Module Name:    src
Committed By:   jdolecek
Date:           Tue Jul 14 10:44:34 UTC 2020

Modified Files:
        src/sys/dev/ic: ciss.c

Log Message:
only copy the actual command length in ciss_scsi_cmd(), instead of always
copying CISS_MAX_CDB bytes

Fixes reading past buffer memory triggered e.g. on kernel dump, reported
by KASAN:
ASan: Unauthorized Access In ...: Addr ... [16 bytes, read, RedZonePartial]

also do not pre-zero the cdb before copying cmd to it, there is no need for it
