Irbe Krumina	a95ea31a4e	kube,tailcfg: store parsed recorder tags in a separate field (#12429 ) Add an additional RecorderAddrs field to tailscale.com/cap/kubernetes capability. RecorderAddrs will only be populated by control with the addresses of any tsrecorder tags set via Recorder. Updates tailscale/corp#19821 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	6 months ago
Irbe Krumina	c3e2b7347b	tailcfg,cmd/k8s-operator,kube: move Kubernetes cap to a location that can be shared with control (#12236 ) This PR is in prep of adding logic to control to be able to parse tailscale.com/cap/kubernetes grants in control: - moves the type definition of PeerCapabilityKubernetes cap to a location shared with control. - update the Kubernetes cap rule definition with fields for granting kubectl exec session recording capabilities. - adds a convenience function to produce tailcfg.RawMessage from an arbitrary cap rule and a test for it. An example grant defined via ACLs: "grants": [{ "src": ["tag:eng"], "dst": ["tag:k8s-operator"], "app": { "tailscale.com/cap/kubernetes": [{ "recorder": ["tag:my-recorder"] “enforceRecorder”: true }], }, } ] This grant enforces `kubectl exec` sessions from tailnet clients, matching `tag:eng` via API server proxy matching `tag:k8s-operator` to be recorded and recording to be sent to a tsrecorder instance, matching `tag:my-recorder`. The type needs to be shared with control because we want control to parse this cap and resolve tags to peer IPs.

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.

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).

Tom DNetto	c08cf2a9c6	all: declare & plumb IPv6 masquerade address for peer This PR plumbs through awareness of an IPv6 SNAT/masquerade address from the wire protocol through to the low-level (tstun / wgengine). This PR is the first in two PRs for implementing IPv6 NAT support to/from peers. A subsequent PR will implement the data-plane changes to implement IPv6 NAT - this is just plumbing.

Maisem Ali	19a9d9037f	tailcfg: add NodeCapMap Like PeerCapMap, add a field to `tailcfg.Node` which provides a map of Capability to raw JSON messages which are deferred to be parsed later by the application code which cares about the specific capabilities. This effectively allows us to prototype new behavior without having to commit to a schema in tailcfg, and it also opens up the possibilities to develop custom behavior in tsnet applications w/o having to plumb through application specific data in the MapResponse.

Maisem Ali	d06b48dd0a	tailcfg: add RawMessage This adds a new RawMessage type backed by string instead of the json.RawMessage which is backed by []byte.

Brad Fitzpatrick	ba5aa2c486	version, cmd/tailscale: add version.Meta, tailscale version --json Add `tailscale version --json` JSON output mode. This will be used later for a double-opt-in (per node consent like Tailscale SSH + control config) to let admins do remote upgrades via `tailscale update` via a c2n call, which would then need to verify the cmd/tailscale found on disk for running tailscale update corresponds to the running tailscaled, refusing if anything looks amiss. Plus JSON output modes are just nice to have, rather than parsing unstable/fragile/obscure text formats.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.
