Routine version bump that also removes the necessity of carrying that extra patch. Changes: * Kconfig: remove trailing whitespace * allowedips: rename from routingtable * tools: remove ioctl cruft * global: revert checkpatch.pl changes Cleanliness. * device: please lockdep * device: wait for all peers to be freed before destroying These make the various checkers happy. * netlink: plug memory leak * qemu: check for memory leaks There was a small memory leak on the netlink configuration layer that's now been fixed. * receive: hoist fpu outside of receive loop Should be a small speedup on x86_64. * qemu: more debugging * qemu: bump kernel version Significantly more debugging checkers have been turned on. * wg-quick: stat the correct enclosing folder of config file * wg-quick: allow for tabs in keys Minor fixups for wg-quick(8). * compat: 4.4.0 has strange ECN function Nobody actually runs base 4.4.0, but this is more correct anyway. * netlink: make sure we reserve space for NLMSG_DONE A rather important change - due to an upstream kernel bug, that's existed since the advent of netlink itself, sometimes wg(8) failed to receive valid data back from kernelspace, resulting in "ENOBUFS" when trying to dump all peers. This patch works around it while we wait for upstream to commit the fix. * curve25519: reject deriving from NULL private keys * tools: allow for NULL keys everywhere A null 25519 private point isn't a valid point (prior to normalization), which is why we use it as the "unsetting" value. Conversely, however, except for psk, we should be using the existence of it in the netlink message being an indication of whether or not it's set, for the tools. Signed-off-by: Jason A.

See ../docs/kernel-patches.md for more information on kernel builds.
To build with various debug options enabled, build the kernel with
make DEBUG=1. The options enabled are listed in kernel_config.debug.
This allocates a significant amount of memory on boot and you may need to
adjust the kernel config on some systems. Specifically:
