To: linux-kernel@vger.kernel.org Subject: ext3 on encrypted device mapper Message-Id: <20041202181727.5B50011643@mail.cypherpunks.to> Date: Thu, 2 Dec 2004 19:17:27 +0100 (CET) Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, i'm using a linux debian sarge on an encrypted root filesystem with linux 2.6.10-rc2 kernel. Filesystem is encrypted using dmcrypt, the encryption framework working on top of the device mapper. I deleted a file and immediatelly i attempted to recover it using debugfs. Linux aaa 2.6.10-rc2 #1 Wed Dec 1 09:52:37 CET 2004 i686 GNU/Linux aaa:~# df -k . Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/rootfs 8676440 5278584 2957108 65% / aaa:~# debugfs /dev/mapper/rootfs debugfs 1.35 (28-Feb-2004) debugfs: lsdel aaa:~# strings /dev/mapper/rootfs strings: Warning: '/dev/mapper/rootfs' is not an ordinary file Unfortunatelly neither with debugfs neither with a rogue strings i can access data on the encrypted filesystem. I think that device mapper should be modified to allow debugfs checking and to allow access on it like a tradional hard drive. Regards --aaa
