lib/crypto: tests: Depend on library options rather than selecting them 2026-03-01T03:17:30+00:00 Eric Biggers ebiggers@kernel.org 2026-02-26T19:17:49+00:00 4478e8eeb87120c11e90041864c2233238b2155a The convention for KUnit tests is to have the test kconfig options visible only when the code they depend on is already enabled. This way only the tests that are relevant to the particular kernel build can be enabled, either manually or via KUNIT_ALL_TESTS. Update lib/crypto/tests/Kconfig to follow that convention, i.e. depend on the corresponding library options rather than selecting them. This fixes an issue where enabling KUNIT_ALL_TESTS enabled non-test code. This does mean that it becomes a bit more difficult to enable *all* the crypto library tests (which is what I do as a maintainer of the code), since doing so will now require enabling other options that select the libraries. Regardless, we should follow the standard KUnit convention. I'll also add a .kunitconfig file that does enable all these options. Note: currently most of the crypto library options are selected by visible options in crypto/Kconfig, which can be used to enable them without too much trouble. If in the future we end up with more cases like CRYPTO_LIB_CURVE25519 which is selected only by WIREGUARD (thus making CRYPTO_LIB_CURVE25519_KUNIT_TEST effectively depend on WIREGUARD after this commit), we could consider adding a new kconfig option that enables all the library code specifically for testing.

 "Core & protocols:

   - A significant effort all around the stack to guide the compiler to

     for small helper and stack canary overhead in the fast-path.

     This generates better and faster code with very small or no text
     size increases, as in many cases the call generated more code than
     the actual inlined helper.

   - Extend AccECN implementation so that is now functionally complete,

     by up to ~30%.

     that are safer in crash scenarios.

   - Improve the TCP ipv6 output path to cache the flow information,
     saving cpu cycles, reducing cache line misses and stack use.

   - Improve netfilter packet tracker to resolve clashes for most
     protocols, avoiding unneeded drops on rare occasions.

   - Add IP6IP6 tunneling acceleration to the flowtable infrastructure.

   - Reduce tcp socket size by one cache line.

   - Notify neighbour changes atomically, avoiding inconsistencies
     between the notification sequence and the actual states sequence.

   - Add vsock namespace support, allowing complete isolation of vsocks
     across different network namespaces.

   - Improve xsk generic performances with cache-alignment-oriented
     optimizations.

   - Support netconsole automatic target recovery, allowing netconsole
     to reestablish targets when underlying low-level interface comes
     back online.

  Driver API:

   - Support for switching the working mode (automatic vs manual) of a
     DPLL device via netlink.

   - Introduce PHY ports representation to expose multiple front-facing
     media ports over a single MAC.

   - Introduce "rx-polarity" and "tx-polarity" device tree properties,
     to generalize polarity inversion requirements for differential
     signaling.

   - Add helper to create, prepare and enable managed clocks.

  Device drivers:

   - Add Huawei hinic3 PF etherner driver.

   - Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
     controller.

   - Add ethernet driver for MaxLinear MxL862xx switches

   - Remove parallel-port Ethernet driver.

   - Convert existing driver timestamp configuration reporting to
     hwtstamp_get and remove legacy ioctl().

   - Convert existing drivers to .get_rx_ring_count(), simplifing the RX
     ring count retrieval. Also remove the legacy fallback path.

   - Ethernet high-speed NICs:
      - Broadcom (bnxt, bng):
         - bnxt: add FW interface update to support FEC stats histogram
           and NVRAM defragmentation
         - bng: add TSO and H/W GRO support
      - nVidia/Mellanox (mlx5):
         - improve latency of channel restart operations, reducing the

         - add TSO support for UDP over GRE over VLAN
         - add flow counters support for hardware steering (HWS) rules
         - use a static memory area to store headers for H/W GRO,
           leading to 12% RX tput improvement
      - Intel (100G, ice, idpf):
         - ice: reorganizes layout of Tx and Rx rings for cacheline
