Paolo Bonzini 5aaac46793 migration: savevm: consult migration blockers
There is really no difference between live migration and savevm, except
that savevm does not require bdrv_invalidate_cache to be implemented
by all disks.  However, it is unlikely that savevm is used with anything
except qcow2 disks, so the penalty is small and worth the improvement
in catching bad usage of savevm.

Only one place was taking care of savevm when adding a migration blocker,
and it can be removed.

George Kennedy 56333e69ee lsi: Reselection needed to remove pending commands from queue
Under heavy IO (e.g. fio) the queue is not checked frequently enough for
pending commands. As a result some pending commands are timed out by the
linux sym53c8xx driver, which sends SCSI Abort messages for the timed out
commands. The SCSI Abort messages result in linux errors, which show up
on the console and in /var/log/messages.

e.g.
sd 0:0:3:0: [sdd] tag#33 ABORT operation started
scsi target0:0:3: control msgout:
80 20 47 d
sd 0:0:3:0: ABORT operation complete.
scsi target0:0:4: message d sent on bad reselection

Now following a WAIT DISCONNECT Script instruction, and if there is no
current command, check for a pending command on the queue and if one
exists call lsi_reselect().

Paolo Bonzini a8efa60633 cpus: run work items for all vCPUs if single-threaded
This avoids the following I/O thread deadlock:

1) the I/O thread calls run_on_cpu for CPU 3 from a timer.  single_tcg_halt_cond
is signaled

2) CPU 1 is running and exits.  It finds no work item and enters CPU 2

3) because the I/O thread is stuck in run_on_cpu, the round-robin kick
timer never triggers, and CPU 3 never runs the work item

4) run_on_cpu never completes

Nested SVM only does not support it, but unfortunately it is

Gerd Hoffmann e1ca8f7e19 qapi: add query-display-options command
Add query-display-options command, which allows querying the qemu
display configuration.  This isn't particularly useful, except it
exposes QAPI type DisplayOptions in query-qmp-schema, so that libvirt
can discover recently added -display parameter rendernode (commit
d4dc4ab133).  Works around lack of sufficiently powerful command line
introspection.

A check for scan_enabled has been added to ps2_keyboard_event in commit

This works well as long as operating system is resetting keyboard, or enabling it.

KBD_CMD_ENABLE or KBD_CMD_RESET_ENABLE before trying to use the keyboard.

Greg Kurz 1d20398694 9p: fix QEMU crash when renaming files
When using the 9P2000.u version of the protocol, the following shell
command line in the guest can cause QEMU to crash:

    while true; do rm -rf aa; mkdir -p a/b & touch a/b/c & mv a aa; done

With 9P2000.u, file renaming is handled by the WSTAT command. The
v9fs_wstat() function calls v9fs_complete_rename(), which calls
v9fs_fix_path() for every fid whose path is affected by the change.
The involved calls to v9fs_path_copy() may race with any other access
to the fid path performed by some worker thread, causing a crash like
shown below:

Thread 12 "qemu-system-x86" received signal SIGSEGV, Segmentation fault.

The fix is to take the path write lock when calling v9fs_complete_rename(),
like in v9fs_rename().

Alberto Garcia 6bd858b311 block: Update BlockDriverState.inherits_from on bdrv_drop_intermediate()
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.

Alberto Garcia 0065c455f9 block: Update BlockDriverState.inherits_from on bdrv_set_backing_hd()
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.

Logan Gunthorpe ad3a7e4555 nvme: fix bug with PCI IRQ pins on teardown
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.

Paolo Bonzini 87ad860c62 nvme: fix out-of-bounds access to the CMB
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.

unfinished will lockup or crash as their SG structures being potentially
reused. Call blk_drain before freeing the queues to avoid this nasty
scenario.

Daniel P. Berrangé e4c8f2925d iotests: fix nbd test 233 to work correctly with raw images
The first qemu-io command must honour the $IMGFMT that is set rather
than hardcoding qcow2. The qemu-nbd commands should also set $IMGFMT
to avoid the insecure format probe warning.

Richard W.M. Jones 1c7f618f68 scsi-disk: Fix crash if underlying host file or disk returns error
Commit 40dce4ee6 "scsi-disk: fix rerror/werror=ignore" introduced a
bug which causes qemu to crash with the assertion error below if the
host file or disk returns an error:

  qemu-system-x86_64: hw/scsi/scsi-bus.c:1374: scsi_req_complete:
  Assertion `req->status == -1' failed.

Kevin Wolf suggested this fix:

  < kwolf> Hm, should the final return false; in that patch
           actually be a return true?
  < kwolf> Because I think he didn't intend to change anything
           except BLOCK_ERROR_ACTION_IGNORE

Eric Blake 155af09d44 iotests: Skip 233 if certtool not installed
The use of TLS while building qemu is optional. While the
'certtool' binary should be available on every platform that
supports building against TLS, that does not imply that the
developer has installed it.  Make the test gracefully skip
in that case.

Kevin Wolf fa1cfb4026 iotests: Replace assertEquals() with assertEqual()
TestCase.assertEquals() is deprecated since Python 2.7. Recent Python
versions print a warning when the function is called, which makes test
cases fail.

Replace it with the preferred spelling assertEqual().
