* From Fang Wang:Guy Harris2009-08-181-0/+3
| | | | | | | | RFC 5482 specifies a new TCP option -- the TCP User Timeout Option (UTO) -- that allows one end of a TCP connection to advertise its current user timeout value. The Kind of UTO option is 28 and the Length is 4. The tcpdump currently does not recognize UTO option.

* The "__attribute__((packed))" tag on structures causes some files not toguy2002-12-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Declare bitfields as "u_int", not "u_char"; ANSI C doesn't guaranteeguy2000-09-291-3/+3
| | | | | | | | that bitfields other than "int" or "unsigned int" are allowed, some compilers warn about them, and, given that the declaration of a bit field says how many bits it is wide, declaring them "u_char" doesn't have any advantage (other than making it a bit clearer, when reading the header, that the bitfields in question are part of a single byte).

Put the declarations of the ICMP stuff directly into "print-icmp.c". Remove all unnecessary includes of <netinet/ip*.h> files. Copy the byte-order stuff from "nameser.h" into "tcp.h".
