Without this patch, the chacha block counter is not incremented on neon rounds, resulting in incorrect calculations and corrupt packets. This also switches to using `--no-numbered --zero-commit` so that future diffs are smaller.

Subject: [PATCH] crypto: curve25519 - x86_64 library and KPP implementations
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit

|
|
commit bb611bdfd6be34d9f822c73305fcc83720499d38 upstream.
|
|
|
|
This implementation is the fastest available x86_64 implementation, and
|
|
unlike Sandy2x, it doesn't requie use of the floating point registers at
|
|
all. Instead it makes use of BMI2 and ADX, available on recent
|
|
microarchitectures. The implementation was written by Armando
|
|
Faz-Hernández with contributions (upstream) from Samuel Neves and me,
|
|
in addition to further changes in the kernel implementation from us.
