[Fault-injection-developer] Kernel version - network driver

[Sripriya N. <sri...@np...>]

Hi,
    I am currently involved in developing network driver for gigabit =
ethernet card under Linux. I would like to test the driver I develop =
with the "Fault injection test harness" that comes as a patch for Kernel =
2.5. Now my question is, what kernel version would be advisable to write =
the driver on? Is it too much of a porting work if I develop on the =
kernel 2.4 which is reasonably stable, to finally test with the =
hardening tool.or will it be a risk developing on kernel 2.5 development =
series? I would also like to know the amount of work involved in porting =
back the harness tool to kernel 2.4, if it is possible.
Kindly suggest the latest kernel version I can work on inorder to use =
the hardening tool.

Thanks
Sripriya

Dear Sripriya,
	Our kernel patch is based on the top of Linus' tree. If you would like
to develop driver with FITH, I suggest you download our development tree
by BK directly. I think 2.5 kernel is also reasonably stable because of
feature-frozen and much work on it.
	I don't see many changes in network driver model between 2.4 and 2.5
except trivial module mechanism. So it is easy to port driver
bi-directly.
	According to backport FITH to 2.4, making KMMIO/KIRQ work in 2.4 is
trivial, but DBP/DR are a little difficult because they need KPROBE.
