[PATCH] test_driver: support VIR_DOMAIN_AFFECT_LIVE in testUpdateDeviceFlags()

by John Levon

Pick up some more of the qemu_driver.c code so this function supports both CONFIG and LIVE updates. Note that qemuDomainUpdateDeviceFlags() passed vm->def to virDomainDeviceDefParse() for the VIR_DOMAIN_AFFECT_CONFIG case, which is technically incorrect; in the test driver code we'll fix this.

[PATCH] conf: Fix out-of-bounds write during cleanup of virDomainNumaDefNodeDistanceParseXML

by Rayhan Faizel

mem_nodes[i].ndistances is written outside the loop causing an out-of-bounds write leading to heap corruption. While we are at it, the entire cleanup portion can be removed as it can be handled in virDomainNumaFree. One instance of VIR_FREE is also removed and replaced with g_autofree. This patch also adds a testcase which would be picked up by ASAN, if this portion regresses.

[PATCH v2 0/8] ch: support restore with network devices

by Purna Pavan Chandra

Current ch driver supports restore only for domains without any network configuration defined. This was because libvirt explicitly passes network fds and CH did not had support to restore with new net FDS. This support has been added recently, https://github.com/cloud-hypervisor/cloud-hypervisor/pull/6402 The changes in this patch series includes moving to socket communication for restore api, create new net fds and pass them via SCM_RIGHTS to CH.

[PATCH v2] tests: Move domainEventState initialization to qemuTestDriverInit

by Rayhan Faizel

Under the test environment, driver->domainEventState is uninitialized. If a disk gets dropped, it will attempt to queue an event which will cause a segmentation fault. This crash does not occur during normal use. This patch moves driver->domainEventState initialization from qemuhotplugtest to qemuTestDriverInit in testutilsqemu (Credit goes to Michal Privoznik as he had already provided the diff). An additional test case is added to test dropping of disks with startupPolicy set as … [View More]optional.

[PATCH v1] security_manager: Ensure top lock is acquired before nested locks

by hongmianquan

We need to ensure top lock is acquired before nested lock. Otherwise deadlock issues may arise. We have the stack security driver, which internally manages other security drivers, we call them "top" and "nested". We call virSecurityStackPreFork() to lock the top one, and it also locks and then unlocks the nested drivers prior to fork. Then in qemuSecurityPostFork(), it unlocks the top one, but not the nested ones. Thus, if one of the nested drivers ("dac" or "selinux") is still locked, it will … [View More]cause a deadlock. We discovered this case: the nested list obtained through the qemuSecurityGetNested() will be locked for subsequent use, such as in virQEMUDriverCreateCapabilities(), where the nested list is locked using qemuSecurityGetDOI, but the top one is not locked beforehand. The problem stack is as follows: libvirtd thread1 libvirtd thread2 child libvirtd | | | | | | virsh capabilities qemuProcessLanuch | | | | | lock top | | | | lock nested | | | | | | fork------------------->|(held nested lock) | | | | | | unlock nested unlock top unlock top | | qemuSecuritySetSocketLabel | | lock nested (deadlock) In this commit, we ensure that the top lock is acquired before the nested lock, so during fork, it's not possible for another task to acquire the nested lock.

Re: [PATCH v1] security_manager: Ensure top lock is acquired before nested locks

by ByteDance

Yes, we have recently encountered this issue, and it is exactly the same as the scenario described in the bug report. We investigated the code and found this potential problem. The issue occurs when collecting information through the ‘virsh capabilities' while concurrently creating vm. The higher the frequency and concurrency, the more likely the issue will reproduce. We believe this is a very rare bug; our environment has been running for three years, and we've only encountered this issue once.… [View More]

[PATCH v2] conf: Fix rawio/sgio checks for non-scsi hostdev devices

by Rayhan Faizel

The current hostdev parsing logic sets rawio or sgio even if the hostdev type is not 'scsi'. The rawio field in virDomainHostdevSubsysSCSI overlaps with wwpn field in virDomainHostdevSubsysSCSIVHost, consequently setting a bogus pointer value such as 0x1 or 0x2 from virDomainHostdevSubsysSCSIVHost's point of view. This leads to a segmentation fault when it attempts to free wwpn. While setting sgio does not appear to crash, it shares the same flawed logic as setting rawio. Instead, we ensure … [View More]these are set only after the hostdev type check succeeds. This patch also adds two test cases to exercise both scenarios.
