[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
