds`
