+Subject: [PATCH] Fix padding of encrypted data
+
+If we are encoding a block of data that is 16 bytes in length,
+we cannot leave it as 16 bytes, we must pad it out to the next
+block boundary, 32 bytes. Without this padding, the decoder will
+incorrectly treat the last byte of plain text as the padding
+length, as it can't distinguish padded from non-padded data.
+
+The problem exhibited itself when using a 16 byte passphrase
+for a LUKS volume
+
+  $ virsh secret-set-value 55806c7d-8e93-456f-829b-607d8c198367 \
+       $(echo -n 1234567812345678 | base64)
+  Secret value set
+
+  $ virsh start demo
+  error: Failed to start domain demo
+  error: internal error: process exited while connecting to monitor: >>>>>>>>>>Len 16

0003-Avoid-hidden-cgroup-mount-points.patch

+From: Juan Hernandez <jhernand@redhat.com>

+Subject: [PATCH] Avoid hidden cgroup mount points
+
+Currently the scan of the /proc/mounts file used to find cgroup mount
+points doesn't take into account that mount points may hidden by other
+mount points. For, example in certain Kubernetes environments the
+/proc/mounts contains the following lines:
+
+  cgroup /sys/fs/cgroup/net_prio,net_cls cgroup ...
+  tmpfs /sys/fs/cgroup tmpfs ...
+  cgroup /sys/fs/cgroup/net_cls,net_prio cgroup ...
+
+In this particular environment the first mount point is hidden by the
+second one. The correct mount point is the third one, but libvirt will
+never process it because it only checks the first mount point for each
+controller (net_cls in this case). So libvirt will try to use the first
+mount point, which doesn't actually exist, and the complete detection
+process will fail.
+
+To avoid that issue this patch changes the virCgroupDetectMountsFromFile
+function so that when there are duplicates it takes the information from
+the last line in /proc/mounts. This requires removing the previous
+explicit condition to skip duplicates, and adding code to free the
+memory used by the processing of duplicated lines.

+IRC that the attribute is "optional for input, recommended (but
+not required) for output". Currently the schema requires the

+# virt-xml-validate test.xml
+Relax-NG validity error : Extra element devices in interleave
+test.xml:21: element devices: Relax-NG validity error : Element domain failed to validate content
+test.xml fails to validate
+
+Relaxing the name attribute to be optional fixes the validation

-
-When the session dies or when the system is going to be shut down
-we save all active VMs and exit libvirtd.
-
-Additionally whenever there is an active domain we hold a
-shutdown inhibitor to avoid shutting down before all the
-VMs are saved.
