Claire Wang	e070af7414	ipnlocal, magicsock: add more description to storing last suggested exit (#11998 ) node related functions Updates tailscale/corp#19681 Signed-off-by: Claire Wang <claire@tailscale.com>	7 months ago
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.

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. Let's add that support so that usage of 4via6 is consistent regardless of where the connection is initiated from.

Maisem Ali	af97e7a793	tailcfg,all: add/plumb Node.IsJailed This adds a new bool that can be sent down from control to do jailing on the client side. Previously this would only be done from control by modifying the packet filter we sent down to clients. This would result in a lot of additional work/CPU on control, we could instead just do this on the client. This has always been a TODO which we keep putting off, might as well do it now.

Brad Fitzpatrick	723c775dbb	tsd, ipnlocal, etc: add tsd.System.HealthTracker, start some plumbing This adds a health.Tracker to tsd.System, accessible via a new tsd.System.HealthTracker method. In the future, that new method will return a tsd.System-specific HealthTracker, so multiple tsnet.Servers in the same process are isolated. For now, though, it just always returns the temporary health.Global value. That permits incremental plumbing over a number of changes. When the second to last health.Global reference is gone, then the tsd.System.HealthTracker implementation can return a private Tracker. The primary plumbing this does is adding it to LocalBackend and its dozen and change health calls. A few misc other callers are also plumbed. Subsequent changes will flesh out other parts of the tree (magicsock, controlclient, etc).

Irbe Krumina	3af0f526b8	cmd{containerboot,k8s-operator},util/linuxfw: support ExternalName Services (#11802 ) * cmd/containerboot,util/linuxfw: support proxy backends specified by DNS name Adds support for optionally configuring containerboot to proxy traffic to backends configured by passing TS_EXPERIMENTAL_DEST_DNS_NAME env var to containerboot. Containerboot will periodically (every 10 minutes) attempt to resolve the DNS name and ensure that all traffic sent to the node's tailnet IP gets forwarded to the resolved backend IP addresses. Currently: - if the firewall mode is iptables, traffic will be load balanced accross the backend IP addresses using round robin. There are no health checks for whether the IPs are reachable. - if the firewall mode is nftables traffic will only be forwarded to the first IP address in the list. This is to be improved. * cmd/k8s-operator: support ExternalName Services Adds support for exposing endpoints, accessible from within a cluster to the tailnet via DNS names using ExternalName Services. This can be done by annotating the ExternalName Service with tailscale.com/expose: "true" annotation. The operator will deploy a proxy configured to route tailnet traffic to the backend IPs that service.spec.externalName resolves to. The backend IPs must be reachable from the operator's namespace.

Nick Khyl	9e1c86901b	wgengine\router: fix the Tailscale-In firewall rule to work on domain networks The Network Location Awareness service identifies networks authenticated against an Active Directory domain and categorizes them as "Domain Authenticated". This includes the Tailscale network if a Domain Controller is reachable through it. If a network is categories as NLM_NETWORK_CATEGORY_DOMAIN_AUTHENTICATED, it is not possible to override its category, and we shouldn't attempt to do so. Additionally, our Windows Firewall rules should be compatible with both private and domain networks. This fixes both issues. Fixes #11813 Signed-off-by: Nick Khyl <nickk@tailscale.com>	7 months ago

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.

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. Fixes #11283 Signed-off-by: Percy Wegmann <percy@tailscale.com> (cherry picked from commit `17cd0626f3`)	9 months ago
