Changes between 1.1.1r and 1.1.1s [1 Nov 2022]
*) Fixed a regression introduced in 1.1.1r version not refreshing the
certificate data to be signed before signing the certificate.

Changes between 1.1.1q and 1.1.1r [11 Oct 2022]
*) Fixed the linux-mips64 Configure target which was missing the
SIXTY_FOUR_BIT bn_ops flag. This was causing heap corruption on that
platform.
[Adam Joseph]
*) Fixed a strict aliasing problem in bn_nist. Clang-14 optimisation was
causing incorrect results in some cases as a result.
[Paul Dale]
*) Fixed SSL_pending() and SSL_has_pending() with DTLS which were failing to
report correct results in some cases
[Matt Caswell]
*) Fixed a regression introduced in 1.1.1o for re-signing certificates with
different key sizes
[Todd Short]
*) Added the loongarch64 target
[Shi Pujin]
*) Fixed a DRBG seed propagation thread safety issue
[Bernd Edlinger]
*) Fixed a memory leak in tls13_generate_secret
[Bernd Edlinger]
*) Fixed reported performance degradation on aarch64. Restored the
implementation prior to commit 2621751 ("aes/asm/aesv8-armx.pl: avoid
32-bit lane assignment in CTR mode") for 64bit targets only, since it is
reportedly 2-17% slower and the silicon errata only affects 32bit targets.
The new algorithm is still used for 32 bit targets.
[Bernd Edlinger]
*) Added a missing header for memcmp that caused compilation failure on some
platforms

Subject: Add OPENSSL_PREFER_CHACHA_OVER_GCM option
|
|
|
|
This enables a compile-time option to prefer ChaCha20-Poly1305 over
|
|
AES-GCM in the openssl default ciphersuite, which is useful in systems
|
|
without AES specific CPU instructions.
|
|
OPENSSL_PREFER_CHACHA_OVER_GCM must be defined to enable it.
|
|
|
|
Note that this does not have the same effect as the
|
|
SL_OP_PRIORITIZE_CHACHA option, which prioritizes ChaCha20-Poly1305 only
|
|
when the client has it on top of its ciphersuite preference.
