[dm-devel] Fw: [Bugme-new] [Bug 4507] New: device-mapper crypt can't encrypt cdrom device



I'm not sure if this is a bug or a user error.  Could someone please
update the bugzilla record?

Thanks.

           Summary: device-mapper crypt can't encrypt cdrom device
    Kernel Version: 2.6.11
            Status: NEW
          Severity: normal
             Owner: thornber sistina com
         Submitter: hadmut danisch de


Distribution: Debian 
Hardware Environment: Plain PC
Software Environment: dmsetup 1.01

Problem Description:

I tried to generate an encrypted CDROM (generated a 
plain ISO image, encrypted it with the device mapper, 
and burned it onto a CDROM).

But mounting the device with the device mapper fails:

# dmsetup create cdromx
0 73246 crypt aes-plain 61a60170273e74a5be90355ffe8e86ad 0 /dev/cdroms/cdrom0 0
device-mapper ioctl cmd 9 failed: Invalid argument
Command failed


dmesg says:
device-mapper: crypt: Device lookup failed

It seems as if dm_get_device in dm-table.c does not find the 
cdrom drive. Even giving the full device path 
/dev/ide/host0/bus1/target0/lun0/cd or the major:minor as 
22:0 does not help.


regards
Hadmut
