Joe Tsai	32a1a3d1c0	util/deephash: avoid variadic argument for Update (#5372 ) Hashing []any is slow since hashing of interfaces is slow. Hashing of interfaces is slow since we pessimistically assume that cycles can occur through them and start cycle tracking. Drop the variadic signature of Update and fix callers to pass in an anonymous struct so that we are hashing concrete types near the root of the value tree.

Tom DNetto	9e77660931	net/tstun,wgengine/{.,netstack}: handle UDP magicDNS traffic in netstack This change wires netstack with a hook for traffic coming from the host into the tun, allowing interception and handling of traffic to quad-100. With this hook wired, magicDNS queries over UDP are now handled within netstack. The existing logic in wgengine to handle magicDNS remains for now, but its hook operates after the netstack hook so the netstack implementation takes precedence. This is done in case we need to support platforms with netstack longer than expected. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago
Tom DNetto	dc71d3559f	net/tstun,wgengine: split PreFilterOut into multiple hooks A subsequent commit implements handling of magicDNS traffic via netstack. Implementing this requires a hook for traffic originating from the host and hitting the tun, so we make another hook to support this. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 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>	2 years ago
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.

Denton Gentry	878a20df29	net/dns: add GetBaseConfig to CallbackRouter. Allow users of CallbackRouter to supply a GetBaseConfig implementation. This is expected to be used on Android, which currently lacks both a) platform support for Split-DNS and b) a way to retrieve the current DNS servers. iOS/macOS also use the CallbackRouter but have platform support for SplitDNS, so don't need getBaseConfig.

Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.
