Brad Fitzpatrick	aef3c0350c	control/controlclient: break direct.go into map.go (+tests), add mapSession ... So the NetworkMap-from-incremental-MapResponses can be tested easily. And because direct.go was getting too big. No change in behavior at this point. Just movement. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	670838c45f	tailcfg, control/controlclient: (mapver 16) add Node.Online, MapResponse.OnlineChange ... And fix PeerSeenChange bug where it was ignored unless there were other peer changes. Updates tailscale/corp#1574 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	7055f870f8	control/controlclient: only use a single DNS label as the hostname. ... Fixes #971 Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
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. (despite negligible increase in client->control bandwidth) Updates tailscale/corp#1543 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Adrian Dewhurst	3f456ba2e7	control/controlclient: return correct certificate ... When searching for the matching client identity, the returned certificate chain was accidentally set to that of the last identity returned by the certificate store instead of the one corresponding to the selected identity. Also, add some extra error checking for invalid certificate chains, just in case. Signed-off-by: Adrian Dewhurst <adrian@tailscale.com>	4 years ago

Brad Fitzpatrick	1bd14a072c	cmd/tailscale, ipn/localapi: move IP forwarding check to tailscaled, API ... Instead of having the CLI check whether IP forwarding is enabled, ask tailscaled. It has a better idea. If it's netstack, for instance, the sysctl values don't matter. And it's possible that only the daemon has permission to know. Fixes #1626 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	a998fe7c3d	control/controlclient: support lazy machine key generation ... It's not done in the caller yet, but the controlclient does it now. Updates #1573 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	12ae2d73b3	control/controlclient: fix TS_DEBUG_MAP on requests ... The concrete type being encoded changed from a value to pointer earlier and this was never adjusted. (People don't frequently use TS_DEBUG_MAP to see requests, so it went unnoticed until now.) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
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	0a02aaf813	control, ipn, tailcfg: remove golang.org/x/oauth2 dep, add tailcfg.Oauth2Token ... golang.org/x/oauth2 pulls in App Engine and grpc module dependencies, screwing up builds that depend on this module. Some background on the problem: https://go.googlesource.com/proposal/+/master/design/36460-lazy-module-loading.md Fixes tailscale/corp#1471 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	cc508be603	control/controlclient: remove redundant Hostinfo log ... The direct client already logs it in JSON form. Then it's immediately logged again in an unformatted dump, so this removes that unformatted one. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	6fbc9b3a98	control/controlclient: cache Windows version ... To atone for 1d7f9d5b4a, the revert of 4224b3f731. At least it's fast again, even if it's shelling out to cmd.exe (once now). Updates #1478 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	f45a9e291b	tailcfg, control/controlclient: add MapResponse.PingRequest ... So the control server can test whether a client's actually present. Most clients are over HTTP/2, so these pings (to the same host) are super cheap. This mimics the earlier goroutine dump mechanism. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	ddfcc4326c	types/persist: split controlclient.Persist into a small leaf package ... This one alone doesn't modify the global dependency map much (depaware.txt if anything looks slightly worse), but it leave controlclient as only containing NetworkMap: bradfitz@tsdev:~/src/tailscale.com/ipn$ grep -F "controlclient." *.go backend.go: NetMap *controlclient.NetworkMap // new netmap received fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) handle.go: netmapCache *controlclient.NetworkMap handle.go:func (h *Handle) NetMap() *controlclient.NetworkMap { Once that goes into a leaf package, then ipn doesn't depend on controlclient at all, and then the client gets smaller.

Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go ... This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Sonia Appasamy	4dab0c1702	tailcfg: update node display name fields and methods (#1207) ...
