* Revert "wg-quick: wait on process substitutions"Jason A. Donenfeld2020-08-271-14/+14
| | | | | | | | | | | | | | | | | | This reverts commit 26683f6c9ad18d9914b23312c221f27fd5ecab51, which means the old problem comes back. That's an issue. But waiting on process substitutions is not available with commonly used bash versions: # wg-quick up demo [#] ip link add demo type wireguard [#] wg setconf demo /dev/fd/63 /usr/bin/wg-quick: line 251: wait: pid 2955 is not a child of this shell [#] ip link delete dev demo This means we have to wait a few years before fixing this issue. IOW, bash limitation; can't fix. Reported-by: Theodore Mozzo <theodore.mozzo@gmail.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* wg-quick: wait on process substitutionsJason A. Donenfeld2020-08-061-14/+14
| | | | | | | | | Bash does not propagate error values, which is a bummer, but process substitutions are a useful feature. Introduce a new idiom to deal with this: either "; wait $!" after the line to propagate the error, or "|| true" to indicate explicitly that we don't care about the error. Signed-off-by: Jason A.

* wg-quick: support dns search domainsJason A. Donenfeld2020-05-091-5/+25
| | | | | | | If DNS= has an IP in it, treat it as a DNS server. If DNS= has a non-IP in it, treat it as a DNS search domain. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* wg-quick: darwin: support being called from launchdJason A. Donenfeld2019-06-241-1/+16
| | | | | | | | 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> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* wg-quick: add 'strip' subcommandLuis Ressel2019-03-231-1/+9
| | | | | | | | | | `wg-quick strip` prints the config file to stdout after stripping it of all wg-quick-specific options. This enables tricks such as `wg addconf $DEV <(wg-quick strip $DEV)`. Signed-off-by: Luis Ressel <aranea@aixah.de> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* wg-quick: darwin: prefer system paths for toolsJason A. Donenfeld2018-08-121-1/+1
| | | | | | | | | | | | | The only things wg-quick(8) needs from Homebrew are bash(1) and wg(8). Other than that, it's explicitly coded against the native system utilities. Since wg-quick(8) and bash(1) are invoked in auto_su by their full absolute path (via $SELF and $BASH, respectively), we can simply set the $PATH to be prefixed by the default system binary paths. This way, if users install tools that conflict with system tools -- such as GNU coreutils -- we won't accidently call those.

* wg-quick: allow link local default gatewayJason A. Donenfeld2018-07-161-1/+0
| | | | | | | | It's unclear why it was like this in the first place, but it apparently broke certain IPv6 setups. Reported-by: Jonas Blahut <j@die-blahuts.de> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* wg-quick: darwin: set DNS servers after delay on route changeJason A. Donenfeld2018-05-311-2/+6
| | | | | | | | This works around a race condition in macOS's network daemons, while also adding one in the form of possibly calling kill -ALRM on a stale PID; unfortunately bash can't wait from a trap. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

| | | | | | | | This knob might disappear at some point, and we don't want to encourage its use, so it's not being documented, but this should help with development of new implementations. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

| | | | | | | | For properly configured Homebrew installations /usr/local/bin should be before /bin, so this should still work. This allows the script to be used in more than one setting. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
