crypto: gcm - fix another complete call in complete fuction
The flow of the complete function (xxx_done) in gcm.c is as follow:
void complete(struct crypto_async_request *areq, int err)
{
struct aead_request *req = areq->data;
if (!err) {
err = async_next_step();
if (err == -EINPROGRESS || err == -EBUSY)
return;
}
complete_for_next_step(areq, err);
}
But *areq may be destroyed in async_next_step(), this makes
complete_for_next_step() can not work properly. To fix this, one of
following methods is used for each complete function.
- Add a __complete() for each complete(), which accept struct
aead_request *req instead of areq, so avoid using areq after it is
destroyed.
- Expand complete_for_next_step().
The fixing method is based on the idea of Herbert Xu.
