In the case where mo_pushpop() is MO_32 and mo_stacksize() is MO_16 then the final writeback to EBP is done using MO_16 which can leave junk in the top 16-bits of EBP after executing ENTER. Change the writeback of EBP to use the same size indicated by mo_pushpop() to ensure that the full value is written back.

"if (n->host_hdr_len != n->guest_hdr_len)" is triggered, if body creates zero length/zero segment packet as there is nothing after guest header. qemu_sendv_packet_async() tries to send it. slirp discards it because it is smaller than Ethernet header, but returns 0 because tx hooks are supposed to return total length of data. 0 is propagated upwards and is interpreted as "packet has been sent" which is terrible because queue is being destroyed, nobody is waiting for TX to complete and assert it triggered. Fix is discard such empty packets instead of sending them. Length 1 packets will go via different codepath: virtqueue_push(q->tx_vq, elem, 0); virtio_notify(vdev, q->tx_vq); g_free(elem); and aren't problematic.

Bug RHEL-34618 was reported and Kevin Wolf identified the root cause. I missed that aio_co_reschedule_self() -> qemu_get_current_aio_context() only knows about qemu_aio_context/IOThread AioContexts and not about iohandler_ctx. It does not function correctly when going back from the iohandler_ctx to qemu_aio_context. Go back to open coding the AioContext transitions to avoid this bug. This reverts commit 1f25c172f83704e350c0829438d832384084a74d.

When using this fdset feature, we should not truncate the migration file because being given an fd means that the management layer is in control of the file and will likely already have some data written to it. This is further indicated by the presence of the 'offset' argument, which indicates the start of the region where QEMU is allowed to write. Fix the issue by replacing the O_TRUNC flag on open by an ftruncate call, which will take the offset into consideration. Fixes: 385f510df5 ("migration: file URI offset") Suggested-by: Daniel P.

When creating a CPU topology of 1 core per package, host-cache-info only uses the Host's addressable core IDs field (CPUID.04H.EAX[bits 31-26]), resulting in a conflict (on the multicore Host) between the Guest core topology information in this field and the Guest's actual cores number. Fix it by removing the unnecessary condition to cover 1 core per package case. This is safe because cores_per_pkg will not be 0 and will be at least 1.

Berrangé This effectively reverts commit 54c4ea8f3ae614054079395842128a856a73dbf9 Author: Zhao Liu Date: Sat Mar 9 00:01:37 2024 +0800 hw/core/machine-smp: Deprecate unsupported "parameter=1" SMP configurations but is not done as a 'git revert' since the part of the changes to the file hw/core/machine-smp.c which add 'has_XXX' checks remain desirable. Furthermore, we have to tweak the subsequently added unit test to account for differing warning message. The rationale for the original deprecation was: "Currently, it was allowed for users to specify the unsupported topology parameter as "1". For example, x86 PC machine doesn't support drawer/book/cluster topology levels, but user could specify "-smp drawers=1,books=1,clusters=1". This is meaningless and confusing, so that the support for this kind of configurations is marked deprecated since 9.0." There are varying POVs on the topic of 'unsupported' topology levels. It is common to say that on a system without hyperthreading, that there is always 1 thread. Likewise when new CPUs introduced a concept of multiple "dies', it was reasonable to say that all historical CPUs before that implicitly had 1 'die'. Likewise for the more recently introduced 'modules' and 'clusters' parameter'. From this POV, it is valid to set 'parameter=1' on the -smp command line for any machine, only a value > 1 is strictly an error condition. It doesn't cause any functional difficulty for QEMU, because internally the QEMU code is itself assuming that all "unsupported" parameters implicitly have a value of '1'. At the libvirt level, we've allowed applications to set 'parameter=1' when configuring a guest, and pass that through to QEMU. Deprecating this creates extra difficulty for because there's no info exposed from QEMU about which machine types "support" which parameters. Thus, libvirt can't know whether it is valid to pass 'parameter=1' for a given machine type, or whether it will trigger deprecation messages. Since there's no apparent functional benefit to deleting this deprecated behaviour from QEMU, and it creates problems for consumers of QEMU, remove this deprecation. Signed-off-by: Daniel P.

To make sure that calling 'qemu-img info' can't already have undesired side effects with a malicious image, just don't open the data file at all with BDRV_O_NO_IO. If nothing ever tries to do I/O, we don't need to have it open. This changes the output of iotests case 061, which used 'qemu-img info' to show that opening an image with an invalid data file fails. After this patch, it succeeds. Replace this part of the test with a qemu-io call, but keep the final 'qemu-img info' to show that the invalid data file is correctly displayed in the output.

This behaviour is intended for filenames that come directly from the command line and for backing files, which may come from the image file itself. Higher level management tools generally take care to verify that untrusted images don't contain a bad (or any) backing file reference; 'qemu-img info' is a suitable tool for this. However, for other files that can be referenced in images, such as qcow2 data files or VMDK extents, the string from the image file is usually not verified by management tools - and 'qemu-img info' wouldn't be suitable because in contrast to backing files, it already opens these other referenced files. So here the string should be interpreted as a literal local filename. More complex configurations need to be specified explicitly on the command line or in QMP. This patch changes bdrv_open_inherit() so that it only parses filenames if a new parameter parse_filename is true. It is set for the top level in bdrv_open(), for the file child and for the backing file child. All other callers pass false and disable filename parsing this way.
