Andrew Dunham	8d3acc9235	util/sysresources, magicsock: scale DERP buffer based on system memory This adds the util/sysresources package, which currently only contains a function to return the total memory size of the current system. Then, we modify magicsock to scale the number of buffered DERP messages based on the system's available memory, ensuring that we never use a value lower than the previous constant of 32.

James Tucker	f4da995940	atomicfile: reject overwriting irregular files The intent of atomicfile is to overwrite regular files. Most use cases that would overwrite irregular files, unix sockets, named pipes, devices, and so on are more than likely misuse, so disallow them.

Mihai Parparita	02582083d5	cmd/tsconnect: allow root directory to be passed in #7339 changed the root directory logic to find the ancestor of the cwd with a go.mod file. This works when running the the binary from this repo directly, but breaks when we're a dependency in another repo. Allow the directory to be passed in via a -rootdir flag (the repo that depends on it can then use `go list -m -f '{{.Dir}}' tailscale.com` or similar to pass in the value).

Maisem Ali	e0d291ab8a	ipn/store: add support for stores to hook into a custom dialer For stores like k8s secrets we need to dial out to the k8s API as though Tailscale wasn't running. The issue currently only manifests when you try to use an exit node while running inside a k8s cluster and are trying to use Kubernetes secrets as the backing store. This doesn't address cmd/containerboot, which I'll do in a follow up. Updates #7695 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago

Maisem Ali	985535aebc	net/tstun,wgengine/*: add support for NAT to routes This adds support to make exit nodes and subnet routers work when in scenarios where NAT is required. It also updates the NATConfig to be generated from a `wgcfg.Config` as that handles merging prefs with the netmap, so it has the required information about whether an exit node is already configured and whether routes are accepted.

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.

shayne	7908b6d616	ipn/ipnlocal: [serve] Trim mountPoint prefix from proxy path (#7334 ) This change trims the mountPoint from the request URL path before sending the request to the reverse proxy. Today if you mount a proxy at `/foo` and request to `/foo/bar/baz`, we leak the `mountPoint` `/foo` as part of the request URL's path. This fix makes removed the `mountPoint` prefix from the path so proxied services receive requests as if they were running at the root (`/`) path. This could be an issue if the app generates URLs (in HTML or otherwise) and assumes `/path`. In this case, those URLs will 404. With that, I still think we should trim by default and not leak the `mountPoint` (specific to Tailscale) into whatever app is hosted. If it causes an issue with URL generation, I'd suggest looking at configuring an app-specific path prefix or running Caddy as a more advanced solution.

Andrew Dunham	4cb1bfee44	net/netcheck: improve determinism in hairpinning test If multiple Go channels have a value (or are closed), receiving from them all in a select will nondeterministically return one of the two arms. In this case, it's possible that the hairpin check timer will have expired between when we start checking and before we check at all, but the hairpin packet has already been received. In such cases, we'd nondeterministically set report.HairPinning. Instead, check if we have a value in our results channel first, then select on the value and timeout channel after. Also, add a test that catches this particular failure. Fixes #1795 Change-Id: I842ab0bd38d66fabc6cabf2c2c1bb9bd32febf35 Signed-off-by: Andrew Dunham <andrew@du.nham.ca>	2 years ago
