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.

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	988c1f0ac7	control/controlclient, tailcfg: add support for EarlyNoise payload before http/2 ... Not yet used, but skipped over, parsed, and tested.

Brad Fitzpatrick	231b88cc51	control/controlclient: add start of noise+http2 upgrade test ... Basic HTTP/2-over-noise client test. To be fleshed out in subsequent commits that add more functionality to the noise client.

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.
