RE: [Fault-injection-developer] How is the patched insmod making module_list available

[Wang, S. <sta...@in...>]

I've been totally confused.
As I know, the fith_insmod depends on fith_dm, and fith_dm depends on =
all
interceptors (includeing fith_fakeirq).
So fith_insmod will return an error unless all FITH's modules have been
loaded into kernel.
Can you give me more information about the error you encounted, Rusty?

Thanks :)
Stanley

Actually, it's fakeirq.o, not fith_fakeirq.  (hmm... maybe the=20
build script that I tossed out the window is moving fakeirq.o=20
to fith_fakeirq.o? It doesn't matter... I'm just getting a feel
for the code.)

* NOTE: Keep in mind I hacked out the need for the symbols your
        kernel patch was depending on.

[rusty@penguin2 rusty]$ sudo /sbin/insmod fakeirq
Using
/lib/modules/2.5.44-ac2/kernel/drivers/faultinjection/fakeirq/fakeirq.o
/lib/modules/2.5.44-ac2/kernel/drivers/faultinjection/fakeirq/fakeirq.o:=

unresolved symbol module_list

I can add all kinds of unresolved symbols to a module and fith_insmod=20
is happy to install the module.

Rusty,
	Did you mean you can not insert fith_fakeirq by normal insmod?
