Subject: re: [SCSI] esas2r: ATTO Technology ExpressSAS 6G SAS/SATA RAID Adapter Driver
Date: Thu, 29 Aug 2013 11:46:04 +0300	[thread overview]
Message-ID: <20130829084604.GD14334@elgon.mountain> (raw)

Hello Bradley Grove,

The patch 17adeb6dabbe: "[SCSI] esas2r: ATTO Technology ExpressSAS 6G
SAS/SATA RAID Adapter Driver" from Aug 23, 2013, leads to the
following Smatch warning:
"drivers/scsi/esas2r/esas2r_vda.c:312 esas2r_complete_vda_ioctl()
	 error: format string overflow. buf_size: 4 length: 5"

drivers/scsi/esas2r/esas2r_vda.c
   312                          sprintf((char *)&cfg->data.init.fw_release,
                                                 ^^^^^^^^^^^^^^^^^^^^^^^^^
This is a u32 but we are writing 4 characters and a NUL so it ends up
putting the NUL in cfg->data.init.epoch_time.

   313                                  "%1d.%02d",
   314                                  (int)LOBYTE(le16_to_cpu(rsp->fw_release)),
   315                                  (int)HIBYTE(le16_to_cpu(rsp->fw_release)));

regards,
dan carpenter
