https://bugzilla.novell.com/show_bug.cgi?id=409504 Summary: kernel attempts to write on a DVD, which contains an encrypted reiserfs image. Product: openSUSE 10.3 Version: Final Platform: i686 OS/Version: openSUSE 10.3 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: robin.listas@telefonica.net QAContact: kernel-maintainers@forge.provo.novell.com Found By: --- While investigating Bug 345039, I discovered this little problem: I mount a DVD (/dev/hdc), which contains an LUKS encrypted reiserfs filesystem (details at the end). It is of course not writable, but the kernel attempts to write to it - or so it seems to me: Jul 16 12:24:29 nimrodel kernel: REISERFS (device dm-6): found reiserfs format "3.6" with standard journal Jul 16 12:24:29 nimrodel kernel: REISERFS (device dm-6): using ordered data mode Jul 16 12:24:29 nimrodel kernel: reiserfs: using flush barriers Jul 16 12:24:29 nimrodel kernel: REISERFS (device dm-6): journal params: device dm-6, size 8192, journal first block 18, max trans len 1024, max batch 900, max commit age 30, max trans age 30 Jul 16 12:24:29 nimrodel kernel: REISERFS (device dm-6): checking transaction log (dm-6) Jul 16 12:24:29 nimrodel kernel: reiserfs: disabling flush barriers on dm-6 Jul 16 12:24:30 nimrodel kernel: REISERFS (device dm-6): Using r5 hash to sort names Jul 16 12:25:03 nimrodel kernel: hdc: command error: status=0x51 { DriveReady SeekComplete Error } Jul 16 12:25:03 nimrodel kernel: hdc: command error: error=0x50 { LastFailedSense=0x05 } Jul 16 12:25:03 nimrodel kernel: ide: failed opcode was: unknown Jul 16 12:25:03 nimrodel kernel: ATAPI device hdc: Jul 16 12:25:03 nimrodel kernel: Error: Illegal request -- (Sense key=0x05) Jul 16 12:25:03 nimrodel kernel: Invalid field in command packet -- (asc=0x24, ascq=0x00) Jul 16 12:25:03 nimrodel kernel: The failed "Write 10" packet command was: Jul 16 12:25:03 nimrodel kernel: "2a 00 00 00 41 26 00 00 02 00 00 00 00 00 00 00 " Jul 16 12:25:03 nimrodel kernel: end_request: I/O error, dev hdc, sector 66712 Jul 16 12:25:03 nimrodel kernel: Buffer I/O error on device hdc, logical block 8339 Jul 16 12:25:03 nimrodel kernel: lost page write due to I/O error on hdc Mount command: nimrodel:~ # /etc/init.d/boot.crypto start /dev/dvd.l Please enter passphrase for /dev/dvd.l (mycrypt_mm_dvd): Please enter passphrase for /dev/dvd.l (mycrypt_mm_dvd): key slot 0 unlocked.
