Bug 461322

*** Bug 461342 has been marked as a duplicate of this bug. ***

OK, vlc has a problem with libdvdread, should be fixed next hours.

But also all other player couldn't play a video dvd or an audio cd because of bad rights:

Before inserting a video dvd:

detlef@detlef-pc:~> getfacl /dev/sr0 
getfacl: Removing leading '/' from absolute path names
# file: dev/sr0
# owner: root
# group: disk
user::rw-
user:detlef:rw-
group::rw-
mask::rw-
other::---

After inserting a video dvd:

detlef@detlef-pc:~> getfacl /dev/sr0 
getfacl: Removing leading '/' from absolute path names
# file: dev/sr0
# owner: root
# group: disk
user::rw-
group::rw-
mask::rw-
other::---

The "user:detlef:rw-" are deletet every time i put in a video/audio-cd/dvd.

set /dev/sr0 permissions to 0666 or add the user detlef to the group
'disk' and thre permission problem should be solved.

I know, but that's only a workaround, not fixing the problem...

Sorry for me it didn't work to change the rights as proposed and to add the user to the disk group. Only as root playing audio CDs and video DVDs is possible. It seems that a more basic permission problem is present as on opensuse 11.1. Also problems mounting usb-sticks are present (no permession to read them or to write on them). Is there a bugfix in sight?

Did the trick:

# hal-device '/org/freedesktop/Hal/devices/volume_label_DVDVolume' | grep info.capabilities
  info.capabilities = { 'volume.disc', 'volume', 'block', 'access_control' } (string list)

OK, search for a match in hal policy:

/usr/share/hal/fdi/policy/10osvendor/20-acl-management.fdi:

    <!-- Removable block devices -->
    <match key="info.capabilities" contains="block">
      <match key="@block.storage_device:storage.removable" bool="true">
        <append key="info.capabilities" type="strlist">access_control</append>
        <merge key="access_control.file" type="copy_property">block.device</merge>
        <merge key="access_control.type" type="string">removable-block</merge>
      </match>
    </match>


Match!

/usr/share/PolicyKit/policy/org.freedesktop.hal.device-access.policy:

 <action id="org.freedesktop.hal.device-access.removable-block">
    <description>Directly access removable block devices</description>
    <message>System policy prevents access to removable block devices</message>
    <defaults>
      <allow_inactive>no</allow_inactive>
      <allow_active>no</allow_active>
    </defaults>
  </action>

Bingo! :(

allow_active -> no

Add Danny to CC

Danny, should we have an extra rule for optical dvd, or only change removable block devices to yes?

Detlef

Sorry I#m not an experienced linux user an d could not entirely follow the steps above. I tried to change /usr/..............<allow_inactive>no</allow_inactive>
      <allow_active>no</allow_active>
    </defaults>
  </action>  allow_active to yes
but still get for all removable devices (cd, dvd, usb-ticks etc.) the warning "no such fie or folder. The device doesn't exist". What can I do alternatively?

Same problem: changed the device permissions, but still no DVD-toaster is found - only a normal DVD drive

I am not very familiar with HAL/PolicyKit, but strangely enough there seems to be such a rule (directly above the rule quoted by Detlef Reichelt in Nr. 7)

/usr/share/PolicyKit/policy/org.freedesktop.hal.device-access.policy:

  <action id="org.freedesktop.hal.device-access.cdrom">
    <description>Directly access optical drives</description>
    <message>System policy prevents access to optical drives</message>
    <defaults>
      <allow_inactive>yes</allow_inactive>
      <allow_active>yes</allow_active>
    </defaults>
  </action>

The first part seems to work fine 

      <allow_inactive>yes</allow_inactive>

as seen by getfacl /dev/sr0 without a medium inside the drive, but the second part 

      <allow_active>yes</allow_active>

seems to be ignored/overridden by the above mentioned rule 

/usr/share/PolicyKit/policy/org.freedesktop.hal.device-access.policy:

 <action id="org.freedesktop.hal.device-access.removable-block">
    <description>Directly access removable block devices</description>
    <message>System policy prevents access to removable block devices</message>
    <defaults>
      <allow_inactive>no</allow_inactive>
      <allow_active>no</allow_active>
    </defaults>
  </action>

Curiousely, but for me, in the end a simple
chmod -R 777 /media 
solved all the problems: VideoDVDs are recognized, and all removable devices are mounted and displayed as /media/... correctly now!? Whatever happened before...
