* The peer polling interval is an exponent; treat it as such.peppe2012-11-121-1/+1
| | | | | | | | | | | | | | | | RFC 1119 says Peer Poll Interval (peer.ppoll, pkt.ppoll): This is a signed integer indicating the minimum interval between messages sent by the peer, in seconds as a power of two. For instance, a alue of six indicates a minimum interval of 64 seconds. so print both the raw value and 2^{raw value}, showing the latter. Patch from Debian bug 686276.

* Add an "fn_printzp()" routine for printing null-padded strings (stringsguy2005-05-061-2/+3
| | | | | | | | | | | | | | | with a maximum length, where a string shorter than that length is padded with NULs), as "fn_print()" won't handle the maximum length *and* the snapshot length and "fn_printn()" won't stop on a null string. Use it where appropriate. Always pass "snapend" to "fn_print()" and "fn_printn()" if they're passed a pointer into the packet data; only pass NULL if they're being handed a pointer into a buffer that's not part of the packet data. Always check the return value of "fn_print()", "fn_printn()", and "fn_printzp()" if they're passed "snapend", and do the appropriate string termination and "packet truncated" indication if they return 1.

| | | | | | | | | | appropriately, and that GNUmakefile and the MSVC++ project file define it apppriately, as we do with libpcap, rather than defining it in "interface.h". 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. Include "config.h" before including "tcpdump-stdinc.h" in "missing/datalinks.c".

* The "__attribute__((packed))" tag on structures causes some files not toguy2002-12-111-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Move other stuff used by dissectors from <netinet/if_ether.h> to "ether.h", along the lines of "fddi.h" and "token.h". Move ARP declarations from BSD include files to "print-arp.c". Remove from dissectors includes of <netinet/if_ether.h>, and add includes of "ethertype.h" and/or "ether.h" as necessary. Get rid of configuration options that test declarations now made in "ether.h" or "print-arp.c", as those declarations are now under our control, not the OS's control.
