[libvirt] [PATCH v2 0/4] Fix a SIGSEGV in libvirtd when querying AMD SEV info
This series fixes the following BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1612009 TL;DR: We don't format SEV platform data (PDH, certificate chain,...) into our qemu caps cache which poses a problem after libvirtd restart when we restore from the cache and get a segfault upon issuing virNodeGetSEVInfo. Since v1: - reworked patch 3 so that qemuMonitorJSONGetSEVCapabilities returns more values in order to distinguish between error and whether SEV is actually supported - added the missing backtrace to patch 4 - no other patches were changed apart from patch 3 Erik Skultety (4): tests: sev: Test launch-security with specific QEMU version qemu: Define and use a auto cleanup function with virSEVCapability qemu: Fix probing of AMD SEV support qemu: caps: Format SEV platform data into qemuCaps cache src/conf/domain_capabilities.h | 4 + src/qemu/qemu_capabilities.c | 127 +++++++++++++++++++-- src/qemu/qemu_monitor_json.c | 31 +++-- tests/domaincapsschemadata/qemu_2.12.0.x86_64.xml | 5 +- tests/qemucapabilitiesdata/caps_2.12.0.x86_64.xml | 6 + tests/qemucapabilitiesdata/caps_3.0.0.x86_64.xml | 1 - ...args => launch-security-sev.x86_64-2.12.0.args} | 19 +-- tests/qemuxml2argvtest.c | 4 +- 8 files changed, 164 insertions(+), 33 deletions(-) rename tests/qemuxml2argvdata/{launch-security-sev.args => launch-security-sev.x86_64-2.12.0.args} (54%) -- 2.14.4
In order to test SEV we need real QEMU capabilities. Ideally, this would be tested with -latest capabilities, however, our capabilities are currently tied to Intel HW, even the 2.12.0 containing SEV were edited by hand, so we can only use that one for now, as splitting the capabilities according to the vendor is a refactor for another day. The need for real capabilities comes from the extended SEV platform data (PDH, cbitpos, etc.) we'll need to cache/parse.

Thanks, I pushed the series. Erik
Since we're not saving the platform-specific data into a cache, we're not going to populate the structure, which in turn will cause a crash upon calling virNodeGetSEVInfo because of a NULL pointer dereference. Ultimately, we should start caching this data along with host-specific capabilities like NUMA and SELinux stuff into a separate cache, but for the time being, this is a semi-proper fix for a potential crash.
