hw/net/i82596.c: Avoid reading off end of buffer in i82596_receive()
The i82596_receive() function attempts to pass the guest a buffer
which is effectively the concatenation of the data it is passed and a
4 byte CRC value. However, rather than implementing this as "write
the data; then write the CRC" it instead bumps the length value of
the data by 4, and writes 4 extra bytes from beyond the end of the
buffer, which it then overwrites with the CRC. It also assumed that
we could always fit all four bytes of the CRC into the final receive
buffer, which might not be true if the CRC needs to be split over two
receive buffers.
Calculate separately how many bytes we need to transfer into the
guest's receive buffer from the source buffer, and how many we need
to transfer from the CRC work.
We add a count 'bufsz' of the number of bytes left in the source
buffer, which we use purely to assert() that we don't overrun.
Spotted by Coverity (CID
1419396) for the specific case when we end
up using a local array as the source buffer.

Raise ConfigError rather than VersionRequirementError when we detect
that the Python being used by Sphinx is too old.
Currently the way we flag the Python version problem up to the user
causes Sphinx to print an unnecessary Python stack trace as well as
the information about the problem; in most versions of Sphinx this is
unavoidable.
The upstream Sphinx developers kindly added a feature to allow
conf.py to report errors to the user without the backtrace:
https://github.com/sphinx-doc/sphinx/commit/
be608ca2313fc08eb842f3dc19d0f5d2d8227d08

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.

mirror: Wait only for in-flight operations
mirror_wait_for_free_in_flight_slot() just picks a random operation to
wait for. However, a MirrorOp is already in s->ops_in_flight when
mirror_co_read() waits for free slots, so if not enough slots are
immediately available, an operation can end up waiting for itself, or
two or more operations can wait for each other to complete, which
results in a hang.
Fix this by adding a flag to MirrorOp that tells us if the request is
already in flight (and therefore occupies slots that it will later
free), and picking only such operations for waiting.

-display none -vga none -serial mon:stdio \
-machine malta -kernel ./vmlinux-4.7.0-rc1.I6400 \
-cpu I6400 -smp 8 -vga std \
-append "printk.time=0 clocksource=GIC console=tty0 console=ttyS0 panic=-1" \
--no-reboot
Reports about a 9% failure rate:
Results summary:

-6: 9 times (9.00%), avg time 3.394 (0.02 varience/0.13 deviation)
Ran command 100 times, 91 passes
When re-run with "--accel tcg,thread=single" the instability goes
away.
Results summary:
0: 100 times (100.00%), avg time 17.318 (249.76 varience/15.80 deviation)

Which seems to indicate there is some aspect of the MIPS MTTCG fixes
that has been missed. Ideally we would fix that but I'm afraid I don't
have time to investigate and am not super familiar with the
architecture anyway. In lieu of someone tracking down the failure lets
disable it for now.

iotests: Add poke_file_[bl]e functions
Similarly to peek_file_[bl]e, we may want to write binary integers into

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.

qcow2: Avoid feature name extension on small cluster size
As the feature name table can be quite large (over 9k if all 64 bits
of all three feature fields have names; a mere 8 features leaves only
8 bytes for a backing file name in a 512-byte cluster), it is unwise
to emit this optional header in images with small cluster sizes.
Update iotest 036 to skip running on small cluster sizes; meanwhile,
note that iotest 061 never passed on alternative cluster sizes
(however, I limited this patch to tests with output affected by adding
feature names, rather than auditing for other tests that are not

block: trickle down the fallback image creation function use to the block drivers
Instead of checking the .bdrv_co_create_opts to see if we need the
fallback, just implement the .bdrv_co_create_opts in the drivers that
need it.
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.

Note that technically this driver reverts the image creation fallback
for the vxhs driver since I don't have a means to test it, and IMHO it
is better to leave it not supported as it was prior to generic image
creation patches.
Also drop iscsi_create_opts which was left accidentally.

Caused by
900c0ba373 commit which switches main RAM allocation to

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

*** 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

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.

in device code, so we need to hold the QEMU iothread lock while
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.
