* tools: dedup secret normalizationJason A. Donenfeld2018-01-311-7/+1

* chacha20poly1305: better buffer alignmentJason A. Donenfeld2018-01-301-9/+8
|
* chacha20poly1305: use existing rol32 functionJason A. Donenfeld2018-01-301-9/+4
|
* tools: fread doesn't change errnoJason A. Donenfeld2018-01-301-4/+0
| | | | | Thus we might be responding to an old errno, which could cause this to unnecessarily fail.
* device: let udev know what kind of device we areJason A. Donenfeld2018-01-301-0/+6
|
* qemu: disable AVX-512 in userlandJason A. Donenfeld2018-01-231-0/+2
| | | | | | | We're trying to test kernel code, so the userland tools we use for doing that testing don't really matter to us. We turn off AVX512, because WireGuard supports kernels that do not support AVX512 userlands. It's easier to just blanket-disable it all, since it doesn't matter anyway.
* qemu: disable PIE for compilationJason A. Donenfeld2018-01-231-1/+3
| | | | | | Some old kernels never backported this fix to the build system, and it's required if we want to build those old kernels with PIE-by-default compilers.
* tools: share curve25519 implementations with kernelJason A. Donenfeld2018-01-232-1541/+32
|
* poly1305: add poly-specific self-testsJason A. Donenfeld2018-01-194-1/+1569
|
* curve25519-fiat32: uninline certain functionsJason A. Donenfeld2018-01-182-8/+8
| | | | | | | | | | | While this has a negative performance impact on x86_64, it has a positive performance impact on smaller machines, which is where we're actually using this code. For example, an A53: Before: fiat32: 228605 cycles per call After: fiat32: 188307 cycles per call

* wg-quick: ifnames have max len of 15Jason A. Donenfeld2018-01-102-3/+3
|
* socket: check for null socket before fishing out sportJason A. Donenfeld2018-01-081-2/+4
| | | | Otherwise we could have a null pointer dereference.
* global: year bumpJason A. Donenfeld2018-01-0386-87/+87
|
* receive: treat packet checking as irrelevant for timersJason A. Donenfeld2018-01-031-6/+6
| | | | | | | 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.

* crypto: compile on UMLJason A. Donenfeld2017-12-134-2/+8
| | | | We basically just don't use FPU in UML.
* wg-quick: dumber matching for default routesJason A. Donenfeld2017-12-131-1/+1

* wg-quick: add the "Table" config optionLuis Ressel2017-12-132-3/+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>

* global: add SPDX tags to all filesGreg Kroah-Hartman2017-12-0984-352/+312
| | | | | | | | | | | | | 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.

* chacha20-arm: fix with clang -fno-integrated-as.David Benjamin2017-12-031-1/+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>

* netlink: rename symbol to avoid clashesJason A. Donenfeld2017-11-293-6/+6
| | | | At somepoint we may need to wg_ namespace these.
* device: clear last handshake timer on ifdownJason A. Donenfeld2017-11-292-0/+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.
* compat: fix 3.10 backportJason A. Donenfeld2017-11-292-0/+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.
* device: do not clear keys during sleep on AndroidJason A. Donenfeld2017-11-281-4/+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.

* blake2s: tweak avx512 codeSamuel Neves2017-11-261-64/+47
| | | | | | | | 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>
