The EFD database does not state that the "ladd-2002-it-3" algorithm assumes X1 != 0. Consequently the current implementation, based on it, fails to compute correctly if the affine x coordinate of the scalar multiplication input point is 0. We replace this implementation using the alternative algorithm based on Eq. (9) and (10) from the same paper, which being derived from the additive relation of (6) does not incur in this problem, but costs one extra field multiplication. The EFD entry for this algorithm is at https://hyperelliptic.org/EFD/g1p/auto-shortw-xz.html#ladder-ladd-2002-it-4 and the code to implement it was generated with tooling. Regression tests add one positive test for each named curve that has such a point. The `SharedSecret` was generated independently from the OpenSSL codebase with sage. This bug was originally reported by Dmitry Belyavsky on the openssl-users maling list: https://mta.openssl.org/pipermail/openssl-users/2018-August/008540.html Co-authored-by:

Having post handshake auth automatically switched on breaks some applications written for TLSv1.2. This changes things so that an explicit function call is required for a client to indicate support for post-handshake auth. Fixes #6933. Reviewed-by:

CRYPTO_atomic_read was added with intention to read statistics counters, but readings are effectively indistinguishable from regular load (even in non-lock-free case). This is because you can get out-dated value in both cases. CRYPTO_atomic_write was added for symmetry and was never used. Reviewed-by:

Extra slashes in paths are permissible in Unix-like platforms... however, when compared with the result from 'which', which returns canonical paths, the comparison might fail even though the compared paths may be equivalent.

Since 0.9.7, all i2d_ functions were documented to allocate an output buffer if the user didn't provide one, under these conditions (from the 1.0.2 documentation): For OpenSSL 0.9.7 and later if B<*out> is B<NULL> memory will be allocated for a buffer and the encoded data written to it. In this case B<*out> is not incremented and it points to the start of the data just written. i2d_ASN1_OBJECT was found not to do this, and would crash if a NULL output buffer was provided.

If we sent early_data and then received back an HRR, the enc_write_ctx was stale resulting in errors if an alert needed to be sent. Thanks to Quarkslab for reporting this. In any case it makes little sense to encrypt alerts using the client_early_traffic_secret, so we add special handling for alerts sent after early_data. All such alerts are sent in plaintext.
