Yuan Chen e32a996582 libbpf: Fix null pointer dereference in btf_dump__free on allocation failure ... [ Upstream commit aa485e8789 ] 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.
