…failure When btf_dump__new() fails to allocate memory for the internal hashmap (btf_dump->type_names), it returns an error code. However, the cleanup function btf_dump__free() does not check if btf_dump->type_names is NULL before attempting to free it. This leads to a null pointer dereference when btf_dump__free() is called on a btf_dump object. Fix: 351131b ("libbpf: add btf_dump API for BTF-to-C conversion") Signed-off-by: chenyuan <[email protected]>
