Anton Tolchanov	8546ff98fb	tsweb: move varz handler(s) into separate modules ... This splits Prometheus metric handlers exposed by tsweb into two modules: - `varz.Handler` exposes Prometheus metrics generated by our expvar converter; - `promvarz.Handler` combines our expvar-converted metrics and native Prometheus metrics. By default, tsweb will use the promvarz handler, however users can keep using only the expvar converter. Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.

Anton Tolchanov	c153e6ae2f	prober: migrate to Prometheus metric library ... This provides an example of using native Prometheus metrics with tsweb. Prober library seems to be the only user of PrometheusVar, so I am removing support for it in tsweb.

Anton Tolchanov	11e6247d2a	tsweb: expose native Prometheus metrics in /debug/varz ... The handler will expose built-in process and Go metrics by default, which currently duplicate some of the expvar-proxied metrics (`goroutines` vs `go_goroutines`, `memstats` vs `go_memstats`), but as long as their names are different, Prometheus server will just scrape both. This will change /debug/varz behaviour for most tsweb binaries, but notably not for control, which configures a `tsweb.VarzHandler` [explicitly](a5b5d5167f/cmd/tailcontrol/tailcontrol.go (L779)) Updates https://github.com/tailscale/corp/issues/10205 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	1 year ago

Charlotte Brandhorst-Satzkorn	c573bef0aa	tailcfg,wgengine: add initial support for WireGuard only peers ... A peer can have IsWireGuardOnly, which means it will not support DERP or Disco, and it must have Endpoints filled in order to be usable. In the present implementation only the first Endpoint will be used as the bestAddr.

James Tucker	6cfcb3cae4	wgengine/magicsock: fix synchronization of endpoint disco fields ... Identified in review in #7821 endpoint.discoKey and endpoint.discoShort are often accessed without first taking endpoint.mu. The arrangement with endpoint.mu is inconvenient for a good number of those call-sites, so it is instead replaced with an atomic pointer to carry both pieces of disco info. This will also help with #7821 that wants to add explicit checks/guards to disable disco behaviors when disco keys are missing which is necessarily implicitly mostly covered by this change.

Mihai Parparita	f49b9f75b8	util/clientmetric: allow client metric values to be provided by a function ... Adds NewGaugeFunc and NewCounterFunc (inspired by expvar.Func) which change the current value to be reported by a function. This allows some client metric values to be computed on-demand during uploading (at most every 15 seconds), instead of being continuously updated. clientmetric uploading had a bunch of micro-optimizations for memory access (#3331) which are not possible with this approach. However, any performance hit from function-based metrics is contained to those metrics only, and we expect to have very few. Also adds a DisableDeltas() option for client metrics, so that absolute values are always reported. This makes server-side processing of some metrics easier to reason about.

valscale	7bfb7744b7	derp,magicsock: add debug envknobs for HTTP and derp server name (#7744) ... Make developing derp easier by: 1. Creating an envknob telling clients to use HTTP to connect to derp servers, so devs don't have to acquire a valid TLS cert. 2. Creating an envknob telling clients which derp server to connect to, so devs don't have to edit the ACLs in the admin console to add a custom DERP map. 3. Explaining how the -dev and -a command lines args to derper interact. To use this: 1. Run derper with -dev. 2. Run tailscaled with TS_DEBUG_USE_DERP_HTTP=1 and TS_DEBUG_USE_DERP_ADDR=localhost This will result in the client connecting to derp via HTTP on port 3340.

Jordan Whited	f475e5550c	net/neterror, wgengine/magicsock: use UDP GSO and GRO on Linux (#7791) ... This commit implements UDP offloading for Linux. GSO size is passed to and from the kernel via socket control messages. Support is probed at runtime. UDP GSO is dependent on checksum offload support on the egress netdev. UDP GSO will be disabled in the event sendmmsg() returns EIO, which is a strong signal that the egress netdev does not support checksum offload.

Aaron Klotz	90fd04cbde	ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled ... I realized that a lot of the problems that we're seeing around migration and LocalBackend state can be avoided if we drive Windows pref migration entirely from within tailscaled. By doing it this way, tailscaled can automatically perform the migration as soon as the connection with the client frontend is established. Since tailscaled is already running as LocalSystem, it already has access to the user's local AppData directory. The profile manager already knows which user is connected, so we simply need to resolve the user's prefs file and read it from there. Of course, to properly migrate this information we need to also check system policies. I moved a bunch of policy resolution code out of the GUI and into a new package in util/winutil/policy.
