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.

Andrew Dunham	8d3acc9235	util/sysresources, magicsock: scale DERP buffer based on system memory ...

James Tucker	a31e43f760	go.mod: bump gvisor to 20230320 for dispatcher locking ... Upstream improved code around an issue showing up in CI, where sometimes shutdown will race on endpoint.dispatcher being nil'd, causing a panic down stack of injectInbound. The upstream patch makes some usage more safe, but it does not itself fix the local issue. See panic in https://github.com/tailscale/tailscale/actions/runs/4548299564/jobs/8019187385#step:7:843 See fix in google/gvisor@13d7bf69d8 Updates #7715 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
James Tucker	c628132b34	wgengine/netstack: do not send packets to netstack after close ... Use the local context on Impl to check for shut down state in order to drop rather than inject packets after close has begun. Netstack sets endpoint.dispatcher to nil during shutdown. After the recent adjustment in 920ec69241 we now wait for netstack to fully shutdown before we release tests. This means that we may continue to accept packets and attempt to inject them, which we must prevent in order to avoid nil pointer panic.
