Depending on the timezone you're running CS (before GMT timezones) you could experience that some jobs are marked as failed since the parent job got a null result despite its child job having successfully done the job. The child job got deleted by the CleanupTask ahead of time, due to a missing datetime conversion to GMT timezone.
Jobs are failing with this message: Job failed with un-handled exception
The fix intends to correct any datetime used in the code that should be using the GMT timezone instead of the local one since all DB datetime should be stored at GMT.

Fix: Block VMOperations if Host in PrepareForMaintenance mode. VM operations (Stop, Reboot, Destroy, Migrate to host) are not allowed when Host in PrepareForMaintenance mode.
Host-HA offers investigation, fencing and recovery mechanisms for host that for
any reason are malfunctioning. It uses Activity and Health checks to determine
current host state based on which it may degrade a host or try to recover it. On
failing to recover it, it may try to fence the host.
The core feature is implemented in a hypervisor agnostic way, with two separate
implementations of the driver/provider for Simulator and KVM hypervisors. The
framework also allows for implementation of other hypervisor specific provider
implementation in future.
The Host-HA provider implementation for KVM hypervisor uses the out-of-band
management sub-system to issue IPMI calls to reset (recover) or poweroff (fence)
a host.
The Host-HA provider implementation for Simulator provides a means of testing
and validating the core framework implementation.

This introduces a new certificate authority framework that allows
pluggable CA provider implementations to handle certificate operations
around issuance, revocation and propagation. The framework injects
itself to `NioServer` to handle agent connections securely. The
framework adds assumptions in `NioClient` that a keystore if available
with known name `cloud.jks` will be used for SSL negotiations and
handshake.
This includes a default 'root' CA provider plugin which creates its own
self-signed root certificate authority on first run and uses it for
issuance and provisioning of certificate to CloudStack agents such as
the KVM, CPVM and SSVM agents and also for the management server for
peer clustering.
Additional changes and notes:
- Comma separate list of management server IPs can be set to the 'host'
global setting. Newly provisioned agents (KVM/CPVM/SSVM etc) will get
radomized comma separated list to which they will attempt connection
or reconnection in provided order. This removes need of a TCP LB on
port 8250 (default) of the management server(s).
- All fresh deployment will enforce two-way SSL authentication where
connecting agents will be required to present certificates issued
by the 'root' CA plugin.
- Existing environment on upgrade will continue to use one-way SSL
authentication and connecting agents will not be required to present
certificates.
- A script `keystore-setup` is responsible for initial keystore setup
and CSR generation on the agent/hosts.
- A script `keystore-cert-import` is responsible for import provided
certificate payload to the java keystore file.
- Agent security (keystore, certificates etc) are setup initially using
SSH, and later provisioning is handled via an existing agent connection
using command-answers. The supported clients and agents are limited to
CPVM, SSVM, and KVM agents, and clustered management server (peering).
- Certificate revocation does not revoke an existing agent-mgmt server
connection, however rejects a revoked certificate used during SSL
handshake.
- Older `cloudstackmanagement.keystore` is deprecated and will no longer
be used by mgmt server(s) for SSL negotiations and handshake. New
keystores will be named `cloud.jks`, any additional SSL certificates
should not be imported in it for use with tomcat etc. The `cloud.jks`
keystore is stricly used for agent-server communications.
- Management server keystore are validated and renewed on start up only,
the validity of them are same as the CA certificates.
New APIs:
- listCaProviders: lists all available CA provider plugins
- listCaCertificate: lists the CA certificate(s)
- issueCertificate: issues X509 client certificate with/without a CSR
- provisionCertificate: provisions certificate to a host
- revokeCertificate: revokes a client certificate using its serial
Global settings for the CA framework:
- ca.framework.provider.plugin: The configured CA provider plugin
- ca.framework.cert.keysize: The key size for certificate generation
- ca.framework.cert.signature.algorithm: The certificate signature algorithm
- ca.framework.cert.validity.period: Certificate validity in days
- ca.framework.cert.automatic.renewal: Certificate auto-renewal setting
- ca.framework.background.task.delay: CA background task delay/interval
- ca.framework.cert.expiry.alert.period: Days to check and alert expiring certificates
Global settings for the default 'root' CA provider:
- ca.plugin.root.private.key: (hidden/encrypted) CA private key
- ca.plugin.root.public.key: (hidden/encrypted) CA public key
- ca.plugin.root.ca.certificate: (hidden/encrypted) CA certificate
- ca.plugin.root.issuer.dn: The CA issue distinguished name
- ca.plugin.root.auth.strictness: Are clients required to present certificates
- ca.plugin.root.allow.expired.cert: Are clients with expired certificates allowed
UI changes:
- Button to download/save the CA certificates.
Misc changes:
- Upgrades bountycastle version and uses newer classes

CloudStack has several background polling tasks that are spread across
the codebase, the aim of this work is to provide a single manager to
handle submission, execution and handling of background tasks. With
the framework implemented, existing oobm background task has been

CLOUDSTACK-9669: replacing 0.0.0.0/0 with the network cidr
ipset member add with 0.0.0.0/0 fails. So 0.0.0.0/0 replaced with the network cidr.
In source cidr 0.0.0.0/0 is nothing but network cidr.
updated the default egress all cidr with network cidr
The 'force' option provided with the stopVirtualMachine API command is
often assumed to be a hard shutdown sent to the hypervisor, when in fact
it is for CloudStacks' internal use. CloudStack should be able to send
the 'hard' power-off request to the hosts.
When forced parameter on the stopVM API is true, power off (hard shutdown)
a VM. This uses initial changes from #1635 to pass the forced parameter
to hypervisor plugin via the StopCommand, and fixes force stop (poweroff)
handling for KVM, VMware and XenServer.

(1) add support to create/delete/revert vm snapshots on running vms with QCOW2 format
(2) add new API to create volume snapshot from vm snapshot
(3) delete metadata of vm snapshots before stopping/migrating and recover vm snapshots after starting/migrating
(4) enable deleting of VM snapshot on stopped vm or vm snapshot is not listed in qcow2 image.
(5) enable smoke tests for vmsnaphsots on KVM
Introduced a global configuration flag 'cluster.threshold.enabled'. By default the flag is true.
If the value is false, then a VM can be started in a cluster even if the cluster thresholds are
crossed. However, for a new VM deployment the cluster threshold will always be honoured.
Made the changes to improve logging.CLOUSTACK-9465 Several log refactoring/improvement suggestions.
There are two scenarios of logging which needs refactoring/improvement:
Method invocation replaced by variable
This means that in the logging code, the method invocation is pre-defined as a variable. for simplicity, the method invocation should be replaced by the variable.
Delete variable which must be null
The variable in the logging code is null, there is no need to put the variable there.

- Unit test to demonstrate denial of service attack
The NioConnection uses blocking handlers for various events such as connect,
accept, read, write. In case a client connects NioServer (used by
agent mgr to service agents on port 8250) but fails to participate in SSL
handshake or just sits idle, this would block the main IO/selector loop in
NioConnection. Such a client could be either malicious or aggresive.
This unit test demonstrates such a malicious client that can perform a
denial-of-service attack on NioServer that blocks it to serve any other client.
- Use non-blocking SSL handshake
- Uses non-blocking socket config in NioClient and NioServer/NioConnection
- Scalable connectivity from agents and peer clustered-management server
- Removes blocking ssl handshake code with a non-blocking code
- Protects from denial-of-service issues that can degrade mgmt server responsiveness
due to an aggressive/malicious client
- Uses separate executor services for handling ssl handshakes

This reverts commit 7ce0e10fbc, reversing
changes made to 29ba71f2db.
This was reverted because it seemed to be related to an issue
when doing a DeployDC, causing an `addHost` error.
Notify listeners when a host has been added to a cluster, is about to be removed from a cluster, or has been removed from a cluster
This PR addresses the following JIRA ticket:
https://issues.apache.org/jira/browse/CLOUDSTACK-8813
The problem is that there needs to be notifications sent when a host is added to, about to be removed from, and removed from a cluster.
Such notifications can be used for many purposes. For example, it can allow storage plug-ins to update ACLs on their storage systems. Also, it can allow us to clean up IQNs from ESXi hosts that are no longer needed.

Support access to a host’s out-of-band management interface (e.g. IPMI, iLO,
DRAC, etc.) to manage host power operations (on/off etc.) and querying current
power state in CloudStack.
Given the wide range of out-of-band management interfaces such as iLO and iDRA,
the service implementation allows for development of separate drivers as plugins.
This feature comes with a ipmitool based driver that uses the
ipmitool (http://linux.die.net/man/1/ipmitool) to communicate with any
out-of-band management interface that support IPMI 2.0.
This feature allows following common use-cases:
- Restarting stalled/failed hosts
- Powering off under-utilised hosts
- Powering on hosts for provisioning or to increase capacity
- Allowing system administrators to see the current power state of the host
For testing this feature `ipmisim` can be used:

Changes are covered the NioTest so I did not write a new test, advise how we can improve this. Further, I tried to invest time on writing a benchmark test to reproduce a degraded server but could not write it deterministic-ally (sometimes fails/passes but not always).
