cmd/containerboot: add EXPERIMENTAL_TS_CONFIGFILE_PATH env var to allow passing tailscaled config in a file (#10759)
* cmd/containerboot: optionally configure tailscaled with a configfile.

If EXPERIMENTAL_TS_CONFIGFILE_PATH env var is set,
only run tailscaled with the provided config file.
Do not run 'tailscale up' or 'tailscale set'.

* cmd/containerboot: store containerboot accept_dns val in bool pointer

So that we can distinguish between the value being set to
false explicitly bs being unset.

Andrew Lytvynov 29e98e18f8
ssh/tailssh: use a local error instead of gossh.ErrDenied (#10743)
ErrDenied was added in [our fork of
x/crypto/ssh](acc6f8fe8d)
to short-circuit auth attempts once one fails.

In the case of our callbacks, this error is returned when SSH policy
check determines that a connection should not be allowed. Both
`NoClientAuthCallback` and `PublicKeyHandler` check the policy and will
fail anyway. The `fakePasswordHandler` returns true only if
`NoClientAuthCallback` succeeds the policy check, so it checks it
indirectly too.

The difference here is that a client might attempt all 2-3 auth methods
instead of just `none` but will fail to authenticate regardless.

net/interfaces: handle iOS network transitions (#10680)
Updates #8022
Updates #6075

On iOS, we currently rely on delegated interface information to figure out the default route interface.  The NetworkExtension framework in iOS seems to set the delegate interface only once, upon the *creation* of the VPN tunnel. If a network transition (e.g. from Wi-Fi to Cellular) happens while the tunnel is connected, it will be ignored and we will still try to set Wi-Fi as the default route because the delegated interface is not getting updated as connectivity transitions.

Here we work around this on the Swift side with a NWPathMonitor instance that observes the interface name of the first currently satisfied network path. Our Swift code will call into `UpdateLastKnownDefaultRouteInterface`, so we can rely on that when it is set.

If for any reason the Swift machinery didn't work and we don't get any updates, here we also have some fallback logic: we try finding a hardcoded Wi-Fi interface called en0. If en0 is down, we fall back to cellular (pdp_ip0) as a last resort. This doesn't handle all edge cases like USB-Ethernet adapters or multiple Ethernet interfaces, but it is good enough to ensure connectivity isn't broken.

I tested this on iPhones and iPads running iOS 17.1 and it appears to work. Switching between different cellular plans on a dual SIM configuration also works (the interface name remains pdp_ip0).

Adrian Dewhurst 3d57c885bf logpolicy: use syspolicy to override LogTarget
Previously, for Windows clients only, a registry value named LogTarget
could override the log server, but only if the environment variable was
unset.

To allow administrators to enforce using a particular log server, switch
this to make the registry value take precedence over the environment
variable, and switch to the newer syspolicy.GetString so that the log
target can be specified by a GPO more easily.

Nick Khyl c9836b454d net/netmon: fix goroutine leak in winMon if the monitor is never started
When the portable Monitor creates a winMon via newOSMon, we register
address and route change callbacks with Windows. Once a callback is hit,
it starts a goroutine that attempts to send the event into messagec and returns.
The newly started goroutine then blocks until it can send to the channel.
However, if the monitor is never started and winMon.Receive is never called,
the goroutines remain indefinitely blocked, leading to goroutine leaks and
significant memory consumption in the tailscaled service process on Windows.
Unlike the tailscaled subprocess, the service process creates but never starts
a Monitor.

This PR adds a check within the callbacks to confirm the monitor's active status,
and exits immediately if the monitor hasn't started.

Andrew Dunham 01286af82b net/interfaces: better handle multiple interfaces in LikelyHomeRouterIP
Currently, we get the "likely home router" gateway IP and then iterate
through all IPs for all interfaces trying to match IPs to determine the
source IP. However, on many platforms we know what interface the gateway
is through, and thus we don't need to iterate through all interfaces
checking IPs. Instead, use the IP address of the associated interface.

This better handles the case where we have multiple interfaces on a
system all connected to the same gateway, and where the first interface
that we visit (as iterated by ForeachInterfaceAddress) isn't also the
default internet route.

Sonia Appasamy c6a274611e client/web: use Tailscale IP known by peer node
Throughout the web UI, we present the tailscale addresses for the
self node. In the case of the node being shared out with a user
from another tailnet, the peer viewer may actually know the node
by a different IP than the node knows itself as (Tailscale IPs
can be configured as desired on a tailnet level). This change
includes two fixes:

1. Present the self node's addresses in the frontend as the addresses
   the viewing node knows it as (i.e. the addresses the viewing node
   uses to access the web client).

2. We currently redirect the viewer to the Tailscale IPv4 address if
   viewing it by MagicDNS name, or any other name that maps to the
   Tailscale node. When doing this redirect, which is primarily added
   for DNS rebinding protection, we now check the address the peer
   knows this node as, and redirect to specifically that IP.

wgengine/magicsock: fix handling of derp.PeerGoneMessage (#10589)
The switch in Conn.runDerpReader() on the derp.ReceivedMessage type
contained cases other than derp.ReceivedPacket that fell through to
writing to c.derpRecvCh, which should only be reached for
derp.ReceivedPacket. This can result in the last/previous
derp.ReceivedPacket to be re-handled, effectively creating a duplicate
packet. If the last derp.ReceivedPacket happens to be a
disco.CallMeMaybe it may result in a disco ping scan towards the
originating peer on the endpoints contained.

The change in this commit moves the channel write on c.derpRecvCh and
subsequent select awaiting the result into the derp.ReceivedMessage
case, preventing it from being reached from any other case. Explicit
continue statements are also added to non-derp.ReceivedPacket cases
where they were missing, in order to signal intent to the reader.
