From: Greg KH <gre...@linuxfoundation.org> 3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Andy Lutomirski <l...@amacapital.net> commit 9ab4233dd08036fe34a89c7dc6f47a8bf2eb29eb upstream. Otherwise the code races with munmap (causing a use-after-free of the vma) or with close (causing a use-after-free of the struct file). The bug was introduced by commit 90ed52ebe481 ("[PATCH] holepunch: fix mmap_sem i_mutex deadlock") [bwh: Backported to 3.2: - Adjust context - madvise_remove() calls vmtruncate_range(), not do_fallocate()] [luto: Backported to 3.0: Adjust context] -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
