Monitor: handle optional '-' arg as a bool

Historically, user monitor arguments beginning with '-' (eg. '-f')
were passed as integers down to handlers.

I've maintained this behavior in the new monitor because we didn't
have a boolean type at the very beginning of QMP. Today we have it
and this behavior is causing trouble to QMP's argument checker.

This commit fixes the problem by doing the following changes:

1. User Monitor

   Before: the optional arg was represented as a QInt, we'd pass 1
           down to handlers if the user specified the argument or
           0 otherwise

   This commit: the optional arg is represented as a QBool, we pass
                true down to handlers if the user specified the
                argument, otherwise _nothing_ is passed

2. QMP

   Before: the client was required to pass the arg as QBool, but we'd
           convert it to QInt internally. If the argument wasn't passed,
           we'd pass 0 down

   This commit: still require a QBool, but doesn't do any conversion and
                doesn't pass any default value

3. Convert existing handlers (do_eject()/do_migrate()) to the new way

   Before: Both handlers would expect a QInt value, either 0 or 1

   This commit: Change the handlers to accept a QBool, they handle the
                following cases:

                   A) true is passed: the option is enabled
                   B) false is passed: the option is disabled
                   C) nothing is passed: option not specified, use
                                         default behavior

net: Fix VM start with '-net none'

Commit 50e32ea8f31035877decc10f1075aa0e619e09cb changed the behaviour
for the return type of net_client_init() when a nic type with no init
method was specified. 'none' is one such nic type. Instead of returning
0, which gets interpreted as an index into the nd_table[] array, we
switched to returning -1, which signifies an error as well.

That broke VM start with '-net none'. Testing was only done with the
monitor command 'pci_add', which doesn't fail.

The correct fix would still be to return 0+ values from
net_client_init() only when the return value can be used as an index to
refer to an entry in nd_table[]. With the current code, callers can
erroneously poke into nd_table[0] when -net nic is used, which can lead
to badness.

However, this commit just returns to the previous behaviour before the
offending commit.

14 years agomonitor: allow device to be ejected if no disk is inserted
Eduardo Habkost [Tue, 1 Jun 2010 22:12:19 +0000 (19:12 -0300)]
monitor: allow device to be ejected if no disk is inserted

This changes the monitor eject_device() function to not check for
bdrv_is_inserted().

Example run where the bug manifests itself:

(output of 'info block' is stripped to include only the CD-ROM device)

  (qemu) info block
  ide1-cd0: type=cdrom removable=1 locked=0 [not inserted]
  (qemu) change ide1-cd0 /dev/cdrom host_cdrom
  (qemu) info block
  ide1-cd0: type=cdrom removable=1 locked=0 file=/dev/cdrom ro=1 drv=host_cdrom encrypted=0
  (qemu) eject ide1-cd0
  (qemu) info block
  ide1-cd0: type=cdrom removable=1 locked=0 file=/dev/cdrom ro=1 drv=host_cdrom encrypted=0

  # at this point, a disk was inserted on the host CD-ROM drive

  (qemu) info block
  ide1-cd0: type=cdrom removable=1 locked=0 file=/dev/cdrom ro=1 drv=host_cdrom encrypted=0
  (qemu) eject ide1-cd0
  (qemu) info block
  ide1-cd0: type=cdrom removable=1 locked=0 [not inserted]
  (qemu)

The first eject command didn't work because the is_inserted() check
failed.

I have no clue why the code had the is_inserted() check, as it doesn't matter
if there is a disk present at the host drive, when the user wants the virtual
device to be disconnected from the host device.

The is_inserted() check has another side effect: a memory leak if the "change"
command is used multiple times, as do_change() calls eject_device() before
re-opening the block device, but bdrv_close() is never called.
