Fix relay re-establishment for handshake on Disestablised entry ( #1805 )
...
handleOutsideRelayPacket filled ViaSender.remoteIdx with relay.RemoteIndex,
an index from the relay peer's index space, but the rescue in
sendHandshakeResponse looks that value up in relayForByIdx, which is keyed
by local index. The lookup could never hit, so a terminal relay entry left
Disestablished by a one-sided teardown stayed Disestablished even after a
valid handshake arrived over it. The responder's first transmit then failed
to find an Established relay, deleted its only relay entry, and every
subsequent send was silently dropped until dead-tunnel detection forced a
re-handshake.

The Nebula Wireshark dissector uses bit32.band() when parsing the
Nebula packet type. On Wireshark builds using Lua 5.4, bit32 is not
available, which causes dissection to fail with:
Lua Error: nebula.lua:65: attempt to index a nil value (global 'bit32')
Wireshark bundles Lua BitOp and exposes it globally as bit for Lua
dissectors. This is the documented API for maximum backwards
compatibility across supported Lua versions.
Use bit.band() instead of bit32.band().

* cleanup ipv6 iputil helpers
With my refactoring in this PR I accidentally had some duplicate logic,
this PR cleans it up:
- https://github.com/slackhq/nebula/pull/1766
* skip ICMP reject for ICMP error packets and fragments
Per RFC 1122, ICMP error messages must not be generated in response to
other ICMP error messages to prevent infinite error loops. This applies
to both IPv4 (types 3, 4, 5, 11, 12) and IPv6 (types 1-4).
Do not generate reject packets for IPv4 or IPv6 fragments. For IPv4,
check MF flag and fragment offset. For IPv6, add isFragment return to
ipv6FindUpperProtocol so a single traversal handles both protocol
lookup and fragment detection.
* do send rejects for the initial fragment
RFC says "non-initial fragment"s
* fix fragment checks
