The additional output demonstrates we screw up when -global isa-fdc
clashes with -drive if=floppy or its sugared forms: according to "info
qtree", only the latter backend is attached, but according to "info
block", both are.  For instance:

    Testing: -fda TEST_DIR/t.qcow2 -drive if=none,file=TEST_DIR/t.qcow2.2 -global isa-fdc.driveA=none0

	      dev: isa-fdc, id ""
	        [...]
		driveA = ""
		driveB = ""
                [...]
                bus: floppy-bus.0
                  type floppy-bus
                  dev: floppy, id ""
                    unit = 0 (0x0)
--->                drive = "floppy0"
    [...]
    floppy0 (NODE_NAME): TEST_DIR/t.qcow2 (qcow2)
--->    Attached to:      /machine/unattached/device[15]
        Removable device: not locked, tray closed
        Cache mode:       writeback

    none0 (NODE_NAME): TEST_DIR/t.qcow2.2 (qcow2)
--->    Attached to:      /machine/unattached/device[14]
        Cache mode:       writeback

/machine/unattached/device[15] is floppy, and
/machine/unattached/device[14] is isa-fdc.

  To: qemu-devel

Use of -global to set a default backend for non-singleton devices is a
bad idea.  But as long as we permit it, we better test it.

Test output demonstrates we screw up when -global floppy clashes with
-fda or with -device floppy: according to "info qtree", only the
latter backend is attached, but according to "info block", both are.
Here's the clash with -device:

    Testing: -drive if=none,file=TEST_DIR/t.qcow2 -drive if=none,file=TEST_DIR/t.qcow2.2 -global floppy.drive=none0 -device floppy,drive=none1,unit=0

              dev: isa-fdc, id ""
                [...]
                driveA = ""
                driveB = ""
                [...]
                bus: floppy-bus.0
                  type floppy-bus
                  dev: floppy, id ""
                    unit = 0 (0x0)
--->                drive = "none1"
    [...]
    none0 (NODE_NAME): TEST_DIR/t.qcow2 (qcow2)
--->    Attached to:      /machine/peripheral-anon/device[0]
        Cache mode:       writeback

    none1 (NODE_NAME): TEST_DIR/t.qcow2.2 (qcow2)
--->    Attached to:      /machine/peripheral-anon/device[0]
        Removable device: not locked, tray closed
        Cache mode:       writeback

/machine/peripheral-anon/device[0] is the floppy created with -device.

Test output further demonstrates the "Drive 'FOO' is already in use
because it has been automatically connected to another device" error
message can be misleading.  With '-fda "" -global
floppy.drive=floppy0', it's in use because -global reuses -fda's
backend.  There is no other device involved.

From: Markus Armbruster @ 2020-06-23 14:23 UTC (permalink / raw)
  To: qemu-devel

The floppy controller devices desugar their drive properties into
floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to
FloppyDrive", v2.8.0).  This involves some bad magic in
fdctrl_connect_drives(), and exists for backward compatibility.

The functions for boards to create floppy controller devices
fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init()
desugar -drive if=floppy to these floppy controller drive properties.

If you use both -drive if=floppy (or its -fda / -fdb sugar) and
-global isa-fdc for the same floppy device, -global silently loses the
conflict, and both backends involved end up with the floppy device
frontend attached, as demonstrated by iotest 172 (see commit before
previous).  This is wrong.

Desugar -drive if=floppy straight to floppy devices instead, with
helper fdctrl_init_drives().  The conflict now gets rejected cleanly:
first, fdctrl_connect_drives() creates the floppy for the controller's
property, then fdctrl_init_drives() attempts to create the floppy for
-drive if=floppy, but fails because the unit is already in use.

Output of iotest 172 changes in three ways:

1. The clash gets rejected.

2. In one test case, "info qtree" has the floppy devices swapped, and
   "info block" has their QOM paths swapped.  This is because the
   floppy device for -fda now gets created after the one for -global
   isa-fdc.driveB.

3. The error message for -global floppy.drive=floppy0 changes.  Before
   the patch, we set isa-fdc.driveA to -fda's block backend, then
   create the floppy device for it, then move the backend from
   isa-fdc.driveA to floppy.drive.  Floppy creation fails when
   applying -global floppy.drive=floppy0, because floppy0 is still
   attached to isa-fdc.  After the patch, we create the floppy for
   -fda, then set its drive property to floppy0.  Now floppy creation
   succeeds, but setting the drive property fails, because -global
   already set it.  Yes, this is exasperatingly complicated.

Helper function fdctrl_init_isa() is less than helpful: one of three
places creating "isa-fdc" devices use it.  Open-code it there, and
drop the function.

Deprecate

    -global isa-fdc.driveA=...
    -global isa-fdc.driveB=...

in favour of

    -device floppy,unit=0,drive=...
    -device floppy,unit=1,drive=...

Same for the other floppy controller devices.

Drives with interface types other than if=none are for onboard
devices.  Unfortunately, any such drives the board doesn't pick up can
still be used with -device, like this:

    $ qemu-system-x86_64 -nodefaults -display none -S -drive if=floppy,id=bogus,unit=7 -device ide-cd,drive=bogus -monitor stdio
    QEMU 5.0.50 monitor - type 'help' for more information
    (qemu) info block
    bogus: [not inserted]
	Attached to:      /machine/peripheral-anon/device[0]
	Removable device: not locked, tray closed
    (qemu) info qtree
    bus: main-system-bus
      type System
      [...]
	    bus: ide.1
	      type IDE
	      dev: ide-cd, id ""
--->		drive = "bogus"
		[...]
		unit = 0 (0x0)
      [...]

This kind of abuse has always worked.  Deprecate it:

We stopped using get_pointer() and set_pointer() for netdev in commit
23120b13c6 "net: don't use set/get_pointer() in set/get_netdev()"
(v2.3.0), and for chardev in commit becdfa00cf "char: replace PROP_CHR
with CharBackend" (v2.8.0).  With only the drive user left, they're
not helpful anymore.  Eliminate.

  To: qemu-devel; +Cc: Jason Wang

qdev_prop_set_netdev() fails when the property already has a non-null
value.  Seems to go back to commit 30c367ed44
"qdev-properties-system.c: Allow vlan or netdev for -device, not
both", v1.7.0.  Board code doesn't expect failure, and crashes:

    $ qemu-system-x86_64 --nodefaults -nic user -netdev user,id=nic0 -global e1000.netdev=nic0
    Unexpected error in error_set_from_qdev_prop_error() at /work/armbru/qemu/hw/core/qdev-properties.c:1101:
    qemu-system-x86_64: Property 'e1000.netdev' doesn't take value '__org.qemu.nic0
    '
    Aborted (core dumped)

-device and device_add handle the failure:

    $ qemu-system-x86_64 -nodefaults -netdev user,id=net0 -netdev user,id=net1 -device e1000,netdev=net0,netdev=net1
    qemu-system-x86_64: -device e1000,netdev=net0,netdev=net1: Property 'e1000.netdev' doesn't take value 'net1'
    $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -netdev user,id=net0 -netdev user,id=net1 -global e1000.netdev=net0
    QEMU 5.0.50 monitor - type 'help' for more information
    (qemu) qemu-system-x86_64: warning: netdev net0 has no peer

    device_add e1000,netdev=net1
    Error: Property 'e1000.netdev' doesn't take value 'net1'

Perhaps netdev property override could be made to work.  Perhaps it
should.  I'm not the right guy to figure this out.  What I can do is
improve the error message a bit:

    (qemu) device_add e1000,netdev=net1
    Error: -global e1000.netdev=... conflicts with netdev=net1

  To: qemu-devel

qdev_prop_set_drive() screws up when the property already has a
non-null value: it neglects to release the old value.  Both the old
and the new backend become attached to the same device.

Example (taken from iotest 172): -fda ... -drive if=none,... -global
floppy.drive=none0.

Special case: attempting to use the same backend both times fails.
Example (also from iotest 172): -fda ... -global floppy.drive=floppy0.

Yet another example: -device with multiple drive=... (but not
device_add, which silently drops all but the last duplicate property).

Perhaps drive property override could be made to work.  Perhaps it
should.  I can't afford the time to figure this out now.  What I can
do is reject usage that leaves backends in unhealthy states.  For what
it's worth, we've long done the same for netdev properties.

qdev_prop_set_chr() screws up when the property already has a non-null
value: it neglects to release the old value.  Both the old and the new
backend become attached to the same device.  Unlike for block devices
(see previous commit), this can't be observed from the monitor (I
think).

Example: -serial null -chardev null,id=chr0 -global isa-serial.chardev=chr0

Special case: attempting to use the same backend both times crashes:

    $ qemu-system-x86_64 --nodefaults -serial null -global isa-serial.chardev=serial0
    Unexpected error in qemu_chr_fe_init() at /work/armbru/qemu/chardev/char-fe.c:220:
    qemu-system-x86_64: Device 'serial0' is in use
    Aborted (core dumped)

Yet another example: -device with multiple chardev=... (but not
device_add, which silently drops all but the last duplicate property).

Perhaps chardev property override could be made to work.  Perhaps it
should.  I can't afford the time to figure this out now.  What I can
do reject usage that leaves backends in unhealthy states.  For what
it's worth, we've long done the same for netdev properties.

qdev_prop_set_drive() can fail.  None of the other qdev_prop_set_FOO()
can; they abort on error.

To clean up this inconsistency, rename qdev_prop_set_drive() to
qdev_prop_set_drive_err(), and create a qdev_prop_set_drive() that
aborts on error.

We always pass &error_abort.  Drop the parameter, use &error_abort
directly.

On error, pxa2xx_mmci_init() reports to stderr and returns NULL.
Callers don't check for errors.  Machines akita, borzoi, mainstone,
spitz, terrier, tosa, and z2 crash shortly after, like this:

    $ qemu-system-aarch64 -M akita -drive if=sd,readonly=on
    qemu-system-aarch64: failed to init SD card: Cannot use read-only drive as SD card
    Segmentation fault (core dumped)

Machines connex and verdex reach the check for orphaned drives first:

    $ aarch64-softmmu/qemu-system-aarch64 -M connex -drive if=sd,readonly=on -accel qtest
    qemu-system-aarch64: failed to init SD card: Cannot use read-only drive as SD card
    qemu-system-aarch64: -drive if=sd,readonly=on: machine type does not support if=sd,bus=0,unit=0

Make pxa2xx_mmci_init() fail cleanly right away.

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

milkymist_memcard_realize() is wrong that way: it passes &err to
qdev_prop_set_drive_err() and qdev_realize_and_unref().  Currently
harmless, because the latter uses it only as first argument of
error_propagate().

Making qdev_prop_set_drive_err() fail involves abuse of -global.
Leave handling that to qdev_prop_set_drive(), like we do elsewhere.
