Andrew Dunham	7429e8912a	wgengine/netstack: fix bug with duplicate SYN packets in client limit ... This fixes a bug that was introduced in #11258 where the handling of the per-client limit didn't properly account for the fact that the gVisor TCP forwarder will return 'true' to indicate that it's handled a duplicate SYN packet, but not launch the handler goroutine. In such a case, we neither decremented our per-client limit in the wrapper function, nor did we do so in the handler function, leading to our per-client limit table slowly filling up without bound. Fix this by doing the same duplicate-tracking logic that the TCP forwarder does so we can detect such cases and appropriately decrement our in-flight counter.

James Tucker	055117ad45	util/linuxfw: fix support for containers without IPv6 iptables filters (#11381) ... There are container environments such as GitHub codespaces that have partial IPv6 support - routing support is enabled at the kernel level, but lacking IPv6 filter support in the iptables module. In the specific example of the codespaces environment, this also has pre-existing legacy iptables rules in the IPv4 tables, as such the nascent firewall mode detection will always pick iptables. We would previously fault trying to install rules to the filter table, this catches that condition earlier, and disables IPv6 support under these conditions.

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.

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.
