Description

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