Leo Yan ef5b204336 bpf, libbpf, smatch: Fix potential NULL pointer dereference ... [ Upstream commit 33bae185f7 ] Based on the following report from Smatch, fix the potential NULL pointer dereference check: tools/lib/bpf/libbpf.c:3493 bpf_prog_load_xattr() warn: variable dereferenced before check 'attr' (see line 3483) 3479 int bpf_prog_load_xattr(const struct bpf_prog_load_attr *attr, 3480 struct bpf_object **pobj, int *prog_fd) 3481 { 3482 struct bpf_object_open_attr open_attr = { 3483 .file = attr->file, 3484 .prog_type = attr->prog_type, ^^^^^^ 3485 }; At the head of function, it directly access 'attr' without checking if it's NULL pointer. This patch moves the values assignment after validating 'attr' and 'attr->file'.
