!!! WIP
This implements the "genec" layer wrapping mbedtls + openssl
ECDH support.
API tests are added for the parts that are implemented so far.
Stuff related to ec at all, like keys, are prefixed lws_genec_.
Stuff specific to ECDH are prefixed lws_genecdh_.
Until now the JOSE pieces only had enough support for ACME.
This patch improves the JWK parsing to prepare for more
complete support and for adding JWE, genaes and genec in
later patches.
Several new ops are planned for tls... so better to bite the bullet and
clean it out to the same level as roles + event-libs first.
Also adds a new travis target "mbedtls" and all the tests except
autobahn against mbedtls build.
1) Introduce LWS_WITH_GCOV to build with gcc / clang coverage instrumentation.
$ cd build
$ make clean && rm -f `find . -name "*.gcno" -o -name "*.gcda"` && make -j16 && sudo make install && sudo /usr/local/bin/libwebsockets-test-server -s
...
$ gcov `find . -name *.c.gcno | grep -v test-apps` -b | sed "/\.h.\$/,/^$/d"
The above are available in two helper scripts
- scripts/build-gcov.sh
- scripts/gcov.sh
2)
CMake defaults changed:
- LWS_WITH_ZIP_FOPS: OFF
- LWS_WITH_RANGES: OFF
- LWS_WITHOUT_EXTENSIONS: ON
- LWS_WITH_ZLIB: OFF
New CMake controls that default-OFF:
- LWS_WITH_GENHASH
- LWS_WITH_GENRSA
these are implied by LWS_WITH_JWS (which is implied by LWS_WITH_ACME)
3) rename ./lib/tls/XXX/server.c and client.c to XXX-server.c / XXX-client.c.
This is because gcov dumps its results using the .c filename part only,
the copies overwrite each other if there are different .c files in the tree
with the same filename part.
4) Add onetime test-client mode and test to ./test-apps/attack.sh
5) Add gcov howto in READMEs/README.build.md using attack.sh
