2017-12-13wg-quick: add the "Table" config optionLuis Ressel2-3/+18
* Table=auto (default) selects the current behaviour * Table=off disables creation of routes altogether * All other values are passed through to "ip route add"'s table option Signed-off-by: Luis Ressel <aranea@aixah.de>

We also reduce the optimization level, just in case, but add closure compiler into the mix. Suggested-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net>

2017-12-09global: add SPDX tags to all filesGreg Kroah-Hartman102-371/+379
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 Benjamin1-1/+3
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>

At somepoint we may need to wg_ namespace these.
2017-11-29device: clear last handshake timer on ifdownJason A. Donenfeld2-0/+2
Otherwise new handshakes might not occur immediately when the interface goes up and down. Also initialize peers to having a proper zeroed handshake jiffies.
2017-11-29compat: fix 3.10 backportJason A. Donenfeld2-0/+26
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.
2017-11-28device: do not clear keys during sleep on AndroidJason A. Donenfeld1-4/+4
This makes sense for the security model of laptops, but not for clicking phones on and off, where we actually want to be able to handle incoming packets.

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>

2017-11-22poly1305-x86_64: unclobber %rbpSamuel Neves1-131/+145
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. Donenfeld8-15/+15
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.
