Move the common plugin scanning dir stuff to be based on lws_dir, which
already builds for windows. Previously this was done via dirent for unix
and libuv for windows.
Reduce the dl plat stuff to just wrap instantiation and destruction of
dynlibs, establish common code in lib/misc/dir.c for plugin scanning
itself.
Migrate the libuv windows dl stuff to windows-plugins.c, so that he's
available even if later libuv loop support becomes and event lib plugin.
Remove the existing api exports scheme for plugins, just export a const struct
now which has a fixed header type but then whatever you want afterwards depending
on the class / purpose of the plugin. Place a "class" string in the header so
there can be different kinds of plugins implying different types exported.
Make the plugin apis public and add support for filter by class string, and
per instantation / destruction callbacks so the subclassed header type can
do its thing for the plugin class. The user provides a linked-list base
for his class of plugins, so he can manage them completely separately and
in user code / user export types.
Rip out some last hangers-on from generic sessions / tables.
This is all aimed at making the plugins support general enough so it can
provide event lib plugins later.
!!! 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_.
Although RSA can be used directly for signing / JWS
on large chunks of data since it's only operating on
the hash, when JWE support arrives, which allows bulk
encryption, it's going to be mandatory to support
secondary AES ciphers to use on the bulk data.
This adds generic support for all AES modes that OpenSSL
and mbedTLS have in common, works on both mbedTLS and
OpenSSL the same, and adds unit tests for each mode
in api-test-gencrypto, to run in CI.
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.
This enables selected things from -Wextra, can't use -Wextra because it is
fussy enough to complain about unused params on functions... they are
there for a reason.
-Wsign-compare
-Wignored-qualifiers
not -Wimplicit-fallthrough=3 ... only on gcc 7
-Wtype-limits
-Wuninitialized
not -Wclobbered ... only on gcc 7ish
fix the warnings everywhere they were found.
- introduce lib/tls/mbedtls lib/tls/openssl
- move wrapper into lib/tls/mbedtls/wrapper
- introduce private helpers to hide backend
This patch doesn't replace or remove the wrapper, it moves it
to lib/tls/mbedtls/wrapper.
But it should be now that the ONLY functions directly consuming
wrapper apis are isolated in
- lib/tls/mbedtls/client.c (180 lines)
- lib/tls/mbedtls/server.c (317 lines)
- lib/tls/mbedtls/ssl.c (325 lines)
In particular there are no uses of openssl or mbedtls-related
constants outside of ./lib/tls any more.
Almost all the CMake options begin with LWS_WITH_..., but many of the
symbols passed to lws are LWS_USE_... , this causes neededless confusion,
compounded by the fact that a few CMake options also begin with
LWS_USE_.
This patch globally converts all LWS_USE_... to LWS_WITH_..., so there
is only one prefix to remember in both CMake and the code.
The affected public CMake options are
LWS_USE_BORINGSSL -> LWS_WITH_BORINGSSL
LWS_USE_CYASSL -> LWS_WITH_CYASSL
LWS_USE_WOLFSSL -> LWS_WITH_WOLFSSL
LWS_USE_MBEDTLS -> LWS_WITH_MBEDTLS
LWS_USE_BUNDLED_ZLIB -> LWS_WITH_BUNDLED_ZLIB
