AFAIK, the main issue is: If I write some data to the start of block N, I get a bit pattern. If I write the same data *anywhere* else (the middle of block N, the start of block M != N, a different on-disk bit pattern must result. If there are identical bit patterns, then the system is vulnerable. Obviously, this vulnerability doesn't depend on whether you're using cryptoloop or dm-crypt. -- Matthias Urlichs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
