[libvirt] [PATCH v2 0/9] More consistent virDomainUndefine flag handling
by Eric Blake 21 Aug '19

21 Aug '19

Since v1: - use syntax-check rather than dynamic runtime check for API mismatch - fix more stragglers with mismatched API, found by the syntax-check - fix a bug in bhyve no-op flag handling - expand no-op flag handling to other affected drivers Eric Blake (9): vbox: Add various vir*Flags API xenapi: Add various vir*Flags API maint: Enhance check-driverimpls.pl to check for API pairing bhyve: Ignore no-op flag during virDomainUndefine libxl: Ignore no-op flag during virDomainUndefine lxc: Ignore no-op flag during virDomainUndefine openvz: Ignore no-op flag during virDomainUndefine vmware: Ignore no-op flag during virDomainUndefine xenapi: Ignore no-op flag during virDomainUndefine src/bhyve/bhyve_driver.c | 6 +++++- src/check-driverimpls.pl | 33 +++++++++++++++++++++++++++++++-- src/libxl/libxl_driver.c | 4 +++- src/lxc/lxc_driver.c | 5 ++++- src/openvz/openvz_driver.c | 5 ++++- src/vbox/vbox_common.c | 24 ++++++++++++++++++++++-- src/vmware/vmware_driver.c | 5 ++++- src/xenapi/xenapi_driver.c | 28 ++++++++++++++++++++++++---- 8 files changed, 97 insertions(+), 13 deletions(-) -- 2.20.1

[libvirt] [PATCH 0/5] security: Deal with stale XATTRs
by Michal Privoznik 21 Aug '19

21 Aug '19

There are some ways users can end up in stale XATTRs. One is sudden power loss, the other is stopping libvirt whilst some domains are running and then rebooting the host. And I believe users will find other creative ways to shut down domains without qemuProcessStop() being called. When that happens our XATTRs will be left behind and not reflect the real state of things (e.g. refcounter). To resolve this, record a timestamp within XATTRs too so that host reboots can be detected.

[libvirt] [PATCH] virt-aa-helper: Drop unnecessary AppArmor rule
by Andrea Bolognani 21 Aug '19

Apparently /proc/self is automatically converted to /proc/@{pid} before checking rules, which makes spelling it out explicitly redundant.

[libvirt] [PATCH v3 0/2] snapshot: Store both config and live XML in the snapshot domain
by Maxiwell S. Garcia 21 Aug '19

This patchset store both config and live XML in the snapshot XML.
