[libvirt] [question]qemu: migrate and destory vm immediately on destination causes libvirt deadlock or segment fault
by Wangrui (K) 06 May '14

06 May '14

Hi everyone, I do ram migration operation in KVM environment(libvirt1.2.4 qemu1.5.1). I encountered libvirtd deadlock or segmentfault when I destroy the migration VM on destination. I got the problem by flowing steps: step 1: migrate VM. step 2: execute "virsh destroy [VMName]" to destroy the migration VM on destination immediately. step 3: the destination libvirtd will be probably deadlock or segmentfault. Deadlock stack as followed: #0 0x00007fb5c18132d4 in __lll_lock_wait () from /lib64/libpthread.so.0 #1 0x00007fb5c180e659 in _L_lock_1008 () from /lib64/libpthread.so.0 #2 0x00007fb5c180e46e in pthread_mutex_lock () from /lib64/libpthread.so.0 #3 0x00007fb5c45d175f in virMutexLock (m=0x7fb5b0066ed0) at util/virthread.c:88 #4 0x00007fb5c45b6b04 in virObjectLock (anyobj=0x7fb5b0066ec0) at util/virobject.c:323 #5 0x00007fb5b8f4842a in qemuMonitorEmitEvent (mon=0x7fb5b0066ec0, event=0x7fb5b00688d0 "SHUTDOWN", seconds=1399374472, micros=509994, details=0x0) at qemu/qemu_monitor.c:1185 #6 0x00007fb5b8f62af2 in qemuMonitorJSONIOProcessEvent (mon=0x7fb5b0066ec0, obj=0x7fb5b0069080) at qemu/qemu_monitor_json.c:158 #7 0x00007fb5b8f62d25 in qemuMonitorJSONIOProcessLine (mon=0x7fb5b0066ec0, line=0x7fb5b005bbe0 "{\"timestamp\": {\"seconds\": 1399374472, \"microseconds\": 509994}, \"event\": \"SHUTDOWN\"}",msg=0x7fb5bd873c80) at qemu/qemu_monitor_json.c:195 #8 0x00007fb5b8f62f85 in qemuMonitorJSONIOProcess (mon=0x7fb5b0066ec0, data=0x7fb5b0060770 "{\"timestamp\": {\"seconds\": 1399374472, \"microseconds\": 509994},\"event\": \"SHUTDOWN\"}\r\n", len=85, msg=0x7fb5bd873c80) at qemu/qemu_monitor_json.c:237 #9 0x00007fb5b8f49aa0 in qemuMonitorIOProcess (mon=0x7fb5b0066ec0) at qemu/qemu_monitor.c:402 #10 0x00007fb5b8f4a09b in qemuMonitorIO (watch=20, fd=24, events=0, opaque=0x7fb5b0066ec0) at qemu/qemu_monitor.c:651 #11 0x00007fb5c458c4d9 in virEventPollDispatchHandles (nfds=17, fds=0x7fb5b0068a60) at util/vireventpoll.c:510 #12 0x00007fb5c458decf in virEventPollRunOnce () at util/vireventpoll.c:659 #13 0x00007fb5c458bfcc in virEventRunDefaultImpl () at util/virevent.c:308 #14 0x00007fb5c51a17a9 in virNetServerRun (srv=0x7fb5c5411d70) at rpc/virnetserver.c:1139 #15 0x00007fb5c5157f63 in main (argc=3, argv=0x7fff7fc04f48) at libvirtd.c:150 After analysis, I found it may be caused by multithreaded simultaneously access to the global variables "vm->privateData->mon". When problems occur，there are three libvirtd threads at work on destination host，suppose： ThreadA: migration thread，do qemuProcessStart. ThreadB: destroy thread，do qemuDoaminDestroy -> qemuProcessStop. ThreadC：Monitor Thread，do IOWrite、IORead and some other operations according to the mon->msg when mon->fd change. When threadB destroy happpens, this thread would handle the SUHTDOWN event. In threadA, when it sends QMP command to Qemu, it will operate the vm->privateData->mon lock. Such as the operation "qemuDomainObjEnterMonitor -> qemuMonitorSetBalloon -> qemuDomainObjExitMonitor", but it's not an atomic operation. If "virsh destroy [VMName]" happens during this operation, threadB will set the lock vm->privateData->mon to NULL in qemuProcessStop. And then in threadA, the function qemuDomainObjExitMonitor will fail to unlock vm->privateData->mon as it's NULL. So, threadC will never acquire the vm->privateData->mon lock and the deadlock problem happened. what was worse, if qemuMonitorSetBalloon perform succeed in threadA. ThreadA will coutinue to execute till it enter the function qemuMonitorSetDomainLog, it would cause segmentfault at VIR_FORCE_CLOSE(mon->logfd) due to mon is NULL. I could not find a good way to sovle this problem. Does anyone have good ideas? Thanks. Ps: I find an easy way to reproduce this problem more probably by following steps: step 1: Fault Injection, fit into this patch and update the libvirtd on destination host: --- src/qemu/qemu_process.c 2014-05-06 19:06:00.000000000 +0800 +++ src/qemu/qemu_process.c 2014-05-06 19:07:12.000000000 +0800 @@ -4131,6 +4131,8 @@ vm->def->mem.cur_balloon); goto cleanup; } + VIR_DEBUG("Fault Injection, sleep 3 seconds."); + sleep(3); qemuDomainObjEnterMonitor(driver, vm); if (vm->def->memballoon && vm->def->memballoon->period) qemuMonitorSetMemoryStatsPeriod(priv->mon, vm->def->memballoon->period); step 2: migrate VM. step 3: execute "virsh destroy [VMName]" to destroy the migration VM on destination when log prints "Fault Injection, sleep 3 seconds." step 4: the libvirtd deadlock stack occurs as above mentioned.

[libvirt] [libvirt PATCH] udev: consider the device a CDROM when ID_CDROM=1
by Giuseppe Scrivano 06 May '14

06 May '14

Some CDROM devices are reported by udev to have an ID_TYPE="generic" thus it is necessary to check if ID_CDROM is present. As a side effect, treating ID_TYPE="generic" as a missing ID_TYPE will enable checks for ID_DRIVE_FLASH_SD and ID_DRIVE_FLOPPY and the udevKludgeStorageType heuristic.

[libvirt] [PATCH] PCI: Introduce new device binding path using pci_dev.driver_override
by Alex Williamson 06 May '14

06 May '14

The driver_override field allows us to specify the driver for a device rather than relying on the driver to provide a positive match of the device. This shortcuts the existing process of looking up the vendor and device ID, adding them to the driver new_id, binding the device, then removing the ID, but it also provides a couple advantages. First, the above existing process allows the driver to bind to any device matching the new_id for the window where it's enabled. This is often not desired, such as the case of trying to bind a single device to a meta driver like pci-stub or vfio-pci. Using driver_override we can do this deterministically using: echo pci-stub > /sys/bus/pci/devices/0000:03:00.0/driver_override echo 0000:03:00.0 > /sys/bus/pci/devices/0000:03:00.0/driver/unbind echo 0000:03:00.0 > /sys/bus/pci/drivers_probe Previously we could not invoke drivers_probe after adding a device to new_id for a driver as we get non-deterministic behavior whether the driver we intend or the standard driver will claim the device. Now it becomes a deterministic process, only the driver matching driver_override will probe the device. To return the device to the standard driver, we simply clear the driver_override and reprobe the device: echo > /sys/bus/pci/devices/0000:03:00.0/preferred_driver echo 0000:03:00.0 > /sys/bus/pci/devices/0000:03:00.0/driver/unbind echo 0000:03:00.0 > /sys/bus/pci/drivers_probe Another advantage to this approach is that we can specify a driver override to force a specific binding or prevent any binding. For instance when an IOMMU group is exposed to userspace through VFIO we require that all devices within that group are owned by VFIO. However, devices can be hot-added into an IOMMU group, in which case we want to prevent the device from binding to any driver (preferred driver = "none") or perhaps have it automatically bind to vfio-pci. With driver_override it's a simple matter for this field to be set internally when the device is first discovered to prevent driver matches. Signed-off-by: Alex Williamson <alex.williamson(a)redhat.com> --- Changes since RFC: - Add ABI documentation (gregkh) - Documentation wording clarification (Christoffer) Nobody puked on the RFC and platform folks have posted a working version of this for platform devices, so I guess the only thing left to do is formally propose this as a new driver binding mechanism. I don't see much incentive to push this into the driver core since the match ultimately needs to be done by the bus driver. I think this is therefore like new_id/remove_id where PCI and USB implement separate, but consistent interfaces. I've pruned the CC list a bit from the RFC, but I've added libvirt folks since I expect they would be the first userspace tool that would adopt this.

[libvirt] LSN-2014-0003: Unsafe parsing of XML documents allows arbitrary file read
by Daniel P. Berrange 06 May '14

06 May '14

Libvirt Security Notice: LSN-2014-0003 ====================================== Summary: Unsafe parsing of XML documents allows arbitrary file read Reported on: 20140411 Published on: 20140506 Fixed on: 20140506 Reported by: Daniel P. Berrange <berrange(a)redhat.com> Richard Jones <rjones(a)redhat.com> Patched by: Daniel P. Berrange <berrange(a)redhat.com> See also: CVE-2014-0179 Description ----------- When parsing XML documents, libvirt passes the XML_PARSE_NOENT flag to libxml2 which instructs it to expand all entities in the XML document during parsing. This can be used to insert the contents of host OS files in the resulting parsed content. Although the flaw was introduced in 0.0.5, it was dormant having no ill effects, since the APIs involved all required the user to authenticate with privileges equivalent to root. In version 0.7.5 or later the virConnectCompareCPU / virConnectBaselineCPU methods activate the dormant bug, allowing for denial of service. In version 1.0.0 or later, if the admin opts in to using the new fine grained access control feature, there is potential for unprivileged information disclosure. Impact ------ A malicious user can pass libvirt an XML document which contains an entity that points to an arbitrary file on the host. When libvirt parses this document, it will insert the contents of that host file, which could allow the user to read the contents of files that they otherwise do not have permission to view. It also has the potential to cause a denial of service / indefinite hang of libvirt, if the entity points to a named pipe with no writer connected or certain proc files. If the libvirt installation is not using fine grained access control then virConnectCompareCPU and virConnectBaselineCPU APIs can be used by a read-only user to inflict a denial of service attack. If the libvirt installation is using fine grained access control, then as well as the denial of service attack, one or more of the following APIs can be used for information disclosure of files: virDomainDefineXML, virNetworkCreateXML, virNetworkDefineXML, virStoragePoolCreateXML, virStoragePoolDefineXML, virStorageVolCreateXML, virDomainCreateXML, virNodeDeviceCreateXML, virInterfaceDefineXML, virStorageVolCreateXMLFrom, virConnectDomainXMLFromNative, virConnectDomainXMLToNative, virSecretDefineXML, virNWFilterDefineXML, virDomainSnapshotCreateXML, virDomainSaveImageDefineXML, virDomainCreateXMLWithFiles, virConnectCompareCPU, virConnectBaselineCPU. Workaround ---------- Stop use of the fine grained access control mechanism, and restrict access to all the libvirt TCP/UNIX sockets to only trusted authenticated users. Simply denying access to the affected APIs in the access control policy is insufficient to mitigate the bug, since the XML document typically needs to be parsed before the access control check is applied in order to extra the UUID/name of the object to check. Access to the readonly libvirt socket must also be revoked Affected product ---------------- Name: libvirt Repository: git://libvirt.org/git/libvirt.git http://libvirt.org/git/?p=libvirt.git Branch:

[libvirt] [PATCH] util: changing all the "enum" structures into typedef's in "src/util/" directory.
by Julio Faracco 06 May '14

06 May '14

In "src/util/" there are many enumeration (enum) structures. Sometimes, it's better using a typedef for variable types, function types and other usages. Other enumeration will be changed to typedef's in the future.

[libvirt] [PATCH 1/5] conf: changing all the "enum" structures into typedef's in "src/conf/" directory.
by Julio Faracco 06 May '14

06 May '14

In "src/conf/" there are many enumeration (enum) structures like "src/util" directory. Sometimes, it's better using a typedef for variable types, function types and other usages. Other enumeration and folders will be changed to typedef's in the future. Most of the files changed in this commit included CPU (cpu_conf) enum structures.
