Hello,
we don't have enough knowledge to deeply analyze the impact of this commit
to stress-ng.af-alg performance tests.
along with the major kpi improvement:
7756377 +113.7% 16578454 stress-ng.af-alg.ops_per_sec
we also noticed lots of misc tests seem have changes, e.g.
697423 -9.5% 630908 ± 2% stress-ng.af-alg.aes_cipher_ops/sec
245103 -100.0% 0.00 stress-ng.af-alg.blowfish_cipher_ops/sec
369646 -100.0% 0.00 stress-ng.af-alg.camellia_cipher_ops/sec
162192 -100.0% 0.00 stress-ng.af-alg.cast5_cipher_ops/sec
115113 -100.0% 0.00 stress-ng.af-alg.cast6_cipher_ops/sec
we don't know if these are expected behavior upon 2f204fe718.
so this report is just FYI what we observed in our tests.
kernel test robot noticed a 113.7% improvement of stress-ng.af-alg.ops_per_sec on:
commit: 2f204fe718f5bf519013cc2536ad7bb2cbb51661 ("crypto: af_alg - Add af_alg_restrict sysctl, defaulting to 1")

That commit makes AF_ALG block access to some algorithms by default,
overridable by a sysctl. Apparently these performance tests
misinterpret that as a change in performance.
It actually doesn't make much sense to do performance testing on AF_ALG
at all anymore, given that AF_ALG is deprecated. A limited form of
AF_ALG is being left in place just for backwards compatibility with a
few programs. None of those programs use it in a performance-critical
way, as far as I know.
To the extent that it's still done at all, it shouldn't test random
algorithms like "ecb(cast5)" that are obsolete and unused.
