Andrea Gottardo	dd77111462	xcode/iOS: set MatchDomains when no route requires a custom DNS resolver (#10576 ) Updates https://github.com/tailscale/corp/issues/15802. On iOS exclusively, this PR adds logic to use a split DNS configuration in more cases, with the goal of improving battery life. Acting as the global DNS resolver on iOS should be avoided, as it leads to frequent wakes of IPNExtension. We try to determine if we can have Tailscale only handle DNS queries for resources inside the tailnet, that is, all routes in the DNS configuration do not require a custom resolver (this is the case for app connectors, for instance). If so, we set all Routes as MatchDomains. This enables a split DNS configuration which will help preserve battery life. Effectively, for the average Tailscale user who only relies on MagicDNS to resolve *.ts.net domains, this means that Tailscale DNS will only be used for those domains. This PR doesn't affect users with Override Local DNS enabled. For these users, there should be no difference and Tailscale will continue acting as a global DNS resolver.

James Tucker	538c2e8f7c	tool/gocross: add debug data to CGO builds We don't build a lot of tools with CGO, but we do build some, and it's extremely valuable for production services in particular to have symbols included - for perf and so on. I tested various other builds that could be affected negatively, in particular macOS/iOS, but those use split-dwarf already as part of their build path, and Android which does not currently use gocross. One binary which is normally 120mb only grew to 123mb, so the trade-off is definitely worthwhile in context.

James Tucker	9351eec3e1	net/netcheck: remove hairpin probes Palo Alto reported interpreting hairpin probes as LAND attacks, and the firewalls may be responding to this by shutting down otherwise in use NAT sessions prematurely. We don't currently make use of the outcome of the hairpin probes, and they contribute to other user confusion with e.g. the AirPort Extreme hairpin session workaround. We decided in response to remove the whole probe feature as a result.

Andrew Lytvynov	c9179bc261	various: disable stateful filtering by default (#12197 ) After some analysis, stateful filtering is only necessary in tailnets that use `autogroup:danger-all` in `src` in ACLs. And in those cases users explicitly specify that hosts outside of the tailnet should be able to reach their nodes. To fix local DNS breakage in containers, we disable stateful filtering by default.

Brad Fitzpatrick	964282d34f	ipn,wgengine: remove vestigial Prefs.AllowSingleHosts It was requested by the first customer 4-5 years ago and only used for a brief moment of time. We later added netmap visibility trimming which removes the need for this. It's been hidden by the CLI for quite some time and never documented anywhere else. This keeps the CLI flag, though, out of caution. It just returns an error if it's set to anything but true (its default).

James Tucker	8d1249550a	net/netcheck,wgengine/magicsock: add potential workaround for Palo Alto DIPP misbehavior Palo Alto firewalls have a typically hard NAT, but also have a mode called Persistent DIPP that is supposed to provide consistent port mapping suitable for STUN resolution of public ports. Persistent DIPP works initially on most Palo Alto firewalls, but some models/software versions have a bug which this works around. The bug symptom presents as follows: - STUN sessions resolve a consistent public IP:port to start with - Much later netchecks report the same IP:Port for a subset of sessions, most often the users active DERP, and/or the port related to sustained traffic. - The broader set of DERPs in a full netcheck will now consistently observe a new IP:Port. - After this point of observation, new inbound connections will only succeed to the new IP:Port observed, and existing/old sessions will only work to the old binding. In this patch we now advertise the lowest latency global endpoint discovered as we always have, but in addition any global endpoints that are observed more than once in a single netcheck report. This should provide viable endpoints for potential connection establishment across a NAT with this behavior.

Andrea Gottardo	e5f67f90a2	xcode: allow ICMP ping relay on macOS + iOS platforms (#12048 ) Fixes tailscale/tailscale#10393 Fixes tailscale/corp#15412 Fixes tailscale/corp#19808 On Apple platforms, exit nodes and subnet routers have been unable to relay pings from Tailscale devices to non-Tailscale devices due to sandbox restrictions imposed on our network extensions by Apple. The sandbox prevented the code in netstack.go from spawning the `ping` process which we were using. Replace that exec call with logic to send an ICMP echo request directly, which appears to work in userspace, and not trigger a sandbox violation in the syslog.

Maisem Ali	1f51bb6891	net/tstun: do SNAT after filterPacketOutboundToWireGuard In a configuration where the local node (ip1) has a different IP (ip2) that it uses to communicate with a peer (ip3) we would do UDP flow tracking on the `ip2->ip3` tuple. When we receive the response from the peer `ip3->ip2` we would dnat it back to `ip3->ip1` which would then not match the flow track state and the packet would get dropped. To fix this, we should do flow tracking on the `ip1->ip3` tuple instead of `ip2->ip3` which requires doing SNAT after the running filterPacketOutboundToWireGuard.

(#12075 ) Turn off stateful filtering for egress proxies to allow cluster traffic to be forwarded to tailnet. Allow configuring stateful filter via tailscaled config file.

Containerboot will pick the one with the newest capability version that is not newer than its current capability version.
