"Reasoning Inc. announced that it is making available a study
that reports that the TCP/IP protocol stack implementation in
version 2.4.19 of the open source Linux kernel has fewer defects
than the TCP/IP protocol stacks of several commercial equivalents.
The study by Reasoning is the first published comparison of code
defect assessment of an open source software application versus
equivalent commercial software applications.
"Reasoning's study compared six implementations of TCP/IP, the
fundamental protocols underlying the Internet. Besides the Linux
kernel, three of the implementations were part of commercial
general-purpose operating systems, and two were embedded in
commercial telecommunications equipment. Reasoning found 8 defects
in 81,852 lines of Linux kernel source code - the fewest number of
defects of the various implementations of TCP/IP inspected by
Reasoning as part of its study..."
