    s390/zcrypt: improve special ap message cmd handling · be534791
    Harald Freudenberger authored
    There exist very few ap messages which need to have the 'special' flag
    enabled. This flag tells the firmware layer to do some pre- and maybe
    postprocessing. However, it may happen that this special flag is
    enabled but the firmware is unable to deal with this kind of message
    and thus returns with reply code 0x41. For example older firmware may
    not know the newest messages triggered by the zcrypt device driver and
    thus react with reject and the named reply code. Unfortunately this
    reply code is not known to the zcrypt error routines and thus default
    behavior is to switch the ap queue offline.
    
    This patch now makes the ap error routine aware of the reply code and
    so userspace is informed about the bad processing result but the queue
    is not switched to offline state any more.
