From 4f8d1bd273684385fa8e8e4f9b8bd6107016ece8 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 16 Mar 2013 13:07:56 +0300 Subject: [SCSI] csiostor: off by one error We need to store PROTO_ERR_IMPL_LOGO (26) things here, but the first element isn't used so the array should have 27 elements. This matches fwevt_to_rnevt[] which has 27 elements. The patch solves a Smatch static checker warning on my system: drivers/scsi/csiostor/csio_rnode.c:880 csio_rnode_fwevt_handler() error: buffer overflow '(rn)->stats.n_evt_fw' 26 <= 26 Signed-off-by: Dan Carpenter Acked-by: Naresh Kumar Inna Signed-off-by: James Bottomley --- drivers/scsi/csiostor/csio_rnode.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/scsi/csiostor/csio_rnode.h') diff --git a/drivers/scsi/csiostor/csio_rnode.h b/drivers/scsi/csiostor/csio_rnode.h index 65940096a80d..433434221222 100644 --- a/drivers/scsi/csiostor/csio_rnode.h +++ b/drivers/scsi/csiostor/csio_rnode.h @@ -63,7 +63,7 @@ struct csio_rnode_stats { uint32_t n_err_nomem; /* error nomem */ uint32_t n_evt_unexp; /* unexpected event */ uint32_t n_evt_drop; /* unexpected event */ - uint32_t n_evt_fw[PROTO_ERR_IMPL_LOGO]; /* fw events */ + uint32_t n_evt_fw[PROTO_ERR_IMPL_LOGO + 1]; /* fw events */ enum csio_rn_ev n_evt_sm[CSIO_RNFE_MAX_EVENT]; /* State m/c events */ uint32_t n_lun_rst; /* Number of resets of * of LUNs under this -- cgit v1.2.3-55-g7522
