Part of unforking our winipcfg-go and using upstream (#760), move our
additions into our repo. (We might upstream them later if upstream has
interest)
Originally these were:
@apenwarr: "Add ifc.SyncAddresses() and SyncRoutes()."
609dcf2df5
@bradfitz: "winipcfg: make Interface.AddRoutes do as much as possible, return combined error"
e9f93d53f3
@bradfitz: "prevent unnecessary Interface.SyncAddresses work; normalize IPNets in deltaNets"
decb9ee8e1
Might fix it. I've spent too much time failing to reproduce the issue. This doesn't
seem to make it worse, though (it still runs for me), so I'll include this and
see if it helps others while I still work on a reliable way to reproduce it.
Updates tailscale/corp#474
Otherwise when PAC server is down, we log, and each log entry is a new
HTTP request (from logtail) and a new GetProxyForURL call, which again
logs, non-stop. This is also nicer to the WinHTTP service.
Then also hook up link change notifications to the cache to reset it
if there's a chance the network might work sooner.
We depend on DERP for NAT traversal now[0] so disabling it entirely can't
work.
What we'll do instead in the future is let people specify
alternate/additional DERP servers. And perhaps in the future we could
also add a pref for nodes to say when they expect to never need/want
to use DERP for data (but allow it for NAT traversal communication).
But this isn't the right pref and it doesn't work, so delete it.

This change is to restore /etc/resolv.conf after tailscale down is called. This is done by setting the dns.Manager before errors occur. Error collection is also added.
Fixes#723
DebugForceDisco was a development & safety knob during the the transition
to discovery. It's no longer needed.
Add MapRequest.ReadOnly to prevent clients needing to do two
peer-spamming MapRequest at start-up.
This only adds the field, not the use of the field. (The control server
needs to support it first.)

There's often some useful piece of information in there not already
repeated in the internal error.

It's properly handled later in tsdns.NewMap anyway, but there's work
done in the meantime that can be skipped when a peer lacks a DNS name.
It's also more clear that it's okay for it to be blank.

Also remove rebinding logic from the windows router. Magicsock will
instead rebind based on link change signals.

I had to use
go get -u github.com/tailscale/depaware@e09ee10c18249e4bf198e66bbd47babcd502637a
to force it to the correct version; it kept selecting head~1.
Maybe because the branch is called main instead of master?
Maybe because of some delay?
Updates #654. See that issue for a discussion of why
this timeout reduces flakiness, and what next steps are.

For now. Get it working again so it's not stuck on 0.98.
Subnet relay can come later.
