Johannes Krude bf3043d277 bpf, offload: Replace bitwise AND by logical AND in bpf_prog_offload_info_fill ... commit e20d3a055a upstream. This if guards whether user-space wants a copy of the offload-jited bytecode and whether this bytecode exists. By erroneously doing a bitwise AND instead of a logical AND on user- and kernel-space buffer-size can lead to no data being copied to user-space especially when user-space size is a power of two and bigger then the kernel-space buffer.
