Hi
Assuming to have this struct:
struct hash_elem {
int cnt;
};
and kernel space program want read cnt value:
struct hash_elem *val = bpf_map_lookup_elem(&hash_map, &key);
if (val)
{
# time fraction
bpf_printk("My value %d", val->cnt);
}
What happens if the hash_map is a pinned map and in the same time
space of 'time fraction" a user program deletes the element of the
key?
What happen at val pointer?
Thanks.
Marco
