* Makefile: strip prefixed v from version.h This fixes a mistake in dmesg output and when parsing the sysfs entry in the filesystem. * device: skb_list_walk_safe moved upstream This is a 5.6 change, which we won't support here, but it does make the code cleaner, so we make this change to keep things in sync. * curve25519: x86_64: replace with formally verified implementation This comes from INRIA's HACL*/Vale. It implements the same algorithm and implementation strategy as the code it replaces, only this code has been formally verified, sans the base point multiplication, which uses code similar to prior, only it uses the formally verified field arithmetic alongside reproducable ladder generation steps. This doesn't have a pure-bmi2 version, which means haswell no longer benefits, but the increased (doubled) code complexity is not worth it for a single generation of chips that's already old. Performance-wise, this is around 1% slower on older microarchitectures, and slightly faster on newer microarchitectures, mainly 10nm ones or backports of 10nm to 14nm. This implementation is "everest" below: Xeon E5-2680 v4 (Broadwell) armfazh: 133340 cycles per call everest: 133436 cycles per call Xeon Gold 5120 (Sky Lake Server) armfazh: 112636 cycles per call everest: 113906 cycles per call Core i5-6300U (Sky Lake Client) armfazh: 116810 cycles per call everest: 117916 cycles per call Core i7-7600U (Kaby Lake) armfazh: 119523 cycles per call everest: 119040 cycles per call Core i7-8750H (Coffee Lake) armfazh: 113914 cycles per call everest: 113650 cycles per call Core i9-9880H (Coffee Lake Refresh) armfazh: 112616 cycles per call everest: 114082 cycles per call Core i3-8121U (Cannon Lake) armfazh: 113202 cycles per call everest: 111382 cycles per call Core i7-8265U (Whiskey Lake) armfazh: 127307 cycles per call everest: 127697 cycles per call Core i7-8550U (Kaby Lake Refresh) armfazh: 127522 cycles per call everest: 127083 cycles per call Xeon Platinum 8275CL (Cascade Lake) armfazh: 114380 cycles per call everest: 114656 cycles per call Achieving these kind of results with formally verified code is quite remarkable, especialy considering that performance is favorable for newer chips.

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
