[Qemu-devel] [PULL 01/34] block: Constify data passed by pointer to blk_name

[Kevin Wolf]

From: Krzysztof Kozlowski <krzk@kernel.org>

blk_name() is not modifying data passed to it through pointer and it
returns also a pointer to const so the argument can be made const for
code safeness.

[Qemu-devel] [PULL 04/34] Revert "block/io: Comment out permission assertions"

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

This reverts commit e3e0003a8f6570aba1421ef99a0b383a43371a74.

This commit was necessary for the 2.9 release because we were unable to
fix the underlying issue(s) in time. However, we will be for 2.10.

[Qemu-devel] [PULL 05/34] qemu-img: simplify img_convert

[Kevin Wolf]

From: Peter Lieven <pl@kamp.de>

img_convert has been around before there was an ImgConvertState or
a block backend, but it has never been modified to directly use
these structs. Change this by parsing parameters directly into
the ImgConvertState and directly use BlockBackend where possible.
Furthermore variable initialization has been reworked and sorted.

[Qemu-devel] [PULL 06/34] migration: Call blk_resume_after_migration() for postcopy

[Kevin Wolf]

Commit d35ff5e6 ('block: Ignore guest dev permissions during incoming
migration') added blk_resume_after_migration() to the precopy migration
path, but neglected to add it to the duplicated code that is used for
postcopy migration. This means that the guest device doesn't request the
necessary permissions, which ultimately led to failing assertions.

Add the missing blk_resume_after_migration() to the postcopy path.

[Qemu-devel] [PULL 07/34] qemu-iotests: Filter HMP readline escape characters

[Kevin Wolf]

The only thing the escape characters achieve is making the reference
output unreadable and lines that are potentially so long that git
doesn't want to put them into an email any more. Let's filter them out.

[Qemu-devel] [PULL 09/34] block: An empty filename counts as no filename

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

Reproducer:
    $ ./qemu-img info ''
    qemu-img: ./block.c:1008: bdrv_open_driver: Assertion
        `!drv->bdrv_needs_filename || bs->filename[0]' failed.

This patch fixes this to be:

[Kevin Wolf]

We test for the presence of perl and bc and save their path in the
variables PERL_PROG and BC_PROG, but never actually make use of them.
Remove the checks and assignments so qemu-iotests can run even when
bc isn't installed.

From: Fam Zheng <famz@redhat.com>

Reported by Coverity. We already use bs in bdrv_inc_in_flight before
checking for NULL. It is unnecessary as all callers pass non-NULL bs, so
drop it.

[Qemu-devel] [PULL 14/34] iotests: Launch qemu-nbd with -e 42

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

There is no reason for the qemu-nbd server used for tests not to accept
an arbitrary number of clients. In fact, test 181 will require it to
accept two clients at the same time (and thus it fails before this
patch).

This patch updates common.rc to launch qemu-nbd with -e 42 which should
be enough for all of our current and future tests.

[Qemu-devel] [PULL 17/34] iotests: 109: Filter out "len" of failed jobs

[Kevin Wolf]

From: Fam Zheng <famz@redhat.com>

Mirror calculates job len from current I/O progress:

    s->common.len = s->common.offset +
                    (cnt + s->sectors_in_flight) * BDRV_SECTOR_SIZE;

The final "len" of a failed mirror job in iotests 109 depends on the
subtle timing of the completion of read and write issued in the first
mirror iteration.  The second iteration may or may not have run when the
I/O error happens, resulting in non-deterministic output of the
BLOCK_JOB_COMPLETED event text.

Similar to what was done in a752e4786, filter out the field to make the
test robust.

[Qemu-devel] [PULL 18/34] block: Do not unref bs->file on error in BD's open

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

The block layer takes care of removing the bs->file child if the block
driver's bdrv_open()/bdrv_file_open() implementation fails. The block
driver therefore does not need to do so, and indeed should not unless it
sets bs->file to NULL afterwards -- because if this is not done, the
bdrv_unref_child() in bdrv_open_inherit() will dereference the freed
memory block at bs->file afterwards, which is not good.

We can now decide whether to add a "bs->file = NULL;" after each of the
offending bdrv_unref_child() invocations, or just drop them altogether.
The latter is simpler, so let's do that.

[Qemu-devel] [PULL 19/34] block: fix alignment calculations in bdrv_co_do_zero_pwritev

[Kevin Wolf]

From: "Denis V. Lunev" <den@openvz.org>

tail_padding_bytes is calculated wrong. F.e. for
    offset = 0
    bytes = 2048
    align = 512
we will have tail_padding_bytes = 512 which is definitely wrong. The patch
fixes that arithmetics.

Fortunately this problem is harmless, we will have 1 extra allocation and
free thus there is no need to put this into stable. The problem is here
from the very beginning.

[Qemu-devel] [PULL 20/34] qemu-img/convert: Use @opts for one thing only

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

After storing the creation options for the new image into @opts, we
fetch some things for our own information, like the backing file name,
or whether to use encryption or preallocation.

With the -n parameter, there will not be any creation options; this is
not too bad because this just means that querying a NULL @opts will
always return the default value.

However, we also use @opts for the --object options. Therefore, @opts is
not necessarily NULL if -n was specified; instead, it may contain those
options. In practice, this probably does not cause any problems because
there most likely is no object that supports any of the parameters we
query here, but this is neither something we should rely on nor does
this variable reuse make the code very nice to read.

Therefore, just use a separate variable for the --object options.

[Qemu-devel] [PULL 21/34] qemu-img/convert: Move bs_n > 1 && -B check down

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

It does not make much sense to use a backing image for the target when
you concatenate multiple images (because then there is no correspondence
between the source images' backing files and the target's); but it was
still possible to give one by using -o backing_file=X instead of -B X.

Fix this by moving the check.

(Also, change the error message because -B is not the only way to
 specify the backing file, evidently.)

[Qemu-devel] [PULL 24/34] block: Add errp to b{lk,drv}_truncate()

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

For one thing, this allows us to drop the error message generation from
qemu-img.c and blockdev.c and instead have it unified in
bdrv_truncate().

[Qemu-devel] [PULL 25/34] block: Add errp to BD.bdrv_truncate()

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

Add an Error parameter to the block drivers' bdrv_truncate() interface.
If a block driver does not set this in case of an error, the generic
bdrv_truncate() implementation will do so.

Where it is obvious, this patch also makes some block drivers set this
value.

[Qemu-devel] [PULL 26/34] block: Add .bdrv_truncate() error messages

[Kevin Wolf]

From: Max Reitz <mreitz@redhat.com>

Add missing error messages for the block driver implementations of
.bdrv_truncate(); drop the generic one from block.c's bdrv_truncate().

Since one of these changes touches a mis-indented block in
block/file-posix.c, this patch fixes that coding style issue along the
way.

[Qemu-devel] [PULL 27/34] qcow2: Allow discard of final unaligned cluster

[Kevin Wolf]

From: Eric Blake <eblake@redhat.com>

As mentioned in commit 0c1bd46, we ignored requests to
discard the trailing cluster of an unaligned image.  While
discard is an advisory operation from the guest standpoint,
(and we are therefore free to ignore any request), our
qcow2 implementation exploits the fact that a discarded
cluster reads back as 0.  As long as we discard on cluster
boundaries, we are fine; but that means we could observe
non-zero data leaked at the tail of an unaligned image.

Enhance iotest 66 to cover this case, and fix the implementation
to honor a discard request on the final partial cluster.

[Qemu-devel] [PULL 29/34] block: assert no image modification under BDRV_O_INACTIVE

[Kevin Wolf]

From: "Denis V. Lunev" <den@openvz.org>

As long as BDRV_O_INACTIVE is set, the image file is only opened so we
have a file descriptor for it. We're definitely not supposed to modify
the image, it's still owned by the migration source.

This commit is an addition to 09e0c771 but the assert() is added to
bdrv_truncate().

[Qemu-devel] [PULL 31/34] qemu-img: use blk_co_pwrite_zeroes for zero sectors when compressed

[Kevin Wolf]

From: Lidong Chen <lidongchen@tencent.com>

When the buffer is zero, blk_co_pwrite_zeroes is more effective than
blk_co_pwritev with BDRV_REQ_WRITE_COMPRESSED. This patch can reduce
the time for converting qcow2 images with lots of zero data.

Quick question:

Is this mention of test 181 the same test that occurs earlier in the
pull request as 8/34?  If so, should the series have been reordered for
bisectability?  If not, should the commit message be touched up?

At any rate, bisectability of qemu-iotests is less of a concern than
bisectability of 'make check' success, so I don't think your answer
invalidates the pull request.

Doesn't this break bisectability?

Yes, it's the same test 181 and if someone had noticed before I sent the
pull request, I might have reordered the patches, but I don't think
there's any practical bisectability problem with introducing a
qemu-iotests case that fails on NBD. If you bisect, you typically bisect
for a specific setup and test case rather than running the full set of
qemu-iotests.

I'm merging this pull request.  Regarding the discussion about
bisectability on Patch 4:

< kwolf> stefanha: It will reintroduce an assertion failure that we "fixed" by uncommenting the assertion for the 2.9 release. Not sure about bisectability in this case; what already broke it is really
               the temporary workaround, not reverting it.
< kwolf> stefanha: Do you think we should keep the assertion disabled until the real fix is there? It means that we can't find other problematic cases in the meantime.
< stefanha> kwolf: Depends on how likely it is that other problematic cases exist
< stefanha> kwolf: If you want to go ahead I can merge the pull request.
< kwolf> stefanha: I think it's okay to go ahead, but if you're not sure about it, I can do a v2 without that patch. I just need to know that you expect me to send a v2.
< stefanha> kwolf: I will merge it, was just waiting for the discussion on Patch 4 to finish.

Thanks, applied to my staging tree:
