It also includes the fscrypt branch which is needed for ubifs encryption work as well as ext4 encryption and fscrypt cleanups. Lots of cleanups and bug fixes, especially making sure ext4 is robust against maliciously corrupted file systems --- especially maliciously corrupted xattr blocks and a maliciously corrupted superblock. Also fix ext4 support for 64k block sizes so it works well on ppcle. Fixed mbcache so we don't miss some common xattr blocks that can be merged" * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (86 commits) dax: Fix sleep in atomic contex in grab_mapping_entry() fscrypt: Rename FS_WRITE_PATH_FL to FS_CTX_HAS_BOUNCE_BUFFER_FL fscrypt: Delay bounce page pool allocation until needed fscrypt: Cleanup page locking requirements for fscrypt_{decrypt,encrypt}_page() fscrypt: Cleanup fscrypt_{decrypt,encrypt}_page() fscrypt: Never allocate fscrypt_ctx on in-place encryption fscrypt: Use correct index in decrypt path. fscrypt: move the policy flags and encryption mode definitions to uapi header fscrypt: move non-public structures and constants to fscrypt_private.h fscrypt: unexport fscrypt_initialize() fscrypt: rename get_crypt_info() to fscrypt_get_crypt_info() fscrypto: move ioctl processing more fully into common code fscrypto: remove unneeded Kconfig dependencies MAINTAINERS: fscrypto: recommend linux-fsdevel for fscrypto patches ext4: do not perform data journaling when data is encrypted ext4: return -ENOMEM instead of success ext4: reject inodes with negative size ext4: remove another test in ext4_alloc_file_blocks() Documentation: fix description of ext4's block_validity mount option ext4: fix checks for data=ordered and journal_async_commit options ... 2016-11-14T01:18:16+00:00 David Gstir david@sigma-star.at 2016-11-13T21:20:48+00:00 urn:sha1:9c4bb8a3a9b4de21753053d667310c2b7cb39916 Avoid re-use of page index as tweak for AES-XTS when multiple parts of same page are encrypted. This will happen on multiple (partial) calls of fscrypt_encrypt_page on same page. page->index is only valid for writeback pages.

Use this helper function from filesystems instead of the original unmap_underlying_metadata() to save some boiler plate code and also have a better name for the functionalily since it is not unmapping anything for a *long* time.
