* wg-quick: android: do not choke on empty allowed-ipsJason A. Donenfeld2018-11-111-1/+4
| | | | Reported-by: Samuel Holland <samuel@sholland.org>
* wg.8: AllowedIPs isn't actually requiredJason A. Donenfeld2018-10-191-1/+1
| | | | | | | An empty allowed IPs is totally valid, for folks wishing to move IP addresses between multiple peers atomically. Suggested-by: Comex <comexk@gmail.com>
* wg.8: specify that wg(8) shows runtime info tooJason A. Donenfeld2018-10-191-1/+1
| | | | Suggested-by: Comex <comexk@gmail.com>
* tools: wg-quick: wait for interface to disappear on freebsdJason A. Donenfeld2018-10-131-0/+9

* tools: don't fail if a netlink interface dump is inconsistentJason A. Donenfeld2018-10-131-2/+9
| | | | | | | | | | Netlink returns NLM_F_DUMP_INTR if the set of all tunnels changed during the dump. That's unfortunate, but is pretty common on busy systems that are adding and removing tunnels all the time. Rather than retrying, potentially indefinitely, we just work with the partial results. Reported-by: Robert Gerus <ar@is-a.cat>
* tools: compile on gnu99Jason A. Donenfeld2018-10-091-1/+1
| | | | | | | We don't actually use any C11 features, so we can at least compile with ancient gcc. Reported-by: Aaron M. D. Jones <aaronmdjones@gmail.com>
* tools: use libc's endianness macro if no compiler macroJason A. Donenfeld2018-10-091-0/+10
| | | | | | This lets us be compiled with ancient gcc. Reported-by: Jeff Brandt <jeff@jeffcolo.net>
* netlink: do not stuff index into nla typeJason A. Donenfeld2018-10-081-5/+4
| | | | | | | It's not used for anything, and LKML doesn't like the type being used as an index value. Suggested-by: Eugene Syromiatnikov <esyr@redhat.com>
* crypto: clean up remaining .h->.cJason A. Donenfeld2018-10-071-2/+2
|
* wg-quick.8: add policy routing exampleJason A. Donenfeld2018-10-051-0/+26
| | | | | Suggested-by: Toke Høiland-Jørgensen <toke@toke.dk> Suggested-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
* crypto: make constant naming scheme consistentJason A. Donenfeld2018-09-252-7/+7
|
* global: put SPDX identifier on its own lineJason A. Donenfeld2018-09-2022-44/+44
| | | | | The kernel has very specific rules correlating file type with comment type, and also SPDX identifiers can't be merged with other comments.
* global: prefer sizeof(*pointer) when possibleJason A. Donenfeld2018-09-043-13/+13
| | | | Suggested-by: Sultan Alsawaf <sultanxda@gmail.com>
* crypto: import zincJason A. Donenfeld2018-09-031-2/+2
|
* tools: ipc: do not warn on unrecognized netlink attributesJason A. Donenfeld2018-09-021-17/+0
| | | | It makes extending things more difficult.
* crypto: use unaligned helpersJason A. Donenfeld2018-08-281-0/+3
| | | | | | This is not useful for WireGuard, but for the general use case we probably want it this way, and the speed difference is mostly lost in the noise.
* wg-quick: check correct variable for route deduplicationJason A. Donenfeld2018-08-211-1/+1
| | | | Reported-by: John Sager <john@sager.me.uk>
* 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. Reported-by: Deirdre Connolly <durumcrustulum@gmail.com>
* wg-quick: android: remove compat codeJason A. Donenfeld2018-07-241-10/+0

* wg-quick: android: allow package to be overriddenJason A. Donenfeld2018-07-241-4/+9
|
* wg-quick: allow link local default gatewayJason A. Donenfeld2018-07-163-3/+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>
* tools: only error on wg show if all interfaces failJason A. Donenfeld2018-07-081-1/+4

* manpages: eliminate whitespace at the end of the lineJonathan Neuschäfer2018-06-222-26/+26
| | | | | | This eliminates a few style warnings from "mandoc -T lint src/tools/wg*.8". Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net>
* wg-quick: android: don't forget to free compiled regexesJason A. Donenfeld2018-06-171-5/+6

* wg-quick: android: disable roaming to v6 networks when v4 is specifiedJason A. Donenfeld2018-06-171-1/+54
| | | | This works around an unfortunate bug in 464XLAT transitions.
* tools: getentropy requires 10.12Jason A. Donenfeld2018-06-141-1/+7
|
* tools: support getentropy(3)Jason A. Donenfeld2018-06-081-0/+11

|
* wg-quick: android: change name of intentJason A. Donenfeld2018-06-041-1/+1
|
* wg-quick: android: delay setting users until endJason A. Donenfeld2018-05-311-1/+6
| | | | | | | `ndc users add` eventually invokes SOCK_DESTROY on user sockets, causing them to reconnect. By delaying this until after routes are set, we ensure that the sockets reconnect using the tunnel, rather than the old route.
* tools: constanter time encodingJason A. Donenfeld2018-05-311-15/+21
|
* 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.
* wg-quick: freebsd: configure as p2p linkJason A. Donenfeld2018-05-271-3/+5

* wg-quick: allow enumeration of socket filesJason A. Donenfeld2018-05-232-2/+2
| | | | | These OSes have an unpriv'd ifconfig, so this isn't an even larger info leak.

* tools: always pass -v as first argument to installJason A. Donenfeld2018-05-231-7/+7
| | | | This lets crippled OSes sed out our -v more easily.
