First bug: The Network Instruments Observer file format abbreviation is
incorrect. It is "niobserverv" instead of "niobserver", which is probably a
vestige from 1.4 when the abbreviation was "niobserverv9".
Second bug: The packet header magic number field is correctly swapped the first
time when reading the entire packet header. It is incorrectly swapped yet again
when reporting an invalid value. Both swaps use GUINT_FROM_LE, which is a no-op
on little-endian platforms. But the error message that is displayed to users of
big-endian platforms will contain a byte-reversed value.

This patch incorporates the following fixes from the patch attached to
bug 5671 with changes as noted below:
1.) Files where the packet header and packet data are noncontiguous are
handled improperly, resulting in read misalignment and ultimately the
error message, "Observer: bad record: Invalid magic number 0xXXXXXXXX."
This bug is caused by not obeying the packet_entry_header.offset_to_frame
field.
2.) Daylight savings time is not properly accounted for in files using
local time encoding.
3.) As of Observer/GigaStor v13.10 (bug 5671 incorrectly stated v14),
timestamps in the file format changed from local time encoding to GMT
encoding. Wiretap has been changed to support reading both formats.
Patch submitted with bug 5671 added a separate file type to allow
writing local format. This patch does not add the separate file type
and always writes GMT.
4.) The wtap_dumper.bytes_dumped field is not being properly incremented
as data is written to files.
This patch also incorporates the following additional enhancements /
fixes not in bug 5671:
1.) Support for reading BFR files which contain Fibre Channel captures.
Test file Fibre_Channel_Capture.bfr attached.
2.) Support for modified file header used in upcoming v15. New header
file format takes an unused byte from the version string to allow for a
larger offset to the first packet to be specified. Test file
V15_Lrg_Hdr_Test.bfr is attached, it is also a fuzz test as the number
of TLV items given in the header is less then the actual.
3.) It was found that if the number of TLV items given in the header was
larger then present it would fail to open the file. Test file
V9_Num_TLVs_Too_Big.bfr is attached.

zran.c example in the zlib source.
This means that problems in the file's contents might not be reported
when a packet is read, as long as there's no problem in the contents of
the file up to the last bit of compressed data for the packet; we now
check for errors after finishing the sequential read of the file, at
least in some programs, so that shouldn't be an issue (the other
programs need to be changed to do so as well). This is necessary in
order to be able to read all the packets we saw in the sequential pass;
it also lets us get a few more packets from truncated files in some
cases.

Boolean in the file format table to "writing requires seeking", give all

Added support for Symbian OS btsnoop.
The bluetooth HCI layer in Symbian OS can be configured to log all packets to a
file. The log format, "btsnoop" is based on the RFC1761 "snoop" format - but
differences in the header make it incompatible.
The btsnoop format supports logging of these formats:
"H1" (raw HCI packets without framing)
"H4" (HCI UART packets including packet type header)
"H5" (HCI 3 wire UART packets including framing)
"BCSP" (HCI bluecore serial protocol including framing)
"H1" and "H4" are section numbers in the original v1 bluetooth specifications,
but still used colloquially - wireshark's existing support for Linux bluez HCI
logs uses the "H4" name.
In practice, the "H1" format is used for H5,BCSP and USB HCI logs, as the HCI
packet logs are mainly useful for debugging higher layers, bluetooth profiles
and bluetooth applications.
From me:
Deleted some unused prototypes.
Mark an unused parameter.

It takes a text-dump op the captured packets and parses the headers

function of the Juniper NetScreen firewalls.

The code for reading ERF files has not been significantly
updated since 2004. This patch brings it up to date with a
number of changes.
1) Increase number of decodable ERF types from 7 to 12. This
covers newer DAG card models and firmware updates.
2) Fix timestamp conversion. Was calculating only microsecond
precision, now displaying with nanosecond resolution. Hardware
precision is 7.5 to 30 ns depending on model.
3) Allow the user to specify HDLC encapsulation as 'chdlc',
'ppp_serial', 'frelay' or 'mtp2'. This is needed because the
ERF HDLC capture formats do not include information on what
protocol is used at the next level. This is currently done via
an environment variable 'ERF_HDLC_ENCAP' and is analagous to the
existing 'ERF_ATM_ENCAP' variable.
If the user does not specify an HDLC encapsulation it tries to
guess, and falls back to MTP2 for backwards compatibility with
Florent's existing behaviour.
I know environment variables are ugly, suggestions are welcome.
4) When reading HDLC captures as MTP2, use
WTAP_ENCAP_MTP2_WITH_PHDR rather than WTAP_ENCAP_MTP2. This
allows us to put the 'Multi-Channel ERF' record 'channel
number' field into the MTP2 pseudo header > 'link_number'
field. This is then displayed in Frame information, and can
be filtered on. (Would be nice if it could be made a display
column?)
Because the ERF record does not specify whether Annex A is used
or not, we pass MTP2_ANNEX_A_USED_UNKNOWN and allow the existing
user preference to decide.
Move the MTP2_ANNEX_A_ definitions into Wiretap, make the annex_a_used
field a guint8, and change MTP2_ANNEX_A_USED_UNKNOWN to 2 so it fits in
a guint8. (This means that if you can save an ERF MTP2 file as a
libpcap file, the pseudo-header will have MTP2_ANNEX_A_USED_UNKNOWN in
it.)

This patch consists also the last issues. Additionally it solves:
- For the SSCOP frames the AAL5 decoding was not performed due to an earlier patch. This caused that no SSCOP message was properly decoded.
- As the detection between a LANE frame and a SSCOP frame is rather hard a switch within the atm dissector is included which enforce SSCOP dissecting over a LANE frame. At the moment I do not see a better solution for that.

patch and new files provide support for Catapult DCT2000
.out files to wiretap and ethereal.
This wiretap support (catapult_dct2000.c+h) appends a short header to
each packet giving some context, and a corresponding ethereal dissector
(packet-catapult-dct2000.c) parses this before passing the real payload
onto an existing ethereal dissector (for ethernet, ip, lapd, ppp,
frame-relay,...).
For now, there is only support for saving dct2000 files in their own
format, although I may add support for converting between dct2000 and
libpcap later.
updated version of these files and patch, now with support
for MTP2. Olivier's trace used the ANSI variant - the MTP2 and MTP3
decode fine with the right preferences set (although the ISUP dissector
reports a reserved/retired message type).

currently limited to Ethereal and all the variants of libpcap filetypes only.
We might want to add output compression support to the other tools as well (tethereal, mergecap, ...).
We might also want to add support for the other filetypes, but this is only possible if the filetype functions doesn't use special output operations like fseek.
One bug is still left: if the input and output filetypes while saving are the same, Ethereal currently optimizes this by simply copy the binary file instead of using wiretap (so it will be faster but it will ignore the compress setting).
Don't know a good workaround for this, as I don't know a way to find out if the input file is currently compressed or not. One idea might be to use a heuristic on the filesize (compared to the packet size summmary). Another workaround I see is to remove this optimization, which is of course not the way I like to do it ...

I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ...
What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere.
As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon.
Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way...
As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number...
