Brad Fitzpatrick	2409661a0d	control/controlclient: delete old naclbox code, require ts2021 Noise Updates #11585 Updates tailscale/corp#18882 Change-Id: I90e2e4a211c58d429e2b128604614dde18986442 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	8 months ago
James Tucker	9401b09028	control/controlclient: move client watchdog to cover initial request The initial control client request can get stuck in the event that a connection is established but then lost part way through, without any ICMP or RST. Ensure that the control client will be restarted by timing out that initial request as well. Fixes #11542 Signed-off-by: James Tucker <james@tailscale.com>	8 months ago
Brad Fitzpatrick	7b34154df2	all: deprecate Node.Capabilities (more), remove PeerChange.Capabilities [capver 89] First we had Capabilities []string. Then https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a superset of Capabilities. Except we never really finished the transition inside the codebase to go all-in on CapMap. This does so. Notably, this coverts Capabilities on the wire early to CapMap internally so the code can only deal in CapMap, even against an old control server. In the process, this removes PeerChange.Capabilities support, which no known control plane sent anyway. They can and should use PeerChange.CapMap instead.

Brad Fitzpatrick	b104688e04	ipn/ipnlocal, types/netmap: replace hasCapability with set lookup on NetworkMap When node attributes were super rare, the O(n) slice scans looking for node attributes was more acceptable. But now more code and more users are using increasingly more node attributes. Time to make it a map.

Brad Fitzpatrick	8444937c89	control/controlclient: fix panic regression from earlier load balancer hint header In the recent `20e9f3369` we made HealthChangeRequest machine requests include a NodeKey, as it was the oddball machine request that didn't include one. Unfortunately, that code was sometimes being called (at least in some of our integration tests) without a node key due to its registration with health.RegisterWatcher(direct.ReportHealthChange). Fortunately tests in corp caught this before we cut a release. It's possible this only affects this particular integration test's environment, but still worth fixing.

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491 ) Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

Brad Fitzpatrick	44c6909c92	control/controlclient: move watchdog out of mapSession In prep for making mapSession's lifetime not be 1:1 with a single HTTP response's lifetime, this moves the inactivity timer watchdog out of mapSession and into the caller that owns the streaming HTTP response. (This is admittedly closer to how it was prior to the mapSession type existing, but that was before we connected some dots which were impossible to even see before the mapSession type broke the code up.)

Brad Fitzpatrick	c87d58063a	control/controlclient: move lastPrintMap field from Direct to mapSession It was a really a mutable field owned by mapSession that we didn't move in earlier commits. Once moved, it's then possible to de-func-ify the code and turn it into a regular method rather than an installed optional hook.

Adrian Dewhurst	5347e6a292	control/controlclient: support certstore without cgo We no longer build Windows releases with cgo enabled, which automatically turned off certstore support.

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).

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.

Brad Fitzpatrick	42072683d6	control/controlknobs: move ForceBackgroundSTUN to controlknobs.Knobs This is both more efficient (because the knobs' bool is only updated whenever Node is changed, rarely) and also gets us one step closer to removing a case of storing a netmap.NetworkMap in magicsock.
