[libvirt] [PATCH 00/13] PCI passthrough support on s390
by Xiao Feng Ren 08 Jun '18

08 Jun '18

The PCI representation in QEMU has recently been extended for S390 allowing configuration of zPCI attributes like uid (user-defined identifier) and fid (PCI function identifier). The details can be found here: https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg07262.html To support the new zPCI feature of the S390 platform, two new XML attributes, @uid and @fid, are introduced for device addresses of type 'pci', i.e.: <hostdev mode='subsystem' type='pci'> <driver name='vfio'/> <source> <address domain='0x0001' bus='0x00' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0' uid='0x0003' fid='0x00000027'/> </hostdev> uid and fid are optional attributes. If they are defined by the user, unique values within the guest domain must be used. If they are not specified and the architecture requires them, they are automatically generated with non-conflicting values. Current implementation is the most seamless one for the user as it unites the address specific data of a PCI device on one XML element. It could accommodate both specifying our special parameters (uid and fid) and re-using standard statements (domain, bus, slot and function) for PCI devices. User can still specify bus/slot/function for the virtualized PCI devices in the XML. Thus uid/fid act as an extension to the PCI address and are stored in a new structure 'virZPCIDeviceAddress' which is a member of common PCI Address structure. Additionally, two hashtables are used for assignment and reservation of uid/fid. In support of extending the PCI address, a new PCI address extension flag is introduced. This extension flag allows is not only dedicated for the S390 platform but also other architectures needing certain extensions to PCI address space.

[libvirt] [PATCH v8 0/9] x86: Secure Encrypted Virtualization (AMD)
by Brijesh Singh 07 Jun '18

07 Jun '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. 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> </sev> </feature> If <sev> is provided then we indicate that hypervisor is capable of launching SEV guest. mgmt tool can call virNodeGetSEVCapabilities() to get the additional informations like PDH and certificate chain etc. 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>47</cbitpos> <reduced-phys-bits>1</reduced-phys-bits> <policy>0x1</policy> (optional) <dh-cert> </dh-cert> /* Guest owners Diffie-Hellman key */ <session> </session> /* Guest owners Session blob */ </launch-security> 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 Change since v7: * rename virNodeSEVCapability() -> virNodeSEVInfo() * rebase the series Changes since v6: * add API to get SEV PDH and Certificate chain data * drop virsh command changes. We can revisit this later when we have more visibility on setter. Change since v5: * drop the seperate test patch and merge the code with other patches. * rename the xml from sev -> launch-security-sev * make policy field mandatory * address multiple feedback from previous reviews. Changes since v4: * add /dev/sev in shared device list Changes since v3: * rename QEMU_CAPS_SEV -> QEMU_CAPS_SEV_GUEST * update caps_2.12.0.x86_64.replies to include query-sev-capabilities data Changes since v2: * make cbitpos, policy and reduced-phys-bits as unsigned int * update virDomainGetLaunchSecurityInfo to accept virTypedParameterPtr *params instead of virTypedParameterPtr params. 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/v8 Brijesh Singh (11): qemu: provide support to query the SEV capability conf: expose SEV feature in domain capabilities libvirt: add new public API to get SEV Info remote: implement the remote protocol for virNodeSEVInfo() qemu: Add support to get the SEV info conf: introduce launch-security element in domain qemu/cgroup: add /dev/sev in shared devices list 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: Add support to launch security info docs/drvqemu.html.in | 1 + docs/formatdomain.html.in | 115 +++++++++++++++ docs/formatdomaincaps.html.in | 30 ++++ docs/schemas/domaincaps.rng | 14 ++ docs/schemas/domaincommon.rng | 37 +++++ include/libvirt/libvirt-domain.h | 17 +++ include/libvirt/libvirt-host.h | 42 ++++++ src/conf/domain_capabilities.c | 31 +++- src/conf/domain_capabilities.h | 17 +++ src/conf/domain_conf.c | 133 +++++++++++++++++ src/conf/domain_conf.h | 27 ++++ src/driver-hypervisor.h | 14 ++ src/libvirt-domain.c | 48 +++++++ src/libvirt-host.c | 47 ++++++ src/libvirt_private.syms | 2 +- src/libvirt_public.syms | 2 + src/qemu/qemu.conf | 2 +- src/qemu/qemu_capabilities.c | 90 +++++++++++- src/qemu/qemu_capabilities.h | 4 + src/qemu/qemu_capspriv.h | 4 + src/qemu/qemu_cgroup.c | 2 +- src/qemu/qemu_command.c | 41 ++++++ src/qemu/qemu_driver.c | 160 +++++++++++++++++++++ src/qemu/qemu_monitor.c | 18 +++ src/qemu/qemu_monitor.h | 6 + src/qemu/qemu_monitor_json.c | 121 ++++++++++++++++ src/qemu/qemu_monitor_json.h | 5 + src/qemu/qemu_process.c | 62 ++++++++ src/qemu/test_libvirtd_qemu.aug.in | 1 + src/remote/remote_daemon_dispatch.c | 91 ++++++++++++ src/remote/remote_driver.c | 80 +++++++++++ src/remote/remote_protocol.x | 39 ++++- src/remote_protocol-structs | 24 ++++ tests/genericxml2xmlindata/launch-security-sev.xml | 24 ++++ tests/genericxml2xmltest.c | 2 + .../caps_2.12.0.x86_64.replies | 10 ++ tests/qemucapabilitiesdata/caps_2.12.0.x86_64.xml | 3 +- tests/qemuxml2argvdata/launch-security-sev.args | 29 ++++ tests/qemuxml2argvdata/launch-security-sev.xml | 37 +++++ tests/qemuxml2argvtest.c | 4 + 40 files changed, 1429 insertions(+), 7 deletions(-) create mode 100644 tests/genericxml2xmlindata/launch-security-sev.xml create mode 100644 tests/qemuxml2argvdata/launch-security-sev.args create mode 100644 tests/qemuxml2argvdata/launch-security-sev.xml -- 2.7.4

[libvirt] [PATCH v9 00/17] Add support for TPM emulator
by Stefan Berger 07 Jun '18

07 Jun '18

This series of patches adds support for the TPM emulator backend that is available in QEMU and based on swtpm + libtpms. It allows to attach a TPM 1.2 or 2.0 to a QEMU VM. sVirt labels are used for labeling the swtpm process, its Unix socket, and log file with the same label that the QEMU process gets. Besides that swtpm is added to the emulator cgroup to restrict its CPU usage. The device XML can be changed from a TPM 1.2 to a TPM 2.0 and back to a TPM 1.2. The device state is not removed during those changes but only when the domain is undefined. The swtpm needs persistent storage to store its state. For that I am using the uuid of the VM as part of the path since the name of the VM can be changed. Logfiles, PID files, and socket names are based on the name of the VM, though. Stefan v8->v9: - changed TPM 2 to 2.0 and version='2' in XML to version='2.0' - squashed v8 15/18 patch into v9 10/17. - Followed Ján Tomko's suggestions - updated AppArmor related patch v7->v8: - Delaying this series for 4.5; adjusted references to 4.4 - Fixed a test case since version='1.2' is now formatted as well - Appended patches for AppArmor and auditing - Appended patches that improve / fix existing code - patch for validating the TPM configuration rather than overwriting it; a particular case is the CRB interface does not work with a TPM 1.2 - swtpm_setup can be run for a TPM 2 in unprivileged mode as well v6->v7: - followed Jan Tomko's suggestion with resulting changing to patch 10/12. - re-added missing parts related to swtpm_setup and TPM that got lost in v4 v5->v6: - Addressed John Ferlan's comments - rebased on latest tip - Added patch 12. v4->v5: - Addressed John Ferlan's, Boris Fiuczysnki's and Marc Hartmayer's comments - rebased on latest tip v3->v4: - Addressed John Ferlan's comments - Fixed bugs I found while testing - rebased on latest tip Stefan Berger (17): conf: Add support for external swtpm TPM emulator to domain XML qemu: Extend QEMU capabilities with 'tpm-emulator' util: Implement virFileChownFiles() security: Add DAC and SELinux security for tpm-emulator qemu: Extend qemu_conf with tpm-emulator support qemu: Extend QEMU with external TPM support qemu: Add support for external swtpm TPM emulator tests: Add test cases for external swtpm TPM emulator security: Label the external swtpm with SELinux labels conf: Add support for choosing emulation of a TPM 2.0 qemu: Add swtpm to emulator cgroup news: Update news with new TPM emulator feature security: Add swtpm paths to the domain's AppArmor profile qemu: Run swtpm_setup in unprivileged mode for a TPM 2.0 conf: Audit TPM emulator device at domain startup conf: Use resrc=tpm in case of TPM passthrough following docs conf: Use virDomainChrSourceDefClear() rather than VIR_FREE() docs/auditlog.html.in | 2 +- docs/formatdomain.html.in | 47 +- docs/news.xml | 13 + docs/schemas/domaincommon.rng | 17 + examples/apparmor/libvirt-qemu | 3 + libvirt.spec.in | 2 + src/conf/domain_audit.c | 20 +- src/conf/domain_conf.c | 56 +- src/conf/domain_conf.h | 16 + src/libvirt_private.syms | 3 + src/qemu/Makefile.inc.am | 10 + src/qemu/libvirtd_qemu.aug | 5 + src/qemu/qemu.conf | 8 + src/qemu/qemu_capabilities.c | 5 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 36 + src/qemu/qemu_cgroup.h | 2 + src/qemu/qemu_command.c | 34 +- src/qemu/qemu_conf.c | 43 + src/qemu/qemu_conf.h | 6 + src/qemu/qemu_domain.c | 36 +- src/qemu/qemu_extdevice.c | 180 ++++ src/qemu/qemu_extdevice.h | 59 ++ src/qemu/qemu_process.c | 16 + src/qemu/qemu_security.c | 69 ++ src/qemu/qemu_security.h | 11 + src/qemu/qemu_tpm.c | 925 +++++++++++++++++++++ src/qemu/qemu_tpm.h | 56 ++ src/qemu/test_libvirtd_qemu.aug.in | 2 + src/security/security_dac.c | 7 + src/security/security_driver.h | 7 + src/security/security_manager.c | 36 + src/security/security_manager.h | 6 + src/security/security_selinux.c | 172 ++++ src/security/security_stack.c | 40 + src/security/virt-aa-helper.c | 45 + src/util/virfile.c | 55 ++ src/util/virfile.h | 3 + tests/qemucapabilitiesdata/caps_2.11.0.s390x.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.aarch64.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.ppc64.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.s390x.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.x86_64.xml | 1 + .../tpm-emulator-tpm2.x86_64-latest.args | 33 + tests/qemuxml2argvdata/tpm-emulator-tpm2.xml | 30 + .../tpm-emulator.x86_64-latest.args | 33 + tests/qemuxml2argvdata/tpm-emulator.xml | 30 + tests/qemuxml2argvtest.c | 16 +- tests/qemuxml2xmloutdata/tpm-emulator-tpm2.xml | 34 + tests/qemuxml2xmloutdata/tpm-emulator.xml | 34 + tests/qemuxml2xmltest.c | 1 + 51 files changed, 2251 insertions(+), 19 deletions(-) create mode 100644 src/qemu/qemu_extdevice.c create mode 100644 src/qemu/qemu_extdevice.h create mode 100644 src/qemu/qemu_tpm.c create mode 100644 src/qemu/qemu_tpm.h create mode 100644 tests/qemuxml2argvdata/tpm-emulator-tpm2.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/tpm-emulator-tpm2.xml create mode 100644 tests/qemuxml2argvdata/tpm-emulator.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/tpm-emulator.xml create mode 100644 tests/qemuxml2xmloutdata/tpm-emulator-tpm2.xml create mode 100644 tests/qemuxml2xmloutdata/tpm-emulator.xml -- 2.14.3

[libvirt] [PATCH] docs: remove git snapshot download links
by Daniel P. Berrangé 07 Jun '18

07 Jun '18

The process used to build the snapshots no longer works because the box it runs on is outdated. Analysing the web logs shows the majority of traffic to these links is from search engine bots. With those removed, there is about 1 hit per day from (probable) humans. Most users needing a tarball are better served by using official releases. Those needing latest code are better served by using git checkout. The tarball snapshots are not compelling enough to invest time in fixing the script that produces them. Signed-off-by: Daniel P. Berrangé <berrange(a)redhat.com> --- NB when pushing this, I would delete the existing files from the download location so we aren't left with stale files, and disable the (now broken) cronjob. docs/downloads.html.in | 15 --------------- 1 file changed, 15 deletions(-) diff --git a/docs/downloads.html.in b/docs/downloads.html.in index 2956a4f60e..657cd6a6f8 100644 --- a/docs/downloads.html.in +++ b/docs/downloads.html.in @@ -433,21 +433,6 @@ <li><a href="https://libvirt.org/sources/">libvirt.org HTTPS server</a></li> </ul> - <h2><a id="hourly">Hourly development snapshots</a></h2> - - <p> - Once an hour, an automated snapshot is made from the git server - source tree.
