Max Reitz 86d1bd7098 block/parallels: Avoid overflows
Change the types of variables in allocate_clusters() to int64_t so we do
not have to worry about potential overflows.

Add an assertion that our accesses to s->bat[] do not result in a buffer
overflow and that the implicit conversion performed when invoking
bat_entry_off() does not result in an integer overflow.

Eric Blake f82c5b17ea iotests: Improve image-clear tests on non-aligned image
Tweak 097 and 176 to operate on an image that is not cluster-aligned,
to give further coverage of clearing out an entire image, including
the recent fix to eliminate the difference between fast path (97) and
slow (176) for qcow2.  Also tested on qcow (97 only, since qcow lacks
snapshots).

Eric Blake 0c1bd4692f qcow2: Discard unaligned tail when wiping image
There is a subtle difference between the fast (qcow2v3 with no
extra data) and slow path (qcow2v2 format [aka 0.10], or when a
snapshot is present) of qcow2_make_empty().  The slow path fails
to discard the final (partial) cluster of an unaligned image.

The problem stems from the fact that qcow2_discard_clusters() was
silently ignoring sub-cluster head and tail on unaligned requests.
A quick audit of all callers shows that qcow2_snapshot_create() has
always passed a cluster-aligned request since the call was added
in commit 1ebf561; qcow2_co_pdiscard() has passed a cluster-aligned
request since commit ecdbead taught the block layer about preferred
discard alignment; and qcow2_make_empty() was fixed to pass an
aligned start (but not necessarily end) in commit a3e1505.

Asserting that the start is always aligned also points out that we
now have a dead check: rounding the end offset down can never result
in a value less than the aligned start offset (the check was rendered
dead with commit ecdbead).  Meanwhile, we do not want to round the
end cluster down in the one case of the end offset matching the
(unaligned) file size - that final partial cluster should still be
discarded.

With those fixes in place, the fast and slow paths are back in sync
at discarding an entire image; the next patch will update
qemu-iotests to ensure we don't regress.

Note that bdrv_co_pdiscard ignores ALL partial cluster requests,
including the partial cluster at the end of an image; it can be
argued that the partial cluster at the end should be special-cased
so that a guest issuing discard requests at proper alignments
everywhere else can likewise empty the entire image.  But that
optimization is left for another day.

Daniel P. Berrange 07ff948bd1 iotests: fix 097 when run with qcow
The previous commit:

  commit a3e1505dae
  Author: Eric Blake <eblake@redhat.com>
  Date:   Mon Dec 5 09:49:34 2016 -0600

    qcow2: Don't strand clusters near 2G intervals during commit

extended the 097 test case so that it did two passes, once
with an internal snapshot, once without.

qcow (v1) does not support internal snapshots, so this change
broke test 097 when run against qcow.

This splits 097 in two, creating a new 176 that tests the
internal snapshot codepath, effectively putting 097 back
to its content before the above commit.

Peter Maydell 6aabeb5839 qemu-io-cmds: Assert that global and nofile commands don't use ct->perms
It would be a bug for a command with the CMD_NOFILE_OK or
CMD_FLAG_GLOBAL flags set to also set the ct->perms field,
because the former says "OK for a file not to be open"
but the latter is a check on a file.

Add an assertion in qemuio_add_command() so we can catch that
sort of buggy command definition immediately rather than it
being a bug that only manifests when a particular set of
command line options is used.

(Coverity gets confused about this (CID 1371723) and reports
that we might dereference a NULL blk pointer in this case,
because it can't tell that that code path never happens with
the cmdinfo_t that we have. This commit won't help unconfuse
it, but it does fix the underlying issue.)

Markus Armbruster d1c136885b sheepdog: Fix blockdev-add
Commit 831acdc "sheepdog: Implement bdrv_parse_filename()" and commit
d282f34 "sheepdog: Support blockdev-add" have different ideas on how
the QemuOpts parameters for the server address are named.  Fix that.
While there, rename BlockdevOptionsSheepdog member addr to server, for
consistency with BlockdevOptionsSsh, BlockdevOptionsGluster,
BlockdevOptionsNbd.

Commit 831acdc's example becomes

    --drive driver=sheepdog,server.type=inet,server.host=fido,server.port=7000,vdi=dolly

instead of

    --drive driver=sheepdog,host=fido,vdi=dolly

Markus Armbruster 9445673ea6 nbd: Tidy up blockdev-add interface
SocketAddress is a simple union, and simple unions are awkward: they
have their variant members wrapped in a "data" object on the wire, and
require additional indirections in C.  I intend to limit its use to
existing external interfaces, and convert all internal interfaces to
SocketAddressFlat.

BlockdevOptionsNbd is an external interface using SocketAddress.  We
already use SocketAddressFlat elsewhere in blockdev-add.  Replace it
by SocketAddressFlat while we can (it's new in 2.9) for simplicity and
consistency.  For example,

    { "execute": "blockdev-add",
      "arguments": { "node-name": "foo", "driver": "nbd",
                     "server": { "type": "inet",
		                 "data": { "host": "localhost",
				           "port": "12345" } } } }

becomes

    { "execute": "blockdev-add",
      "arguments": { "node-name": "foo", "driver": "nbd",
                     "server": { "type": "inet",
		                 "host": "localhost", "port": "12345" } } }

Since the internal interfaces still take SocketAddress, this requires
conversion function socket_address_crumple().  It'll go away when I
update the interfaces.

Unfortunately, SocketAddress is also visible in -drive since 2.8:

    -drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345

Nobody should be using it, as it's fairly new and has never been
documented, so adding still more compatibility gunk to keep it working
isn't worth the trouble.  You now have to use

    -drive if=none,driver=nbd,server.type=inet,server.host=127.0.0.1,server.port=12345

[mreitz: Change iotest 147 accordingly]

Because of this interface change, iotest 147 has to be adapted.
Unfortunately, we cannot just flatten all of the addresses because
nbd-server-start still takes a plain SocketAddress. Therefore, we need
both and this is most easily achieved by writing the SocketAddress into
the code and flattening it where necessary.

Markus Armbruster 129c7d1c53 block: Document -drive problematic code and bugs
-blockdev and blockdev_add convert their arguments via QObject to
BlockdevOptions for qmp_blockdev_add(), which converts them back to
QObject, then to a flattened QDict.  The QDict's members are typed
according to the QAPI schema.

-drive converts its argument via QemuOpts to a (flat) QDict.  This
QDict's members are all QString.

Thus, the QType of a flat QDict member depends on whether it comes
from -drive or -blockdev/blockdev_add, except when the QAPI type maps
to QString, which is the case for 'str' and enumeration types.

The block layer core extracts generic configuration from the flat
QDict, and the block driver extracts driver-specific configuration.

Both commonly do so by converting (parts of) the flat QDict to
QemuOpts, which turns all values into strings.  Not exactly elegant,
but correct.

However, A few places access the flat QDict directly:

* Most of them access members that are always QString.  Correct.

* bdrv_open_inherit() accesses a boolean, carefully.  Correct.

* nfs_config() uses a QObject input visitor.  Correct only because the
  visited type contains nothing but QStrings.

* nbd_config() and ssh_config() use a QObject input visitor, and the
  visited types contain non-QStrings: InetSocketAddress members
  @numeric, @to, @ipv4, @ipv6.  -drive works as long as you don't try
  to use them (they're all optional).  @to is ignored anyway.

  Reproducer:
  -drive driver=ssh,server.host=h,server.port=22,server.ipv4,path=p
  -drive driver=nbd,server.type=inet,server.data.host=h,server.data.port=22,server.data.ipv4
  both fail with "Invalid parameter type for 'data.ipv4', expected: boolean"

Add suitable comments to all these places.  Mark the buggy ones FIXME.

"Fortunately", -drive's driver-specific options are entirely
undocumented.

we could end up storing incorrect values to guest memory.
(In particular the i386 guest BIOS would crash on startup.)

Add code to the trampolines that call the store helpers to
do the zero extension as required.

MemoryRegionCache did not know about virtio support for IOMMUs (because the
two features were developed at the same time).  Revert MemoryRegionCache
to "normal" address_space_* operations for 2.9, as it is simpler than

Javier Celaya 1684907c92 Fix input-linux reading from device
The evdev devices in input-linux.c are read in blocks of one whole
event. If there are not enough bytes available, they are discarded,
instead of being kept for the next read operation. This results in
lost events, of even non-working devices.

This patch keeps track of the number of bytes to be read to fill up
a whole event, and then handle it.

Changes from v1 to v2:
- Fix: Calculate offset on each iteration

Changes from v2 to v3:
- Fix coding style
- Store offset instead of bytes to be read

Gerd Hoffmann 243afe858b xhci: flush dequeue pointer to endpoint context
When done processing a endpoint ring we must update the dequeue pointer
in the endpoint context in guest memory.  This is needed to make sure
the guest has a correct view of things and also to make live migration
work properly, because xhci post_load restores alot of the state from
xhci data structures in guest memory.

Add xhci_set_ep_state() call to do that.

The recursive calls stopped by commit
ddb603ab6c had the (unintentional) side
effect to hiding this bug.  xhci_set_ep_state() was called before
processing, to set the state to running, which updated the dequeue
pointer too.

David Gibson 8149e2992f pseries: Enforce homogeneous threads-per-core
For reasons that may be useful in future, CPU core objects, as used on the
pseries machine type have their own nr-threads property, potentially
allowing cores with different numbers of threads in the same system.

If the user/management uses the values specified in query-hotpluggable-cpus
as they're expected to do, this will never matter in pratice.  But that's
not actually enforced - it's possible to manually specify a core with
a different number of threads from that in -smp.  That will confuse the
platform - most immediately, this can be used to create a CPU thread with
index above max_cpus which leads to an assertion failure in
spapr_cpu_core_realize().

For now, enforce that all cores must have the same, standard, number of
threads.

Eric Blake e98c6961c8 rbd: Fix regression in legacy key/values containing escaped :
Commit c7cacb3 accidentally broke legacy key-value parsing through
pseudo-filename parsing of -drive file=rbd://..., for any key that
contains an escaped ':'.  Such a key is surprisingly common, thanks
to mon_host specifying a 'host:port' string.  The break happens
because passing things from QDict through QemuOpts back to another
QDict requires that we pack our parsed key/value pairs into a string,
and then reparse that string, but the intermediate string that we
created ("key1=value1:key2=value2") lost the \: escaping that was
present in the original, so that we could no longer see which : were
used as separators vs. those used as part of the original input.

Fix it by collecting the key/value pairs through a QList, and
sending that list on a round trip through a JSON QString (as in
'["key1","value1","key2","value2"]') on its way through QemuOpts,
rather than hand-rolling our own string.  Since the string is only
handled internally, this was faster than creating a full-blown
struct of '[{"key1":"value1"},{"key2":"value2"}]', and safer at
guaranteeing order compared to '{"key1":"value1","key2":"value2"}'.

It would be nicer if we didn't have to round-trip through QemuOpts
in the first place, but that's a much bigger task for later.

Reproducer:
./x86_64-softmmu/qemu-system-x86_64 -nodefaults -nographic -qmp stdio \
-drive 'file=rbd:volumes/volume-ea141b5c-cdb3-4765-910d-e7008b209a70'\
':id=compute:key=AQAVkvxXAAAAABAA9ZxWFYdRmV+DSwKr7BKKXg=='\
':auth_supported=cephx\;none:mon_host=192.168.1.2\:6789'\
',format=raw,if=none,id=drive-virtio-disk0,'\
'serial=ea141b5c-cdb3-4765-910d-e7008b209a70,cache=writeback'

Even without an RBD setup, this serves a test of whether we get
the incorrect parser error of:
qemu-system-x86_64: -drive file=rbd:...cache=writeback: conf option 6789 has no value
or the correct behavior of hanging while trying to connect to
the requested mon_host of 192.168.1.2:6789.

The original patch intend to prevent linux i915 driver from using
stolen meory. But this patch breaks windows IGD driver loading on
Gen9+, as IGD HW will use stolen memory on Gen9+, once windows IGD
driver see zero size stolen memory, it will unload.
Meanwhile stolen memory will be disabled in 915 when i915 run as
a guest.

Michael Roth 8251a72f8b qga: don't fail if mount doesn't have slave devices
In some cases the slave devices of a virtual block device are tracked
by the parent in the corresponding sysfs node. For instance, if we
have a loop-back mount of the form:

  /dev/loop3p1 on /home/mdroth/mnt type ext4 (rw,relatime,data=ordered)

this will be reflected in sysfs as:

  /sys/devices/virtual/block/loop3/
  ...
  /sys/devices/virtual/block/loop3/slaves
  /sys/devices/virtual/block/loop3/loop3p1

The current code however assumes the mounted virtual block device,
loop3p1 in this case, contains the slaves directory, and reports an
error otherwise. This breaks 'make check' in certain environments.

Fix this by simply skipping attempts to generate disk topology
information in these cases. Since this information is documented
in QAPI as optionally-reported, this should be ok from an API
perspective.

In the future, this can possibly be improved upon by collecting
topology information from the parent in these cases.

Michael S. Tsirkin 0d876080a3 tests/acpi: don't pack a structure
There's no reason to pack structures where we don't care about size or
padding, this applies to AcpiStdTable in tests/acpi-utils.h.

OTOH bios-tables-test happens to be passing the address of a field in
this  struct to a function that expects a pointer to normally aligned
data which results in a SIGBUS on architectures like SPARC that have
strict alignment requirements.

Jason Wang 375f74f473 vhost: generalize iommu memory region
We assumes the iommu_ops were attached to the root region of address
space. This may not be true for all kinds of IOMMU implementation and
especially after commit 3716d5902d ("pci: introduce a bus master
container"). So fix this by not assuming as->root has iommu_ops,
instead depending on the regions reported by memory listener through:

- register a memory listener to dma_as
- during region_add, if it's a region of IOMMU, register a specific
  IOMMU notifier, and store all notifiers in a list.
- during region_del, compare and delete the IOMMU notifier from the list

This is also a must for making vhost device IOTLB works for all types
of IOMMUs. Note, since we register one notifier during each
.region_add, the IOTLB may be flushed more than one times, this is
suboptimal and could be optimized in the future.
