make ndmp a heuristic dissector so it will "win" over tcp esp if the
packets look like ndmp and if "preferences/tcp/heuristic dissectors
first has been
chosen"

by enforcing that header fields have names of length > 0. This should fix
the display of those fields and also make them filterable (which was the
subject of the bug). Abbreviations are (still) optional: if they are empty
then the field is not filterable.
Update README.developer with this information.
Add header field names in several dissectors where they were missing.
In packet-arp.c give "packet-storm-detected" a name (as above) but also set it
as _GENERATED.
Also remove trailing white space from all the files checked in.

there are many reasons why some protocols actually need to be able to access the pinfo structure while determining the pdu size
svn path=/trunk/; revision=19751
this fixes a regression caused by the recent scsi data in/out reassembly code which made the scsi dissector fail to dissect data in/out over ndmp correctly if scsi reassembly was enabled
svn path=/trunk/; revision=19525
and also (if reassembly is disabled) only dissect the initial (offset==0) data pdu.
dissect_scsi_payload() does not yet use this parameter.
now that we have both data offset and expected data length/bidir expected data length and also the read/write flags availabe we have what we need to reassemble data in/out pdus (modulo overflow/underflow but those are so rare we can worry about them later).
ndmp: ndmp conceptually always has a data in and a data out phase and never fragment the data into smaller pdu's os that dissector always report offset as 0.

pass conversation form the transports up to the scsi layer
add tracking of conversation specific info to scsi osd
add tracking of conversation+lun specific info to scsi osd
for scsi osd add tracking of PARTITIONS and display in which frame they were created/removed
svn path=/trunk/; revision=19505
so that the two scsi transports FCP and ISCSI can provide the expected data transfer lengths to SCSI to allow SCSI reassembly.
NDMP does not really need these hints since for NDMP (and also iscsi-lite) there is conceptually always both data in and data out phases and there is never any fragmentation.

we used the wrong size which caused emem to complain that the canary value had been stomped upon.
another win for the canary feature. thanks gerald

everytime a ndmp_[scsi|tape]_open is seen create a new itl
we need an itl structure to be able to know what commandset a certain device is using.
svn path=/trunk/; revision=18490
we need this in order to be able to provide proper itlq structures to the scsi dissector so that response data from scsi is dissected properly.
svn path=/trunk/; revision=18104
rename the preference to DEFAULT protocol version to indicate it is only used for those conversation where we have not automatically detected the version used.
svn path=/trunk/; revision=18003
update the comment in packet-scsi.c to reflect that it is the transport now that is responsible to track itl and itlq data

structures for scsi.
we no longer need the scsi_task_id structure passed by pinfo->private_data so get rid of it.
we no longer need the (broken by design) scsi_task_data hash table since this has been replaced byt hte itl and itlq structures and tracking
svn path=/trunk/; revision=17952
remove the two fields opcode and devtype from the scsi_task_data structure since these are also part of the itlq and itl structures
svn path=/trunk/; revision=17949
and get rid of some breakage in the design
let the scsi transport keep track of itl (initiator, target, lun) matching
and let it pass a itl structure to scsi that is persistent across packets.
let scsi use this itl structure to track device type for a specific itl instead of the (must have been) broken hashtable.
update both iscsi and fc to track the itl structure for scsi and schange the scsi signature to accept itl as a parameter.
more to come.

this finally allows us to have scsi.time for scsi transactions but we need to cleanup and refactor the other three scsi entrypoints before we should implement scsi srt to make the other three also take an exchange data structure as parameter from their transports (and get rid of the pinfo->private_data )
svn path=/trunk/; revision=17838
while this should improve performance by unmeasurably little it does have the sideeffect that once we finish the rewrite tcp analysis might actually work and work well even for tcp over tcp tunnelling.
this also means that if you include packet-tcp.h you also need to include emem.h .

I've changed all settings I could find to TRUE. It might be reasonable to change some protocol settings back to FALSE, if reassembling fails very often.

directory to the epan directory. Some of them should perhaps ultimately
be moved to epan/dissectors, if they pertain only to stuff exported by a
particular dissector.
Fix Gerald's e-mail address in files we're moving.

also change bytes_left_to_read to be a INT64 and not a UINT64.
It iss supposed to be an UINT64 but some implementations are buggy and it is easier to make sense of this field one for those buggy clients if it is printed as an INT64.
This change/violation will not affect any correct/valid NDMP implementation or how ethereal decodes its output unless your entire backup is > 2**63 bytes in size.

on scsi.lun and prettify the summary line a bit.
ndmp still needs some work to track luns between commands
and fcp needs verification it works for volumesetaddressing.

1) Added a setup_frame parameter to conversation_t
2) Used the conversation_t next to maintain a list of conversations with the
same src/dest tuple but different setup_frame number.
3) Changed the signature of find_conversation() and conversation_new() to pass
in the frame number.
4) Adjusted packet-sdp to select RTP conversation if both m=audio and m=image
are present, and T.38 conversation if only m=image is present. I expect that
RTP/T.38 dissecting to be better, but I don't have a way to generate T.38
packets.

so that it will track pdu boundaries properly
not tracking pdu boundaries caused pain since it would miss too many
commands

I (hopefully) didn't changed any protocol fields or preference file names, but only the GUI labels appearing in the protocol display and the protocol preferences.
Also added a note to the protocol preferences (where appropriate), that you have to enable "Allow subdissectors to reassemble TCP streams" at the corresponding protocol settings for TCP reassembling to take effect.
If you encounter any mistakes I've made here, please let me know...
