used for the DOS-based ATM Sniffer. (That's not a great name, but I
couldn't think of a better one.)
Add a new WTAP_ENCAP_ATM_PDUS_UNTRUNCATED encapsulation type for capture
files where reassembled frames don't have trailers, such as the AAL5
trailer, chopped off. That's what at least some versions of the
Windows-based ATM Sniffer appear to have.
Map the ATM capture file type for NetXRay captures to
WTAP_ENCAP_ATM_PDUS_UNTRUNCATED, and put in stuff to fill in what we've
reverse-engineered, so far, for the pseudo-header; there's more that
needs to be done on it, e.g. getting the channel, AAL type, and traffic
type (or inferring them if they're not in the packet header).

We should accept both (perhaps bytes 2 and 3 are a version number ?)
- the code which looks for the "capture start time" is wrong.
Apparently, we should look for the string "Active Time" in the file.
The "frame_date" structure which contains the capture start time is
found 32 bytes before this string.

Surveyor capture, as there's one link-layer type that UNICOS/mp snoop

-Wcast-align" to be added to CFLAGS (except in Wiretap, where we already
do "-Wcast-qual"). We don't do them by default, as they produce some
warnings that aren't easy to eliminate; if we figure out how to
eliminate them on all platforms (or at least, on the platforms where you
*can't* eliminate them, reduce them to a low level), we can make those
options the default.

WTAP_ENCAP_ISDN encapsulation type, which includes a pseudo-header
giving the direction (user-to-network or network-to-user) and the
channel number.
Add a new circuit type, using the ISDN channel number as the circuit ID.
Add an ISDN dissector to put the direction and channel number into the
protocol tree and to call the appropriate dissector for the payload
based on the channel (LAPD for the D channel; V.120, PPP, or data for B
channels, based on some heuristics).

unknown bytes might actually be 32-bit fields.
The field after the upper 32 bits of the time stamp of the capture start
appears to be the speed of the network, in bits/second.
Put in a field for the rest of the file header, as a bunch of 32-bit
values (most fields are 32 bits, and all of them might be, in that
header), for use when reverse-engineering.
At least in version 002.x of NetXRay-format captures, WAN captures might
be ISDN captures; treat all WAN version 002.x captures as ISDN captures
for now, until we see some captures where that's wrong (and thus stand a
chance of figuring out where in the file header it indicates what type
of capture it is).

Allow "-" as the output file name in Wiretap, referring to the
standard error.
Optimize the capture loop.
Fix some of the error-message printing code in Ethereal and Tethereal.
Have Wiretap check whether it can seek on a file descriptor, and pass
the results of that test to the file-type-specific "open for output"

seek when writing the file return an error if seeks don't work.

offset of the beginning of the first record containing data from that
packet, and the offset from the first byte of data in that record of the
first byte of data from that packet; to read a given packet, seek to the
offset of the first record, and keep processing packets until we find
one with the right direction.
This fixes a problem where it wasn't correctly reading the packet, when
doing random access, in cases where you have a sequence of records that
stop in the middle of a packet.

DOCSIS support, including support for "Ethernet" captures where

the internal z_err value for the stream if an "fseek()" call it makes
fails, so that if "gzerror()" is subsequently called, it returns Z_OK
rather than an error.
To work around this, we pass "file_seek()" an "int *err", and have the
with-zlib version of "file_seek()" check, if "gzseek()" fails, whether
the return value of "file_error()" is 0 and, if so, have it return
"errno" instead.

Added support for NS_LS_TCP, NS_LS_UDP, NS_LS_LOOPBACK, NS_LS_ICMP and
unnamed subsystem 0xb9 (which contains ethernet headers in my captures frames).
However, NS_LS_ICMP will not be dissected since we dont have a
RAW_ICMP wiretap encapsulation type.

A little work still needs to be done on the new NCP dissector -- make

Note: I didn't merge in the PROTO_LENGTH_UNTIL_END macro... I wanted
to think about the various possible macros and review an email conversation
I had with Guy on the subject.

into Wiretap, so that if you read a frame from Wiretap you have what

just an image of the ATM Sniffer data. This means that Ethereal doesn't
have to know any ATM Sniffer-specific details (that's all hidden in
Wiretap), and allows us to add to that pseudo-header fields, traffic
types, etc. unknown to ATM Sniffers.
Have Wiretap map VPI 0/VCI 5 to the signalling AAL - for some capture
files, this might not be necessary, as they may mark all signalling
traffic as such, but, on other platforms, we don't know the AAL, so we
assume AAL5 except for 0/5 traffic. Doing it in Wiretap lets us hide
those details from Ethereal (and lets Ethereal interpret 0/5 traffic as
non-signalling traffic, in case that happens to be what it is).
We may know that traffic is LANE, but not whether it's LE Control or
emulated 802.3/802.5; handle that case.

"struct x25_phdr" to "wiretap/wtap.h".
Have two X.25 dissectors, one of which assumes that there's a "struct
x25_phdr" pseudo-header and one of which doesn't; the former uses the
information in that pseudo-header to determine whether the packet is
DTE->DCE or DCE->DTE, and the latter assumes it has no clue whether the
packet is DTE->DCE or DCE->TDE. Use the former one in the LAPB
dissector, and the latter one in the XOT dissector and in the LLC
dissector table.
In the X.25-over-TCP dissector, handle multiple X.25 packets per TCP
segment, and handle X.25 packets split across TCP segments.
