[Qemu-devel] [PULL 01/21] commit: Add NULL check for overlay_bs

[Kevin Wolf]

I can't see how overlay_bs could become NULL with the current code, but
other code in this function already checks it and we can make Coverity
happy with this check, so let's add it.

[Qemu-devel] [PULL 02/21] block: add clock_type field to ThrottleGroup

[Kevin Wolf]

From: Manos Pitsidianakis <el13635@mail.ntua.gr>

Clock type in throttling is currently inferred by the ThrottleTimer's
clock type even though it is a per-ThrottleGroup property; it doesn't
make sense to have different clock types in the same group. Moving this
to a field in ThrottleGroup can simplify some of the throttle functions.

[Qemu-devel] [PULL 03/21] block: remove timer canceling in throttle_config()

[Kevin Wolf]

From: Manos Pitsidianakis <el13635@mail.ntua.gr>

throttle_config() cancels the timers of the calling BlockBackend. This
doesn't make sense because other BlockBackends in the group remain
untouched. There's no need to cancel the timers in the one specific
BlockBackend so let's not do that. Throttled requests will run as
scheduled and future requests will follow the new configuration. This
also allows a throttle group's configuration to be changed even when it
has no members.

[Qemu-devel] [PULL 04/21] block/vmdk: Report failures in vmdk_read_cid()

[Kevin Wolf]

From: Peter Maydell <peter.maydell@linaro.org>

The function vmdk_read_cid() can fail if the read on the underlying
block device fails, or if there's a format error in the VMDK file.
However its API doesn't provide a mechanism to report these errors,
and in some cases we were returning a CID of 0 and in some cases a
CID of 0xffffffff, either of which might potentially be valid values.

Change the function to return 0 on success or a negative errno, and
return the CID via a uint32_t* argument. Update the callsites to
handle and propagate the error appropriately.

This fixes in passing a Coverity-spotted issue (CID 1350038) where
we weren't checking the return value from sscanf().

[Qemu-devel] [PULL 05/21] block/vpc.c: Handle write failures in get_image_offset()

[Kevin Wolf]

From: Peter Maydell <peter.maydell@linaro.org>

Coverity (CID 1355236) points out that get_image_offset() doesn't check that
it actually succeeded in writing the updated block bitmap to the file.
Check the error return from bdrv_pwrite_sync() and propagate an error
response back up to the function which calls get_image_offset() for
a write so that it can return the error to its caller.

get_sector_offset() is only used for reads, but we move it to the
same API for consistency.

[Qemu-devel] [PULL 07/21] block/qapi: Add qdev device name to query-block

[Kevin Wolf]

With -blockdev/-device, users can indirectly create anonymous
BlockBackends, while the state of such backends is still of interest. As
a preparation for making such BBs visible in query-block, make sure that
they can be identified even without a name by adding the ID/QOM path of
their qdev device to BlockInfo.

[Qemu-devel] [PULL 09/21] block/qapi: Use blk_all_next() for query-block

[Kevin Wolf]

This patch replaces the blk_next() loop in query-block by a
blk_all_next() one so that we also get access to BlockBackends that
aren't owned by the monitor. For now, the next thing we do is check
whether each BB has a name, so there is no semantic difference.

[Kevin Wolf]

Instead of listing only monitor-owned BlockBackends in query-block, also
add those anonymous BlockBackends that are owned by a qdev device and as
such under the control of the user.

This allows using query-block to inspect BlockBackends for the modern
configuration syntax with -blockdev and -device.

[Qemu-devel] [PULL 11/21] ide: bdrv_attach_dev() for empty CD-ROM

[Kevin Wolf]

If no drive=... option is passed (for an empty drive), we don't only
lack the BlockBackend normally created by parse_drive(), but we also
need to manually call blk_attach_dev().

IDE does not support hot unplug, but if it did, qdev would take care to
call the matching blk_detach_dev() on unplug.

This fixes at least the bug that such devices didn't show up in
query-block, and probably some more problems.

[Qemu-devel] [PULL 14/21] qemu-iotests: Test unplug of -device without drive

[Kevin Wolf]

This caused an assertion failure until recently because the BlockBackend
would be detached on unplug, but was in fact never attached in the first
place. Add a regression test.

[Qemu-devel] [PULL 19/21] block/vvfat: Fix compiler warning with gcc 7

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

gcc 7 complains that the sprintf() might write a null byte beyond the
end of the tail buffer.  That is wrong, but we can silence it by making
i unsigned (it can never be negative anyway, see the if condition right
before).  For some reason, this allows gcc to suddenly accurately
calculate the range of i so we can give the tail[] array the exact size
it needs to have (which is 8 bytes) without gcc complaining.

In addition, let us convert the sprintf() to snprintf(), because that is
always nicer, and add an assertion about the range of the return value
afterwards so we can see that "8 - len" will never be negative and thus
"entry->name + MIN(j, 8 - len)" will never be out of bounds.

[Qemu-devel] [PULL 20/21] blockdev: move BDRV_O_NO_BACKING option forward

[Kevin Wolf]

From: John Snow <jsnow@redhat.com>

For both external_snapshot_prepare and qmp_drive_mirror, we eventually
append the option BDRV_O_NO_BACKING. However, we generally do so after
we create the image.

To accommodate image creation wanting to verify that a backing file
exists or not, add this option prior to create to override checking
the existence of the backing file. This prevents QEMU from trying to
re-open a backing file that's already in use (thanks to qcow2 locking).

[Qemu-devel] [PULL 21/21] qemu-img: Check for backing image if specified during create

[Kevin Wolf]

From: John Snow <jsnow@redhat.com>

Or, rather, force the open of a backing image if one was specified
for creation. Using a similar -unsafe option as rebase, allow qemu-img
to ignore the backing file validation if possible.

It may not always be possible, as in the existing case when a filesize
for the new image was not specified.

This is accomplished by shifting around the conditionals in
bdrv_img_create, such that a backing file is always opened unless we
provide BDRV_O_NO_BACKING. qemu-img is adjusted to pass this new flag
when -u is provided to create.

Sorry for the heinous looking diffstat, but it's mostly whitespace.
