I've come across a bug in the 6LoWPAN header decompression code that
incorrectly computes the length of IPv6 extension headers by adding the
protocol and length fields twice.
svn path=/trunk/; revision=32157
This patch fixes 6LoWPAN fragmentation to comply with RFC4944.
I also happened across a problem with the derivations of
interface identifiers from 16-bit IEEE 802.15.4 addresses, which
should also be fixed in my patch.

This patch fixes a bug in the 6LoWPAN dissectors that corrupts addresses when
multicast address compression is used. Testing this fix also uncovered a bug in
the computation of the length of the extension headers. And some typos.

This patch fixes a bug in the 6LoWPAN dissector where link-local addresses
created from an EUI-64 address do not correctly invert the universal/local bit
as recommended by section 4 of RFC2464.

When a 6lowpan message has a compressed UDP length (i.e. the length must be
calculated, not read from the headers), the 6lowpan dissector correctly reports
that the UDP length is compressed, but it may try to read the length from the
headers anyway.

We've discovered a number of bugs in the 6LoWPAN dissector,
and have fixed them in the following patch. The fixed bugs include:
- Incorrect UDP Checksum calculation.
- Incorrect link-local prefix when decompressing IPHC headers.
- Incorrect parsing of the UDP port numbers when not 8-byte aligned.
- Overflow of the datagram offset field when reassembling fragmented packets.

The attached patch adds a dissector for IPv6 over IEEE 802.15.4 (aka 6LoWPAN).
The protocol is specified in RFC 4944. This dissector also processes the
6LoWPAN draft header compression scheme in draft-ietf-6lowpan-hc-05.
