This is a poor patch that was never sent to the netdev list for review. Copies to and from user space should always check for buffer overruns. A better patch was submitted (attached) some time ago. Miller's patch has 2 flaws: 1) It accidentally removed a comment line that describes the purpose of the following memcpy(), paralleling language in the internet-draft. 2) It fails to test for buffer overruns. The existing code has an accurate test, that compiles (to no code) correctly with current gcc. But it produces a warning in some (fairly old) gcc versions. Instead, the better patch uses the Kernel defined BUILD_BUG_ON(). Please substitute the better patch in the main tree. > Merge branch 'master' of git://git.kernel.org/.../linville/wireless-2.6 > Merge branch 'master' of /home/davem/src/GIT/linux-2.6/ >
