Brad Fitzpatrick 9d801a42d7 Add secret Run Exit Node option when "debug" is searched for.
And bump tailscale dep, to bring in new ipn.Prefs API and wire up
ExitDNS for Android.

This change has no visible behavior change to anybody unless they
search for "debug" and then hit the "..." menu.

Denton Gentry 79bb2f33d0 ui: more robust isConnected check.
1. Follow
   https://developer.android.com/training/monitoring-device-state/connectivity-status-type
   to determine whether to report ourself as having connectivity or not.

   Tested by turning the Wifi & LTE off and on, seems to work well in
   the contrived test case.

2. Call superclass for onLost() and onLinkPropertiesChanged() handlers.
   Current Android versions have no code in the superclass of these two
   callbacks, but future proofiness.

3. Log when the UI report of LostInternet changes, so we can find it.

Merge branch 'main' into dns 3 years ago
Denton Gentry ca696b116c Update opensource repository 3 years ago
Denton Gentry 5c9cec0064 retrieve current DNS servers.
Add getDnsConfigAsString() to retrieve the current DNS
configuration from the Android platform. This implements
several mechanisms to retrieve DNS information, suitable
for different Android versions:

Android 7 and later use ConnectivityManager getAllNetworks(),
then iterate over each network to retrieve DNS servers and
search domains using the LinkProperties.

Android 6 and earlier can only retrieve the currently active
interface using ConnectivityManager getActiveNetwork(), but have
two additional fallback options which leverage the system
properties available in older Android releases.

--------

Also changed how LinkChange notification works, switching from
the older BroadcastReceiver of a ConnectivityManager Intent to
the newer ConnectivityManager.registerNetworkCallback. We need
this because the onAvailable event is too early, we get notified
that LTE is up before its DNS servers have been set. We need
to wait for the onLinkPropertiesChanged event instead, which is
only available with registerNetworkCallback.

Denton Gentry 02a6ae0e0d cmd/tailscale: implement getInterfaces + SDK 30
SDK 30 prohibits syscall.NetlinkRIB(syscall.RTM_GETADDR, ...)
which Go's net.Interfaces uses. Implement an Android
specific version of net.Interfaces to use instead.

Passing primitive types across JNI is relatively straightforward,
passing a single object of a complex class is annoying but still
possible, but passing lists and other more complex data structures is
way harder. As such, this commit added a Java routine to render the
interface information to a string and pass that across JNI as a
primitive type for Go code to parse.

Denton Gentry 7dedc91a80 ui: show IPv6 address if there's no IPv4 address
There are several situations where a peer may only have IPv6:
+ it was authorized using an ephemeral node key
  https://tailscale.com/kb/1111/ephemeral-nodes/
+ the Tailnet has IPv4 disabled
  https://twitter.com/bradfitz/status/1398380415124082690

So:
+ if a peer has an IPv4 address, display that.
+ if a peer does not have an IPv4 address, display IPv6.
+ If a peer does not have either IPv4 or IPv6 then leave
  the address blank. Not sure how this could happen.

Denton Gentry ec8133a972 backend: use dns.NewNoopManager.
Android updates its DNS config in updateTUN() when in response
to several different channels from the backend.

There is not an Android-specific NewOSConfigurator, we end
up pulling in the Linux NewOSConfigurator:
https://github.com/tailscale/tailscale/blob/main/net/dns/manager_linux.go

The Linux DNS manager expects to be able to write to /etc/resolv.conf,
which does not work on Android and causes errors in updating DNS config.

Instead, allocate dns.NewNoopManager to disable the DNS manager, and
rely on the updateTUN() code to handle DNS.

Elias Naur b151de039b cmd/tailscale: simplify non-blocking coalescing channels
Three variables are used everywhere a single non-blocking producer sends
values where only the latest is relevant:

    var (
	    mu sync.Mutex
	    latest T
	    notify = make(chan struct{}, 1)
    )

By draining the notification channel before sending through it, we
can simplify to just one channel:

    latest = make(chan T, 1)

Thanks to Chris Waldon for showing me this neat trick.

Elias Naur 9db851a113 cmd/tailscale: notify user when VPN access is denied
When tailscale starts, any other active VPN service is automatically closed by the system.
However, if the other VPN service is configured to be always-on, we will be denied access
to set up a VPN. The user may not realize this case, so this change adds a notification
when we're denied access.

The failure mode is identical to the user denying access tthrough the system dialog
shown first time Tailscale starts, so the notification also mentions that case.
