Please note that this snapshot is, like the rest of the project at this point in time, experimental, and does not consitute a real release that would be considered secure and bug-free. WireGuard is generally thought to be fairly stable, and most likely will not crash your computer (though it may). However, as this is a pre-release snapshot, it comes with no guarantees, and its security is not yet to be depended on; it is not applicable for CVEs. With all that said, if you'd like to test this snapshot out, there are a few relevant changes. == Changes == * Account for big-endian 2^26 conversion in Poly1305. * Account for big-endian NEON in Curve25519. * Fix macros in big-endian AArch64 code so that this will actually run there at all. * Prefer if (IS_ENABLED(...)) over ifdef mazes when possible. * Call simd_relax() within any preempt-disabling glue code every once in a while so as not to increase latency if folks pass in super long buffers. * Prefer compiler-defined architecture macros in assembly code, which puts us in closer alignment with upstream CRYPTOGAMS code, and is cleaner. * Non-static symbols are prefixed with wg_ to avoid polluting the global namespace. * Return a bool from simd_relax() indicating whether or not we were rescheduled. * Reflect the proper simd conditions on arm. * Do not reorder lines in Kbuild files for the simd asm-generic addition, since we don't want to cause merge conflicts. * WARN() if the selftests fail in Zinc, since if this is an initcall, it won't block module loading, so we want to be loud. * Document some interdependencies beside include statements. * Add missing static statement to fpu init functions. * Use union in chacha to access state words as a flat matrix, instead of casting a struct to a u8 and hoping all goes well. Then, by passing around that array as a struct for as long as possible, we can update counter[0] instead of state[12] in the generic blocks, which makes it clearer what's happening. * Remove __aligned(32) for chacha20_ctx since we no longer use vmovdqa on x86, and the other implementations do not require that kind of alignment either. * Submit patch to ARM tree for adjusting RiscPC's cflags to be -march=armv3 so that we can build code that uses umull. * Allow CONFIG_ARM[64] to imply [!]CONFIG_64BIT, and use zinc arch config variables consistently throughout. * Document rationale for the 2^26->2^64/32 conversion in code comments. * Convert all of remaining BUG_ON to WARN_ON. * Replace `bxeq lr` with `reteq lr` in ARM assembler to be compatible with old ISAs via the macro in . * Do not allow WireGuard to be a built-in if IPv6 is a module. * Writeback the base register and reorder multiplications in the NEON x25519 implementation. * Try all combinations of different implementations in selftests, so that potential bugs are more immediately unearthed. * Self tests and SIMD glue code work with #include, which lets the compiler optimize these. Previously these files were .h, because they were included, but a simple grep of the kernel tree shows 259 other files that carry out this same pattern. Only they prefer to instead name the files with a .c instead of a .h, so we now follow the convention. * Support many more platforms in QEMU, especially big endian ones. * Kernels < 3.17 don't have read_cpuid_part, so fix building there.
