2018-10-02global: prefix all functions with wg_Jason A. Donenfeld
I understand why this must be done, though I'm not so happy about having to do it. In some places, it puts us over 80 chars and we have to break lines up in further ugly ways. And in general, I think this makes things harder to read. Yet another thing we must do to please upstream. Maybe this can be replaced in the future by some kind of automatic module namespacing logic in the linker, or even combined with LTO and aggressive symbol stripping.

2018-09-20global: put SPDX identifier on its own lineJason A. Donenfeld
The kernel has very specific rules correlating file type with comment type, and also SPDX identifiers can't be merged with other comments. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-08-28global: run through clang-formatJason A. Donenfeld
This is the worst commit in the whole repo, making the code much less readable, but so it goes with upstream maintainers. We are now woefully wrapped at 80 columns. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-07-31ratelimiter: prevent init/uninit raceJason A. Donenfeld
Fixes a classic ABA problem that isn't actually reachable because of rtnl_lock, but it's good to be correct anyway. Reported-by: Jann Horn <jann@thejh.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-06-23global: use fast boottime instead of normal boottimeJason A. Donenfeld
Generally if we're inaccurate by a few nanoseconds, it doesn't matter. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-06-23global: use ktime boottime instead of jiffiesJason A. Donenfeld
Since this is a network protocol, expirations need to be accounted for, even across system suspend. On real systems, this isn't a problem, since we're clearing all keys before suspend. But on Android, where we don't do that, this is something of a problem. So, we switch to using boottime instead of jiffies. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-12-09global: add SPDX tags to all filesGreg Kroah-Hartman
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. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Modified-by: Jason A.

2017-10-31global: infuriating kernel iterator styleJason A. Donenfeld
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-06-26ratelimiter: rewrite from scratchJason A. Donenfeld
This not only removes the depenency on x_tables, but it also gives us much better performance and memory usage. Now, systems are able to have millions of WireGuard interfaces, without having to worry about a thundering herd of garbage collection. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
