[libvirt] [PATCH] libxl: fix regression introduced by commit 4ab8cd77
by Jim Fehlig 16 Mar '15

16 Mar '15

Commit 4ab8cd77 added a check requiring input devices to have a bus type of VIR_DOMAIN_INPUT_BUS_USB, failing to start the domain otherwise. But virDomainDefParseXML adds implicit mouse and keyboard if a graphics device is configured. See calls to virDomainDefMaybeAddInput. The regression is fixed by removing the check requiring USB input devices, and skipping non-USB input devices when populating USB 'usbdevice' in libxl_domain_build_info struct.

[libvirt] [PATCH] daemon: avoid memleak when ListAll returns nothing
by Eric Blake 16 Mar '15

Commit 4f25146 (v1.2.8) managed to silence Coverity, but at the cost of a memory leak detected by valgrind: ==24129== 40 bytes in 5 blocks are definitely lost in loss record 355 of 637 ==24129== at 0x4A08B1C: realloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==24129== by 0x5084B8E: virReallocN (viralloc.c:245) ==24129== by 0x514D5AA: virDomainObjListExport (domain_conf.c:22200) ==24129== by 0x201227DB: qemuConnectListAllDomains (qemu_driver.c:18042) ==24129== by 0x51CC1B6: virConnectListAllDomains (libvirt-domain.c:6797) ==24129== by 0x14173D: remoteDispatchConnectListAllDomains (remote.c:1580) ==24129== by 0x121BE1: remoteDispatchConnectListAllDomainsHelper (remote_dispatch.h:1072) In short, every time a client calls a ListAll variant and asks for the resulting list, but there are 0 elements to return, we end up leaking the 1-entry array that holds the NULL terminator. What's worse, a read-only client can access these functions in a tight loop to cause libvirtd to eventually run out of memory; and this can be considered a denial of service attack against more privileged clients. Thankfully, the leak is so small (8 bytes per call) that you would already have some other denial of service with any guest calling the API that frequently, so an out-of-memory crash is unlikely enough that this did not warrant a CVE. * daemon/remote.c (remoteDispatchConnectListAllDomains) (remoteDispatchDomainListAllSnapshots) (remoteDispatchDomainSnapshotListAllChildren) (remoteDispatchConnectListAllStoragePools) (remoteDispatchStoragePoolListAllVolumes) (remoteDispatchConnectListAllNetworks) (remoteDispatchConnectListAllInterfaces) (remoteDispatchConnectListAllNodeDevices) (remoteDispatchConnectListAllNWFilters) (remoteDispatchConnectListAllSecrets) (remoteDispatchNetworkGetDHCPLeases): Plug leak.

[libvirt] [PATCH 00/12] More cleanup from IOThreads changes
by John Ferlan 16 Mar '15

16 Mar '15

During the review process a few things were pointed at as perhaps needing some adjustments based on what was done for IOThreads. Specifically a memory leak in PinVcpuFlags since PinIOThreads was just a copy of the Vcpu code and secondarily since the IOThreads code "reused" the virDomainVcpuPin* data structures and API's, those should change names to be more generic.

[libvirt] [PATCH] rpm-build: use pkg-config to detect wireshark presence
by Pavel Hrdina 16 Mar '15

16 Mar '15

Wireshark supports pkg-config since 1.11.3. Right now we build wireshark-dissectior tool as default trough rpm build only on fedora >= 21 and there is newer wireshark that supports pkg-config. If someone wants to build libvirt with wireshark-dissector against older wireshark, they should specify the location by hand. This patch is mainly to fix wrong dependency on wireshark binary as it doesn't make sense to require that binary file to just get version info of that package in makefile.

[libvirt] [libvirt-perl PATCHv2 0/2] Add virDomainGetIOThreads and virDomainPinIOThread bindings
by John Ferlan 16 Mar '15

16 Mar '15

v1: http://www.redhat.com/archives/libvir-list/2015-March/msg00352.html Since I essentially copied the vcpuinfo.pl example to create the iothreadsinfo.pl example, I figured I'd resend the patches again with the changes that ended up working which are slightly different than the review comment. The major difference being I needed to limit the unpack bits format. Instead of "b*", I found "b$nodeinfo->{cpus}" would print the just the cpu count bits. Made the same change to the vcpuinfo.pl example. I didn't modify the Virt.xs Safefree(info) check although it seems it would be possible if desired.
