Hi Folks, I need to encrypt a jffs2/mtd formatted flash filesystem for an embedded device, Normally using a loopback interface (cryptoloop, DM-crypt or loop-aes) solves this problem but they are not well known on journalling file systems (like jffs2) because of cached write etc.. Also I could'nt find any guideline for encrypting fikesystem on a flash. There is an ugly workaround to overcome this problem, I have placed an encrypted ext2 filesystem image on an normal jffs2 partition and mount this encrypted partition on a loopback, but this is not secure, consumes alot for disk space and not reliable (is'nt it?) Is there any other way to encrypt an jjffs2 partition, if not, what do you think about my ugly workaround? Thank alot Emin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
