bpf_probe_read_user returns error (-14) on Android 11, Kernel 4.14, ARM64

Hi folks,

I'm running BCC on Android 11, Kernel 4.14, ARM64 and `bpf_probe_read_user` returns an error (-14). As a result *opensnoop* returns an empty filename string.

I'm aware of #2253 and implemented the solution that supposedly should fix the issue (https://lkml.org/lkml/2019/5/2/1100) to no avail.

#3094 is somewhat related and the solution there looks to be similar to the above (i.e. adding `bpf_probe_read_user` from the later version).

Has anyone encountered something like that or knows how can I get more information about the issue?

Cheers,
Vadim
