[rds-devel] FW: RDS -- how to detect peer is gone ?

[Tang, Changqing]

If I use 32b unmodified, rds message without control message works, but if I use control
Message, it does not work. I even print msg_controllen from kernel function rds_sendmsg(), it does not match what I passed in in my 32bit user app code.

Idea ?

    Because you are using a 64b interface with a 32b application.
    Try 32b unmodified.
