Naman SoodandGitHub 6301a6ce4b util/linuxfw,wgengine/router: allow incoming CGNAT range traffic with nodeattr
Clients with the newly added node attribute
`"disable-linux-cgnat-drop-rule"` will not automatically drop inbound
traffic on non-Tailscale network interfaces with the source IP in the
CGNAT IP range. This is an initial proof-of-concept for enabling
connectivity with off-Tailnet CGNAT endpoints.

Fixes tailscale/corp#36270.

Naman SoodandGitHub f157f3288d cmd/tailscale/cli,ipn/conffile: add declarative config mode for Services (#17435)
This commit adds the subcommands `get-config` and `set-config` to Serve,
which can be used to read the current Tailscale Services configuration
in a standard syntax and provide a configuration to declaratively apply
with that same syntax.

Both commands must be provided with either `--service=svc:service` for
one service, or `--all` for all services. When writing a config,
`--set-config --all` will overwrite all existing Services configuration,
and `--set-config --service=svc:service` will overwrite all
configuration for that particular Service. Incremental changes are not
supported.

Fixes tailscale/corp#30983.

Naman SoodandGitHub 04d24cdbd4 wgengine/netstack: correctly proxy half-closed TCP connections
TCP connections are two unidirectional data streams, and if one of these
streams closes, we should not assume the other half is closed as well.
For example, if an HTTP client closes its write half of the connection
early, it may still be expecting to receive data on its read half, so we
should keep the server -> client half of the connection open, while
terminating the client -> server half.

Naman SoodandGitHub a4b8c24834 ipn: sort VIP services before hashing (#15035)
We're computing the list of services to hash by iterating over the
values of a map, the ordering of which is not guaranteed. This can cause
the hash to fluctuate depending on the ordering if there's more than one
service hosted by the same host.

* tailcfg: rename and retype ServiceHost capability, add value type

Updates tailscale/corp#22743.

In #14046, this was accidentally made a PeerCapability when it
should have been NodeCapability. Also, renaming it to use the
nomenclature that we decided on after #14046 went up, and adding
the type of the value that will be passed down in the RawMessage
for this capability.

This shouldn't break anything, since no one was using this string or
variable yet.

Updates #9084.

Currently, we have to tell users to manually open UDP ports on Linux when
certain firewalls (like ufw) are enabled. This change automates the process of
adding and updating those firewall rules as magicsock changes what port it
listens on.
