David Anderson	7fb33123d3	wgengine/router: warn about another variation of busybox's `ip`. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	9c914dc7dd	wgengine/router: stop using -m comment. The comment module is compiled out on several embedded systems (and also gentoo, because netfilter can't go brrrr with comments holding it back). Attempting to use comments results in a confusing error, and a non-functional firewall. Additionally, make the legacy rule cleanup non-fatal, because we do have to probe for the existence of these -m comment rules, and doing so will error out on these systems.

David Anderson	3e27b3c33c	wgengine/router: more comments. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	0fe262f093	ipn: plumb NetfilterMode all the way out to the CLI. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	c67c8913c3	wgengine/router: add a test for linux router state transitions. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	292606a975	wgengine/router: support multiple levels of netfilter involvement. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Avery Pennarun	d53e8fc0da	router_darwin_support: we can build this on every platform. Our new build scripts try to build ipn-go-bridge on more than just linux and darwin, so let's enable this file so it can be successful on every platform.	5 years ago
David Anderson	9ccbcda612	wgengine/router: rename config.Settings to config.Config, make pointer. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	cd01bcc395	wgengine/router: allow loopback traffic from our own IP(s). Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	bfdc8175b1	wgengine/router: add a setting to disable SNAT for subnet routes. Part of #320. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	21ac65d3da	wgengine/router: explicitly detect and complain about busybox's `ip`. Defensive programming against #368 in environments other than Docker, e.g. if you try using Tailscale in Alpine Linux directly, sans container. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	381b94d4d1	wgengine/router: include command output if `ip rule list` fails. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	efc1feedc9	wgengine/router: include more information when iptables ops fail. The iptables package we use doesn't include command output, so we're left with guessing what went wrong most of the time. This will at least narrow things down to which operation failed. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	b01db109f5	wgengine/router: use inet.af/netaddr, not wgcfg.CIDR. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	b8f01eed34	wgengine/router: remove wireguard-go config from settings. Instead, pass in only exactly the relevant configuration pieces that the OS network stack cares about. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	8861bb5a19	wgengine/router: alter API to support multiple addrs, and use on linux. FreeBSD and OpenBSD will error out with a complaint if we pass >1 address right now, but we don't yet so that's okay.	5 years ago
David Anderson	6802481bf5	wgengine/router: don't use gateway routes on linux.	5 years ago
David Anderson	78b1ed39ea	wgengine/router: add more documentation.	5 years ago
David Anderson	c9de43cd59	wgengine/router: fix typo. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	89198b1691	wgengine/router: rewrite netfilter and routing logic. New logic installs precise filters for subnet routes, plays nice with other users of netfilter, and lays the groundwork for fixing routing loops via policy routing. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	7618d7e677	wgengine/router: simplify some cmd invocations. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	755fd9253c	wgengine/router: fix up docstring. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	1ac570def7	wgengine/router: split out from wgengine. The router implementations are logically separate, with their own API. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
