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

* 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.

This version bump was made upstream mostly for OpenWRT, and should fix
an issue with a null dst when on the flow offloading path.

of this package, so trim the maintainer list a bit.

* chacha20poly1305: add mips32 implementation
"The OpenWRT Commit" - this significantly speeds up performance on cheap
plastic MIPS routers, and presumably the remaining MIPS32r2 super computers
out there.
* timers: reinitialize state on init
* timers: round up instead of down in slack_time
* timers: remove slack_time
* timers: clear send_keepalive timer on sending handshake response
* timers: no need to clear keepalive in persistent keepalive
Andrew He and I have helped simplify the timers and remove some old warts,
making the whole system a bit easier to analyze.
* tools: fix errno propagation and messages
Error messages are now more coherent.
* device: remove allowedips before individual peers
This avoids an O(n^2) traversal in favor of an O(n) one. Before systems with
many peers would grind when deleting the interface.

This makes it easier to distribute prefixes over a wireguard tunnel
interface, by simply setting the ip6prefix option in uci (just like with
other protocols).
Obviously, routing etc needs to be setup properly for things to work; this
just adds the config option so the prefix can be assigned to other
interfaces.

This is a simple version bump. Changes:
* noise: handshake constants can be read-only after init
* noise: no need to take the RCU lock if we're not dereferencing
* send: improve dead packet control flow
* receive: improve control flow
* socket: eliminate dead code
* device: our use of queues means this check is worthless
* device: no need to take lock for integer comparison
* blake2s: modernize API and have faster _final
* compat: support READ_ONCE
* compat: just make ro_after_init read_mostly
Assorted cleanups to the module, including nice things like marking our
precomputations as const.
* Makefile: even prettier output
* Makefile: do not clean before cloc
* selftest: better test index for rate limiter
* netns: disable accept_dad for all interfaces
Fixes in our testing and build infrastructure. Now works on the 4.14 rc
series.
* qemu: add build-only target
* qemu: work on ubuntu toolchain
* qemu: add more debugging options to main makefile
* qemu: simplify shutdown
* qemu: open /dev/console if we're started early
* qemu: phase out bitbanging
* qemu: always create directory before untarring
* qemu: newer packages
* qemu: put hvc directive into configuration
This is the beginning of working out a cross building test suite, so we do
several tricks to be less platform independent.
* tools: encoding: be more paranoid
* tools: retry resolution except when fatal
* tools: don't insist on having a private key
* tools: add pass example to wg-quick man page
* tools: style
* tools: newline after warning
* tools: account for padding being in zero attribute

Move wireguard from openwrt/packages to base a package.
This follows the pattern of kmod-cake and openvpn. Cake is a fast-moving
experimental kernel module that many find essential and useful. The
other is a VPN client. Both are inside of core. When you combine the two
characteristics, you get WireGuard. Generally speaking, because of the
extremely lightweight nature and "stateless" configuration of WireGuard,
many view it as a core and essential utility, initiated at boot time
and immediately configured by netifd, much like the use of things like
GRE tunnels.
WireGuard has a backwards and forwards compatible Netlink API, which
means the userspace tools should work with both newer and older kernels
as things change. There should be no versioning requirements, therefore,
between kernel bumps and userspace package bumps.
