jhb, cem: are these two modules still relevant?

Comment 3 John Baldwin freebsd_committer freebsd_triage 2020-04-22 15:43:14 UTC
Oh, it just needs to use FLAG_SOFTWARE still instead of FLAG_HARDWARE as these are accelerated software rather than accelerated hardware.

Alternatively, this should really be doing a lookup by name of "blake0" and using the returned 'crid' instead of the flag.  That's probably the real solution actually as it's meant to test that specific backend and not, say, some hardware offload that supports blake in the future.

(In reply to John Baldwin from comment #3)
Thanks for the analysis. I've tried with CRYPTO_FLAG_SOFTWARE but they failed with another message:

blake2_test:blake2b_vectors_x86  ->  failed: /usr/home/lwhsu/freebsd-src/tests/sys/opencrypto/blake2_test.c:108: alg 29 keylen 64, errno=22 (Invalid argument)
blake2_test:blake2s_vectors_x86  ->  failed: /usr/home/lwhsu/freebsd-src/tests/sys/opencrypto/blake2_test.c:108: alg 30 keylen 32, errno=22 (Invalid argument)

Haven't tried the "real solution" yet.

I have a stab at what I think is the real fix at https://reviews.freebsd.org/D24540.  It compiles, but I haven't run-tested it yet.

  Update blake2 accelerated software tests to work after OCF refactoring.

  - Lookup device drivers to test by name instead of assuming that the
    software / hardware flags will select specific drivers.
  - Set the sysctl to permit software /dev/crypto requests when testing
    the accelerated software blake2 driver.
