* remove tcpdump's own CVS keywordsDenis Ovsienko2014-01-031-2/+0
| | | | | | Remove lots of $Header's and a few $Id's that all belong to the former CVS repository of tcpdump itself. These keywords have been frozen since the migration to git in late 2008.
* There's another Cisco-private encapsulation of BPDUs.Guy Harris2013-04-131-0/+1
| | | | | At least according to the Wireshark STP dissector, SNAP frames with the Cisco OUI and a PID of 0x010c contain BPDUs, for "VLAN Bridge".

* Make "snap_print()" handle fetching and printing the OUI.guy2005-04-261-34/+2
| | | | | | | | | | | | | | | | | | Don't copy the LLC header to a "struct llc", just construct the individual fields. Fetch the control field early in the dissection process, and check to make sure we have at least 4 bytes of LLC header if it's not a U frame. Fetch both bytes of the control field for I and S frames, and display all 4 hex digits of it. Only dissect UI frames as BPDUs, and pass the BPDU dissector a pointer to the beginning of the BPDU, not the beginning of the LLC header - not all BPDUs are encapsulated in LLC headers. Only dissect UI frames as IP packets. Do bounds checking in "snap_print()".

* 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.
