Hi everybody,

I am currently working with FreeBSD 4.1 on i386 platform on a 
pseudo-device driver that interacts with the networking subsystem in the 
kernel. Basically, we are intercepting both incoming and outgoing 
IP-level trafficfor specific processing. Obviously, there is also some 
administrative processingthat is conducted from a user-land daemon.

I have detected a problem with my driver occuring in the context of the 
network SWI, as shown by the following basic stack:

#14 in ... /* private code */
#15 in ip_input
#16 in ipintr

My problem comes from that I would like to get the stack frame of the 
interrupted execution process (everything that would be frame #17 and 
below) and I do not know how to do this with the GDB debugger.

Is there anybody how could provide me with the steps to achieve this ?

Regards,

X. Galleri
