9af27ba829 cmd/cloner: mangle "go:generate" in cloner.go
The "go generate" command blindly looks for "//go:generate" anywhere
in the file regardless of whether it is truly a comment.
Prevent this false positive in cloner.go by mangling the string
to look less like "//go:generate".

aae622314e tailcfg, health: add way for control plane to add problems to health check
So if the control plane knows that something's broken about the node, it can
include problem(s) in MapResponse and "tailscale status" will show it.
(and GUIs in the future, as it's in ipnstate.Status/JSON)

This also bumps the MapRequest.Version, though it's not strictly
required. Doesn't hurt.

types/key: add a special key with custom serialization for control private keys (#2792)
* Revert "Revert "types/key: add MachinePrivate and MachinePublic.""

This reverts commit 61c3b98a24.

Signed-off-by: David Anderson <danderson@tailscale.com>

* types/key: add ControlPrivate, with custom serialization.

ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.

597fa3d3c3 tailcfg/derpmap: add flag to omit ts's derps
This adds a flag to derp maps which specifies that default Tailscale DERP servers should not be
used. If true and there are entries in this map, it indicates that the entries in this map
should take precedent and not hit any of tailscale's DERP servers.

This change is backwards compatible, as the default behavior should be false.

34d2f5a3d9 tailcfg: add Endpoint, EndpointType, MapRequest.EndpointType
Track endpoints internally with a new tailcfg.Endpoint type that
includes a typed netaddr.IPPort (instead of just a string) and
includes a type for how that endpoint was discovered (STUN, local,
etc).

Use []tailcfg.Endpoint instead of []string internally.

At the last second, send it to the control server as the existing
[]string for endpoints, but also include a new parallel
MapRequest.EndpointType []tailcfg.EndpointType, so the control server
can start filtering out less-important endpoint changes from
new-enough clients. Notably, STUN-discovered endpoints can be filtered
out from 1.6+ clients, as they can discover them amongst each other
via CallMeMaybe disco exchanges started over DERP. And STUN endpoints
change a lot, causing a lot of MapResposne updates. But portmapped
endpoints are worth keeping for now, as they they work right away
without requiring the firewall traversal extra RTT dance.

End result will be less control->client bandwidth. (despite negligible
increase in client->control bandwidth)

control/controlclient: sign RegisterRequest (#1549)
control/controlclient: sign RegisterRequest

Some customers wish to verify eligibility for devices to join their
tailnets using machine identity certificates. TLS client certs could
potentially fulfill this role but the initial customer for this feature
has technical requirements that prevent their use. Instead, the
certificate is loaded from the Windows local machine certificate store
and uses its RSA public key to sign the RegisterRequest message.

There is room to improve the flexibility of this feature in future and
it is currently only tested on Windows (although Darwin theoretically
works too), but this offers a reasonable starting place for now.

56a7652dc9 wgkey: new package
This is a replacement for the key-related parts
of the wireguard-go wgcfg package.

This is almost a straight copy/paste from the wgcfg package.
I have slightly changed some of the exported functions and types
to avoid stutter, added and tweaked some comments,
and removed some now-unused code.

To avoid having wireguard-go depend on this new package,
wgcfg will keep its key types.

We translate into and out of those types at the last minute.
These few remaining uses will be eliminated alongside
the rest of the wgcfg package.

d21956436a ipn, tailcfg: change Windows subnet disabling behavior w/ WPAD
In 1.0, subnet relays were not specially handled when WPAD+PAC was
present on the network.

In 1.2, on Windows, subnet relays were disabled if WPAD+PAC was
present. That was what some users wanted, but not others.

This makes it configurable per domain, reverting back to the 1.0
default state of them not being special. Users who want that behavior
can then enable it.

0e3048d8e0 control/controlclient: support delta userprofiles from control
I was going to make support for this advertised from the client, but
turns out only "tailscale status" even uses the UserProfiles field and
fails gracefully (omits that field) if a user profile for a user is
missing, so I think we can just reuse the DeltaPeers field from the
client to ask the control server to also delta encode the user
profiles.

For the few users running 1.1.x (unstable) versions between DeltaPeers
support (1.1.82) and this (~1.1.541), they'll just sometimes have
missing names in "tailscale status --json" or "tailscale status --web"
(the only places the UserProfile is used).

e6b84f2159 all: make client use server-provided DERP map, add DERP region support
Instead of hard-coding the DERP map (except for cmd/tailscale netcheck
for now), get it from the control server at runtime.

And make the DERP map support multiple nodes per region with clients
picking the first one that's available. (The server will balance the
order presented to clients for load balancing)

This deletes the stunner package, merging it into the netcheck package
instead, to minimize all the config hooks that would've been
required.

Also fix some test flakes & races.

65fbb9c303 wgengine/filter: support subnet mask rules, not just /32 IPs.
This depends on improved support from the control server, to send the
new subnet width (Bits) fields. If these are missing, we fall back to
assuming their value is /32.

Conversely, if the server sends Bits fields to an older client, it will
interpret them as /32 addresses. Since the only rules we allow are
"accept" rules, this will be narrower or equal to the intended rule, so
older clients will simply reject hosts on the wider subnet (fail
closed).

With this change, the internal filter.Matches format has diverged
from the wire format used by controlclient, so move the wire format
into tailcfg and convert it to filter.Matches in controlclient.
