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.

cmd/tailscale/cli: make serve and funnel visible in list (#7737) 2 years ago
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 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

Maisem Ali be027a9899 control/controlclient: improve handling of concurrent lite map requests
This reverts commit 6eca47b16c and fixes forward.

Previously the first ever streaming MapRequest that a client sent would also
set ReadOnly to true as it didn't have any endpoints and expected/relied on the
map poll to restart as soon as it got endpoints. However with 48f6c1eba4,
we would no longer restart MapRequests as frequently as we used to, so control
would only ever get the first streaming MapRequest which had ReadOnly=true.

Control would treat this as an uninteresting request and would not send it
any further netmaps, while the client would happily stay in the map poll forever
while litemap updates happened in parallel.

This makes it so that we never set `ReadOnly=true` when we are doing a streaming
MapRequest. This is no longer necessary either as most endpoint discovery happens
over disco anyway.

Mihai Parparita 9cb332f0e2 sockstats: instrument networking code paths
Uses the hooks added by tailscale/go#45 to instrument the reads and
writes on the major code paths that do network I/O in the client. The
convention is to use "<package>.<type>:<label>" as the annotation for
the responsible code path.

Enabled on iOS, macOS and Android only, since mobile platforms are the
ones we're most interested in, and we are less sensitive to any
throughput degradation due to the per-I/O callback overhead (macOS is
also enabled for ease of testing during development).

For now just exposed as counters on a /v0/sockstats PeerAPI endpoint.

We also keep track of the current interface so that we can break out
the stats by interface.
