The following changes since commit e04c78d86a9699d136910cfc0bdcf01087e3267e: Linux 6.16-rc2 (2025-06-15 13:49:41 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/fs/fscrypt/linux.git tags/fscrypt-for-linus for you to fetch changes up to fa65058063cbaba6e519b5291a7e2e9e0fa24ae3: ceph: Remove gfp_t argument from ceph_fscrypt_encrypt_*() (2025-07-10 12:33:17 -0700) ---------------------------------------------------------------- Simplify how fscrypt uses the crypto API, resulting in some significant performance improvements: - Drop the incomplete and problematic support for asynchronous algorithms. These drivers are bug-prone, and it turns out they are actually much slower than the CPU-based code as well. - Allocate crypto requests on the stack instead of the heap. This improves encryption and decryption performance, especially for filenames. It also eliminates a point of failure during I/O. ---------------------------------------------------------------- Eric Biggers (9): fscrypt: Explicitly include <linux/export.h> fscrypt: Drop obsolete recommendation to enable optimized SHA-512 fscrypt: Don't use problematic non-inline crypto engines fscrypt: Don't use asynchronous CryptoAPI algorithms fscrypt: Drop FORBID_WEAK_KEYS flag for AES-ECB fscrypt: Switch to sync_skcipher and on-stack requests fscrypt: Remove gfp_t argument from fscrypt_crypt_data_unit() fscrypt: Remove gfp_t argument from fscrypt_encrypt_block_inplace() ceph: Remove gfp_t argument from ceph_fscrypt_encrypt_*() Documentation/filesystems/fscrypt.rst | 45 ++++++++--------------- fs/ceph/crypto.c | 13 +++---- fs/ceph/crypto.h | 10 ++--- fs/ceph/file.c | 3 +- fs/ceph/inode.c | 3 +- fs/crypto/bio.c | 9 +++-- fs/crypto/crypto.c | 52 ++++++++++---------------- fs/crypto/fname.c | 69 +++++++++++++---------------------- fs/crypto/fscrypt_private.h | 23 ++++++++++-- fs/crypto/hkdf.c | 4 +- fs/crypto/hooks.c | 2 + fs/crypto/inline_crypt.c | 1 + fs/crypto/keyring.c | 5 ++- fs/crypto/keysetup.c | 23 +++++++----- fs/crypto/keysetup_v1.c | 55 ++++++++++++---------------- fs/crypto/policy.c | 4 +- fs/ubifs/crypto.c | 2 +- include/linux/fscrypt.h | 5 +-- 18 files changed, 146 insertions(+), 182 deletions(-)
