Linux's Security Through Obscurity

An anonymous reader writes "The age-old full disclosure debate has been raging again, this time in no other place than at the foundations of the open-source flagship GNU/Linux operating system: within the Linux kernel itself. It beggars belief, but even Linux creator, Linus Torvalds, has advocated against the sort of openness on which Linux has thrived, arguing that security fixes to the kernel should be obscured in changelogs, saying 'If it's not a very public security issue already, I don't want a simple "git log + grep" to help find it.' Unfortunately, it's not kernel exploit writers who need to grep the changelog in order to find kernel vulnerabilities. On the contrary, it's downstream distributors who rely on changelog information in order to decide when to patch the kernels of their distributions, in order to keep their users safe."

He doesn't want them to stand out in any way at all.

Ant tyat is where he does not get it. They have to stand out, clearly and easy to find. Anything else helps the attackers more than the defenders. Linus unfortunately has not a clue about this.
