2019-08-28Makefile: allow specifying kernel releaseMikk Mar1-2/+3
This makes depmod work when building/installing the module for a kernel other than the currently running one. Signed-off-by: Mikk Mar <mikkmar@airmail.cc>
2019-08-27wg-quick: linux: don't fail down when using systemd-resolvedRonan Pigott1-1/+1
systemd-resolved has a compatibility interface for use with resolvconf scripts when resolvectl is called from a symlink from resolvconf. However, when tearing down the interface, cmd_down calls del_if and then unset_dns. In the case of systemd-resolved, deleting the interface also removes the systemd-resolved entry and causes resolvconf -d to fail when resolvconf really is a symlink to resolvectl. This causes `wg-quick down` and 'wg-quick@.service' to exit with failure. Instead we use the resolvconf '-f' flag to ignore non-existent interfaces, supported by both openresolv and sd-resolved resolvconf. Signed-off-by: Ronan Pigott <rpigott@berkeley.edu> [zx2c4: moved -f argument to end to remain compatible with Debian's resolvconf]
2019-08-25compat: account for android-4.9 backport of addr_gen_modeNathan Chancellor2-4/+4
Android kernels backported d35a00b8e33dab7385f724e713ae71c8be0a49f4, so now we need to do feature detection. Link: https://android-review.googlesource.com/c/kernel/common/+/1103831 Signed-off-by: Nathan Chancellor <natechancellor@gmail.com>
2019-08-07wg-quick: openbsd: fix alternate routing table syntaxAnkur Kothari1-1/+1
route(8) has always used the `-T` option to specify the routing table; there is no `rdomain` option. Signed-off-by: Ankur Kothari <ankur@lipidity.com>

2019-08-03compat: do not run bc on clean targetJason A. Donenfeld1-0/+2
Certain targets don't define CONFIG_*, which means this bc command was previously failing.
2019-07-19compat: support running in OpenVZ environmentsJason A. Donenfeld1-0/+8
Overriding LLTX like this is pretty ugly, but at least it means we don't have to let OpenVZ infect the real source tree. Requested-by: Benedikt Braunger <b.braunger@syseleven.de>

2019-06-25global: switch to coarse ktimeJason A. Donenfeld11-36/+43
Coarse ktime is broken until [1] in 5.2 and kernels without the backport, so we use fallback code there. The fallback code has also been improved significantly. It now only uses slower clocks on kernels < 3.17, at the expense of some accuracy we're not overly concerned about.

2019-06-24wg-quick: darwin: support being called from launchdJason A. Donenfeld3-1/+53
This causes wg-quick up to wait for the monitor to exit before it exits, so that launchd can correctly wait on it. Reported-by: Cameron Palmer <cameron@promon.no>

2019-05-29blake2s: shorten ssse3 loopSamuel Neves1-857/+66
This (mostly) preserves the performance (as measured on Haswell and *lake) of last commit, but it drastically reduces code size. Signed-off-by: Samuel Neves <sneves@dei.uc.pt>
2019-05-29blake2s,chacha: latency tweakSamuel Neves5-618/+982
In every odd-numbered round, instead of operating over the state x00 x01 x02 x03 x05 x06 x07 x04 x10 x11 x08 x09 x15 x12 x13 x14 we operate over the rotated state x03 x00 x01 x02 x04 x05 x06 x07 x09 x10 x11 x08 x14 x15 x12 x13 The advantage here is that this requires no changes to the 'x04 x05 x06 x07' row, which is in the critical path. This results in a noticeable latency improvement of roughly R cycles, for R diagonal rounds in the primitive. In the case of BLAKE2s, which I also moved from requiring AVX to only requiring SSSE3, we save approximately 30 cycles per compression function call on Haswell and Skylake. In other words, this is an improvement of ~0.6 cpb. This idea was pointed out to me by Shunsuke Shimizu, though it appears to have been around for longer.
