Hi guys, I've got this problem and maybe you can give me an hint.
My goal is, given a thread leader process task_struct, walk deeper in
its childs and grandsons task_struct in order to count out how many
times fork has been called out. I'm trying to do this in order to detect
a fork bombing attack.
This is the code I wrote. The problem is that after insmod it,
ndiswrapper (used for mi wifi dongle) starts oops when trying to access
network. After removing my code, ndiswrapper was still oopsing. I don't
think it a ndiswrapper related issue because it happens just after I've
introduced the following routine in task_create LSM hook.
Am I missing something? :(
int __angel_count_spawned_process(struct list_head *list)
{
struct list_head *p;
if (list_empty(list))
return 0;
list_for_each(p, list)
return 1 + __angel_count_spawned_process((struct list_head *)&((struct
task_struct *)p)->children);
}
Thanks a lot
sp0nge
