* wg-quick: darwin: reorder functionsJason A. Donenfeld2018-05-171-19/+19

* wg-quick: darwin: networksetup does not like missing stdioJason A. Donenfeld2018-05-171-1/+1

* wg-quick: darwin: avoid routing loop if no defaultJason A. Donenfeld2018-05-171-6/+16

* wg-quick: use invoking shell in auto rootingJason A. Donenfeld2018-05-162-2/+3
|
* wg-quick: add intentionally undocumented userspace implementation knobJason A. Donenfeld2018-05-162-3/+3
| | | | | | This knob might disappear at some point, and we don't want to encourage its use, so it's not being documented, but this should help with development of new implementations.
* wg-quick: darwin: use bash from environment and require bash 4+Jason A. Donenfeld2018-05-162-23/+23
| | | | | | For properly configured Homebrew installations /usr/local/bin should be before /bin, so this should still work. This allows the script to be used in more than one setting.

| | | | This works around a Darwin kernel bug regarding interface removal.

| | | | It's pretty rough and leaves much to be desired, but it works.

* allowedips: Fix graphviz output after endianness patchJonathan Neuschäfer2018-05-141-3/+16
| | | | | | | | | | | | 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>

* compat: don't clear header bits on RHELJason A. Donenfeld2018-05-131-1/+4
| | | | | | | | | | 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.
* compat: handle RHEL 7.5's recent backportsJason A. Donenfeld2018-05-131-5/+5

* queueing: preserve pfmemalloc header bitJason A. Donenfeld2018-05-131-0/+2

* chacha20poly1305: make gcc 8.1 happySamuel Neves2018-05-131-2/+2
| | | | | | | | | | | | | | | 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>

* poly1305: do not place constants in different sectionsJason A. Donenfeld2018-04-181-14/+1
| | | | | | | 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.

|
* send: account for route-based MTUJason A. Donenfeld2018-04-155-3/+26
| | | | | | | | | | 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>
* wg-quick: account for specified fwmark in auto routing modeJason A. Donenfeld2018-04-151-19/+23
| | | | | | | | | | | If we're doing automatic routing with default routes, but the config has also specified an explicit fwmark, then use that explicit fwmark, even if it's conflicting, since the administrator has explicitly opted into using it. Also, when shutting down the interface, we only now remove the fancy rules if we're in automatic routing mode with default routes.
