db800ddeac cmd/derper: set Content-Security-Policy on DERPs.
It's a basic "deny everything" policy, since DERP's HTTP

"dangerously configured" HTTP servers.

73beaaf360 net/tstun: rate limit "self disco out packet" logging
When this happens, it is incredibly noisy in the logs.
It accounts for about a third of all remaining
"unexpected" log lines from a recent investigation.

It's not clear that we know how to fix this,
we have a functioning workaround,
and we now have a (cheap and efficient) metric for this
that we can use for measurements.

So reduce the logging to approximately once per minute.

ad5e04249b wgengine/monitor: ignore adding/removing uninteresting IPs
One of the most common "unexpected" log lines is:

"network state changed, but stringification didn't"

One way that this can occur is if an interesting interface
(non-Tailscale, has interesting IP address)
gains or loses an uninteresting IP address (link local or loopback).

The fact that the interface is interesting is enough for EqualFiltered
to inspect it. The fact that an IP address changed is enough for
EqualFiltered to declare that the interfaces are not equal.

But the State.String method reasonably declines to print any
uninteresting IP addresses. As a result, the network state appears
to have changed, but the stringification did not.

The String method is correct; nothing interesting happened.

This change fixes this by adding an IP address filter to EqualFiltered
in addition to the interface filter. This lets the network monitor
ignore the addition/removal of uninteresting IP addresses.

ca1b3fe235 net/tshttpproxy: use correct size for Windows BOOL argument
The Windows BOOL type is an int32. We were using a bool,
which is a one byte wide. This could be responsible for the
ERROR_INVALID_PARAMETER errors we were seeing for calls to
WinHttpGetProxyForUrl.

We manually checked all other existing Windows syscalls
for similar mistakes and did not find any.

7d8feb2784 hostinfo: change Windows implementation to directly query version information using API and registry
We replace the cmd.exe invocation with RtlGetNtVersionNumbers for the first
three fields. On Windows 10+, we query for the fourth field which is available
via the registry.

The fourth field is not really documented anywhere; Firefox has been querying
it successfully since Windows 10 was released, so we can be pretty confident in
its longevity at this point.

1a629a4715 net/portmapper: mark fewer PMP probe failures as unexpected
There are lots of lines in the logs of the form:

portmapper: unexpected PMP probe response: {OpCode:128 ResultCode:3
SecondsSinceEpoch:NNN MappingValidSeconds:0 InternalPort:0
ExternalPort:0 PublicAddr:0.0.0.0}

ResultCode 3 here means a network failure, e.g. the NAT box itself has
not obtained a DHCP lease. This is not an indication that something
is wrong in the Tailscale client, so use different wording here
to reflect that. Keep logging, so that we can analyze and debug
the reasons that PMP probes fail.
