bpf: Add missed newline in verifier verbose log
check_stack_access() that prints verbose log is used in adjust_ptr_min_max_vals() that prints its own verbose log and now they stick together, e.g.: variable stack access var_off=(0xfffffffffffffff0; 0x4) off=-16 size=1R2 stack pointer arithmetic goes out of range, prohibited for !root Add missing newline so that log is more readable: variable stack access var_off=(0xfffffffffffffff0; 0x4) off=-16 size=1 R2 stack pointer arithmetic goes out of range, prohibited for !root Fixes: f1174f77b50c ("bpf/verifier: rework value tracking") Signed-off-by: Andrey Ignatov <rdna@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
