[Qemu-devel] [PATCH for-2.4 0/3] scsi: fixes for failed requests


From: Stefan Hajnoczi
Subject: [Qemu-devel] [PATCH for-2.4 0/3] scsi: fixes for failed requests
Date: Thu, 30 Jul 2015 14:16:10 +0100

When requests fail the error policy (-drive rerror=,werror=) determines what
happens.  The 'stop' policy pauses the guest and waits for the administrator to
resolve the storage problem.  It is possible to live migrate during this time
and the failed requests can be restarted on the destination host.

Two bugs:
1. Segfault due to missing sgs mapping when loading migrated failed requests.
2. Incorrect error action due to broken is_read logic.

I also noticed that the unaligned WRITE SAME test case in
tests/virtio-scsi-test.c is broken.  I've included a fix for that too.

Stefan Hajnoczi (3):
  virtio-scsi: use virtqueue_map_sg() when loading requests
  scsi-disk: fix cmd.mode field typo
  tests: virtio-scsi: clear unit attention after reset
