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.

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.

David Anderson	19eca34f47	wgengine/router: fix FreeBSD configuration failure on the v6 /48.

Brad Fitzpatrick	2d96215d97	wgengine/router: make Linux delRoute idempotent, cidrDiff fail late as possible This makes cidrDiff do as much as possible before failing, and makes a delete of an already-deleted rule be a no-op. We should never do this ourselves, but other things on the system can, and this should help us recover a bit. Also adds the start of root-requiring tests. TODO: hook into wgengine/monitor and notice when routes are changed behind our back, and invalidate our routes map and re-read from kernel (via the ip command) at least on the next reconfig call.

David Anderson	267531e4f8	wgengine/router: probe better for v6 policy routing support. Previously we disabled v6 support if the disable_policy knob was missing in /proc, but some kernels support policy routing without exposing the toggle.

Brad Fitzpatrick	01ee638cca	Change some os.IsNotExist to errors.Is(err, os.ErrNotExist) for non-os errors. os.IsNotExist doesn't unwrap errors. errors.Is does. The ioutil.ReadFile ones happened to be fine but I changed them so we're consistent with the rule: if the error comes from os, you can use os.IsNotExist, but from any other package, use errors.Is. (errors.Is always would also work, but not worth updating all the code) The motivation here was that we were logging about failure to migrate legacy relay node prefs file on startup, even though the code tried to avoid that.

David Anderson	68ddf134d7	wgengine/router/dns: issue ipconfig /registerdns when applying DNS settings. Amazingly, there doesn't seem to be a documented way of updating network configuration programmatically in a way that Windows takes notice of. The naturopathic remedy for this is to invoke ipconfig /registerdns, which does a variety of harmless things and also invokes the private API that tells windows to notice new adapter settings. This makes our DNS config changes stick within a few seconds of us setting them. If we're invoking a shell command anyway, why futz with the registry at all? Because netsh has no command for changing the DNS suffix list, and its commands for setting resolvers requires parsing its output and keeping track of which server is in what index. Amazingly, twiddling the registry directly is the less painful option. Fixes #853. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
