Title: RMPP Message Format Errors

Hi Sean,   You wrote: "Note that the current implementation of the RMPP code ignores the payload length on the receive side, and instead relies on the last bit to determine the end of a transfer."   But the receive side needs to calculate back the correct size of the assembled MAD. If it is done in kernel or user it does not matter. To my best knowledge the only way to calculate how many records are enclosed in an RMPP message is to use the paylen and offset. How can it be done without looking at paylen ?   EZ   Eitan Zahavi Design Technology Director Mellanox Technologies LTD Tel:+972-4-9097208 Fax:+972-4-9593245 P.O.

I will not be able to look at this until early next week (with IDF running this week), but I will try to do so.   So, it wouldn't surprise me if the receive side accepted an invalid RMPP MAD. - Sean
