This patchset adds an ioctl FS_IOC_GET_ENCRYPTION_NONCE which retrieves the nonce from an encrypted file or directory. This is useful for automated ciphertext verification testing. See patch #1 for more details. Eric Biggers (4): fscrypt: add FS_IOC_GET_ENCRYPTION_NONCE ioctl ext4: wire up FS_IOC_GET_ENCRYPTION_NONCE f2fs: wire up FS_IOC_GET_ENCRYPTION_NONCE ubifs: wire up FS_IOC_GET_ENCRYPTION_NONCE Documentation/filesystems/fscrypt.rst | 11 +++++++++++ fs/crypto/fscrypt_private.h | 20 ++++++++++++++++++++ fs/crypto/keysetup.c | 16 ++-------------- fs/crypto/policy.c | 21 ++++++++++++++++++++- fs/ext4/ioctl.c | 6 ++++++ fs/f2fs/file.c | 11 +++++++++++ fs/ubifs/ioctl.c | 4 ++++ include/linux/fscrypt.h | 6 ++++++ include/uapi/linux/fscrypt.h | 1 + 9 files changed, 81 insertions(+), 15 deletions(-) base-commit: 98d54f81e36ba3bf92172791eba5ca5bd813989b -- 2.25.1
