This I believe incorrect. Please cite caselaw if you know better. > With UIO, you have a kernel module that is so small, that even somebody who > hasn't got the hardware can easily review it and tell if the code is OK or > not. > It is easy to maintain and doesn't reveal any secrets about the hardware. False Because you have no idea if the interface is correct or the userspace is doing stuff like triggering DMA to arbitary addresses via the interface or mmap functions. If it does so then even if its root only you've blown your security model. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
