It seems to me that RANDOM_IP_ID might be better as a sysctl rather than a kernel option. Would anyone mind if I changed this?
David.
I'd rather see a sysctl that switched between incremental frag IDs and arc4random() based IDs, followed by the removal of RANDOM_IP_ID.
For more info, see:

(I think we're still using the old code that's collision prone.)
Given that we're in a 16-bit space anyway, it's simpler to just use arc4random and stop pretending that we can avoid collisions.
Remember: An IP ID collision is equivalent to a packet being lost; this is not a big deal.
