Cisco admits iPhone license violation

Storm over Linux-based handset

Cisco plans to resolve a licence compliance issue regarding the use of Linux in one of its iPhones, the company wrote in a blog posting, but a researcher contends that Cisco has more work to do.

Cisco is working on fixing one problem in the WIP300 iPhone model, John Earnhardt, senior manager of global media operations for Cisco, wrote on Cisco's news blog on Saturday.

He said that Cisco has also investigated other issues that an open-source software researcher raised, but has verified that the phone complies with its licensing agreement except for the one issue.

Last week, Armijn Hemel, an open-source enthusiast and consultant with Loohuis Consulting, revealed that he'd reverse engineered Cisco's iPhone WIP300 and found that Cisco hasn't properly shared code used in the phone. The phone runs Linux and Cisco licensed the operating system under the GNU General Public License (GPL), requiring it to share the source code for changes to the operating system that it distributes.

Hemel spoke with Cisco in October, alerting the company to the omissions, he said. He first began publicly talking about the licensing violation last week.

When he first talked to Cisco, he didn't identify the exact code that hadn't been shared but late last week he sent the networking giant a technical report pointing out the relevant code. He contends that the phone has more than one issue and that he will watch for updates from Cisco. The company hasn't yet posted any changes or additions to the code it has already shared, he said.

The relevant code doesn't enable any type of radically interesting technology, Hemel said, so it's possible that Cisco, like many other companies and individuals, simply failed to notice that it hadn't shared the code. Sifting through code to ensure that it's properly shared can be a tedious and expensive proposition, Hemel said.

The incident points to larger issues in the open-source community. Many GPL licensees fail to appropriately adhere to the terms of the agreement, sometimes simply because they haven't implemented internal policies to ensure that they properly document and share their innovations, said Shane Coughlan, Freedom Task Force coordinator for the Free Software Foundation Europe, during an interview last week. One voluntary organisation, the GPL Violations Project, for which Hemel works, has successfully enforced 100 licence violations, both in and out of court.
