Unify checksum API output for templates and ISOs: not list the checksum algorithm on:
KVM direct downloads
On in progress normal template downloads. The algorithm is shown on the listtemplates API, but after it is downloaded it is not shown anymore.
This fixes#2719 where private gateway IP might be incorrectly
programmed on a guest network nic. The VR would now check ipassoc
requests by mac addresses than provided nic/device id in case they are
wrong.
The root cause is that the device id information is lost when aggregated
commands are created upon starting of a new VPC VR, without the correct
device id in ip_associations json it mis-programs the VR.

ACS is accounting the resources properly when deploying VMs with custom service offerings. However, there are other methods (such as updateResourceCount) that do not execute the resource accounting properly, and these methods update the resource count for an account in the database. Therefore, if a user deploys VMs with custom service offerings, and later this user calls the “updateResourceCount” method, it (the method) will only account for VMs with normal service offerings, and update this as the number of resources used by the account. This will result in a smaller number of resources to be accounted for the given account than the real used value. The problem becomes worse because if the user starts to delete these VMs, it is possible to reach negative values of resources allocated (breaking all of the resource limiting for accounts). This is a very serious attack vector for public cloud providers!

The new CA framework introduced basic support for comma-separated
list of management servers for agent, which makes an external LB
unnecessary.
This extends that feature to implement LB sorting algorithms that
sorts the management server list before they are sent to the agents.
This adds a central intelligence in the management server and adds
additional enhancements to Agent class to be algorithm aware and
have a background mechanism to check/fallback to preferred management
server (assumed as the first in the list). This is support for any
indirect agent such as the KVM, CPVM and SSVM agent, and would
provide support for management server host migration during upgrade
(when instead of in-place, new hosts are used to setup new mgmt server).
This FR introduces two new global settings:
- `indirect.agent.lb.algorithm`: The algorithm for the indirect agent LB.
- `indirect.agent.lb.check.interval`: The preferred host check interval
for the agent's background task that checks and switches to agent's
preferred host.
The indirect.agent.lb.algorithm supports following algorithm options:
- static: use the list as provided.
- roundrobin: evenly spreads hosts across management servers based on
host's id.
- shuffle: (pseudo) randomly sorts the list (not recommended for production).
Any changes to the global settings - `indirect.agent.lb.algorithm` and
`host` does not require restarting of the mangement server(s) and the
agents. A message bus based system dynamically reacts to change in these
global settings and propagates them to all connected agents.
Comma-separated management server list is propagated to agents on
following cases:
- Addition of a host (including ssvm, cpvm systevms).
- Connection or reconnection by the agents to a management server.
- After admin changes the 'host' and/or the
'indirect.agent.lb.algorithm' global settings.
On the agent side, the 'host' setting is saved in its properties file as:
`host=<comma separated addresses>@<algorithm name>`.
First the agent connects to the management server and sends its current
management server list, which is compared by the management server and
in case of failure a new/update list is sent for the agent to persist.
From the agent's perspective, the first address in the propagated list
will be considered the preferred host. A new background task can be
activated by configuring the `indirect.agent.lb.check.interval` which is
a cluster level global setting from CloudStack and admins can also
override this by configuring the 'host.lb.check.interval' in the
`agent.properties` file.
Every time agent gets a ms-host list and the algorithm, the host specific
background check interval is also sent and it dynamically reconfigures
the background task without need to restart agents.
Note: The 'static' and 'roundrobin' algorithms, strictly checks for the
order as expected by them, however, the 'shuffle' algorithm just checks
for content and not the order of the comma separate ms host addresses.

CloudStack volumes and templates are one single virtual disk in case of XenServer/XCP and KVM hypervisors since the files used for templates and volumes are virtual disks (VHD, QCOW2). However, VMware volumes and templates are in OVA format, which are archives that can contain a complete VM including multiple VMDKs and other files such as ISOs. And currently, Cloudstack only supports Template creation based on OVA files containing a single disk. If a user creates a template from a OVA file containing more than 1 disk and launches an instance using this template, only the first disk is attached to the new instance and other disks are ignored.
Similarly with uploaded volumes, attaching an uploaded volume that contains multiple disks to a VM will result in only one VMDK to being attached to the VM.
FS: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Support+OVA+files+containing+multiple+disks
This behavior needs to be improved in VMWare to support OVA files with multiple disks for both uploaded volumes and templates. i.e. If a user creates a template from a OVA file containing more than 1 disk and launches an instance using this template, the first disk should be attached to the new instance as the ROOT disk and volumes should be created based on other VMDK disks in the OVA file and should be attached to the instance.

This commit cleans up code, renames a few methods and constants.
The global/account setting 'api.allowed.source.cidr.list' is set
to 0.0.0.0/0,::/0 by default preserve the current behavior and thus
allow API calls for accounts from all IPv4 and IPv6 subnets.
Users can set it to a comma-separated list of IPv4/IPv6 subnets to
restrict API calls for Admin accounts to certain parts of their network(s).
This is to improve Security. Should an attacker steal the Access/Secret key
of an account he/she still needs to be in a subnet from where accounts are
allowed to perform API calls.
This is a good security measure for APIs which are connected to the public internet.

- Deployed network will have security policies from the network offering

- Global settings as fallback when security policies are not defined for a network
offering
- Default promiscuous mode security policy set to REJECT as it's the default

Portgroup vlan-trunking options for dvswitch: This allows admins to define
a network with comma separated vlan id and vlan
range such as vlan://200-400,21,30-50 and use the provided vlan range to
configure vlan-trunking for a portgroup in dvswitch based environment.
VLAN overlap checks are performed for:
- isolated network against existing shared and isolated networks
- dedicated vlan ranges for the physical/public network for the zone
- shared network against existing isolated network
Allow shared networks to bypass vlan overlap checks: This allows admins
to create shared networks with a `bypassvlanoverlapcheck` API flag
which when set to 'true' will create a shared network without
performing vlan overlap checks against isolated network and against
the vlans allocated to the datacenter's physical network (vlan ranges).
Notes:
- No vlan-range overlap checks are performed when creating shared networks
- Multiple vlan id/ranges should include the vlan:// scheme prefix

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

- 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

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 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.

Often, patch and security releases do not require schema migrations or
data migrations. However, if an empty upgrade class and associated
scripts are not defined, the upgrade process will break. With this
change, if a release does not have an upgrade, a noop DbUpgrade is added
to the upgrade path. This approach allows the upgrade to proceed and
for the database to properly reflect the installed version. This change
should make the release process simpler as RMs no longer need to
rememeber to create this boilerplate code when starting a new release.
Beginning with the 4.8.2.0 and 4.9.1.0 releases, the project will
formally adopt a four (4) position release number to properly accomodate
rekeases that contain only CVE fixes. The DatabaseUpgradeChecker and
Version classes made assumptions that they would always parse and
compare three (3) position version numbers. This change adds the
CloudStackVersion value object that supports both three (3) and four (4)
version numbers. It encapsulates version comparsion logic, as well as,
the rules to allow three (3) and four (4) to interoperate.
* Modifies DatabaseUpgradeChecker to handle derive an upgrade path for
a version that was not explicitly specified. It determines the
releases the first release before it with database migrations and uses
that list as the basis for the list for version being calculated. A
noop upgrade is then added to the list which causes no schema changes
or data migrations, but will update the database to the version.
* Adds unit tests for the upgrade path calculation logic in
DatabaseUpgradeChecker
* Removes dummy upgrade logic for the 4.8.2.0 introduced in previous
versions of this patch
* Introduces the CloudStackVersion value object which parses and
compares three (3) and four (4) position version numbers. This class
is intended to replace com.cloud.maint.Version.
* Adds the junit-dataprovider dependency -- allowing test data to be
concisely generated separately from the execution of a test case.

- 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

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:

- Reduces SSL handshake timeout to 15s, previously this was only 10s in
commit debfcdef78
- Adds an aggresive explicit wakeup to save the Nio main IO loop/handler from
getting blocked
- Fix NioTest to fail/succeed in about 60s, previously this was 300s
- Due to aggresive wakeup usage, NioTest should complete in less than 5s on most
systems. On virtualized environment this may slightly increase due to thread,
CPU burst/scheduling delays.

CLOUDSTACK-9348: Use non-blocking SSL handshake in NioConnection/Link- 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 connect/accept events
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). Review, CI testing and feedback requested /cc @swill @jburwell @DaanHoogland @wido @remibergsma @rafaelweingartner @GabrielBrascher

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.

CLOUDSTACK-9352: Test fails in Widows as the file separator "/" is different from "\"**Problem:**
File separator in windows ("\") is different from the expected in the test ("/"); thus, the test *com.cloud.utils.SwiftUtilTest.testSplitSwiftPath()* will fail in Windows systems.
The problem is that the input of the test is "*container/object*" but the tested method uses the *File.separator* (that depends from the OS), in windows systems the tested method (*com.cloud.utils.SwiftUtil.splitSwiftPath(String)*) looks for a "\", as the string does not contain "\" it returns an empty string and consequently results in a test failure.
**Solution:**
Create a string `String input = "container" + File.separator + "object";`, with that the test will validate the tested method verifying if the method splits the string around matches of the given regular expression (in this case *File.separator*).

CLOUDSTACK-8611:Handle SSH if server "forget" to send exit statusContinuing the work started by @likitha, I did not cherry-picked the
commit (b9181c689e) from PR <https://github.com/apache/cloudstack/pull/561> due to the fact that the path of that SshHelper class was different of the current SshHelper; that is because the fact that by cherry-picking it would seem that I had changed all the class as the code is from another file.
I made some changes from the cherry-picked commit adding @wilderrodrigues suggestions (create simple methods to have reusable code, make unit tests and create the `WAITING_OPEN_SSH_SESSION` variable to manipulate with the delay of 1000 milliseconds).
Also, I tried to simplify the logic by assuming that ....
if ((conditions & ChannelCondition.EXIT_STATUS) != 0) {
if ((conditions & (ChannelCondition.STDOUT_DATA | ChannelCondition.STDERR_DATA)) == 0) {
break;
}
}
... is the same as `((conditions & ChannelCondition.EXIT_STATUS) != 0) && ((conditions & (ChannelCondition.STDOUT_DATA | ChannelCondition.STDERR_DATA)) == 0)`. This expression has the following results according to each possible condition.
|Condition|Value|result
|-----------------|-------|------|
TIMEOUT | 0000001|false
CLOSED | 0000010 |false
STDERR_DATA | 0000100 | false
STDERR_DATA | 0001000 | false
EOF | 0010000 | false
EXIT_STATUS | 0100000 | **true**
EXIT_SIGNAL | 1000000 | false
After testing all the possibilities we can note that the condition of `(conditions & ChannelCondition.EXIT_STATUS) != 0` is sufficient; thus, the simplified "if" conditional can be:
`if ((conditions & ChannelCondition.EXIT_STATUS) != 0) {
break;
}`
This proposed work can be explained by quoting @likitha:
>CheckS2SVpnConnectionsCommand execution involves executing a script (checkbatchs2svpn.sh) in the virtual router. Once CS has opened a session to a virtual router and executed a script in the router, it waits indefinitely till the session either times out or the exit status of the remote process is available. But it is possible that an EOF is reached by the process in the router and the router never set the exit status.
>References -
>1. Some servers never send the exit status, or occasionally "forget" to do so (http://grepcode.com/file/repo1.maven.org/maven2/org.jvnet.hudson/trilead-ssh2/build212-hudson-1/com/trilead/ssh2/ChannelCondition.java).
>2. Get the exit code/status from the remote command - if available. Be careful - not all server implementations return this value - (http://grepcode.com/file/repo1.maven.org/maven2/org.jvnet.hudson/trilead-ssh2/build212-hudson-1/com/trilead/ssh2/Session.java#Session.waitForCondition%28int%2Clong%29).

Handle SSH if server "forget" to send exit status

File separator in windows is different from linux (the expected in the
test); thus, the test
*com.cloud.utils.SwiftUtilTest.testSplitSwiftPath()* will fail in
windows. The problem is that the input of the test is
*"container/object"* but the tested method uses the *File.separator*
(that depends from the OS), in the windows the tested method
(*com.cloud.utils.SwiftUtil.splitSwiftPath(String)*) looks for a "\" in
windows systems, resulting in an empty string and consequently a failure
in the test.
Some solutions:
- the simple way is to create a string `String input = "container" +
File.separator + "object";`, thus independent of the OS, the test will
succeed.
- a tricky solution is to mock the final static variable
*File.separator* and return "/".
I picked the easy way.
