2014-07-01virtio-scsi: scsi events must be converted to target endiannessCédric Le Goater1-2/+2
Virtio SCSI Events need to be byteswapped before being pushed when host and guest have a different endianness. Not doing so breaks hotplug of virtio scsi disks, with the following error message being printed in the guest console: virtio_scsi: Unsupport virtio scsi event 1000000 This issue got uncovered while testing disk hotplug with a PowerKVM ppc64le guest. I have checked that this issue also affects a x86_64 guest run on a ppc64 host.

2014-07-01virtio-scsi: virtio_scsi_push_event() lacks VirtIOSCSIReq parsingGreg Kurz1-7/+1
Hotplug of a virtio scsi disk is currently broken: no disk appears in the guest (verified with a fedora 20 host running a fedora 20 guest with KVM). Bisect leeds to Paolo's patches to support any_layout, especially this commit: commit 36b15c79aa1bef5fe7543f9f2629b6413720bbfb Author: Paolo Bonzini <pbonzini@redhat.com> Date: Tue Jun 10 16:21:18 2014 +0200 virtio-scsi: start preparing for any_layout It modifies virtio_scsi_pop_req() so that it is up to the callers to parse the virtio scsi request. It seems that virtio_scsi_push_event() was not modified accordingly... This patch adds a call to virtio_scsi_parse_req().

2014-05-05virtio-scsi: fix buffer overrun on invalid state loadMichael S. Tsirkin1-0/+9
CVE-2013-4542 hw/scsi/scsi-bus.c invokes load_request. virtio_scsi_load_request does: qemu_get_buffer(f, (unsigned char *)&req->elem, sizeof(req->elem)); this probably can make elem invalid, for example, make in_num or out_num huge, then: virtio_scsi_parse_req(s, vs->cmd_vqs[n], req); will do: if (req->elem.out_num > 1) { qemu_sgl_init_external(req, &req->elem.out_sg[1], &req->elem.out_addr[1], req->elem.out_num - 1); } else { qemu_sgl_init_external(req, &req->elem.in_sg[1], &req->elem.in_addr[1], req->elem.in_num - 1); } and this will access out of array bounds. Note: this adds security checks within assert calls since SCSIBusInfo's load_request cannot fail. For now simply disable builds with NDEBUG - there seems to be little value in supporting these.

2014-03-05spapr_vscsi: Fix REPORT_LUNS handlingNathan Whitehorn1-0/+60
Intercept REPORT_LUNS commands addressed either to SRP LUN 0 or the well-known LUN for REPORT_LUNS commands. This is required to implement the SAM and SPC specifications. Since SRP implements only a single SCSI target port per connection, the SRP target is required to report all available LUNs in response to a REPORT_LUNS command addressed either to LUN 0 or the well-known LUN. Instead, QEMU was forwarding such requests to the first QEMU SCSI target, with the result that initiators that relied on this feature would only see LUNs on the first QEMU SCSI target. Behavior for REPORT_LUNS commands addressed to any other LUN is not specified by the standard and so is left unchanged. This preserves behavior under Linux and SLOF, which enumerate possible LUNs by hand and so address no commands either to LUN 0 or the well-known REPORT_LUNS LUN.
