Open Source Software Manifest Retrieval from a Headless Device
draft-beese-opsawg-ossman-00
Abstract
In commercial embedded systems utilizing open source, there are legal
requirements to make open source software utilized in a product
known. Headless devices have no UI to display an open source
manifest. Additionally, printed manuals become out of date as
software updates occur throughout the product lifetime. This
standard intends to create a common method of retrieving open source
manifests directly from an embedded device utilizing Ethernet or Wi-
Fi.

INTERNET DRAFT O.S.S. Manifests from Headless Devices March 31, 2016
1 Introduction
To comply with various governmental legal requirements around using
open source software, it is fairly routine to make open source
software manifests available to anyone asking for it. On devices
with built-in displays, the display can visually present the user
with an open source manifest. However, on headless devices, another
mechanism must be used.
This draft outlines a few methods make the open source mainfest
readily available through the embedded device's communications ports.
1.1 Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
O.S.S. stands for Open Source Software.

2. Protocol
If the device has an ethernet connection, the user may attach a
mobile device to the device utilizing ethernet. Likewise, if Wi-Fi
is in use, the user could attach a mobile device to the same Access
Point the device is on [or attach to the embedded device acting as an
access point].
To remove the reliance on IP addressing schemes, a multicast address
and associated UDP port number is suggested: 239.79.83.83
[239.O.S.S] and port YYYYY.
A request from the client to port YYYYY on 239.79.83.83 with any
payload will trigger a multicast reply to the same multicast IP
address on 239.79.83.83 and port YYYYY containing a JSON document:
{"oss": {
"<Package Name>": {
"Version": "<Version>",
"License Type": "<License Type>",
"URL": "<URL>",
[...]
}
"<Package Name2>": {
"Version": "<Version>",
"License Type": "<License Type>",
"URL": "<URL>",
[...]
}
}}
The user's mobile device may collect all responses from any devices
on a subnet and display results to the user.
3 Security Considerations
UDP listening port only listens for multicast on port XXXXX. Replies
can be throttled to only allow Y datagrams per second to prevent
flooding attacks.
4 IANA Considerations
Port number XXXXX should be reserved for this protocol standard.
Multicast IP Address 239.79.83.83 should be reserved for this
protocol standard.
