[Winpcap-bugs] PacketGetAdapterNames: The data area passed to asystem call is too small. (122)

[Greg Lee]

Certainly.  See attached files and report below.
 
1) First run windump -D with original packet.dll so that we verify the
problem still exists.
 
C:\Tools>windump -D
windump: PacketGetAdapterNames: The data area passed to a system call is too
small. (122)
 
2) Install debug packet.dll.
 
C:\Tools>ren packet.dll.2 packet.dll
 
3) Run windump -D with debug packet.dll.  Note that it works.
 
C:\Tools>windump -D
1.\Device\NPF_GenericDialupAdapter (Adapter for generic dialup and VPN
capture)
2.\Device\NPF_{4D1FBA71-F291-4653-8CEA-01D3FC82EFB6} ()
3.\Device\NPF_{7B4E25C5-963C-471E-8B6B-B188E034C227} (VMware Virtual
Ethernet Adapter)
4.\Device\NPF_{58E6FD8F-A6F8-457F-9F63-1989590EAEB3} (Dell Wireless 1470
Dual Band WLAN Mini-PCI Card (Microsoft's Packet Scheduler) )
5.\Device\NPF_{241D540D-9299-41FD-981F-DAD3E3552EF9} (VMware Virtual
Ethernet Adapter)
6.\Device\NPF_{71265B32-427A-438C-BEC1-434867A4156B} (Broadcom NetXtreme
Gigabit Ethernet Driver (Microsoft's Packet Scheduler) )

3) Verify the versions are as reported below.
 
C:\Tools>windump -V
windump version 3.9.5, based on tcpdump version 3.9.5
WinPcap version 4.0.1 (packet.dll version 4.0.0.901), based on libpcap
version 0.9.5
Usage: windump [-aAdDeflLnNOpqRStuUvxX] [ -B size ] [-c count] [ -C
file_size ]
                [ -E algo:secret ] [ -F file ] [ -i interface ] [ -M secret
]
                [ -r file ] [ -s snaplen ] [ -T type ] [ -w file ]
                [ -W filecount ] [ -y datalinktype ] [ -Z user ]
                [ expression ]

I am getting the following message from both WinDump and WireShark.  This
appears to be a WinPcap problem.  I am running Windows XP SP2.  WireShark
was running fine about 2 weeks ago, now I'm seeing this error message the
_second_ (and successive) time I perform a capture.  The first time I run
the capture everything works fine.
 
C:\>windump -D
windump: PacketGetAdapterNames: The data area passed to a system call is too
small. (122)
 
C:\>windump -V
windump version 3.9.5, based on tcpdump version 3.9.5
WinPcap version 4.0.1 (packet.dll version 4.0.0.901), based on libpcap
version 0.9.5

Suggestions for how to diagnose this problem?
 
Greg
