handle that file not ending with a 2-byte 0xffff end-of-file record.
This fixes bug 9455, although it doesn't add support for reading an
"index" file for a capture that's in multiple .rf5 files, which is a
separate issue noted in that bug.
It also doesn't attempt to figure out what the data in the new record
type following the data that appears to be the same as that in the other
data record format but preceding the actual packet data is.

in a source description record, including the stack. Dump some other
fields in those records as well.
Attach separate sequential and random read buffers to the private data
structure, rather than allocating them in various routines (and not
always freeing them) and, in at least one case, allocating a single
*common* buffer for all wth's to use.
Fix some comments (the DS0 mask is 32 bytes long, but gets turned into a
bitmask).
Put in a description of what a "stack file"'s contents look like. Much
of it may be useless to us (for example, we have the notion that TCP has
protocol number 6 built-in...), but the RELATION entries that map from
"BASE" to a protocol could obviate the need to have the user specify a
map from stack file names to starting protocols, and we might be able to
use, for example, entries that map TCP/UDP/SCTP port numbers to
protocols to obviate the need for the user to explicitly use Decode As
or otherwise configure port-to-protocol mappings themselves.
Add a bunch of record length checks before we fetch data from records.

Dump the raw contents of records as hex and ASCII, not just hex.
Sort the record types, and add a new one for a type we've seen in a k18
file and about which we know nothing.
For unknown record types, print the type in hex.

Add support for dissection ELF files. It opens as a "capture" file via wiretap
at the moment for simplicity's sake, but the intention is eventually to have
this (and other file types we dissect) open through some other program sharing
much of the libwireshark infrastructure.

actual line of code is causing the problem. Maybe the patch submitter can identify the problem).

whether the (zero-based) interface ID is < the number of interface IDs,
so we don't need to do so in pcapng_read().
Unions are tricky - if the compiler doesn't ensure that the right
component of the union is being used at any given time, various problems
can happen.
Remove some members from the "data" union in the wtapng_block_t

While we're at it, pcapng_read_packet_block() and
pcapng_read_simple_packet_block() return an integer, not a Boolean;
return 0, not FALSE (they have the same value, but returning 0 makes it
clearer that the return value isn't restricted to TRUE or FALSE).

include only extensions used mostly by capture files (i.e., not ".txt"
or ".xml"), and list each extension set only once (it's silly to have,
for example, separate entries for NetMon, Shomiti Surveyor, and
NetScaler with ".cap" when you get all those types no matter which entry
you choose).

the "All Files" entry (the current UI guidelines from Microsoft say to
do so, and that's what Paint does, at least), and add an "All Capture
Files" entry with all the file extensions for the file types we support
(it'll pick up all text files, but there's not much we can do about
that, and it won't pick up files with *no* extension or weird
extensions, such as you might get from UN*X systems or from WinDump
commands, but at least it'll filter out some other crud).
Fix what appear to be memory leaks; that should be backported unless
I've missed something and they aren't leaks.
Fix an out-of-date comment, and add an additional comment.

with the checksum computed differently in some fashion, or perhaps just
being computed incorrectly), not compressed *DOS* Sniffer files (which
use their own form of compression, which doesn't compress the entire

Floating-point constants are double by default; you have to add "f" to

This was the 4th patch, but also:
- use gmalloc0() to allocate vwr struct. Otherwise, valgrind says that
many of fields were still uninitialised when parse_s1_W_stats later
read them
- whitespace tidyup, got rid of remaining tabs and trailing whitespace
Did a fair bit of fuzz-testing without seeing any problems.

If no target OS version was specified, default to the major version on

argument to the -F flag for pcap format is "libpcap", not "pcap", we

to support using "libpcap" as well.
Update the man pages to refer to it as pcap as well, and fix the
capitalization of "WinPcap" (see http://www.winpcap.org) while we're at
it.
Also, refer to http://www.tcpdump.org/linktypes.html for the list of

This lets more of the libwiretap code be common between the read and
seek-read code paths, and also allows for more flexibility in the "fill
