      block: move has_variable_length to BlockLimits · 160a29e2
      Paolo Bonzini authored 
      
At the protocol level, has_variable_length only needs to be true in the
very special case of host CD-ROM drives, so that they do not need an
explicit monitor command to read the new size when a disc is loaded
in the tray.

However, at the format level has_variable_length has to be true for all
raw blockdevs and for all filters, even though in practice the length
depends on the underlying file and thus will not change except in the
case of host CD-ROM drives.

As a first step towards computing an accurate value of has_variable_length,
add the value into the BlockLimits structure and initialize the field
from the BlockDriver.

      block/vhdx: fix dynamic VHDX BAT corruption · 8af037fe
      Lukas Tschoke authored 
      The corruption occurs when a BAT entry aligned to 4096 bytes is changed.

Specifically, the corruption occurs during the creation of the LOG Data
Descriptor. The incorrect behavior involves copying 4088 bytes from the
original 4096 bytes aligned offset to `tmp[8..4096]` and then copying
the new value for the first BAT entry to the beginning `tmp[0..8]`.
This results in all existing BAT entries inside the 4K region being
incorrectly moved by 8 bytes and the last entry being lost.

This bug did not cause noticeable corruption when only sequentially
writing once to an empty dynamic VHDX (e.g.
using `qemu-img convert -O vhdx -o subformat=dynamic ...`), but it
still resulted in invalid values for the (unused) Sector Bitmap BAT
entries.

Importantly, this corruption would only become noticeable after the
corrupted BAT is re-read from the file.

      We can arrive here on _WIN64 because Int128 is passed by reference.
Change the assert to check that the immediate is in range,
instead of attempting to check the host ABI.
