This commit adds a dedicated function in `EC_METHOD` to access a modular field inversion implementation suitable for the specifics of the implemented curve, featuring SCA countermeasures. The new pointer is defined as: `int (*field_inv)(const EC_GROUP*, BIGNUM *r, const BIGNUM *a, BN_CTX*)` and computes the multiplicative inverse of `a` in the underlying field, storing the result in `r`. Three implementations are included, each including specific SCA countermeasures: - `ec_GFp_simple_field_inv()`, featuring SCA hardening through blinding. - `ec_GFp_mont_field_inv()`, featuring SCA hardening through Fermat's Little Theorem (FLT) inversion. - `ec_GF2m_simple_field_inv()`, that uses `BN_GF2m_mod_inv()` which already features SCA hardening through blinding. From a security point of view, this also helps addressing a leakage previously affecting conversions from projective to affine coordinates. This commit also adds a new error reason code (i.e., `EC_R_CANNOT_INVERT`) to improve consistency between the three implementations as all of them could fail for the same reason but through different code paths resulting in inconsistent error stack states.

safestack.h, lhash.h and sparse_array.h all define macros to generate a full API for the containers as static inline functions. This potentially generates unused code, which some compilers may complain about. We therefore need to mark those generated functions as unused, so the compiler knows that we know, and stops complaining about it. Reviewed-by:

Add SSL_OP64_NO_EXTENDED_MASTER_SECRET, that can be set on either an SSL or an SSL_CTX. When processing a ClientHello, if this flag is set, do not indicate that the EMS TLS extension was received in either the ssl3 object or the SSL_SESSION. Retain most of the sanity checks between the previous and current session during session resumption, but weaken the check when the current SSL object is configured to not use EMS. Reviewed-by:

This makes `--strict-warnings` into a compiler pseudo-option, i.e. it gets treated the same way as any other compiler option given on the configuration command line, but is retroactively replaced by actual compiler warning options, depending on what compiler is used. This makes it easier to see in what order options are given to the compiler from the configuration command line, i.e. this: ./config -Wall --strict-warnings would give the compiler flags in the same order as they're given, i.e.: -Wall -Werror -Wno-whatever ... instead of what we got previously: -Werror -Wno-whatever ... -Wall Reviewed-by:

The "verify_return_error" option in s_client is documented as: Return verification errors instead of continuing. This will typically abort the handshake with a fatal error. In practice this option was ignored unless also accompanied with the "-verify" option. It's unclear what the original intention was. One fix could have been to change the documentation to match the actual behaviour. However it seems unecessarily complex and unexpected that you should need to have both options. Instead the fix implemented here is make the option match the documentation so that "-verify" is not also required. Note that s_server has a similar option where "-verify" (or "-Verify") is still required. This makes more sense because those options additionally request a certificate from the client. Without a certificate there is no possibility of a verification failing, and so "-verify_return_error" doing nothing seems ok. Fixes #8079 Reviewed-by:

The original 1.1.1 design was to use SSL_CB_HANDSHAKE_START and SSL_CB_HANDSHAKE_DONE to signal start/end of a post-handshake message exchange in TLSv1.3. Unfortunately experience has shown that this confuses some applications who mistake it for a TLSv1.2 renegotiation. This means that KeyUpdate messages are not handled properly. This commit removes the use of SSL_CB_HANDSHAKE_START and SSL_CB_HANDSHAKE_DONE to signal the start/end of a post-handshake message exchange. Individual post-handshake messages are still signalled in the normal way. This is a potentially breaking change if there are any applications already written that expect to see these TLSv1.3 events. However, without it, KeyUpdate is not currently usable for many applications. Fixes #8069 Reviewed-by:

There are times when one might want to use something like DEFINE_STACK_OF in a .c file, because it defines a stack for a type defined in that .c file. Unfortunately, when configuring with `--strict-warnings`, clang aggressively warn about unused functions in such cases, which forces the use of such DEFINE macros to header files. We therefore disable this warning from the `--strict-warnings` definition for clang. (note for the curious: `-Wunused-function` is enabled via `-Wall`) Reviewed-by:

This got triggered by test/testutil.h including ../apps/opt.h. Some compilers do all inclusions from the directory of the C file being compiled, so when a C file includes a header file with a relative file spec, and that header file also includes another header file with a relative file spec, the compiler no longer follows. As a specific example, test/testutil/basic_output.c included ../testutil.h. Fine so far, but then, test/testutil.h includes ../apps/opt.h, and the compiler ends up trying to include (seen from the source top) test/apps/opt.h rather than apps/opt.h, and fails. The solution could have been to simply add apps/ as an inclusion directory. However, that directory also has header files that have nothing to do with libapps, so we take this a bit further, create apps/include and move libapps specific headers there, and then add apps/include as inclusion directory in the build.info files where needed.

This change has us stop pretending anything else.
