It's accurate, and I asked them repeatedly about the nature of the bug and the fix and they wouldn't tell me. I'm drafting a blog post about it but was hoping to provide more detail for the reader other than "Oracle said so". My take was that Oracle said they re-wrote the module from scratch, and so wasn't bound by any GPL-type of license forcing them to make their changes available.

It was disappointing to say the least, and so long story short we had to abandon Infiniband in favor of 10gbE.
