[PATCH v4 00/10] Introducing TPM Proxy device support for PPC64

changes in v4: - patch 1: added missing <code> tags - comma-escaped the path string in qemu_command.c (patch 8) - moved validations not-XML-parsing related from domain_conf.c to qemu_validate.c - new patches 3 and 4: cleanups - patch 5 (former 3): changed the approach to use a def->tpms array instead of def->tpmproxy pointer - new patch 6: qemu_validate changes to not clog patch 5 with changes - added Jano's and Stefan's r-b when applicable v3 link: https://www.redhat.com/archives/libvir-list/2020-May/msg00642.html v2 link: https://www.redhat.com/archives/libvir-list/2020-May/msg00604.html v1 link: https://www.redhat.com/archives/libvir-list/2020-May/msg00604.html Daniel Henrique Barboza (10): docs: documentation and schema for the new TPM Proxy model qemu: Extend QEMU capabilities with 'spapr-tpm-proxy' qemu_extdevice.c: remove unneeded 'ret' variable qemu_tpm, security, tests: change 'switch' clauses for 'if' conf, qemu, security, tests: introducing 'def->tpms' array qemu_validate.c: add validation for TPM Proxy model tests: add XML schema tests for the TPM Proxy device qemu: build command line for the TPM Proxy device tests/qemuxml2argvtest.c: add TPM Proxy command line tests docs/news.xml: update for the new TPM Proxy device docs/formatdomain.html.in | 19 ++++- docs/news.xml | 17 +++++ docs/schemas/domaincommon.rng | 1 + src/conf/domain_audit.c | 4 +- src/conf/domain_conf.c | 72 +++++++++++++----- src/conf/domain_conf.h | 6 +- src/qemu/qemu_alias.c | 9 ++- src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 3 + src/qemu/qemu_cgroup.c | 10 ++- src/qemu/qemu_command.c | 59 +++++++++++--- src/qemu/qemu_domain.c | 31 +++++--- src/qemu/qemu_domain_address.c | 11 ++- src/qemu/qemu_extdevice.c | 24 +++--- src/qemu/qemu_tpm.c | 76 +++++++++---------- src/qemu/qemu_validate.c | 19 +++++ src/security/security_dac.c | 8 +- src/security/security_selinux.c | 44 +++++------ src/security/virt-aa-helper.c | 14 ++-- .../qemucapabilitiesdata/caps_4.2.0.ppc64.xml | 1 + .../qemucapabilitiesdata/caps_5.0.0.ppc64.xml | 1 + tests/qemuxml2argvdata/ppc64-tpm-double.xml | 34 +++++++++ .../ppc64-tpmproxy-double.xml | 38 ++++++++++ .../ppc64-tpmproxy-single.ppc64-latest.args | 34 +++++++++ .../ppc64-tpmproxy-single.xml | 33 ++++++++ .../ppc64-tpmproxy-with-tpm.ppc64-latest.args | 37 +++++++++ .../ppc64-tpmproxy-with-tpm.xml | 36 +++++++++ tests/qemuxml2argvtest.c | 33 +++++--- .../ppc64-tpmproxy-single.ppc64-latest.xml | 42 ++++++++++ .../ppc64-tpmproxy-with-tpm.ppc64-latest.xml | 46 +++++++++++ tests/qemuxml2xmltest.c | 2 + 31 files changed, 616 insertions(+), 152 deletions(-) create mode 100644 tests/qemuxml2argvdata/ppc64-tpm-double.xml create mode 100644 tests/qemuxml2argvdata/ppc64-tpmproxy-double.xml create mode 100644 tests/qemuxml2argvdata/ppc64-tpmproxy-single.ppc64-latest.args create mode 100644 tests/qemuxml2argvdata/ppc64-tpmproxy-single.xml create mode 100644 tests/qemuxml2argvdata/ppc64-tpmproxy-with-tpm.ppc64-latest.args create mode 100644 tests/qemuxml2argvdata/ppc64-tpmproxy-with-tpm.xml create mode 100644 tests/qemuxml2xmloutdata/ppc64-tpmproxy-single.ppc64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/ppc64-tpmproxy-with-tpm.ppc64-latest.xml -- 2.26.2

QEMU 4.1.0 introduced a new device type called TPM Proxy, currently implemented by PPC64 guests via a new virtual device called 'spapr-tpm-proxy' (see QEMU 0fb6bd073230 for more info). The TPM Proxy device interacts with a TPM Resource Manager, a host device capable of multiplexing the host TPM with multiple processes. This allows multiple guests to access some TPM features at the same time. Note that this mode of operation does not provide full TPM features to be available for the guest - for that case the guest still needs to assign a vTPM device (tpm-spapr for PPC64 guests). Although redundant, there is currently no technical limitation for a guest to assign both a vTPM and a TPM Proxy at the same time. This patch adds documentation and schema for a new TPM model type called 'spapr-tpm-proxy' that creates this new TPM Proxy device. This model is valid only for the 'passthrough' backend. An example of a TPM Proxy device connected to a TPM Resource Manager '/dev/tpmrm0' will look like this: <tpm model='spapr-tpm-proxy'> <backend type='passthrough'> <device path='/dev/tpmrm0'/> </backend> </tpm> Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> --- docs/formatdomain.html.in | 19 ++++++++++++++++++- docs/schemas/domaincommon.rng | 1 + 2 files changed, 19 insertions(+), 1 deletion(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 23eb029234..15109e136c 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -8792,6 +8792,18 @@ qemu-kvm -net nic,model=? /dev/null backend device is a TPM 2.0. <span class="since">Since 6.1.0</span>, pSeries guests on PPC64 are supported and the default is <code>tpm-spapr</code>. + + <span class="since">Since 6.4.0</span>, a new model called + <code>spapr-tpm-proxy</code> was added for pSeries guests.

Expose the TPM Proxy support for PPC64 guests by creating a new cap called QEMU_CAPS_DEVICE_SPAPR_TPM_PROXY. This device is part of the machinery the guest need to orchestrate with the PPC64 Ultravisor the transition to the Secure VM (SVM) mode. Inside QEMU, this device will be used with the H_TPM_COMM hypercall to connect with the TPM Resource Manager, enabling the guest to open and close TPM sessions with the host TPM.

This trivial rework is aimed to reduce the amount of line changes made by the next patch, when 'def->tpm' will become a 'def->tpms' array. Instead of using a 'switch' where only the VIR_DOMAIN_TPM_TYPE_EMULATOR label does something, use an 'if' clause instead.

A TPM Proxy device can coexist with a regular TPM, but the current domain definition supports only a single TPM device in the 'tpm' pointer. This patch replaces this existing pointer in the domain definition to an array of TPM devices. All files that references the old pointer were adapted to handle the new array instead. virDomainDefParseXML() TPM related code was adapted to guarantee that the following combinations in the same domain are valid: - a single TPM device - a single TPM Proxy device - a single TPM + single TPM Proxy devices And, these combinations in the same domain are NOT valid: - 2 or more TPM devices - 2 or more TPM Proxy devices Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> --- src/conf/domain_audit.c | 4 +- src/conf/domain_conf.c | 72 ++++++++++++++++++++++++--------- src/conf/domain_conf.h | 6 ++- src/qemu/qemu_alias.c | 4 +- src/qemu/qemu_cgroup.c | 10 +++-- src/qemu/qemu_command.c | 34 +++++++++++----- src/qemu/qemu_domain.c | 31 +++++++++----- src/qemu/qemu_domain_address.c | 11 +++-- src/qemu/qemu_extdevice.c | 18 +++++---- src/qemu/qemu_tpm.c | 52 ++++++++++++++++++------ src/security/security_dac.c | 8 ++-- src/security/security_selinux.c | 32 +++++++++------ src/security/virt-aa-helper.c | 9 +++-- tests/qemuxml2argvtest.c | 13 +++--- 14 files changed, 208 insertions(+), 96 deletions(-) diff --git a/src/conf/domain_audit.c b/src/conf/domain_audit.c index 1b0abb21a0..8bc6633af4 100644 --- a/src/conf/domain_audit.c +++ b/src/conf/domain_audit.c @@ -821,8 +821,8 @@ virDomainAuditStart(virDomainObjPtr vm, const char *reason, bool success) for (i = 0;

This patch wraps it up all the wiring done in previous patches, enabling a PPC64 guest to launch a guest using a TPM Proxy device. Note that device validation is already being done in qemu_validate.c, qemuValidateDomainDeviceDefTPM(), on domain define time. We don't need to verify QEMU capabilities for this device again inside qemu_command.c.

Hi, This does not apply on current master anymore, so I'll need to rebase it. I'll take the opportunity to move the validation of a single TPM Proxy and a single regular TPM, that's being done inside domain_conf.c (patch 05), to a PostParse function inside qemu_domain.c. This way domain_conf.c will only handle the XML parsing. Only patches 05 and 06 will be affected. Thanks, DHB On 5/15/20 7:24 PM, Daniel Henrique Barboza wrote:
