[libvirt] [v11 0/6] Write separate module for hostdev passthrough

by Chunyan Liu

These patches implements a separate module for hostdev passthrough so that it could be shared by different drivers and can maintain a global state of a host device. patch 1/6: extract hostdev passthrough function from qemu_hostdev.c and make it reusable by multiple drivers. patch 2/6: add a unit test for hostdev common library. patch 3/6: switch qemu driver to use the common library instead of its own hostdev passthrough APIs. patch 4/6: switch lxc driver to use the common library instead of its own hostdev passthrough APIs. patch 5/6: add a hostdev pci backend type for xen usage. patch 6/6: add pci passthrough to libxl driver. --- Changes * rebase to lastest changes in src/util/virscsi.c, src/qemu/qemu_process.c, tests/virpcimock.c, etc. Chunyan Liu (6): add hostdev passthrough common library add unit test for hostdev common library change qemu driver to use hostdev common library change lxc driver to use hostdev common library add hostdev pci backend type for xen add pci passthrough to libxl driver docs/schemas/domaincommon.rng | 1 + po/POTFILES.in | 3 +- src/Makefile.am | 3 +- src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/libvirt_private.syms | 21 + src/libxl/libxl_conf.c | 63 + src/libxl/libxl_conf.h | 4 + src/libxl/libxl_domain.c | 9 + src/libxl/libxl_driver.c | 448 +++++- src/lxc/lxc_conf.h | 4 - src/lxc/lxc_driver.c | 47 +- src/lxc/lxc_hostdev.c | 413 ----- src/lxc/lxc_hostdev.h | 43 - src/lxc/lxc_process.c | 24 +- src/qemu/qemu_command.c | 4 +- src/qemu/qemu_conf.h | 9 +- src/qemu/qemu_domain.c | 22 + src/qemu/qemu_driver.c | 81 +- src/qemu/qemu_hostdev.c | 1457 ----------------- src/qemu/qemu_hostdev.h | 76 - src/qemu/qemu_hotplug.c | 136 +- src/qemu/qemu_process.c | 40 +- src/util/virhostdev.c | 1706 ++++++++++++++++++++ src/util/virhostdev.h | 134 ++ src/util/virpci.c | 30 +- src/util/virpci.h | 9 +- src/util/virscsi.c | 28 +- src/util/virscsi.h | 8 +- src/util/virusb.c | 29 +- src/util/virusb.h | 8 +- tests/Makefile.am | 5 + .../qemuxml2argv-hostdev-pci-address.xml | 1 + .../qemuxml2argvdata/qemuxml2argv-net-hostdev.xml | 1 + tests/qemuxml2argvdata/qemuxml2argv-pci-rom.xml | 2 + tests/virhostdevtest.c | 473 ++++++ 36 files changed, 3132 insertions(+), 2214 deletions(-) delete mode 100644 src/lxc/lxc_hostdev.c delete mode 100644 src/lxc/lxc_hostdev.h delete mode 100644 src/qemu/qemu_hostdev.c delete mode 100644 src/qemu/qemu_hostdev.h create mode 100644 src/util/virhostdev.c create mode 100644 src/util/virhostdev.h create mode 100644 tests/virhostdevtest.c

[libvirt] [PATCH] event: move event filtering to daemon (regression fix)

by Eric Blake

Commit f9f56340 for CVE-2014-0028 almost had the right idea - we need to check the ACL rules to filter which events to send. But it overlooked one thing: the event dispatch queue is running in the main loop thread, and therefore does not normally have a current virIdentityPtr. But filter checks can be based on current identity, so when libvirtd.conf contains access_drivers=["polkit"], we ended up rejecting access for EVERY event due to failure to look up the current identity, even if it should have been allowed. Furthermore, even for events that are triggered by API calls, it is important to remember that the point of events is that they can be copied across multiple connections, which may have separate identities and permissions. So even if events were dispatched from a context where we have an identity, we must change to the correct identity of the connection that will be receiving the event, rather than basing a decision on the context that triggered the event, when deciding whether to filter an event to a particular connection. If there were an easy way to get from virConnectPtr to the appropriate virIdentityPtr, then object_event.c could adjust the identity prior to checking whether to dispatch an event. But setting up that back-reference is a bit invasive. Instead, it is easier to delay the filtering check until lower down the stack, at the point where we have direct access to the RPC client object that owns an identity. As such, this patch ends up reverting a large portion of the framework of commit f9f56340. We also have to teach 'make check' to special-case the fact that the event registration filtering is done at the point of dispatch, rather than the point of registration. Note that even though we don't actually use virConnectDomainEventRegisterCheckACL (because the RegisterAny variant is sufficient), we still generate the function for the purposes of documenting that the filtering takes place. Also note that I did not entirely delete the notion of a filter from object_event.c; I still plan on using that for my upcoming patch series for qemu monitor events in libvirt-qemu.so. In other words, while this patch changes ACL filtering to live in remote.c and therefore we have no current client of the filtering in object_event.c, the notion of filtering in object_event.c is still useful down the road. * src/check-aclrules.pl: Exempt event registration from having to pass checkACL filter down call stack. * daemon/remote.c (remoteRelayDomainEventCheckACL) (remoteRelayNetworkEventCheckACL): New functions.

[libvirt] [PATCH] network: disallow <bandwidth>/<mac> for bridged/macvtap networks

by Laine Stump

https://bugzilla.redhat.com/show_bug.cgi?id=1057321 pointed out that we weren't honoring the <bandwidth> element in libvirt networks using <forward mode='bridge'/>. In fact, these networks are just a method of giving a libvirt network name to an existing Linux host bridge on the system, and even if it were technically possible for us to set network-wide bandwidth limits for all the taps on a bridge, it's probably not a polite thing to do since libvirt is just using a bridge that was created by someone else for other purposes. So the proper thing is to just log an error when someone tries to put a <bandwidth> element in that type of network. While looking through the network XML documentation and comparing it to the networkValidate function, I noticed that we also ignore the presence of a mac address in the config, even though we do nothing with it in this case either. This patch updates networkValidate() (which is called any time a persistent network is defined, or a transient network created) to log an error and fail if it finds either a <bandwidth> or <mac> element and the network forward mode is anything except 'route'. 'nat', or nothing. (Yes, neither of those elements is acceptable for any macvtap mode, nor for a hostdev network). NB: This does *not* cause failure to start any existing network that contains one of those elements, so someone might have erroneously defined such a network in the past, and that network will continue to function unmodified. I considered it too disruptive to suddenly break working configs on the next reboot after a libvirt upgrade. --- src/network/bridge_driver.c | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 0b43a67..3b9b58d 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -2407,8 +2407,17 @@ networkValidate(virNetworkDriverStatePtr driver, virNetworkSetBridgeMacAddr(def); } else { /* They are also the only types that currently support setting - * an IP address for the host-side device (bridge) + * a MAC or IP address for the host-side device (bridge), DNS + * configuration, or network-wide bandwidth limits. */ + if (def->mac_specified) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("Unsupported <mac> element in network %s " + "with forward mode='%s'"), + def->name, + virNetworkForwardTypeToString(def->forward.type)); + return -1; + } if (virNetworkDefGetIpByIndex(def, AF_UNSPEC, 0)) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, _("Unsupported <ip> element in network %s " @@ -2433,6 +2442,14 @@ networkValidate(virNetworkDriverStatePtr driver, virNetworkForwardTypeToString(def->forward.type)); return -1; } + if (def->bandwidth) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("Unsupported network-wide <bandwidth> element " + "in network %s with forward mode='%s'"), + def->name, + virNetworkForwardTypeToString(def->forward.type)); + return -1; + } } /* We only support dhcp on one IPv4 address and -- 1.8.5.3

[libvirt] [PATCH] qemu: Fix crash in virDomainMemoryStats with old qemu

by Jiri Denemark

If virDomainMemoryStats was run on a domain with virtio balloon driver running on an old qemu which supports QMP but does not support qom-list QMP command, libvirtd would crash. The reason is we did not check if qemuMonitorJSONGetObjectListPaths failed and moreover we even stored its result in an unsigned integer type.
