b73abee375f1c3e3d4e5ea9c0cf99a918d8fc9ef - lib: Move SipHash into lib/crypto/

Sat, 03 Oct 2026 18:28:27 +0200

lib: Move SipHash into lib/crypto/The addition of SipHash to lib/ predated the existence of thelib/crypto/ directory. Since SipHash is a cryptographic algorithm, moveit from the top-level lib/ directory to lib/crypto/.(This does mean HalfSipHash comes with it too, as it's in the samefiles. But lib/crypto/ still seems like the proper place for both.)Specifically:- Move both siphash.c and siphash_kunit.c. Keep the header as-is for now.- Drop the dedicated MAINTAINERS entry for SipHash, as per the suggestion from Jason (https://lore.kernel.org/r/asB7QVFMlgKgbje2@zx2c4.com/). The C files now just fold up to the "CRYPTO LIBRARY" entry. Add the header explicitly, as it otherwise would be left unmaintained.- Move the kconfig option that controls the KUnit test. Put "CRYPTO_LIB" in its name and update the prompt and help text to make it consistent with the other crypto library test options.- Enable the KUnit test in lib/crypto/.kunitconfig.- Link to siphash.rst from the appropriate place in libcrypto-hash.rst.- Use obj-y instead of lib-y, for consistency with the fact that currently lib/crypto/ doesn't use kbuild's support for library file goals. We could keep it as lib-y, but virtually every kernel needs SipHash support anyway (with vsprintf, printk, IPv4, IPv6, etc. depending on it) so there is no practical difference in this case.Acked-by: Ard Biesheuvel Acked-by: Jason A.

Mon, 03 Aug 2026 01:30:05 +0200

lib/crypto: tests: Add KUnit test suite for AES-GCMAdd a KUnit test suite for the AES-GCM library API.It consists of:- All the shared test cases from aead-test-template.h. These include extensive consistency tests, a "Monte-Carlo test", and a benchmark.- Tests against hardcoded AES-GCM test vectors from external sources.Reviewed-by: Ard Biesheuvel Link: https://patch.msgid.link/20260802233005.161467-6-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/.kunitconfig

Fri, 27 Mar 2026 23:42:29 +0100

lib/crypto: tests: Migrate ChaCha20Poly1305 self-test to KUnitMove 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.Acked-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20260327224229.137532-1-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/.kunitconfig

lib/crypto: tests: Add KUnit tests for SM3Add a KUnit test suite for the SM3 library. It closely mirrors the testsuites for the other cryptographic hash functions. The actual test andbenchmark logic is already in hash-test-template.h; this just wires itup for SM3 in the usual way.Acked-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20260321040935.410034-6-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/.kunitconfig

ed1767442d919f57aaf83d69c33853da2644d902 - lib/crypto: tests: Introduce CRYPTO_LIB_ENABLE_ALL_FOR_KUNIT

Sat, 14 Mar 2026 04:59:26 +0100

lib/crypto: tests: Introduce CRYPTO_LIB_ENABLE_ALL_FOR_KUNITFor kunit.py to run all the crypto library tests when passed the--alltests option, tools/testing/kunit/configs/all_tests.config needs toenable options that satisfy the test dependencies.This is the same as what lib/crypto/.kunitconfig already does.However, the strategy that lib/crypto/.kunitconfig currently uses toselect all the hidden library options isn't going to scale up well whenit needs to be repeated in two places.Instead let's go ahead and introduce an optionCRYPTO_LIB_ENABLE_ALL_FOR_KUNIT that depends on KUNIT and selects allthe crypto library options that have corresponding KUnit tests.Update lib/crypto/.kunitconfig to use this option.Link: https://lore.kernel.org/r/20260314035927.51351-2-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/.kunitconfig
