A check for scan_enabled has been added to ps2_keyboard_event in commit
143c04c7e0 to prevent stream corruption.
This works well as long as operating system is resetting keyboard, or enabling it.
This fixes IBM 40p firmware, which doesn't bother sending KBD_CMD_RESET,
KBD_CMD_ENABLE or KBD_CMD_RESET_ENABLE before trying to use the keyboard.

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
deleted.

Because the CMB BAR has a min_access_size of 2, if you read the last
byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
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.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Recent commit 5b76ef50f6 fixed a race where v9fs_co_open2() could
possibly overwrite a fid path with v9fs_path_copy() while it is being
accessed by some other thread, ie, use-after-free that can be detected
by ASAN with a custom 9p client.
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
take the write lock.

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.

Various shell files contain a mix between obsolete ``
and modern $(); It would be nice to convert to using
$() everywhere. For now, just do the qemu-iotests directory.

[eblake: tweak commit message]
Signed-off-by: Eric Blake <eblake@redhat.com>
POSIX requires $PWD to be reliable, and we expect all
shells used by qemu scripts to be relatively close to
POSIX. Thus, it is smarter to avoid forking the pwd
executable for something that is already available in
the environment.
So replace it with the following:
sed -i 's/\(`pwd`\|\$(pwd)\)/$PWD/g' $(git grep -l pwd)
Then delete a pointless line assigning PWD to itself.

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.
