[libvirt] [PATCH] libvirt.spec.in: BuildRequires: python-devel
by Michal Privoznik 03 Dec '14

03 Dec '14

As of f48ab7d8 we are trying to use python-devel to check python's version (or at least gnulib is doing that). However, the specfile doesn't say anything about it and therefore bootstrapping may fail on a minimal installation on rawhide.

[libvirt] [PATCH 00/11] Replace virXXXFree calls with virObjectUnref
by John Ferlan 02 Dec '14

02 Dec '14

Based on some recent review comments and a bit of internal IRC, this set of patches will change all the existing virXXXFree calls found in daemon/* and src/* to be virObjectUnref instead and then add a rule to inhibit usage unless the string/call is found in docs/*, tests/*, examples/*, tools/*, cfg.mk, libvirt_public.syms, include/libvirt/libvirt-*.h, and src/libvirt-*.c Most of this was brute force to start with and adding the rule afterwards caught a few oddball places. The reason for not wanting to call a virXXXFree function is because it will reset the last error, potentially clearing something and resulting in a message "an error was encountered but the cause is unknown". There were some places in the code which saved the last error, called the free function, then restored the last error. Those have now been adjusted to avoid that processing. Anything that required checking for a non NULL pointer prior to calling the virXXXFree is now not necessary since the virObjectUnref will check for NULL before continuing; whereas, the virXXXFree functions didn't allow NULL. If usage of the virXXXFree function is found during syntax-check, a message such as the following will be displayed: include/libvirt/libvirt-storage.h:256:int virStoragePoolFree (virStoragePoolPtr pool); include/libvirt/libvirt-storage.h:336:int virStorageVolFree (virStorageVolPtr vol); maint.mk: avoid using virXXXFree, use virObjectUnref instead make: *** [sc_prohibit_virXXXFree] Error 1 John Ferlan (11): rpc: Replace virXXXFree with virObjectUnref Replace virDomainFree with virObjectUnref Replace virNetworkFree with virObjectUnref Replace virNodeDeviceFree with virObjectUnref Replace virStorageVolFree with virObjectUnref Replace virStoragePoolFree with virObjectUnref Replace virStreamFree with virObjectUnref Replace virSecretFree with virObjectUnref Replace virNWFilterFree with virObjectUnref Replace virInterfaceFree with virObjectUnref Replace virDomainSnapshotFree with virObjectUnref cfg.mk | 12 +++ daemon/remote.c | 168 ++++++++++++-------------------- daemon/stream.c | 2 +- src/conf/domain_event.c | 4 +- src/conf/network_conf.c | 6 +- src/conf/network_event.c | 2 +- src/conf/node_device_conf.c | 6 +- src/conf/storage_conf.c | 6 +- src/conf/virchrdev.c | 4 +- src/esx/esx_driver.c | 2 +- src/fdstream.c | 2 +- src/hyperv/hyperv_driver.c | 2 +- src/interface/interface_backend_netcf.c | 6 +- src/interface/interface_backend_udev.c | 2 +- src/libxl/libxl_conf.c | 7 +- src/locking/sanlock_helper.c | 3 +- src/lxc/lxc_driver.c | 8 +- src/lxc/lxc_process.c | 8 +- src/nwfilter/nwfilter_driver.c | 6 +- src/qemu/qemu_command.c | 8 +- src/qemu/qemu_driver.c | 4 +- src/qemu/qemu_hotplug.c | 8 +- src/remote/remote_driver.c | 76 +++++++-------- src/rpc/gendispatch.pl | 17 ++-- src/secret/secret_driver.c | 6 +- src/storage/storage_backend.c | 4 +- src/storage/storage_backend_fs.c | 4 +- src/storage/storage_backend_rbd.c | 3 +- src/storage/storage_driver.c | 20 +--- src/uml/uml_conf.c | 2 +- src/vbox/vbox_common.c | 6 +- src/xenconfig/xen_common.c | 2 +- src/xenconfig/xen_sxpr.c | 2 +- 33 files changed, 155 insertions(+), 263 deletions(-) -- 1.9.3

[libvirt] [PATCH] qemu: update disk chain in vm->newDef when block job compeleted
by weiwei li 02 Dec '14

02 Dec '14

A bug will be hitted with libvirt+qemu+kvm when doing follow steps: 1.initial status :vm = base+z(z is a snapshot) 2. call snapshotCreateXML( ): vm = base+z +z' 3. call blockRebase( ): vm = base+z''(z rebase to z') 4.(after rebasing work done) vm shutdown and then start an error occured like this: "unable to set user and group to '0:0' on ' /path/to/disk': No such file or directory A second start may sucess. The error message reported by virSecurityDACSetSecurityDiskLabel when the disk chain is misused(that is base+z +z', after rebase, but z' was deleted yet).virSecurityDACSetSecurityDiskLabel used an old disk chain after rebasing. In qemuProcessHandleBlockJob when rebase complete, the disk chain in vm->def is updated but vm->newDef is not(when vm->newDef is not null). In shutdown( actrully in qemuProcessStop ), if vm->newDef is not null , vm->def will be replaced by vm->newDef, which contains a wrong disk chain!!! Then the next start will failed with above message. To fix it, update disk chain in vm->newDef in qemuProcessHandleBlockJob.
