Irbe Krumina	90c4067010	util/linuxfw: add container-friendly IPv6 NAT check (#11353) ... Remove IPv6 NAT check when routing is being set up using nftables. This is unnecessary as support for nftables was added after support for IPv6. https://tldp.org/HOWTO/Linux+IPv6-HOWTO/ch18s04.html https://wiki.nftables.org/wiki-nftables/index.php/Building_and_installing_nftables_from_sources Additionally, run an extra check for IPv6 NAT support when the routing is set up with iptables. This is because the earlier checks rely on being able to use modprobe and on /proc/net/ip6_tables_names being populated on start - these conditions are usually not true in container environments.

Percy Wegmann	00373f07ac	ipn/ipnlocal: exclude mullvad exit nodes from TailFS peers list ... This is a temporary solution to at least omit Mullvad exit nodes from the list of TailFS peers. Once we can identify peers that are actually sharing via TailFS, we can remove this, but for alpha it'll be sufficient to just omit Mullvad.

Sonia Appasamy	c58c59ee54	{ipn,cmd/tailscale/cli}: move ServeConfig mutation logic to ipn/serve ... Moving logic that manipulates a ServeConfig into recievers on the ServeConfig in the ipn package. This is setup work to allow the web client and cli to both utilize these shared functions to edit the serve config. Any logic specific to flag parsing or validation is left untouched in the cli command. The web client will similarly manage its validation of user's requested changes. If validation logic becomes similar-enough, we can make a serve util for shared functionality, which likely does not make sense in ipn.

Percy Wegmann	232a2d627c	tailfs: only impersonate unprivileged user if able to sudo -u as that user ... When serving TailFS shares, tailscaled executes another tailscaled to act as a file server. It attempts to execute this child process as an unprivileged user using sudo -u. This is important to avoid accessing files as root, which would result in potential privilege escalation. Previously, tailscaled assumed that it was running as someone who can sudo -u, and would fail if it was unable to sudo -u. With this commit, if tailscaled is unable to sudo -u as the requested user, and tailscaled is not running as root, then tailscaled executes the the file server process under the same identity that ran tailscaled, since this is already an unprivileged identity. In the unlikely event that tailscaled is running as root but is unable to sudo -u, it will refuse to run the child file server process in order to avoid privilege escalation.

Percy Wegmann	2d5d6f5403	ipn,wgengine: only intercept TailFS traffic on quad 100 ... This fixes a regression introduced with 993acf4 and released in v1.60.0. The regression caused us to intercept all userspace traffic to port 8080 which prevented users from exposing their own services to their tailnet at port 8080. Now, we only intercept traffic to port 8080 if it's bound for 100.100.100.100 or fd7a:115c:a1e0::53.

It also removes HandshakeAttempts from PeerStatusLite that was just added as it wasn't needed yet and is now accessible ala cart as needed from the Peer type accessor. None of this is used yet.

This also requires adding newer versions of @typescript-eslint/eslint-plugin and @typescript-eslint/parser to our resolutions as eslint-config-react-app pulls in versions that otherwise do not support typescript 5.x. eslint-config-react-app has not been updated in 2 years and is seemingly abandoned, so we may wish to fork it or move to a different eslint config in the future.

Andrew Dunham	c5abbcd4b4	wgengine/netstack: add a per-client limit for in-flight TCP forwards ... This is a fun one. Right now, when a client is connecting through a subnet router, here's roughly what happens: 1. The client initiates a connection to an IP address behind a subnet router, and sends a TCP SYN 2. The subnet router gets the SYN packet from netstack, and after running through acceptTCP, starts DialContext-ing the destination IP, without accepting the connection¹ 3. The client retransmits the SYN packet a few times while the dial is in progress, until either... 4. The subnet router successfully establishes a connection to the destination IP and sends the SYN-ACK back to the client, or... 5. The subnet router times out and sends a RST to the client. 6. If the connection was successful, the client ACKs the SYN-ACK it received, and traffic starts flowing As a result, the notification code in forwardTCP never notices when a new connection attempt is aborted, and it will wait until either the connection is established, or until the OS-level connection timeout is reached and it aborts. To mitigate this, add a per-client limit on how many in-flight TCP forwarding connections can be in-progress; after this, clients will see a similar behaviour to the global limit, where new connection attempts are aborted instead of waiting. This prevents a single misbehaving client from blocking all other clients of a subnet router by ensuring that it doesn't starve the global limiter. Also, bump the global limit again to a higher value. ¹ We can't accept the connection before establishing a connection to the remote server since otherwise we'd be opening the connection and then immediately closing it, which breaks a bunch of stuff; see #5503 for more details.
