* man: document dynamic debug trick for LinuxJason A. Donenfeld2020-01-311-0/+9
| | | | | | | | This comes up occasionally, so it may be useful to mention its possibility in the man page. At least the Arch Linux and Ubuntu kernels support dynamic debugging, so this advise will at least help somebody. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* Makefile: remove pwd from compile outputJason A. Donenfeld2020-01-031-3/+3
| | | | | | | | | | We previously included $(pwd) in the compile output pretty printer, because it matched our parent out-of-tree module build. Since we're no longer coupled to the module, we can return to a prettier scheme of just using the object name. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Fixes: eb68ad07 ("Makefile: even prettier output")

| | | | | | | | | | We used to reach back into parent directories for this, but with the repo split, we now require our own copy. We use -idirafter in case system headers are installed for the wireguard.h netlink definitions. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* 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: add support for nft and prefer itJason A. Donenfeld2019-12-121-20/+39
| | | | | | | | If nft(8) is installed, use it. These rules should be identical to the iptables-restore(8) ones, with the advantage that cleanup is easy because we use custom table names. 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.
