[PATCH v2 bpf-next 1/3] libbpf: disassociate section handler on explicit bpf_program__set_type() call

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If user explicitly overrides programs's type with
bpf_program__set_type() API call, we need to disassociate whatever
SEC_DEF handler libbpf determined initially based on program's SEC()
definition, as it's not goind to be valid anymore and could lead to
crashes and/or confusing failures.
