[PATCH] pktcdvd: Fix overflow for discs with large packets
The pktcdvd driver was using an 8 bit field to store the packet length
obtained from the disc track info. This causes it to overflow packet length
values of 128KB or more. I changed the field to 32 bits to fix this.
The pktcdvd driver defaulted to its maximum allowed packet length when it
detected a 0 in the track info field. I changed this to fail the operation
and refuse to access the media. This seems more sane than attempting to
access it with a value that almost certainly will not work.
