| | | | | | | | | | | | | | the wire; the definitions in many systems use u_long, which is 64 bits long on many platforms - that's OK for in-memory structures, but it doesn't match what's on the wire. Use headers based on the Sun ones, but use u_int32_t for fields, and otherwise make the structures match what's on the wire, and change some names to avoid collision with <rpc/rpc.h>, which print-sunrpc.c includes to declare "getrpcbynumber()" and the structure it returns. Record whether "getrpcbynumber()" is found, and use it only if it's found, rather than basing the decisison on whether we're building for Win32 or not.

| | | | | | | | | | | | | | | | | run past the end of that payload. Check that the IPv4 total length isn't less than the header length. Use "%u", not "%d", to print unsigned values. Properly update "len" in the header-processing loop for IPv6. Doing so means we can trust the length passed to the TCP and UDP dissectors when constructing the IPv6 pseudo-header; do so (but fix the length we pass to the UDP-over-IPv6 checksum routine). That length is unsigned; make the corresponding arguments to the TCP and UDP checksum routines unsigned.

Undo the rcsid-shuffling and addition of extra #includes, as we no longer need to arrange that "interface.h" be included before using _U_ in an RCS ID or copyright.
* From Neil Spring:guy2003-11-151-4/+4
| | | | | | | | | | | use "_U_" in the definitions of "rcsid[]", to eliminate complaints about those variables being unused; move the definitions after the include of "interface.h", or add an include of "interface.h", so that "_U_" is defined.

* Updates from Bruce Simpson:guy2003-09-121-10/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fix numerous bugs in my AODV submission, red faces all round, mainly due to misunderstanding of EXTRACT_STRING() macro arguments (because these are macros, type checking didn't happen). AODV HELLO extensions are now correctly printed. The code is closer to FreeBSD's style guidelines. Don't use "u_char" and "u_long", use "u_int8_t" and "u_int32_t". "u_long" is definitely wrong as it's 64 bits on some platforms; "u_char" is safe, but the official tcpdump style uses "u_int8_t". At least according to the (long-since-expired) draft-perkins-aodv6-01, the V6 AODV messages have different message type values from the V4 ones in draft-ietf-manet-aodv-13. However, draft-ietf-manet-aodv-13 says that the only differences are in the addresses; we support both. Clean up the way we tell the AODV6 dissector that we're running atop IPv6 a bit. Use "udpipaddr_print()" if we're printing AODV packets as a result of saying "anything that matches this filter is AODV", rather than doing it ourselves under the assumption that it's running over IPv4.

| | | | | | | | | | | | | an out-of-range flag value. Seperate out the truncation checks into two: are the ports available, then do all the other checks, then check to see if the full UDP header is available. This is a slightly modified version of Alexander's original patch to instead use udpipaddr_print() to print the addresses if the ports are not available.

* The "__attribute__((packed))" tag on structures causes some files not toguy2002-12-111-35/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | unused-parameter problems reported by GCC. Add an _U_ tag to label parameters as unused if the function is called through a pointer (so that you can't change its signature by removing parameters) or if there are unused parameters only because the function isn't complete. Add some additional bounds checks the necessity for which was revealed while cleaning up unused-parameter problems. Make some routines static. "lcp_print()", defined in "print-lcp.c", isn't called anywhere - "print-ppp.c" has the code to dissect LCP. Get rid of "print-lcp.c".

Replace the include of <arpa/nameser.h> in "print-rx.c" with an include of "nameser.h", and "#if 0" it out pending a determination of whether it's necessary (why would AFS's RX care about the internals of DNS packets?) or not.

| | | | | | | | | | checksum, fetch it by casting the pointer to "const u_int8_t *" rather than "const char *" - casting it to "const char *" causes it to be sign-extended, perhaps causing 16 1 bits to be added in at the top and, at least on big-endian platforms (where "htons()" does nothing, meaning it won't trim off the extra 16 bits) with signed "char"s (e.g., SPARC), causing the checksum to be computed incorrectly and causing it to incorrectly be reported as bad.
