First the article is a couple of weeks old. Second, the claim that no distribution (except maybe Mandriva) has issued new, patched kernels is false by now. VectorLinux had one out shortly after this article came out, for example. Lots of distros have patched this.

My point is why post this outdated article now? It generates FUD not because the content was wrong but because it appears it is current when it is not.

Because it's the publicly available version, which (as you noted) is now almost two weeks old. The latest version isn't available to non-subscribers.

Quoting:Why post this outdated article now?


Because it's from LWN. It contains a wealth of technical information and explanation missing from other articles. Also, because it's from LWN we could not post it earlier. LWN articles only become publicly available after a few weeks.

Exactly Sander, I caught hell for posting them before they were supposed to be publicly available so I quit doing it. I wait until the are publicly available before posting them to our newswire, which means they are a minimum of two weeks old at that point.

Then don't post them.

If the best we can do is post outdated material from LWN, and they don't like it when we post current material. Don't post any material.

@TracyAnne: I don't know about you, but I love the high technical level of LWN articles. They always contain deep technical know-how and background that other articles simply don't have. There's no way that InfoWeek or some other IT news site is going to explain how the null pointer dereference works, why userspace programs can map memory to the low address space and how SE Linux fits in that picture. That's the reason I post such articles.

then I guess we put up with outdated articles.

Methinks there be a confusion of "outdated" and "irrelevant".

The case study of this particular bug is forever relevant.

That link is for only publicly available links as of now. I do not see that changing anytime soon.

Simple solution, put a warning label on LWN material. Something like "LWN Archive Article".

tuxchick: It's not whining. The information is sufficiently out of date to give a false impression about the state of the Linux kernel. It gives the idea that there are serious unsolved problems. It just isn't true at this point.

Quoting:It gives the idea that there are serious unsolved problems.
Being careful with pointers in C is an ongoing battle. The Linux kernel is no exception, as shown by two major bugs of this type in less than a month. As new devices require new drivers, and new developers hone their craft, the vigilance against uninitialized pointers must become habit. Just because these two bugs are resolved in the mainline, doesn't mean there are no more, nor that there will never again be another unresolved pointer in the Linux kernel.

This article should be a standard hand-out on Day 1 of pointer discussion. Like I said, outdated (w.r.t. the current mainline Linux kernel), but forever relevant.
