The previous patches only cleaned up ATTRIBUTE_UNUSED flags cases; auditing the drivers found other places where flags was being used but not validated. In particular, domainGetXMLDesc had issues with clients accepting a different set of flags than the common virDomainDefFormat helper function.
* src/conf/domain_conf.c (virDomainDefFormat): Add common flag check. * src/storage/storage_driver.c (storageVolumeCreateXMLFrom): Pass 0 to drivers, since all flags are currently rejected. * src/uml/uml_driver.c (umlDomainAttachDeviceFlags) (umlDomainDetachDeviceFlags): Reject unknown flags. * src/vbox/vbox_tmpl.c (vboxDomainGetXMLDesc) (vboxDomainAttachDeviceFlags) (vboxDomainDetachDeviceFlags): Likewise. * src/qemu/qemu_driver.c (qemudDomainMemoryPeek): Likewise. (qemuDomainGetXMLDesc): Document common flag handling. * src/libxl/libxl_driver.c (libxlDomainGetXMLDesc): Likewise. * src/lxc/lxc_driver.c (lxcDomainGetXMLDesc): Likewise. * src/openvz/openvz_driver.c (openvzDomainGetXMLDesc): Likewise. * src/phyp/phyp_driver.c (phypDomainGetXMLDesc): Likewise. * src/test/test_driver.c (testDomainGetXMLDesc): Likewise. * src/vmware/vmware_driver.c (vmwareDomainGetXMLDesc): Likewise. * src/xenapi/xenapi_driver.c (xenapiDomainGetXMLDesc): Likewise. ---

I don't think that this is a good idea. Even if the function doesn't have any flags at the moment this change will give us trouble when someone want's to add a flag to virStorageVolCreateXMLFrom that should have been passed down to the backend's buildVolFrom function. ACK, to a patch without this hunk. -- Matthias Bolte http://photron.blogspot.com
