Thank you for the feedback. I remember the old dd bug. I'll review the code and check what's diverged from the original dd code. For the DA-09 test, I need to find a disk or a way to inject faulty sector in a raw image. |
Here is a bash script to reproduce the first issue using device-mapper.
The output files are:
|
The second issue (or something similar to the second issue) can be reproduced with this line: (A faulty sector is the last one.) |
Data becomes misaligned when a faulty sector is encountered on a source drive. NIST report, upstream patch.
An infinite loop when a faulty sector is encountered on a source drive (data is written to an output file until there is no space left). I observed this bug in dcfldd long ago (2014), I can't identify the buggy piece of code (it's hard to reproduce). Possibly related to the previous bug.
