ext4 crypto: migrate into vfs's crypto engine

2016-07-10T18:01:03Z

This patch removes the most parts of internal crypto codes. And then, it modifies and adds some ext4-specific crypt codes to use the generic facility. Signed-off-by: Jaegeuk Kim Signed-off-by: Theodore Ts'o

Pull ext4 updates from Ted Ts'o: "Add support for the CSUM_SEED feature which will allow future userspace utilities to change the file system's UUID without rewriting all of the file system metadata. A number of miscellaneous fixes, the most significant of which are in the ext4 encryption support. Anyone wishing to use the encryption feature should backport all of the ext4 crypto patches up to 4.4 to get fixes to a memory leak and file system corruption bug. There are also cleanups in ext4's feature test macros and in ext4's sysfs support code" * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (26 commits) fs/ext4: remove unnecessary new_valid_dev check ext4: fix abs() usage in ext4_mb_check_group_pa ext4: do not allow journal_opts for fs w/o journal ext4: explicit mount options parsing cleanup ext4, jbd2: ensure entering into panic after recording an error in superblock [PATCH] fix calculation of meta_bg descriptor backups ext4: fix potential use after free in __ext4_journal_stop jbd2: fix checkpoint list cleanup ext4: fix xfstest generic/269 double revoked buffer bug with bigalloc ext4: make the bitmap read routines return real error codes jbd2: clean up feature test macros with predicate functions ext4: clean up feature test macros with predicate functions ext4: call out CRC and corruption errors with specific error codes ext4: store checksum seed in superblock ext4: reserve code points for the project quota feature ext4: promote ext4 over ext2 in the default probe order jbd2: gate checksum calculations on crc driver presence, not sb flags ext4: use private version of page_zero_new_buffers() for data=journal mode ext4 crypto: fix bugs in ext4_encrypted_zeroout() ext4 crypto: replace some BUG_ON()'s with error checks ...

KEYS: Merge the type-specific data with the payload data

2015-10-21T14:18:36Z

Merge the type-specific data with the payload data into one four-word chunk as it seems pointless to keep them separate. Use user_key_payload() for accessing the payloads of overloaded user-defined keys.

ext4 crypto: exit cleanly if ext4_derive_key_aes() fails

2015-07-22T04:08:08Z

Return value of ext4_derive_key_aes() is stored but not used. Add test to exit cleanly if ext4_derive_key_aes() fail. Also fix coverity CID 1309760. Signed-off-by: Laurent Navet Signed-off-by: Theodore Ts'o

ext4 crypto: use per-inode tfm structure

2015-05-31T17:34:22Z

As suggested by Herbert Xu, we shouldn't allocate a new tfm each time we read or write a page. Instead we can use a single tfm hanging off the inode's crypt_info structure for all of our encryption needs for that inode, since the tfm can be used by multiple crypto requests in parallel. Also use cmpxchg() to avoid races that could result in crypt_info structure getting doubly allocated or doubly freed. Signed-off-by: Theodore Ts'o

ext4 crypto: get rid of ci_mode from struct ext4_crypt_info

2015-05-18T17:20:47Z

The ci_mode field was superfluous, and getting rid of it gets rid of an unused hole in the structure. Signed-off-by: Theodore Ts'o
