Brad Fitzpatrick	6b71568eb7	util/cloudenv: add Azure support & DNS IPs And rewrite cloud detection to try to do only zero or one metadata discovery request for all clouds, only doing a first (or second) as confidence increases. Work remains for Windows, but a start. And add Cloud to tailcfg.Hostinfo, which helped with testing using "tailcfg debug hostinfo".

Mihai Parparita	ec649e707f	ipn/ipnlocal: prefer to use one CGNAT route on the Mac Together with `06aa141632` this minimizes the number of NEPacketTunnelNetworkSettings updates that we have to do, and thus avoids Chrome interrupting outstanding requests due to (perceived) network changes.

Aaron Bieber	3f4fd64311	cmd/tailscale: exit loop when timeout and pingArgs.num are met Currently if you use '-c' and ping a host that times out, ping will continue running indefinitely. This change exits the loop with "no reply" when we time out, hit the value specified by '-c' and do not have anyPong. If we have anyPong it returns nil.

Brad Fitzpatrick	aa37aece9c	ipn/ipnlocal, net/dns, util/cloudenv: add AWS DNS support And remove the GCP special-casing from ipn/ipnlocal; do it only in the forwarder for .internal. Fixes #4980 Fixes #4981 Change-Id: I5c481e96d91f3d51d274a80fbd37c38f16dfa5cb Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	88c2afd1e3	ipn/ipnlocal, net/dns, util/cloudenv: specialize DNS config on Google Cloud This does three things: If you're on GCP, it adds a .internal DNS split route to the metadata server, so we never break GCP DNS names. This lets people have some Tailscale nodes on GCP and some not (e.g. laptops at home) without having to add a Tailnet-wide .internal DNS route. If you already have such a route, though, it won't overwrite it. * If the 100.100.100.100 DNS forwarder has nowhere to forward to, it forwards it to the GCP metadata IP, which forwards to 8.8.8.8. This means there are never errNoUpstreams ("upstream nameservers not set") errors on GCP due to e.g. mangled /etc/resolv.conf (GCP default VMs don't have systemd-resolved, so it's likely a DNS supremacy fight) * makes the DNS fallback mechanism use the GCP metadata IP as a fallback before our hosted HTTP-based fallbacks I created a default GCP VM from their web wizard. It has no systemd-resolved. I then made its /etc/resolv.conf be empty and deleted its GCP hostnames in /etc/hosts. I then logged in to a tailnet with no global DNS settings. With this, tailscaled writes /etc/resolv.conf (direct mode, as no systemd-resolved) and sets it to 100.100.100.100, which then has regular DNS via the metadata IP and .internal DNS via the metadata IP as well. If the tailnet configures explicit DNS servers, those are used instead, except for .internal. This also adds a new util/cloudenv package based on version/distro where the cloud type is only detected once. We'll likely expand it in the future for other clouds, doing variants of this change for other popular cloud environments.

But it only had one line anyway, so move it here to avoid the intermediate layer's published permissions problem entirely. Also optimize the cachability a bit while here.

Mihai Parparita	06aa141632	wgengine/router: avoid unncessary routing configuration changes The iOS and macOS networking extension API only exposes a single setter for the entire routing and DNS configuration, and does not appear to do any kind of diffing or deltas when applying changes. This results in spurious "network changed" errors in Chrome, even when the `OneCGNATRoute` flag from `df9ce972c7` is used (because we're setting the same configuration repeatedly). Since we already keep track of the current routing and DNS configuration in CallbackRouter, use that to detect if they're actually changing, and only invoke the platform setter if it's actually necessary.

Brad Fitzpatrick	3b1f99ded1	ssh/tailssh: fix Tailscale SSH to Linux Arch machines See https://github.com/tailscale/tailscale/issues/4924#issuecomment-1168201823 Arch uses a different login binary that makes the -h flag set the PAM service to "remote". So if they don't have that configured, don't pass -h. Thanks to @eddiezane for debugging!

Aaron Klotz	4baf34cf25	net/dns: set appropriate Windows registry values to prevent it from sending DNS changes concerning our interface to AD domain controllers. We do this unconditionally inside SetDNS such that the values are always set before we make any other changes to DNS configurations. It should not be harmful for the settings to remain even when other DNS settings are cleared out (since they only affect our network interface). See https://docs.microsoft.com/en-us/troubleshoot/windows-server/networking/configure-dns-dynamic-updates-windows-server-2003 for details about the registry value.

Aaron Klotz	8cdfd12977	net/dns: update Windows split DNS settings to work alongside other NRPT entries set by group policy. When there are group policy entries for the NRPT that do not belong to Tailscale, we recognize that we need to add ourselves to group policy and use that registry key instead of the local one. We also refresh the group policy settings as necessary to ensure that our changes take effect immediately.

James Tucker	76256d22d8	wgengine/router: windows: set SkipAsSource on IPv6 LL addresses Link-local addresses on the Tailscale interface are not routable. Ideally they would be removed, however, a concern exists that the operating system will attempt to re-add them which would lead to thrashing. Setting SkipAsSource attempts to avoid production of packets using the address as a source in any default behaviors. Before, in powershell: `ping (hostname)` would ping the link-local address of the Tailscale interface, and fail. After: `ping (hostname)` now pings the link-local address on the next highest priority metric local interface. Fixes #4647 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
