Clever attack exploits fully-patched Linux kernel

This isn't a bug in the Linux kernel - it's a bug in GCC, specifically in the optimization routines. Turn that optimization off, recompile, no bug.

A recently published attack exploiting newer versions of the Linux kernel is getting plenty of notice because it works even when security enhancements are running and the bug is virtually impossible to detect in source code reviews.

Notes: If you put a <mailto:> link in the URL field your address will not be mangled: this could be a bad idea as your email address could be easily harvested by bots designed for SPAM. The comments field should now format correctly for line feeds and carriage returns: when you hit the 'Enter' or 'Return' keys in your comment it should break to a new line. The text should wrap cleanly. Please let me know if it doesn't. No HTML tags will pass through - entering links seems to be the main cause of comment SPAM. Also, please be sure that Javascript is enabled in your browser before attempting to post a writeback. Sorry for any inconvenience, but this really helps cut down on the amount of comment SPAM I have to deal with.
