Hi, Please pull this usercopy fix for v4.18-rc8. Bart Massey discovered that the usercopy whitelist for JFS was incomplete: the inline inode data may intentionally "overflow" into the neighboring "extended area", so the size of the whitelist needed to be raised to include the neighboring field. Thanks! -Kees The following changes since commit 7daf201d7fe8334e2d2364d4e8ed3394ec9af819: Linux 4.18-rc2 (2018-06-24 20:54:29 +0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/usercopy-fix-v4.18-rc8 for you to fetch changes up to 961b33c244e5ba1543ae26270a1ba29f29c2db83: jfs: Fix usercopy whitelist for inline inode data (2018-08-04 07:53:46 -0700) ---------------------------------------------------------------- - Fix JFS usercopy whitelist (it needed to cover neighboring field too) for "overflow" inline inode data. ---------------------------------------------------------------- Kees Cook (1): jfs: Fix usercopy whitelist for inline inode data fs/jfs/jfs_dinode.h | 7 +++++++ fs/jfs/jfs_incore.h | 1 + fs/jfs/super.c | 3 +-- 3 files changed, 9 insertions(+), 2 deletions(-) -- Kees Cook Pixel Security
