I've written a dm-crypt patch some weeks ago that does what you describe. The crypto information (cipher and key) is added to a keyring and then the device is constructed using a reference to this key. I had some issues with the keyring code (mainly a deadlock problem with crypto module autoloading): http://lkml.org/lkml/2005/2/4/113 I would also like to switch dm-crypt to acrypto once it's accepted into the kernel. --=-H0wXgYv5Qcf8Fpp1/6+t Content-Type: application/pgp-signature; name=signature.asc Content-Description: Dies ist ein digital signierter Nachrichtenteil -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQBCMEC5ZCYBcts5dM0RAnkJAJ93ViuWshfAJo6SQoqalNcP0OywFgCdH2bd 51GZcAvpj384hZJHe2pxmDE= =LoSh -----END PGP SIGNATURE----- --=-H0wXgYv5Qcf8Fpp1/6+t-- - 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/
