Pull crypto library updates from Eric Biggers: - Migrate more hash algorithms from the traditional crypto subsystem to lib/crypto/ Like the algorithms migrated earlier (e.g. SHA-*), this simplifies the implementations, improves performance, enables further simplifications in calling code, and solves various other issues: - AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC) - Support these algorithms in lib/crypto/ using the AES library and the existing arm64 assembly code - Reimplement the traditional crypto API's "cmac(aes)", "xcbc(aes)", and "cbcmac(aes)" on top of the library - Convert mac80211 to use the AES-CMAC library. Note: several other subsystems can use it too and will be converted later - Drop the broken, nonstandard, and likely unused support for "xcbc(aes)" with key lengths other than 128 bits - Enable optimizations by default - GHASH - Migrate the standalone GHASH code into lib/crypto/ - Integrate the GHASH code more closely with the very similar POLYVAL code, and improve the generic GHASH implementation to resist cache-timing attacks and use much less memory - Reimplement the AES-GCM library and the "gcm" crypto_aead template on top of the GHASH library. Remove "ghash" from the crypto_shash API, as it's no longer needed - Enable optimizations by default - SM3 - Migrate the kernel's existing SM3 code into lib/crypto/, and reimplement the traditional crypto API's "sm3" on top of it - I don't recommend using SM3, but this cleanup is worthwhile to organize the code the same way as other algorithms - Testing improvements: - Add a KUnit test suite for each of the new library APIs - Migrate the existing ChaCha20Poly1305 test to KUnit - Make the KUnit all_tests.config enable all crypto library tests - Move the test kconfig options to the Runtime Testing menu - Other updates to arch-optimized crypto code: - Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine - Remove some MD5 implementations that are no longer worth keeping - Drop big endian and voluntary preemption support from the arm64 code, as those configurations are no longer supported on arm64 - Make jitterentropy and samples/tsm-mr use the crypto library APIs * tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (66 commits) lib/crypto: arm64: Assume a little-endian kernel arm64: fpsimd: Remove obsolete cond_yield macro lib/crypto: arm64/sha3: Remove obsolete chunking logic lib/crypto: arm64/sha512: Remove obsolete chunking logic lib/crypto: arm64/sha256: Remove obsolete chunking logic lib/crypto: arm64/sha1: Remove obsolete chunking logic lib/crypto: arm64/poly1305: Remove obsolete chunking logic lib/crypto: arm64/gf128hash: Remove obsolete chunking logic lib/crypto: arm64/chacha: Remove obsolete chunking logic lib/crypto: arm64/aes: Remove obsolete chunking logic lib/crypto: Include instead of lib/crypto: aesgcm: Don't disable IRQs during AES block encryption lib/crypto: aescfb: Don't disable IRQs during AES block encryption lib/crypto: tests: Migrate ChaCha20Poly1305 self-test to KUnit lib/crypto: sparc: Drop optimized MD5 code lib/crypto: mips: Drop optimized MD5 code lib: Move crypto library tests to Runtime Testing menu crypto: sm3 - Remove 'struct sm3_state' crypto: sm3 - Remove the original "sm3_block_generic()" crypto: sm3 - Remove sm3_base.h ...

Add support for serializing zone writes at QD=1 for rotational zoned devices, yielding significant throughput improvements. - Add SED-OPAL ioctls for Single User Mode management and a STACK_RESET command. - Add io_uring passthrough (uring_cmd) support to the BSG layer. - Replace pp_buf in partition scanning with struct seq_buf. - zloop improvements and cleanups. - drbd genl cleanup, switching to pre_doit/post_doit. - NVMe pull request via Keith: - Fabrics authentication updates - Enhanced block queue limits support - Workqueue usage updates - A new write zeroes device quirk - Tagset cleanup fix for loop device - MD pull requests via Yu Kuai: - Fix raid5 soft lockup in retry_aligned_read() - Fix raid10 deadlock with check operation and nowait requests - Fix raid1 overlapping writes on writemostly disks - Fix sysfs deadlock on array_state=clear - Proactive RAID-5 parity building with llbitmap, with write_zeroes_unmap optimization for initial sync - Fix llbitmap barrier ordering, rdev skipping, and bitmap_ops version mismatch fallback - Fix bcache use-after-free and uninitialized closure - Validate raid5 journal metadata payload size - Various cleanups - Various other fixes, improvements, and cleanups * tag 'for-7.1/block-20260411' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (146 commits) ublk: fix tautological comparison warning in ublk_ctrl_reg_buf scsi: bsg: fix buffer overflow in scsi_bsg_uring_cmd() block: refactor blkdev_zone_mgmt_ioctl MAINTAINERS: update ublk driver maintainer email Documentation: ublk: address review comments for SHMEM_ZC docs ublk: allow buffer registration before device is started ublk: replace xarray with IDA for shmem buffer index allocation ublk: simplify PFN range loop in __ublk_ctrl_reg_buf ublk: verify all pages in multi-page bvec fall within registered range ublk: widen ublk_shmem_buf_reg.len to __u64 for 4GB buffer support xfs: use bio_await in xfs_zone_gc_reset_sync block: add a bio_submit_or_kill helper block: factor out a bio_await helper block: unify the synchronous bi_end_io callbacks xfs: fix number of GC bvecs selftests/ublk: add read-only buffer registration test selftests/ublk: add filesystem fio verify test for shmem_zc selftests/ublk: add hugetlbfs shmem_zc test for loop target selftests/ublk: add shared memory zero-copy test selftests/ublk: add UBLK_F_SHMEM_ZC support for loop target ...

crypto: geniv - Remove unused spinlock from struct aead_geniv_ctx

The spin lock in geniv hasn't been used in over 10 years. Remove it. Signed-off-by: Herbert Xu

crypto: rng - Make crypto_stdrng_get_bytes() use normal RNG in non-FIPS mode

2026-04-03T00:56:12+00:00

"stdrng" is needed only in "FIPS mode". Therefore, make crypto_stdrng_get_bytes() delegate to either the normal Linux RNG or to "stdrng", depending on the current mode. This will eliminate the need to built the SP800-90A DRBG and its dependencies into CRYPTO_FIPS=n kernels. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: rng - Unexport "default RNG" symbols

2026-04-03T00:56:12+00:00

Now that crypto_default_rng, crypto_get_default_rng(), and crypto_put_default_rng() have no users outside crypto/rng.c itself, unexport them and make them static. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: rng - Add crypto_stdrng_get_bytes()

2026-04-03T00:56:11+00:00

All callers of crypto_get_default_rng() use the following sequence: crypto_get_default_rng() crypto_rng_get_bytes(crypto_default_rng, ...) crypto_put_default_rng() While it may have been intended that callers amortize the cost of getting and putting the "default RNG" (i.e. "stdrng") over multiple calls, in practice that optimization is never used. The callers just want a function that gets random bytes from the "stdrng". Therefore, add such a function: crypto_stdrng_get_bytes(). Importantly, this decouples the callers from the crypto_rng API. That allows a later commit to make this function simply call get_random_bytes_wait() unless the kernel is in "FIPS mode". Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

lib/crypto: arm64/aes: Remove obsolete chunking logic

2026-04-01T20:02:09+00:00

Since commit aefbab8e77eb ("arm64: fpsimd: Preserve/restore kernel mode NEON at context switch"), kernel-mode NEON sections have been preemptible on arm64. And since commit 7dadeaa6e851 ("sched: Further restrict the preemption modes"), voluntary preemption is no longer supported on arm64 either. Therefore, there's no longer any need to limit the length of kernel-mode NEON sections on arm64. Simplify the AES-CBC-MAC code accordingly.

crypto: algif_aead - Revert to operating out-of-place

2026-03-31T08:11:47+00:00

This mostly reverts commit 72548b093ee3 except for the copying of the associated data. There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.

lib/crypto: tests: Migrate ChaCha20Poly1305 self-test to KUnit

2026-03-30T19:35:30+00:00

Move the ChaCha20Poly1305 test from an ad-hoc self-test to a KUnit test. Keep the same test logic for now, just translated to KUnit. Moving to KUnit has multiple benefits, such as: - Consistency with the rest of the lib/crypto/ tests. - Kernel developers familiar with KUnit, which is used kernel-wide, can quickly understand the test and how to enable and run it. - The test will be automatically run by anyone using lib/crypto/.kunitconfig or KUnit's all_tests.config. - Results are reported using the standard KUnit mechanism. - It eliminates one of the few remaining back-references to crypto/ from lib/crypto/, specifically a reference to CONFIG_CRYPTO_SELFTESTS.
