Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bpf: Check rcu_read_lock_trace_held() in bpf_map_lookup_percpu_elem()<br /> <br /> bpf_map_lookup_percpu_elem() helper is also available for sleepable bpf<br /> program. When BPF JIT is disabled or under 32-bit host,<br /> bpf_map_lookup_percpu_elem() will not be inlined. Using it in a<br /> sleepable bpf program will trigger the warning in<br /> bpf_map_lookup_percpu_elem(), because the bpf program only holds<br /> rcu_read_lock_trace lock. Therefore, add the missed check.
