Re: linked list within a kernel probe

static __u8 _kprobe_setup_cache_elements( struct kprobe_head *pHead, __u16 elements, __u32 size) {

…

struct list_head local_head;

INIT_LIST_HEAD(&local_head);

…

pHead->p_mem_cache = &local_head;

…

}

just from a quick look at this code, my guess is that you should not be using stack addresses in your list. Your local_head is on the stack, therefore it gets corrupted after you exit your function and invoke other functions. Did you really mean to store a pointer to local_head, or was your intention to point to the first element on local_head?
