ad7546fb9f tailcfg: fix broken test from comment change
Fix broken build from 255c0472fb

"Oh, that's safe to commit because most tests are passing and it's
just a comment change!", I thought, forgetting I'd added a test that
parses its comments.

gofmt in 1.19 is now opinionated about structured text formatting in

wgengine/netstack: only accept connection after dialing (#5503)
If we accept a forwarded TCP connection before dialing, we can
erroneously signal to a client that we support IPv6 (or IPv4) without
that actually being possible. Instead, we only complete the client's TCP
handshake after we've dialed the outbound connection; if that fails, we
respond with a RST.

Updates #5425 (maybe fixes!)

Allows imports of the NPM package added by 1a093ef482
to be replaced with import("http://localhost:9090/pkg/pkg.js"), so that
changes can be made in parallel to both the module and code that uses
it (without any need for NPM publishing or even building of the package).

672c2c8de8 wgengine/magicsock: add filter to ignore disco to old/other ports
Incoming disco packets are now dropped unless they match one of the
current bound ports, or have a zero port*.

The BPF filter passes all packets with a disco header to the raw packet
sockets regardless of destination port (in order to avoid needing to
reconfigure BPF on rebind).

If a BPF enabled node has just rebound, due to restart or rebind, it may
receive and reply to disco ping packets destined for ports other than
those which are presently bound. If the pong is accepted, the pinging
node will now assume that it can send WireGuard traffic to the pinged
port - such traffic will not reach the node as it is not destined for a
bound port.

*The zero port is ignored, if received. This is a speculative defense
and would indicate a problem in the receive path, or the BPF filter.
This condition is allowed to pass as it may enable traffic to flow,
however it will also enable problems with the same symptoms this patch
otherwise fixes.

Fixes #5536

they both at least contain a blockForeverConn. Calling code no longer

net/dnsfallback: cache most recent DERP map on disk (#5545)
This is especially helpful as we launch newer DERPs over time, and older
clients have progressively out-of-date static DERP maps baked in. After
this, as long as the client has successfully connected once, it'll cache
the most recent DERP map it knows about.
