Brad Fitzpatrick	546506a54d	ipn/ipnlocal: add a test for recent WhoIs regression This would've prevented #9470. This used to pass, fails as of `9538e9f970`, and passes again once #9472 is in.

James Tucker	d52ab181c3	Revert "ipn/ipnlocal: allow Split-DNS and default resolvers with WireGuard nodes" This reverts commit `c7ce4e07e5`. Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
James Tucker	c7ce4e07e5	ipn/ipnlocal: allow Split-DNS and default resolvers with WireGuard nodes The initial implementation directly mirrored the behavior of Tailscale exit nodes, where the WireGuard exit node DNS took precedence over other configuration. This adjusted implementation treats the WireGuard DNS resolvers as a lower precedence default resolver than the tailnet default resolver, and allows split DNS configuration as well. This also adds test coverage to the existing DNS selection behavior with respect to default resolvers and split DNS routes for Tailscale exit nodes above cap 25. There may be some refinement to do in the logic in those cases, as split DNS may not be working as we intend, though that would be a pre-existing and separate issue.

Brad Fitzpatrick	0d991249e1	types/netmap: remove NetworkMap.{Addresses,MachineStatus} And convert all callers over to the methods that check SelfNode. Now we don't have multiple ways to express things in tests (setting fields on SelfNode vs NetworkMap, sometimes inconsistently) and don't have multiple ways to check those two fields (often only checking one or the other).

Brad Fitzpatrick	9538e9f970	ipn/ipnlocal: keep internal map updated of latest Nodes post mutations We have some flaky integration tests elsewhere that have no one place to ask about the state of the world. This makes LocalBackend be that place (as it's basically there anyway) but doesn't yet add the ForTest accessor method. This adds a LocalBackend.peers map[NodeID]NodeView that is incrementally updated as mutations arrive. And then we start moving away from using NetMap.Peers at runtime (UpdateStatus no longer uses it now). And remove another copy of NodeView in the LocalBackend nodeByAddr map. Change that to point into b.peers instead. Future changes will then start streaming whole-node-granularity peer change updates to WatchIPNBus clients, tracking statefully per client what each has seen. This will get the GUI clients from receiving less of a JSON storm of updates all the time.

Marwan Sulaiman	50990f8931	ipn, ipn/ipnlocal: add Foreground field for ServeConfig This PR adds a new field to the serve config that can be used to identify which serves are in "foreground mode" and then can also be used to ensure they do not get persisted to disk so that if Tailscaled gets ungracefully shutdown, the reloaded ServeConfig will not have those ports opened.

salman	eec734a578	ipn/{ipnlocal,localapi}: ensure watcher is installed before /watch-ipn-bus/ responds with 200 This change delays the first flush in the /watch-ipn-bus/ handler until after the watcher has been successfully installed on the IPN bus. It does this by adding a new onWatchAdded callback to LocalBackend.WatchNotifications(). Without this, the endpoint returns a 200 almost immediatly, and only then installs a watcher for IPN events. This means there's a small window where events could be missed by clients after calling WatchIPNBus(). Fixes tailscale/corp#8594. Signed-off-by: salman <salman@tailscale.com>	2 years ago

Maisem Ali	50b4b8b2c6	ipn/ipnlocal: make peerIPs return a sorted slice Currently peerIPs doesn't do any sorting of the routes it returns. This is typically fine, however imagine the case of an HA subnet router failover. When a route R moves from peer A to peer B, the output of peerIPs changes. This in turn causes all the deephash check inside wgengine to fail as the hashed value of [R1, R2] is different than the hashed value of [R2, R1]. When the hash check failes, it causes wgengine to reconfigure all routes in the OS. This is especially problematic for macOS and iOS where we use the NetworkExtension. This commit makes it that the peerIPs are always sorted when returned, thus making the hash be consistent as long as the list of routes remains static.

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.

Avery Pennarun	b7e31ab1a4	ipn: mock controlclient.Client; big ipn.Backend state machine test. A very long unit test that verifies the way the controlclient and ipn.Backend interact. This is a giant sequential test of the state machine. The test passes, but only because it's asserting all the wrong behaviour. I marked all the behaviour I think is wrong with BUG comments, and several additional test opportunities with TODO. Note: the new test supercedes TestStartsInNeedsLoginState, which was checking for incorrect behaviour (although the new test still checks for the same incorrect behaviour) and assumed .Start() would converge before returning, which it happens to do, but only for this very specific case, for the current implementation.
