Notes
Title of the patch: Feature update for libgcrypt, libgpg-error
Description of the patch: This update for libgcrypt, libgpg-error fixes the following issues:
Update libgcrypt to 1.12.1 (jsc#PED-15059):
* New and extended interfaces:
- Allow access to the FIPS service indicator via the new
GCRYCTL_FIPS_SERVICE_INDICATOR control code.
- Make SHA-1 non-FIPS internally for the 1.12 API
- Add Dilithium (ML-DSA) support
- Support optional random-override and support byte string data
* Bug fixes:
- Use secure MPI in _gcry_mpi_assign_limb_space.
- Use CSIDL_COMMON_APPDATA instead of /etc on Windows.
- Apply a Kyber patch from upstream.
- Fix an edge case in Jent initialization.
- mceliece6688128f: Fix stack overflow crash on win64/wine
* Performance:
- Many performance improvements, new AVX512 implementations for modern CPUs.
- Add RISC-V Zbb+Zbc implementation of CRC.
- Add RISC-V vector cryptography implementation of GHASH, AES, SHA256 and SHA512
- Add AVX2 and AVX512 code paths to improve CRC.
For a full changelog, see:
https://dev.gnupg.org/source/libgcrypt/history/master/;libgcrypt-1.12.0
Update libgpg-error to 1.58:
* New src/gpg-error.c (main): New command "fconcat".
* Rename src/spawn-posix.c (struct gpgrt_spawn_actions): Rename the field to
ENVP.
* argparse: Use SYSCONFDIR for /etc.
* Update translations for Portugese, German
* src/estream.c (parse_mode): Fix parsing of "share". Set sysopen
flag.
* syscfg: Add 64-bit Android arch.
