[af_alg v2] crypto:af_alg cast ki_complete ternary op to int

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



when libkcapi test is executed  using HW accelerator, cipher operation
return -74.Since af_alg_async_cb->ki_complete treat err as unsigned int,
libkcapi receive 429467222 even though it expect -ve value.

Hence its required to cast resultlen to int so that proper
error is returned to libkcapi.
