Distros like Exherbo have multitarget setups with toolnames prefixed by
the arch.

I happen to like it, but package managers don't. The GNU standard [1]
says there should be a separate install-strip target. I don't like
duplicating code like that. So, instead, I'll just remove stripping all
together.

It turns out this is a somewhat natural thing to do in config files.

The C standard states:
A declaration of a parameter as ``array of type'' shall be adjusted to ``qualified pointer to
type'', where the type qualifiers (if any) are those specified within the [ and ] of the
array type derivation. If the keyword static also appears within the [ and ] of the
array type derivation, then for each call to the function, the value of the corresponding
actual argument shall provide access to the first element of an array with at least as many
elements as specified by the size expression.
By changing void func(int array[4]) to void func(int array[static 4]),
we automatically get the compiler checking argument sizes for us, which
is quite nice.

To support OS X and Windows, we have to. Ugh.

They have no permissions, so we're probably better off just creating a
socket file with the umask set, as we do in BSD.

This is designed to work with a server that follows this:
struct sockaddr_un addr = {
.sun_family = AF_UNIX,
.sun_path = "/var/run/wireguard/wguserspace0.sock"
};
int fd, ret;
ssize_t len;
socklen_t socklen;
struct wgdevice *device;
fd = socket(AF_UNIX, SOCK_DGRAM, 0);
if (fd < 0)
exit(1);
if (bind(fd, (struct sockaddr *)&addr, sizeof(addr)) < 0)
exit(1);
for (;;) {
/* First we look at how big the next message is, so we know how much to
* allocate. Note on BSD you can instead use ioctl(fd, FIONREAD, &len). */
len = recv(fd, NULL, 0, MSG_PEEK | MSG_TRUNC);
if (len < 0) {
handle_error();
continue;
}
/* Next we allocate a buffer for the received data. */
device = NULL;
if (len) {
device = malloc(len);
if (!device) {
handle_error();
continue;
}
}
/* Finally we receive the data, storing too the return address. */
socklen = sizeof(addr);
len = recvfrom(fd, device, len, 0, (struct sockaddr *)&addr, (socklen_t *)&socklen);
if (len < 0) {
handle_error();
free(device);
continue;
}
if (!len) { /* If len is zero, it's a "get" request, so we send our device back. */
device = get_current_wireguard_device(&len);
sendto(fd, device, len, 0, (struct sockaddr *)&addr, socklen);
} else { /* Otherwise, we just received a wgdevice, so we should "set" and send back the return status. */
ret = set_current_wireguard_device(device);
sendto(fd, &ret, sizeof(ret), 0, (struct sockaddr *)&addr, socklen);
free(device);
}
}

We don't want people packaging these or even using these scripts, which
are only useful for limited development circumstances, so get rid of
them. More widespread development testing techniques still exist in
src/debug.mk and src/netns.sh
