scsi: Error locations for -drive if=scsi device initialization
Signed-off-by: Markus Armbruster <armbru@redhat.com>Signed-off-by: Kevin Wolf <kwolf@redhat.com>
qdev: Decouple qdev_prop_drive from DriveInfo
Make the property point to BlockDriverState, cutting out the DriveInfomiddleman. This prepares the ground for block devices that don't havea DriveInfo.
Currently all user-defined ones have a DriveInfo, because the only way...
block: Catch attempt to attach multiple devices to a blockdev
For instance, -device scsi-disk,drive=foo -device scsi-disk,drive=foohappily creates two SCSI disks connected to the same block device.It's all downhill from there.
Device usb-storage deliberately attaches twice to the same blockdev,...
scsi: scsi_bus_legacy_handle_cmdline() can fail, fix callers
None of its callers checks for failure. scsi_hot_add() can crashbecause of that:
(qemu) drive_add 4 if=scsi,format=host_device,file=/dev/sg1scsi-generic: scsi generic interface too oldSegmentation fault (core dumped)...
scsi-bus: Add PERSISTENT_RESERVE_OUT SCSIRequest->cmd.mode setup
This patch updates hw/scsi-bus.c to add the PERSISTENT_RESERVE_OUT cdbcase in scsi_req_xfer_mode() to set SCSI_XFER_TO_DEV for outgoing WRITE data.

scsi-bus: Add MAINTENANCE_IN and MAINTENANCE_OUT SCSIRequest xfer and mode assignments
This patch updates hw/scsi-bus.c to add MAINTENANCE_IN and MAINTENANCE_OUT case inscsi_req_length() for TYPE_ROM with MMC commands. It also adds the MAINTENANCE_OUTcase in scsi_req_xfer_mode() to set SCSI_XFER_TO_DEV for outgoing write data....
blockdev: Collect block device code in new blockdev.c
Anything that moves hundreds of lines out of vl.c can't be all bad.
error: Replace qemu_error() by error_report()
error_report() terminates the message with a newline. Strip it itfrom its arguments.
This fixes a few error messages lacking a newline:net_handle_fd_param()'s "No file descriptor named %s found", andtap_open()'s "vnet_hdr=1 requested, but no kernel support for...
error: Move qemu_error & friends into their own header
scsi: fix Sparse warning: Initializer entry defined twice
Both REWIND and REZERO_UNIT use 0x01, READ_POSITION and PRE_FETCHshare 0x34.

scsi-disk: restruct emulation: GET_CONFIGURATION
Move GET_CONFIGURATION emulation from scsi_send_command() toscsi_disk_emulate_command().
Also add GET_CONFIGURATION to scsi-defs.h and scsi_command_name().

scsi-disk: restruct emulation: SERVICE_ACTION_IN
Move SERVICE_ACTION_IN emulation from scsi_send_command() toscsi_disk_emulate_command().
Also add SERVICE_ACTION_IN to scsi-defs.h and scsi_command_name().
scsi-disk: restruct emulation: REPORT_LUNS
Move REPORT_LUNS emulation from scsi_send_command() toscsi_disk_emulate_command().
Also add REPORT_LUNS to scsi-defs.h and scsi_command_name().

scsi: add read/write 16 commands.
Add READ_16 + friends to scsi-defs.h, scsi_command_name() and therequest parsing helper functions.
Use them in scsi-disk.c too.
scsi: add scsi_req_print()
Handy for debugging.
scsi: add xfer mode
scsi: move sense to SCSIDevice, create SCSISense struct.
scsi: move status to SCSIRequest.
Also add and use the scsi_req_complete() helper function for calling thecompletion callback.
scsi: move request lists to QTAILQ.
Changes: * Move from open-coded lists to QTAILQ macros. * Move the struct elements to the common data structures (SCSIDevice + SCSIRequest). * Drop free request pools. * Fix request cleanup in the destroy callback....
scsi: move SCSIRequest management to common code.
Create generic functions to allocate, find and release SCSIRequeststructs. Make scsi-disk and scsi-generic use them.
scsi: add request parsing helpers to common code.
Add helper functions for scsi request parsing to common code. Gettingcommand length, transfer size, and linear block address is handled.
scsi: move scsi-disk.h -> scsi.h
Check return value of qdev_init()
But do so only where it may actually fail. Leave the rest for thenext commit.

scsi: hotplug windup
Implement scsi device destruction
switch scsi bus to inplace allocation.
qdev/scsi: add scsi bus support to qdev, convert drivers.
Adding scsi disks via -device works now, i.e. you can do:
-drive id=sda,if=none,......
