Brad Fitzpatrick	9f1dd716e8	tailcfg, logtail: provide Debug bit to disable logtail ... For people running self-hosted control planes who want a global opt-out knob instead of running their own logcatcher.

Brad Fitzpatrick	e96dd00652	ipn/ipnlocal: add capability for debugging peers over peerapi ... The default is still users can debug their own nodes. But like cd916b728b did, this adds support for admins to grant additional capabilities with the new tailcfg.CapabilityDebugPeer cap. Updates #4217 Change-Id: Ifce3d9a1f8e8845797970a4f97b393194663d35f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	cd916b728b	ipn/ipnlocal: add start of inter-user Taildrop ... Controlled by server-sent capability policy. To be initially used for SSH servers to record sessions to other nodes. Not yet productized into something user-accessible. (Notably, the list of Taildrop targets from the sender side isn't augmented yet.) This purely permits expanding the set of expands a node will accept a drop from.

Brad Fitzpatrick	d5f8f38ac6	tailcfg: rename map request version to "capability version" ... And add a CapabilityVersion type, primarily for documentation. This makes MapRequest.Version, RegisterRequest.Version, and SetDNSRequest.Version all use the same version, which will avoid confusing in the future if Register or SetDNS ever changed their semantics on Version change. (Currently they're both always 1) This will requre a control server change to allow a SetDNSRequest.Version value other than 1 to be deployed first.

Josh Bleecher Snyder	94fb42d4b2	all: use testingutil.MinAllocsPerRun ... There are a few remaining uses of testing.AllocsPerRun: Two in which we only log the number of allocations, and one in which dynamically calculate the allocations target based on a different AllocsPerRun run.

Brad Fitzpatrick	aae622314e	tailcfg, health: add way for control plane to add problems to health check ... So if the control plane knows that something's broken about the node, it can include problem(s) in MapResponse and "tailscale status" will show it. (and GUIs in the future, as it's in ipnstate.Status/JSON) This also bumps the MapRequest.Version, though it's not strictly required. Doesn't hurt.

Brad Fitzpatrick	34d2f5a3d9	tailcfg: add Endpoint, EndpointType, MapRequest.EndpointType ... Track endpoints internally with a new tailcfg.Endpoint type that includes a typed netaddr.IPPort (instead of just a string) and includes a type for how that endpoint was discovered (STUN, local, etc). Use []tailcfg.Endpoint instead of []string internally. At the last second, send it to the control server as the existing []string for endpoints, but also include a new parallel MapRequest.EndpointType []tailcfg.EndpointType, so the control server can start filtering out less-important endpoint changes from new-enough clients. Notably, STUN-discovered endpoints can be filtered out from 1.6+ clients, as they can discover them amongst each other via CallMeMaybe disco exchanges started over DERP. And STUN endpoints change a lot, causing a lot of MapResposne updates. But portmapped endpoints are worth keeping for now, as they they work right away without requiring the firewall traversal extra RTT dance. End result will be less control->client bandwidth.

Adrian Dewhurst	04dd6d1dae	control/controlclient: sign RegisterRequest (#1549) ... control/controlclient: sign RegisterRequest Some customers wish to verify eligibility for devices to join their tailnets using machine identity certificates. TLS client certs could potentially fulfill this role but the initial customer for this feature has technical requirements that prevent their use. Instead, the certificate is loaded from the Windows local machine certificate store and uses its RSA public key to sign the RegisterRequest message. There is room to improve the flexibility of this feature in future and it is currently only tested on Windows (although Darwin theoretically works too), but this offers a reasonable starting place for now.

Brad Fitzpatrick	0e3048d8e0	control/controlclient: support delta userprofiles from control ... I was going to make support for this advertised from the client, but turns out only "tailscale status" even uses the UserProfiles field and fails gracefully (omits that field) if a user profile for a user is missing, so I think we can just reuse the DeltaPeers field from the client to ask the control server to also delta encode the user profiles. For the few users running 1.1.x (unstable) versions between DeltaPeers support (1.1.82) and this (~1.1.541), they'll just sometimes have missing names in "tailscale status --json" or "tailscale status --web" (the only places the UserProfile is used).	4 years ago
