[libvirt] [PATCH v2] qemuDomainChangeGraphics: Check listen address change by listen type
by Michal Privoznik 20 Jun '13

20 Jun '13

Currently, we have a bug when updating a graphics device. A graphics device can have a listen address set. This address is either defined by user (in which case it's type is VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_ADDRESS) or it can be inherited from a network (in which case it's type is VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_NETWORK). However, in both cases we have a listen address to process (e.g. during migration, as I've tried to fix in 7f15ebc7). Later, when a user tries to update the graphics device (e.g. set a password), we check if listen addresses match the original as qemu doesn't know how to change listen address yet. Hence, users are required to not change the listen address. The implementation then just dumps listen addresses and compare them. Previously, while dumping the listen addresses, NULL was returned for NETWORK. After my patch, this is no longer true, and we get a listen address for olddev even if it is a type of NETWORK. So we have a real string on one side, the NULL from user's XML on the other side and hence we think user wants to change the listen address and we refuse it. Therefore, we must take the type of listen address into account as well. --- src/qemu/qemu_hotplug.c | 70 +++++++++++++++++++++++++++++++------------------ 1 file changed, 44 insertions(+), 26 deletions(-) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index 6c07af5..637dbc5 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -1960,10 +1960,9 @@ qemuDomainChangeGraphics(virQEMUDriverPtr driver, virDomainGraphicsDefPtr dev) { virDomainGraphicsDefPtr olddev = qemuDomainFindGraphics(vm, dev); - const char *oldListenAddr, *newListenAddr; - const char *oldListenNetwork, *newListenNetwork; int ret = -1; virQEMUDriverConfigPtr cfg = virQEMUDriverGetConfig(driver); + size_t i; if (!olddev) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", @@ -1971,10 +1970,49 @@ qemuDomainChangeGraphics(virQEMUDriverPtr driver, goto cleanup; } - oldListenAddr = virDomainGraphicsListenGetAddress(olddev, 0); - newListenAddr = virDomainGraphicsListenGetAddress(dev, 0); - oldListenNetwork = virDomainGraphicsListenGetNetwork(olddev, 0); - newListenNetwork = virDomainGraphicsListenGetNetwork(dev, 0); + if (dev->nListens != olddev->nListens) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("cannot change the number of listen addresses")); + goto cleanup; + } + + for (i = 0; i < dev->nListens; i++) { + virDomainGraphicsListenDefPtr listen = &dev->listens[i]; + virDomainGraphicsListenDefPtr oldlisten = &olddev->listens[i]; + + if (listen->type != oldlisten->type) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("cannot change the type of listen address")); + goto cleanup; + } + + switch ((enum virDomainGraphicsListenType) listen->type) { + case VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_ADDRESS: + if (STRNEQ_NULLABLE(listen->address, oldlisten->address)) { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", + dev->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC ? + _("cannot change listen address setting on vnc graphics") : + _("cannot change listen address setting on spice graphics")); + goto cleanup; + } + break; + + case VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_NETWORK: + if (STRNEQ_NULLABLE(listen->network, oldlisten->network)) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + dev->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC ? + _("cannot change listen network setting on vnc graphics") : + _("cannot change listen network setting on spice graphics")); + goto cleanup; + } + break; + + case VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_NONE: + case VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_LAST: + /* nada */ + break; + } + } switch (dev->type) { case VIR_DOMAIN_GRAPHICS_TYPE_VNC: @@ -1985,16 +2023,6 @@ qemuDomainChangeGraphics(virQEMUDriverPtr driver, _("cannot change port settings on vnc graphics")); goto cleanup; } - if (STRNEQ_NULLABLE(oldListenAddr,newListenAddr)) { - virReportError(VIR_ERR_INTERNAL_ERROR, "%s", - _("cannot change listen address setting on vnc graphics")); - goto cleanup; - } - if (STRNEQ_NULLABLE(oldListenNetwork,newListenNetwork)) { - virReportError(VIR_ERR_INTERNAL_ERROR, "%s", - _("cannot change listen network setting on vnc graphics")); - goto cleanup; - } if (STRNEQ_NULLABLE(olddev->data.vnc.keymap, dev->data.vnc.keymap)) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("cannot change keymap setting on vnc graphics")); @@ -2040,16 +2068,6 @@ qemuDomainChangeGraphics(virQEMUDriverPtr driver, _("cannot change port settings on spice graphics")); goto cleanup; } - if (STRNEQ_NULLABLE(oldListenAddr, newListenAddr)) { - virReportError(VIR_ERR_INTERNAL_ERROR, "%s", - _("cannot change listen address setting on spice graphics")); - goto cleanup; - } - if (STRNEQ_NULLABLE(oldListenNetwork, newListenNetwork)) { - virReportError(VIR_ERR_INTERNAL_ERROR, "%s", - _("cannot change listen network setting on spice graphics")); - goto cleanup; - } if (STRNEQ_NULLABLE(olddev->data.spice.keymap, dev->data.spice.keymap)) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", -- 1.8.1.5

[libvirt] [PATCH] Add optional serial id for USB devices in hostdev
by david.waring＠rd.bbc.co.uk 20 Jun '13

From: David Waring <david.waring(a)rd.bbc.co.uk> This patch adds the ability to include a serial element in a hostdev/source to select a device with a particular serial number. Patch for bugzilla #914883. This allows specific USB devices to attached to guests when there may be more than one of the same USB device attached to a host. The serial number is optional so that without it existing behaviour is maintained.

[libvirt] [PATCH 00/19] Support for access control
by Daniel P. Berrange 20 Jun '13

20 Jun '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> This series (which depends on the Xen refactoring patches) adds support for access control checks on all APIs that run inside libvirtd. The first patch defines the basic objects which can be checked and the permissions associated with each object. In addition it provides the basic internal (pluggable) API for access control checks Later there are policykit and selinux drivers for the access control framework. Neither of these is currently optimal but they have basic functionality working To ensure that we don't forget access control checks when adding new APIs, we maintain metadata in the remote_protocol.x file against each method declaring what access control check must be done. There are actually two checks possible. The first check is against the object being used. The optional second check is against the objects being returned (if any). The latter is used to filter what can be seen when asking for a list of objects (eg 'virsh list' gets filtered) Again to ensure accurate checks, we automate the generation of methods for applying access control checks to each API. These helper methods are named to match the public API names. The last patch ensures that every method listed in the virXXXXDriverPtr tables has a call to an access control helper with the same name as the public API. And of course there are the patches which actually add the access control checks. Still todo - Not all Xen methods have access control checks yet. This causes the test case in the last patch to report failures - Have not wired up the checks for filtering the returned objects in any driver yet - The polkit driver is inefficient since it spawns pkcheck for each check. We need to talk to DBus directly since ACL checks will be very frequent and need to be lightweight - The SELinux driver is validating against the label of libvirtd. We need to validate against the label of the virDomainDefPtr security model or some equivalent for other objects. - Need to write a generic RBAC access control impl. It was hoped that new polkit would make this obsolete. Polkit is still unable to do access control checks for non-local users though eg it can't validate against SASL usernames or x509 certs.

[libvirt] [PATCH 00/11] storage_scsi: Stable SCSI host addressing support
by Osier Yang 20 Jun '13

20 Jun '13

The SCSI host number is not stable on Linux platform, the number can be changed after a system rebooting or scsi kernel modules reloaded. To have a stable address for the scsi_host adapter of scsi pool, this introduces new XMLs like: <adapter type='scsi_host' parent='pci_0000_00_1f_2' unique_id='5'/> Where "parent" is the parent device of the scsi host, it should be consistent with the name style what node device driver uses (Either udev backend style or HAL backend style), or the PCI address in format "domain:bus:slot:function" format. "unique_id" is the number exposed by sysfs.

[libvirt] [PATCH 0/5] Handling of undefine and redefine snapshots with VirtualBox 4.2
by Manuel VIVES 20 Jun '13

20 Jun '13

Hi, This is a serie of patches in order to support undefining and redefining snapshots with VirtualBox 4.2. The VirtualBox API provides only high level operations to manipulate snapshots, so it not possible to support flags like VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY with only API calls. Following an IRC talk with Eric Blake, the decision was taken to emulate these behaviours by manipulating directly the .vbox XML files. The first two patches are some util methods for handling uuid and strings that will be used after. The third patch brings more details in the snapshot XML returned by libvirt. We will need those modifications in order to redefine the snapshots. The fourth patch brings the support of the VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT flags in virDomainSnapshotCreateXML. The fifth and last patch brings the support of the VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY flag in virDomainSnapshotDelete. The patches are only for Virtualbox 4.2 Regards, Manuel VIVES Manuel VIVES (5): viruuid.h/c: Util method for finding uuid patterns in some strings virstring.h/c: Util method for making some find and replace in strings vbox_tmpl.c: Better XML description for snapshots vbox_tmpl.c: Patch for redefining snapshots vbox_tmpl.c: Add methods for undefining snapshots src/conf/domain_conf.c | 20 +- src/libvirt_private.syms | 2 + src/util/virstring.c | 129 ++++ src/util/virstring.h | 6 + src/util/viruuid.c | 79 ++ src/util/viruuid.h | 1 + src/vbox/vbox_tmpl.c | 1831 +++++++++++++++++++++++++++++++++++++++++++--- 7 files changed, 1943 insertions(+), 125 deletions(-) -- 1.7.10.4
