Tom Proctor	d8a3683fdf	cmd/k8s-operator: restart ProxyGroup pods less (#14045) ... We currently annotate pods with a hash of the tailscaled config so that we can trigger pod restarts whenever it changes. However, the hash updates more frequently than is necessary causing more restarts than is necessary. This commit removes two causes; scaling up/down and removing the auth key after pods have initially authed to control. However, note that pods will still restart on scale-up/down because of the updated set of volumes mounted into each pod. Hopefully we can fix that in a planned follow-up PR.

Brad Fitzpatrick	c3306bfd15	control/controlhttp/controlhttpserver: split out Accept to its own package ... Otherwise all the clients only using control/controlhttp for the ts2021 HTTP client were also pulling in WebSocket libraries, as the server side always needs to speak websockets, but only GOOS=js clients speak it. This doesn't yet totally remove the websocket dependency on Linux because Linux has a envknob opt-in to act like GOOS=js for manual testing and force the use of WebSockets for DERP only (not control). We can put that behind a build tag in a future change to eliminate the dep on all GOOSes.

Irbe Krumina	2c8859c2e7	client/tailscale,ipn/{ipnlocal,localapi}: add a pre-shutdown localAPI endpoint that terminates control connections. (#14028) ... Adds a /disconnect-control local API endpoint that just shuts down control client. This can be run before shutting down an HA subnet router/app connector replica - it will ensure that all connection to control are dropped and control thus considers this node inactive and tells peers to switch over to another replica. Meanwhile the existing connections keep working (assuming that the replica is given some graceful shutdown period).

To allow more flexibility with CSPs, add a fully customizable `CSP` type that can be provided in `Config` and encodes itself into the correct format.

James Tucker	e1e22785b4	net/netcheck: ensure prior preferred DERP is always in netchecks ... In an environment with unstable latency, such as upstream bufferbloat, there are cases where a full netcheck could drop the prior preferred DERP (likely home DERP) from future netcheck probe plans. This will then likely result in a home DERP having a missing sample on the next incremental netcheck, ultimately resulting in a home DERP move. This change does not fix our overall response to highly unstable latency, but it is an incremental improvement to prevent single spurious samples during a full netcheck from alone triggering a flapping condition, as now the prior changes to include historical latency will still provide the desired resistance, and the home DERP should not move unless latency is consistently worse over a 5 minute period. Note that there is a nomenclature and semantics issue remaining in the difference between a report preferred DERP and a home DERP. A report preferred DERP is aspirational, it is what will be picked as a home DERP if a home DERP connection needs to be established. A nodes home DERP may be different than a recent preferred DERP, in which case a lot of netcheck logic is fallible. In future enhancements much of the DERP move logic should move to consider the home DERP, rather than recent report preferred DERP.

Nick Khyl	2336c340c4	util/syspolicy: implement a syspolicy store that reads settings from environment variables ... In this PR, we implement (but do not use yet, pending #13727 review) a syspolicy/source.Store that reads policy settings from environment variables. It converts a CamelCase setting.Key, such as AuthKey or ExitNodeID, to a SCREAMING_SNAKE_CASE, TS_-prefixed environment variable name, such as TS_AUTH_KEY and TS_EXIT_NODE_ID. It then looks up the variable and attempts to parse it according to the expected value type. If the environment variable is not set, the policy setting is considered not configured in this store (the syspolicy package will still read it from other sources). Similarly, if the environment variable has an invalid value for the setting type, it won't be used (though the reported/logged error will differ).
