Please include commit 90481622d7 ("hugepages: fix use after free bug
in "quota" handling") from Linus' tree in the next 3.3 stable release.
It applies without fuzz, though with offsets.It fixes a use-after-free bug in the huge page code that we are hitting when using KVM on IBM Power machines with large pages backing the guests, though it can in principle be hit in other ways also. Since it's a use-after-free bug, it tends to result in an immediate kernel crash if you have slab debug turned on, or occasional hard-to-debug memory corruption if you don't. The bug is also present in earlier kernels, and the patch should apply at least to 3.2. It would be good if it can be applied to earlier kernels also. Thanks, Paul. -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
