[PATCH 0/4] crypto: testmgr - always print the actual driver name

[Eric Biggers <ebiggers@kernel.org>]

When alg_test() is called from tcrypt.ko rather than from the algorithm
registration code, "driver" is actually the algorithm name, not the
driver name.  So it shouldn't be used in places where a driver name is
wanted, e.g. when reporting a test failure or when checking whether the
driver is the generic driver or not.

See https://lkml.kernel.org/r/20200910122248.GA22506@Red for an example
where this caused a problem.  The self-tests reported "alg: ahash: md5
test failed", but it wasn't mentioned which md5 implementation it was.

Fix this by getting the driver name from the crypto tfm object that
actually got allocated.

Eric Biggers (4):
  crypto: aead - add crypto_aead_driver_name()
  crypto: testmgr - always print the actual hash driver name
  crypto: testmgr - always print the actual AEAD driver name
  crypto: testmgr - always print the actual skcipher driver name
