[PATCH 0/8] crypto: api - priorize tested algorithms in lookup

[Nicolai Stange]

Hi all,

my initial goal had been to make the algorithm lookup prefer usable
instances over ones where the tests are still pending. In my first attempt
I realized that the code in crypto_alg_lookup() became quite convoluted
and that it could get streamlined somewhat by consolidating
CRYPTO_ALG_TESTED handling for lookup larvals a bit.

This cleanup can be found in [1/8] - [7/8] and might perhaps be worth
considering on its own, independent of whether or not you deem the
final [8/8], the patch implementing my original goal of priorizing
algorithms in working state, suitable for upstream inclusion.

This series is based on current herbert/cryptodev-2.6 master.

All patches have been tested with tcrypt.ko as well as the kernel/crypto
testcases from LTP.

Thanks!

Nicolai

Nicolai Stange (8):
  crypto: af_alg - reject requests for untested algorithms
  crypto: user - reject requests for untested algorithms
  crypto: api - only support lookups for specific CRYPTO_ALG_TESTED
    status
  crypto: api - don't add larvals for !(type & CRYPTO_ALG_TESTED)
    lookups
  crypto: api - always set CRYPTO_ALG_TESTED in lookup larvals'
    ->mask/type
  crypto: api - make crypto_alg_lookup() consistently check for failed
    algos
  crypto: api - lift common mask + type adjustment to
    crypto_larval_lookup()
  crypto: api - make the algorithm lookup priorize non-larvals
