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>
2018-08-03peer: ensure destruction doesn't raceJason A. Donenfeld
Completely rework peer removal to ensure peers don't jump between contexts and create races. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-07-31noise: remove outdated commentJason A. Donenfeld
docs/protocol.md hasn't existed for 3 years. 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.

2017-10-02noise: use spinlock for rotating keysJason A. Donenfeld
This should only really be contended in extremely exceptional cases, so changing from a mutex to a spinlock is likely fine. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-08-02c: specify static array size in function paramsJason A. Donenfeld
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2016-06-25nonce: switch to RFC6479 to better support packet reorderingJason A. Donenfeld
With packets hitting multiple cores, a 64bit backtrack was too small. This algorithm increases our backtrack to 1984bits. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
