Brad Fitzpatrick	3ae701f0eb	net/tsaddr, wgengine/netstack: add IPv6 range that forwards to site-relative IPv4 This defines a new magic IPv6 prefix, fd7a:115c:a1e0:b1a::/64, a subset of our existing /48, where the final 32 bits are an IPv4 address, and the middle 32 bits are a user-chosen "site ID". (which must currently be 0000:00xx; the top 3 bytes must be zero for now) e.g., I can say my home LAN's "site ID" is "0000:00bb" and then advertise its 10.2.0.0/16 IPv4 range via IPv6, like: tailscale up --advertise-routes=fd7a:115c:a1e0:b1a::bb:10.2.0.0/112 (112 being /128 minuse the /96 v6 prefix length) Then people in my tailnet can: $ curl '[fd7a:115c:a1e0:b1a::bb:10.2.0.230]' <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ....

David Eger	f992749b98	cmd/tailscale: Add file get --loop flag. To "automatically receive taildrop files to my Downloads directory," user currently has to run 'tailscale file get' in a loop.

James Tucker	f4aad61e67	wgengine/monitor: ignore duplicate RTM_NEWADDRs Ignoring the events at this layer is the simpler path for right now, a broader change should follow to suppress irrelevant change events in a higher layer so as to avoid related problems with other monitoring paths on other platforms. This approach may also carry a small risk that it applies an at-most-once invariant low in the chain that could be assumed otherwise higher in the code. I adjusted the newAddrMessage type to include interface index rather than a label, as labels are not always supplied, and in particular on my test hosts they were consistently missing for ipv6 address messages. I adjusted the newAddrMessage.Addr field to be populated from Attributes.Address rather than Attributes.Local, as again for ipv6 .Local was always empty, and with ipv4 the .Address and .Local contained the same contents in each of my test environments.

Tom DNetto	8f6d8cf979	tstest/integration/vms: test on stable nixos (21.11) I would like to do some more customized integration tests in the future, (specifically, bringing up a mitm proxy and testing tailscaled through that) so hoping to bring back the nixos wiring to support that.

Tom DNetto	f923ce6f87	shell.nix: use tailscale-go for compilation This change builds a derivation for tailscale-go and makes it available in the users development environment. This is consistent with the shell.nix in corp/. Once go1.18 is in a stable Nixpkgs release we can avoid relying on derivations from nixpkgs head. For now, this works well, and the fetched derivations are cached in the Nix store according to the usual rules. Fixes #4231 Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Tom	24bdcbe5c7	net/dns, net/dns/resolver, wgengine: refactor DNS request path (#4364 ) * net/dns, net/dns/resolver, wgengine: refactor DNS request path Previously, method calls into the DNS manager/resolver types handled DNS requests rather than DNS packets. This is fine for UDP as one packet corresponds to one request or response, however will not suit an implementation that supports DNS over TCP. To support PRs implementing this in the future, wgengine delegates all handling/construction of packets to the magic DNS endpoint, to the DNS types themselves. Handling IP packets at this level enables future support for both UDP and TCP. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago

James Tucker	2550acfd9d	go.mod: bump netstack for clone reset fix (#4379 ) In tracking down issue #4144 and reading through the netstack code in detail, I discovered that the packet buf Clone path did not reset the packetbuf it was getting from the sync.Pool. The fix was sent upstream https://github.com/google/gvisor/pull/7385, and this bump pulls that in. At this time there is no known path that this fixes, however at the time of upstream submission this reset at least one field that could lead to incorrect packet routing if exercised, a situation that could therefore lead to an information leak.

David Anderson	f570372b4d	control/controlbase: don't enforce a max protocol version at handshake time. Doing so makes development unpleasant, because we have to first break the client by bumping to a version the control server rejects, then upgrade the control server to make it accept the new version. This strict rejection at handshake time is only necessary if we want to blocklist some vulnerable protocol versions in the future. So, switch to a default-permissive stance: until we have such a version that we have to eagerly block early, we'll accept whatever version the client presents, and leave it to the user of controlbase.Conn to make decisions based on that version. Noise still enforces that the client and server agree on what protocol version is being used, and the control server still has the option to finish the handshake and then hang up with an in-noise error, rather than abort at the handshake level.

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.

Maisem Ali	6fecc16c3b	ipn/ipnlocal: do not process old status messages received out of order When `setWgengineStatus` is invoked concurrently from multiple goroutines, it is possible that the call invoked with a newer status is processed before a call with an older status. e.g. a status that has endpoints might be followed by a status without endpoints. This causes unnecessary work in the engine and can result in packet loss. This patch adds an `AsOf time.Time` field to the status to specifiy when the status was calculated, which later allows `setWgengineStatus` to ignore any status messages it receives that are older than the one it has already processed.
