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.

Brad Fitzpatrick	8aa5c3534d	ipn/ipnlocal: simplify authURL vs authURLSticky, remove interact field ... The previous LocalBackend & CLI 'up' changes improved some stuff, but might've been too aggressive in some edge cases. This simplifies the authURL vs authURLSticky distinction and removes the interact field, which seemed to just just be about duplicate URL suppression in IPN bus, back from when the IPN bus was a single client at a time. This moves that suppression to a different spot.

Percy Wegmann	7209c4f91e	drive: parse depth 1 PROPFIND results to include children in cache ... Clients often perform a PROPFIND for the parent directory before performing PROPFIND for specific children within that directory.

By immediately adding that to the cache, we save a roundtrip to the remote peer on the PROPFIND for the specific child.

Irbe Krumina	d86d1e7601	cmd/k8s-operator,cmd/containerboot,ipn,k8s-operator: turn off stateful filter for egress proxies. (#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. Deprecate EXPERIMENTAL_TS_CONFIGFILE_PATH env var and introduce a new TS_EXPERIMENTAL_VERSIONED_CONFIG env var that can be used to provide containerboot a directory that should contain one or more tailscaled config files named cap-<tailscaled-cap-version>.hujson. Containerboot will pick the one with the newest capability version that is not newer than its current capability version. Proxies with this change will not work with older Tailscale Kubernetes operator versions - users must ensure that the deployed operator is at the same version or newer (up to 4 version skew) than the proxies.

Andrew Dunham	5708fc0639	wgengine/router: print Docker warning when stateful filtering is enabled ... When Docker is detected on the host and stateful filtering is enabled, Docker containers may be unable to reach Tailscale nodes (depending on the network settings of a container). Detect Docker when stateful filtering is enabled and print a health warning to aid users in noticing this issue. We avoid printing the warning if the current node isn't advertising any subnet routes and isn't an exit node, since without one of those being true, the node wouldn't have the correct AllowedIPs in WireGuard to allow a Docker container to connect to another Tailscale node anyway.

We are now publishing nameserver images to tailscale/k8s-nameserver, so we can start defaulting the images if users haven't set them explicitly, same as we already do with proxy images. The nameserver images are currently only published for unstable track, so we have to use the static 'unstable' tag. Once we start publishing to stable, we can make the operator default to its own tag (because then we'll know that for each operator tag X there is also a nameserver tag X as we always cut all images for a given tag.

Andrew Dunham	8f7f9ac17e	wgengine/netstack: handle 4via6 routes that are advertised by the same node ... Previously, a node that was advertising a 4via6 route wouldn't be able to make use of that same route; the packet would be delivered to Tailscale, but since we weren't accepting it in handleLocalPackets, the packet wouldn't be delivered to netstack and would never hit the 4via6 logic.

Brad Fitzpatrick	e968b0ecd7	cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more ... The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda chaotic and they both need to be redone/deleted (respectively), but this fixes some buggy behavior meanwhile. We were previously calling StartLoginInteractive (to start the controlclient's RegisterRequest) redundantly in some cases, causing test flakes depending on timing and up's weird state machine. We only need to call StartLoginInteractive in the client if Start itself doesn't. But Start doesn't tell us that. So cheat a bit and a put the information about whether there's a current NodeKey in the ipn.Status. It used to be accessible over LocalAPI via GetPrefs as a private key but we removed that for security. But a bool is fine. So then only call StartLoginInteractive if that bool is false and don't do it in the WatchIPNBus loop.
