NEWS for the Nettle 3.9 release
This release includes bug fixes, several new features, a few
performance improvements, and one performance regression
affecting GCM on certain platforms.
The new version is intended to be fully source and binary
compatible with Nettle-3.6. The shared library names are
libnettle.so.8.7 and libhogweed.so.6.7, with sonames
libnettle.so.8 and libhogweed.so.6.
This release includes a rewrite of the C implementation of
GHASH (dating from 2011), as well as the plain x86_64 assembly
version, to use precomputed tables in a different way, with
tables always accessed in the same sequential manner.
This should make Nettle's GHASH implementation side-channel
silent on all platforms, but considerably slower on platforms
without carry-less mul instructions. E.g., benchmarks of the C
implementation on x86_64 showed a slowdown of 3 times.
Bug fixes:
* Fix bug in ecdsa and gostdsa signature verify operation, for
the unlikely corner case that point addition really is point
duplication.
* Fix for chacha on Power7, nettle's assembly used an
instruction only available on later processors. Fixed by
Mamone Tarsha.
* GHASH implementation should now be side-channel silent on
all architectures.
* A few portability fixes for *BSD.
New features:
* Support for the SM4 block cipher, contributed by Tianjia
Zhang.
* Support for the Balloon password hash, contributed by Zoltan
Fridrich.
* Support for SIV-GCM authenticated encryption mode,
contributed by Daiki Ueno.
* Support for OCB authenticated encryption mode.
* New exported functions md5_compress, sha1_compress,
sha256_compress, sha512_compress, based on patches from
Corentin Labbe.
Optimizations:
* Improved sha256 performance, in particular for x86_64 and
s390x.
* Use GMP's mpn_sec_tabselect, which is implemented in
assembly on many platforms, and delete the similar nettle
function. Gives a modest speedup to all ecc operations.
* Faster poly1305 for x86_64 and ppc64. New ppc code
contributed by Mamone Tarsha.
Miscellaneous:
* New ASM_FLAGS variable recognized by configure.
* Delete all arcfour assembly code. Affects 32-bit x86, 32-bit
and 64-bit sparc.
Known issues:
* Version 6.2.1 of GNU GMP (the most recent GMP release as of
this writing) has a known issue for MacOS on 64-bit ARM: GMP
assembly files use the reserved x18 register. On this
platform it is recommended to use a GMP snapshot where this
bug is fixed, and upgrade to a later GMP release when one
becomes available.
* Also on MacOS, Nettle's testsuite may still break due to
DYLD_LIBRARY_PATH being discarded under some circumstances.
As a workaround, use
* make check EMULATOR='env DYLD_LIBRARY_PATH=$(TEST_SHLIB_DIR)'

3.8.1 release
This is a bugfix release, fixing a few portability issues
reported for Nettle-3.8.
Bug fixes:
* Avoid non-posix m4 argument references in the chacha
implementation for arm64, powerpc64 and s390x. Reported by
Christian Weisgerber, fix contributed by Mamone Tarsha.
* Use explicit .machine pseudo-ops where needed in s390x
assembly files. Bug report by Andreas K. Huettel, fix
contributed by Mamone Tarsha.
Optimizations:
* Implemented runtime detection of cpu features for OpenBSD on
arm64. Contributed by Christian Weisgerber.
The new version is intended to be fully source and binary
compatible with Nettle-3.6. The shared library names are
libnettle.so.8.6 and libhogweed.so.6.6, with sonames
libnettle.so.8 and libhogweed.so.6.
3.8 release
This release includes a couple of new features, and many
performance improvements. It adds assembly code for two more
architectures: ARM64 and S390x.
The new version is intended to be fully source and binary
compatible with Nettle-3.6. The shared library names are
libnettle.so.8.5 and libhogweed.so.6.5, with sonames
libnettle.so.8 and libhogweed.so.6.
New features:
* AES keywrap (RFC 3394), contributed by Nicolas Mora.
* SM3 hash function, contributed by Tianjia Zhang.
* New functions cbc_aes128_encrypt, cbc_aes192_encrypt,
cbc_aes256_encrypt.
On processors where AES is fast enough, e.g., x86_64 with
aesni instructions, the overhead of using Nettle's general
cbc_encrypt can be significant. The new functions can be
implemented in assembly, to do multiple blocks with reduced
per-block overhead.
Note that there's no corresponding new decrypt functions,
since the general cbc_decrypt doesn't suffer from the same
performance problem.
Bug fixes:
* Fix fat builds for x86_64 windows, these appear to never
have worked.
Optimizations:
* New ARM64 implementation of AES, GCM, Chacha, SHA1 and
SHA256, for processors supporting crypto extensions. Great
speedups, and fat builds are supported. Contributed by
Mamone Tarsha.
* New s390x implementation of AES, GCM, Chacha, memxor, SHA1,
SHA256, SHA512 and SHA3. Great speedups, and fat builds are
supported. Contributed by Mamone Tarsha.
* New PPC64 assembly for ecc modulo/redc operations,
contributed by Amitay Isaacs, Martin Schwenke and Alastair
D´Silva.
* The x86_64 AES implementation using aesni instructions has
been reorganized with one separate function per key size,
each interleaving the processing of two blocks at a time
(when the caller processes multiple blocks with each call).
This gives a modest performance improvement on some
processors.
* Rewritten and faster x86_64 poly1305 assembly.
Known issues:
* Nettle's testsuite doesn't work out-of-the-box on recent
MacOS, due to /bin/sh discarding the DYLD_LIBRARY_PATH
environment variable. Nettle's test scripts handle this in
some cases, but currently fails the test cases that are
themselves written as /bin/sh scripts. As a workaround, use
make check EMULATOR='env DYLD_LIBRARY_PATH=$(TEST_SHLIB_DIR)'
Miscellaneous:
* Updated manual to current makeinfo conventions, with no
explicit node pointers. Generate pdf version with texi2pdf,
to get working hyper links.
* Added square root functions for NIST ecc curves, as a
preparation for supporting compact point representation.
* Reworked internal GCM/ghash interfaces, simplifying assembly
implementations. Deleted unused GCM C implementation
variants with less than 8-bit lookup table.

Historically, the MD5 checksums in our LFS files serve as a protection
against broken downloads, or accidentally corrupted source files.
While the sources are nowadays downloaded via HTTPS, it make sense to
beef up integrity protection for them, since transparently intercepting
TLS is believed to be feasible for more powerful actors, and the state
of the public PKI ecosystem is clearly not helping.
Therefore, this patch switches from MD5 to BLAKE2, updating all LFS
files as well as make.sh to deal with this checksum algorithm. BLAKE2 is
notably faster (and more secure) than SHA2, so the performance penalty
introduced by this patch is negligible, if noticeable at all.
In preparation of this patch, the toolchain files currently used have
been supplied with BLAKE2 checksums as well on
https://source.ipfire.org/.

"This is a bugfix release, fixing a bug in ECDSA signature
verification that could lead to a denial of service attack
(via an assertion failure) or possibly incorrect results. It
also fixes a few related problems where scalars are required
to be canonically reduced modulo the ECC group order, but in
fact may be slightly larger.
Upgrading to the new version is strongly recommended."
