wgengine/magicsock: implement probing of UDP path lifetime (#10844)

2024-01-23T17:37:32Z

This commit implements probing of UDP path lifetime on the tail end of an active direct connection. Probing configuration has two parts - Cliffs, which are various timeout cliffs of interest, and CycleCanStartEvery, which limits how often a probing cycle can start, per-endpoint. Initially a statically defined default configuration will be used. The default configuration has cliffs of 10s, 30s, and 60s, with a CycleCanStartEvery of 24h. Probing results are communicated via clientmetric counters. Probing is off by default, and can be enabled via control knob. Probing is purely informational and does not yet drive any magicsock behaviors. Updates #540 Signed-off-by: Jordan Whited

control/controlknobs,wgengine/magicsock: implement SilentDisco toggle (#10195)

2023-11-13T18:05:04Z

This change exposes SilentDisco as a control knob, and plumbs it down to magicsock.endpoint. No changes are being made to magicsock.endpoint disco behavior, yet. Updates #540 Signed-off-by: Jordan Whited Co-authored-by: Brad Fitzpatrick

net/dns: retry forwarder requests over TCP

2023-09-25T20:42:07Z

We weren't correctly retrying truncated requests to an upstream DNS server with TCP. Instead, we'd return a truncated request to the user, even if the user was querying us over TCP and thus able to handle a large response. Also, add an envknob and controlknob to allow users/us to disable this behaviour if it turns out to be buggy (✨ DNS ✨).

control,tailcfg,wgengine/magicsock: add nodeAttr to enable/disable peer MTU

tailcfg: add NodeCapMap

2023-09-18T19:00:34Z

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.
