CLOUDSTACK-9470: Fix for SshHelper - test_network_acl was failing on Vmware due to a bug in sshExecute, in which value returned was null and there was still stdout to consume. This fix addresses this problem, consuming stdout peoperly to return expected value in sshExecute
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.
Used extensively in the CloudStackVersionTest.

This reduced the Nio loop selector wait time, this way the selector will
check frequently (as much as 100ms per iteration) and handle any pending

Taking fast and efficient volume snapshots with XenServer (and your storage provider)A XenServer storage repository (SR) and virtual disk image (VDI) each have UUIDs that are immutable.
This poses a problem for SAN snapshots, if you intend on mounting the underlying snapshot SR alongside the source SR (duplicate UUIDs).
VMware has a solution for this called re-signaturing (so, in other words, the snapshot UUIDs can be changed).
This PR only deals with the CloudStack side of things, but it works in concert with a new XenServer storage manager created by CloudOps (this storage manager enables re-signaturing of XenServer SR and VDI UUIDs).
I have written Marvin integration tests to go along with this, but cannot yet check those into the CloudStack repo as they rely on SolidFire hardware.
If anyone would like to see these integration tests, please let me know.

- 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.

- Uses non-blocking socket config in NioClient and NioServer/NioConnection
- Scalable connectivity from agents and peer clustered-management server

Remove classes with no referencesI used UCDetector (http://www.ucdetector.org/) as a plugin for Eclipse. With this tool, I discovered a lot of code without any reference (variables, methods and classes).
Following the work that was done at [https://github.com/apache/cloudstack/pull/1448]; this pull request had the goal of removing some of these classes. To check if I wasn't missing anything I searched for any file that could reference some of those classes. As I haven't found any way of these classes being used, they were removed.

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:

This feature allows root administrators to define new roles and associate API
permissions to them.
A limited form of role-based access control for the CloudStack management server
API is provided through a properties file, commands.properties, embedded in the
WAR distribution. Therefore, customizing API permissions requires unpacking the
distribution and modifying this file consistently on all servers. The old system
also does not permit the specification of additional roles.
FS:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Dynamic+Role+Based+API+Access+Checker+for+CloudStack
DB-Backed Dynamic Role Based API Access Checker for CloudStack brings following
changes, features and use-cases:
- Moves the API access definitions from commands.properties to the mgmt server DB
- Allows defining custom roles (such as a read-only ROOT admin) beyond the
current set of four (4) roles
- All roles will resolve to one of the four known roles types (Admin, Resource
Admin, Domain Admin and User) which maintains this association by requiring
all new defined roles to specify a role type.
- Allows changes to roles and API permissions per role at runtime including additions or
removal of roles and/or modifications of permissions, without the need
of restarting management server(s)
Upgrade/installation notes:
- The feature will be enabled by default for new installations, existing
deployments will continue to use the older static role based api access checker
with an option to enable this feature
- During fresh installation or upgrade, the upgrade paths will add four default
roles based on the four default role types
- For ease of migration, at the time of upgrade commands.properties will be used
to add existing set of permissions to the default roles. cloud.account
will have a new role_id column which will be populated based on default roles
as well
Dynamic-roles migration tool: scripts/util/migrate-dynamicroles.py
- Allows admins to migrate to the dynamic role based checker at a future date
- Performs a harder one-way migrate and update
- Migrates rules from existing commands.properties file into db and deprecates it

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.

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.
Continued the work started by https://github.com/likitha
commit (b9181c6) from PR #561.
CS waits indefinitely for CheckS2SVpnConnectionsComm and to return.
While remote executing commands through ssh, handle channel condition of
EOF because we wait for the the condition.
The SshHelper of the PR #561 is of another path from the
current master, its path was
https://github.com/likitha/cloudstack/commits/CLOUDSTACK-8611/utils/src/com/cloud/utils/ssh/SshHelper.java;
thus, although this commit brings changes from PR #561, I did not
cherry-picked to keep the master file, otherwise it would look that I
had changed all the file.

Factor in inaccurancy of System.nanoTime in class ProfilerThe time diff measurement by the class Profiler, is done by System.nanoTime().
System.nanoTime() is not 100% accurate (lots of info on this on the web). The inaccurance seems to vary/depend with different dependencies (multi-core/OS/kernels).
Problem:
In my case the code which measures `Thread.sleep(ONE_SECOND);` ~~takes~~ measures 999 milliseconds, which breaks the test expecting the sleep of 1000 milliseconds to ~~take~~ measure at least 1000 milliseconds.
Solution:
A `MARGIN` (of 100 milliseconds) is already present to factor in some time for overhead/surrounding code which adds time. Another margin could be added to factor in the possible time measurement error.
To limit additional lines of code, the constant `ONE_SECOND`, which is used by the testcase (sleep), is increased from 1000 milliseconds to `1000l + (MARGIN / 10)` (effectively 1010 milliseconds).
Thereby the inaccurancy on my system of ~1% ("faster") is caught as the `sleep(1010)` is measured as '1009' milliseconds.

Given that the method com.cloud.utils.net.NetUtils.cidrToLong(String)
now throws an exception when receiving null or empty cidrs, there is the
need to change methods that use it. Those methods were changed and test
cases created.
The S3 implementation is far from finished, this commit focusses on the bases.
- Upgrade AWS SDK to latest version.
- Rewrite S3 Template downloader.
- Rewrite S3Utils utility class.
- Improve addImageStoreS3 API command.
- Split various classes for convenience.
- Various minor improvements and code optimalisations.
A side effect of the new AWS SDK is that it, by default, uses the V4 signature. Therefore I added an option to specify the Signer, so it stays compatible with previous versions.
These were lacking, but this helper is used in various places

Proposal for an improved CglibThrowableRendererFollowing our discussions on mailing list, here is a PR with a proposal for an improvement on CglibThrowableRenderer. We would still have to define a number to limit the stack traces of causes (I randomly chose 3, just to get the code running). The test case is also not good in my opinion, but I ran out of ideas (waiting for suggestions on that).

Changed the test case to test each of the log traces in the array list.

- Login is based on sessionkey HttpOnly Cookie
- ApiServlet does login verification using sessionKey from both the request cookies
and the API parameters. In both cases, if either or both are passed they should
match the sessionKey stored in the current session of the HttpRequest
- UI: it no longer needs to read or set sessionkey cookie
- UI: it no longer needs to return g_sessionKey value in the API requests, though
to support a sso mechanism g_sessionKey is still passed in the API is not null
- Secure jsessionid cookie is set to be HttpOnly and Secure
- SAML login should also set HttpOnly cookie before redirecting to UI
- SAML: listIdps & getSPMetadata APIs are readonly now, won't log out a logged in user
Performed tests (login, saml login if applicable, page refreshes, opening
multiple tabs, logout) with following combinations:

* Before doing SAML auth, cleanup local states and cookies
* Fix configurations in 4.5.1 to 4.5.2 upgrade path
* Fail if idp has no sso URL defined
* Add a default set of SAML SP cert for testing purposes
Now to enable and use saml, one needs to do a deploydb-saml after doing a deploydb
* UI remembers login selections, IDP server
- CLOUDSTACK-8458:
* On UI show dropdown list of discovered IdPs
* Support SAML Federation, where there may be more than one IdP
- New datastructure to hold metadata of SP or IdP
- Recursive processing of IdP metadata
- Fix login/logout APIs to get new interface and metadata data structure
- Add org/contact information to metadata
- Add new API: listIdps that returns list of all discovered IdPs
- Refactor and cleanup code and tests
- CLOUDSTACK-8459:
* Add HTTP-POST binding to SP metadata
* Authn requests must use either HTTP POST/Artifact binding
- CLOUDSTACK-8461:
* Use unspecified x509 cert as a fallback encryption/signing key
In case a IDP's metadata does not clearly say if their certificates need to be
used as signing or encryption and we don't find that, fallback to use the
unspecified key itself.
- CLOUDSTACK-8462:
* SAML Auth plugin should not do authorization
This removes logic to create user if they don't exist. This strictly now
assumes that users have been already created/imported/authorized by admins.
As per SAML v2.0 spec section 4.1.2, the SP provider should create authn requests using
either HTTP POST or HTTP Artifact binding to transfer the message through a
user agent (browser in our case). The use of HTTP Redirect was one of the reasons
why this plugin failed to work for some IdP servers that enforce this.
* Add new User Source
By reusing the source field, we can find if a user has been SAML enabled or not.
The limitation is that, once say a user is imported by LDAP and then SAML
enabled - they won't be able to use LDAP for authentication
* UI should allow users to pass in domain they want to log into, though it is
optional and needed only when a user has accounts across domains with same
username and authorized IDP server
* SAML users need to be authorized before they can authenticate
- New column entity to track saml entity id for a user
- Reusing source column to check if user is saml enabled or not
- Add new source types, saml2 and saml2disabled
- New table saml_token to solve the issue of multiple users across domains and
to enforce security by tracking authn token and checking the samlresponse for
the tokens
- Implement API: authorizeSamlSso to enable/disable saml authentication for a
user
- Stubs to implement saml token flushing/expiry
- CLOUDSTACK-8463:
* Use username attribute specified in global setting
Use username attribute defined by admin from a global setting
In case of encrypted assertion/attributes:
- Decrypt them
- Check signature if provided to check authenticity of message using IdP's
public key and SP's private key
- Loop through attributes to find the username
- CLOUDSTACK-8538:
* Add new global config for SAML request sig algorithm
- CLOUDSTACK-8539:
* Add metadata refresh timer task and token expiring
- Fix domain path and save it to saml_tokens
- Expire hour old saml tokens

The fix generates X509Certificate if missing from DB and uses that for eternity.
SAML SP metadata remains same since it's using the same X509 certificate and
it remains same after restarts. The certificate is serialized, base64 encoded

On hosts or containers where they don't have valid mac address on nic resulting
in null, NetUtils.getNetworkParam can throw NPE.
This was a case found on TravisCI where OpenVZ containers are used. This method
(getDefaultHostIp) is used at several other places within the ACS codebase to
get the host IP and if null is caught we fallback to localhost or 127.0.0.1, so
we therefore set info to null before trying to process network param and if we
fail we return null and expect other layers to use localhost.

For some reason the mgmt server is required to have access to the template
being registered in order to check its size against resource limits
during registration. This is bad, but worse, it's a sync call, so this
call can hang for up to the default HTTP connection timeout.
Reducing http timeout as a quick workaround, but this check needs to
1) be removed or 2) done later or 3)registerTemplate needs to be async
and 4) moved off the mgmt server (ssvm is the only thing that needs access to
template url).
This patch adds support for trust chains in the netscaler.
I initially planned on using the 10.1 API's "bundle" feature but during
my testing I found that was not working. So I am doing the chain linking
myself. Also NS can have only one entity of a certificate ie lets say
two different users try to add the same certificate on the netscaler
only one of them will go through. The other one says resouce already
exists even though they have different files.
This can be a problem in trust chains where the chain can be shared
between multiple accounts/certificates. So, I am using the figerprint as
an identifier of a certificate and making sure that we delete it only
when no one references it.
