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.

2017-11-22global: switch from timeval to timespecJason A. Donenfeld
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.

These changes were suggested by checkpatch.pl, but actually cause big problems depending on the options. Revert. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

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>

2017-09-18queue: entirely rework parallel systemJason A. Donenfeld
This removes our dependency on padata and moves to a different mode of multiprocessing that is more efficient. This began as Samuel Holland's GSoC project and was gradually reworked/redesigned/rebased into this present commit, which is a combination of his initial contribution and my subsequent rewriting and redesigning.

2017-06-08noise: fix race when replacing handshakeJason A. Donenfeld
Replacing an entry that's already been replaced is something that could happen when processing handshake messages in parallel, when starting up multiple instances on the same machine. Reported-by: Hubert Goisern <zweizweizwoelf@gmail.com> 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.
