5b7236f725 cadence_uart: bounds check write offset
cadence_uart_init() initializes an I/O memory region of size 0x1000
bytes.  However in uart_write(), the 'offset' parameter (offset within
region) is divided by 4 and then used to index the array 'r' of size
CADENCE_UART_R_MAX which is much smaller: (0x48/4).  If 'offset>>=2'
exceeds CADENCE_UART_R_MAX, this will cause an out-of-bounds memory
write where the offset and the value are controlled by guest.

This will corrupt QEMU memory, in most situations this causes the vm to
crash.

Fix by checking the offset against the array size.

706bab670b ehci: apply limit to iTD/sidt descriptors
Commit "156a2e4 ehci: make idt processing more robust" tries to avoid a
DoS by the guest (create a circular iTD queue and let qemu ehci
emulation run in circles forever).  Unfortunately this has two problems:
First it misses the case of siTDs, and second it reportedly breaks
FreeBSD.

So lets go for a different approach: just count the number of iTDs and
siTDs we have seen per frame and apply a limit.  That should really
catch all cases now.

44b86aa32e vga: make sure vga register setup for vbe stays intact (CVE-2016-3712).
Call vbe_update_vgaregs() when the guest touches GFX, SEQ or CRT
registers, to make sure the vga registers will always have the
values needed by vbe mode.  This makes sure the sanity checks
applied by vbe_fixup_regs() are effective.

Without this guests can muck with shift_control, can turn on planar
vga modes or text mode emulation while VBE is active, making qemu
take code paths meant for CGA compatibility, but with the very
large display widths and heigts settable using VBE registers.

Which is good for one or another buffer overflow.  Not that
critical as they typically read overflows happening somewhere
in the display code.  So guests can DoS by crashing qemu with a
segfault, but it is probably not possible to break out of the VM.

4f0323d26c vga: fix banked access bounds checking (CVE-2016-3710)
vga allows banked access to video memory using the window at 0xa00000
and it supports a different access modes with different address
calculations.

The VBE bochs extentions support banked access too, using the
VBE_DISPI_INDEX_BANK register.  The code tries to take the different
address calculations into account and applies different limits to
VBE_DISPI_INDEX_BANK depending on the current access mode.

Which is probably effective in stopping misprogramming by accident.
But from a security point of view completely useless as an attacker
can easily change access modes after setting the bank register.

Drop the bogus check, add range checks to vga_mem_{readb,writeb}
instead.

5f409b108f hyperv: cpu hotplug fix with HyperV enabled
With Hyper-V enabled CPU hotplug stops working. The CPU appears
in device manager on Windows but does not appear in peformance
monitor and control panel.

The root of the problem is the following. Windows checks
HV_X64_CPU_DYNAMIC_PARTITIONING_AVAILABLE bit in CPUID. The
presence of this bit is enough to cure the situation.

The bit should be set when CPU hotplug is allowed for HyperV VM.
The check that hot_add_cpu callback is defined is enough from the
protocol point of view. Though this callback is defined almost
always thus there is no need to export that knowledge in the
other way.

A null pointer dereference issue was reported by Mr Ling Liu, CC'd here. It
occurs while doing I/O port write operations via hmp interface. In that,
'current_cpu' remains null as it is not called from cpu_exec loop, which
results in the said issue.

Below is a proposed (tested)patch to fix this issue; Does it look okay?

a2ae168821 migration: allow machine to enforce configuration section migration
Migration of pseries-2.3 doesn't have configuration section. Unfortunately,
QEMU 2.4/2.4.1/2.5 are buggy and always stream and expect the configuration
section, and break migration both ways.

This patch introduces a property which allows to enforce a configuration
section for machines who don't have one.

It can be set at startup:

-machine enforce-config-section=on

or later from the QEMU monitor:

qom-set /machine enforce-config-section on

It is up to the tooling to set or unset this property according to the
version of the QEMU at the other end of the pipe.

cab1cc7245 target-arm: Make reserved ranges in ID_AA64* spaces RAZ, not UNDEF
The v8 ARM ARM defines that unused spaces in the ID_AA64* system
register ranges are Reserved and must RAZ, rather than being UNDEF.
Implement this.

In particular, ARM v8.2 adds a new feature register ID_AA64MMFR2,
and newer versions of the Linux kernel will attempt to read this,
which causes them not to boot up on versions of QEMU missing this fix.

Since the encoding .opc0 = 3, .opc1 = 0, .crn = 0, .crm = 2, .opc2 = 6
is actually defined in ARMv8 (as ID_MMFR4), we give it an entry in
the ARMCPU struct so CPUs can override it, though since none do
this too will just RAZ.

30929793b0 fw_cfg: unbreak migration compatibility for 2.4 and earlier machines
When I reviewed Marc's fw_cfg DMA patches, I completely missed that the
way we set dma_enabled would break migration.

Gerd explained the right way (see reference below): dma_enabled should be
set to true by default, and only true->false transitions should be
possible:

- when the user requests that with

    -global fw_cfg_mem.dma_enabled=off

  or

   -global fw_cfg_io.dma_enabled=off

  as appropriate for the platform,

- when HW_COMPAT_2_4 dictates it,

- when board code initializes fw_cfg without requesting DMA support.

c06f342009 spapr: skip configuration section during migration of older machines
Since QEMU 2.4, we have a configuration section in the migration stream.
This must be skipped for older machines, like it is already done for x86.

This patch fixes the migration of pseries-2.3 from/to QEMU 2.3, but it
breaks migration of the same machine from/to QEMU 2.4/2.4.1/2.5. We do
that anyway because QEMU 2.3 is likely to be more widely deployed than
newer QEMU versions.

cb873eaa6d e1000: eliminate infinite loops on out-of-bounds transfer start
The start_xmit() and e1000_receive_iov() functions implement DMA transfers
iterating over a set of descriptors that the guest's e1000 driver
prepares:

- the TDLEN and RDLEN registers store the total size of the descriptor
  area,

- while the TDH and RDH registers store the offset (in whole tx / rx
  descriptors) into the area where the transfer is supposed to start.

Each time a descriptor is processed, the TDH and RDH register is bumped
(as appropriate for the transfer direction).

QEMU already contains logic to deal with bogus transfers submitted by the
guest:

- Normally, the transmit case wants to increase TDH from its initial value
  to TDT. (TDT is allowed to be numerically smaller than the initial TDH
  value; wrapping at or above TDLEN bytes to zero is normal.) The failsafe
  that QEMU currently has here is a check against reaching the original
  TDH value again -- a complete wraparound, which should never happen.

- In the receive case RDH is increased from its initial value until
  "total_size" bytes have been received; preferably in a single step, or
  in "s->rxbuf_size" byte steps, if the latter is smaller. However, null
  RX descriptors are skipped without receiving data, while RDH is
  incremented just the same. QEMU tries to prevent an infinite loop
  (processing only null RX descriptors) by detecting whether RDH assumes
  its original value during the loop. (Again, wrapping from RDLEN to 0 is
  normal.)

What both directions miss is that the guest could program TDLEN and RDLEN
so low, and the initial TDH and RDH so high, that these registers will
immediately be truncated to zero, and then never reassume their initial
values in the loop -- a full wraparound will never occur.

The condition that expresses this is:

  xdh_start >= s->mac_reg[XDLEN] / sizeof(desc)

i.e., TDH or RDH start out after the last whole rx or tx descriptor that
fits into the TDLEN or RDLEN sized area.

This condition could be checked before we enter the loops, but
pci_dma_read() / pci_dma_write() knows how to fill in buffers safely for
bogus DMA addresses, so we just extend the existing failsafes with the
above condition.

This is CVE-2016-1981.

a375e0b03e block: set device_list.tqe_prev to NULL on BDS removal
This fixes a regression introduced with commit 3f09bfbc7.  Multiple
bugs arise in conjunction with live snapshots and mirroring operations
(which include active layer commit).

After a live snapshot occurs, the active layer and the base layer both
have a non-NULL tqe_prev field in the device_list, although the base
node's tqe_prev field points to a NULL entry.  This non-NULL tqe_prev
field occurs after the bdrv_append() in the external snapshot calls
change_parent_backing_link().

In change_parent_backing_link(), when the previous active layer is
removed from device_list, the device_list.tqe_prev pointer is not
set to NULL.

The operating scheme in the block layer is to indicate that a BDS belongs
in the bdrv_states device_list iff the device_list.tqe_prev pointer
is non-NULL.

This patch does two things:

1.) Introduces a new block layer helper bdrv_device_remove() to remove a
    BDS from the device_list, and
2.) uses that new API, which also fixes the regression once used in
    change_parent_backing_link().

a38a283fc7 qmp: Fix reference-counting of qnull on empty output visit
Commit 6c2f9a15 ensured that we would not return NULL when the
caller used an output visitor but had nothing to visit. But
in doing so, it added a FIXME about a reference count leak
that could abort qemu in the (unlikely) case of SIZE_MAX such
visits (more plausible on 32-bit).  (Although that commit
suggested we might fix it in time for 2.5, we ran out of time;
fortunately, it is unlikely enough to bite that it was not
worth worrying about during the 2.5 release.)

This fixes things by documenting the internal contracts, and
explaining why the internal function can return NULL and only
the public facing interface needs to worry about qnull(),
thus avoiding over-referencing the qnull_ global object.

It does not, however, fix the stupidity of the stack mixing
up two separate pieces of information; add a FIXME to explain
that issue, which will be fixed shortly in a future patch.

225d50fbb1 cpus: use broadcast on qemu_pause_cond
Jiri saw a hang on pause_all_vcpus called from postcopy_start,
where the cpus are all apparently stopped ('stopped' flag set)
but pause_all_vcpus is still stuck on a cond_wait on qemu_paused_cond.
We suspect this is happening if a qmp_stop is called at about the
same time as the postcopy code calls that pause_all_vcpus;
although they both should have the main lock held, Paolo spotted
the cond_wait unlocks the global lock so perhaps they both
could end up waiting at the same time?

blk_dev_is_tray_open() always returned false for them and the

Fix this by making blockdev-{insert,remove}-medium work on tray-less

invoked on such devices, and blk_dev_change_media_cb() is instead
called by blockdev-{insert,remove}-medium (for tray-less devices only).

d4aed70099 target-ppc: kvm: fix floating point registers sync on little-endian hosts
On VSX capable CPUs, the 32 FP registers are mapped to the high-bits
of the 32 first VSX registers. So if you have:

VSR31 = (uint128) 0x0102030405060708090a0b0c0d0e0f00

then

FPR31 = (uint64) 0x0102030405060708

The kernel stores the VSX registers in the fp_state struct following the
host endian element ordering.

On big-endian:

fp_state.fpr[31][0] = 0x0102030405060708
fp_state.fpr[31][1] = 0x090a0b0c0d0e0f00

On little-endian:

fp_state.fpr[31][0] = 0x090a0b0c0d0e0f00
fp_state.fpr[31][1] = 0x0102030405060708

The KVM_GET_ONE_REG and KVM_SET_ONE_REG ioctls preserve this ordering, but
QEMU considers it as big-endian and always copies element [0] to the
fpr[] array and element [1] to the vsr[] array. This does not work with
little-endian hosts, and you will get:

(qemu) p $f31
0x90a0b0c0d0e0f00

instead of:

(qemu) p $f31
0x102030405060708

This patch fixes the element ordering for little-endian hosts.

42ae4a3c61 net: vmxnet3: avoid memory leakage in activate_device
Vmxnet3 device emulator does not check if the device is active
before activating it, also it did not free the transmit & receive
buffers while deactivating the device, thus resulting in memory
leakage on the host. This patch fixes both these issues to avoid
host memory leakage.

0d335804e3 ehci: make idt processing more robust
Make ehci_process_itd return an error in case we didn't do any actual
iso transfer because we've found no active transaction.  That'll avoid
ehci happily run in circles forever if the guest builds a loop out of
idts.

This is CVE-2015-8558.

- It is the QEMU coding style.
3. Naming
@@ -116,62 +110,3 @@ if (a == 1) {
Rationale: Yoda conditions (as in 'if (1 == a)') are awkward to read.
Besides, good compilers already warn users when '==' is mis-typed as '=',
even when the constant is on the right.
7. Comment style
We use traditional C-style /* */ comments and avoid // comments.
Rationale: The // form is valid in C99, so this is purely a matter of
consistency of style. The checkpatch script will warn you about this.
Multiline comment blocks should have a row of stars on the left,
and the initial /* and terminating */ both on their own lines:
/*
* like
* this
*/
This is the same format required by the Linux kernel coding style.
(Some of the existing comments in the codebase use the GNU Coding
Standards form which does not have stars on the left, or other
variations; avoid these when writing new comments, but don't worry
about converting to the preferred form unless you're editing that
comment anyway.)
Rationale: Consistency, and ease of visually picking out a multiline
comment from the surrounding code.
8. trace-events style
8.1 0x prefix
In trace-events files, use a '0x' prefix to specify hex numbers, as in:
some_trace(unsigned x, uint64_t y) "x 0x%x y 0x" PRIx64
An exception is made for groups of numbers that are hexadecimal by
convention and separated by the symbols '.', '/', ':', or ' ' (such as
PCI bus id):
another_trace(int cssid, int ssid, int dev_num) "bus id: %x.%x.%04x"
However, you can use '0x' for such groups if you want. Anyway, be sure that
it is obvious that numbers are in hex, ex.:
data_dump(uint8_t c1, uint8_t c2, uint8_t c3) "bytes (in hex): %02x %02x %02x"
Rationale: hex numbers are hard to read in logs when there is no 0x prefix,
especially when (occasionally) the representation doesn't contain any letters
and especially in one line with other decimal numbers. Number groups are allowed
to not use '0x' because for some things notations like %x.%x.%x are used not
only in Qemu. Also dumping raw data bytes with '0x' is less readable.
8.2 '#' printf flag
Do not use printf flag '#', like '%#x'.
Rationale: there are two ways to add a '0x' prefix to printed number: '0x%...'
and '%#...'. For consistency the only one way should be used. Arguments for
'0x%' are:
- it is more popular
- '%#' omits the 0x for the value 0 which makes output inconsistent

In addition, QEMU assumes that the compiler does not use the latitude
given in C99 and C11 to treat aspects of signed '<<' as undefined, as
documented in the GNU Compiler Collection manual starting at version 4.0.
7. Error handling and reporting
7.1 Reporting errors to the human user
Do not use printf(), fprintf() or monitor_printf(). Instead, use
error_report() or error_vreport() from error-report.h. This ensures the
error is reported in the right place (current monitor or stderr), and in
a uniform format.
Use error_printf() & friends to print additional information.
error_report() prints the current location. In certain common cases
like command line parsing, the current location is tracked
automatically. To manipulate it manually, use the loc_*() from
error-report.h.
7.2 Propagating errors
An error can't always be reported to the user right where it's detected,
but often needs to be propagated up the call chain to a place that can
handle it. This can be done in various ways.
The most flexible one is Error objects. See error.h for usage
information.
Use the simplest suitable method to communicate success / failure to
callers. Stick to common methods: non-negative on success / -1 on
error, non-negative / -errno, non-null / null, or Error objects.
Example: when a function returns a non-null pointer on success, and it
can fail only in one way (as far as the caller is concerned), returning
null on failure is just fine, and certainly simpler and a lot easier on
the eyes than propagating an Error object through an Error ** parameter.
Example: when a function's callers need to report details on failure
only the function really knows, use Error **, and set suitable errors.
Do not report an error to the user when you're also returning an error
for somebody else to handle. Leave the reporting to the place that
consumes the error returned.
7.3 Handling errors
Calling exit() is fine when handling configuration errors during
startup. It's problematic during normal operation. In particular,
monitor commands should never exit().
Do not call exit() or abort() to handle an error that can be triggered
by the guest (e.g., some unimplemented corner case in guest code
translation or device emulation). Guests should not be able to
terminate QEMU.
Note that &error_fatal is just another way to exit(1), and &error_abort
is just another way to abort().

A 'git-publish' utility was created to make above process less
cumbersome, and is highly recommended for making regular contributions,
or even just for sending consecutive patch series revisions. It also
requires a working 'git send-email' setup, and by default doesn't
automate everything, so you may want to go through the above steps
manually for once.
For installation instructions, please go to
https://github.com/stefanha/git-publish
The workflow with 'git-publish' is:
$ git checkout master -b my-feature
$ # work on new commits, add your 'Signed-off-by' lines to each
$ git publish
Your patch series will be sent and tagged as my-feature-v1 if you need to refer
back to it in the future.
Sending v2:
$ git checkout my-feature # same topic branch
$ # making changes to the commits (using 'git rebase', for example)
$ git publish
Your patch series will be sent with 'v2' tag in the subject and the git tip
will be tagged as my-feature-v2.
