We could: (1) have the same order in the QAPI definition as the the BLK_PERM_* flags are in LSb-first order. However, then there is no guarantee that they actually match (e.g. when someone modifies the QAPI schema without thinking of the BLK_PERM_* definitions). We could add static assertions, but these would break what’s good about this solution, namely its simplicity. (2) define the BLK_PERM_* flags based on the BlockPermission values. But this way whenever someone were to modify the QAPI order (perfectly sensible in theory), the BLK_PERM_* values would change. Because these values are used for file locking, this might break file locking between different qemu versions. Therefore, go the slightly more cumbersome way: Add a function to translate from the QAPI constants to the BLK_PERM_* flags.

This patch adds this capability to blkdebug. (Note that you cannot make blkdebug release or share permissions that it needs to take or cannot share, because this might result in assertion failures in the block layer. But if the blkdebug node has no parents, it will not take any permissions and share everything by default, so you can then freely choose what permissions to take and share.)

Whatever options the test needs should simply be appended. Some tests do this (with IMGOPTS=$(_optstr_add "$IMGOPTS" "...")), but that is cumbersome. It’s simpler to just give _make_test_img an -o parameter with which tests can add options. Some tests actually must override the user-specified options, though, for example when creating an image in a different format than the test $IMGFMT. For such cases, --no-opts allows clearing the current option list.

Accomplish this by passing options to _make_test_img via -o instead of $IMGOPTS. For some tests, there is no functional change because they already only appended options to IMGOPTS. For these, this patch is just a simplification. For others, this is a change, so they now heed user-specified $IMGOPTS.

Furthermore, we should not print qcow2.py's list of incompatible features because it differs depending on whether there is an external data file or not.

So, look at bdrv_child_try_set_perm. We are interested in tighten_restrictions only on failure. But on failure this field is not reliable: we may fail in the middle of permission update, some nodes are not touched and we don't know should their permissions be tighten or not. So, we rely on the fact that if we loose restrictions on some node (or BdrvChild), we'll not tighten restriction in the whole subtree as part of this update (assertions 2 and 3 rely on this fact as well). And, if we rely on this fact anyway, we can just check it on top, and don't pass additional pointer through the whole recursive infrastructure. Note also, that further patches will fix real bugs in permission update system, so now is good time to simplify it, as a help for further refactorings.

One consequence of this is that if we for example create a quorum with a size of 10GB and we mirror it to a new image the operation will write 10GB of actual zeroes to the destination image wasting a lot of time and disk space. Since a quorum has an arbitrary number of children of potentially different formats there is no way to report all possible allocation status flags in a way that makes sense, so this implementation only reports when a given region is known to contain zeroes (BDRV_BLOCK_ZERO) or not (BDRV_BLOCK_DATA). If all children agree that a region contains zeroes then we can return BDRV_BLOCK_ZERO using the smallest size reported by the children (because all agree that a region of at least that size contains zeroes). If at least one child disagrees we have to return BDRV_BLOCK_DATA. In this case we use the largest of the sizes reported by the children that didn't return BDRV_BLOCK_ZERO (because we know that there won't be an agreement for at least that size).

This is probably what we actually want here (judging from the "...to accommodate pathnames with spaces" comment), but before 5.1, we would have to quote the ${} slice to get the same behavior. In any case, without quoting, the reference output of many iotests is different between bash 5.1 and pre-5.1, which is not very good. The output of 5.1 is what we want, so whatever we do to get pre-5.1 to the same result, it means we have to fix the reference output of basically all tests that invoke _send_qemu_cmd (except the ones that only use single spaces in the commands they invoke). Instead of quoting the ${} slice (cmd="${$@: 1:...}"), we can also just not use array slicing and replace the whole thing with a simple "cmd=$1; shift", which works because all callers quote the whole $cmd argument anyway.
