Brad Fitzpatrick 2df38b1feb wgengine/magicsock: quiet log flood at tailscaled shutdown
When you hit control-C on a tailscaled (notably in dev mode, but
also on any systemctl stop/restart), there is a flood of messages like:

magicsock: doing cleanup for discovery key d:aa9c92321db0807f
magicsock: doing cleanup for discovery key d:bb0f16aacadbfd46
magicsock: doing cleanup for discovery key d:b5b2d386296536f2
magicsock: doing cleanup for discovery key d:3b640649f6796c91
magicsock: doing cleanup for discovery key d:71d7b1afbcce52cd
magicsock: doing cleanup for discovery key d:315b61d7e0111377
magicsock: doing cleanup for discovery key d:9301f63dce69bf45
magicsock: doing cleanup for discovery key d:376141884d6fe072
....

It can be hundreds or even tens of thousands.

So don't do that. Not a useful log message during shutdown.

salman eec734a578 ipn/{ipnlocal,localapi}: ensure watcher is installed before /watch-ipn-bus/ responds with 200
This change delays the first flush in the /watch-ipn-bus/ handler
until after the watcher has been successfully installed on the IPN
bus. It does this by adding a new onWatchAdded callback to
LocalBackend.WatchNotifications().

Without this, the endpoint returns a 200 almost immediatly, and
only then installs a watcher for IPN events.  This means there's a
small window where events could be missed by clients after calling
WatchIPNBus().

Fixes tailscale/corp#8594.

Andrew Dunham 3a018e51bb ipn/ipnlocal: move handling of expired nodes to LocalBackend
In order to be able to synthesize a new NetMap when a node expires, have
LocalBackend start a timer when receiving a new NetMap that fires
slightly after the next node expires. Additionally, move the logic that
updates expired nodes into LocalBackend so it runs on every netmap
(whether received from controlclient or self-triggered).

Brad Fitzpatrick c1a2e2c380 net/{packet,tstun},wgengine/filter: fix unknown IP protocol handling
01b90df2fa added SCTP support before
(with explicit parsing for ports) and
69de3bf7bf tried to add support for
arbitrary IP protocols (as long as the ACL permited a port of "*",
since we might not know how to find ports from an arbitrary IP
protocol, if it even has such a concept). But apparently that latter
commit wasn't tested end-to-end enough. It had a lot of tests, but the
tests made assumptions about layering that either weren't true, or
regressed since 1.20. Notably, it didn't remove the (*Filter).pre
bidirectional filter that dropped all "unknown" protocol packets both
leaving and entering, even if there were explicit protocol matches
allowing them in.

Also, don't map all unknown protocols to 0. Keep their IP protocol
number parsed so it's matchable by later layers. Only reject illegal
things.

net/portmapper: relax handling of UPnP resp (#6946)
Gateway devices operating as an HA pair w/VRRP or CARP may send UPnP
replies from static addresses rather than the floating gateway address.
This commit relaxes our source address verification such that we parse
responses from non-gateway IPs, and re-point the UPnP root desc
URL to the gateway IP. This ensures we are still interfacing with the
gateway device (assuming L2 security intact), even though we got a
root desc from a non-gateway address.

This relaxed handling is required for ANY port mapping to work on certain
OPNsense/pfsense distributions using CARP at the time of writing, as
miniupnpd may only listen on the static, non-gateway interface address
for PCP and PMP.

Tom DNetto 673b3d8dbd net/dns,userspace: remove unused DNS paths, normalize query limit on iOS
With a42a594bb3, iOS uses netstack and
hence there are no longer any platforms which use the legacy MagicDNS path. As such, we remove it.

We also normalize the limit for max in-flight DNS queries on iOS (it was 64, now its 256 as per other platforms).
It was 64 for the sake of being cautious about memory, but now we have 50Mb (iOS-15 and greater) instead of 15Mb
so we have the spare headroom.
