The previous patch fixed the inherits_from pointer after block-stream,
and this one does the same for block-commit.
When block-commit finishes and the 'top' node is not the topmost one
from the backing chain then all nodes above 'base' up to and including
'top' are removed from the chain.
The bdrv_drop_intermediate() call converts a chain like this one:
base <- intermediate <- top <- active
into this one:
base <- active
In a simple scenario each backing file from the first chain has the
inherits_from attribute pointing to its parent. This means that
reopening 'active' will recursively reopen all its children, whose
options can be changed in the process.
However after the 'block-commit' call base.inherits_from is NULL and
the chain is broken, so 'base' does not inherit from 'active' and will
not be reopened automatically:
$ qemu-img create -f qcow2 hd0.qcow2 1M
$ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
$ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2
$ $QEMU -drive if=none,file=hd2.qcow2
{ 'execute': 'block-commit',
'arguments': {
'device': 'none0',
'top': 'hd1.qcow2' } }
{ 'execute': 'human-monitor-command',
'arguments': {
'command-line':
'qemu-io none0 "reopen -o backing.l2-cache-size=2M"' } }
{ "return": "Cannot change the option 'backing.l2-cache-size'\r\n"}
This patch updates base.inherits_from in this scenario, and adds a
test case.

When a BlockDriverState's child is opened (be it a backing file, the
protocol layer, or any other) inherits_from is set to point to the
parent node. Children opened separately and then attached to a parent
don't have this pointer set.
bdrv_reopen_queue_child() uses this to determine whether a node's
children must also be reopened inheriting the options from the parent
or not. If inherits_from points to the parent then the child is
reopened and its options can be changed, like in this example:
$ qemu-img create -f qcow2 hd0.qcow2 1M
$ qemu-img create -f qcow2 hd1.qcow2 1M
$ $QEMU -drive if=none,node-name=hd0,file=hd0.qcow2,\
backing.driver=qcow2,backing.file.filename=hd1.qcow2
(qemu) qemu-io hd0 "reopen -o backing.l2-cache-size=2M"
If the child does not inherit from the parent then it does not get
reopened and its options cannot be changed:
$ $QEMU -drive if=none,node-name=hd1,file=hd1.qcow2
-drive if=none,node-name=hd0,file=hd0.qcow2,backing=hd1
(qemu) qemu-io hd0 "reopen -o backing.l2-cache-size=2M"
Cannot change the option 'backing.l2-cache-size'
If a disk image has a chain of backing files then all of them are also
connected through their inherits_from pointers (i.e. it's possible to
walk the chain in reverse order from base to top).
However this is broken if the intermediate nodes are removed using
e.g. block-stream because the inherits_from pointer from the base node
becomes NULL:
$ qemu-img create -f qcow2 hd0.qcow2 1M
$ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
$ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2
$ $QEMU -drive if=none,file=hd2.qcow2
(qemu) qemu-io none0 "reopen -o backing.l2-cache-size=2M"
(qemu) block_stream none0 0 hd0.qcow2
(qemu) qemu-io none0 "reopen -o backing.l2-cache-size=2M"
Cannot change the option 'backing.l2-cache-size'
This patch updates the inherits_from pointer if the intermediate nodes
of a backing chain are removed using bdrv_set_backing_hd(), and adds a
test case for this scenario.

When the submission and completion queues are being torn down
the IRQ will be asserted for the completion queue when the
submsission queue is deleted. Then when the completion queue
is deleted it stays asserted. Thus, on systems that do
not use MSI, no further interrupts can be triggered on the host.
Linux sees this as a long delay when unbinding the nvme device.
Eventually the interrupt timeout occurs and it continues.
To fix this we ensure we deassert the IRQ for a CQ when it is

Because the CMB BAR has a min_access_size of 2, if you read the last

error. This is CVE-2018-16847.
Another way to fix this might be to register the CMB as a RAM memory
region, which would also be more efficient. However, that might be a
change for big-endian machines; I didn't think this through and I don't
know how real hardware works. Add a basic testcase for the CMB in case
somebody does this change later on.

It turns out that the same can happen at several locations where
v9fs_path_copy() is used to set the fid path. The fix is again to

GNUTLS takes a paranoid approach when seeing 0 bytes returned by the
underlying OS read() function. It will consider this an error and
return GNUTLS_E_PREMATURE_TERMINATION instead of propagating the 0
return value. It expects apps to arrange for clean termination at
the protocol level and not rely on seeing EOF from a read call to
detect shutdown. This is to harden apps against a malicious 3rd party
causing termination of the sockets layer.
This is unhelpful for the QEMU NBD code which does have a clean
protocol level shutdown, but still relies on seeing 0 from the I/O
channel read in the coroutine handling incoming replies.
The upshot is that when using a plain NBD connection shutdown is
silent, but when using TLS, the client spams the console with
Cannot read from TLS channel: Broken pipe
The NBD connection has, however, called qio_channel_shutdown()
at this point to indicate that it is done with I/O. This gives
the opportunity to optimize the code such that when the channel
has been shutdown in the read direction, the error code
GNUTLS_E_PREMATURE_TERMINATION gets turned into a '0' return
instead of an error.

Running
git grep '\$here' tests/qemu-iotests
has 0 hits, which means we are setting a variable that has
no use. It appears that commit e8f8624d removed the last
use. So execute the following cmd to remove all of
the 'here=...' lines as dead code.
sed -i '/^here=/d' $(git grep -l '^here=' tests/qemu-iotests)

In practice for most of the more-or-less orphan Arm board models,
I will review patches and put them in via the target-arm tree.
So list myself as an "Odd Fixes" status maintainer for them.
This commit downgrades these boards to "Odd Fixes":
* Allwinner-A10
* Exynos
* Calxeda Highbank
* Canon DIGIC
* Musicpal
* nSeries
* Palm
* PXA2xx
These boards were already "Odd Fixes":
* Gumstix
* i.MX31 (kzm)
Philippe Mathieu-Daudé has requested to be moved to R:
status for Gumstix now that I am listed as the M: contact.
Some boards are maintained, but their patches still go
via the target-arm tree, so add myself as a secondary
maintainer contact for those:
* Xilinx Zynq
* Xilinx ZynqMP
* STM32F205
* Netduino 2
* SmartFusion2
* Mecraft M2S-FG484
* ASPEED BMCs
* NRF51

Update the onenand device to use qemu_log_mask() for reporting
guest errors and unimplemented features, rather than plain
fprintf() and hw_error().
(We leave the hw_error() in onenand_reset(), as that is
triggered by a failure to read the underlying block device
for the bootRAM, not by guest action.)

An off-by-one error in a switch case in onenand_read() allowed
a misbehaving guest to read off the end of a block of memory.
NB: the onenand device is used only by the "n800" and "n810"
machines, which are usable only with TCG, not KVM, so this is
not a security issue.

This commit fixes a case where the CPU would try to go to EL3 when
executing an smc instruction, even though ARM_FEATURE_EL3 is false. This
case is raised when the PSCI conduit is set to smc, but the smc
instruction does not lead to a valid PSCI call.
QEMU crashes with an assertion failure latter on because of incoherent
mmu_idx.
This commit refactors the pre_smc helper by enumerating all the possible
way of handling an scm instruction, and covering the previously missing
case leading to the crash.
The following minimal test would crash before this commit:
.global _start
.text
_start:
ldr x0, =0xdeadbeef ; invalid PSCI call
smc #0
run with the following command line:
aarch64-linux-gnu-gcc -nostdinc -nostdlib -Wl,-Ttext=40000000 \
-o test test.s
qemu-system-aarch64 -M virt,virtualization=on,secure=off \

The UART and timer devices for the stm32f205 were being created
with memory regions that were too large. Use the size specified
in the chip datasheet.
The old sizes were so large that the devices would overlap with
each other in the SoC memory map, so this fixes a bug that
caused odd behavior and/or crashes when trying to set up multiple
UARTs.

Add entries for the boards "mcimx6ul-evk", "mcimx7d-sabre", "raspi2",
"raspi3", "sabrelite", "vexpress-a15", "vexpress-a9" and "virt".
While we're at it, also adjust the "i.MX31" section a little bit,
so that the wildcards there do not match anymore for unrelated files
(e.g. the new hw/misc/imx6ul_ccm.c file).
