| backport/apparmor-Allow-umount-dev.patch | apparmor: Allow umount(/dev) Commit 379c0ce4bfed introduced a call to umount(/dev) performed inside the namespace that we run QEMU in. As a result of this, on machines using AppArmor, VM startup now fails with internal error: Process exited prior to exec: libvirt: QEMU Driver error: failed to umount devfs on /dev: Permission denied The corresponding denial is AVC apparmor="DENIED" operation="umount" profile="libvirtd" name="/dev/" pid=70036 comm="rpc-libvirtd" Extend the AppArmor configuration for virtqemud and libvirtd so that this operation is allowed.

| backport/qemu_interface-Fix-managed-no-case-when-creating-an-ether.patch | qemu_interface: Fix managed='no' case when creating an ethernet interface In a recent commit of v9.0.0-rc1~192 I've tried to forbid case where a TAP device already exists, but at the same time it's managed by Libvirt (<interface type='ethernet'> <target dev='tap0' managed='yes'/> </interface>). NB, if @managed attribute is missing then it's assumed to be managed by Libvirt. Anyway, I've mistakenly put setting of VIR_NETDEV_TAP_CREATE_ALLOW_EXISTING flag into managed='yes' branch instead of managed='no' branch in qemuInterfaceEthernetConnect(). Move the setting of the flag into the correct branch. (cherry picked from commit d6a8b9eef70887e01fa5fd292580e14ca5eab08c) |

Passing NULL results in a glib warning being triggered. Check whether the hash table is not NULL and unref it only then. (cherry picked from commit c3afde9211b550d3900edc5386ab121f5b39fd3e) |

| backport/qemu_namespace-Deal-with-nested-mounts-when-umount-ing-de.patch | qemu_namespace: Deal with nested mounts when umount()-ing /dev In one of recent commits (v9.0.0-rc1~106) I've made our QEMU namespace code umount the original /dev. One of the reasons was enhanced security, because previously we just mounted a tmpfs over the original /dev. Thus a malicious QEMU could just umount("/dev") and it would get to the original /dev with all nodes. Now, on some systems this introduced a regression: failed to umount devfs on /dev: Device or resource busy But how this could be? We've moved all file systems mounted under /dev to a temporary location. Or have we? As it turns out, not quite. If there are two file systems mounted on the same target, e.g. like this: mount -t tmpfs tmpfs /dev/shm/ && mount -t tmpfs tmpfs /dev/shm/ then only the top most (i.e. the last one) is moved. See qemuDomainUnshareNamespace() for more info. Now, we could enhance our code to deal with these "doubled" mount points. Or, since it is the top most file system that is accessible anyways (and this one is preserved), we can umount("/dev") in a recursive fashion.

| backport/qemuProcessRefreshDisks-Don-t-skip-filling-of-disk-inform.patch | qemuProcessRefreshDisks: Don't skip filling of disk information if tray state didn't change Commit 5ef2582646eb98 added emitting of even when refreshign disk state, where it wanted to avoid sending the event if disk state didn't change. This was achieved by using 'continue' in the loop filling the information. Unfortunately this skips extraction of whether the device has a tray which is propagated into internal structures, which in turn broke cdrom media change as the code thought there's no tray for the device.

| backport/qemu_extdevice-Do-cleanup-host-only-for-VIR_DOMAIN_TPM_TY.patch | qemu_extdevice: Do cleanup host only for VIR_DOMAIN_TPM_TYPE_EMULATOR We only set up host for VIR_DOMAIN_TPM_TYPE_EMULATOR and thus similarly, we should do cleanup for the same type. This also fixes a crasher, in which qemuTPMEmulatorCleanupHost() accesses tpm->data.emulator.storagepath which is NULL for VIR_DOMAIN_TPM_TYPE_EXTERNAL.

| backport/qemu-blockjob-Handle-pending-blockjob-state-only-when-we-.patch | qemu: blockjob: Handle 'pending' blockjob state only when we need it The 'pending' state needs to be handled by the blockjob code only when the snapshot code requests a block-commit without auto-finalization. If we always handle it we fail to properly remove the blockjob data for the 'blockdev-create' job as that also transitions trhough 'pending' but we'd never update it once it reaches 'concluded' as the code already thinks that the job has finished and is no longer watching it. Introduce a 'processPending' property into block job data and set it only when we know that we need to process 'pending'. (cherry picked from commit c433c2434c0459df98ed3355ef615e341acd9009) |

| backport/virsh-Make-domif-setlink-work-more-than-once.patch | virsh: Make domif-setlink work more than once In virsh, we have this convenient domif-setlink command, which is just a wrapper over virDomainUpdateDeviceFlags() and which allows setting link state of given guest NIC. It does so by fetching corresponding <interface/> XML snippet and either putting <link state=''/> into it, OR if the element already exists setting the attribute to desired value. The XML is then fed into the update API. There's, however, a small bug in detecting the pre-existence of the element and its attribute. The code looks at "link" attribute, while in fact, the attribute is called "state". (cherry-picked from commit 6f3f6c0f763b9ffd8ef93eb124c88dd0b79138fc) |

| backport/storage-Fix-returning-of-locked-objects-from-virStoragePo.patch | storage: Fix returning of locked objects from 'virStoragePoolObjListSearch' CVE-2023-3750 'virStoragePoolObjListSearch' explicitly documents that it's returning a pointer to a locked and ref'd pool that maches the lookup function. This was not the case as in commit 0c4b391e2a9 (released in libvirt-8.3.0) the code was accidentally converted to use 'VIR_LOCK_GUARD' which auto-unlocked it when leaving the scope, even when the code was originally "leaking" the lock. Revert the corresponding conversion and add a comment that this function is intentionally leaking a locked object. (cherry picked from commit 9a47442366fcf8a7b6d7422016d7bbb6764a1098) |

| backport/remote-check-for-negative-array-lengths-before-allocation.patch | remote: check for negative array lengths before allocation While the C API entry points will validate non-negative lengths for various parameters, the RPC server de-serialization code will need to allocate memory for arrays before entering the C API. These allocations will thus happen before the non-negative length check is performed. Passing a negative length to the g_new0 function will usually result in a crash due to the negative length being treated as a huge positive number. This was found and diagnosed by ALT Linux Team with AFLplusplus. CVE-2024-2494 (cherry picked from commit 8a3f8d957507c1f8223fdcf25a3ff885b15557f2) |

| backport/qemu-domain-Fix-logic-when-tainting-domain.patch | qemu: domain: Fix logic when tainting domain Originally the code was skipping all repeated taints with the same taint flag but a logic bug introduced in commit 30626ed15b239c424ae inverted the condition.

This was noticed when going through oVirt logs as they use custom guest agent commands and the logs are totally spammed with this message.
