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.

ipn/ipnlocal: fix LocalBackend.WhoIs for self (#9472)
9538e9f970 broke LocalBackend.WhoIs
where you can no longer lookup yourself in WhoIs.
This occurs because the LocalBackend.peers map only contains peers.
If we fail to lookup a peer, double-check whether it is ourself.

Fixes #9470

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.

c08cf2a9c6 all: declare & plumb IPv6 masquerade address for peer
This PR plumbs through awareness of an IPv6 SNAT/masquerade address from the wire protocol
through to the low-level (tstun / wgengine). This PR is the first in two PRs for implementing
IPv6 NAT support to/from peers.

A subsequent PR will implement the data-plane changes to implement IPv6 NAT - this is just plumbing.

19a9d9037f tailcfg: add NodeCapMap
Like PeerCapMap, add a field to `tailcfg.Node` which provides
a map of Capability to raw JSON messages which are deferred to be
parsed later by the application code which cares about the specific
capabilities. This effectively allows us to prototype new behavior
without having to commit to a schema in tailcfg, and it also opens up
the possibilities to develop custom behavior in tsnet applications w/o
having to plumb through application specific data in the MapResponse.

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.

forever. The right thing to do here is to fix the LocalBackend
state machine but thats a different dumpster fire that we
are slowly making progress towards.

This makes it so that the SetControlClientStatus happens in a
different goroutine so that calls back into the auto client
do not block.

Also add a few missing mu.Unlocks in LocalBackend.Start.

ea4425d8a9 ipn/ipnlocal, wgengine/magicsock: move UpdateStatus stuff around
Upcoming work on incremental netmap change handling will require some
replumbing of which subsystems get notified about what. Done naively,
it could break "tailscale status --json" visibility later. To make sure
I understood the flow of all the updates I was rereading the status code
and realized parts of ipnstate.Status were being populated by the wrong
subsystems.

The engine (wireguard) and magicsock (data plane, NAT traveral) should
only populate the stuff that they uniquely know. The WireGuard bits
were fine but magicsock was populating stuff stuff that LocalBackend
could've better handled, so move it there.

4511e7d64e ipn/ipnstate: add PeerStatus.AltSharerUserID, stop mangling Node.User
In b987b2ab18 (2021-01-12) when we introduced sharing we mapped
the sharer to the userid at a low layer, mostly to fix the display of
"tailscale status" and the client UIs, but also some tests.

The commit earlier today, 7dec09d169, removed the 2.5yo option
to let clients disable that automatic mapping, as clearly we were never
getting around to it.

This plumbs the Sharer UserID all the way to ipnstatus so the CLI
itself can choose to print out the Sharer's identity over the node's
original owner.

Then we stop mangling Node.User and let clients decide how they want
to render things.

To ease the migration for the Windows GUI (which currently operates on
tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus),
a new method Node.SharerOrUser is added to do the mapping of
Sharer-else-User.

ipn/{ipnlocal,localapi}: actually renew certs before expiry (#8731)
While our `shouldStartDomainRenewal` check is correct, `getCertPEM`
would always bail if the existing cert is not expired. Add the same
`shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with
renewal when existing certs are still valid but should be renewed.

The extra check is expensive (ARI request towards LetsEncrypt), so cache
the last check result for 1hr to not degrade `tailscale serve`
performance.

Also, asynchronous renewal is great for `tailscale serve` but confusing
for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a
synchronous renewal for `tailscale cert`.

35bdbeda9f cli: introduce exit-node subcommand to list and filter exit nodes
This change introduces a new subcommand, `exit-node`, along with a

Exit nodes without location data will continue to be displayed when
`status` is used. Exit nodes with location data will only be displayed
behind `exit-node list`, and in status if they are the active exit node.

The `filter` flag can be used to filter exit nodes with location data by
country.

Exit nodes with Location.Priority data will have only the highest
priority option for each country and city listed. For countries with
multiple cities, a <Country> <Any> option will be displayed, indicating
the highest priority node within that country.

fe95d81b43 ipn/ipnlocal,wgengine/netstack: move LocalBackend specifc serving logic to LocalBackend
The netstack code had a bunch of logic to figure out if the LocalBackend should handle an
incoming connection and then would call the function directly on LocalBackend. Move that
logic to LocalBackend and refactor the methods to return conn handlers.

095d3edd33 ipn/ipnlocal: reenable profile tests on Windows
This fix does not seem ideal, but the test infrastructure using a local
goos doesn't seem to avoid all of the associated challenges, but is
somewhat deeply tied to the setup.

The core issue this addresses for now is that when run on Windows there
can be no code paths that attempt to use an invalid UID string, which on
Windows is described in [1].

For the goos="linux" tests, we now explicitly skip the affected
migration code if runtime.GOOS=="windows", and for the Windows test we
explicitly use the running users uid, rather than just the string
"user1". We also now make the case where a profile exists and has
already been migrated a non-error condition toward the outer API.

On some platforms (notably macOS and iOS) we look up the default
interface to bind outgoing connections to. This is both duplicated
work and results in logspam when the default interface is not available

more things that we will try to upload and fail).

Fixed by passing around a netmon.Monitor to more places, so that we can

90fd04cbde ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled
I realized that a lot of the problems that we're seeing around migration and
LocalBackend state can be avoided if we drive Windows pref migration entirely
from within tailscaled. By doing it this way, tailscaled can automatically
perform the migration as soon as the connection with the client frontend is
established.

Since tailscaled is already running as LocalSystem, it already has access to
the user's local AppData directory. The profile manager already knows which
user is connected, so we simply need to resolve the user's prefs file and read
it from there.

Of course, to properly migrate this information we need to also check system
policies. I moved a bunch of policy resolution code out of the GUI and into
a new package in util/winutil/policy.

ipn/ipnlocal: [serve] Trim mountPoint prefix from proxy path (#7334)
This change trims the mountPoint from the request URL path before
sending the request to the reverse proxy.

Today if you mount a proxy at `/foo` and request to
`/foo/bar/baz`, we leak the `mountPoint` `/foo` as part of the request
URL's path.

This fix makes removed the `mountPoint` prefix from the path so
proxied services receive requests as if they were running at the root
(`/`) path.

This could be an issue if the app generates URLs (in HTML or otherwise)
and assumes `/path`. In this case, those URLs will 404.

With that, I still think we should trim by default and not leak the
`mountPoint` (specific to Tailscale) into whatever app is hosted.
If it causes an issue with URL generation, I'd suggest looking at configuring
an app-specific path prefix or running Caddy as a more advanced
solution.

97b6d3e917 sockstats: remove per-interface stats from Get
They're not needed for the sockstats logger, and they're somewhat
expensive to return (since they involve the creation of a map per
label). We now have a separate GetInterfaces() method that returns
them instead (which we can still use in the PeerAPI debug endpoint).

If changing sockstatlog to sample at 10,000 Hz (instead of the default
of 10Hz), the CPU usage would go up to 59% on a iPhone XS. Removing the
per-interface stats drops it to 20% (a no-op implementation of Get that
returns a fixed value is 16%).

b797f773c7 ipn/ipnlocal: add support for funnel in tsnet
Previously the part that handled Funnel connections was not
aware of any listeners that tsnet.Servers might have had open
so it would check against the ServeConfig and fail.

Adding a ServeConfig for a TCP proxy was also not suitable in this
scenario as that would mean creating two different listeners and have
one forward to the other, which really meant that you could not have
funnel and tailnet-only listeners on the same port.

This also introduces the ipn.FunnelConn as a way for users to identify
whether the call is coming over funnel or not. Currently it only holds
the underlying conn and the target as presented in the "Tailscale-Ingress-Target"
header.

We can use the TCP_CONNECTION_INFO getsockopt() on Darwin to get

for UDP sockets (or on Linux/Android), we can't rely on it for actual

However, we can use it to validate the stats that we collect ourselves
using read/write hooks, so that we can be more confident in them. We
do need additional hooks from the Go standard library (added in
tailscale/go#59) to be able to collect them.

9cb332f0e2 sockstats: instrument networking code paths
Uses the hooks added by tailscale/go#45 to instrument the reads and
writes on the major code paths that do network I/O in the client. The
convention is to use "<package>.<type>:<label>" as the annotation for
the responsible code path.

Enabled on iOS, macOS and Android only, since mobile platforms are the
ones we're most interested in, and we are less sensitive to any
throughput degradation due to the per-I/O callback overhead (macOS is
also enabled for ease of testing during development).

For now just exposed as counters on a /v0/sockstats PeerAPI endpoint.

We also keep track of the current interface so that we can break out
the stats by interface.

Exposes the delegated interface data added by #7248 in the debug

it may be handy in the future as well.

Also makes the interfaces table slightly easier to parse by adding

fa932fefe7 net/interfaces: redo how we get the default interface on macOS and iOS
With #6566 we added an external mechanism for getting the default
interface, and used it on macOS and iOS (see tailscale/corp#8201).
The goal was to be able to get the default physical interface even when
using an exit node (in which case the routing table would say that the
Tailscale utun* interface is the default).

However, the external mechanism turns out to be unreliable in some
cases, e.g. when multiple cellular interfaces are present/toggled (I
have occasionally gotten my phone into a state where it reports the pdp_ip1
interface as the default, even though it can't actually route traffic).

It was observed that `ifconfig -v` on macOS reports an "effective interface"
for the Tailscale utn* interface, which seems promising. By examining
the ifconfig source code, it turns out that this is done via a
SIOCGIFDELEGATE ioctl syscall. Though this is a private API, it appears
to have been around for a long time (e.g. it's in the 10.13 xnu release
at https://opensource.apple.com/source/xnu/xnu-4570.41.2/bsd/net/if_types.h.auto.html)
and thus is unlikely to go away.

We can thus use this ioctl if the routing table says that a utun*
interface is the default, and go back to the simpler mechanism that
we had before #6566.

62f4df3257 net/interfaces, net/netns: add node attributes to control default interface getting and binding
With #6566 we started to more aggressively bind to the default interface
on Darwin. We are seeing some reports of the wrong cellular interface
being chosen on iOS. To help with the investigation, this adds to knobs
to control the behavior changes:
- CapabilityDebugDisableAlternateDefaultRouteInterface disables the
  alternate function that we use to get the default interface on macOS
  and iOS (implemented in tailscale/corp#8201). We still log what it
  would have returned so we can see if it gets things wrong.
- CapabilityDebugDisableBindConnToInterface is a bigger hammer that
  disables binding of connections to the default interface altogether.

We now handle the case where the NetworkMap.SelfNode has already expired
and do not return an expiry time in the past (which causes an ~infinite
loop of timers to fire).

Additionally, we now add an explicit check to ensure that the next
expiry time is never before the current local-to-the-system time, to
ensure that we don't end up in a similar situation due to clock skew.

Finally, we add more tests for this logic to ensure that we don't
regress on these edge cases.

4973956419 ipn/ipnlocal: add /reset-auth LocalAPI endpoint
The iOS has a command to reset the persisted state of the app, but it
was doing its own direct keychain manipulation. This proved to be
brittle (since we changed how preferences are stored with #6022), so
we instead add a LocalAPI endpoint to do do this, which can be updated
in tandem.

This clears the same state as the iOS implementation (tailscale/corp#3186),
that is the machine key and preferences (which includes the node key).
Notably this does not clear the logtail ID, so that logs from the device
still end up in the same place.

Tailscale interface, but macOS errors out if we try to
to listen on privileged ports binding only to a specific

We also implement the lc.Control hook, same as we do for

we do and would likely be required when Apple gets around to
fixing per-interface priviliged port binding.

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().

f1ab11e961 ipn/ipnlocal,tailcfg: introduce capability to gate TKA init paths
Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths. With
this change:

 - Enablement codepaths (NetworkLockInit) and initialization codepaths (tkaBootstrapFromGenesisLocked via tkaSyncIfNeeded)
   require either the WIP envknob or CapabilityTailnetLockAlpha.
 - Normal operation codepaths (tkaSyncIfNeeded, tkaFilterNetmapLocked) require TKA to be initialized, or either-or the
   envknob / capability.
 - Auxillary commands (ie: changing tka keys) require TKA to be initialized.

The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being
sent the capability or setting the envknob on tailscaled yourself.

I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock().

659e7837c6 health, ipn/ipnlocal: when -no-logs-no-support is enabled, deny access to tailnets that have network logging enabled
We want users to have the freedom to start tailscaled with `-no-logs-no-support`,
but that is obviously in direct conflict with tailnets that have network logging
enabled.

When we detect that condition, we record the issue in health, notify the client,
set WantRunning=false, and bail.

We clear the item in health when a profile switch occurs, since it is a
per-tailnet condition that should not propagate across profiles.

235309adc4 all: store NL keys per profile
This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct.
This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey.

It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional
to be able to delete the "/tka" dir if it exists.

This means that we will have a unique key per profile, and a unique directory per profile.

Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not
delete the ChonkDir.

3f8e185003 health: add Warnable, move ownership of warnable items to callers
The health package was turning into a rando dumping ground. Make a new
Warnable type instead that callers can request an instance of, and
then Set it locally in their code without the health package being
aware of all the things that are warnable. (For plenty of things the
health package will want to know details of how Tailscale works so it
can better prioritize/suppress errors, but lots of the warnings are
pretty leaf-y and unrelated)

This just moves two of the health warnings. Can probably move more
later.

8e85227059 cmd/tailscale/cli: [set] handle selectively modifying routes/exit node
Noticed this while debugging something else, we would reset all routes if
either `--advertise-exit-node` or `--advertise-routes` were set. This handles
correctly updating them.

Also added tests.

73b8968404 ipn/ipnlocal: ensure Persist information is saved to server mode start state
Numerous issues have been filed concerning an inability to install and run
Tailscale headlessly in unattended mode, particularly after rebooting. The
server mode `Prefs` stored in `server-state.conf` were not being updated with
`Persist` state once the node had been succesfully logged in.

Users have been working around this by finagling with the GUI to make it force
a state rewrite. This patch makes that unnecessary by ensuring the required
server mode state is updated when prefs are updated by the control client.

Fixes https://github.com/tailscale/tailscale/issues/3186
