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.
* CLOUDSTACK-10359: Change the inconsistent method names.

"getCustomized" is not as intuitive as "isCustomized".
"getIsSystem" is not as intuitive as "isSystem" as well.
* Add the missing changes of all usages of method getIsSystem.
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.

I found this empty test while working on other PRs. Empty/ignored tests do not help us. I am removing it. In the future, if we manage to improve these classes, we can work on unit test cases for them.
This allows CloudStack to use a console proxy domain instead of public
IP address even when ssl is not enabled but console proxy url/domain
is defined in global settings.

* [CLOUDSTACK-10230] User is able to change to “Guest OS type” that has been removed
Users are able to change the OS type of VMs to “Guest OS type” that has been removed. This becomes a security issue when we try to force users to use HVM VMs (Meltdown/Spectre thing). A removed “guest os type” should not be usable by any users in the cloud.
* [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.
* Cleanups and formatting
Several fixes addressed:
- Dettach ISO fails when trying to detach a direct download ISO
- Fix for metalink support on SSVM agents (this closes CLOUDSTACK-10238)
- Reinstall VM from bypassed registered template (this closes CLOUDSTACK-10250)
- Fix upload certificate error message even though operation was successful
- Fix metalink download, checksum retry logic and metalink SSVM downloader
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-10240] ACS cannot migrate a volume from local to shared storage.
CloudStack is logically restricting the migration of local storages to shared storage and vice versa. This restriction is a logical one and can be removed for XenServer deployments. Therefore, we will enable migration of volumes between local-shared storages in XenServers independently of their service offering. This will work as an override mechanism to the disk offering used by volumes. If administrators want to migrate local volumes to a shared storage, they should be able to do so (the hypervisor already allows that). The same the other way around.
* Cleanups implemented while working on [CLOUDSTACK-10240]
* Fix test case test_03_migrate_options_storage_tags
The changes applied were:
- When loading hypervisors capabilities we must use "default" instead of nulls
- "Enable" storage migration for simulator hypervisor
- Remove restriction on "ClusterScopeStoragePoolAllocator" to find shared pools
This would make keystore utility scripts being executed as sudoer
in case the process uid/owner is not root but still a sudoer user.
Also fails addHost while securing a KVM host and if keystore fails to be
setup for any reason.
