Brad Fitzpatrick	d24ed3f68e	wgengine/router: add debug knob to resort to Linux "ip" command usage Tailscale 1.18 uses netlink instead of the "ip" command to program the Linux kernel. The old way was kept primarily for tests, but this also adds a TS_DEBUG_USE_IP_COMMAND environment knob to force the old way temporarily for debugging anybody who might have problems with the new way in 1.18.

Josh Bleecher Snyder	3fd5f4380f	util/multierr: new package github.com/go-multierror/multierror served us well. But we need a few feature from it (implement Is), and it's not worth maintaining a fork of such a small module. Instead, I did a clean room implementation inspired by its API.

Brad Fitzpatrick	ff1954cfd9	wgengine/router: use netlink for ip rules on Linux Using temporary netlink fork in github.com/tailscale/netlink until we get the necessary changes upstream in either vishvananda/netlink or jsimonetti/rtnetlink.

Brad Fitzpatrick	7c40a5d440	wgengine/router: refactor in prep for Linux netlink-ification Pull out the list of policy routing rules to a data structure now shared between the add & delete paths, but to also be shared by the netlink paths in a future change.

Brad Fitzpatrick	aad46bd9ff	wgengine/router: stop cleaning up old dev rules on Linux Anybody using that one old, unreleased version of Tailscale from over a year ago should've rebooted their machine by now to get various non-Tailscale security updates. :) Change-Id: If9e043cb008b20fcd6ddfd03756b3b23a9d7aeb5 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Denton Gentry	6731f934a6	Revert "wgengine: actively log FlushDNS." This log is quite verbose, it was only to be left in for one unstable build to help debug a user issue. This reverts commit `1dd2552032`. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Denton Gentry	1dd2552032	wgengine: actively log FlushDNS. Intended to help in resolving customer issue with DNS caching. We currently exec `ipconfig /flushdns` from two places: - SetDNS(), which logs before invoking - here in router_windows, which doesn't We'd like to see a positive indication in logs that flushdns is being run. As this log is expected to be spammy, it is proposed to leave this in just long enough to do an unstable 1.13.x build and then revert it. They won't run an unsigned image that I build.

Brad Fitzpatrick	e4fecfe31d	wgengine/{monitor,router}: restore Linux ip rules when systemd deletes them Thanks. Fixes #1591 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	ed8587f90d	wgengine/router: take a link monitor Prep for #1591 which will need to make Linux's router react to changes that the link monitor observes. The router package already depended on the monitor package transitively. Now it's explicit. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Fletcher Nichol	a49df5cfda	wgenine/router: fix OpenBSD route creation The route creation for the `tun` device was augmented in #1469 but didn't account for adding IPv4 vs. IPv6 routes. There are 2 primary changes as a result: * Ensure that either `-inet` or `-inet6` was used in the [`route(8)`](https://man.openbsd.org/route) command * Use either the `localAddr4` or `localAddr6` for the gateway argument depending which destination network is being added The basis for the approach is based on the implementation from `router_userspace_bsd.go`, including the `inet()` helper function. Fixes #2048 References #1469 Signed-off-by: Fletcher Nichol <fnichol@nichol.ca>	3 years ago
Josh Bleecher Snyder	1ece91cede	go.mod: upgrade wireguard-windows, de-fork wireguard-go Pull in the latest version of wireguard-windows. Switch to upstream wireguard-go. This requires reverting all of our import paths. Unfortunately, this has to happen at the same time. The wireguard-go change is very low risk, as that commit matches our fork almost exactly. (The only changes are import paths, CI files, and a go.mod entry.) So if there are issues as a result of this commit, the first place to look is wireguard-windows changes.

Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w(.)\.Port = (.) -> $1 = $1.WithPort($2) \w(.)\.IP = (.) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

David Anderson	19eca34f47	wgengine/router: fix FreeBSD configuration failure on the v6 /48. On FreeBSD, we add the interface IP as a /48 to work around a kernel bug, so we mustn't then try to add a /48 route to the Tailscale ULA, since that will fail as a dupe.
