With the StarlingX move to supporting pure upstream OpenStack, the majority of the SDK Modules are related to functionality no longer supported. The remaining SDK Modules will be moved to StarlingX documentation.

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION |
||||
|
||||
1. Definitions. |
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction, |
||||
and distribution as defined by Sections 1 through 9 of this document. |
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by |
||||
the copyright owner that is granting the License. |
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all |
||||
other entities that control, are controlled by, or are under common |
||||
control with that entity. For the purposes of this definition, |
||||
"control" means (i) the power, direct or indirect, to cause the |
||||
direction or management of such entity, whether by contract or |
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the |
||||
outstanding shares, or (iii) beneficial ownership of such entity. |
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity |
||||
exercising permissions granted by this License. |
||||
|
||||
"Source" form shall mean the preferred form for making modifications, |
||||
including but not limited to software source code, documentation |
||||
source, and configuration files. |
||||
|
||||
"Object" form shall mean any form resulting from mechanical |
||||
transformation or translation of a Source form, including but |
||||
not limited to compiled object code, generated documentation, |
||||
and conversions to other media types. |
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or |
||||
Object form, made available under the License, as indicated by a |
||||
copyright notice that is included in or attached to the work |
||||
(an example is provided in the Appendix below). |
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object |
||||
form, that is based on (or derived from) the Work and for which the |
||||
editorial revisions, annotations, elaborations, or other modifications |
||||
represent, as a whole, an original work of authorship. For the purposes |
||||
of this License, Derivative Works shall not include works that remain |
||||
separable from, or merely link (or bind by name) to the interfaces of, |
||||
the Work and Derivative Works thereof. |
||||
|
||||
"Contribution" shall mean any work of authorship, including |
||||
the original version of the Work and any modifications or additions |
||||
to that Work or Derivative Works thereof, that is intentionally |
||||
submitted to Licensor for inclusion in the Work by the copyright owner |
||||
or by an individual or Legal Entity authorized to submit on behalf of |
||||
the copyright owner. For the purposes of this definition, "submitted" |
||||
means any form of electronic, verbal, or written communication sent |
||||
to the Licensor or its representatives, including but not limited to |
||||
communication on electronic mailing lists, source code control systems, |
||||
and issue tracking systems that are managed by, or on behalf of, the |
||||
Licensor for the purpose of discussing and improving the Work, but |
||||
excluding communication that is conspicuously marked or otherwise |
||||
designated in writing by the copyright owner as "Not a Contribution." |
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity |
||||
on behalf of whom a Contribution has been received by Licensor and |
||||
subsequently incorporated within the Work. |
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of |
||||
this License, each Contributor hereby grants to You a perpetual, |
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
||||
copyright license to reproduce, prepare Derivative Works of, |
||||
publicly display, publicly perform, sublicense, and distribute the |
||||
Work and such Derivative Works in Source or Object form. |
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of |
||||
this License, each Contributor hereby grants to You a perpetual, |
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
||||
(except as stated in this section) patent license to make, have made, |
||||
use, offer to sell, sell, import, and otherwise transfer the Work, |
||||
where such license applies only to those patent claims licensable |
||||
by such Contributor that are necessarily infringed by their |
||||
Contribution(s) alone or by combination of their Contribution(s) |
||||
with the Work to which such Contribution(s) was submitted. If You |
||||
institute patent litigation against any entity (including a |
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work |
||||
or a Contribution incorporated within the Work constitutes direct |
||||
or contributory patent infringement, then any patent licenses |
||||
granted to You under this License for that Work shall terminate |
||||
as of the date such litigation is filed. |
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the |
||||
Work or Derivative Works thereof in any medium, with or without |
||||
modifications, and in Source or Object form, provided that You |
||||
meet the following conditions: |
||||
|
||||
(a) You must give any other recipients of the Work or |
||||
Derivative Works a copy of this License; and |
||||
|
||||
(b) You must cause any modified files to carry prominent notices |
||||
stating that You changed the files; and |
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works |
||||
that You distribute, all copyright, patent, trademark, and |
||||
attribution notices from the Source form of the Work, |
||||
excluding those notices that do not pertain to any part of |
||||
the Derivative Works; and |
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its |
||||
distribution, then any Derivative Works that You distribute must |
||||
include a readable copy of the attribution notices contained |
||||
within such NOTICE file, excluding those notices that do not |
||||
pertain to any part of the Derivative Works, in at least one |
||||
of the following places: within a NOTICE text file distributed |
||||
as part of the Derivative Works; within the Source form or |
||||
documentation, if provided along with the Derivative Works; or, |
||||
within a display generated by the Derivative Works, if and |
||||
wherever such third-party notices normally appear. The contents |
||||
of the NOTICE file are for informational purposes only and |
||||
do not modify the License. You may add Your own attribution |
||||
notices within Derivative Works that You distribute, alongside |
||||
or as an addendum to the NOTICE text from the Work, provided |
||||
that such additional attribution notices cannot be construed |
||||
as modifying the License. |
||||
|
||||
You may add Your own copyright statement to Your modifications and |
||||
may provide additional or different license terms and conditions |
||||
for use, reproduction, or distribution of Your modifications, or |
||||
for any such Derivative Works as a whole, provided Your use, |
||||
reproduction, and distribution of the Work otherwise complies with |
||||
the conditions stated in this License. |
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise, |
||||
any Contribution intentionally submitted for inclusion in the Work |
||||
by You to the Licensor shall be under the terms and conditions of |
||||
this License, without any additional terms or conditions. |
||||
Notwithstanding the above, nothing herein shall supersede or modify |
||||
the terms of any separate license agreement you may have executed |
||||
with Licensor regarding such Contributions. |
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade |
||||
names, trademarks, service marks, or product names of the Licensor, |
||||
except as required for reasonable and customary use in describing the |
||||
origin of the Work and reproducing the content of the NOTICE file. |
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or |
||||
agreed to in writing, Licensor provides the Work (and each |
||||
Contributor provides its Contributions) on an "AS IS" BASIS, |
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or |
||||
implied, including, without limitation, any warranties or conditions |
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A |
||||
PARTICULAR PURPOSE. You are solely responsible for determining the |
||||
appropriateness of using or redistributing the Work and assume any |
||||
risks associated with Your exercise of permissions under this License. |
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory, |
||||
whether in tort (including negligence), contract, or otherwise, |
||||
unless required by applicable law (such as deliberate and grossly |
||||
negligent acts) or agreed to in writing, shall any Contributor be |
||||
liable to You for damages, including any direct, indirect, special, |
||||
incidental, or consequential damages of any character arising as a |
||||
result of this License or out of the use or inability to use the |
||||
Work (including but not limited to damages for loss of goodwill, |
||||
work stoppage, computer failure or malfunction, or any and all |
||||
other commercial damages or losses), even if such Contributor |
||||
has been advised of the possibility of such damages. |
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing |
||||
the Work or Derivative Works thereof, You may choose to offer, |
||||
and charge a fee for, acceptance of support, warranty, indemnity, |
||||
or other liability obligations and/or rights consistent with this |
||||
License. However, in accepting such obligations, You may act only |
||||
on Your own behalf and on Your sole responsibility, not on behalf |
||||
of any other Contributor, and only if You agree to indemnify, |
||||
defend, and hold each Contributor harmless for any liability |
||||
incurred by, or claims asserted against, such Contributor by reason |
||||
of your accepting any such warranty or additional liability. |
||||
|
||||
END OF TERMS AND CONDITIONS |
||||

||||
APPENDIX: How to apply the Apache License to your work. |

DESCRIPTION |
||||
=========== |
||||
|
||||
Server Group Messaging is a service to provide simple low-bandwidth datagram |
||||
messaging and notifications for servers that are part of the same server group. |
||||
This messaging channel is available regardless of whether IP networking is |
||||
functional within the server, and it requires no knowledge within the server |
||||
about the other members of the group. |
||||
|
||||
The service provides three types of messaging: |
||||
1) Broadcast: this allows a server to send a datagram (size of up to 3050 bytes) |
||||
to all other servers within the server group. |
||||
|
||||
2) Notification: this provides servers with information about changes to the |
||||
state of other servers within the server group. |
||||
|
||||
3) Status: this allows a server to query the current state of all servers within |
||||
the server group (including itself). |
||||
|
||||
This service is not intended for high bandwidth or low-latency operations. It |
||||
is best-effort, not reliable. Applications should do end-to-end acks and |
||||
retries if they care about reliability. |
||||
|
||||
|
||||
REQUIREMENTS |
||||
============ |
||||
Compilation: |
||||
Linux OS, x86_64 architecture |
||||
gcc compiler |
||||
development libraries and headers for glibc |
||||
development libraries and headers for json-c |
||||
|
||||
VM Runtime: |
||||
Linux OS, x86_64 architecture |
||||
runtime libraries for glibc |
||||
runtime libraries for json-c |
||||
|
||||
The code has been tested with glibc 2.15, gcc 4.6 and json-c 0.12.99 but it |
||||
should run on other versions without difficulty. |
||||
|
||||
|
||||
DELIVERABLE |
||||
=========== |
||||
The Server Group Messaging service is delivered as source with the |
||||
required makefiles in a compressed tarball called |
||||
"wrs-server-group-2.0.0.tgz", such that it can be compiled for the applicable |
||||
guest linux distribution. |
||||
|
||||
|
||||
COMPILE |
||||
======= |
||||
Install the prerequisites: |
||||
On CentOS/RHEL: yum install json-c-devel make gcc glibc-devel |
||||
On Ubuntu/Debian: sudo apt-get install build-essential libjson0-dev |
||||
|
||||
Extract the tarball contents: |
||||
tar xvf wrs-server-group-#.#.#.tgz |
||||
|
||||
To compile: |
||||
cd wrs-server-group-#.#.# |
||||
make |
||||
export WRS_SERVER_GROUP_DIR=${PWD} |
||||
|
||||
This will produce: |
||||
|
||||
1) An executable "bin/guest_agent". This acts as a relay between the guest and |
||||
the host. This executable must be installed into the guest and configured to |
||||
run at startup. It should be configured to respawn (via /etc/inittab or some |
||||
other process monitor) if it dies for any reason. |
||||
|
||||
Typical manual installation commands: |
||||
sudo cp bin/* /usr/sbin |
||||
sudo cp scripts/guest-agent.service /lib/systemd/system/ |
||||
sudo systemctl enable guest-agent.service |
||||
sudo systemctl start guest-agent.service |
||||
|
||||
2) A library "lib/libservergroup.so.2.0.*". This encapsulates the details of |
||||
talking to the guest agent. This can be used with the header file |
||||
"server_group.h" to create custom applications that can make use of the |
||||
messaging service. This should be installed within the guest in a suitable |
||||
library location such that the linker can find it. It should also be installed |
||||
in the build system where custom applications can link against it. The |
||||
"libservergroup.so.2" symlink should be created in the build system and the |
||||
guest, and the "libservergroup.so" symlink should be created in the build |
||||
system, either by ldconfig or some other means. |
||||
|
||||
Typical manual installation commands: |
||||
sudo cp -P lib/libservergroup.* /usr/lib/ |
||||
sudo ldconfig |
||||
|
||||
3) A header file "include/cgcs/server_group.h". This is used along with the library to |
||||
create custom applications that can make use of the messaging service. This |
||||
should be installed in the build system where custom applications can include |
||||
it. |
||||
|
||||
4) A sample program "bin/server_group_app" is created in order to show the use |
||||
of the APIs and validate that they are working properly in the guest. |
||||
|
||||
5) A library "lib/libguesthostmsg.so.2.0.*". This library is used by |
||||
wrs-guest-scale component packaged separately. This can be used with the |
||||
header file "guest_host_msg.h". This should be installed within |
||||
the guest in a suitable library location such that the linker can find it. |
||||
It should also be installed in the build system where custom applications can |
||||
link against it. The "libguesthostmsg.so.2" symlink should be created in the |
||||
build system and the guest, and the "libguesthostmsg.so" symlink should be |
||||
created in the build system, either by ldconfig or some other means. |
||||
|
||||
Typical manual installation commands: |
||||
sudo cp -P lib/libguesthostmsg.* /usr/lib/ |
||||
sudo ldconfig |
||||
|
||||
6) A header file "include/cgcs/guest_host_msg.h". This is used along with |
||||
the library to create custom applications that can make use of the messaging |
||||
service. This should be installed in the build system where custom |
||||
applications can include it. (Setting the WRS_SERVER_GROUP_DIR environment as above |
||||
variable will allow it to be found when building the wrs-guest-scale component.) |
||||
|
||||
|
||||
Note: |
||||
The inclusion of the files into the build system and the guest image and the |
||||
configuration of the guest startup scripts is left up to the user to allow for |
||||
different build systems and init subsystems in the guest. |
||||
|
||||
|
||||
INSTALL |
||||
======= |
||||
Installing in a running VM: |
||||
|
||||
As the root user |
||||
1) Copy "bin/guest_agent" and any other desired binaries such as |
||||
"bin/server_group_app" to /usr/sbin in the VM. |
||||
|
||||
2) Run "cp -P lib/* /usr/lib" (or /usr/lib64 as appropriate) in the VM |
||||
to install the libraries. |
||||
|
||||
3) Run "ldconfig". |
||||
|
||||
4) Copy scripts/guest-agent.service to /lib/systemd/system/ and then run |
||||
"systemctl enable guest-agent.service" and "systemctl start guest-agent.service". |
||||
This should cause the "guest-agent" binary to start running. |
||||
|
||||
5) Applications can now make use of the service. |
||||
|
||||
6) Run "cp -r include/cgcs /usr/include/" to set up the headers for anyone |
||||
wanting to link against libservergroup or libguesthostmsg. |
||||
|
||||
As part of building the VM ISO Image: |
||||
|
||||
1) Ensure "bin/guest_agent" and any other desired binaries get installed |
||||
to /usr/sbin in the VM filesystem. |
||||
|
||||
2) Ensure "lib/*" gets installed to /usr/lib64 in the VM filesystem. |
||||
|
||||
3) Ensure that "ldconfig" will run at VM startup. |
||||
|
||||
4) Ensure that "/usr/sbin/guest_agent" is configured to run automatically |
||||
at VM startup and to respawn if it dies for any reason. The scripts/ |
||||
guest_agent.service file is provided for use by systemd. |
||||
|
||||
|
||||
USAGE |
||||
===== |
||||
The service is designed to be simple to use. A basic description is given |
||||
below, but more details are provided in the header file. |
||||
|
||||
First, the application must call init_sg(). This call takes three function |
||||
pointers corresponding to callbacks for the various message types. If an |
||||
application doesn't intend to use one or more of the message types then the |
||||
appropriate function pointers can be specified as NULL. The function returns a |
||||
socket that must be monitored for activity using select/poll/etc. |
||||
|
||||
When the socket becomes readable, the application must call process_sg_msg(). |
||||
This may result in callbacks being called so be careful about deadlock. |
||||
|
||||
In order to send a broadcast message to every server in the server group, the |
||||
application can call sg_msg_broadcast(). |
||||
|
||||
In order to request the status of all servers in the group, the application can |
||||
call sg_request_status(). |
||||
|
||||
The sg_broadcast_msg_handler_t() callback will be called when receiving a server |
||||
group broadcast message. It will be passed the message as well as a |
||||
null-terminated string containing the instance name of the sender. |
||||
|
||||
The sg_notification_msg_handler_t() callback will be called when receiving a |
||||
notification message indicating a status change in one of the members of the |
||||
server group. The msg is JSON-formatted, essentially the normal notification |
||||
that gets sent out by OpenStack's notification service, but with some |
||||
non-relevant information removed to keep the message shorter. |
||||
|
||||
The sg_status_msg_handler_t() callback will be called when receiving the |
||||
response to a status query. The message is a JSON-formatted list of |
||||
dictionaries, each of which represents a single server. |
||||
|
||||
|
||||
SAMPLE APPLICATION |
||||
================== |
||||
The "server_group_app" sample application can be used to test the various types |
||||
of messages. It takes one optional argument, consisting of a character string |
||||
in quotes. When run, it behaves as follows: |
||||
|
||||
1) It registers for all three callbacks. |
||||
2) If the optional argument was specified it sends that string as a server group |
||||
broadcast message. |
||||
3) It requests the group status. |
||||
4) It then goes into a loop waiting for incoming messages. Any incoming message |
||||
will be printed out along with information about the type of message. |
||||
|
||||
|
||||
The service can be validated as follows using the "server_group_app" sample |
||||
application: |
||||
a) Create a server group with the "affinity" scheduler policy. |
||||
b) Start up a server within the server group. |
||||
c) Run "server_group_app" in the first server. You should immediately see the |
||||
status response message containing information about that server. |
||||
d) Start up a second server within the server group. You should see |
||||
notification messages being received in the first server. |
||||
e) Run 'server_group_app "this is a test"' on the second server. You should see |
||||
"this is a test" received as a broadcast message on the first server. The |
||||
second server should show a status response with information about both |
||||
servers |
||||
f) Start up a third server within the server group. You should see |
||||
notification messages being received in the other two servers. |
||||
g) Run 'server_group_app "final test"' on the second server. You should see |
||||
"final test" received as a broadcast message on the other two servers. The |
||||
second server should show a status response with information about all three |
||||
servers |

Notes on virtio-serial in guest: |
||||
1) The fact that POLLHUP is always set in revents when host connection is down |
||||
means that the only way to get event-driven notification of connection is to |
||||
register for SIGIO. However, then we get a SIGIO every time the device becomes |
||||
readable. The solution is to selectively block SIGIO as long as we think the link |
||||
is up, then unblock it so we get notified when the link comes back. |
||||
|
||||
2) If the host disconnects we will still process any buffered messages from it. |
||||
|
||||
3) If read() returns 0 or write() returns -1 with errno of EAGAIN that means |
||||
the host is disconnected. |
