Analyze and fix the following issue in the Linux kernel code: [PATCH] pktcdvd: Fix overflow for discs with large packets
Problem Details: 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...
