ipOS is the  Operating System developed by Ubicom. 

Latest SDK release is 7.10

Ubicom IP5000/IP7000 Software Development Kit

Release notes for SDK 7.10 23-January-2009


New features:
--------------------------------------------------------------------------------

Support for ip7000 silicon

Multiple profile support on the bridge

EV-MAC: (Everywhere Video MAC)
EV-MAC enhances quality of video delivery in the home by improving the reliability of the video stream. The reliability of video streams is improved through a combination of enhancements to the MAC layer algorithms, such as rate adaptation, packet aggregation, and wireless bandwidth allocation. These enhancements are made possible by automatically detecting bandwidth requirements of video streams and guaranteeing wireless bandwidth availability, even in the presence of background traffic.

Increased the number of simultaneous Bit Torrent connections by accelerating connection recycling under heavy router loads.

SMB/CIFS server capability integrated with the gateway_ip3k reference project such that we are able to serve files over the LAN-side network. The SMB server will serve these files from media attached via a USB connection. This was done by porting and optimizing Visuality SMB server to work on Ubicom CPU

Demo quality UPnP digital media server capability integrated with the gateway_ip3k reference project such that we are able to serve media files over the LAN-side network. The UPnP media server will serve these files from media attached via a USB connection. A subset of the features supported:
 

  • Can be enabled/disabled from the web UI.
  • Share folders can be added or all content can be shared with 1 click (currently max 10 folders, this is configurable)
  • Can serve multiple clients concurrently (as much as the network bandwidth and CPU power allows)
  • Design to conform to DLNA Guidelines v1.5, but we continue to see failures in the DLNA test suite
  • DMS version is 1.0 (this is the only version that exists)
  • Supports 2-Box Pull System model and 3-Box System model. (details are in the DD)
  • Browse capability
  • Search capability (only a subset is supported in order to make WMP11 work. The only supported search field is ‘upnp:class’ and that also limited)
  • HTTP transport: Streaming transfer mode & Interactive transfer mode
  • Multiple video, audio and picture format and containers are supported; full list can be made available though Ubicom application engineers
  • Client supported: WMP11, PS3, Ubicom DPF + several others.


Router enhancements:
--------------------------------------------------------------------------------

NAT:

ALG’s re-worked to make a clear separation between:
- CLASSIFYING a connection (as being handled by this ALG);
- Allowing a new connection for ‘unsolicited ingressing’ packets - the ALG may have knowledge that would allow packets that do not currently have a NAT connection to have one created for them; and
- Translating - normal job of an ALG to translate the payload of a stream

ALG classifiers and ‘unsolicited ingress’ handlers are no longer called by NAT or registered with NAT (they are more separate from NAT itself now). Only ALG connection handlers are registered with a NAT connection for fast path processing.
ALG classifiers and unsolicited ingress handlers are now invoked by the code in the order and manner as appropriate for the project

A UDP connection (that is not under ALG control) that is still active may now be prematurely destroyed provided that it is the least active connection and the project has determined that it is necessary because of resource issues.

A project soft-level of connection # restrictions is now possible. NAT asks the application for approval before a connection may be made - the app can use the previously listed feature to lower resource levels

A connection no longer has a TTL, rather there exists timer groups (each group having a specific TTL). Connections are placed in a timer group. This allows for precise timeout handling and fast determination of connections that may be reaped.

Various algorithmic and logic enhancements to improve performance

WISH:

A project soft-level of connection # restrictions is now possible.

Schedules:

Scheduling bugs related to start and end times crossing midnight has been fixed. Previously this bug would have allowed an ingressing rule (for the gateway firewall rules) to continue to function when it should have been switched off.

Gateway project (NAT related):

Now calls API’s of the ALG’s directly.

Classifiers of an API are always invoked for all new connections - thereby ensuring that irrespective of how or where a connection was made an ALG always gets a chance to process the payload if it is appropriate for that ALG

Project no longer creates static (NAT_BIND_STATIC) connections. Instead a new ‘virtual_server_instance’ structure has been created in gw_nat.c and the project code now handles virtual server entries outside of NAT - this is a move away from static nat connections (although some ALG’s still use them we are phasing them out).

Port forwarding and triggering now support ingress filters and schedules.

Gateway project (Routing related):

Work on multicast packets has been undertaken to better decide whether a multicast packet is allowed to ingress from the internet in gw_interfaces.c

IGMP router (lan side) always listens for igmp lan activity - showing memberships on the UI. However this membership information is only reported to the internet when an internet connection is available.

Gateway project (Security related):

Some invalid addresses have been checked and cause those packets to be discarded from the internet in gw_interfaces.c

Gw_upnp_igd.c was modified to ensure that a rogue upnp client on the lan cannot create a virtual server that allows packets to be bounced to the internet.


Notes on building SDK 7.10
--------------------------------------------------------------------------------


SMB is supported using server software licensed from Visuality. SDK 7.10 will ship without the SMB sources. Customers who want to build with this feature need to obtain separate license from Visuality before we can provide them with the modified source code. For details contact Ubicom's applciations engineer

To build with SMB or DMS a user should select these options under the applciation node of the ConfigTool to be included

Release notes for SDK 7.6 15-April-2008
--------------------------------------------------------------------------------

===================================================================

New set of technologies are being introduced in the 7.6 SDK release. Guest SSID, POSIX, New file system and MPPPoE are the main feature addition. The USB stack has been re-written to provide greater flexibility in supporting different classes of USB devices and to resolve outstanding performance and correctness issues. Brief description of the new features and other key details follow:


New Features introduced in 7.6:
--------------------------------------------------------------------------------
Multiple SSIDs: Up to 4 Virtual Access Points can be created each with a unique SSID and security settings. The router sample project uses this capability to implement Guest SSIDs that are isolated from the private SSIDs and each other. Up to 3 unique Guest SSIDs are supported. Guest SSID creation, deletion and status are managed through the router UI pages

POSIX Version 0.6: A new Package ipPOSIX introduced in 7.6 SDK implements a subset of Issue 6 of the POSIX Specification. ipPOSIX serves as the translation layer between "user space" and the kernel. It manages the processes, threads, the syscalls and memory protection. Above ipPOSIX, we have incorporated Newlib from RedHat as our standard library support

MPPPoE: Provides the user the ability to initiate multiple WAN PPPoE sessions. The WAN services supported on the single PPPoE session in past releases (NAT, DNS, Firewalls, etc.) are provided on these sessions. Up to 4 simultaneous PPPoE sessions can be created. Management of these sessions, creation, deletion, status is provided through the UI pages. This capability is provided for evaluation purposes only in 7.6 SDK.

File system: A new infrastructure (ipFS) has been added to the SDK. This infrastructure enables project code (and other packages) to access any number of underlying file systems in a common generic form. Specifically, ipFS supports the concept of mount and umounting one or more file systems and providing the interfaces for accessing those file systems. In SDK 7.6, we have implemented ipFATFS (a FAT file system implementation), ipFile (implements a flash file system), and ipRAMFS (that implements an in memory file system). Note: In SDK 7.6, ipFATFS does not support the older FAT12 based volumes.

Ralink Wireless: Support for Ralink 11n cards has been added

i18N per viewer When the product enables multiple languages, the web user interface is displayed in the language preferred by the viewer, as expressed via the language preference option in the web browser.

WDS: Added support for Wireless distribution System for Atheros and Ralink 11n wireless devices

WAN Widget: A yahoo Widget is added to the SKD to display near real-time WAN traffic usage in the form of bar graphs (uplink and downlink), displays WAN traffic statistics with a user settable threshold and alert (to watch for monthly transfer for instance), and monitor the WAN connection status.

Tools: In addition to these features, the tool chain (except for GCC) has been upgraded to GNU 4.x. Cygwin tools have been upgraded to version 1.5.24. The Ubicom SDK installer is modified to allow the user to install Ubicom cygwin build or skip it. Latest Cygwin and the latest GNU tool chain has been QA tested on Windows XP only, however some of our engineers have been using the updated tools successfully on Vista but QA on Vista of the updated tools is planned for a later release. A new IDE (Eclipse) has been included in 7.6 SDK for evaluation purposes.


Known issues/Limitations
--------------------------------------------------------------------------------

The configuration database for wireless projects was extended to support Multiple SSIDs. Configuration settings from projects built using earlier SDK versions cannot be used to restore settings on an SDK7.6 project

Eclipse can be used with any released SDK. However to use the debugger from within Eclipse, the latest tool chain will have to be installed. Latest tool chain is released as part of SDK 7.6 and later releases

In 7.6 MPPPoE implementation, a single instance of UPnP service is available for association with any of the active WAN sessions. Selection of which session to associate UPnP to is done through the UI. Only a single UPnP session is available at any one time no matter how many PPPoE sessions are active.

Connect on demand is not supported in MPPPoE in this release. This means sessions will not be started and stopped driven by WAN activity. Sessions will be created and stopped manually

A bug exists in MPPPoE that prevents secondary WAN connections to be established unless the internet session is up in always ON mode. This not a limitation on manual modes where each session can be started and stopped through the UI

--------------------------------------------------------------------------------

================================================================================
SDK 7.4.1 Highlights

This release fills out the capability introduced in SDK 7.4. Ubicom has tested
our reference gateway project against a number of standards and determined that
it is certifiable. There are a number of enhancements for manufacturability,
and new capability of a paired AP & Bridge set with instant secure connectivity.

Here is a list of new capabilities:

Radio on board
Radio calibration and testing is required when the radio circuit is
laid on the main board with the ip5k. This is now supported for both
Atheros and Ralink radios.

AP & Bridge enhancements
Using a special build method and boot loader, a product is enabled that
functions as either an Access Point or as a Bridge. The application uses
an autodetection method to determine if it should be an AP or Bridge.

AP & Bridge matched pair
A sample production line test (PLT) allows the programming of a matched
pair of AP and Bridge, so that when first powered up, they recognize
each other without user input.

Multi-cast support

Safari 3.0 browser support

New certifications
Wi-Fi Protected Setup (WPS)
Wi-Fi 11n for 2.4 GHz band (AP mode)

Release notes for SDK 7.4 16-April-2007
--------------------------------------------------------------------------------

================================================================================
SDK 7.4 Highlights

This release is the culmination of 6 months' effort following SDK 7.2.
We are proud of it's many new capabilities. Less obvious, but equally
important, this release has many subtle changes to increase performance
and reliablility.

Radio Devices
Atheros 11n and 11na radios are supported

Ralink 11n radios are supported

Statistics
Many packages are enhanced to provide a consistent API for reading
statistics. For example, ethernet statistics (ipEthernet, ipWDev) and
QoS (ipWISH, ipQosQueue) now provide statistics through a function call,
rather than requiring an application developer to read private header
files to find information.

The project gateway_ip3k is updated to use the new statistics
functionality. The file cgi_xmlstats.c is a good example of how to use
the statistics APIs.

A PC application, called a widget, has been provided. Refer to
gateway_ip3k\tools\widgets for an example. This widget is based around
the Yahoo widget framework. Widgets can be used with a desktop
environment to show router statistics in real time.

Managed VoIP router
A new reference board is provided. This board combines our previous
4-port wired LAN + PCI router with an alternative WAN through a DSL
device. It also equipped with circuitry for enabling two telephone
connections for VoIP operations. Contact Ubicom Marketing for details
about this board (refer to the "IAD Evaluation board").

In support of this platform, many new packages are supplied. Basic
VoIP functions are supported in ipVoice, ipSLICDev, and ipProSLIC.
These packages provide CODEC, Jitter Buffer, and SLIC support.

Our platform now also supports Remote Management, through the imple-
mentation of the TR-069 protocol (DSL Forum). In the gateway_ip3k
project, we've supported a cross-section of TR-098 parameters as an
example of how to use this package. We have also implemented TR-111,
which is used to help managed projects on the LAN side communicate with
a remote configuration server.

DSL support and VoIP connection (SIP, RTP) are not provided in this
release.

Tuned networking performance
The networking performance of ipOS on the IP5000 has been significantly
improved. The driver support for the Atheros and Ralink radios takes
advantage of the IP5000's improvements over the IP3000 to provide
excellent throughput and stability.

Wireless bridge project
SDK 7.4 is the first of the IP5000 series software releases to feature
our wireless bridge sample project, wbridge. This project is a fully
functional bridge, including enterprise-class authentication algorithms
like PEAP and EAP-TTLS. This project also incorporates our automated
QoS package, ipWISH, and the new, one-button configuration protocol,
WiFi Protected Setup (see ipWiFiSC).

The wireless bridge is an excellent starting place for creating appli-
cations that will be wireless endpoints on a network.

Better development platform
SDK 7.4 also adds several sample projects, starter, and telnet for
example. These projects are fully commented, and designed to be
useful for newcomers to our platform. The gateway_ip3k and wbridge
projects are great if you want everything, but these other projects
are helpful for the programmer looking to start with something simple.

Additionally, we've significantly improved our catalog of help text,
and even recorded some internal training discussions onto DVD for
the benefit of our users.

Upgraded tools
The master makefile and configtool have been updated to allow debug
messages to be enabled and disabled per-package. Most importantly,
the debug level can be set per-package, so that one package can be set
to "trace", while another package is only set to "warn". The debug
levels can be set during a debug session as well. The special note
below has some information about how to use this new capability.

dumpheap is a tool that reads a coredump file and analyzes memory
usage, looking for memory leaks. The tool is found in
tools/bin/win32. The SDK documentation contains instructions for using
this tool.

The profiler tool, ip3kprof is significantly enhanced to assist in the
analysis of application performance on the IP5000 family. Refer to the
SDK documentation for usage notes.

Many package upgrades and new packages
The package directory is bursting with new features. Existing pagkages
have been updated to provide better flexibility. Some highlights:

ipNetbuf
Now supports variable-length netbuffers, allowing up to
64 Kbytes to be stored in one netbuf
ipHeap
Supports cache-line alignment for higher performance
ipLock
New package replacing ipSpinlock
ipRateEstimator
Supports more ISPs, more accurately (for example SBC DSL)
ipEthernet

SPECIAL NOTE: Issue Not Resolved in Release
-------------------------------------------------------------------------------
Magic Number Checking -- Impacts packages released as binaries.
Magic Number checking is not enabled when "Global Debug -> Enable All
Assertions" is selected in ConfigTool. The greatest effect that this
has is on the use of packages released as binaries. Binary packages are
released with a debug, and a production image. All binary packages, and
the packages in their dependency tree, must be switched as a group
between production and debug.

The reason for this is twofold: First, if the subordinate packages have
"magic checking" enabled, then the size of their data structures is
different, with and without debug enabled. This is a problem for our
packages where the data structure is public. Second, where the sub-
ordinate packages have inlined functions that are non-inlined for
debugging. This also causes problems. If you are writing a new pack-
age, or upgrading an existing package to sdk 7.4, do not copy the
sdk 7.4 packages. Instead, use the following structure to wrap Magic
Number checking so that it is turned on when "Enable All Assertions"
is selected.

If the data structure is in a public header, then surround the
definition of the magic by:
struct mypkg_instance {
u32_t stuff;
char * morestuff;
#if defined(DEBUG) && (defined(<pkg_name>_DEBUG) || defined(DEBUG_ASSERT_ALL))
u32_t magic;
#endif
};

If the data structure is in a private header, this can be shortened:
struct mypkg_instance {
u32_t stuff;
char * morestuff;
#if defined(PKG_DEBUG) || defined(DEBUG_ASSERT_ALL))
u32_t magic;
#endif
};

All magic checking in private source files can be surrounded by:
mypkg_alloc_instance {
inst->stuff = 22;
#if defined(PKG_DEBUG) || defined(DEBUG_ASSERT_ALL))
inst->magic = MYPKG_MAGIC;
#endif
return inst;
}

The following packages are either released as binaries, or are in the
dependency tree of the binary packages: ipEthDev, ipHAL, ipHeap,
ipIPHeader, ipLibC, ipLMACDev, ipLock, ipLMACAR5212, ipLMACRALINK,
ipMACAddr, ipMembuf, ipMQueue, ipNAT, ipNATQoS, ipNetbuf, ipNetpage,
ipOneshot, ipOS, ipPCI, ipQoSQueue, ipRateEstimator, ipStack, ipStorage,
ipTCPHeader, ipThread, ipTimer, ipUDPHeader, ipWDev, ipWISH

Release notes for SDK 7.2.1 16-October-2006
-------------------------------------------------------------------------------

This release of the Ubicom SDK is significant because it provides updates
to the gateway_ip3k project that have been qualified by Microsoft as "Works with
Vista". This release also includes support for the very latest implementation
of WiFi Alliance's WiFi Protected Setup protocols.

In addition, there are several bug fixes, and the HTTPS handling code has been
updated to be more defensive against malicious attacks. There are some tool
upgrades as well.

If you are upgrading from an IP3k development system, please use the tools
with this distribution. They will work for building both IP3k and IP5k projects.


SDK 7.2.1 is a release of the software development kit for the Ubicom IP5000.

This release contains a number of advancements beyond the SDK 7.2 release:
o Tuning of 802.11n device drivers for higher performance and stability
o Tuned performance in QoS to match Microsoft WHQL tests
o Wireless Intelligent Stream Handling (WISH)
o WiFi Protected Setup (AP role only)
o Microsoft Link Layer Topology Discovery (LLTD) support

In addition, some package/build/tool issues were fixed:
o Fix a build issue where configuration files larger than 1 flash
sector are loaded incorrectly
o Fix an error in debugger interface where the call stack is
incorrectly calculated
o Introduce a new tool heap_dump, which can be used to trace memory
allocations in a coredump file
o ipTLS was partially rewritten to address memory leaks in the event
of malicious or otherwise failing connection attempts


Migrating from SDK 7.2 to SDK 7.2.1

There is only one API change, which is in ipTCP and ipTCPS:
Previously on receipt of a FIN from a remote host ipTCP and ipTCPS
would signal a close callback to the application layer, the TCP
layer would move the connection into a CLOSE-WAIT state and then the
connection would no longer accept data from the local application.
This behaviour didn't meet the requirements of RFC793 where the
local application should (optionally) be able to continue sending
data to the remote host until it too was ready to send a FIN.

The software now does not cause the receipt of a remote FIN to
automatically trigger the close behaviour locally. Instead the
application code must now explicitly close or reset the connection.
This allows the local application to also perform connection
assassinations where a RST is sent instead of a FIN.

The change does require that any TCP close callback function must
now either explicitly trigger close behaviour or may, optionally,
defer sending such a close until later. ipHTTP now supports this
optional deferred close in order to allow it to continue sending
data in response to a request that was immediately terminated with
a FIN.

As part of ongoing cleanup work within the SDK the close callback
was also modified to take an enum parameter for the closure reason
- this requires that all such callbacks be slightly modified and
provides a good reminder to add a call to tcp_connection_close()
for any situations where the original SDK behaviour is still required.

In addition to these the TCP error returns were changed from s8_t
to tcp_error_t enums as part of ongoing SDK cleanup work.


-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
Release notes for SDK 7.2 September 15-2006
-------------------------------------------------------------------------------

This sdk release builds on the first software release for the Ubicom IP5000
processor. There are some new featuers, and it includes a number of defect
fixes and performance improvements.

New in this release are:
o Ability to use a single switch chip for both LAN and WAN
o PPPoE passthrough mode
o TLS and SSL server functionality
o TLS client functionality


-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
Release notes for SDK 7.0 July 15-2006
-------------------------------------------------------------------------------
Ubicom SDK 7.0 is the first SDK release supporting the IP5000 line
of microprocessors. The goal of this release is to provide ease-
of-development features, both from software innovation, and new
hardware functions. In addition, this release continues to expand
on the strengths of ipOS, delivering low-latency network traffic with
a high quality, small executable footprint. This release supports the
802.11n (draft) radio from Atheros.

This release focusses on the Home Router reference platform, this
is the only sample project included. Other sample projects will
be provided in future releases.


-------------------------------------------------------------------------------
Release features
o Server Side Includes (SSI)
o Reflection
o Draft 11n radio support
o IP5000 hardware features (new to ip5000)
o Wireless Intelligent Stream Handling (WISH)
o WiFi Simple Config
o Link Layer Topology Discovery (LLTD)
o Home Network Administration Protocol (HNAP)
o String Internationalization (i18n)
o Advanced XML handling
o Simplified HTTP serving
o Secure Sockets (TLS 1.0)


-------------------------------------------------------------------------------
Server side includes (SSI) and Reflection

Server Side Includes (SSI) is a different technique for developing user
interfaces. Using SSI and Reflection, the UI writer can directly access
any system parameters for display or modification. SSI allows the user
interface to be developed using off-the-shelf web page tools. This
enhancement is part of Ubicom’s work to provide a solid platform for
development.

Note: The UIGEN method of development is deprecated for this release, in
favor of SSI.

Reflection is a system whereby run-time information about parameter names
and type information is available to the executable. This feature is used
by SSI for greatly simplified parameter access, and is used for other
functions, such as UPnP and TR-069 handling.


Draft 11n Radio Support

This release supports the latest draft 11n radio from Atheros. The IP5000
platform allows full exploitation of the available bandwidth, and reduces
the processor load, enabling advanced functionality. This feature is
released as a binary library only, except where the appropriate licenses
have been executed with Atheros.


-------------------------------------------------------------
New IP5000 hardware features

o PCI is included as a hardware block, and so takes less processor time
o There is an integrated cryptographic accelerator
o All memory is accessible through C pointers (no mem_* API needed)
o USB 2.0 is available


Wireless Intelligent Stream Handling (WISH)

WISH is the next step for the Ubicom Stream Engine technology. This
innovation applies automated classification for QoS between the wireless
local network and the wired connections. This software release includes
the first level of WISH implementation. At this level, streaming media
files that are served using HTTP are recognized and prioritized. This
feature is released as a binary library only.


-------------------------------------------------------------
Wi-Fi Simple Configuration

Simple Configuration is protocol specified by the WiFi Alliance, and
is designed to be an easy and secure method for adding clients to a
wireless network. This release supports the AP portion of the protocol.
A device enabled with this code can act in the "AP" role.


Link Layer Topology Discovery

This is a protocol from Microsoft that allows a client to discover all
of the elements of a local network, even through levels of home routers.
The protocol also can be used to configure some quality-of-service elements.
Installing this source code requires executing a license agreement with
Microsoft.


Home Netowrk Administration Protocol (HNAP)

This protocol, created by Pure Networks, provides a method for configuring
network equipment from a LAN-based PC.


-------------------------------------------------------------
String Internationalization (i18n)

The i18n functionality is updated in this release. The new system supports
the SSI and provides faster performance. In some usages, the language
presented can be changed on-the-fly, and based on the preferred language
of the attached web browser.


Advanced XML Handling

This release completes a sequence of enhancements that enable simple
handling of SOAP and other XML-based protocols. Both reading and writing
XML are well supported. The new packages ipSOAPWriter and ipSOAPParser
are introduced. The packages ipSOAPServer and ipSOAPClient are deprecated
in this release.


Simplified HTTP

Both HTTP serving and browsing are improved and simplified, with the
introduction of ipHTTP, ipWebServer and ipWebBrowser. Using these packages,
it is very easy to serve pages, or read external pages. ipHTTPClient
and ipWeb are deprecated in this release.


Secure Sockets Layer (TLS 1.0)

TLS authentication and stream encryption is supported. Certificates for
both client and server are supported. SSL 3.0 is supported for server-side
transactions only.
