This is a bugfix release.
Bug fixes:
* Fixed a bug in the new ECC code. The ecc_j_to_a function
called GMP:s mpn_mul_n (via ecc_modp_mul) with overlapping
input and output arguments, which is not supported.
* The assembly files for SHA1, SHA256 and AES depend on ARMv6
instructions, breaking nettle-2.7 for pre-v6 ARM processors.
The configure script now enables those assembly files only
when building for ARMv6 or later.
* Use a more portable C expression for rotations. The
previous version used the following "standard" expression
for 32-bit rotation:
(x << n) | (x >> (32 - n))
But this gives undefined behavior (according to the C
specification) for n = 0. The rotate expression is replaced
by the more portable:
(x << n) | (x >> ((-n)&31))
This change affects only CAST128, which uses non-constant
rotation counts. Unfortunately, the new expression is poorly
optimized by released versions of gcc, making CAST128 a bit
slower. This is being fixed by the gcc hackers, see
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57157.
The following problems have been reported, but are *not* fixed
in this release:
* ARM assembly files use instruction syntax which is not
supported by all assemblers. Workaround: Use a current
version of GNU as, or configure with --disable-assembler.
* Configuring with --disable-static doesn't work on windows.
The libraries are intended to be binary compatible with
nettle-2.2 and later. The shared library names are
libnettle.so.4.7 and libhogweed.so.2.5, with sonames still
libnettle.so.4 and libhogweed.so.2.
