[libvirt] [libvirt-java] [PATCH 0/2] Fixes for Device.listCapabilities
by Claudio Bley 09 Jan '14

09 Jan '14

Let the Device.listCapabilities method return an array filled with non-null string objects. Furthermore, the decoding of the character data does no longer depend upon the default JVM charset. This also fixes a memleak because the allocated memory was not freed in the old code. Patch #2 just adds a unit test which simply uses this function.

Re: [libvirt] [PATCH] libxl: Fix devid init in libxlMakeNicList

Yeah, I had numerous inquires and bugs come my way even after fixing vfb and vkb devid initialization in libxl with xen.git commit 5420f265. It took some time for the fix to make its way to downstream users. Since there is not yet a fix in Xen, it only makes sense to do the nic devid initialization in libvirt to fix PXE booting HVM domains. > The change here should accept any auto-assignment that makes it into > libxl_device_nic_init.

Otherwise, if intel_iommu=off, the ioctl returns 0, the function returns true, and we attempt to start a domain that is destined to fail. I've been doing a fair bit of testing of this series and with the exception of the above issue, haven't noticed any problems thus far. Unfortunately, you will need to rebase the series and post a v9, but I'm confident we can get this pushed after the 1.2.1 freeze. Thanks!

[libvirt] [PATCHv2] test driver: Add authentication to test driver.
by Richard W.M. Jones 08 Jan '14

08 Jan '14

There is no easy way to test authentication against libvirt. This commit modifies the test driver to allow simple username/password authentication. You modify the test XML by adding: <node> ... <auth> <user password="123456">rich</user> <user>jane</user> </auth> </node> If there are any /node/auth/user elements, then authentication is required by the test driver (if none are present, then the test driver will work as before and not require authentication). In the example above, two phony users are added: rich password: 123456 jane no password required The test driver will demand a username. If the password attribute is present (or if the username entered is wrong), then the password is also asked for and checked: $ virsh -c test://$(pwd)/testnode.xml list Enter username for localhost: rich Enter rich's password for localhost: *** Id Name State ---------------------------------------------------- 1 fv0 running 2 fc4 running Signed-off-by: Richard W.M.

[libvirt] [PATCH] event: clean up client side RPC code
by Eric Blake 08 Jan '14

08 Jan '14

Commit cfd62c1 was incomplete; I found more cases where error messages were being overwritten, and where the code between the three registration/deregistration APIs was not consistent. Since it is fairly easy to trigger an attempt to register an unregistered object, I also changed the error message from VIR_ERR_INTERNAL_ERROR to VIR_ERR_INVALID_ARG. * src/conf/object_event.c (virObjectEventCallbackListEventID): Inline... (virObjectEventStateEventID): ...into lone caller, and report error on failure. (virObjectEventCallbackListAddID, virObjectEventStateCallbackID) (virObjectEventCallbackListRemoveID) (virObjectEventCallbackListMarkDeleteID): Tweak error category. * src/remote/remote_driver.c (remoteConnectDomainEventRegister): Don't leak registration on failure. (remoteConnectDomainEventDeregisterAny) (remoteConnectNetworkEventDeregisterAny): Don't overwrite error.

[libvirt] [libvirt-java] [PATCH 0/3] Make the Java wrapper more fun to use
by Claudio Bley 08 Jan '14

08 Jan '14

This patchset first implements the ByteChannel interface for the Stream class which makes it readily usable with any standard Java library. Note, that this changes the wrapping of the virStreamRecv and virStreamSend function of the jna.Libvirt interface (which also makes this more efficient because a ByteBuffer is used instead of an Array). However, this interface should not be considered part of the public interface of the library, as with all classes part of the org.libvirt.jna package. In order to put this new functionality to use, the virDomainScreenshot function is wrapped and a unit test added to exercise it a bit.

by Pavel Fux 08 Jan '14

08 Jan '14

I have fixed all comments except: "We prefer passing the driver as an argument instead". I thought of it at first but I looked at the function call graph and it's not that easy. and you did the same in src/qemu/qemu_process.c:115

[libvirt] [libvirt-java] [PATCH] Use virFree in order to release memory acquired from libvirt
by Claudio Bley 08 Jan '14

08 Jan '14

When JNA is linked to a different runtime library than libvirt, using JNA's Native.free will probably lead to crashes as witnessed on Windows: # A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000077363290, pid=10180, tid=9908 # # JRE version: 7.0_25-b16 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.25-b01 mixed mode windows-amd64 compressed oops) # Problematic frame: # C [ntdll.dll+0x53290] RtlFreeHeap+0xd0 The root cause is that the libvirt DLL uses MSVCRT as its runtime library, whereas the jnidispatch DLL of JNA uses a different one. At runtime, when calling org.sun.com.jna.Native.free() the OS function RtlFreeHeap is called with an invalid Pointer that was actually allocated by MSVCRT's malloc. Basically, we cannot simply mix and match memory allocation functions from different runtime libraries, but have to call virFree for pointers orignating from libvirt itself. So, this patch re-adds and uses the virFree method which had been removed in commit 3220de292990bed71828fba2f3700bc846d440f2.

[libvirt] [libvirt-java] [PATCH] Fix wrapping of virStreamSend
by Claudio Bley 08 Jan '14

08 Jan '14

The native virStreamSend function is meant to be used to transfer byte data. Wrapping the function to use a Java String as the data depends on the default charset of the JVM and might impose further problems transferring \0 characters. Use a byte Array as the parameter type instead, as for virStreamRecv. Add the Stream.receive(byte[]) method which should be used instead of the legacy Stream.receive(String) method. The old method is kept for backward compatibility, but marked as deprecated. --- src/main/java/org/libvirt/Stream.java | 27 +++++++++++++++++++++++++-- src/main/java/org/libvirt/jna/Libvirt.java | 2 +- 2 files changed, 26 insertions(+), 3 deletions(-) diff --git a/src/main/java/org/libvirt/Stream.java b/src/main/java/org/libvirt/Stream.java index bd8e87f..404c9a0 100644 --- a/src/main/java/org/libvirt/Stream.java +++ b/src/main/java/org/libvirt/Stream.java @@ -142,6 +142,27 @@ public class Stream { } /** + * Write the data of the given string to a stream. + * + * @param data + * the string data to write + * @return the number of bytes written, -1 on error, -2 if the buffer is + * full + * @throws LibvirtException + * + * @deprecated This libvirt API was previously wrapped incorrectly, since + * the native function is meant to transfer bytes, not string + * data. + * Its effect depends on the default Charset on your platform + * which is determined on JVM startup. + * Use the {@link #send(byte[])} method instead. + */ + @Deprecated + public int send(String data) throws LibvirtException { + return send(data.getBytes(java.nio.charset.Charset.defaultCharset())); + } + + /** * Write a series of bytes to the stream. * * @param data @@ -149,9 +170,11 @@ public class Stream { * @return the number of bytes written, -1 on error, -2 if the buffer is * full * @throws LibvirtException + * + * @since 1.5.2 */ - public int send(String data) throws LibvirtException { - int returnValue = libvirt.virStreamSend(VSP, data, new NativeLong(data.length())); + public int send(byte[] data) throws LibvirtException { + int returnValue = libvirt.virStreamSend(VSP, data, new NativeLong(data.length)); processError(); return returnValue; } diff --git a/src/main/java/org/libvirt/jna/Libvirt.java b/src/main/java/org/libvirt/jna/Libvirt.java index 813f09b..98f2125 100644 --- a/src/main/java/org/libvirt/jna/Libvirt.java +++ b/src/main/java/org/libvirt/jna/Libvirt.java @@ -368,7 +368,7 @@ public interface Libvirt extends Library { int virStreamFinish(StreamPointer virStreamPtr) ; int virStreamFree(StreamPointer virStreamPtr) ; StreamPointer virStreamNew(ConnectionPointer virConnectPtr, int flags) ; - int virStreamSend(StreamPointer virStreamPtr, String data, NativeLong size); + int virStreamSend(StreamPointer virStreamPtr, byte[] data, NativeLong size); int virStreamSendAll(StreamPointer virStreamPtr, Libvirt.VirStreamSourceFunc handler, Pointer opaque); int virStreamRecv(StreamPointer virStreamPtr, byte[] data, NativeLong length); int virStreamRecvAll(StreamPointer virStreamPtr, Libvirt.VirStreamSinkFunc handler, Pointer opaque); -- 1.8.5.2.msysgit.0

[libvirt] [PATCH] libxl: Fix devid init in libxlMakeNicList
by Stefan Bader 08 Jan '14

08 Jan '14

This basically reverts commit ba64b97134a6129a48684f22f31be92c3b6eef96 "libxl: Allow libxl to set NIC devid". However assigning devid's before calling libxlMakeNic does not work as that is calling libxl_device_nic_init which sets it back to -1. Right now auto-assignment only works in the hotplug case. But even if that would be fixed at some point (if that is possible at all), this would add a weird dependency between Xen and libvirt versions. The change here should accept any auto-assignment that makes it into libxl_device_nic_init. My understanding is that a caller always is allowed to make the devid choice itself. And assuming libxlMakeNicList is only used on domain creation, a sequential numbering should be ok.

[libvirt] [PATCH 1/1] virsh nodecpustats erroneously returns stats for offline cpus on Linux

From: "Pradipta Kr. Banerjee" <bpradip(a)in.ibm.com> virsh nodecpustats erroneously returns stats for offline cpus on Linux To retrieve node cpu statistics on Linux system, the linuxNodeGetCPUstats function performs a minimal match of the input cpuid with the cpuid read from /proc/cpustat.
