CLOUDSTACK-9359: IPv6 for Basic NetworkingThis PR is a proposal for adding very basic IPv6 to Basic Networking. The main goal of this PR is that the API returns a valid IPv6 address over which the Instance is reachable.
The GUI will show the IPv6 address after deployment of the Instance.
If the table VLAN has a proper IPv6 CIDR configured the DirectPodBasedNetworkGuru will calculate the IPv6 Address the Instance will obtain using EUI-64 and SLAAC: https://tools.ietf.org/search/rfc4862
In this case the _vlan_ table contained:
<pre>mysql> select * from vlan \G

It will then log:

The template has to be configured accordingly:
- No IPv6 Privacy Extensions
- Use SLAAC
- Follow RFC4862
This is also described in: https://cwiki.apache.org/confluence/display/CLOUDSTACK/IPv6+in+Basic+Networking
The next steps after this will be:
- Security Grouping to prevent IPv6 Address Spoofing
- Security Grouping to filter ICMP, UDP and TCP traffic

CLOUDSTACK-9619: Updates for SAN-assisted snapshotsThis PR is to address a few issues in #1600 (which was recently merged to master for 4.10).
In StorageSystemDataMotionStrategy.performCopyOfVdi we call getSnapshotDetails. In one such scenario, the source snapshot in question is coming from secondary storage (when we are creating a new volume on managed storage from a snapshot of ours thats on secondary storage).
This usually worked in the regression tests due to a bit of "luck": We retrieve the ID of the snapshot (which is on secondary storage) and then try to pull out its StorageVO object (which is for primary storage). If you happen to have a primary storage that matches the ID (which is the ID of a secondary storage), then getSnapshotDetails populates its Map<String, String> with inapplicable data (that is later ignored) and you dont easily see a problem. However, if you dont have a primary storage that matches that ID (which I didnt today because I had removed that primary storage), then a NullPointerException is thrown.
I have fixed that issue by skipping getSnapshotDetails if the source is coming from secondary storage.
While fixing that, I noticed a couple more problems:
1) We can invoke grantAccess on a snapshot thats actually on secondary storage (this doesnt amount to much because the VolumeServiceImpl ignores the call when its not for a primary-storage driver).
2) We can invoke revokeAccess on a snapshot thats actually on secondary storage (this doesnt amount to much because the VolumeServiceImpl ignores the call when its not for a primary-storage driver).
I have corrected those issues, as well.
I then came across one more problem:
When using a SAN snapshot and copying it to secondary storage or creating a new managed-storage volume from a snapshot of ours on secondary storage, we attach to the SR in the XenServer code, but detach from it in the StorageSystemDataMotionStrategy code (by sending a message to the XenServer code to perform an SR detach). Since we know to detach from the SR after the copy is done, we should detach from the SR in the XenServer code (without that code having to be explicitly called from outside of the XenServer logic).
I went ahead and changed that, as well.

This commit implements Ingress and Egress filtering for IPv6 in
Basic Networking.
It allows for opening and closing ports just as can be done with IPv4.
Rules have to be specified twice, once for IPv4 and once for IPv6, for
example:
- 22 until 22: 0.0.0.0/0
- 22 until 22: ::/0
Egress filtering works the same as with IPv4. When no rule is applied all
traffic is allowed. Otherwise only the specified traffic (with DNS being
the exception) is allowed.

This commit implements basic Security Grouping for KVM in
Basic Networking.
It does not implement full Security Grouping yet, but it does:
- Prevent IP-Address source spoofing
- Allow DHCPv6 clients, but disallow DHCPv6 servers
- Disallow Instances to send out Router Advertisements
The Security Grouping allows ICMPv6 packets as described by RFC4890
as they are essential for IPv6 connectivity.
Following RFC4890 it allows:
- Router Solicitations
- Router Advertisements (incoming only)
- Neighbor Advertisements
- Neighbor Solicitations
- Packet Too Big
- Time Exceeded
- Destination Unreachable
- Parameter Problem
- Echo Request
ICMPv6 is a essential part of IPv6, without it connectivity will break or be very
unreliable.
For now it allows any UDP and TCP packet to be send in to the Instance which
effectively opens up the firewall completely.
Future commits will implement Security Grouping further which allows controlling UDP and TCP
ports for IPv6 like can be done with IPv4.
Regardless of the egress filtering (which can't be done yet) it will always allow outbound DNS
to port 53 over UDP or TCP.

This commit adds the initial functionality for IPv6 in Basic Networking.
When a valid IPv6 CIDR is configured for the POD/VLAN the DirectPodBasedNetworkGuru
will use the EUI-64 calculation to calculate the IPv6 Address the Instance will obtain.
For this it is required that the physical routers in the Layer 2 network (POD/VLAN) send out
Router Advertisements with the same subnet as configured in CloudStack.
A example subnet could be 2001:db8::/64
Using radvd a Linux Router could send out Router Advertisements using this configuration:
interface eth0
{
MinRtrAdvInterval 5;
MaxRtrAdvInterval 60;
AdvSendAdvert on;
AdvOtherConfigFlag off;
IgnoreIfMissing off;
prefix 2001:db8::/64 {
};
RDNSS 2001:db8:ffff::53 {
};
};
A Instance with MAC Address 06:7a:88:00:00:8b will obtain IPv6 address 2001:db8:100::47a:88ff:fe00:8b
Both Windows, Linux and FreeBSD use the same calculation for their IPv6 Addresses, this is specified
in RFC4862 (IPv6 Stateless Address Autoconfiguration).
Under Linux it is mandatory that IPv6 Privacy Extensions are disabled:
$ sysctl -w net.ipv6.conf.all.use_tempaddr=0
Windows should be configured to use the MAC Address as the identifier for the EUI-64/SLAAC calculation.
$ netsh interface ipv6 set privacy state=disabled store=persistent
$ netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent
The IPv6 address is stored in the 'nics' table and is then returned by the API and will be shown in the UI.
Searching for a conflicting IPv6 Address it NOT required as each IPv6 address is based on the MAC Address
of the Instance and therefor unique.
Security Grouping has not been implemented yet and will follow in a upcoming commit.

Due to OS/hypervisor/environmental configuration, detaching a disk/device
using libvirt can be successful without updating the domain configuration (xml).
This leads to reattachment failure as the device is blocked until the next
reboot. This fixes a specific environment case by performing stop/start on
the VM only in case of KVM, which will recreate a fresh domain config (xml)
as KVM VMs have transient domain configs (xmls don't persist).

Issue
====
Start instance fails after reverting to a VM snapshot, when there is 1 or more child VM snapshots in the snapshot tree of the VM.
Per the code, the method hasSnapshot() is supposed to detect the presence of any snapshot for the VM. But we are checking for only current snapshot instead of checking presence of any snapshot in the snapshot tree.
The failure to detect all snapshots means ACP reconfigures the VM in wrong way assuming there are no snapshots for the VM.
This results in start failure.

CLOUDSTACK-9639: Unable to create shared network with vLan isolationDescription:
=========
Create shared network fails with Error.
While creating a shared network it fails to create with Error "The new IP range you have specified has overlapped with the guest network in the zone: XYZ. Please specify a different gateway/netmask"
Steps to Reproduce:
===============
1. Create an isolated network with a subnet eg: 10.1.1.0/24
2. Create a shared network with the same subnet but different VLAN, we should observe this issue.
Expected Behaviour:
===============
It shouldn't restrict the creation of the guest network with the same subnet as long as they are segmented by VLAN.
ACTUAL BEHAVIOR:
===============
It doesn't allow the creation of shared guest networks if there is any isolated guest network using the same subnet although it allows using the same subnet in multiple shared networks.
Cause:
=====
The issue is happening because, when Shared network is getting created we are checking if there is any guest network already implemented with the same CIDR and throwing the error without checking if they are having same VLAN also. Creating the same CIDR shared network with different VLAN should be allowed.
Fix:
===
When creating a shared network, if there is any existing guest network with the same CIDR, we check if they are having the same VLAN, if they are in same VLAN, then we don't allow creating it. If they are in the same CIDR with different VLAN then we allowing to create the network.
