2018-05-22compat: work around qcom 4.9 backportsJason A. Donenfeld
Qualcomm backported the get_random_u32 patch, even though kernel.org didn't, which is a problem. They also backported another patch in the same place which defines a new macro variable, so use this as a differentiator. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-05-19timers: no need to clear keepalive in persistent keepaliveJason A. Donenfeld
We do this after sending the keepalive anyway. This is something of a regression, though, since before we'd cancel and then send, but now we send and then cancel, so it introduces a potential race, but hopefully that isn't too big of a deal. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-05-19timers: clear send_keepalive timer on sending handshake responseJason A. Donenfeld
We reorganize this into also doing so on sending keepalives itself, which means the state machine is much more consistent, even if this was already implied. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-05-18timers: round up instead of down in slack_timeJason A. Donenfeld
On systems with a 100hz tick, this causes handshakes to be retried in slightly less than 5 seconds, which means they aren't sent at all. This has the effect of the handshakes entirely stopping their retry cycle until the next data packet is sent. Reported-by: Andrew He <andrewhe@mit.edu> Signed-off-by: Jason A.

2018-05-14allowedips: Fix graphviz output after endianness patchJonathan Neuschäfer
Commit 5e3532e ("allowedips: use native endian on lookup") did two things: It changed the endianness of (struct allowedips_node).bits to native endian, and it moved the CIDR masking to the output code path (walk_by_peer). Adjust print_node in src/selftest/allowedips.h to deal with these changes. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-05-13compat: don't clear header bits on RHELJason A. Donenfeld
The 3.10 kernel from Red Hat puts head_frag in between headers_start and headers_end. This is triggered on the latest i40e driver. This results in the packet being freed incorrectly, crashing the system. So, this patch just ensures we don't zero any of the header bits. The whole issue of zeroing header bits probably should be revisited sometime somewhat soon. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-05-13chacha20poly1305: make gcc 8.1 happySamuel Neves
GCC 8.1 does not know about the invariant `0 <= ctx->num < POLY1305_BLOCK_SIZE`. This results in a warning that `memcpy(ctx->data + num, inp, len);` may overflow the `data` field, which is correct for arbitrary values of `num`. To make the invariant explicit we ensure that `num` is in the required range. An alternative would be to change `ctx->num` to a 4-bit bitfield at the point of declaration. This changes the code from `test ebp, ebp; jz end` to `and ebp, 15; jz end`, which have identical performance characteristics. Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Signed-off-by: Jason A.

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>
