Brad Fitzpatrick	5b3f5eabb5	control/controlclient: fix leaked http2 goroutines on shutdown If a noise dial was happening concurrently with shutdown, the http2 goroutines could leak.

Claire Wang	a17c45fd6e	control: use tstime instead of time (#8595 ) Updates #8587 Signed-off-by: Claire Wang <claire@tailscale.com>	1 year ago
Maisem Ali	9d1a3a995c	control/controlclient: use ctx passed down to NoiseClient.getConn Without this, the client would just get stuck dialing even if the context was canceled. Updates tailscale/corp#12590 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Andrew Dunham	42fd964090	control/controlclient: use dnscache.Resolver for Noise client This passes the *dnscache.Resolver down from the Direct client into the Noise client and from there into the controlhttp client. This retains the Resolver so that it can share state across calls instead of creating a new resolver. Updates #4845 Updates #6110 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: Ia5d6af1870f3b5b5d7dd5685d775dcf300aec7af	2 years ago
Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Maisem Ali	a413fa4f85	control/controlclient: export NoiseClient This allows reusing the NoiseClient in other repos without having to reimplement the earlyPayload logic. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Brad Fitzpatrick	910db02652	client/tailscale, tsnet, ipn/ipnlocal: prove nodekey ownership over noise Fixes #5972 Change-Id: Ic33a93d3613ac5dbf172d6a8a459ca06a7f9e547 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	988c1f0ac7	control/controlclient, tailcfg: add support for EarlyNoise payload before http/2 Not yet used, but skipped over, parsed, and tested. Updates #5972 Change-Id: Icd00196959ce266ae16a6c9244bd5e458e2c2947 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	120bfc97ce	control/controlclient: refactor noiseClient, connections, http2 In prep for stateful http2 noise connections. Updates #5972 Change-Id: I9ebecc3b2d5d193621b87d39b506f231d6c82145 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	246274b8e9	control/controlhttp: allow setting, getting Upgrade headers in Noise upgrade Not currently used, but will allow us to usually remove a round-trip for a future feature. Updates #5972 Change-Id: I2770ea28e3e6ec9626d1cbb505a38ba51df7fba2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	6d04184325	control/controlclient: add a noiseClient.post helper method In prep for a future change that would've been very copy/paste-y. And because the set-dns call doesn't currently use a context, so timeouts/cancelations are plumbed. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Andrew Dunham	e1bdbfe710	tailcfg, control/controlhttp, control/controlclient: add ControlDialPlan field (#5648 ) * tailcfg, control/controlhttp, control/controlclient: add ControlDialPlan field This field allows the control server to provide explicit information about how to connect to it; useful if the client's link status can change after the initial connection, or if the DNS settings pushed by the control server break future connections.

Andrew Dunham	9b71008ef2	control/controlhttp: move Dial options into options struct (#5661 ) This turns 'dialParams' into something more like net.Dialer, where configuration fields are public on the struct. Split out of #5648 Change-Id: I0c56fd151dc5489c3c94fb40d18fd639e06473bc Signed-off-by: Andrew Dunham <andrew@tailscale.com>	2 years ago

Maisem Ali	5a1ef1bbb9	net/tsdial: add SystemDial as a wrapper on netns.Dial The connections returned from SystemDial are automatically closed when there is a major link change. Also plumb through the dialer to the noise client so that connections are auto-reset when moving from cellular to WiFi etc. Updates #3363 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Brad Fitzpatrick	910ae68e0b	util/mak: move tailssh's mapSet into a new package for reuse elsewhere Change-Id: Idfe95db82275fd2be6ca88f245830731a0d5aecf Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	02ad987e24	control/controlbase: make the protocol version number selectable. This is so that we can plumb our client capability version through the protocol as the Noise version. The capability version increments more frequently than strictly required (the Noise version only needs to change when cryptographically-significant changes are made to the protocol, whereas the capability version also indicates changes in non-cryptographically-significant parts of the protocol), but this gives us a safe pre-auth way to determine if the client supports future protocol features, while still relying on Noise's strong assurance that the client and server have agreed on the same version. Currently, the server executes the same protocol regardless of the version number, and just presents the version to the caller so they can do capability-based things in the upper RPC protocol. In future, we may add a ratchet to disallow obsolete protocols, or vary the Noise handshake behavior based on requested version.

Brad Fitzpatrick	c4f6df47e5	control/controlclient: fix Noise HTTP/2 regression from earlier commit Fix regression from `21069124db` caught by tests in another repo. The HTTP/2 Transport that was being returned had a ConnPool that never dialed.

Brad Fitzpatrick	21069124db	control/controlclient: fix the Noise HTTP/2 timeout config We want to close the connection after a minute of inactivity, not heartbeat once a minute to keep it alive forever.
