* New interfaces:
- New cipher mode XTS
- New hash function Blake-2
- New function gcry_mpi_point_copy.
- New function gcry_get_config.
- GCRYCTL_REINIT_SYSCALL_CLAMP allows to init nPth after Libgcrypt.
- New gobal configuration file /etc/gcrypt/random.conf.
* Extended interfaces:
- GCRYCTL_PRINT_CONFIG does now also print build information for
libgpg-error and the used compiler version.
- GCRY_CIPHER_MODE_CFB8 is now supported.
- Add Stribog OIDs.
* Performance:
- A jitter based entropy collector is now used in addition to the
other entropy collectors.
- Optimized gcry_md_hash_buffers for SHA-256 and SHA-512.
- More ARMv8/AArch32 improvements for AES, GCM, SHA-256, and SHA-1.
- Add ARMv8/AArch32 assembly implementation for Twofish and
Camellia.
- Add bulk processing implementation for ARMv8/AArch32.
- Improve the DRBG performance and sync the code with the Linux
version.
* Internal changes:
- Libgpg-error 1.25 is now required. This avoids stalling of nPth
threads due to contention on internal Libgcrypt locks (e.g. the
random pool lock).
- The system call clamp of libgpg-error is now used to wrap the
blocking read of /dev/random. This allows other nPth threads to
run while Libgcrypt is gathering entropy.
- When secure memory is requested by the MPI functions or by
gcry_xmalloc_secure, they do not anymore lead to a fatal error if
the secure memory pool is used up. Instead new pools are
allocated as needed. These new pools are not protected against
being swapped out (mlock can't be used). However, these days
this is considered a minor issue and can easily be mitigated by
using encrypted swap space.
* Bug fixes:
- Fix AES CTR self-check detected failure in the SSSE3 based
implementation.
- Remove gratuitous select before the getrandom syscall.
- Fix regression in mlock detection.
- Fix GOST 28147 CryptoPro-B S-box.
- Fix error code handling of mlock calls.
- Fix possible timing attack on EdDSA session key.
- Fix long standing bug in secure memory implementation which could
lead to a segv on free.
- Mitigate a flush+reload side-channel attack on RSA secret keys
dubbed "Sliding right into disaster".
