Sonia Appasamy	258f16f84b	ipn/ipnlocal: add tailnet MagicDNS name to ipn.LoginProfile Start backfilling MagicDNS suffixes on LoginProfiles. Updates #9286 Signed-off-by: Sonia Appasamy <sonia@tailscale.com>	1 year ago
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).

Maisem Ali	d06a75dcd0	ipn/ipnlocal: fix deadlock in resetControlClientLocked resetControlClientLocked is called while b.mu was held and would call cc.Shutdown which would wait for the observer queue to drain. However, there may be active callbacks from cc already waiting for b.mu resulting in a deadlock. This makes it so that resetControlClientLocked does not call Shutdown, and instead just returns the value. It also makes it so that any status received from previous cc are ignored.

Maisem Ali	96277b63ff	ipn/ipnlocal: rename LogoutSync to Logout Updates #cleanup Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	959362a1f4	ipn/ipnlocal,control/controlclient: make Logout more sync We already removed the async API, make it more sync and remove the FinishLogout state too. This also makes the callback be synchronous again as the previous attempt was trying to work around the logout callback resulting in a client shutdown getting blocked forever.

Brad Fitzpatrick	7053e19562	control/controlclient: delete Status.Log{in,out}Finished They were entirely redundant and 1:1 with the status field so this turns them into methods instead.

Brad Fitzpatrick	55bb7314f2	control/controlclient: replace a status func with Observer interface For now the method has only one interface (the same as the func it's replacing) but it will grow, eventually with the goal to remove the controlclient.Status type for most purposes.

Will Norris	57a008a1e1	all: pass log IDs as the proper type rather than strings This change focuses on the backend log ID, which is the mostly commonly used in the client.

Maisem Ali	0fd2f71a1e	ipn/ipnlocal: use presence of NodeID to identify logins The profileManager was using the LoginName as a proxy to figure out if the profile had logged in, however the LoginName is not present if the node was created with an Auth Key that does not have an associated user.

Maisem Ali	dd50dcd067	ipn/ipnlocal: handle untagging nodes better We would end up with duplicate profiles for the node as the UserID would have chnaged. In order to correctly deduplicate profiles, we need to look at both the UserID and the NodeID. A single machine can only ever have 1 profile per NodeID and 1 profile per UserID. Note: UserID of a Node can change when the node is tagged/untagged, and the NodeID of a device can change when the node is deleted so we need to check for both.

Maisem Ali	6afe26575c	ipn: make Notify.Prefs be a *ipn.PrefsView It is currently a `ipn.PrefsView` which means when we do a JSON roundtrip, we go from an invalid Prefs to a valid one.

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.

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.

Josh Bleecher Snyder	07c09f470d	ipn/ipnlocal: do not shut down the backend halfway through TestStateMachine LocalBackend.Shutdown's docs say: > The backend can no longer be used after Shutdown returns. Nevertheless, TestStateMachine blithely calls Shutdown, talks some smack, and continues on, expecting things to work. Other uses of Shutdown in the codebase are as intended. Things mostly kinda work anyway, except that the wgengine.Engine has been shut down, so calls to Reconfig fail. Those get logged: > local.go:603: wgengine status error: engine closing; no status but otherwise ignored. However, the Reconfig failure caused one fewer call to pause/unpause than normal. Now the assertCalls lines match the equivalent ones earlier in the test. I don't see an obvious correct replacement for Shutdown in the context of this test; I'm not sure entirely what it is trying to accomplish. It is possible that many of the tests remaining after the prior call to Shutdown are now extraneous. They don't harm anything, though, so err on the side of safety and leave them for now.

Josh Bleecher Snyder	b681edc572	ipn/ipnlocal: add failing test Concurrent calls to LocalBackend.setWgengineStatus could result in some of the status updates being dropped. This was exacerbated by `92077ae78c`, which increases the probability of concurrent status updates, causing test failures (tailscale/corp#2579). It's going to take a bit of work to fix this test. The ipnlocal state machine is difficult to reason about, particularly in the face of concurrency. We could fix the test trivially by throwing a new mutex around setWgengineStatus to serialize calls to it, but I'd like to at least try to do better than cosmetics. In the meantime, commit the test.
