Plans for the next release
by Jiri Denemark
We are getting close to the last release of libvirt in 2020. To aim for
the release on Dec 01 I suggest entering the freeze on Wednesday Nov 25
and tagging RC2 on Friday Nov 27.
I hope this works for everyone.

[PATCH v2] selinux label: restore all labels when some labels fail to set
by Jin Yan
When migration fails, qemuMigrationDstPrepareAny will call qemuProcessStop
to restore labels only after all labels are successfully set. If some labels
fail to set, the labels that have been set will not be restored.

[PATCH] apparmor: allow kvm-spice compat wrapper
by Christian Ehrhardt
'kvm-spice' is a binary name used to call 'kvm' which actually is a wrapper
around qemu-system-x86_64 enabling kvm acceleration. This isn't in use
for quite a while anymore, but required to work for compatibility e.g.
when migrating in old guests.
For years this was a symlink kvm-spice->kvm and therefore covered
apparmor-wise by the existing entry:
/usr/bin/kvm rmix,
But due to a recent change [1] in qemu packaging this now is no symlink,
but a wrapper on its own and therefore needs an own entry that allows it
to be executed.

[libvirt PATCH] sockettest: testMaskNetwork: use g_auto
by Ján Tomko
This has the added benefit of 'gotnet' only being freed after
it was possibly used in the output string.

[libvirt PATCH 00/10] add support for ESP SCSI controller family
by Daniel P. Berrangé
The sparc machines types all have an NCR53C90 SCSI Controller
builtin. This is from the ESP family of SCSI controllers which
includs two PCI variants. Wire up support for all these SCSI
controllers, so we can at least launch a sparc VM with disks
attached. There are likely other gaps in CLI coverage for sparc,
so I don't claim this lets you have a fully working VM yet.
Daniel P. Berrangé (10):
util: add ARCH_IS_MIPS64 helper macro
qemu: fix default devices on sparc machines
qemu: add helper method for checking if ESP SCSI is builtin
conf: add support for ESP SCSI controller family
qemu: add capabilities for the three ESP family SCSI controllers
qemu: enable support for ESP SCSI controller family
tests: add fake host CPU for sparc architecture
tests: add capabilities data files for sparc emulator target
tests: define QEMU driver capabilities for sparc architecture
tests: add minimal XML example for sparc VM

[PATCH] domain_capabilities: Assert enums fit into unsigned int bitmask
by Michal Privoznik
The way our domain capabilities work currently, is that we have
virDomainCapsEnum struct which contains 'unsigned int values'
member which serves as a bitmask. More complicated structs are
composed from this struct, giving us whole virDomainCaps
eventually.
Whenever we want to report that a certain value is supported, the
'1 << value' bit is set in the corresponding unsigned int member.
This works as long as the resulting value after bitshift does not
overflow unsigned int. There is a check inside
virDomainCapsEnumSet() which ensures exactly this, but no caller
really checks whether virDomainCapsEnumSet() succeeded. Also,
checking at runtime is a bit too late.
Fortunately, we know the largest value we want to store in each
member, because each enum of ours ends with _LAST member.
Therefore, we can check at build time whether an overflow can
occur.
