What do you mean by "zero"? The pointer itself can clearly never be NULL. The contents, now, that's a more interesting question. I believe it can never be all zeroes, since association request frames are not encrypted/protected and thus at least one byte in here must be non-zero. The MAC addresses are also very likely non-zero, but technically 00:00:00:00:00:00 is a valid MAC address I believe. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
