2020-02-05netlink: don't pretend that sysconf isn't a functionJason A. Donenfeld2-4/+15
We can cache the value of this instead of evaluating every time. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-02-03netlink: remove libmnl requirementJason A. Donenfeld9-375/+792
It turns out that the binary actually gets smaller if we simply inline the very small parts of libmnl that we need. Since we wind up needing the mnlg bits anyway, there's little benefit in linking to libmnl. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2020-02-01extract-{handshakes,keys}: rework for upstream kernelJason A. Donenfeld4-16/+6
Now that WireGuard has been upstreamed and the repos split, we have to look elsewhere for these headers. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-01-31man: document dynamic debug trick for LinuxJason A. Donenfeld1-0/+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>

2020-01-03Makefile: remove pwd from compile outputJason A. Donenfeld1-3/+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")

2019-12-26wg: add back source formerly shared with kernel moduleJason A. Donenfeld7-5/+1845
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>

2019-12-17wg-quick: linux: use already configured addresses instead of in-memoryJason A. Donenfeld1-6/+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. Donenfeld <Jason@zx2c4.com>

2019-12-12wg-quick: linux: try both iptables(8) and nft(8) on teardownJason A. Donenfeld1-1/+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>
2019-12-12wg-quick: linux: support older nft(8)Jason A. Donenfeld1-5/+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>

2019-12-12wg-quick: linux: add support for nft and prefer itJason A. Donenfeld1-20/+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>
