Irbe Krumina	95dcc1745b	cmd/k8s-operator: reconcile tailscale Ingresses when their backend Services change. (#11255 ) This is so that if a backend Service gets created after the Ingress, it gets picked up by the operator.

Irbe Krumina	303125d96d	cmd/k8s-operator: configure all proxies with declarative config (#11238 ) Containerboot container created for operator's ingress and egress proxies are now always configured by passing a configfile to tailscaled (tailscaled --config <configfile-path>. It does not run 'tailscale set' or 'tailscale up'. Upgrading existing setups to this version as well as downgrading existing setups at this version works.

Anton Tolchanov	8cc5c51888	health: warn about reverse path filtering and exit nodes When reverse path filtering is in strict mode on Linux, using an exit node blocks all network connectivity. This change adds a warning about this to `tailscale status` and the logs. Example in `tailscale status`: ``` - not connected to home DERP region 22 - The following issues on your machine will likely make usage of exit nodes impossible: [interface "eth0" has strict reverse-path filtering enabled], please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310 ``` Example in the logs: ``` 2024/02/21 21:17:07 health("overall"): error: multiple errors: not in map poll The following issues on your machine will likely make usage of exit nodes impossible: [interface "eth0" has strict reverse-path filtering enabled], please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310 ``` Updates #3310 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	4 months ago
Nick Khyl	7ef1fb113d	cmd/tailscaled, ipn/ipnlocal, wgengine: shutdown tailscaled if wgdevice is closed Tailscaled becomes inoperative if the Tailscale Tunnel wintun adapter is abruptly removed. wireguard-go closes the device in case of a read error, but tailscaled keeps running. This adds detection of a closed WireGuard device, triggering a graceful shutdown of tailscaled. It is then restarted by the tailscaled watchdog service process.

Percy Wegmann	50fb8b9123	tailfs: replace webdavfs with reverse proxies Instead of modeling remote WebDAV servers as actual webdav.FS instances, we now just proxy traffic to them. This not only simplifies the code, but it also allows WebDAV locking to work correctly by making sure locks are handled by the servers that need to (i.e. the ones actually serving the files).

James Tucker	edbad6d274	cmd/derper: add user timeout and reduce TCP keepalive The derper sends an in-protocol keepalive every 60-65s, so frequent TCP keepalives are unnecessary. In this tuning TCP keepalives should never occur for a DERP client connection, as they will send an L7 keepalive often enough to always reset the TCP keepalive timer. If however a connection does not receive an ACK promptly it will now be shutdown, which happens sooner than it would with a normal TCP keepalive tuning. This re-tuning reduces the frequency of network traffic from derp to client, reducing battery cost.

Irbe Krumina	5bd19fd3e3	cmd/k8s-operator,k8s-operator: proxy configuration mechanism via a new ProxyClass custom resource (#11074 ) * cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource. ProxyClass custom resource can be used to specify customizations for the proxy resources created by the operator. Add a reconciler that validates ProxyClass resources and sets a Ready condition to True or False with a corresponding reason and message. This is required because some fields (labels and annotations) require complex validations that cannot be performed at custom resource apply time. Reconcilers that use the ProxyClass to configure proxy resources are expected to verify that the ProxyClass is Ready and not proceed with resource creation if configuration from a ProxyClass that is not yet Ready is required. If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet. If a tailscale Ingress has a tailscale.com/proxy-class annotation and the referenced ProxyClass custom resource is available and Ready, apply configuration from the ProxyClass to the proxy resources that will be created for the Ingress. Add a new .proxyClass field to the Connector spec. If connector.spec.proxyClass is set to a ProxyClass that is available and Ready, apply configuration from the ProxyClass to the proxy resources created for the Connector. Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml.

James Tucker	24bac27632	util/rands: add Shuffle and Perm functions with on-stack RNG state The new math/rand/v2 package includes an m-local global random number generator that can not be reseeded by the user, which is suitable for most uses without the RNG pools we have in a number of areas of the code base. The new API still does not have an allocation-free way of performing a seeded operations, due to the long term compiler bug around interface parameter escapes, and the Source interface. This change introduces the two APIs that math/rand/v2 can not yet replace efficiently: seeded Perm() and Shuffle() operations. This implementation chooses to use the PCG random source from math/rand/v2, as with sufficient compiler optimization, this source should boil down to only two on-stack registers for random state under ideal conditions.

Irbe Krumina	a6cc2fdc3e	cmd/{containerboot,k8s-operator/deploy/manifests}: optionally allow proxying cluster traffic to a cluster target via ingress proxy (#11036 ) * cmd/containerboot,cmd/k8s-operator/deploy/manifests: optionally forward cluster traffic via ingress proxy. If a tailscale Ingress has tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation, configure the associated ingress proxy to have its tailscale serve proxy to listen on Pod's IP address. This ensures that cluster traffic too can be forwarded via this proxy to the ingress backend(s). In containerboot, if EXPERIMENTAL_PROXY_CLUSTER_TRAFFIC_VIA_INGRESS is set to true and the node is Kubernetes operator ingress proxy configured via Ingress, make sure that traffic from within the cluster can be proxied to the ingress target.

Will Norris	13f8a669d5	cmd/gitops-pusher: fix logic for checking credentials gitops-pusher supports authenticating with an API key or OAuth credentials (added in #7393). You shouldn't ever use both of those together, so we error if both are set. In tailscale/gitops-acl-action#24, OAuth support is being added to the GitHub action. In that environment, both the TS_API_KEY and OAuth variables will be set, even if they are empty values. This causes an error in gitops-pusher which expects only one to be set.
