d5781f61a9 ipn/ipnlocal: return usernames when Tailscale SSH is enabled
It was checking if the sshServer was initialized as a proxy, but that
could either not have been initialized yet or Tailscale SSH could have
been disabled after intialized.

Also bump tailcfg.CurrentCapabilityVersion

net/netcheck: add check for captive portal (#5593)
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.

ff13c66f55 cmd/tailscale: fix configure-host command for Synology
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.

65c24b6334 envknob: generalize Windows tailscaled-env.txt support
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.

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.

45a3de14a6 cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support
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.

f6da2220d3 wgengine: set fwmark masks in netfilter & ip rules
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.
