Kernel panics due to NULL lport while executing the log message because of synchronization issues between libfc and scsi transport fc. Checking for NULL pointers at the beginning of this routine would resolve the issue from kernel panic point of view. Signed-off-by:

Hitting BUG_ON(io_req->abts_done) in fnic_rport_exch_reset in case of timing issue and also to some extent locking issue where abts and terminate is happening around same timing. The code changes are intended to update CMD_STATE(sc) and io_req->abts_done together. Signed-off-by:

Issue was seen when SCSI buffer address is more than 40 bits in system with more than 1.1TB RAM. When SCSI buffer is passed to VIC, it is failing to map to correct buffer address, as DMA mask is set to 40 bits in driver initialization. Corrected DMA_MASK from 40-bits to 64-bits to avoid masking 41-64 bits addresses. Signed-off-by:

This patch fixes an out-of-bounds error in sd_read_cache_type(), found by Google's AddressSanitizer tool. When the loop ends, we know that "offset" lies beyond the end of the data in the buffer, so no Caching mode page was found. In theory it may be present, but the buffer size is limited to 512 bytes.

This patch will add big endian architecture support to megaraid_sas driver. The support added is for LSI MegaRAID all generation controllers- (3Gb/s, 6Gb/s and 12 Gb/s controllers). We have done basic sanity test @ppc64 arch and @x86_64. Additional testing/observations are welcome. [jejb: fix up rejections] Signed-off-by:

IACTH(Interrupt aggregation counter threshold) value is allowed up to 0x1F and current setting value is the maximum. This value is related with NUTRS(max:0x20) of HCI's capability. Considering HCI controller doesn't support the maximum, IACTH setting should be adjusted with possible value. For that, existing 'ufshcd_config_int_aggr' is split into two part [reset, configure].

Unlike 'GOOD' and 'CHECK CONDITION', other status values in Response UPIU may or may not contain sense data. That is returning sense data isn't obvious. So, in this case the Data Segment Length field should be checked. If a non-zero value, it means that UPIU has Sense Data in the Data Segment area. Signed-off-by:
