Boolean attributes were parsed the same way as string attributes,
so a value of { "bool_attr": "true" } would be parsed correctly, but
{ "bool_attr": true } (without quotes) was parsed as false.

This bump fixes breakage introduced by kernel commit 8ab8786f78c3fc930f9abf6d6d85e95567de4e1f,
which is part of the 4.14.181 kernel bump, and backported ip6_dst_lookup_flow to 4.14.
This breaks the older WireGuard version currently in 19.07.
For reference, the compilation error is the one below:
build_dir/target-x86_64_musl/linux-x86_64/wireguard-linux-compat-1.0.20200506/src/compat/compat.h:104:42: error: 'const struct ipv6_stub' has no member named 'ipv6_dst_lookup'; did you mean 'ipv6_dst_lookup_flow'?

Changelogs below taken from the official release announcements.
== Changes since v1.0.20200506 ==
This release aligns with the changes I sent to DaveM for 5.7-rc7 and were
pushed to net.git about 45 minutes ago.
* qemu: use newer iproute2 for gcc-10
* qemu: add -fcommon for compiling ping with gcc-10
These enable the test suite to compile with gcc-10.
* noise: read preshared key while taking lock
Matt noticed a benign data race when porting the Linux code to OpenBSD.
* queueing: preserve flow hash across packet scrubbing
* noise: separate receive counter from send counter
WireGuard now works with fq_codel, cake, and other qdiscs that make use of
skb->hash. This should significantly improve latency spikes related to
buffer bloat. Here's a before and after graph from some data Toke measured:
https://data.zx2c4.com/removal-of-buffer-bloat-in-wireguard.png
* compat: support RHEL 8 as 8.2, drop 8.1 support
* compat: support CentOS 8 explicitly
* compat: RHEL7 backported the skb hash renamings
The usual RHEL churn.
* compat: backport renamed/missing skb hash members
The new support for fq_codel and friends meant more backporting work.
* compat: ip6_dst_lookup_flow was backported to 4.14, 4.9, and 4.4
== Changes since v1.0.20200611 ==
* qemu: always use cbuild gcc rather than system gcc
* qemu: remove -Werror in order to build ancient kernels better
* qemu: patch kernels that rely on ancient make
* qemu: force 2MB pages for binutils 2.31
* qemu: use cbuild gcc for avx512 exclusion
* qemu: add extra fill in idt handler for newer binutils
* qemu: support fetching kernels for arbitrary URLs
* qemu: patch in UTS_UBUNTU_RELEASE_ABI for Ubuntu detection
* qemu: work around broken centos8 kernel
* qemu: mark per_cpu_load_addr as static for gcc-10
Our qemu test suite can now handle more kernels and more compilers. Scroll
down to the bottom of https://www.wireguard.com/build-status/ to see the
expanded array of kernels we now test against, including some distro kernels.
* compat: widen breadth of integer constants
* compat: widen breadth of memzero_explicit backport
* compat: backport skb_scrub_packet to 3.11
* compat: widen breadth of prandom_u32_max backport
* compat: narrow the breadth of iptunnel_xmit backport
* compat: backport iptunnel_xmit to 3.11
With the expanded qemu test suite, it was possible to expand our list of
mainline kernels, so the backport compat layer is now more precise.
* compat: ubuntu appears to have backported ipv6_dst_lookup_flow
* compat: bionic-hwe-5.0/disco kernel backported skb_reset_redirect and ipv6 flow
Ubuntu kernels changed recently, so this ensures we can compile with the
latest Ubuntu releases.
* compat: remove stale suse support

(cherry picked from commit 1fd1f5e8cff18f97675ce303b05d411136b99fb0)
* compat: timeconst.h is a generated artifact
Before we were trying to check for timeconst.h by looking in the kernel
source directory. This isn't quite correct on configurations in which
the object directory is separate from the kernel source directory, for
example when using O="elsewhere" as a make option when building the
kernel. The correct fix is to use $(CURDIR), which should point to
where we want.
* compat: use bash instead of bc for HZ-->USEC calculation
This should make packaging somewhat easier, as bash is generally already
available (at least for dkms), whereas bc isn't provided by distros by
default in their build meta packages.
* socket: remove errant restriction on looping to self
It's already possible to create two different interfaces and loop
packets between them. This has always been possible with tunnels in the
kernel, and isn't specific to wireguard. Therefore, the networking stack
already needs to deal with that. At the very least, the packet winds up
exceeding the MTU and is discarded at that point. So, since this is
already something that happens, there's no need to forbid the not very
exceptional case of routing a packet back to the same interface; this
loop is no different than others, and we shouldn't special case it, but
rather rely on generic handling of loops in general. This also makes it
easier to do interesting things with wireguard such as onion routing.
At the same time, we add a selftest for this, ensuring that both onion
routing works and infinite routing loops do not crash the kernel. We
also add a test case for wireguard interfaces nesting packets and
sending traffic between each other, as well as the loop in this case
too. We make sure to send some throughput-heavy traffic for this use
case, to stress out any possible recursion issues with the locks around
workqueues.
* send: cond_resched() when processing tx ringbuffers
Users with pathological hardware reported CPU stalls on CONFIG_
PREEMPT_VOLUNTARY=y, because the ringbuffers would stay full, meaning
these workers would never terminate. That turned out not to be okay on
systems without forced preemption. This commit adds a cond_resched() to
the bottom of each loop iteration, so that these workers don't hog the
core. We don't do this on encryption/decryption because the compat
module here uses simd_relax, which already includes a call to schedule
in preempt_enable.
* selftests: initalize ipv6 members to NULL to squelch clang warning
This fixes a worthless warning from clang.
* send/receive: use explicit unlikely branch instead of implicit coalescing
Some code readibility cleanups.

(cherry picked from commit 4f6343ffe7)
As announced on the mailing list, WireGuard will be in Linux 5.6. As a
result, the wg(8) tool, used by OpenWRT in the same manner as ip(8), is
moving to its own wireguard-tools repo. Meanwhile, the out-of-tree
kernel module for kernels 3.10 - 5.5 moved to its own wireguard-linux-
compat repo. Yesterday, releases were cut out of these repos, so this
commit bumps packages to match. Since wg(8) and the compat kernel module
are versioned and released separately, we create a wireguard-tools
Makefile to contain the source for the new tools repo. Later, when
OpenWRT moves permanently to Linux 5.6, we'll drop the original module
package, leaving only the tools. So this commit shuffles the build
definition around a bit but is basically the same idea as before.

(cherry picked from commit cb4d00d184)
There was an issue with the backport compat layer in yesterday's snapshot,
causing issues on certain (mostly Atom) Intel chips on kernels older than
4.2, due to the use of xgetbv without checking cpu flags for xsave support.
This manifested itself simply at module load time. Indeed it's somewhat tricky
to support 33 different kernel versions (3.10+), plus weird distro
frankenkernels.
If OpenWRT doesn't support < 4.2, you probably don't need to apply this.
But it also can't hurt, and probably best to stay updated.

Currently it seems impossible to configure /etc/config/dhcp to achieve
the following use case
- run dnsmasq with no-resolv
- re-generate /etc/resolv.conf with "nameserver 127.0.0.1"
Before this change, we have to set resolvfile to /tmp/resolv.conf.auto
to achive the 2nd effect above, but setting resolvfile requires noresolv
being false.
A new boolean option "localuse" is added to indicate that we intend to
use dnsmasq as the local dns resolver. It's false by default and to
align with old behaviour it will be true automatically if resolvfile is
set to /tmp/resolv.conf.auto

* tools: curve25519: handle unaligned loads/stores safely
This should fix sporadic crashes with `wg pubkey` on certain architectures.
* netlink: auth socket changes against namespace of socket
In WireGuard, the underlying UDP socket lives in the namespace where the
interface was created and doesn't move if the interface is moved. This
allows one to create the interface in some privileged place that has
Internet access, and then move it into a container namespace that only
has the WireGuard interface for egress. Consider the following
situation:
1. Interface created in namespace A. Socket therefore lives in namespace A.
2. Interface moved to namespace B. Socket remains in namespace A.
3. Namespace B now has access to the interface and changes the listen
port and/or fwmark of socket. Change is reflected in namespace A.
This behavior is arguably _fine_ and perhaps even expected or
acceptable. But there's also an argument to be made that B should have
A's cred to do so. So, this patch adds a simple ns_capable check.
* ratelimiter: build tests with !IPV6
Should reenable building in debug mode for systems without IPv6.

* qemu: enable FP on MIPS

* keygen-html: bring back pure javascript implementation
Benoît Viguier has proofs that values will stay well within 2^53. We
also have an improved carry function that's much simpler. Probably more

* contrib: introduce simple highlighter library

Interface triggers are installed by the dropbear init script in case an
interface is configured for a given dropbear uci section.
As dropbear is started after network the interface trigger event can be
missed during a small window; this is especially the case if lan is
specified as interface.
Fix this by starting dropbear before network so no interface trigger
is missed. As dropbear is started earlier than netifd add a boot function
to avoid the usage of network.sh functions as call to such functions will
fail at boottime.
