Greetings. Globus, a grid computing package, relies on an aspect of UDP that is seldom used. Specifically, a reply can come from anywhere on the planet, not just from the destination of the prompting packet.
Kernels <= 2.3.14 had a sysctl that factored out a UDP reply packet's source address/port before deciding whether or not to de-masquerade it. Now, I'm faced with the task of implementing a new cluster and find that this functionality has been removed. An examination of the latest kernels shows that both UDP and TCP packets are de-masqueraded in the same way. Further, I can find no patch-o-matic that re-introduces "loose" UDP de-masquerading. So, what are my options? I'm rather reluctant to move back to 2.3.14. Thanks.
