2021-04-30qapi/expr.py: Check type of union and alternate 'data' memberJohn Snow
Prior to this commit, specifying a non-object value here causes the QAPI parser to crash in expr.py with a stack trace with (likely) an AttributeError when we attempt to call that value's items() method. This member needs to be an object (Dict), and not anything else. Add a check for this with a nicer error message, and formalize that check with new test cases that exercise that error.

Now, bdrv_node_check_perm() is called only with fresh cumulative permissions, so its actually "refresh_perm". Move permission calculation to the function. Also, drop unreachable error message and rewrite the remaining one to be more generic (as now we don't know which node is added and which was already here).

2021-04-30block: adapt bdrv_append() for inserting filtersVladimir Sementsov-Ogievskiy
bdrv_append is not very good for inserting filters: it does extra permission update as part of bdrv_set_backing_hd(). During this update filter may conflict with other parents of top_bs. Instead, let's first do all graph modifications and after it update permissions. append-greedy-filter test-case in test-bdrv-graph-mod is now works, so move it out of debug option. Note: bdrv_append() is still only works for backing-child based filters. It's something to improve later. Note2: we use the fact that bdrv_append() is used to append new nodes, without backing child, so we don't need frozen check and inherits_from logic from bdrv_set_backing_hd().

2021-04-30block: add bdrv_attach_child_common() transaction actionVladimir Sementsov-Ogievskiy
Split out no-perm part of bdrv_root_attach_child() into separate transaction action. bdrv_root_attach_child() now moves to new permission update paradigm: first update graph relations then update permissions. qsd-jobs test output updated. Seems now permission update goes in another order. Still, the test comment say that we only want to check that command doesn't crash, and it's still so. Error message is a bit misleading as it looks like job was added first. But actually in new paradigm of graph update we can't distinguish such things. We should update the error message, but let's not do it now.

2021-04-30block: fix bdrv_replace_node_commonVladimir Sementsov-Ogievskiy
inore_children thing doesn't help to track all propagated permissions of children we want to ignore. The simplest way to correctly update permissions is update graph first and then do permission update. In this case we just referesh permissions for the whole subgraph (in topological-sort defined order) and everything is correctly calculated automatically without any ignore_children. So, refactor bdrv_replace_node_common to first do graph update and then refresh the permissions. Test test_parallel_exclusive_write() now pass, so move it out of debugging "if".

2021-04-30block: use topological sort for permission updateVladimir Sementsov-Ogievskiy
Rewrite bdrv_check_perm(), bdrv_abort_perm_update() and bdrv_set_perm() to update nodes in topological sort order instead of simple DFS. With topologically sorted nodes, we update a node only when all its parents already updated. With DFS it's not so. Consider the following example: A -+ | | | v | B | | v | C<-+ A is parent for B and C, B is parent for C. Obviously, to update permissions, we should go in order A B C, so, when we update C, all parent permissions already updated. But with current approach (simple recursion) we can update in sequence A C B C (C is updated twice). On first update of C, we consider old B permissions, so doing wrong thing. If it succeed, all is OK, on second C update we will finish with correct graph. But if the wrong thing failed, we break the whole process for no reason (it's possible that updated B permission will be less strict, but we will never check it). Also new approach gives a way to simultaneously and correctly update several nodes, we just need to run bdrv_topological_dfs() several times to add all nodes and their subtrees into one topologically sorted list (next patch will update bdrv_replace_node() in this manner). Test test_parallel_perm_update() is now passing, so move it out of debugging "if". We also need to support ignore_children in bdrv_parent_perms_conflict() For test 283 order of conflicting parents check is changed. Note also that in bdrv_check_perm() we don't check for parents conflict at root bs, as we may be in the middle of permission update in bdrv_reopen_multiple(). bdrv_reopen_multiple() will be updated soon.

Drop also comment in external_snapshot_prepare: - bdrv_append doesn't "remove" old bs in common sense, it sounds strange - the fact that bdrv_append can fail is obvious from the context - the fact that we must rollback all changes in transaction abort is known (it's the direct role of abort) Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Kevin Wolf <kwolf@redhat.com> Message-Id: <20210428151804.439460-5-vsementsov@virtuozzo.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2021-04-30tests/test-bdrv-graph-mod: add test_append_greedy_filterVladimir Sementsov-Ogievskiy
bdrv_append() is not quite good for inserting filters: it does extra permission update in intermediate state, where filter get it filtered child but is not yet replace it in a backing chain. Some filters (for example backup-top) may want permissions even when have no parents. And described intermediate state becomes invalid. That's (half a) reason, why we need "inactive" state for backup-top filter. bdrv_append() will be improved later, now let's add a unit test. Now test fails, so it runs only with -d flag. To run do ./test-bdrv-graph-mod -d -p /bdrv-graph-mod/append-greedy-filter from <build-directory>/tests.

2021-04-30tests/test-bdrv-graph-mod: add test_parallel_perm_updateVladimir Sementsov-Ogievskiy
Add test to show that simple DFS recursion order is not correct for permission update. Correct order is topological-sort order, which will be introduced later. Consider the block driver which has two filter children: one active with exclusive write access and one inactive with no specific permissions. And, these two children has a common base child, like this: ┌─────┐ ┌──────┐ │ fl2 │ ◀── │ top │ └─────┘ └──────┘ │ │ │ │ w │ ▼ │ ┌──────┐ │ │ fl1 │ │ └──────┘ │ │ │ │ w │ ▼ │ ┌──────┐ └───────▶ │ base │ └──────┘ So, exclusive write is propagated. Assume, we want to make fl2 active instead of fl1. So, we set some option for top driver and do permission update. If permission update (remember, it's DFS) goes first through top->fl1->base branch it will succeed: it firstly drop exclusive write permissions and than apply them for another BdrvChildren. But if permission update goes first through top->fl2->base branch it will fail, as when we try to update fl2->base child, old not yet updated fl1->base child will be in conflict. Now test fails, so it runs only with -d flag. To run do ./test-bdrv-graph-mod -d -p /bdrv-graph-mod/parallel-perm-update from <build-directory>/tests.

2021-04-30tests/test-bdrv-graph-mod: add test_parallel_exclusive_writeVladimir Sementsov-Ogievskiy
Add the test that shows that concept of ignore_children is incomplete. Actually, when we want to update something, ignoring permission of some existing BdrvChild, we should ignore also the propagated effect of this child to the other children. But that's not done. Better approach (update permissions on already updated graph) will be implemented later. Now the test fails, so it's added with -d argument to not break make check. Test fails with "Conflicts with use by fl1 as 'backing', which does not allow 'write' on base" because when updating permissions we can ignore original top->fl1 BdrvChild. But we don't ignore exclusive write permission in fl1->base BdrvChild, which is propagated. Correct thing to do is make graph change first and then do permission update from the top node. To run test do ./test-bdrv-graph-mod -d -p /bdrv-graph-mod/parallel-exclusive-write from <build-directory>/tests.

2021-04-06tests/tcg: add concept of container_hostsAlex Bennée
While docker is nominally multiarch these days it doesn't mean our distros actually package all cross compilers for all architectures. The upcoming Debian bullseye release will improve things further. At least for now we can get things like the 32 bit ARM compiler on it's 64 bit cousin.

You don't usually notice this is broken on developer system on x86 as we use the normal host compiler. However on other systems the -pc was extraneous. Also for 32 bit only i686 packages exist now so we should use those when available.

2021-04-04x86: rename oem-id and oem-table-id propertiesPaolo Bonzini
After introducing non-scalar machine properties, it would be preferrable to have a single acpitable property which includes both generic information (such as the OEM ids) and custom tables currently passed via -acpitable. Do not saddle ourselves with legacy oem-id and oem-table-id properties, instead mark them as experimental.

2021-03-30iotests/244: Test preallocation for data-file-rawMax Reitz
Three test cases: (1) Adding a qcow2 (metadata) file to an existing data file, see whether we can read the existing data through the qcow2 image. (2) Append data to the data file, grow the qcow2 image accordingly, see whether we can read the new data through the qcow2 image. (3) At runtime, add a backing image to a freshly created qcow2 image with an external data file (with data-file-raw). Reading data from the qcow2 image must return the same result as reading data from the data file, so everything in the backing image must be ignored. (This did not use to be the case, because without the L2 tables preallocated, all clusters would appear as unallocated, and so the qcow2 driver would fall through to the backing file.)

2021-03-30qcow2: Force preallocation with data-file-rawMax Reitz
Setting the qcow2 data-file-raw bit means that you can ignore the qcow2 metadata when reading from the external data file. It does not mean that you have to ignore it, though. Therefore, the data read must be the same regardless of whether you interpret the metadata or whether you ignore it, and thus the L1/L2 tables must all be present and give a 1:1 mapping. This patch changes 244's output: First, the qcow2 file is larger right after creation, because of metadata preallocation. Second, the qemu-img map output changes: Everything that was not explicitly discarded or zeroed is now a data area.

For its concurrent requests, 046 has always filtered the offset, probably because concurrent requests may settle in any order. However, it did not filter the request length, and so if requests with different lengths settle in an unexpected order (notably the longer request before the shorter request), the test fails (for no good reason).

15ce94a68ca ("block/qed: bdrv_qed_do_open: deal with errp") has improved the qed driver's error reporting, though sadly did not add a test for it. The good news are: There already is such a test, namely 116. The bad news are: Its reference output was not adjusted, and so now it fails. Let's fix the reference output, which has the nice side effect of demonstrating 15ce94a68ca's improvements.
