After checking this issue again, I see that it is not triggerable in the current code as the different af_alg users make sure that this function is not called with 0. I only triggered this issue during experimenting with the algif_skcipher and algif_aead revamp as requested by you. During those experiments, I invoked af_alg_make_sg with a len = 0. Thus, this patch is not applicable for stable and 4.11. Yet, I would suggest to consider this patch as a safeguard for any potential programming errors. Ciao Stephan
