fdc/i8257: implement verify transfer mode
While working on the Tulip driver i tried to write some Teledisk images to
a floppy image which didn't work. Turned out that Teledisk checks the written
data by issuing a READ command to the FDC but running the DMA controller
in VERIFY mode. As we ignored the DMA request in that case, the DMA transfer
never finished, and Teledisk reported an error.
The i8257 spec says about verify transfers:
3) DMA verify, which does not actually involve the transfer of data. When an
8257 channel is in the DMA verify mode, it will respond the same as described
for transfer operations, except that no memory or I/O read/write control signals
will be generated.
Hervé proposed to remove all the dma_mode_ok stuff from fdc to have a more
clear boundary between DMA and FDC, so this patch also does that.

qemu-img: Fix check's leak/corruption fix report
There are two problems with qemu-img check's report on how many leaks
and/or corruptions have been fixed:
(1) ImageCheck.has_leaks_fixed and ImageCheck.has_corruptions_fixed are
only true when ImageCheck.leaks or ImageCheck.corruptions (respectively)
are non-zero. qcow2's check implementation will set the latter to zero
after it has fixed leaks and corruptions, though, so leaks-fixed and
corruptions-fixed are actually never reported after successful repairs.
We should always report them when they are non-zero, just like all the
other fields of ImageCheck.
(2) After something has been fixed and we run the check a second time,
leaks_fixed and corruptions_fixed are taken from the first run; but
has_leaks_fixed and has_corruptions_fixed are not. The second run
actually cannot fix anything, so with (1) fixed, has_leaks_fixed and
has_corruptions_fixed will always be false here. (With (1) unfixed,
they will at least be false on successful runs, because then the number
of leaks and corruptions found in the second run should be 0.)
We should save has_leaks_fixed and has_corruptions_fixed just like we
save leaks_fixed and corruptions_fixed.

to emit this optional header in images with small cluster sizes.

fallback, just implement the .bdrv_co_create_opts in the drivers that

This way we don't break various places that need to know if the
underlying protocol/format really supports image creation, and this way
we still allow some drivers to not support image creation.

vl.c: fix migration failure for 3.1 and older machine types
Migration from QEMU(v4.0) fails when using 3.1 or older machine
type. For example if one attempts to migrate
QEMU-2.12 started as
qemu-system-ppc64 -nodefaults -M pseries-2.12 -m 4096 -mem-path /tmp/
to current master, it will fail with
qemu-system-ppc64: Unknown ramblock "ppc_spapr.ram", cannot accept migration
qemu-system-ppc64: error while loading state for instance 0x0 of device 'ram'
qemu-system-ppc64: load of migration failed: Invalid argument
Caused by
900c0ba373 commit which switches main RAM allocation to
memory backends and the fact in 3.1 and older QEMU, backends used
full[***] QOM path as memory region name instead of backend's name.
That was changed after 3.1 to use prefix-less names by default
(
fa0cb34d22) for new machine types.
*** effectively makes main RAM memory region names defined by
MachineClass::default_ram_id being altered with '/objects/' prefix
and therefore migration fails as old QEMU sends prefix-less
name while new QEMU expects name with prefix when using 3.1 and
older machine types.
Fix it by forcing implicit[1] memory backend to always use
prefix-less names for its memory region by setting
'x-use-canonical-path-for-ramblock-id'
property to false.
1) i.e. memory backend created by compat glue which maps
-m/-mem-path/-mem-prealloc/default RAM size into
appropriate backend type/options to match old CLI format.

Per David Gilbert, "it could just be the writing is slow on s390

Tuning the threshold by reducing the initial bandwidth makes the

qga-win: prevent crash when executing guest-file-read with large count
guest-file-read command is currently implemented to read from a
file handle count number of bytes. when executed with a very large count number
qemu-ga crashes.
after some digging turns out that qemu-ga crashes after trying to allocate
a buffer large enough to save the data read in it, the buffer was allocated using
g_malloc0 which is not fail safe, and results a crash in case of failure.
g_malloc0 was replaced with g_try_malloc0() which returns NULL on failure,
A check was added for that case in order to prevent qemu-ga from crashing
and to send a response to the qemu-ga client accordingly.

calling them. This is the case already for the callsites in
kvmppc_handle_dcr_read/write(), but we must also take the lock when
calling the helpers from TCG.

target/ppc: Fix slbia TLB invalidation gap
slbia must invalidate TLBs even if it does not remove a valid SLB
entry, because slbmte can overwrite valid entries without removing
their TLBs.
As the architecture says, slbia invalidates all lookaside information,
not conditionally based on if it removed valid entries.
It does not seem possible for POWER8 or earlier Linux kernels to hit
this bug because it never changes its kernel SLB translations, and it
should always have valid entries if any accesses are made to userspace
regions. However other operating systems which may modify SLB entry 0
or do more fancy things with segments might be affected.
When POWER9 slbia support is added in the next patch, this becomes a
real problem because some new slbia variants don't invalidate all
non-zero entries.

python/qemu: Kill QEMU process if 'quit' doesn't work
With a QEMU bug, it can happen that the QEMU process doesn't react to a
'quit' QMP command. If we got an exception during previous QMP
communication (e.g. iotests Timeout expiring), we could also be in an
inconsistent state where after sending 'quit' we immediately read an old
response and close the socket even though the 'quit' command wasn't
processed yet. Both cases would lead to a hanging test.
Fix this by waiting for the QEMU process to exit after sending 'quit'
with a timeout, and if it doesn't happen within three seconds, send
SIGKILL.

hw/rdma: Skip data-path mr_id translation
With the change made in commit
68b89aee71 ("Utilize ibv_reg_mr_iova for
memory registration") the MR emulation is no longer needed in order to
translate the guest addresses into host addresses.
With that, the next obvious step is to skip entirely the processing in
data-path.
To accomplish this, return the backend's lkey to driver so we will not
need to do the emulated mr_id to backend mr_id translation in data-path.
The function build_host_sge_array is still called in data-path but only
for backward computability with statistics collection.
While there, as a cosmetic change to make the code cleaner - make one
copy of the function rdma_backend_create_mr and leave the redundant
guest_start argument in the legacy code.
