Adrian Dewhurst	6d6cf88d82	control/controlclient: use our fork of certstore ... The cyolosecurity fork of certstore did not update its module name and thus can only be used with a replace directive. This interferes with installing using `go install` so I created a tailscale fork with an updated module name. Signed-off-by: Adrian Dewhurst <adrian@tailscale.com>	4 years ago
Josh Bleecher Snyder	1ece91cede	go.mod: upgrade wireguard-windows, de-fork wireguard-go ... Pull in the latest version of wireguard-windows. Switch to upstream wireguard-go. This requires reverting all of our import paths. Unfortunately, this has to happen at the same time. The wireguard-go change is very low risk, as that commit matches our fork almost exactly. (The only changes are import paths, CI files, and a go.mod entry.) So if there are issues as a result of this commit, the first place to look is wireguard-windows changes.

Avery Pennarun	19c3e6cc9e	types/logger: rate limited: more hysteresis, better messages. ... - Switch to our own simpler token bucket, since x/time/rate is missing necessary stuff (can't provide your own time func; can't check the current bucket contents) and it's overkill anyway. - Add tests that actually include advancing time. - Don't remove the rate limit on a message until there's enough room to print at least two more of them. When we do, we'll also print how many we dropped, as a contextual reminder that some were previously lost. (This is more like how the Linux kernel does it.) - Reformat the [RATE LIMITED] messages to be shorter, and to not corrupt original message. Instead, we print the message, then print its format string. - Use %q instead of \"%s\", for more accurate parsing later, if the format string contained quotes.

Josh Bleecher Snyder	3c543c103a	wgengine/magicsock: unify initial bind and rebind ... We had two separate code paths for the initial UDP listener bind and any subsequent rebinds. IPv6 got left out of the rebind code. Rather than duplicate it there, unify the two code paths. Then improve the resulting code: * Rebind had nested listen attempts to try the user-specified port first, and then fall back to :0 if that failed. Convert that into a loop. * Initial bind tried only the user-specified port. Rebind tried the user-specified port and 0. But there are actually three ports of interest: The one the user specified, the most recent port in use, and 0. We now try all three in order, as appropriate. * In the extremely rare case in which binding to port 0 fails, use a dummy net.PacketConn whose reads block until close. This will keep the wireguard-go receive func goroutine alive. As a pleasant side-effect of this, if we decide that we need to resuscitate #1796, it will now be much easier.

David Anderson	25ce9885a2	net/dns: don't use NM+resolved for NM >=1.26.6. ... NetworkManager fixed the bug that forced us to use NetworkManager if it's programming systemd-resolved, and in the same release also made NetworkManager ignore DNS settings provided for unmanaged interfaces... Which breaks what we used to do. So, with versions 1.26.6 and above, we MUST NOT use NetworkManager to indirectly program systemd-resolved, but thankfully we can talk to resolved directly and get the right outcome.

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	90f82b6946	net/dns/resolver: add live reconfig, plumb through to ipnlocal. ...

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.
