From: Hiral Shah Date: Mon, 10 Nov 2014 20:54:33 +0000 (-0800) Subject: Fnic: Memcopy only mimumum of data or trace buffer X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=042b356a5fcf3c5a99c34208eefc572454a330bf;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Fnic: Memcopy only mimumum of data or trace buffer In case of receive path, we do not have eth header or fcoe header available when we take a trace so we fill the fc trace buffer with 0xff for both values. We copy only mimimum of received data or trace buffer size - fc header - eth and fcoe header - Increment fnic version from 1.6.0.12 to 1.6.0.13 Signed-off-by: Hiral Shah Signed-off-by: Sesidhar Baddela Signed-off-by: Anil Chintalapati Signed-off-by: Christoph Hellwig --- diff --git a/drivers/scsi/fnic/fnic.h b/drivers/scsi/fnic/fnic.h index 69dee6838678..dbc69ad2d1c4 100644 --- a/drivers/scsi/fnic/fnic.h +++ b/drivers/scsi/fnic/fnic.h @@ -39,7 +39,7 @@ #define DRV_NAME "fnic" #define DRV_DESCRIPTION "Cisco FCoE HBA Driver" -#define DRV_VERSION "1.6.0.12" +#define DRV_VERSION "1.6.0.13" #define PFX DRV_NAME ": " #define DFX DRV_NAME "%d: " diff --git a/drivers/scsi/fnic/fnic_trace.c b/drivers/scsi/fnic/fnic_trace.c index acf1f95cb5c5..65a9bde26974 100644 --- a/drivers/scsi/fnic/fnic_trace.c +++ b/drivers/scsi/fnic/fnic_trace.c @@ -624,12 +624,12 @@ int fnic_fc_trace_set_data(u32 host_no, u8 frame_type, if (frame_type == FNIC_FC_RECV) { eth_fcoe_hdr_len = sizeof(struct ethhdr) + sizeof(struct fcoe_hdr); - fc_trc_frame_len = fc_trc_frame_len + eth_fcoe_hdr_len; memset((char *)fc_trace, 0xff, eth_fcoe_hdr_len); /* Copy the rest of data frame */ memcpy((char *)(fc_trace + eth_fcoe_hdr_len), (void *)frame, min_t(u8, fc_trc_frame_len, - (u8)(FC_TRC_SIZE_BYTES - FC_TRC_HEADER_SIZE))); + (u8)(FC_TRC_SIZE_BYTES - FC_TRC_HEADER_SIZE + - eth_fcoe_hdr_len))); } else { memcpy((char *)fc_trace, (void *)frame, min_t(u8, fc_trc_frame_len,
