+Subject: block-backend: Retain permissions after migration
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Git-commit: 492a119610129f65217580790971fa038e5492d3
+
+After migration, the permissions the guest device wants to impose on its
+BlockBackend are stored in blk->perm and blk->shared_perm.  In
+blk_root_activate(), we take our permissions, but keep all shared
+permissions open by calling `blk_set_perm(blk->perm, BLK_PERM_ALL)`.
+
+Only afterwards (immediately or later, depending on the runstate) do we
+restrict the shared permissions by calling
+`blk_set_perm(blk->perm, blk->shared_perm)`.  Unfortunately, our first
+call with shared_perm=BLK_PERM_ALL has overwritten blk->shared_perm to
+be BLK_PERM_ALL, so this is a no-op and the set of shared permissions is
+not restricted.
+
+Fix this bug by saving the set of shared permissions before invoking
+blk_set_perm() with BLK_PERM_ALL and restoring it afterwards.
+
+Fixes: 5f7772c4d0cf32f4e779fcd5a69ae4dae24aeebf

+       completion")

+Subject: iotest 302: use img_info_log() helper
+
+Git-commit: c30175d6fbc73a86a8013da195471d1a3490178f
+
+Instead of qemu_img_log("info", ..) use generic helper img_info_log().
+
+img_info_log() has smarter logic. For example it use filter_img_info()
+to filter output, which in turns filter a compression type. So it will
+help us in future when we implement a possibility to use zstd
+compression by default (with help of some runtime config file or maybe
+build option). For now to test you should recompile qemu with a small
+addition into block/qcow2.c before
+"if (qcow2_opts->has_compression_type":
+
+    if (!qcow2_opts->has_compression_type && version >= 3) {
+        qcow2_opts->has_compression_type = true;
+        qcow2_opts->compression_type = QCOW2_COMPRESSION_TYPE_ZSTD;
+    }

+
+Git-commit: fc2c3996a59683685a663deb3af12183ad24e4a7
+
+This test assumes that mirror flushes the source when entering the READY
+state, and that the format level will pass that flush on to the protocol
+level (where we intercept it with blkdebug).
+
+However, apparently that does not happen when using a VMDK image with
+zeroed_grain=on, which actually is the default set by testenv.py.  Right
+now, Python tests ignore IMGOPTS, though, so this has no effect; but
+Vladimir has a series that will change this, so we need to fix this test
+before that series lands.
+
+We can fix it by writing data to the source before we start the mirror
+job; apparently that makes the (VMDK) format layer change its mind and
+pass on the pre-READY flush to the protocol level, so the test passes
+again.  (I presume, without any data written, mirror just does a 64M
+zero write on the target, which VMDK with zeroed_grain=on basically just
+ignores.)
+
+Without this, we do not get a flush, and so blkdebug only sees a single
+flush at the end of the job instead of two, and therefore does not
+inject an error, which makes the block job complete instead of raising
+an error.

+
+We want iotests pass with both the default zlib compression and with

+
+Actually the only test that is interested in real compression type in
+test output is 287 (test for qcow2 compression type), so implement

+
+compression_type can't be used if we want to create image with
+compat=0.10. So, skip these tests, not many of them.

+
+Git-commit: 8f9e54ccfd047cbef09fe10fa75d59333052fb78
+
+qemu_img_verbose() has a drawback of not going through generic
+qemu_img_pipe_and_status(). qemu_img_verbose() is not very popular, so
+update the only two users to qemu_img_log() and drop qemu_img_verbose()
+at all.

+
+Git-commit: 984d7a52d5ca33a79e09f2617fe43e368dce4068
+
+We are going to add filtering in _qcow2_dump_header and want all tests
+use it.
+
+The patch is generated by commands:
+  cd tests/qemu-iotests
+  sed -ie 's/$PYTHON qcow2.py "$TEST_IMG" dump-header\($\| \)/_qcow2_dump_header\1/' ??? tests/*
+
+(the difficulty is to avoid converting dump-header-exts)

+Subject: iotests: specify some unsupported_imgopts for python iotests
+
+Git-commit: b30b8077243ea5dc93a540eedfecee3c74b19fa2
+
+We are going to support IMGOPTS for python iotests. Still some iotests
+will not work with common IMGOPTS used with bash iotests like
+specifying refcount_bits and compat qcow2 options. So we
+should define corresponding unsupported_imgopts for now.

+Subject: iotests.py: filter out successful output of qemu-img create
+
+Git-commit:  e877bba308c38033f73f444395b3cdcde48a3393
+
+The only "feature" of this "Formatting ..." line is that we have to
+update it every time we add new option. Let's drop it.

+
+We are going to support IMGOPTS environment variable like in bash
+tests. Corresponding global variable in iotests.py should be called
+imgopts. So to not interfere with function argument, rename it in
+advance.

+
+Git-commit: 7c15400cdd06b7b9b26c86eac1858fb9c0d77c1c
+
+We are going to support some addition IMGOPTS in python iotests like
+in bash iotests. Similarly to bash iotests, we want a way to skip some
+tests which can't work with specific IMGOPTS.
+
+Globally for python iotests we will not support things like
+'data_file=$TEST_IMG.ext_data_file' in IMGOPTS, so, forbid this
+globally in iotests.py.

+Subject: iotests.py: qemu_img*("create"): support
+ IMGOPTS='compression_type=zstd'
+
+Git-commit: 22e29bcea12ccf0e127b91917d959c69bebbd952
+
+Adding support of IMGOPTS (like in bash tests) allows user to pass a
+lot of different options. Still, some may require additional logic.
+
+Now we want compression_type option, so add some smart logic around it:
+ignore compression_type=zstd in IMGOPTS, if test want qcow2 in
+compatibility mode. As well, ignore compression_type for non-qcow2
+formats.
+
+Note that we may instead add support only to qemu_img_create(), but
+that works bad:
+
+1. We'll have to update a lot of tests to use qemu_img_create instead
+   of qemu_img('create'). (still, we may want do it anyway, but no
+   reason to create a dependancy between task of supporting IMGOPTS and
+   updating a lot of tests)
+
+2. Some tests use qemu_img_pipe('create', ..) - even more work on
+   updating
+
+3. Even if we update all tests to go through qemu_img_create, we'll
+   need a way to avoid creating new tests using qemu_img*('create') -
+   add assertions.. That doesn't seem good.
+
+So, let's add support of IMGOPTS to most generic
+qemu_img_pipe_and_status().

+
+If image doesn't have any compressed cluster we can easily switch to
+zlib compression, which may allow to downgrade the image.
+
+That's mostly needed to support IMGOPTS='compression_type=zstd' in some

+Subject: tests/qemu-iotests: Fix 051 for binaries without 'lsi53c895a'
+
+Git-commit: 0c83471bd75d329f4945e27dc1aa3a6cc2fda3bf
+
+The lsi53c895a SCSI adaptor might not be enabled in each and every
+x86 QEMU binary, e.g. it's disabled in the RHEL/CentOS build.
+Thus let's add a check to the 051 test so that it does not fail if
+this device is not available.
