* chacha20poly1305: use slow crypto on -rt kernels on arm too
Leftover from the last commit of the previous snapshot that we forgot to
handle.
* tools: getentropy requires macOS 10.12
Small build time fixup for old versions of macOS.
* queueing: remove useless spinlocks on sc
* queueing: re-enable preemption periodically to lower latency
* simd: encapsulate fpu amortization into nice functions
* simd: no need to restore fpu state when no preemption
This will improve general system latency on preempt-enabled systems, like
desktops.
* dns-hatchet: apply resolv.conf's selinux context to new resolv.conf
Fixes wg-quick's dns hatchet on CentOS.
* qemu: bump default kernel
By bumping to 4.17.2, we actually uncovered a bug in the SLUB allocator, which
upstream is now fixing: https://lkml.org/lkml/2018/6/18/1407
* noise: take locks for ss precomputation
* netlink: maintain static_identity lock over entire private key update
Minor locking correctness fixes and optimizations.
* noise: wait for crng before taking locks
We now make sure that an outgoing packet which needs a potentially unseeded
rng won't block a call to wg(8), which takes similar locks for retrieving
data.
* receive: drop handshake packets if rng is not initialized
If the rng is unseeded, we drop incoming handshake packets, so that it's not
possible for an attacker to fill the handshake queue thereby provoking
cookies.
* ratelimiter: mitigate reference underflow
* ratelimiter: do not allow concurrent init and uninit
Minor correctness and hardening fixes, which don't fix anything particular in
WireGuard, but might be useful if our ratelimiter is ever used elsewhere.
* compat: use stabler lkml links
* poly1305: add missing string.h header
Minor fixups.
* receive: don't toggle bh
The last snapshot caused a big performance regression, which we partially
revert here. This general matter, though, will be revisited in the future,
perhaps by switching to NAPI.
* main: test poly1305 before chacha20poly1305
* poly1305: give linker the correct constant data section size
While the default bfd linker did the right thing, gold would sometimes merge
section incorrectly because of an incorrect section length field, resulting in
wrong calculations.
* simd: add missing header
Fixes a compile error on a few odd kernels.
* global: fix a few typos
* manpages: eliminate whitespace at the end of the line
* tools: fix misspelling of strchrnul in comment
Cosmetic fixups.
* global: use ktime boottime instead of jiffies
* global: use fast boottime instead of normal boottime
* compat: more robust ktime backport
We now use the equivalent of clock_gettime(CLOCK_BOOTTIME) for doing age
checks on time-limited objects, such as ephemeral keys, so that on systems
where we don't clear before sleep (like Android), we make sure to invalidate
the objects after the proper amount of time, taking into account time spent
asleep.
* wg-quick: android: prevent outgoing handshake packets from being dropped
Recent android phones block outgoing packets using iptables while the system
is asleep. This makes sense for most services, but not for a tunnel device
itself, so we work around this by inserting our own iptables rule.
* 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.

Contains a fix for a crash when forwarding packets from devices that use
flow offloading and a x86 FPU issue on -rt kernels.
Also add a post-release upstream patch fixing a compilation issue related to
memcpy().

Contains a number of important fixes. From the relase notes:
https://lists.zx2c4.com/pipermail/wireguard/2017-November/001935.html
* netlink: plug memory leak
* qemu: check for memory leaks
There was a small memory leak on the netlink configuration layer that's now
been fixed.
* netlink: make sure we reserve space for NLMSG_DONE
A rather important change - due to an upstream kernel bug, that's existed
since the advent of netlink itself, sometimes wg(8) failed to receive valid
data back from kernelspace, resulting in "ENOBUFS" when trying to dump all
peers. This patch works around it while we wait for upstream to commit the
fix.

The dependency is actually only for the kernel module (and thus on the
runtime kernel version rather than kernel headers), but as we don't know the
runtime version in kconfig and the user space part doesn't make much sense
without the kernel module this will have to do.
