Joe Tsai	c299a96624	all: apply consistent imports of "json" packages ... This runs: go run ./cmd/jsonimports -update -ignore=tempfork/ which applies the following rules: * Until the Go standard library formally accepts "encoding/json/v2" and "encoding/json/jsontext" into the standard library (i.e., they are no longer considered experimental), we forbid any code from directly importing those packages. Go code should instead import "github.com/go-json-experiment/json" and "github.com/go-json-experiment/json/jsontext". The latter packages contain aliases to the standard library if built on Go 1.25 with the goexperiment.jsonv2 tag specified. * Imports of "encoding/json" or "github.com/go-json-experiment/json/v1" must be explicitly imported under the package name "jsonv1". If both packages need to be imported, then the former should be imported under the package name "jsonv1std". * Imports of "github.com/go-json-experiment/json" must be explicitly imported under the package name "jsonv2". The latter two rules exist to provide clarity when reading code. Without them, it is unclear whether "json.Marshal" refers to v1 or v2. With them, however, it is clear that "jsonv1.Marshal" is calling v1 and that "jsonv2.Marshal" is calling v2.

Fran Bull	b48d2de6ab	cmd/natc,tsconsensus: add cluster config admin ... Add the ability for operators of natc in consensus mode to remove servers from the raft cluster config, without losing other state. Updates #14667 Signed-off-by: Fran Bull <fran@tailscale.com>	4 months ago
Fran Bull	d986baa18f	tsconsensus,cmd/natc: add 'follower only' bootstrap option ... Currently consensus has a bootstrap routine where a tsnet node tries to join each other node with the cluster tag, and if it is not able to join any other node it starts its own cluster. That algorithm is racy, and can result in split brain (more than one leader/cluster) if all the nodes for a cluster are started at the same time. Add a FollowOnly argument to the bootstrap function. If provided this tsnet node will never lead, it will try (and retry with exponential back off) to follow any node it can contact. Add a --follow-only flag to cmd/natc that uses this new tsconsensus functionality. Also slightly reorganize some arguments into opts structs.

Fran Bull	3b25e94352	cmd/natc: allow specifying the tsnet state dir ... Which can make operating the service more convenient. It makes sense to put the cluster state with this if specified, so rearrange the logic to handle that. Updates #14667 Signed-off-by: Fran Bull <fran@tailscale.com>	6 months ago
Fran Bull	3e08eab21e	cmd/natc: use new on disk state store for consensus ... Fixes #16027 Signed-off-by: Fran Bull <fran@tailscale.com>	6 months ago
Fran Bull	486a55f0a9	cmd/natc: add optional consensus backend ... Enable nat connector to be run on a cluster of machines for high availability. Updates #14667 Signed-off-by: Fran Bull <fran@tailscale.com>	6 months ago
Fran Bull	4cb9d5c183	cmd/natc: cleanup unused state ... perPeerState no longer needs to know the v6ULA. Updates #14667 Signed-off-by: Fran Bull <fran@tailscale.com>	8 months ago
Fran Bull	1e290867bd	cmd/natc: only store v4 addresses ... Because we derive v6 addresses from v4 addresses we only need to store the v4 address, not both. Updates #14667 Signed-off-by: Fran Bull <fran@tailscale.com>	8 months ago
Fran Bull	603a1d3830	cmd/natc: move address storage behind an interface ... Adds IPPool and moves all IP address management concerns behind that. Updates #14667 Signed-off-by: Fran Bull <fran@tailscale.com>	8 months ago
