Patch "x86/build/64: Force the linker to use 2MB page size" has been added to the 4.9-stable tree

This is a note to let you know that I've just added the patch titled x86/build/64: Force the linker to use 2MB page size to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: x86-build-64-force-the-linker-to-use-2mb-page-size.patch and it can be found in the queue-4.9 subdirectory.

Lu" <hjl.tools(a)gmail.com> Date: Mon, 19 Mar 2018 13:57:46 -0700 Subject: x86/build/64: Force the linker to use 2MB page size From: H.J. Lu <hjl.tools(a)gmail.com> commit e3d03598e8ae7d195af5d3d049596dec336f569f upstream. Binutils 2.31 will enable -z separate-code by default for x86 to avoid mixing code pages with data to improve cache performance as well as security. To reduce x86-64 executable and shared object sizes, the maximum page size is reduced from 2MB to 4KB. But x86-64 kernel must be aligned to 2MB. Pass -z max-page-size=0x200000 to linker to force 2MB page size regardless of the default page size used by linker. Tested with Linux kernel 4.15.6 on x86-64. Signed-off-by: H.J.

[PATCH] ext4: fail ext4_iget for root directory if unallocated

by Theodore Ts'o

If the root directory has an i_links_count of zero, then when the file system is mounted, then when ext4_fill_super() notices the problem and tries to call iput() the root directory in the error return path, ext4_evict_inode() will try to free the inode on disk, before all of the file system structures are set up, and this will result in an OOPS caused by a NULL pointer dereference. https://bugzilla.kernel.org/show_bug.cgi?id=199179 Reported-by: Wen Xu <wen.xu(a)gatech.edu> Signed-off-… [View More]
