* Process VLAN frames and Alteon jumbo frames in the Ethernet printer.Guy Harris2010-02-211-89/+86
| | | | | | | | | | | | | | | | | Instead of having the Ethernet-type handler process the VLAN and Alteon jumbo frame Ethernet type values, process them in the Ethernet (and Linux cooked-mode) dissectors. This makes it easier for the right MAC addresses to be printed for those packets. As part of that, rename ether_encap_print() to ethertype_print() - it doesn't print encapsulated Ethernet frames, it prints payloads whose packet type is indicated by an Ethernet type field value - and remove the no-longer-needed "extracted Ethernet type" argument. That also lets us eliminate it from the SNAP print routine. Make ether_print() take a function, and an argument to pass to that function, as parameters, so that, for example, the ATM LANE printer can use it and put the LEC ID into the link-layer headeer printout.
* Don't directly fetch multi-byte integers from packets.Guy Harris2010-02-211-13/+20
| | | | | | | | Use the EXTRACT_ macros to extract multi-byte integral values from packets, rather than just dereferencing pointers into the packet; there is no guarantee that the packet data will be aligned on the right boundary, and there is no guarantee that, if they're not, a direct access will work correctly.

| | | | | | | | | | | | | | having its callers do so - some of its callers *weren't* doing so, leaving random junk in that argument in some cases. When checking for "802.3-encapsulated" IPX, check the raw values of the SSAP and DSAP for 0xFF, don't check them after the low-order bit has been masked off. The "flag" values in the LLC header aren't bits, they're combinations of bits, including the combination "no bits"; don't use "bittok2str()" on them. Also, combine the proper bits, namely the C/R bit (which we weren't combining) and the P/F bit (which we were).

| | | | | | | | link-layer print routines if no other print routine claimed the packet. Test whether that flag is set rather than testing whether neither of -x or -q were specified, and have -x, -q, *and* -X set that flag, so that -X suppresses it just as -x does. That way you don't get those pckets dumped twice if -X was specified.

* Have the configure script arrange that the Makefile define _U_guy2003-11-161-4/+4
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | beginning of the raw packet data, the captured length of the raw packet data, and the length of the link-layer header, and: if "-e" was specified, prints all the raw packet data; if "-e" was not specified, prints all the raw packet data past the link-layer header, if there is any. Use that routine in all the "xxx_if_print()" routines if "-x" was specified. Make "arcnet_encap_print()" static - it's not used outside "print-arcnet.c". Add missing info printing code to "atm_if_print()". Print the packet data in "lane_if_print()", not in "lane_print()", as "lane_print()" can be called from other "xxx_if_print()" routines, and those routines will also print the packet data if "-x" was specified - no need to print it twice.
* We no longer use "packetp" for anything, so eliminate it. (If anyguy2002-12-181-6/+4
| | | | | | | | | | | | | dissector really needs source and destination MAC addresses, we should make global pointers to them - which would be null for packets lacking MAC addresses, so dissectors that need them will need to do something sensible if those pointers are null.) Don't fake up an Ethernet header if there aren't any MAC addresses to use when faking it up. "bp_chaddr" in "print-bootp.c" is an array, so "bp->bp_chaddr" cannot be null, and there's no need to test for it not being null.

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".
