Hello everyone,

use to hook a system call in module without modify the

Thanks for reply.
I also asked that set_user_nice where and when is called(file and line).
I think it is not called after each forking operation, isn't it? Could you
give calling order between functions from

Hi,
Thank all of you for helping me with problem!
I don't want to modify my kernel source so I am trying to learn to use LSM
security hook even though it seems that it couldn't hook all the system
calls, I think it should be enough for me.
Thanks again!

Hi,
I have tried the LSM framework,but when I make my module , I got
waining:'register_security' undefined, then I check security/security.c
and found out that register_security is not exported ! So if I want to use
this function ,I must hack kernel by exporting and recompiling kernel which

i figure someone here has probably done this -- just as
proof-of-concept, i want to create a kernel that incorporates a
standalone initramfs root filesystem. if it's useful to know, it will
be for a powerpc lite5200 board.
it's not something i'd do in normal practice, but it's for a course

Hi all,
When a protocol like TCP or UDP creates an sk_buff and passes it down
to the layer 3 and layer 2 protocol functions, which module has
ownership of the buffer as it gets passed down? Is it the
responsibility of the caller, or the callee to free the sk_buff? Are
there any exceptions?
