Jason A. Donenfeld cef7ac9ef9 global: put SPDX identifier on its own line
The kernel has very specific rules correlating file type with comment
type, and also SPDX identifiers can't be merged with other comments.

Greg Kroah-Hartman 01d00bc035 global: add SPDX tags to all files
It's good to have SPDX identifiers in all files as the Linux kernel
developers are working to add these identifiers to all files.

Update all files with the correct SPDX license identifier based on the license
text of the project or based on the license in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of the
full boiler plate text.

Jason A. Donenfeld bc1f6be5db global: switch from timeval to timespec
This gets us nanoseconds instead of microseconds, which is better, and
we can do this pretty much without freaking out existing userspace,
which doesn't actually make use of the nano/micro seconds field:

zx2c4@thinkpad ~ $ cat a.c
void main()
{
        puts(sizeof(struct timeval) == sizeof(struct timespec) ? "success" : "failure");
}
zx2c4@thinkpad ~ $ gcc a.c -m64 && ./a.out
success
zx2c4@thinkpad ~ $ gcc a.c -m32 && ./a.out
success

This doesn't solve y2038 problem, but timespec64 isn't yet a thing in
userspace.

Jason A. Donenfeld d9d0a2cbed global: infuriating kernel iterator style
One types:

   for (i = 0 ...

So one should also type:

  for_each_obj (obj ...

But the upstream kernel style guidelines are insane, and so we must
instead do:

  for_each_obj(obj ...

Ugly, but one must choose his battles wisely.

Jason A. Donenfeld e13b1e719b wg: warn once on unrecognized items
DaveM suggests we do in fact do this. Others on the same thread weren't
happy about the length of the proposed message, so we also give a bit of
a less dramatic warning.

This reverts commit a2cc976a3b572cf308cc2d97c080eacac60416fe.

Jason A. Donenfeld 9ef84af8c0 wg: use key_is_zero for comparing to zeros
Maybe an attacker on the system could use the infoleak in /proc to gauge
how long a wg(8) process takes to complete and determine the number of
leading zeros. This is somewhat ridiculous, but it's possible somebody
somewhere might at somepoint care in the future, so alright.
