IPProto has been being converted to and from string formats in multiple
locations with variations in behavior. TextMarshaller and JSONMarshaller
implementations are now added, along with defined accepted and preferred
formats to centralize the logic into a single cross compatible
implementation.

These log paths were actually unexpected until the refactor in
fe95d81b43. This moves the logs
to the callsites where they are actually unexpected.

The current structure meant that we were embedding netstack in
the tailscale CLI and in the GUIs. This removes that by isolating
the checksum munging to a different pkg which is only called from
`net/tstun`.

This migrates containerboot to reuse the NetfilterRunner used
by tailscaled instead of manipulating iptables rule itself.
This has the added advantage of now working with nftables and
we can potentially drop the `iptables` command from the container
image in the future.

This allows using the fake runner in different packages
that need to manage filter rules.

For the app connector use-case, it doesnt make sense to use listeners, because then you would
need to register thousands of listeners (for each proto/service/port combo) to handle ranges.
Instead, we plumb through the TCPHandlerForFlow abstraction, to avoid using the listeners
abstraction that would end up being a bit messy.

Tailscale attempts to determine if resolvconf or openresolv
is in use by running `resolvconf --version`, under the assumption
this command will error when run with Debian's resolvconf. This
assumption is no longer true and leads to the wrong commands being
run on newer versions of Debian with resolvconf >= 1.90. We can
now check if the returned version string starts with "Debian resolvconf"
if the command is successful.

Just a refactor to consolidate the firewall detection logic in a single
package so that it can be reused in a later commit by containerboot.
Updates #9310
Signed-off-by: Maisem Ali <maisem@tailscale.com>
Add an explicit accept rule for input to the tun interface, as a mirror
to the explicit rule to accept output from the tun interface.
The rule matches any packet in to our tun interface and accepts it, and
the rule is positioned and prioritized such that it should be evaluated
prior to conventional ufw/iptables/nft rules.

This is only relevant for unstable releases and local builds. When local
version is newer than upstream, abort release.
Also, re-add missing newlines in output that were missed in

Updates tailscale/corp#14335
Signed-off-by: Will Norris <will@tailscale.com>
The whois handler was documented as taking IP (e.g. 100.101.102.103)
or IP:port (e.g. usermode 127.0.0.1:1234) but that got broken at some point
and we started requiring a port always. Fix that.
Also, found in the process of adding tests: fix the CapMap lookup in
userspace mode (it was always returning the caps of 127.0.0.1 in
userspace mode). Fix and test that too.

I was reviewing some code that was performing this by hand, and wanted
to suggest using syncs.Map, however as the code in question was
allocating a non-trivial structure this would be necessary to meet the
target.
