Jordan Whited	94415e8029	cmd/stunstamp: remove sqlite DB and API (#12604 ) stunstamp now sends data to Prometheus via remote write, and Prometheus can serve the same data. Retaining and cleaning up old data in sqlite leads to long probing pauses, and it's not worth investing more effort to optimize the schema and/or concurrency model.

Brad Fitzpatrick	3485e4bf5a	derp: make RunConnectionLoop funcs take Messages, support PeerPresentFlags PeerPresentFlags was added in `5ffb2668ef` but wasn't plumbed through to the RunConnectionLoop. Rather than add yet another parameter (as IP:port was added earlier), pass in the raw PeerPresentMessage and PeerGoneMessage struct values, which are the same things, plus two fields: PeerGoneReasonType for gone and the PeerPresentFlags from `5ffb2668ef`.

Fran Bull	7eb8a77ac8	appc: don't schedule advertisement of 0 routes When the store-appc-routes flag is on for a tailnet we are writing the routes more often than seems necessary. Investigation reveals that we are doing so ~every time we observe a dns response, even if this causes us not to advertise any new routes. So when we have no new routes, instead do not advertise routes. Fixes #12593 Signed-off-by: Fran Bull <fran@tailscale.com>	1 week ago

Brad Fitzpatrick	ded7734c36	derp: account for increased size of peerPresent messages in mesh updates sendMeshUpdates tries to write as much as possible without blocking, being careful to check the bufio.Writer.Available size before writes.

Andrea Gottardo	d6a8fb20e7	health: include DERP region name in bad derp notifications (#12530 ) Fixes tailscale/corp#20971 We added some Warnables for DERP failure situations, but their Text currently spits out the DERP region ID ("10") in the UI, which is super ugly. It would be better to provide the RegionName of the DERP region that is failing. We can do so by storing a reference to the last-known DERP map in the health package whenever we fetch one, and using it when generating the notification text. This way, the following message... > Tailscale could not connect to the relay server '10'. The server might be temporarily unavailable, or your Internet connection might be down. becomes: > Tailscale could not connect to the 'Seattle' relay server. The server might be temporarily unavailable, or your Internet connection might be down. which is a lot more user-friendly. Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	2 weeks ago
Andrea Gottardo	8eb15d3d2d	cli/netcheck: fail with output if we time out fetching a derpmap (#12528 ) Updates tailscale/corp#20969 Right now, when netcheck starts, it asks tailscaled for a copy of the DERPMap. If it doesn't have one, it makes a HTTPS request to controlplane.tailscale.com to fetch one. This will always fail if you're on a network with a captive portal actively blocking HTTPS traffic. The code appears to hang entirely because the http.Client doesn't have a Timeout set. It just sits there waiting until the request succeeds or fails. This adds a timeout of 10 seconds, and logs more details about the status of the HTTPS request. Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	2 weeks ago

This is used, between other, by the Kubernetes operator, who uses the ID to delete the device when resources need cleaning up and writes the FQDN and IPs on various kube resource statuses for visibility.
