Hi,
>what is
exactly what you wanna do ? do you wanna know the returned value by a system
call that a certain process or user does by means of an LKM ? i.e do you wanna
make an LKM that hooks the return values of a syscalls ?
I have a LKM which overrides a syscall,
now I want to get the error no returned by the orginal
syscall.
(For example: In AIX seterror() and geterror()
kernel fuctions set the error no in the error no table and reads the
table
for the appropriate error returned by the call) I
want a similar mechanism in linux.
Hope things are clear to you now.
Thanks,
Saumendra
