* curve25519: arm: do not modify sp directly * compat: support neon.h on old kernels * compat: arch-namespace certain includes * compat: move simd.h from crypto to compat since it's going upstream This fixes a decent amount of compat breakage and thumb2-mode breakage introduced by our move to Zinc. * crypto: use CRYPTOGAMS license Rather than using code from OpenSSL, use code directly from AndyP. * poly1305: rewrite self tests from scratch * poly1305: switch to donna This makes our C Poly1305 implementation a bit more intensely tested and also faster, especially on 64-bit systems. It also sets the stage for moving to a HACL* implementation when that's ready. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* Kconfig: use new-style help marker * global: run through clang-format * uapi: reformat * global: satisfy check_patch.pl errors * global: prefer sizeof(*pointer) when possible * global: always find OOM unlikely Tons of style cleanups. * crypto: use unaligned helpers We now avoid unaligned accesses for generic users of the crypto API. * crypto: import zinc More style cleanups and a rearrangement of the crypto routines to fit how this is going to work upstream. This required some fairly big changes to our build system, so there may be some build errors we'll have to address in subsequent snapshots. * compat: rng_is_initialized made it into 4.19 We therefore don't need it in the compat layer anymore. * curve25519-hacl64: use formally verified C for comparisons The previous code had been proved in Z3, but this new code from upstream KreMLin is directly generated from the F*, which is preferable. The assembly generated is identical. * curve25519-x86_64: let the compiler decide when/how to load constants Small performance boost. * curve25519-arm: reformat * curve25519-arm: cleanups from lkml * curve25519-arm: add spaces after commas * curve25519-arm: use ordinary prolog and epilogue * curve25519-arm: do not waste 32 bytes of stack * curve25519-arm: prefix immediates with # This incorporates ASM nits from upstream review.

* send: switch handshake stamp to an atomic Rather than abusing the handshake lock, we're much better off just using a boring atomic64 for this. It's simpler and performs better. Also, while we're at it, we set the handshake stamp both before and after the calculations, in case the calculations block for a really long time waiting for the RNG to initialize. * compat: better atomic acquire/release backport This should fix compilation and correctness on several platforms. * crypto: move simd context to specific type This was a suggestion from Andy Lutomirski on LKML. * chacha20poly1305: selftest: use arrays for test vectors We no longer have lines so long that they're rejected by SMTP servers. * qemu: add easy git harness This makes it a bit easier to use our qemu harness for testing our mainline integration tree. * curve25519-x86_64: avoid use of r12 This causes problems with RAP and KERNEXEC for PaX, as r12 is a reserved register. * chacha20: use memmove in case buffers overlap A small correctness fix that we never actually hit in WireGuard but is important especially for moving this into a general purpose library. * curve25519-hacl64: simplify u64_eq_mask * curve25519-hacl64: correct u64_gte_mask Two bitmath fixes from Samuel, which come complete with a z3 script proving their correctness. * timers: include header in right file This fixes compilation in some environments. * netlink: don't start over iteration on multipart non-first allowedips Matt Layher found a bug where a netlink dump of peers would never terminate in some circumstances, causing wg(8) to keep trying forever. We now have a fix as well as a unit test to mitigate this, and we'll be looking to create a fuzzer out of Matt's nice library. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

This watchdog script tries to re-resolve hostnames for inactive WireGuard peers. Use it for peers with a frequently changing dynamic IP. persistent_keepalive must be set, recommended value is 25 seconds. Run this script from cron every minute: echo '* * * * * /usr/bin/wireguard_watchdog' >> /etc/crontabs/root Signed-off-by: Aleksandr V.

* device: print daddr not saddr in missing peer error * receive: style Debug messages now make sense again. * wg-quick: android: support excluding applications Android now supports excluding certain apps (uids) from the tunnel. * selftest: ratelimiter: improve chance of success via retry * qemu: bump default kernel version * qemu: decide debug kernel based on KERNEL_VERSION Some improvements to our testing infrastructure. * receive: use NAPI on the receive path This is a big change that should both improve preemption latency (by not disabling it unconditionally) and vastly improve rx performance on most systems by using NAPI. The main purpose of this snapshot is to test out this technique. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

This version bump was made upstream mostly for OpenWRT, and should fix an issue with a null dst when on the flow offloading path. While we're at it, Kevin and I are the only people actually taking care of this package, so trim the maintainer list a bit. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
