Subject: [PATCH v3 0/7] hw/scsi/spapr_vscsi: Fix time bomb buffer overflow
Date: Thu, 5 Mar 2020 13:12:46 +0100

This series fixes a possible buffer overflow.

Simples patches first (dissociate the buffer holding DMA
requests with pointer to SRP Information Unit packets) to
clean the issue in the penultimate patch.

- Fixed typo reported by Greg Kurz
- Addressed Paolo Bonzini review comments as an extra patch
- Added another patch converting a fprintf() call while here

- Addressed David Gibson review comments

Supersedes: <address@hidden>

Philippe Mathieu-Daudé (7):
  hw/scsi/viosrp: Add missing 'hw/scsi/srp.h' include
  hw/scsi/spapr_vscsi: Use SRP_MAX_IU_LEN instead of sizeof flexible
  hw/scsi/spapr_vscsi: Simplify a bit
  hw/scsi/spapr_vscsi: Introduce req_iu() helper
  hw/scsi/spapr_vscsi: Do not mix SRP IU size with DMA buffer size
  hw/scsi/spapr_vscsi: Prevent buffer overflow
  hw/scsi/spapr_vscsi: Convert debug fprintf() to trace event
