We are trying to test a function using BPF trampoline with fexit but it's failing because the kernel func is optimized and it seems the BTF entry doesn't exist for that function.
Do you know if there is a way to work with this without compile the kernel?
OS : Ubuntu 20.04
Kernel: 5.15
error attaching bpf program: loading objects: field TcpAckUpdateRtt: program tcp_ack_update_rtt: attach Tracing/TraceFExit: find target for fexit tcp_ack_update_rtt: find target in modules: iterate modules: get next BTF ID: operation not permitted
Similar but with kprobe: iovisor/bcc#1963
