Changes in PR #2508 have caused network restart to fail in a Nuage setup,
as the new VR takes the same IP as the old one, and the old VR is still running.
Nuage doesn't support multiple VM's having the same IP.
We delay provisioning the interfaces in VSD until the old VR interface is released.
This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be false causing them to be hosted on secondary storage. The current support is limited from hypervisor resource side and in current implementation limited to `KVM` only. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding genisoimage dependency on cloudstack-agent pkg.
The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased configdrive. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them.

* CLOUDSTACK-9184: Fixes#2631 VMware dvs portgroup autogrowth
This deprecates the vmware.ports.per.dvportgroup global setting.
The vSphere Auto Expand feature (introduced in vSphere 5.0) will take
care of dynamically increasing/decreasing the dvPorts when running out
of distributed ports . But in case of vSphere 4.1/4.0 (If used), as this
feature is not there, the new default value (=> 8) have an impact in the
existing deployments. Action item for vSphere 4.1/4.0: Admin should
modify the global configuration setting "vmware.ports.per.dvportgroup"
from 8 to any number based on their environment because the proposal
default value of 8 would be very less without auto expand feature in
general. The current default value of 256 may not need immediate
modification after deployment, but 8 would be very less which means
admin need to update immediately after upgrade.

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!

When cache mode 'none' is used for empty cdrom drives, systemvms

The fix is ensure that cachemode is not declared when drives are empty
upon starting of the VM. Similar issue logged at redhat here:

The workaround is to ensure that we don't configure cachemode for

CloudStack SSO (using security.singlesignon.key) does not work anymore with CloudStack 4.11, since commit 9988c26, which introduced a regression due to a refactoring: every API request that is not "validated" generates the same error (401 - Unauthorized) and invalidates the session.
However, CloudStack UI executes a call to listConfigurations in method bypassLoginCheck. A non-admin user does not have the permissions to execute this request, which causes an error 401:
{"listconfigurationsresponse":{"uuidList":[],"errorcode":401,"errortext":"unable to verify user credentials and/or request signature"}}
The session (already created by SSO) is then invalidated and the user cannot access to CloudStack UI (error "Session Expired").
Before 9988c26 (up to CloudStack 4.10), an error 432 was returned (and ignored):
{"errorresponse":{"uuidList":[],"errorcode":432,"cserrorcode":9999,"errortext":"The user is not allowed to request the API command or the API command does not exist"}}
Even if the call to listConfigurations was removed, another call to listIdps also lead to an error 401 for user accounts if the SAML plugin is not enabled.
This pull request aims to fix the SSO issue, by restoring errors 432 (instead of 401 + invalidate session) for commands not available. However, if an API command is explicitly denied using ACLs or if the session key is incorrect, it still generates an error 401 and invalidates the session.
This extends securing of KVM hosts to securing of libvirt on KVM
host as well for TLS enabled live VM migration. To simplify implementation
securing of host implies that both host and libvirtd processes are
secured with management server's CA plugin issued certificates.
Based on whether keystore and certificates files are available at
/etc/cloudstack/agent, the KVM agent determines whether to use TLS or
TCP based uris for live VM migration. It is also enforced that a secured
host will allow live VM migration to/from other secured host, and an
unsecured hosts will allow live VM migration to/from other unsecured
host only.
Post upgrade the KVM agent on startup will expose its security state
(secured detail is sent as true or false) to the managements server that
gets saved in host_details for the host. This host detail can be accesed
via the listHosts response, and in the UI unsecured KVM hosts will show
up with the host state of ‘unsecured’. Further, a button has been added
that allows admins to provision/renew certificates to KVM hosts and can
be used to secure any unsecured KVM host.
The `cloudstack-setup-agent` was modified to accept a new flag `-s`
which will reconfigure libvirtd with following settings:
listen_tcp=0
listen_tls=1
tcp_port="16509"
tls_port="16514"
auth_tcp="none"
auth_tls="none"
key_file = "/etc/pki/libvirt/private/serverkey.pem"
cert_file = "/etc/pki/libvirt/servercert.pem"
ca_file = "/etc/pki/CA/cacert.pem"
For a connected KVM host agent, when the certificate are
renewed/provisioned a background task is scheduled that waits until all
of the agent tasks finish after which libvirt process is restarted and
finally the agent is restarted via AgentShell.
There are no API or DB changes.

* [CLOUDSTACK-10226] CloudStack is not importing Local storage properly
CloudStack is importing as Local storage any XenServer SR that is of type LVM or EXT. This causes a problem when one wants to use both Direct attach storage and local storage. Moreover, CloudStack was not importing all of the local storage that a host has available when local storage is enabled. It was only importing the First SR it sees.
To fix the first problem we started ignoring SRs that have the flag shared=true when discovering local storages. SRs configured to be shared are used as direct attached storage, and therefore should not be imported again as local ones.
To fix the second problem, we started loading all Local storage and importing them accordingly to ACS.

* [CLOUDSTACK-10241] Duplicated file SRs being created in XenServer pools
Due to a race condition between multiple management servers, in some rare cases, CloudStack is creating multiple file SRs to the same secondary folder. This causes a problem when introducing the SR to the XenServer pools, as “there will be VDIs with duplicated UUIDs“. The VDIs are the same, but they are seen in different SRs, and therefore cause an error.
The solution to avoid race conditions between management servers is to use a deterministic srUuid for the file SR to be created (we are leaving XenServer with the burden of managing race conditions). The UUID is based on the SR file path and is generated using UUID#nameUUIDFromBytes. Therefore, if there is an SR with the generated UUID, this means that some other management server has just created it. An exception will occur and it will contain a message saying 'Db_exn.Uniqueness_constraint_violation'. In these unlikely events, we catch the exception and use the method retrieveAlreadyConfiguredSrWithoutException to get the SR that has already been created for the given mount point.

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.

There is a race condition in the monitoring of the migration process on KVM. If the monitor wakes up in the tight window after the migration succeeds, but before the migration thread terminates, the monitor will get a LibvirtException “Domain not found: no domain with matching uuid” when checking on the migration status. This in turn causes CloudStack to sync the VM state to stop, in which it issues a defensive StopCommand to ensure it is correctly synced.

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 feature allows using templates and ISOs avoiding secondary storage as intermediate cache on KVM. The virtual machine deployment process is enhanced to supported bypassed registered templates and ISOs, delegating the work of downloading them to primary storage to the KVM agent instead of the SSVM agent.
Template and ISO registration:
- When hypervisor is KVM, a checkbox is displayed with 'Direct Download' label.
- API methods registerTemplate and registerISO are both extended with this new parameter directdownload.
- On template or ISO registration, no download job is sent to SSVM agent, CloudStack would only persist an entry on template_store_ref indicating that template or ISO has been marked as 'Direct Download' (bypassing Secondary Storage). These entries are persisted as:
template_id = Template or ISO id on vm_template table
store_id NULL
download_state = BYPASSED
state = Ready
(Note: these entries allow users to deploy virtual machine from registered templates or ISOs)
- An URL validation command is sent to a random KVM host to check if template/ISO location can be reached. Metalink are also supported by this feature. In case of a metalink, it is fetched and URL check is performed on each of its URLs.
- Checksum should be provided as indicated on #2246: {ALGORITHM}CHKSUMHASH
- After template or ISO is registered, it would be displayed in the UI
Virtual machine deployment:
When a 'Direct Download' template is selected for deployment, CloudStack would delegate template downloading to destination storage pool via destination host by a new pluggable download manager.
Download manager would handle template downloading depending on URL protocol. In case of HTTP, request headers can be set by the user via vm_template_details. Those details should be persisted as:
Key: HTTP_HEADER
Value: HEADERNAME:HEADERVALUE
In case of HTTPS, a new API method is added uploadTemplateDirectDownloadCertificate to allow user importing a client certificate into all KVM hosts' keystore before deployment.
After template or ISO is downloaded to primary storage, usual entry would be persisted on template_spool_ref indicating the mapping between template/ISO and storage pool.
This happens when the root disk size is overridden. The primary storage limit check should be performed based on overridden size instead of template size. Enabled root disk resize tests to run on simulator as well.
This feature allow admins to dedicate a range of public IP addresses to the SSVM and CPVM, such that they can be subject to specific external firewall rules. The option to dedicate a public IP range to the System VMs (SSVM & CPVM) is added to the createVlanIpRange API method and the UI.
Solution:
Global setting 'system.vm.public.ip.reservation.mode.strictness' is added to determine if the use of the system VM reservation is strict (when true) or preferred (false), false by default.
When a range has been dedicated to System VMs, CloudStack should apply IPs from that range to
the public interfaces of the CPVM and the SSVM depending on global setting's value:
If the global setting is set to false: then CloudStack will use any unused and unreserved public IP
addresses for system VMs only when the pool of reserved IPs has been exhausted
If the global setting is set to true: then CloudStack will fail to deploy the system VM when the pool
of reserved IPs has been exhausted, citing the lack of available IPs.
UI Changes
Under Infrastructure -> Zone -> Physical Network -> Public -> IP Ranges, button 'Account' label is refactored to 'Set reservation'.
When that button is clicked, dialog displayed is also refactored, including a new checkbox 'System VMs' which indicates if range should be dedicated for CPVM and SSVM, and a note indicating its usage.
When clicking on button for any created range, UI dialog displayed indicates whether IP range is dedicated for system vms or not.
The first PR(#1176) intended to solve #CLOUDSTACK-9025 was only tackling the problem for CloudStack deployments that use single hypervisor types (restricted to XenServer). Additionally, the lack of information regarding that solution (poor documentation, test cases and description in PRs and Jira ticket) led the code to be removed in #1124 after a long discussion and analysis in #1056. That piece of code seemed logicless (and it was!). It would receive a hostId and then change that hostId for other hostId of the zone without doing any check; it was not even checking the hypervisor and storage in which the host was plugged into.
The problem reported in #CLOUDSTACK-9025 is caused by partial snapshots that are taken in XenServer. This means, we do not take a complete snapshot, but a partial one that contains only the modified data. This requires rebuilding the VHD hierarchy when creating a template out of the snapshot. The point is that the first hostId received is not a hostId, but a system VM ID(SSVM). That is why the code in #1176 fixed the problem for some deployment scenarios, but would cause problems for scenarios where we have multiple hypervisors in the same zone. We need to execute the creation of the VHD that represents the template in the hypervisor, so the VHD chain can be built using the parent links.
This commit changes the method com.cloud.hypervisor.XenServerGuru.getCommandHostDelegation(long, Command). From now on we replace the hostId that is intended to execute the “copy command” that will create the VHD of the template according to some conditions that were already in place. The idea is that starting with XenServer 6.2.0 hotFix ESP1004 we need to execute the command in the hypervisor host and not from the SSVM. Moreover, the method was improved making it readable and understandable; it was also created test cases assuring that from XenServer 6.2.0 hotFix ESP1004 and upward versions we change the hostId that will be used to execute the “copy command”.
Furthermore, we are not selecting a random host from a zone anymore. A new method was introduced in the HostDao called “findHostConnectedToSnapshotStoragePoolToExecuteCommand”, using this method we look for a host that is in the cluster that is using the storage pool where the volume from which the Snaphost is taken of. By doing this, we guarantee that the host that is connected to the primary storage where all of the snapshots parent VHDs are stored is used to create the template.
Consider using Disabled hosts when no Enabled hosts are found

* Cleanup and Improve NetUtils
This class had many unused methods, inconsistent names and redundant code.
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.

This feature allows CloudStack administrators to create layer 2 networks on CloudStack. As these networks are purely layer 2, they don't require IP addresses or Virtual Router, only VLAN is necessary (provided by administrator or assigned by CloudStack). Also, network services should be handled externally, e.g. DNS, DHCP, as they are not provided by L2 networks.
As a consequence, a new Guest Network type is created within CloudStack: L2
Description:
Network offerings and networks support new guest type: L2.
L2 Network offering creation allows administrator to select Specify VLAN or let CloudStack assign it dynamically.
L2 Network creation allows administrator to specify VLAN tag (if network offerings allows it) or simply create network.
VM deployments on L2 networks:
VMs should not IP addresses or any network service
No Virtual Router deployed on network
If Specify VLAN = true for network offering, network gets implemented using a dynamically assigned VLAN
UI changes
A new button is added on Networks tab, available for admins, to allow L2 networks creation

The listNuageVspDomainTemplat cmd was called by the ui when the create vpc dialog was opened. This command failed when no nuage vsp device was present. As a consequence the ui did not show the dialog. So currently it's not possible to create a vpc through the UI with a native CloudStack deployment. This bugfix, adds robustness to the ui that in case the cmd fails the dialog will appear nonetheless . Furthermore I also changed the listNuageVspDomainTemplateCmd to always return an empty result when there is no nuage zone.

Allow security policies to apply on port groups:
- Accepts security policies while creating network offering
- Deployed network will have security policies from the network offering
applied on the port group (in vmware environment)
- 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 commit is related to the Saml2 user authentication plugin.
The user can list its domains. His/Her domains are presented as the
following example:
username/subdomainA
username/subdomainB
However, if a user has two subdomains of the same name Dom1/subdomainA
and Dom2/subdomainA, the list is presented as follows:
username/subdomainA
username/subdomainA
With this commit it shows the full domain name to avoid such cases.
Thus, the domains will be presented as follows:
username/Dom1/subdomainA
username/Dom2/subdomainA
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 causes VM deployment failure on the host that was disabled while adding the storage repository.
In the attachCluster function of the PrimaryDataStoreLifeCycle, we were only selecting hosts that are up and are in enabled state. Here if we select all up hosts, it will populate the DB properly and will fix this issue. Also added a unit test for attachCluster function.
If there are multiple files with the same name on vmware datastore, search operation may select any one file during volume related operations. This involves volume attach/detach, volume download, volume snapshot etc.
While using NetApp as the backup solution. This has .snapshot folder on the datastore and sometimes files from this folder gets selected during volume operations and the operation fails. Because of wrong selection of file following exception can be observed while volume deletion.
2017-02-23 19:39:05,750 ERROR [c.c.s.r.VmwareStorageProcessor] (DirectAgent-304:ctx-a1dbf5d8 ac.local) delete volume failed due to Exception: java.lang.RuntimeException
