> Hello,
>
> A new snapshot, `0.0.20190702`, has been tagged in the git repository.
>
> Please note that this snapshot is, like the rest of the project at this point
> in time, experimental, and does not constitute 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 ==
>
> * curve25519: not all linkers support bmi2 and adx
>
> This should allow WireGuard to build on older toolchains.
>
> * qemu: show signal when failing
>
> This was useful in tracking down upstream armeb bugs such as:
> http://lists.infradead.org/pipermail/linux-arm-kernel/2019-May/655926.html
>
> * wg-quick: darwin: support being called from launchd
>
> We now ship a sample launchd file, for folks who would like to run WireGuard
> on macOS servers with some form of automation. Most users are still advised to
> use the GUI app from the App Store.
>
> * compat: some kernels weirdly backport prandom_u32_max
> * compat: unify custom function prefix/suffix
> * compat: rhel backported list modifications
>
> Usual maintance of our compat layer for existing platforms and kernels.
>
> * compat: support RHEL8's skb_mark_not_on_list backport
>
> We now support RHEL8/CentOS8's kernel.
>
> * global: switch to coarse ktime
>
> Our prior use of fast ktime before meant that sometimes, depending on how
> broken the motherboard was, we'd wind up calling into the HPET slow path. Here
> we move to coarse ktime which is always super speedy. In the process we had to
> fix the resolution of the clock, as well as introduce a new interface for it,
> landing in 5.3. Older kernels fall back to a fast-enough mechanism based on
> jiffies.

The new snapshot is causing build failures for my android kernel. A log
follows. I'm using the manifest drop-in described on the XDA forums [1].
The kernel source is here [2].
