| H A D | augmented_raw_syscalls.bpf.c | diff 262b54b6c9396823ab06df46a1be475c44b28b5f Mon Aug 21 08:40:09 CDT 2023 Arnaldo Carvalho de Melo <acme@redhat.com> perf bpf augmented_raw_syscalls: Add an assert to make sure sizeof(saddr) is a power of two.
We're using the BPF verifier suggestion:
22: (85) call bpf_probe_read#4
R2 min value is negative, either use unsigned or 'var &= const'
That works only when const is a (power of two - 1) so add an assert to
make sure that that is the case.
