f524bc3b3d Xen: use qemu_strtoul instead of strtol
No need to roll our own (with slightly incorrect handling of errno),
when we can use the common version.

Change signed parsing to unsigned, because what it read are values in
PCI config space, which are non-negative.

dced4d2fcb xen-hvm: Clean up xen_hvm_init() error handling
xen_hvm_init() returns -1 without cleaning up on some errors (harmless
long as the caller exit()s on error), dies with hw_error() on others.
hw_error() isn't approprate here.  Clean up to exit() on all errors.

ac0487e1d2 xenfb.c: avoid expensive loops when prod <= out_cons
If the frontend sets out_cons to a value higher than out_prod, it will
cause xenfb_handle_events to loop about 2^32 times. Avoid that by using
better checks at the beginning of the function.

193227f9e5 error: Use error_report_err() instead of monitor_printf()
Both error_report_err() and monitor_printf() print to the same
destination when monitor_printf() is used correctly, i.e. within an
HMP monitor.  Elsewhere, monitor_printf() does nothing, while
error_report_err() reports to stderr.

Most changed functions are HMP command handlers.  These should only
run within an HMP monitor.  The one exception is bdrv_password_cb(),
which should also only run within an HMP monitor.

Four command handlers prefix the error message with the command name:
balloon, migrate_set_capability, migrate_set_parameter, migrate.
Pointless, drop.

Unlike monitor_printf(), error_report_err() uses the error whole
instead of just its message obtained with error_get_pretty().  This
avoids suppressing its hint (see commit 50b7b00).  Example:

    (qemu) device_add ivshmem,id=666
    Parameter 'id' expects an identifier
    Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.
    Try "help device_add" for more information

The "Identifiers consist of..." line is new with this patch.

675463d9b6 isa: Clean up inappropriate hw_error()
isa_bus_irqs(), isa_create() and isa_try_create() call hw_error() when
passed a null bus.  Use of hw_error() has always been questionable,
because these are used only during machine initialization, and
printing CPU registers isn't useful there.

Since the previous commit, passing a null bus is a programming error.
Drop the hw_error() and simply let it crash.

d10e54329b isa: Clean up error handling around isa_bus_new()
We can have at most one ISA bus.  If you try to create another one,
isa_bus_new() complains to stderr and returns null.

isa_bus_new() is called in two contexts, machine's init() and device's
realize() methods.  Since complaining to stderr is not proper in the
latter context, convert isa_bus_new() to Error.

Machine's init():

* mips_jazz_init(), called from the init() methods of machines
  "magnum" and "pica"

* mips_r4k_init(), the init() method of machine "mips"

* pc_init1() called from the init() methods of non-q35 PC machines

* typhoon_init(), called from clipper_init(), the init() method of
  machine "clipper"

These callers always create the first ISA bus, hence isa_bus_new()
can't fail.  Simply pass &error_abort.

Device's realize():

* i82378_realize(), of PCI device "i82378"

* ich9_lpc_realize(), of PCI device "ICH9-LPC"

* pci_ebus_realize(), of PCI device "ebus"

* piix3_realize(), of PCI device "pci-piix3", abstract parent of
  "PIIX3" and "PIIX3-xen"

* piix4_realize(), of PCI device "PIIX4"

* vt82c686b_realize(), of PCI device "VT82C686B"

Propagate the error.  Note that these devices are typically created
only by machine init() methods with qdev_init_nofail() or similar.  If
we screwed up and created an ISA bus before that call, we now give up
right away.  Before, we'd hobble on, and typically die in
isa_bus_irqs().  Similar if someone finds a way to hot-plug one of
these critters.

c72fbf98cb sysbus: Don't use hw_error() in machine_init_done_notifiers
platform_bus_map_irq() and platform_bus_map_mmio() use hw_error() to
fail.  They run in machine_init_done_notifiers, via
platform_bus_init_notify() and link_sysbus_device().  Printing CPU
registers is not helpful there.

Replace hw_error() by error_report(); exit(1).  If these are
programming errors, it should be replaced by an assertion instead.

While there, observe that both functions always return 0, and
link_sysbus_device() ignores the return value.  Change them to void.

7b55044f9d hw/arm/virt: Fix property "gic-version" error handling
virt_set_gic_version() calls exit(1) when passed an invalid property
value.  Property setters are not supposed to do that.  Screwed up in
commit b92ad39.  Harmless, because the property belongs to a machine.
Set an error object instead.

9280eb34de raven: Mark use of hw_error() in realize() FIXME
Device realize() methods aren't supposed to call hw_error(), they
should set an error and fail cleanly.  Blindly doing that would be
easy enough, but then realize() would fail without undoing its side
effects.  Just mark it FIXME for now.

84a3a53cf6 omap: Don't use hw_error() in device init() methods
Device init() methods aren't supposed to call hw_error(), they should
report the error and fail cleanly.  Do that.

The errors are all device misconfiguration.  All callers use
qdev_init_nofail(), so this patch merely converts hw_error() crashes
into &error_abort crashes.  Improvement, because now it crashes closer
to where the misconfiguration bug would be, and a few more bad
examples of hw_error() use are gone.

Printing CPU registers is not helpful during machine initialization.
Moreover, these are straightforward configuration or "can get

hw_error() by error_report(); exit(1).  Matches how we report these
errors in other machine initializations.

4ab0359a8a ide: ahci: reset ncq object to unused on error
When processing NCQ commands, AHCI device emulation prepares a
NCQ transfer object; To which an aio control block(aiocb) object
is assigned in 'execute_ncq_command'. In case, when the NCQ
command is invalid, the 'aiocb' object is not assigned, and NCQ
transfer object is left as 'used'. This leads to a use after
free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
Reset NCQ transfer object to 'unused' to avoid it.
