== Changes ==
* allowedips: initialize list head when removing intermediate nodes
Fix for an important regression in removing allowed IPs from the last
snapshot. We have new test cases to catch these in the future as well.
* wg-quick: freebsd: rebreak interface loopback, while fixing localhost
* wg-quick: freebsd: export TMPDIR when restoring and don't make empty
Two fixes for FreeBSD which have already been backported into ports.
* tools: genkey: account for short reads of /dev/urandom
* tools: add support for Haiku
The tools now support Haiku! Maybe somebody is working on a WireGuard
implementation for it?
* tools: warn if an AllowedIP has a nonzero host part
If you try to run `wg set wg0 peer ... allowed-ips 192.168.1.82/24`, wg(8)
will now print a warning. Even though we mask this automatically down to
192.168.1.0/24, usually when people specify it like this, it's a mistake.
* wg-quick: add 'strip' subcommand
The new strip subcommand prints the config file to stdout after stripping
it of all wg-quick-specific options. This enables tricks such as:
`wg addconf $DEV <(wg-quick strip $DEV)`.
* tools: avoid unneccessary next_peer assignments in sort_peers()
Small C optimization the compiler was probably already doing.
* peerlookup: rename from hashtables
* allowedips: do not use __always_inline
* device: use skb accessor functions where possible
Suggested tweaks from Dave Miller.
* qemu: set framewarn 1280 for 64bit and 1024 for 32bit
These should indicate to us more clearly when we cross the most strict stack
thresholds expected when using recent compilers with the kernel.
* blake2s: simplify
* blake2s: remove outlen parameter from final
The blake2s implementation has been simplified, since we don't use any of the
fancy tree hashing parameters or the like. We also no longer separate the
output length at initialization time from the output length at finalization
time.
* global: the _bh variety of rcu helpers have been unified
* compat: nf_nat_core.h was removed upstream
* compat: backport skb_mark_not_on_list
The usual assortment of compat fixes for Linux 5.1.

The build of the perf utility has been quite bothersome,
with different arches and kernel versions failing.
Since we now have the ful kernel source in the package,
factor out the actual build into Dockerfile.perf

* wg-quick: freebsd: allow loopback to work
FreeBSD adds a route for point-to-point destination addresses. We don't
really want to specify any destination address, but unfortunately we
have to. Before we tried to cheat by giving our own address as the
destination, but this had the unfortunate effect of preventing
loopback from working on our local ip address. We work around this with
yet another kludge: we set the destination address to 127.0.0.1. Since
127.0.0.1 is already assigned to an interface, this has the same effect
of not specifying a destination address, and therefore we accomplish the
intended behavior. Note that the bad behavior is still present in Darwin,
where such workaround does not exist.
* tools: remove unused check phony declaration
* highlighter: when subtracting char, cast to unsigned
* chacha20: name enums
* tools: fight compiler slightly harder
* tools: c_acc doesn't need to be initialized
* queueing: more reasonable allocator function convention
Usual nits.
* systemd: wg-quick should depend on nss-lookup.target
Since wg-quick(8) calls wg(8) which does hostname lookups, we should
probably only run this after we're allowed to look up hostnames.
* compat: backport ALIGN_DOWN
* noise: whiten the nanoseconds portion of the timestamp
This mitigates unrelated sidechannel attacks that think they can turn
WireGuard into a useful time oracle.
* hashtables: decouple hashtable allocations from the main device allocation
The hashtable allocations are quite large, and cause the device allocation in
the net framework to stall sometimes while it tries to find a contiguous
region that can fit the device struct. To fix the allocation stalls, decouple
the hashtable allocations from the device allocation and allocate the
hashtables with kvmalloc's implicit __GFP_NORETRY so that the allocations fall
back to vmalloc with little resistance.
* chacha20poly1305: permit unaligned strides on certain platforms
The map allocations required to fix this are mostly slower than unaligned
paths.
* noise: store clamped key instead of raw key
This causes `wg show` to now show the right thing. Useful for doing
comparisons.
* compat: ipv6_stub is sometimes null
On ancient kernels, ipv6_stub is sometimes null in cases where IPv6 has
been disabled with a command line flag or other failures.
* Makefile: don't duplicate code in install and modules-install
* Makefile: make the depmod path configurable
* queueing: net-next has changed signature of skb_probe_transport_header
A 5.1 change. This could change again, but for now it allows us to keep this
snapshot aligned with our upstream submissions.
* netlink: don't remove allowed ips for new peers
* peer: only synchronize_rcu_bh and traverse trie once when removing all peers
* allowedips: maintain per-peer list of allowedips
This is a rather big and important change that makes it much much faster to do
operations involving thousands of peers. Batch peer/allowedip addition and
clearing is several orders of magnitude faster now.

* 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.
* noise: replace getnstimeofday64 with ktime_get_real_ts64
* ratelimiter: totalram_pages is now a function
* qemu: enable FP on MIPS
Linux 5.0 support.
* 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
constant time than emscripten's 64-bit integers.
* contrib: introduce simple highlighter library
This is the highlighter library being used in:
- https://twitter.com/EdgeSecurity/status/1085294681003454465
- https://twitter.com/EdgeSecurity/status/1081953278248796165
It's included here as a contrib example, so that others can paste it into
their own GUI clients for having the same strictly validating highlighting.
* netlink: use __kernel_timespec for handshake time
This readies us for Y2038. See https://lwn.net/Articles/776435/ for more info.

After 'make oldconfig' we check that that the kernel config
is as we expect and error if they don't. We used to print
the default 'diff' output on a mismatch but a unified diff
is easier to read.

While we can re-create the kernel source code we don't have it
handily available in one place. This commit stashes the kernel
and the WireGuard source as /src/linux.tar.xz and
/src/wireguard.tar.xz in the kernel package.
This increases the size of the hub image by around 100MB.

This microcode bundle comes with a file called "list"
which seems to confuse the 'iucode_tool', so we just
remove it.
