Personal preference (so it's obvious it's not a bool flag), but it
also matches the --state= before it.
Bonus: stop allowing PORT to sneak in extra flags to be passed as
their own arguments, as $FOO and ${FOO} expand differently. (${FOO} is
required to concat to strings)

As the comment in the code says, netstack should always respond to ICMP
echo requests to a 4via6 address, even if the netstack instance isn't
normally processing subnet traffic.

been disabled after intialized.

This doesn't change any behaviour for now, other than maybe running a
full netcheck more often. The intent is to start gathering data on
captive portals, and additionally, seeing this in the 'tailscale
netcheck' command should provide a bit of additional information to
users.

d5e7e309 changed the `hostinfo.GetVersion` from distro and distro version
to UTS Name Release and moved distribution information under
`hostinfo.Distro*`.
`tailscale configure-host` command implementation for Synology DSM
environments relies on the old semantics of this string for matching DSM
Major version so it's been broken for a few days.
Pull in `hostinfo` and prefix match `hostinfo.DistroVersion` to match
DSM major version.

This doesn't change any current magicsock functionality and requires additional

ipnserver previously had support for a Windows-only environment
variable mechanism that further only worked when Windows was running
as a service, not from a console.
But we want it to work from tailscaed too, and we want it to work on
macOS and Synology. So move it to envknob, now that envknob can change
values at runtime post-init.
A future change will wire this up for more platforms, and do something
more for CLI flags like --port, which the bug was originally about.

The GitHub CodeQL scanner flagged the localapi's cert domain usage as a problem
because user input in the URL made it to disk stat checks.
The domain is validated against the ipnstate.Status later, and only
authenticated root/configured users can hit this, but add some
paranoia anyway.

The data that we send over WebSockets is encrypted and thus not

As noted in #5617, our documented method of blocking log.tailscale.io
DNS no longer works due to bootstrap DNS.
Instead, provide an explicit flag (--no-logs-no-support) and/or env
variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher
uploads. It also sets a bit on Hostinfo to say that the node is in that
mode so we can end any support tickets from such nodes more quickly.
This does not yet provide an easy mechanism for users on some
platforms (such as Windows, macOS, Synology) to set flags/env. On
Linux you'd used /etc/default/tailscaled typically. Making it easier
to set flags for other platforms is tracked in #5114.

This change masks the bitspace used when setting and querying the fwmark on packets. This allows
tailscaled to play nicer with other networking software on the host, assuming the other networking
software is also using fwmarks & a different mask.
IPTables / mark module has always supported masks, so this is safe on the netfilter front.
However, busybox only gained support for parsing + setting masks in 1.33.0, so we make sure we
arent such a version before we add the "/<mask>" syntax to an ip rule command.

The `tailscale web` UI is the primary interface for Synology and Home
Assistant users (and perhaps others), so is the logical place to put our

currently a very minimal UI, but I'm not sure of a better option.
