2018-01-03receive: treat packet checking as irrelevant for timersJason A. Donenfeld
Receiving any type of authenticated data is a receive and a traversal. When it isn't a keepalive it's a data. That's our rule. Whether or not it's the correct type of data or has the right IP header shouldn't influence timer decisions. 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.

2017-12-03chacha20-arm: fix with clang -fno-integrated-as.David Benjamin
The __clang__-guarded #defines cause gas to complain if clang is passed -fno-integrated-as. Emitting .syntax unified when those are used fixes this. Reviewed-by: Andy Polyakov <appro@openssl.org> Reviewed-by: Kurt Roeckx <kurt@roeckx.be> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-11-29compat: fix 3.10 backportJason A. Donenfeld
For archs that do not provide the magic csum function, we need to provide the generic function. Also, some obscure 3.10s have backported the int size macros, so we ifndef around that to avoid potentially fatal warnings. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

This is not as ideal as using zmm, but zmm downclocks. And it's not as fast single-threaded as using the gathers. But it is faster when multithreaded, which is what WireGuard is doing. Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-11-22poly1305-x86_64: unclobber %rbpSamuel Neves
OpenSSL's Poly1305 kernels use %rbp as a scratch register. However, the kernel expects rbp to be a valid frame pointer at any given time in order to do proper unwinding. Thus we need to alter the code in order to preserve it. The most straightforward manner in which this was accomplished was by replacing $d3 in poly1305-x86_64.pl -- formerly %r10 -- by %rdi, and replace %rbp by %r10. Because %rdi, a pointer to the context structure, does not change and is not used by poly1305_iteration, it is safe to use it here, and the overhead of saving and restoring it should be minimal.

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.
