Mihai Parparita bdc45b9066 wgengine/magicsock: fix panic when rebinding fails
We would replace the existing real implementation of nettype.PacketConn
with a blockForeverConn, but that violates the contract of atomic.Value
(where the type cannot change). Fix by switching to a pointer value
(atomic.Pointer[nettype.PacketConn]).

A longstanding issue, but became more prevalent when we started binding
connections to interfaces on macOS and iOS (#6566), which could lead to
the bind call failing if the interface was no longer available.

Fixes #6641

tsnet: add HTTP client method to tsnet.Server (#6669)
This allows tsnet services to make requests to other services in the
tailnet with the tsnet service identity instead of the identity of the
host machine. This also enables tsnet services to make requests to other
tailnet services without having to have the host machine join the
tailnet.

cmd/tailscale/cli, ipn/localapi: add funnel status to status command (#6402)
Fixes #6400

open up GETs for localapi serve-config to allow read-only access to
ServeConfig

`tailscale status` will include "Funnel on" status when Funnel is
configured. Prints nothing if Funnel is not running.

Example:

 $ tailscale status
 <nodes redacted>

 # Funnel on:
 #     - https://node-name.corp.ts.net
 #     - https://node-name.corp.ts.net:8443
 #     - tcp://node-name.corp.ts.net:10000

David Anderson 1b65630e83 cmd/containerboot: switch to IPN bus monitoring instead of polling.
We still have to shell out to `tailscale up` because the container image's
API includes "arbitrary flags to tailscale up", unfortunately. But this
should still speed up startup a little, and also enables k8s-bound containers
to update their device information as new netmap updates come in.

Fixes #6657

Aaron Klotz 98f21354c6 cmd/tailscaled: add a special command to tailscaled's Windows service for removing WinTun
WinTun is installed lazily by tailscaled while it is running as LocalSystem.
Based upon what we're seeing in bug reports and support requests, removing
WinTun as a lesser user may fail under certain Windows versions, even when that
user is an Administrator.

By adding a user-defined command code to tailscaled, we can ask the service to
do the removal on our behalf while it is still running as LocalSystem.

* The uninstall code is basically the same as it is in corp;
* The command code will be sent as a service control request and is protected by
  the SERVICE_USER_DEFINED_CONTROL access right, which requires Administrator.

I'll be adding follow-up patches in corp to engage this functionality.

Mihai Parparita 79f3a5d753 net/netns, net/interfaces: explicitly bind sockets to the default interface on all Darwin variants
We were previously only doing this for tailscaled-on-Darwin, but it also
appears to help on iOS. Otherwise, when we rebind magicsock UDP
connections after a cellular -> WiFi interface change they still keep
using cellular one.

To do this correctly when using exit nodes, we need to exclude the
Tailscale interface when getting the default route, otherwise packets
cannot leave the tunnel. There are native macOS/iOS APIs that we can
use to do this, so we allow those clients to override the implementation
of DefaultRouteInterfaceIndex.

Updates #6565, may also help with #5156

renamed from `useNetstack` to `onlyNetstack` which is 1 letter more but
more descriptive because we always have netstack enabled and `useNetstack`
doesn't convey what it is supposed to be used for. e.g. we always use

Tom DNetto 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().
