Is the payload still be offloaded as plaintext? Otherwise we wouldn't have
use_rdma_mr... So this rather looks like a fix for the non encrypted case.
The "inline"[*] PDUs are encrypted, but the direct RDMA data transmission is
not. I'm not sure if this is a bug in ksmbd.
It's a bug in the client!
As I understand it, encrypting and decrypting the directly transferred
data would need to be done by the NIC, not the cifs driver.
No, the encryption needs to happen above the RDMA/NIC layer.
