As part of my project, while reading the reports, I came to know about bugs where incorrect sizeof expressions are used, typically leading to allocation of data of the wrong size.  There were many in the versions 2.4.x and 2.6.x. I was also required to list FPs (false positives) by Coccinelle. This post will be about, what I found for the mentioned case.
