#     crypto: af_alg - Work around empty control messages without MSG_MORE
#     
#     The iwd daemon uses libell which sets up the skcipher operation with
#     two separate control messages.  As the first control message is sent
#     without MSG_MORE, it is interpreted as an empty request.
#     
#     While libell should be fixed to use MSG_MORE where appropriate, this
#     patch works around the bug in the kernel so that existing binaries
#     continue to work.
#     
#     We will print a warning however.
#     
#     A separate issue is that the new kernel code no longer allows the
#     control message to be sent twice within the same request.  This
#     restriction is obviously incompatible with what iwd was doing (first
#     setting an IV and then sending the real control message).  This
#     patch changes the kernel so that this is explicitly allowed.
