1e28207a15 types/logger: fix rateFree interaction with verbosity prefixes
We log lines like this:

c.logf("[v1] magicsock: disco: %v->%v (%v, %v) sent %v", c.discoShort, dstDisco.ShortString(), dstKey.ShortString(), derpStr(dst.String()), disco.MessageSummary(m))

The leading [v1] causes it to get unintentionally rate limited.
Until we have a proper fix, work around it.

Fixes #1216

tailcfg: update node display name fields and methods (#1207)
Signed-off-by: Sonia Appasamy <sonia@tailscale.com>

Consolidates the node display name logic from each of the clients into
tailcfg.Node. UI clients can use these names directly, rather than computing
them independently.

4fea604979 wgengine/router: stop setPrivateNetwork goroutine on configureInterface failure
On Windows, configureInterface starts a goroutine reconfiguring the
Windows firewall.

But if configureInterface fails later, that goroutine kept running and
likely failing forever, spamming logs. Make it stop quietly if its
launching goroutine filed.

d5baeeed5c wgengine: use Tailscale-style peer identifiers in logs
Rewrite log lines on the fly, based on the set of known peers.

This enables us to use upstream wireguard-go logging,
but maintain the Tailscale-style peer public key identifiers
that the rest of our systems (and people) expect.

Continuation of earlier two umask changes,

d6e9fb1df0.

This change mostly affects us, running tailscaled as root by hand (wit
a umask of 0077), not under systemd. End users running tailscaled
under systemd won't have a umask.

d3dd7c6270 wgengine/magicsock: make legacy DstToString match Addrs
DstToString is used in two places in wireguard-go: Logging and uapi.

We are switching to use uapi for wireguard-go config.
To preserve existing behavior, we need the full set of addrs.

And for logging, having the full set of addrs seems useful.

(The Addrs method itself is slated for removal. When that happens,
the implementation will move to DstToString.)

5fe5402fcd Revert "wgengine/magicsock: shortcircuit discoEndpoint.heartbeat when its connection is closed"
This reverts commit 08baa17d9a.
It caused deadlocks due to lock ordering violations.
It was not the right fix, and thus should simply be reverted
while we look for the right fix (if we haven't already found it
in the interim; we've fixed other logging-after-test issues).
