* global: rename include'd C files to be .cJason A. Donenfeld2018-10-061-1/+1
| | | | | | | | | This is done by 259 other files in the kernel tree: linux $ rg '#include.*\.c' -l | wc -l 259 Suggested-by: Sultan Alsawaf <sultanxda@gmail.com>
* global: prefix all functions with wg_Jason A. Donenfeld2018-10-021-3/+3
| | | | | | | | | | | | | 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.

* global: put SPDX identifier on its own lineJason A. Donenfeld2018-09-201-2/+2
| | | | | The kernel has very specific rules correlating file type with comment type, and also SPDX identifiers can't be merged with other comments.
* global: always find OOM unlikelyJason A. Donenfeld2018-09-041-3/+3

* global: run through clang-formatJason A. Donenfeld2018-08-281-17/+30
| | | | | | | 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.
* ratelimiter: prevent init/uninit raceJason A. Donenfeld2018-07-311-4/+6
| | | | | | | 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>
* global: use fast boottime instead of normal boottimeJason A. Donenfeld2018-06-231-3/+3
| | | | Generally if we're inaccurate by a few nanoseconds, it doesn't matter.
* global: use ktime boottime instead of jiffiesJason A. Donenfeld2018-06-231-3/+3
| | | | | | | | 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.
* ratelimiter: do not allow concurrent init and uninitJason A. Donenfeld2018-06-191-0/+6

* global: add SPDX tags to all filesGreg Kroah-Hartman2017-12-091-1/+4
| | | | | | | | | | | | | 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. Donenfeld <Jason@zx2c4.com>
* global: style nitsJason A. Donenfeld2017-10-311-2/+4

* global: infuriating kernel iterator styleJason A. Donenfeld2017-10-311-3/+3
| | | | | | | | | | | | | | | | | 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.

|
* global: cleanup IP header checkingJason A. Donenfeld2017-06-261-2/+2
| | | | This way is more correct and ensures we're within the skb head.
* ratelimiter: rewrite from scratchJason A. Donenfeld2017-06-261-96/+153
| | | | | | | 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.

* ratelimiter: drop family from action for 4.10Jason A. Donenfeld2016-12-161-2/+0
| | | | | This was never actually used, and now that member of the struct has been removed all together from the kernel.
