[Libguestfs] Re: [PATCH nbdkit v2 5/5] vddk: do_extents: Avoid reading partial chunk beyond the end of the disk

The QueryAllocatedBlocks API has (another) frustrating feature. It can only query whole "chunks" (128 sectors). If the disk size is not aligned to the chunk size (say the size was 129 sectors) then there's a bit at the end which cannot be queried. Furthermore, the API gives an error in this case instead of being helpful: VixDiskLib_QueryAllocatedBlocks: One of the parameters was invalid Fixes: https://issues.redhat.com/browse/RHEL-71694 --- tests/Makefile.am | 5 +- plugins/vddk/worker.c | 28 ++++++++- tests/test-vddk-real-unaligned-chunk.sh | 82 +++++++++++++++++++++++++ 3 files changed, 112 insertions(+), 3 deletions(-)
