Hello, I have a userspace app which does some mangling on packets in the userspace QUEUE target under 2.4.x. It relies on conntrack being loaded to defragment packets (it is in the POSTROUTING,mangle table). Works dandy under 2.4.x. I loaded up a Fedora RC2 machine (2.6.5 maybe?) to see how well it would work and for most packets it was fine. I was losing large packets, however (ie: 24K UDP packets). After some investigation and putting some checksum code in place, it looks like the packet's contents were getting corrupted by comparing checksums on the sender QUEUE and the receiver's QUEUE userspace apps. I am still checking on when this occurs, but when using 24K, the last bits of the defragmented packet were all '0's instead of the original value. I believe that if I do not alter the packet, that there are no issues (need to confirm today). I will be continuing tests today, but are there any known issues when altering large packets in userspace under the 2.6 kernel? Thanks in advance!! -Scott __________________________________ Do you Yahoo!? Yahoo! Mail is new and improved - Check it out! http://promotions.yahoo.com/new_mail
