-replace private flag printers and replace them with bittok2str()
-remove some flesh from inline printf() statements make more use of tok2str()
-option printer gets a multiline output (behind vflag)
-context hexdump for options
-replace some u_int32 with u_int8[4] to get around compiler padding issues
with the current IANA assignment (Apr 13 2004). It consists of the
following four parts:
- added inverse-neighbor-discovery (RFC3122)
- shift MTRACE-related type numbers, since it collides
with inverse-neighbor-discovery.
- added MLDv2 (draft-vida-mld-v2-08.txt)
- shifted Mobile-IPv6 numbers from interim value to the
official one. (draft-ietf-mobile-ipv6-24.txt)
compile with Sun C, as "interface.h" isn't being included before the
structures are being declared.
Furthermore, in the files that Sun C *can* compile, it doesn't cause Sun
C to generate code that's safe with unaligned accesses, as
"__attribute__" is defined as a do-nothing macro with compilers that
don't support it.
Therefore, we get rid of that tag on the structures to which it was
added, and instead use "EXTRACT_16BIT()" and "EXTRACT_32BIT()" to fetch
16-bit and 32-bit big-endian quantities from packets. We also fix some
other references to multi-byte quantities to get rid of code that tries
to do unaligned loads on platforms that don't support them.
We also throw in a hack that makes those macros use
"__attribute__((packed))" on structures containing only one 16-bit or
32-bit integer to get the compiler to generate unaligned-safe code
rather than doing it by hand. (GCC on SPARC produces the same code that
doing it by hand does; I don't know if GCC on any other big-endian
strict-alignment processor generates better code for that case. On
little-endian processors, as "ntohs()" and "ntohl()" might be functions,
that might actually produce worse code.)
Fix some places to use "%u" rather than "%d" to print unsigned
quantities.
ip6.h is almost normal RFC2292 header.
icmp6.h has couple of extensions (not covered by RFC2292),
like MLD, ICMPv6 nodeinfo, and router renumber.
XXX how to synchronize with future kame changes?
