I was able to resolve the issue caused by multiplexing where HEADER1+DATA1... was read as HEADER1+HEADER2+HEADER3...
So nbdcpy is functional! and copies completely. Though I have been trying to resolve another issue The command below works fine (16MB) nbdkit -v -o data ' ( 0x41 0x42 )*16777216 ' --run 'bin/nbdcpy $port $port' But when I use random `nbdkit -v -o random size=16M --run 'bin/nbdcpy $port $port'` I get error: data written does not match expected So, I assume my code is affected by data somehow which I am not able to find. As it's functional now I will update the documentation to make it more understandable and true to code and then ask for reviews from io_uring people. I will also resume work on documenting how libnbd works and on how to integrate io_uring with libnbd or nbdcopy.
