Hi, I have been trying to build a protocol similar to TCP within the Linux kernel for a mobile computing environment. For that, I need to look at the list of unacknowledged sk_buffs in order to change their headers so that I can send them through a new interface. I have tried sk->send_head, sk->send_tail but without any success. In spite of there being around 36-37 unacknowledged segments, there is still nothing which I get by following the next or prev pointers of send_head and send_tail. Can anyone help me tell which other place I can look into ? Any help will be greatly appreciated. If you can also cc the reply to vsgupta@cs.uiuc.edu, then that would be great. Thanks a lot, Vijay
