When auth strictness is set to true, terminate SSH handshake for clients
that do not present valid certificates.
This uses the `setNeedClientAuth`, where if the option is set and the
client chooses not to provide authentication information about itself,
the negotiations will stop and the engine will begin its closure
procedure:
https://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLEngine.html#setNeedClientAuth(boolean)
During systemvm reboot, the conf folder is removed and certificate
re-setup is not done. This may cause the agent to not connect, this
fixes the case by backing up and restoring keystore and other config
files when re-patching is done after rebooting of a systemvm (cpvm, ssvm).

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
- Refactors SAMLUtil to use new CertUtils

If a public IP is assigned to a VPC, a VM running inside that VPC cannot ping that public IP. This is due to the IPtables Nat rules set in such a way that drop any requests to the public IP from internal interfaces. I am fixing this so that internal hosts can also reach the public IP.
Reproduction:
Create a VPC
Create a network inside the VPC
Allocate a public IP
Create a VM in the network
Create a port forwarding rule enabling ICMP
ping the public IP inside the VM (this will fail)
This makes sure IP address is active.
After a vRouter is recreated (e.g. reboot via CloudStack UI) and Remote Access VPN enabled, VPN won't work anymore. Here is the abbreviated output of "ipsec auto -status" while we were having the issue:
root@r-10-VM:~# ipsec auto --status
000 using kernel interface: netkey
000 interface lo/lo 127.0.0.1
000 interface lo/lo 127.0.0.1
000 interface eth0/eth0 169.254.1.45
000 interface eth0/eth0 169.254.1.45
000 %myid = (none)
After this commit, the following occurs and VPNs work:
root@r-10-VM:~# ipsec auto --status
000 using kernel interface: netkey
000 interface lo/lo 127.0.0.1
000 interface lo/lo 127.0.0.1
000 interface eth0/eth0 169.254.1.45
000 interface eth0/eth0 169.254.1.45
000 interface eth1/eth1 xxx.xxx.xxx.172
000 interface eth1/eth1 xxx.xxx.xxx.172
000 interface eth2/eth2 192.168.1.1
000 interface eth2/eth2 192.168.1.1
000 %myid = (none)
eth1 interface IP is masked, but now ipsec sees all the interfaces and VPN works.
Looks like this bug was introduced by Pull Request #1423
It added code to start ipsec (cloudstack/systemvm/patches/debian/config/opt/cloud/bin/configure.py)
if vpnconfig['create']:
logging.debug("Enabling remote access vpn on "+ public_ip)

This change removes an unnecessary conversion from IPNetwork
to list in one of the router scripts. This makes the router
faster at processing static NAT rules, which can prevent
timeouts when attaching or detaching IPs.

When enabling remote access VPN, a new interface is created upon client connecting via VPN. The DNS service (dnsmasq) is set only to listen on interfaces that are active when it starts. Thus VPN users are provided the VR's IP address for DNS resolution, but it is not actually listening for DNS requests.
Mozilla Firefox displays white tile in place of cursor. The reason - function isImageLoaded() always returns true after first load and function checkUpdate() reloads too fast.
Suggested fix - in refresh() method state imageLoaded should be reverted to false. This ensures that function checkUpdate() processes only when tile image is loaded.
Current SSL protocol and ciphers used in SystemVMs are not the
recommended. To analyze it is possible to use tests such as from SSL
Labs (https://www.ssllabs.com/ssltest/). This commit changes the grade
from C to -A
This enables the firewall/mangle tables rules to ACCEPT instead of RETURN, which
is the same behaviour as observed in ACS 4.5. By accepting the traffic, guest
VMs will be able to communicate tcp traffic between each other over snat public
IPs.

- do not keep passwords in databag (/etc/cloudstack/vmpasswd.json)
- process only the password we get in (vm_password.json) from mgt server
- lookup the correct passwd server instead of adding passwd to all of them
Example:
- 4 tiers and 199 VMs running
- Start vm 200 would cause new passwd from vm_password.json (1) to be merged with /etc/cloudstack/vmpasswd.json (199)
- A curl command was exected foreach password (200) foreach tier (4) resulting in 800 calls
- In fact, since passwds are never cleaned it could very well be even more as the ip address was the key in the json file so until the ip address was reused the original password would remain and be sent to passwd server every time another vm starts.
- This took ~40 seconds
Now we just figure out the right tier and only process the new password resulting in a single curl call.
- takes 0,03 seconds!

[CLOUDSTACK-9793] Faster IP in subnet checkThis change removes the conversion from IPNetwork to list in one of the router scripts. This makes the router faster at processing static NAT rules, which can prevent timeouts when attaching or detaching IPs.
With the `list` conversion, it has to potentially check a list of 65536 IP strings multiple times. We assume that the comparison implemented in the IPNetwork is far more efficient. We have seen speed-up from 218 seconds to enable static NAT with 18 IPs on the router to 2 or 3 seconds by removing this cast. This also fixes a potential bug where adding IPs to a router time out because the scripts are taking too long. 218 seconds, for example, is beyond the timeout on the KVM agent for script execution, and then all enableStaticNat operations will fail.

Updated StrongSwan VPN ImplementationThis PR is a merge of @jayapalu changes in #872 and the changes I had to make to get the functionality working.
I have done pretty extensive testing of this code so far and we are looking to be in pretty good shape. One thing to note is that a `Diffie-Hellman` group **is required** in order for this feature to work correctly. It is not highlighted in the tests below, but I have shown that the `PFS` is not required for this feature to work. In #872 I have shown a more exhaustive set of tests of this code, but I have limited this set of tests to a recommended `IKE` and `ESP` configuration in order to reduce the noise and test the other areas of functionality.
**Test Results**
I am testing this functionality by creating two VPCs with VMs in each and creating a S2S VPN connection between the two VPCs. Then I SSH into a VM in one VPC and I ping the private IP of a VM in the other VPC. Then I tear it down and try a different configuration.
_Setup_
```
VPC 1 VPC 2
===== =====
VPN Gateway VPN Gateway
VPN Customer Gateway VPN Customer Gateway
VPN Connection <---> VPN Connection
- Passive = True - Passive = False
```
_Legend_
`SKIP` => At least one of the VPN Connections did not come up, so no test was run.
`OK` => The ping test was successful over the S2S VPN connection.
`FAIL` => The ping test failed over the S2S VPN connection.
`Passive` => Specifies if either the `<vpc_1> : <vpc_2>` sides of the VPN Connection is set to passive.
`Conn State` => Specifies the connection status of the `<vpc_1> : <vpc_2>` VPN Connection in the UI.
`Requires Reset` => If the ping test does not result in an `OK`, then a VPN Connection Reset is performed on either `<vpc_1> : <vpc_2>` sides of the VPN Connection based on which side is not showing `Connected`. The results in the `Status` column is the final result after the reset is performed.

-fix the case where nic_device_id is empty when ip is getting disassociated
resulting in empty deviceid in ips.json
-add utility methods in CsRule, and CsRoute to add 'ip rule' and 'ip route' rules respectivley
-ensure traffic from all public interfaces are connection marked with device number, and restored
for the reverse traffic. use the connection marked number to do device specific routing table lookup
fill the device specific routing table with default route
-component tests for testing multiple public interfaces of VR

This commit adds a additional VirtIO channel with the name
'org.qemu.guest_agent.0' to all Instances.
With the Qemu Guest Agent the Hypervisor gains more control over the Instance if
these tools are present inside the Instance, for example:
* Power control
* Flushing filesystems
* Fetching Network information
In the future this should allow safer snapshots on KVM since we can instruct the
Instance to flush the filesystems prior to snapshotting the disk.
More information: http://wiki.qemu.org/Features/QAPI/GuestAgent
Keep in mind that on Ubuntu AppArmor still needs to be disabled since the default
AppArmor profile doesn't allow libvirt to write into /var/lib/libvirt/qemu
This commit does not add any communication methods through API-calls, it merely
adds the channel to the Instances and installs the Guest Agent in the SSVMs.
With the addition of the Qemu Guest Agent channel a second channel appears in /dev
on a SSVM as a VirtIO port.
The order in which the ports are defined in the XML matters for the naming inside
the SSVM VM and by not relying on /dev/vportXX but looking for a static name the
SSVM still boots properly if the order in the XML definition is changed.
A SSVM with both ports attached will have something like this:
root@v-215-VM:~# ls -l /dev/virtio-ports
total 0
lrwxrwxrwx 1 root root 11 May 13 21:41 org.qemu.guest_agent.0 -> ../vport0p2
lrwxrwxrwx 1 root root 11 May 13 21:41 v-215-VM.vport -> ../vport0p1
root@v-215-VM:~# ls -l /dev/vport*
crw------- 1 root root 251, 1 May 13 21:41 /dev/vport0p1
crw------- 1 root root 251, 2 May 13 21:41 /dev/vport0p2
root@v-215-VM:~#
In this case the SSVM port points to /dev/vport0p1, but if the order in the XML
is different it might point to /dev/vport0p2
By looking for a portname with a pre-defined pattern in /dev/virtio-ports we
do not rely on the order in the XML definition.
