As usual, all these patches have been in linux-next with no reported issues, and I've tested them with xfstests. ---------------------------------------------------------------- Eric Biggers (16): fscrypt: remove kernel-internal constants from UAPI header fscrypt: add fscrypt_is_nokey_name() ext4: prevent creating duplicate encrypted filenames f2fs: prevent creating duplicate encrypted filenames ubifs: prevent creating duplicate encrypted filenames fscrypt: remove unnecessary calls to fscrypt_require_key() fscrypt: simplify master key locking ext4: remove ext4_dir_open() f2fs: remove f2fs_dir_open() ubifs: remove ubifs_dir_open() ext4: don't call fscrypt_get_encryption_info() from dx_show_leaf() fscrypt: introduce fscrypt_prepare_readdir() fscrypt: move body of fscrypt_prepare_setattr() out-of-line fscrypt: move fscrypt_require_key() to fscrypt_private.h fscrypt: unexport fscrypt_get_encryption_info() fscrypt: allow deleting files with unsupported encryption policy fs/crypto/fname.c | 8 +++- fs/crypto/fscrypt_private.h | 56 +++++++++++++++------- fs/crypto/hooks.c | 55 +++++++++++---------- fs/crypto/keyring.c | 10 +--- fs/crypto/keysetup.c | 44 +++++++++++------ fs/crypto/policy.c | 27 +++++++---- fs/ext4/dir.c | 16 ++----- fs/ext4/namei.c | 13 ++--- fs/f2fs/dir.c | 10 +--- fs/f2fs/f2fs.h | 2 + fs/ubifs/dir.c | 28 +++++------ include/linux/fscrypt.h | 112 ++++++++++++++++++++++++++++--------------- include/uapi/linux/fscrypt.h | 5 +- 13 files changed, 227 insertions(+), 159 deletions(-)
