* wg-quick: linux: use already configured addresses instead of in-memoryJason A. Donenfeld2019-12-171-6/+6
| | | | | | | | | | | The ADDRESSES array might not have addresses added during PreUp. But moreover, nft(8) and iptables(8) don't like ip addresses in the form somev6prefix::someipv4suffix, such as fd00::1.2.3.4, while ip(8) can handle it. So by adding these first and then asking for them back, we always get normalized addresses suitable for nft(8) and iptables(8). Reported-by: Silvan Nagl <mail@53c70r.de> Signed-off-by: Jason A.

* wg-quick: linux: try both iptables(8) and nft(8) on teardownJason A. Donenfeld2019-12-121-1/+2
| | | | | | | | Daniel argues that technically a package manager could install nft(8) after previously having started wg-quick(8) using iptables(8). Suggested-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* wg-quick: linux: support older nft(8)Jason A. Donenfeld2019-12-121-5/+5
| | | | | | | | Older nft(8), such as that on Ubuntu, does not accept the - parameter to the -f argument and doesn't accept symbolic priority names. So instead use the canonical numeric priority forms and use <(echo) instead of -. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* wg-quick: linux: don't fail down when using systemd-resolvedRonan Pigott2019-08-271-1/+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.

| | | | | | | | | | | | The commit 7c833642 ("wg-quick: freebsd: allow loopback to work") was supposed to make things better, but actually it just started sending legitimate localhost traffic over the WireGuard interface, which is really quite bad.
