[libvirt] [PATCH] daemonStreamHandleWriteData: Preserve error when aborting stream
by Michal Privoznik 14 Mar '18

14 Mar '18

The daemonStreamHandleWriteData() function is called whenever server side of stream is able to receive some data. Nevertheless, it calls virStreamSend() (to pass data down to virFDStream) and depending on its return value it may abort the stream. However, the functions it called when doing so are public APIs and as such reset any error set previously. Therefore, if there was any error in writing data to stream (i.e. repored in virStreamSend) it is reset before virNetServerProgramSendReplyError() can get to it.

[libvirt] [PATCH] virsysinfo: Use more virSkipSpacesBackwards()
by Michal Privoznik 14 Mar '18

14 Mar '18

Some fields reported by dmidecode have plenty of useless spaces (in fact some have nothing but spaces). To deal with this we have introduced virSkipSpacesBackwards() and use it in virSysinfoParseX86Processor() and virSysinfoParseX86Memory(). However, other functions (e.g. virSysinfoParseX86Chassis()) don't use it at all and thus we are reporting nonsense: <sysinfo type='smbios'> <chassis> <entry name='manufacturer'>FUJITSU</entry> <entry name='version'> </entry> <entry name='serial'> </entry> <entry name='asset'> </entry> <entry name='sku'>Default string</entry> </chassis> </sysinfo> Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/util/virsysinfo.c | 34 ++++++++++++++++++++++++++++++---- 1 file changed, 30 insertions(+), 4 deletions(-) diff --git a/src/util/virsysinfo.c b/src/util/virsysinfo.c index 43a4c8835..5795d90c7 100644 --- a/src/util/virsysinfo.c +++ b/src/util/virsysinfo.c @@ -644,7 +644,8 @@ static int virSysinfoParseBIOS(const char *base, virSysinfoBIOSDefPtr *bios) { int ret = -1;

[libvirt] [PATCH] qemu: avoid denial of service reading from QEMU guest agent (CVE-2018-1064)
by Daniel P. Berrangé 14 Mar '18

14 Mar '18

We read from the agent until seeing a \r\n pair to indicate a completed reply or event. To avoid memory denial-of-service though, we must have a size limit on amount of data we buffer. 10 MB is large enough that it ought to cope with normal agent replies, and small enough that we're not consuming unreasonable mem. This is identical to the flaw we had reading from the QEMU monitor as CVE-2018-5748, so rather embarrassing that we forgot to fix the agent code at the same time. Signed-off-by: Daniel P.

We use Python in out build system: more specifically, we're stuck with Python 2 even though Python 3's been out for a decade and some major Linux distributions have gone Python 3-only recently. This series tries to solve the issue, but falls quite short. Maybe someone who actually knows Python should have tried instead of me? The good news is that, once the first two patches have been merged, anyone will be able to give it a shot by running PYTHON=$(which python3) ./autogen.sh or similar. Let's get the ball rolling!

[libvirt] [PATCH] bugfix: add lock in ClientClose to avoid data race
by xinhua.Cao 13 Mar '18

13 Mar '18

From: l00425170 <liujunjie23(a)huawei.com> When libvirt client registers callback function, remoteDispatchConnectDomainEventCallbackRegisterAny is called, then virInsertElementsN will be called to add new callback for struct daemonClientPrivate *priv. But at the same time, if the corresponding socket is closed (one way is to kill the client process), the close callback remoteClientCloseFunc is called, then remoteFreePrivCallbacks(priv) is called to free priv. So there exists data race to cause libvirtd coredump. More details, in add callback, when memset for ptrptr (that is priv) is done in virExpandN at the process of virInsertElementsN. At this time point, priv can be free to be 0x0 when close client. So when the procedure goes to memcpy in virInsertElementsN, the libvirtd will coredump.

[libvirt] [PATCH] qemu: hotplug: fail when net device detach times out
by Jonathan Davies 13 Mar '18

13 Mar '18

qemuDomainDetachNetDevice should not treat a timeout in a call to qemuDomainWaitForDeviceRemoval as success. Instead, it should treat it as failure -- this is the intention behind having a timeout. If qemuDomainWaitForDeviceRemoval times out, it returns 0. In this instance, if qemuDomainDetachNetDevice returns 0, virsh detach-interface reports: Interface detached successfully with a zero exit status. But with a negative return value from qemuDomainDetachNetDevice, virsh detach-interface reports: error: Failed to detach interface error: An error occurred, but the cause is unknown with a non-zero exit status, which is more appropriate.

[libvirt] [PATCH v2 00/10] Add proper testing of qemu status XML files

Changes to v1: - added tests specifically for testing format probing (also formating of argv) - removed format probing from snapshot tests - added a synthetic test for <lockstate> - added <namespaces> to the 'modern' test (note that allowReboot is tested in one of the old tests which were preserved) This version also saves space by using symlinks in place of the output XML files since they are identical to the input ones in all cases added in this tests.

[libvirt] Two more libvirt GSOC ideas
by Erik Skultety 12 Mar '18

12 Mar '18

Hi, I'd like to add 2 more GSOC ideas to our wiki page, but I'd like to get some opinions whether you think these might even be appropriate GSOC project candidates. #1 PROJECT: Support wildcard with log filters SUMMARY: Enhance the log filters format to allow specifying a wildcard, i.e. <level>:* DESCRIPTION: Currently, libvirt admin interface allows (among other things) runtime tuning of daemon log settings with the exception of setting the global log priority. The main reason for not having an API to get/set the global log priority is that the same effect that setting global log level would have can be achieved with using log filters only which in terms of logging control provide us with more granularity. However, in order to achieve the same effect using filters only, one would end up with a filter similar to this: 1:access 1:daemon 1:conf 1:cpu 1:libvirt 1:locking 1:logging 1:network 1:nwfilter 1:util Therefore, we should enhance the format of a filter to allow us to simply use the following instead: 1:* other_filters #2 PROJECT: Extend node device driver's API set SUMMARY: Modify the existing set (adjust/add) of APIs for node device driver in order to provide similar functionality (conceptually) to other drivers. DESCRIPTION: The node device driver is responsible for host device management. In most cases, this means that we're simply just report device's capabilities and track its lifetime. This is enough for physical host devices, however, there are a few other virtualization features like NFV, NPIV, and MDEV where libvirt should also be able to create such virtual devices. Currently, libvirt is only able to create transient (temporary config) NPIV/vHBA devices, so besides having support for creating virtual functions and mediated devices on feature-capable physical device we also need to be able to store persistent configuration of such virtual devices. Besides extending the existing set of APIs, this will also require a certain amount of refactor of our current code base. Not all of the changes mentioned above are absolutely necessary to finish the project successfully. Thanks, Erik

[libvirt] [PATCH v2 0/9] x86: Secure Encrypted Virtualization (AMD)
by Brijesh Singh 12 Mar '18

12 Mar '18

This patch series provides support for launching an encrypted guest using AMD's new Secure Encrypted Virtualization (SEV) feature. SEV is an extension to the AMD-V architecture which supports running multiple VMs under the control of a hypervisor. When enabled, SEV feature allows the memory contents of a virtual machine (VM) to be transparently encrypted with a key unique to the guest VM. In order to launch SEV guest we need QEMU SEV patch [1]. [1] https://marc.info/?l=kvm&m=152051337301616&w=2 The patch series implements some of recommendation from Daniel [2] [2] https://www.redhat.com/archives/libvir-list/2017-September/msg00197.html At very high level the flow looks this: 1. mgmt tool calls virConnectGetDomainCapabilities. This returns an XML document that includes the following <feature> ... <sev supported='yes'> <cbitpos> </cbitpos> <reduced-phys-bits> </reduced-phys-bits> <pdh> </pdh> <cert-chain> </cert-chain> </feature> If <sev> is provided then we indicate that hypervisor is capable of launching SEV guest. 2. (optional) mgmt tool can provide the PDH and Cert-chain to guest owner in case if guest owner wish to establish a secure connection with SEV firmware to negotiate a key used for validating the measurement. 3. mgmt tool requests to start a guest calling virCreateXML(), passing VIR_DOMAIN_START_PAUSED. The xml would include <launch-security type='sev'> <cbitpos> </cbitpos> /* the value is same as what is obtained via virConnectGetDomainCapabilities() <reduced-phys-bits> </reduced-phys-bits> /* the value is same as what is obtained via virConnectGetDomainCapabilities() <dh-cert> .. </dh> /* guest owners diffie-hellman key */ (optional) <session> ..</session> /* guest owners session blob */ (optional) <policy> ..</policy> /* guest policy */ (optional) 4. Libvirt generate the QEMU cli arg to enable the SEV feature, a typical args looks like this: # $QEMU .. -machine memory-encryption=sev0 \ -object sev-guest,id=sev0,dh-cert-file=<file>.... 5. Libvirt generates lifecycle VIR_DOMAIN_EVENT_SUSPENDED_PAUSED event 6. mgmt tool gets the VIR_DOMAIN_EVENT_SUSPENDED_PAUSED and calls virDomainGetLaunchSecretInfo() to retrieve the measurement of encrypted memory. 7. (optional) mgmt tool can provide the measurement value to guest owner, which can validate the measurement and gives GO/NO-GO answer. If mgmt tool gets GO then it resumes the guest otherwise it calls destroy() to kill the guest. 8. mgmt tool resumes the guest TODO: * SEV guest require to use DMA apis for the virtio devices. In order to use the DMA apis the virtio devices must have this tag <driver iommu=on ats=on> It is a bit unclear to me where these changes need to go. Do we need to modify the libvirt to automatically add these when SEV is enabled or we ask mgmt tool to make sure that it creates XML with right tag to enable the DMA APIs for virtio devices. I am looking for some suggestions. Using these patches we have succesfully booted and tested a guest both with and without SEV enabled. SEV Firmware API spec is available at: https://support.amd.com/TechDocs/55766_SEV-KM%20API_Specification.pdf Changes since v1: * rename <sev> -> <launch-security> for domain * add more information about policy and other fields in domaincaps.html * split the domain_conf support in two patches * add virDomainGetLaunchInfo() to retrieve the SEV measurement * extend virsh command to show the domain's launch security information * add test cases to validate newly added <launch-security> element * fix issues reported with 'make check' and 'make syntax-check' The complete git tree is available at: https://github.com/codomania/libvirt/tree/v2 Brijesh Singh (8): qemu: provide support to query the SEV capability qemu: introduce SEV feature in hypervisor capabilities conf: introduce launch-security element in domain qemu: add support to launch SEV guest libvirt: add new public API to get launch security info remote: implement the remote protocol for launch security qemu_driver: add support to launch security info virsh: implement new command for launch security Xiaogang Chen (1): tests: extend tests to include sev specific tag parsing docs/formatdomain.html.in | 120 ++++++++++++++++++++++++++++++++++++ docs/formatdomaincaps.html.in | 40 ++++++++++++ docs/schemas/domaincaps.rng | 20 ++++++ docs/schemas/domaincommon.rng | 39 ++++++++++++ include/libvirt/libvirt-domain.h | 17 +++++ src/conf/domain_capabilities.c | 20 ++++++ src/conf/domain_capabilities.h | 14 +++++ src/conf/domain_conf.c | 111 +++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 27 ++++++++ src/driver-hypervisor.h | 7 +++ src/libvirt-domain.c | 50 +++++++++++++++ src/libvirt_public.syms | 5 ++ src/qemu/qemu_capabilities.c | 45 ++++++++++++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_capspriv.h | 4 ++ src/qemu/qemu_command.c | 33 ++++++++++ src/qemu/qemu_driver.c | 72 ++++++++++++++++++++++ src/qemu/qemu_monitor.c | 17 +++++ src/qemu/qemu_monitor.h | 6 ++ src/qemu/qemu_monitor_json.c | 105 +++++++++++++++++++++++++++++++ src/qemu/qemu_monitor_json.h | 5 ++ src/qemu/qemu_process.c | 91 +++++++++++++++++++++++++++ src/remote/remote_daemon_dispatch.c | 63 +++++++++++++++++++ src/remote/remote_driver.c | 52 +++++++++++++++- src/remote/remote_protocol.x | 22 ++++++- src/remote_protocol-structs | 13 ++++ tests/genericxml2xmlindata/sev.xml | 22 +++++++ tests/genericxml2xmloutdata/sev.xml | 22 +++++++ tests/genericxml2xmltest.c | 2 + tests/qemuxml2argvdata/sev.args | 25 ++++++++ tests/qemuxml2argvdata/sev.xml | 35 +++++++++++ tests/qemuxml2argvtest.c | 2 + tests/qemuxml2xmloutdata/sev.xml | 39 ++++++++++++ tests/qemuxml2xmltest.c | 2 + tools/virsh-domain.c | 93 ++++++++++++++++++++++++++++ 35 files changed, 1239 insertions(+), 2 deletions(-) create mode 100644 tests/genericxml2xmlindata/sev.xml create mode 100644 tests/genericxml2xmloutdata/sev.xml create mode 100644 tests/qemuxml2argvdata/sev.args create mode 100644 tests/qemuxml2argvdata/sev.xml create mode 100644 tests/qemuxml2xmloutdata/sev.xml -- 2.14.3

[libvirt] libvirt-snmp status
by Michael Corcoran 12 Mar '18

12 Mar '18

Hi All, I'd like to enquire about the status of libvirt-snmp. It hasn't had any commits for a couple of years and no longer compiles against recent versions of net-snmp. As I understand it, upstream net-snmp deprecated and then removed the C type "U64" as it conflicts with Perl. Fortunately this is the only issue and the patch required to get libvirt-snmp building again simply replaces the C type "U64" with the type "struct counter64" in a few places. I tried to submit a patch but was unable to configure authentication/encryption correctly for git send-email and I'm unwilling to spend more time on it. Is there any way to accept patches directly from Github (or anywhere else I can push a commit)? My second enquiry relates to the org OID used in the LIBVIRT-MIB. It currently uses a (presumably) placeholder of 12345. I check the OID register[1] and found an entry for libvirt (see end of email). I am guessing that registration didn't go through until after libvirt-snmp maintenance stopped. I'd like to submit a patch to replace the placeholder with this org id also. BR, Michael Corcoran [1] https://www.iana.org/assignments/enterprise-numbers/enterprise-numb ers 36957 libvirt Daniel Veillard daniel&veillard.com

[libvirt] [PATCH v7 00/11] qemu: Validate PCI controller options
by Andrea Bolognani 09 Mar '18

09 Mar '18

Applies cleanly on top of b932ed69f6664f42e211bdde84c8ab04e1f19033. Patches 2/11 and 4/11 are the only ones missing R-bs, everything else hasn't been significantly altered since [v5]. Changes from [v6]: * don't special-case the default PHB when checking capabilities. Changes from [v5]: * patch 1 has been pushed; * add virReportController*() functions to cut down on redundant error reporting, as suggested by laine; * report index and modelName along with model in error messages. Changes from [v4]: * patch 1/12 is new; * use virReportEnumRangeError(), as suggested by laine. Changes from [v3]: * don't introduce new test cases that won't be able to provide full test coverage anyway, as suggested by laine. Changes from [v2]: * replace the old implementation bit by bit using a clever trick suggested by pkrempa; * don't move QEMU capability validation; * add a default: label to all switch statements as recommended by danpb. Changes from [v1]: * error out instead of silently accept invalid options; * shave quite a lot of yaks.

[libvirt] [PATCH v2 00/12] Basic implementation of persistent reservations
by Michal Privoznik 09 Mar '18

09 Mar '18

v2 of: https://www.redhat.com/archives/libvir-list/2018-January/msg00584.html diff to v1: - Dropped the hash table and stayed with simple pid_t in vm->privateData - Couple of small fixes (basically to address Peter's review) What is still missing: - Event from qemu when the helper process dies (in my testing, qemu process dies as soon as it tries to do PR). - <hostdev/> support, which surprisingly works even without these patches. I mean, if I add the following hostdev the guest is already able to do PR even with plain origin/master: <hostdev mode='subsystem' type='scsi' managed='no' rawio='no'> <source> <adapter name='scsi_host7'/> <address bus='0' target='0' unit='0'/> </source> <address type='drive' controller='0' bus='0' target='0' unit='4'/> </hostdev> where host7 is an iSCSI device: /sys/bus/scsi/devices/7\:0\:0\:0/block/sdd/ and the part of generated cmd line: -drive file=/dev/sg3,if=none,id=drive-hostdev0 \ -device scsi-generic,bus=scsi0.0,channel=0,scsi-id=0,lun=4,drive=drive-hostdev0,id=hostdev0 However, the qemu is running under my regular user nor it has any special capabilities: # grep -e "^Name" -e "^Uid" -e "^Gid" -e "^Cap" /proc/$(pgrep qemu)/status Name: qemu-system-x86 Uid: 1000 1000 1000 1000 Gid: 1000 1000 1000 1000 CapInh: 0000000000000000 CapPrm: 0000000000000000 CapEff: 0000000000000000 CapBnd: 0000003fffffffff CapAmb: 0000000000000000 As usual, you can find the patches on my github too: https://github.com/zippy2/libvirt/tree/pr_v2 Michal Privoznik (12): virstoragefile: Introduce virStoragePRDef qemuDomainDiskChangeSupported: Deny changing reservations qemu: Introduce pr-manager-helper capability qemu: Generate alias and socket path for pr-helper qemu: Store pr runtime data in status XML qemu: Generate cmd line at startup qemu: Introduce pr_helper to qemu.conf qemu_domain: Track pr-helper PID in status XML qemu: Start PR daemons on domain startup qemu_hotplug: Hotplug of reservations qemu_hotplug: Hotunplug of reservations qemu: Detect pr-manager-helper capability docs/formatdomain.html.in | 25 ++- docs/schemas/domaincommon.rng | 34 +--- docs/schemas/storagecommon.rng | 50 +++++ m4/virt-driver-qemu.m4 | 5 + src/conf/domain_conf.c | 36 ++++ src/libvirt_private.syms | 6 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 4 + src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 40 ++++ src/qemu/qemu_conf.c | 7 +- src/qemu/qemu_conf.h | 1 + src/qemu/qemu_domain.c | 213 ++++++++++++++++++++- src/qemu/qemu_domain.h | 15 ++ src/qemu/qemu_hotplug.c | 94 +++++++++ src/qemu/qemu_process.c | 188 ++++++++++++++++++ src/qemu/qemu_process.h | 7 + src/qemu/test_libvirtd_qemu.aug.in | 1 + src/util/virstoragefile.c | 181 +++++++++++++++++ src/util/virstoragefile.h | 19 ++ .../disk-virtio-scsi-reservations-not-managed.args | 28 +++ .../disk-virtio-scsi-reservations-not-managed.xml | 40 ++++ .../disk-virtio-scsi-reservations.args | 29 +++ .../disk-virtio-scsi-reservations.xml | 38 ++++ tests/qemuxml2argvtest.c | 8 + .../disk-virtio-scsi-reservations-not-managed.xml | 1 + .../disk-virtio-scsi-reservations.xml | 1 + tests/qemuxml2xmltest.c | 4 + 29 files changed, 1042 insertions(+), 37 deletions(-) create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations-not-managed.args create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations-not-managed.xml create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations.args create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations.xml create mode 120000 tests/qemuxml2xmloutdata/disk-virtio-scsi-reservations-not-managed.xml create mode 120000 tests/qemuxml2xmloutdata/disk-virtio-scsi-reservations.xml -- 2.16.1

[libvirt] [PATCH] apparmor: add ro rule for sasl GSSAPI plugin on /etc/gss/mech.d/
by Christian Ehrhardt 08 Mar '18

08 Mar '18

If a system has sasl GSSAPI plugin available qemu with sasl support will try to read /etc/gss/mech.d/. It is required to allow that to let the modules fully work and it should be safe to do so as it only registers/configures plugins but has no secrets.

[libvirt] Libvirt and Vmware support
by Egoitz Aurrekoetxea 08 Mar '18

08 Mar '18

Good morning, I had the intention to integrate Libvirt with Xen, Vmware and KVM. We are in process of migrating to KVM but needed to integrate for some time VMware mainly. Does it support or are plans to, support Vmware ESX/Vcenter 6.X?. Best regards, -- sarenet *Egoitz Aurrekoetxea* Departamento de sistemas 944 209 470 Parque Tecnológico.

[libvirt] [PATCH 0/4] travis: Various improvements
by Andrea Bolognani 08 Mar '18

08 Mar '18

Basically my own spin on https://www.redhat.com/archives/libvir-list/2018-February/msg01106.html Patch 3/4 is actually carried over unchanged from that series. The upstart bit is missing because I'm not too sure about how to deal with it, but it can be solved as a follow-up anyway.

This is a workaround for the bizarre behaviour whereby the kernel throws away all fcntl() locks on execve()... if any threads are running. We simply make virtlockd & virlogd single threaded instead.

I'm not really sure how to best fix this deadlock. One hack that avoids the deadlock is to load the nwfilter driver after the hypervisor drivers, as the below patch does. This is obviously problematic if loading a hypervisor driver requires the nwfilter one. Any suggestions on better fixes for this issue?
