Brad Fitzpatrick 8012bb4216 derp: refactor DERP server's peer-gone watch mechanism
In prep for upcoming flow tracking & mutex contention optimization
changes, this change refactors (subjectively simplifying) how the DERP
Server accounts for which peers have written to which other peers, to
be able to send PeerGoneReasonDisconnected messages to writes to
uncache their DRPO (DERP Return Path Optimization) routes.

Notably, this removes the Server.sentTo field which was guarded by
Server.mu and checked on all packet sends. Instead, the accounting is
moved to each sclient's sendLoop goroutine and now only needs to
acquire Server.mu for newly seen senders, the first time a peer sends
a packet to that sclient.

This change reduces the number of reasons to acquire Server.mu
per-packet from two to one. Removing the last one is the subject of an
upcoming change.

Andrew Dunham f572286bf9 gokrazy, various: use point versions of Go and update Nix deps
This un-breaks vim-go (which doesn't understand "go 1.23") and allows
the natlab tests to work in a Nix shell (by adding the "qemu-img" and
"mkfs.ext4" binaries to the shell). These binaries are available even on
macOS, as I'm testing on my M1 Max.

Brad Fitzpatrick 910462a8e0 derp: unify server's clientSet interface into concrete type
73280595a8 for #2751 added a "clientSet" interface to
distinguish the two cases of a client being singly connected (the
common case) vs tolerating multiple connections from the client at
once. At the time (three years ago) it was kinda an experiment
and we didn't know whether it'd stop the reconnect floods we saw
from certain clients. It did.

So this promotes it to a be first-class thing a bit, removing the
interface. The old tests from 73280595a were invaluable in ensuring
correctness while writing this change (they failed a bunch).

But the real motivation for this change is that it'll permit a future
optimization to add flow tracking for stats & performance where we
don't contend on Server.mu for each packet sent via DERP. Instead,
each client can track its active flows and hold on to a *clientSet and
ask the clientSet per packet what the active client is via one atomic
load rather than a mutex. And if the atomic load returns nil, we'll
know we need to ask the server to see if they died and reconnected and
got a new clientSet. But that's all coming later.

Maisem Ali 4d6a8224d5 util/linuxfw: fall back to nftables when iptables not found
When the desired netfilter mode was unset, we would always try
to use the `iptables` binary. In such cases if iptables was not found,
tailscaled would just crash as seen in #13440. To work around this, in those
cases check if the `iptables` binary even exists and if it doesn't fall back
to the nftables implementation.

Verified that it works on stock Ubuntu 24.04.

Nick Khyl 4dfde7bffc net/dns: disable DNS registration for Tailscale interface on Windows
We already disable dynamic updates by setting DisableDynamicUpdate to 1 for the Tailscale interface.
However, this does not prevent non-dynamic DNS registration from happening when `ipconfig /registerdns`
runs and in similar scenarios. Notably, dns/windowsManager.SetDNS runs `ipconfig /registerdns`,
triggering DNS registration for all interfaces that do not explicitly disable it.

In this PR, we update dns/windowsManager.disableDynamicUpdates to also set RegistrationEnabled to 0.

Anton Tolchanov fd6686d81a tka: truncate long rotation signature chains
When a rotation signature chain reaches a certain size, remove the
oldest rotation signature from the chain before wrapping it in a new
rotation signature.

Since all previous rotation signatures are signed by the same wrapping
pubkey (node's own tailnet lock key), the node can re-construct the
chain, re-signing previous rotation signatures. This will satisfy the
existing certificate validation logic.

cli: implement `tailscale dns status` (#13353)
Updates tailscale/tailscale#13326

This PR begins implementing a `tailscale dns` command group in the Tailscale CLI. It provides an initial implementation of `tailscale dns status` which dumps the state of the internal DNS forwarder.

Two new endpoints were added in LocalAPI to support the CLI functionality:

- `/netmap`: dumps a copy of the last received network map (because the CLI shouldn't have to listen to the ipn bus for a copy)
- `/dns-osconfig`: dumps the OS DNS configuration (this will be very handy for the UI clients as well, as they currently do not display this information)

My plan is to implement other subcommands mentioned in tailscale/tailscale#13326, such as `query`, in later PRs.

Nick Khyl 5bc9fafab8 ipn/ipnlocal: always send auth URL notifications when a user requests interactive login
This PR changes how LocalBackend handles interactive (initiated via StartLoginInteractive) and non-interactive (e.g., due to key expiration) logins,
and when it sends the authURL to the connected clients.

Specifically,
 - When a user initiates an interactive login by clicking Log In in the GUI, the LocalAPI calls StartLoginInteractive.
   If an authURL is available and hasn't expired, we immediately send it to all connected clients, suggesting them to open that URL in a browser.
   Otherwise, we send a login request to the control plane and set a flag indicating that an interactive login is in progress.
 - When LocalBackend receives an authURL from the control plane, we check if it differs from the previous one and whether an interactive login
   is in progress. If either condition is true, we notify all connected clients with the new authURL and reset the interactive login flag.

We reset the auth URL and flags upon a successful authentication, when a different user logs in and when switching Tailscale login profiles.

Finally, we remove the redundant dedup logic added to WatchNotifications in #12096 and revert the tests to their original state to ensure that
calling StartLoginInteractive always produces BrowseToURL notifications, either immediately or when the authURL is received from the control plane.
