2018-04-18poly1305: do not place constants in different sectionsJason A. Donenfeld
We're referencing these constants as one contiguous blob, so if there's any merging that goes on with other constants elsewhere (such as the kernel's current poly1305 implementation that we hope to replace), then these will be reordered and have the wrong values.

2018-04-15send: account for route-based MTUJason A. Donenfeld
It might be that a particular route has a different MTU than the interface, via `ip route add ... dev wg0 mtu 1281`, for example. In this case, it's important that we don't accidently pad beyond the end of the MTU. We accomplish that in this patch by carrying forward the MTU from the dst if it exists. We also add a unit test for this issue. Reported-by: Roman Mamedov <rm.wg@romanrm.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-02-20queueing: skb_reset: mark as xnetJason A. Donenfeld
This was avoided for a long time, because I wanted the packet to be charged to the original socket for as long as possible. However, this broke net_cls, which looks at skb->sk for additional late-stage routing decisions. So we had no choice but to ensure that skb->sk is NULL by the time of xmit, and this means calling the skb destructor. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-02-14allowedips: indicate to clang-analyzer that trie is non-nullJason A. Donenfeld
We check it in the block just above the only call to node_placement, so we're certain this is the case. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-02-12socket: free skb if there isn't an endpointJason A. Donenfeld
Because the packet transmission interface in Linux, in general, has the characteristic of "consuming" skbs, our own socket_send family too must always consume skbs. This means that when a caller passes an skb to a socket_send function, he looses ownership and expects for the skb to be freed by the socket_send function, not by himself. Therefore, it's important that we actually carry out this contract under all circumstances, even when there's no endpoint available. This condition could be hit by setting up a peer with a persistent keepalive but no endpoint, or by removing an endpoint once packets were queued up to be sent already. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-01-23qemu: disable AVX-512 in userlandJason A. Donenfeld
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
