Wireshark-bugs: [Wireshark-bugs] [Bug 8348] New: Incomplete dump of smb.file_data

Date: Sun, 17 Feb 2013 16:02:34 +0000
Bug ID 8348
Summary Incomplete dump of smb.file_data
Classification Unclassified
Product Wireshark
Version 1.8.2
Hardware x86
OS All
Status UNCONFIRMED
Severity Major
Priority Low
Component TShark

Build Information:
Vanilla Debian tshark package
--
I'm working with smb protocol invoking tshark with this cmdline:

tshark -r pcapfile -T fields -e smb.file -e smb.fid -e 
smb.file.rw.length -e smb.file.rw.offset -e smb.file_data -R smb.file_data

And here's the problem. smb.file_data is incomplete, it seems to top up 
as a string of 65535 bytes (with colons) which is 21845 B of real data.
If a SMB packet is bigger than that it gets truncated.

Eg:
smb.file.rw.offset 0
smb.file.rw.length 61440
smb.file_data

As you can see the line ends with a colon, like if truncated.

Thanks.
