Subject: loopback interface - why checksum on header?
Date: Sat, 23 Jul 2011 18:30:18 +0200 [thread overview]
Message-ID: <4E2AF71A.6080703@inria.fr> (raw)
Hello everybody
I am wondering why the checksum of packets sent through the loopback
interface is computed on the header only.
If I understand correctly, it is assumed that a message cannot be
corrupted in RAM, thus there is no need to verify the integrity of the
whole message.
However, in that case, there is also no need to compute it on the header.
Consequently, why is it not the case?
Thank you in advance
