Music/Audio CDROMs, DVDs, & Etch kernel Security Update.
The following is a record of a problem we had here with a debian Etch Security
Update that we performed on 26 Aug. 2008. It has now been resolved.
The culprit seems to have been the
linux-image-2.6.18-5-686_2.6.18.dfsg.1-13etch6_i386.deb kernel
package. However, there seems to be no maintainer for this or related
packages. http://packages.debian.org/etch/linux-image-2.6.18-5-686 leads to a
set of "No maintainer for linux-image-2.6.18-5-686" pages!
Hence, if anyone has a better idea of where this bug report may be submitted,
the info would be appreciated.
Thanks,
DB
P.S. The following is posted as an FYI, only, because it may be of use to
anyone else seeing similar symptoms. Otherwise, it may be ignored.
Problem Description:
Subsequent to the aforementioned Security Update, Audio CDROMs could no longer
be played, and almost no utility could read their contents. Also, vlc could no
longer play encrypted DVDs.
Work-around:
After extensive tests, we went with our original hunch that the
common denominator to the two problems was in the kernel.
We installed a recent kernel. This was a generic build which used the
configuration of the Security Update's running kernel.
The rest of the Security Update was kept. Manual reversion of vlc (to the
pre-Update versions) had not helped. Other vlc libraries had remained
unchanged.
Before:
Debian Etch stable
linux-image-2.6.18-5-686 2.6.18.dfsg.1-13 kernel
libvlc0 0.8.6-svn20061012.debian-5etch1
vlc 0.8.6-svn20061012.debian-5etch1
vlc-nox 0.8.6-svn20061012.debian-5etch1
After:
Debian Etch stable with the Security Update
linux-image-2.6.18-5-686_2.6.18.dfsg.1-13etch6_i386.deb
libvlc0_0.8.6-svn20061012.debian-5.1+etch2_i386.deb
vlc_0.8.6-svn20061012.debian-5.1+etch2_i386.deb
vlc-nox_0.8.6-svn20061012.debian-5.1+etch2_i386.deb
Some of the various attempts and error messages are presented here so that they
may be found by people tackling the same problem :
- The CDROM/DVD drive is region-free. regionset did not help.
- IIRC cdda2ogg was the only utility which managed to rip audio tracks. grip
failed completely, and could not play them, either.
- 'icedax -v toc -D /dev/cdrom' (ie the debian fork of cdda2wav) resulted in

- Note that the new vlc, installed by the Security Update, may have overwritten
the default DVD device path. That is unlikely, but we had to re-enter the
"/dev/dvd" again.
- The following is a typical example of vlc's crash. Note that the copy-control
protection is RCE, but it always handled it prior to the upgrade.

- dvd+rw-mediainfo was used at some point.
- The new kernel resulted in grip seeing, playing and ripping the audio
CDROM. (rhythmbox doesn't work, IIRC.) cdplay, xmcd, dcd, sound-juicer, xine,
vlc all work.
- The RCE encrypted DVD now plays with vlc. (Again, personal info has been
snipped.)
