Xe Iaso	d6b8a18b09	cmd/proxy-to-grafana: use localClient.GetCertificate (#5024 ) Closes #5023 Signed-off-by: Xe <xe@tailscale.com>	2 years ago
Xe Iaso	5bb44a4a5c	cmd/gitops-pusher: correctly handle ACL tests failing (#5016 ) Apparently the API for running ACL tests returns a 200 if the ACL tests fail. This is weird, but we can handle it. Signed-off-by: Xe <xe@tailscale.com>	2 years ago
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". Updates #4983 (Linux only) Updates #4984 Change-Id: Ib03337089122ce0cb38c34f724ba4b4812bc614e Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
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.

Xe Iaso	dee95d0894	cmd/gitops-pusher: add new GitOps assistant (#4893 ) This is for an upcoming blogpost on how to manage Tailscale ACLs using a GitOps flow. This tool is intended to be used in CI and will allow users to have a git repository be the ultimate source of truth for their ACL file. This enables ACL changes to be proposed, approved and discussed before they are applied. Signed-off-by: Xe <xe@tailscale.com>	2 years ago

Maisem Ali	67325d334e	cmd/tailscale/cli: add lose-ssh risk This makes it so that the user is notified that the action they are about to take may result in them getting disconnected from the machine. It then waits for 5s for the user to maybe Ctrl+C out of it. It also introduces a `--accept-risk=lose-ssh` flag for automation, which allows the caller to pre-acknowledge the risk. The two actions that cause this are: - updating `--ssh` from `true` to `false` - running `tailscale down` Updates #3802 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago

Aaron Klotz	b005b79236	net/dns, paths, util/winutil: change net/dns/windowsManager NRPT management to support more than 50 domains. AFAICT this isn't documented on MSDN, but based on the issue referenced below, NRPT rules are not working when a rule specifies > 50 domains. This patch modifies our NRPT rule generator to split the list of domains into chunks as necessary, and write a separate rule for each chunk. For compatibility reasons, we continue to use the hard-coded rule ID, but as additional rules are required, we generate new GUIDs. Those GUIDs are stored under the Tailscale registry path so that we know which rules are ours. I made some changes to winutils to add additional helper functions in support of both the code and its test: I added additional registry accessors, and also moved some token accessors from paths to util/winutil.

Aaron Klotz	d915e0054c	cmd/tailscaled: change Windows service shutdown and add optional event logging Once a stop request is received and the service updates its status to `svc.StopPending`, it should continue running until the shutdown sequence is complete, and then return out of `(*ipnService).Execute`, which automatically sends a `svc.Stopped` notification to Windows. To make this happen, I changed the loop so that it runs until `doneCh` is closed, and then returns. I also removed a spurious `svc.StopPending` notification that the Windows Service Control Manager might be interpreting as a request for more time to shut down. Finally, I added some optional logging that sends a record of service notifications to the Windows event log, allowing us to more easily correlate with any Service Control Manager errors that are sent to the same log.
