Brad Fitzpatrick	d488678fdc	cmd/tailscaled, wgengine{,/netstack}: add netstack hybrid mode, add to Windows For #707 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	1f99f889e1	ipn/{ipnlocal,localapi}: add localapi handler to dial/proxy file PUTs Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	bc4381447f	net/tstun: return the real interface name at device creation. This is usually the same as the requested interface, but on some unixes can vary based on device number allocation, and on Windows it's the GUID instead of the pretty name, since everything relating to configuration wants the GUID.

Josh Bleecher Snyder	b3ceca1dd7	wgengine/...: split into multiple receive functions Upstream wireguard-go has changed its receive model. NewDevice now accepts a conn.Bind interface. The conn.Bind is stateless; magicsock.Conns are stateful. To work around this, we add a connBind type that supports cheap teardown and bring-up, backed by a Conn. The new conn.Bind allows us to specify a set of receive functions, rather than having to shoehorn everything into ReceiveIPv4 and ReceiveIPv6. This lets us plumbing DERP messages directly into wireguard-go, instead of having to mux them via ReceiveIPv4. One consequence of the new conn.Bind layer is that closing the wireguard-go device is now indistinguishable from the routine bring-up and tear-down normally experienced by a conn.Bind. We thus have to explicitly close the magicsock.Conn when the close the wireguard-go device. One downside of this change is that we are reliant on wireguard-go to call receiveDERP to process DERP messages. This is fine for now, but is perhaps something we should fix in the future.

David Anderson	f77ba75d6c	wgengine/router: move DNS cleanup into the DNS package. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	39b9ab3522	cmd/tailscaled: rename isUserspace to useNetstack The bool was already called useNetstack at the caller. isUserspace (to mean netstack) is confusing next to wgengine.NewUserspaceEngine, as that's a different type of 'userspace'. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	90f82b6946	net/dns/resolver: add live reconfig, plumb through to ipnlocal. The resolver still only supports a single upstream config, and ipn/wgengine still have to split up the DNS config, but this moves closer to unifying the DNS configs. As a handy side-effect of the refactor, IPv6 MagicDNS records exist now. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	41e4e02e57	net/{packet,tstun}: send peerapi port in TSMP pongs For discovery when an explicit hostname/IP is known. We'll still also send it via control for finding peers by a list. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	0fb738760f	wgengine: make Tun optional again, default to fake. This makes setup more explicit in prod codepaths, without requiring a bunch of arguments or helpers for tests and userspace mode. Signed-off-by: David Anderson <danderson@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	c0cdca6d06	cmd/tailscaled, logtail: share link monitor from wgengine to logtail Part of overall effort to clean up, unify, use link monitoring more, and make Tailscale quieter when all networks are down. This is especially bad on macOS where we can get killed for not being polite it seems. (But we should be polite in any case) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	e3df29d488	wgengine{,/monitor}: move interface state fetching/comparing to monitor Gets it out of wgengine so the Engine isn't responsible for being a callback registration hub for it. This also removes the Engine.LinkChange method, as it's no longer necessary. The monitor tells us about changes; it doesn't seem to need any help. (Currently it was only used by Swift, but as of `14dc790137` we just do the same from Go) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	38dc6fe758	cmd/tailscaled, wgengine: remove --fake, replace with netstack And add a --socks5-server flag.

Brad Fitzpatrick	dda03a911e	wgengine/monitor: change API to permit multiple independent callbakcks Currently it assumes exactly 1 registered callback. This changes it to support 0, 1, or more than 1. This is a step towards plumbing wgengine/monitor into more places (and moving some of wgengine's interface state fetching into monitor in a later step) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
