Markus Armbruster c6bd8c706a qerror: Clean up QERR_ macros to expand into a single string
These macros expand into error class enumeration constant, comma,
string.  Unclean.  Has been that way since commit 13f59ae.

The error class is always ERROR_CLASS_GENERIC_ERROR since the previous
commit.

Clean up as follows:

* Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and
  delete it from the QERR_ macro.  No change after preprocessing.

* Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into
  error_setg(...).  Again, no change after preprocessing.

Markus Armbruster 70b9433109 QemuOpts: Wean off qerror_report_err()
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP.  It should not be used
elsewhere.

The only remaining user in qemu-option.c is qemu_opts_parse().  Is it
used in QMP context?  If not, we can simply replace
qerror_report_err() by error_report_err().

The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.

The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.

Remaining uses:

* drive_def(): Command line -drive and such, HMP drive_add and pci_add

* hmp_chardev_add(): HMP chardev-add

* monitor_parse_command(): HMP core

* tmp_config_parse(): Command line -tpmdev

* net_host_device_add(): HMP host_net_add

* net_client_parse(): Command line -net and -netdev

* qemu_global_option(): Command line -global

* vnc_parse_func(): Command line -display, -vnc, default display, HMP
  change, QMP change.  Bummer.

* qemu_pci_hot_add_nic(): HMP pci_add

* usb_net_init(): Command line -usbdevice, HMP usb_add

Propagate errors through qemu_opts_parse().  Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err().  Switch all non-QMP users outside tests to it.

That leaves vnc_parse_func().  Propagate errors through it.  Since I'm
touching it anyway, rename it to vnc_parse().

Greg Ungerer 8c52f0cbba m68k: implement more ColdFire 5208 interrupt controller functionality
Implement the SIMR and CIMR registers of the 5208 interrupt controller.
These are used by modern versions of Linux running on ColdFire (not sure
of the exact version they were introduced, but they have been in for quite
a while now).

Without this change when attempting to run a linux-3.5 kernel you will
see:

  qemu: hardware error: mcf_intc_write: Bad write offset 28

and execution will stop and dump out.

Paul Donohue ae46e23964 mc146818rtc: Reset the periodic timer on load
When loading a VM from a snapshot or migration, clock changes can cause
the periodic timer to stall or loop rapidly.

qemu-timer has a reset notifier mechanism that is used to avoid timer
stalls or loops if the host clock changes while the VM is running when
using QEMU_CLOCK_HOST.  However, when loading a snapshot or migration,
qemu-timer is initialized and fires the reset notifier before
mc146818rtc is initialized and has registered its reset handler.  In
addition, this mechanism isn't used when using QEMU_CLOCK_REALTIME,
which might also change when loading a snapshot or migration.

To correct that problem, this commit resets the periodic timer after
loading from a snapshot or migration if the clock has either jumped
backward or has jumped forward by more than the clock jump limit that
is used by the reset notifier code in qemu-timer.

Pankaj Gupta 1e7398a140 vhost: enable vhost without without MSI-X
We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.

This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.

This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

Shmulik Ladkani 74de5504fd pci: Don't register a specialized 'config_write' if default behavior is intended
Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.

This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.

Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

returned:

"No arbitrary length limit. Before the patch, it's 39 characters, and the

snprintf() is called with its first argument pointing beyond path[], and
its second argument underflowing to a huge size."

Greg Kurz 5be7d9f1b1 vhost-net: tell tap backend about the vnet endianness
The default behaviour for TAP/MACVTAP is to consider vnet as native endian.

This patch handles the cases when this is not true:
- virtio 1.0: always little-endian
- legacy cross-endian

Eduardo Habkost 473a49460d q35: Re-enable FDC on pc-q35-2.3 and older
commit ea96bc629c doesn't match the patch
submitted by Laszlo to qemu-devel. We reuse pc_q35_2_4_machine_options()
inside pc_q35_2_3_machine_options(), so we need to undo the no_floppy
change in pc_q35_2_3_machine_options().

(This discrepancy was due to a bad merge.)

This restores the previous behavior where all the 2.3 and older machines
had no_floppy=0.

Petr Matousek d4862a87e3 i8254: fix out-of-bounds memory access in pit_ioport_read()
Due converting PIO to the new memory read/write api we no longer provide
separate I/O region lenghts for read and write operations. As a result,
reading from PIT Mode/Command register will end with accessing
pit->channels with invalid index.

Fix this by ignoring read from the Mode/Command register.

This is CVE-2015-3214.

Scott Feldman 5ff1547b75 rocker: bring link up/down on PHY enable/disable
When the OS driver enables/disables the port, go ahead and set the port's
link status to up/down in response to the change.  This more closely
emulates real hardware when the PHY for the port is brought up/down
and the PHY negotiates carrier (link status) with link partner.  In
the case of qemu, the virtual rocker device can't really do link
negotiation with the link partner as that requires signally over a
physical medium (the wire), so just pretend the negotiation was
successful and bring the link up when the port is enabled.

Laszlo Ersek 4ebc736e99 i386/acpi-build: fix PXB workarounds for unsupported BIOSes
The patch

  apci: fix PXB behaviour if used with unsupported BIOS

uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:

  (!range_base || range_base > range_limit)

When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.

Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression

  (range_base || range_base > range_limit)

leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.

The correct negative of the condition seen at the top is

  (range_base && range_base <= range_limit)

Fix the expressions.

Laszlo Ersek c96d9286a6 i386/acpi-build: more traditional _UID and _HID for PXB root buses
The ACPI specification permits the _HID and _UID objects to evaluate to
strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in
the ACPI v6.0 spec.)

With regard to related standards, the UEFI specification can also express
a device address composed from string _HID and _UID identifiers, inside
the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table
49, in the UEFI v2.5 spec.)

However, numeric (integer) contents for both _HID and _UID are more
traditional. They are recommended by the UEFI spec for size reasons:

  [...] the ACPI Device Path node is smaller and should be used if
  possible to reduce the size of device paths that may potentially be
  stored in nonvolatile storage [...]

External tools support them better (for example the --acpi_hid and
--acpi_uid options of "efibootmgr" only take numeric identifiers).
Finally, numeric _HID and _UID contents are existing practice in the QEMU
source.

This patch was tested with a Fedora 20 LiveCD and a preexistent Windows
Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we
get, in the SSDT:

> Scope (\_SB)
> {
>   Device (PC04)
>   {
>     Name (_UID, 0x04)  // _UID: Unique ID
>     Name (_HID, EisaId ("PNP0A03") /* PCI Bus */)  // _HID: Hardware ID

Commit 94c2b6aff4 (mips_malta: support up to 2GiB RAM) provided
support for using over 256MB of RAM with the MIPS Malta board, including
capping the memsize variable that QEMUs pseudo-bootloader provides to
the kernel at 256MB in order to match YAMON. It didn't however provide
the ememsize variable which kernels supporting memory outside of the
unmapped address spaces (ie. EVA or highmem) may use to determine the
true size of the RAM present in the system.

Set ememsize to the size of RAM so that such kernels may use all
available memory without the user having to manually specifying its size
& location.

Jason Wang 975acc0ae6 virtio-pci: correctly set host notifiers for modern bar
Currently, during host notifier set. We only add eventfd for legacy
bar, this is not correct since:

- Non-transitional device does not have legacy bar, so qemu will crash
  since proxy->bar was not initialized.
- Modern device uses modern bar and notify cap to notify the device,
  we should add eventfd for proxy->notify.

So this patch fixes the above two issues by adding eventfd based on
whether legacy or modern device were supported.

Petr Matousek 9f7c594c00 pcnet: force the buffer access to be in bounds during tx
4096 is the maximum length per TMD and it is also currently the size of
the relay buffer pcnet driver uses for sending the packet data to QEMU
for further processing. With packet spanning multiple TMDs it can
happen that the overall packet size will be bigger than sizeof(buffer),
which results in memory corruption.

Fix this by only allowing to queue maximum sizeof(buffer) bytes.

This is CVE-2015-3209.

[Fixed 3-space indentation to QEMU's 4-space coding standard.

When the argument is zero, it doesn't stop, and returns the bit-wise

The callers that pass zero could just as well pass one, because their
callbacks can't return anything but zero:

* qemu_config_write()'s callback config_write_opts()

Gerd Hoffmann 11e66a15a0 ich9: implement SMI_LOCK
Add write mask for the smi enable register, so we can disable write
access to certain bits.  Open all bits on reset.  Disable write access
to GBL_SMI_EN when SMI_LOCK (in ich9 lpc pci config space) is set.
Write access to SMI_LOCK itself is disabled too.

Gerd Hoffmann bafc90bdc5 q35: implement TSEG
TSEG provides larger amounts of SMRAM than the 128 KB available with
legacy SMRAM and high SMRAM.

Route access to tseg into nowhere when enabled, for both cpus and
busmaster dma, and add tseg window to smram region, so cpus can access
it in smm mode.

Gerd Hoffmann 68c77acfb1 q35: implement SMRAM.D_LCK
Once the SMRAM.D_LCK bit has been set by the guest several bits in SMRAM
and ESMRAMC become readonly until the next machine reset.  Implement
this by updating the wmask accordingly when the guest sets the lock bit.
As the lock it itself is locked down too we don't need to worry about
the guest clearing the lock bit.

Gerd Hoffmann b66a67d751 q35: add config space wmask for SMRAM and ESMRAMC
Not all bits in SMRAM and ESMRAMC can be changed by the guest.
Add wmask defines accordingly and set them in mch_reset().

Gerd Hoffmann 7744752402 q35: fix ESMRAMC default
The cache bits in ESMRAMC are hardcoded to 1 (=disabled) according to
the q35 mch specs.  Add and use a define with this default.

While being at it also update the SMRAM default to use the name (no code
change, just makes things a bit more readable).

Paolo Bonzini 64130fa4a1 q35: implement high SMRAM
When H_SMRAME is 1, low memory at 0xa0000 is left alone by
SMM, and instead the chipset maps the 0xa0000-0xbffff window at
0xfeda0000-0xfedbffff.  This affects both the "non-SMM" view controlled
by D_OPEN and the SMM view controlled by G_SMRAME, so add two new
MemoryRegions and toggle the enabled/disabled state of all four
in mch_update_smram.

Paolo Bonzini 3de70c0899 hw/i386: remove smram_update
It's easier to inline it now that most of its work is done by the CPU
(rather than the chipset) through /machine/smram and the memory API.

Paolo Bonzini f809c60512 target-i386: use memory API to implement SMRAM
Remove cpu_smm_register and cpu_smm_update.  Instead, each CPU
address space gets an extra region which is an alias of
/machine/smram.  This extra region is enabled or disabled
as the CPU enters/exits SMM.
