Subject: [PATCH 03/15] crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm
|
|
allocations
|
|
|
|
'cipher' algorithms (single block ciphers) are always synchronous, so
|
|
passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
|
|
effect. Many users therefore already don't pass it, but some still do.
|
|
This inconsistency can cause confusion, especially since the way the
|
|
'mask' argument works is somewhat counterintuitive.
|
|
|
|
Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.
|
|
|
|
This patch shouldn't change any actual behavior.
