Added support for PowerFlex/ScaleIO (v3.5 onwards) storage pool as a primary storage in CloudStack (for KVM hypervisor) and enabled VM/Volume operations on that pool (using pool tag).
Please find more details in the FS here:
https://cwiki.apache.org/confluence/x/cDl4CQ
Documentation PR: apache/cloudstack-documentation#169
This enables support for PowerFlex/ScaleIO (v3.5 onwards) storage pool as a primary storage in CloudStack
Other improvements addressed in addition to PowerFlex/ScaleIO support:
- Added support for config drives in host cache for KVM
=> Changed configuration "vm.configdrive.primarypool.enabled" scope from Global to Zone level
=> Introduced new zone level configuration "vm.configdrive.force.host.cache.use" (default: false) to force host cache for config drives
=> Introduced new zone level configuration "vm.configdrive.use.host.cache.on.unsupported.pool" (default: true) to use host cache for config drives when storage pool doesn't support config drive
=> Added new parameter "host.cache.location" (default: /var/cache/cloud) in KVM agent.properties for specifying the host cache path and create config drives on the "/config" directory on the host cache path
=> Maintain the config drive location and use it when required on any config drive operation (migrate, delete)
- Detect virtual size from the template URL while registering direct download qcow2 (of KVM hypervisor) templates
- Updated full deployment destination for preparing the network(s) on VM start
- Propagate the direct download certificates uploaded to the newly added KVM hosts
- Discover the template size for direct download templates using any available host from the zones specified on template registration
=> When zones are not specified while registering template, template size discovery is performed using any available host, which is picked up randomly from one of the available zones
- Release the VM resources when VM is sync-ed to Stopped state on PowerReportMissing (after graceful period)
- Retry VM deployment/start when the host cannot grant access to volume/template
- Mark never-used or downloaded templates as Destroyed on deletion, without sending any DeleteCommand
=> Do not trigger any DeleteCommand for never-used or downloaded templates as these doesn't exist and cannot be deleted from the datastore
- Check the router filesystem is writable or not, before performing health checks
=> Introduce a new test "filesystem.writable.test" to check the filesystem is writable or not
=> The router health checks keeps the config info at "/var/cache/cloud" and updates the monitor results at "/root" for health checks, both are different partitions. So, test at both the locations.
=> Added new script: "filesystem_writable_check.py" at /opt/cloud/bin/ to check the filesystem is writable or not
- Fixed NPE issue, template is null for DATA disks. Copy template to target storage for ROOT disk (with template id), skip DATA disk(s)
* Addressed some issues for few operations on PowerFlex storage pool.
- Updated migration volume operation to sync the status and wait for migration to complete.
- Updated VM Snapshot naming, for uniqueness in ScaleIO volume name when more than one volume exists in the VM.
- Added sync lock while spooling managed storage template before volume creation from the template (non-direct download).
- Updated resize volume error message string.
- Blocked the below operations on PowerFlex storage pool:
-> Extract Volume
-> Create Snapshot for VMSnapshot
* Added the PowerFlex/ScaleIO client connection pool to manage the ScaleIO gateway clients, which uses a single gateway client per Powerflex/ScaleIO storage pool and renews it when the session token expires.
- The token is valid for 8 hours from the time it was created, unless there has been no activity for 10 minutes.

Other fixes included:
- Fail the VM deployment when the host specified in the deployVirtualMachine cmd is not in the right state (i.e. either Resource State is not Enabled or Status is not Up)
- Use the physical file size of the template to check the free space availability on the host, while downloading the direct download templates.
- Perform basic tests (for connectivity and file system) on router before updating the health check config data
=> Validate the basic tests (connectivity and file system check) on router
=> Cleanup the health check results when router is destroyed
* Updated PowerFlex/ScaleIO storage plugin version to 4.16.0.0
* UI Changes to support storage plugin for PowerFlex/ScaleIO storage pool.
- PowerFlex pool URL generated from the UI inputs(Gateway, Username, Password, Storage Pool) when adding "PowerFlex" Primary Storage
- Updated protocol to "custom" for PowerFlex provider
- Allow VM Snapshot for stopped VM on KVM hypervisor and PowerFlex/ScaleIO storage pool
and Minor improvements in PowerFlex/ScaleIO storage plugin code
* Added support for PowerFlex/ScaleIO volume migration across different PowerFlex storage instances.
- findStoragePoolsForMigration API returns PowerFlex pool(s) of different instance as suitable pool(s), for volume(s) on PowerFlex storage pool.
- Volume(s) with snapshots are not allowed to migrate to different PowerFlex instance.
- Volume(s) of running VM are not allowed to migrate to other PowerFlex storage pools.
- Volume migration from PowerFlex pool to Non-PowerFlex pool, and vice versa are not supported.
* Fixed change service offering smoke tests in test_service_offerings.py, test_vm_snapshots.py
* Added the PowerFlex/ScaleIO volume/snapshot name to the paths of respective CloudStack resources (Templates, Volumes, Snapshots and VM Snapshots)
* Added new response parameter “supportsStorageSnapshot” (true/false) to volume response, and Updated UI to hide the async backup option while taking snapshot for volume(s) with storage snapshot support.
* Fix to remove the duplicate zone wide pools listed while finding storage pools for migration
* Updated PowerFlex/ScaleIO volume migration checks and rollback migration on failure
* Fixed the PowerFlex/ScaleIO volume name inconsistency issue in the volume path after migration, due to rename failure
Steps to reproduce the issue
(1) create two vm wei-001 and wei-002, start them
(2) check /etc/cloudstack/dhcpentry.json and /etc/dhcphosts.txt in VR
They have entries for both of wei-001 and wei-002
(3) stop wei-002, and restart VR (or restart network with cleanup).
check /etc/cloudstack/dhcpentry.json and /etc/dhcphosts.txt in VR
They have entries for wei-001 only (as wei-002 is stopped)
(4) expunge wei-002. when it is done,
check /etc/cloudstack/dhcpentry.json and /etc/dhcphosts.txt in VR
They do not have entries for wei-001.
VR health check fails at dhcp_check.py and dns_check.py

The previous setup of many hours would not work, due to some internal dnsmasq issues - lease was set correclty, but dnsmasq was setting the dhcp-renew-time (and rebind time) to less than 2 years from the date the lease was issued.
Using "infinite" as the value (instead of the number) works as expected - and (atm) the renew date is set to year 2088, etc.

```
We need to change the pid file from /var/run/haproxy.pid to /run/haproxy.pid, so the haproxy will be reloaded instead of restarted.
When we create a vm in the network with redundant VRs, the lease file in the vm (for example /var/lib/dhcp/dhclient.eth0.leases) shows the dhcp-server-identifier is the guest ip (not vip/gateway) of master VR. That's the ip ipaddress where the vm fetch password and metadata from.
if we stop the master VR (then backup will be master) or restart the network with cleanup (VRs will be created), the guest ip of master VR changes so vm are not able to get metadata/ssh-key using the ips in dhcp lease file.
Setting up metadata/password/dhcp server on gateway instead of guest IP in redundant VRs will fix the issues.

This does not remove VM entries in dbags when hostnames match. The

we don't need to handle lazy removal. This will allow a VM on

The VR code has provision for inserting rules at the top or bottom by specifying "front" as the second parameter to self.fw.append. However, there are a number of cases where someone has been unaware of this and added a rule with the pattern self.fw.append(["mangle", "", "-I PREROUTING".... This causes the code to check for the rule already being present to fail, and duplicate rules end up being added.
This PR fixes two of these cases which apply to adding static NAT rules. I am aware of more of these cases, but I don't have the ability to easily test the outcome of fixing them. I'm happy to add these in if you're confident that the automated tests will be sufficient. Searching for "-I (case sensitive) finds these.
The code for dealing with "front" is included below to show that this shouldn't have any ill effects:
if fw[1] == "front":
cpy = cpy.replace('-A', '-I')

Since the CloudStack virtual router was redesigned on version 4.6 it has been observed that the DHCP leases file is not persistent across network operations. This causes conflicts on guest VMs static IPs, causing these static IPs to not be renewed by the DHCP server running on isolated and VPC networks' virtual routers (dnsmasq). On stopping or destroying a VM, its dhcp/dns records are not removed from the virtual router causing ghost effects.

This PR resolves 2 issues related to Virtual Routers with multiple public interfaces, and works around a third.
- Fixes#3353 - Adds missing throw routes for eth0/eth1 to eth3+ when there are >1 public IPs
- Fixes#3168 - Incorrect marks set on some static NAT rules (some code references were changed from hex(int(interfacenum)) to hex(100 + int(interfacenum)) - this change just adds the remaining ones
- Fixes#3352 - Work around that sends Gratuitous ARP messages when a HA VR becomes master to work around the problem of the MAC address being different between HA VRs. If that issue is fixed properly (i.e. a database entry for the subsequent interfaces so they can be static) then this is unnecessary, though should not cause any problems.
On first startup, the management server creates and saves a random
ssh keypair using ssh-keygen in the database. The command does
not specify keys in PEM format which is not the default as generated
by latest ssh-keygen tool.
The systemvmtemplate always needs re-building whenever there is a change
in the cloud-early-config file. This also tries to fix that by introducing a
stage 2 bootstrap.sh where the changes specific to hypervisor detection
etc are refactored/moved. The initial cloud-early-config only patches
before the other scripts are called.

Previously, the ethernet device index was used as rt_table index and
packet marking id/integer. With eth0 that is sometimes used as link-local
interface, the rt_table index `0` would fail as `0` is already defined
as a catchall (unspecified). The fwmarking on packets on eth0 with 0x0
would also fail. This fixes the routing issues, by adding 100 to the
ethernet device index so the value is a non-zero, for example then the
relationship between rt_table index and ethernet would be like:
100 -> Table_eth0 -> eth0 -> fwmark 100 or 0x64
101 -> Table_eth1 -> eth1 -> fwmark 101 or 0x65
102 -> Table_eth2 -> eth2 -> fwmark 102 or 0x66
This would maintain the legacy design of routing based on packet mark
and appropriate routing table rules per table/ids. This also fixes a
minor NPE issue around listing of snapshots.
This also backports fixes to smoketests from master.

This is a new feature for CS that allows Admin users improved
troubleshooting of network issues in CloudStack hosted networks.
Description: For troubleshooting purposes, CloudStack administrators may wish to execute network utility commands remotely on system VMs, or request system VMs to ping/traceroute/arping to specific addresses over specific interfaces. An API command to provide such functionalities is being developed without altering any existing APIs. The targeted system VMs for this feature are the Virtual Router (VR), Secondary Storage VM (SSVM) and the Console Proxy VM (CPVM).

Using Source NAT option on Private Gateway does not work
This fixes#2680
## Description
<!--- Describe your changes in detail -->
When you use the Source NAT feature of Private Gateways on a VPC. This should Source NAT all traffic from CloudStack VMs going towards IPs reachable through Private Gateways.
This change in this PR, stops adding the Source CIDR to SNAT rules. This should be discussed/reviewed, but i can see no reason why the Source CIDR is needed. There can only be one SNAT IP per interface, except for Static (one-to-one) NATs, which still work with this change in place. The outbound interface is what matters in the rule.
<!-- For new features, provide link to FS, dev ML discussion etc. -->
<!-- In case of bug fix, the expected and actual behaviours, steps to reproduce. -->
##### SUMMARY
<!-- Explain the problem/feature briefly -->
There is a bug in the Private Gateway functionality, when Source NAT is enabled for the Private Gateway. When the SNAT is added to iptables, it has the source CIDR of the private gateway subnet. Since no VMs live in that private gateway subnet, the SNAT doesn’t work.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
Below is an example:
- VMs have IP addresses in the 10.0.0.0/24 subnet.
- The Private Gateway address is 10.101.141.2/30
In the outputs below, the SOURCE field for the new SNAT (eth3) only matches if the source is 10.101.141.0/30. Since the VM has an IP address in 10.0.0.0/24, the VMs don’t get SNAT’d as they should when talking across the private gateway. The SOURCE should be set to ANYWHERE.
##### BEFORE ADDING PRIVATE GATEWAY
~~~
Chain POSTROUTING (policy ACCEPT 1 packets, 52 bytes)
pkts bytes target prot opt in out source destination
2 736 SNAT all -- any eth2 10.0.0.0/24 anywhere to:10.0.0.1
16 1039 SNAT all -- any eth1 anywhere anywhere to:46.99.52.18
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
Chain POSTROUTING (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
0 0 SNAT all -- any eth3 anywhere anywhere to:10.101.141.2
2 736 SNAT all -- any eth2 anywhere anywhere to:10.0.0.1
23 1515 SNAT all -- any eth1 anywhere anywhere to:46.99.52.18

This ensures that password server runs on the dhcpserver identifier
IP which is the not the VRRP virtual (10.1.1.1) IP by default but
the actual ip of the interface. When dhcp client discovery is made,
the `dhcp-server-identifier` contains the non VIP address that is
used by password reset script to query guest VM password.

This fixes incorrect xenstore-read binary path, this failed systemvm

This might (and does block) in certain situations on the VR as
also explained in the Python documentation:
https://docs.python.org/2/library/subprocess.html#subprocess.Popen.wait
Warning This will deadlock when using stdout=PIPE and/or stderr=PIPE
and the child process generates enough output to a pipe such that
it blocks waiting for the OS pipe buffer to accept more data.
Use communicate() to avoid that.
Using the check_output function handles most of this for us and
also provides better error handling.

Under Debian 7 the 'file' command would return:

Under Debian 9 however it will return
debian-9.1.0-amd64-netinst.iso: DOS/MBR boot sector
This would make the HTTPTemplateDownloader in the Secondary Storage VM refuse the ISO as
a valid template because it's not a correct format.
Changes this behavior so that it accepts both.
This allows us to use Debian 9 as a System VM template.
Not sure though if enabling them is enough for systemd to still start them

We found bug in ACL rules for PrivateGateway for VPC
At a glance - rules not applied - switching Allow All or Deny All (default ACL) - showed as completed - but rules missed.
Result - traffic via PrivateGateway blocked by next DROP rule in next chains
How to reproduce:
Enable PrivateGateway for Cloudstack
Create VPC
Provision new PrivateGateway inside VPC with some VLAN
Change ACL (optional step to show that problem not in initial configuration but in config itself)
Expected:
ACL rules applied (inserted) into correspondig ACL_INBOUND/OUTBOUND chanins for PrivateGateway interface (ethX) based on ACL which user choose
Current:
No rules inserted. ACL_INBOUND/OUTBOUND_ethX - empty. Traffic blocked by next DROP rule in FORWARD chain
Affect - all our corporate customers blocked with access to their own nets via PG and vice-versa.
Root cause:
Issue happened because of CsNetFilter.py logic for inserting rules for ACL_INBOUND/OUTBOUND chains.
We choose rule numebr to isnert right before last DROP rule - but forget about fact - that if chain empty - we also return 0 as insert position. Which not true for iptables - numeration started from 0.
So we need very small patch to handle this special case - if number of rules inside chain equal to zero - return 1, else - return count of rules inside chain.
It's found only one - just because be default for PrivateGateway - we didn't insert any "service rules" (if SourceNat for PrivateGteway not ticked) - and we have by default empty ACL_INBOUND/OUTBOUND chains. Because same insert happened for all VPC networks (but when we call this insert - we already have at least 1 rule inside chains - and we successfully can process)
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:

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)
CsHelper.start_if_stopped("ipsec")
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.
