2013-09-11[SCSI] fnic: Kernel panic while running sh/nosh with max lun cfgSesidhar Beddel1-3/+20
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.

2013-09-11[SCSI] fnic: Hitting BUG_ON(io_req->abts_done) in fnic_rport_exch_resetSesidhar Beddel1-28/+42
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.

2013-09-11[SCSI] fnic: On system with >1.1TB RAM, VIC fails multipath after boot upBrian Uchino1-4/+4
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.

2013-09-11[SCSI] sd: Fix potential out-of-bounds accessAlan Stern1-8/+3
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.

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].

2013-09-03[SCSI] sg: use rwsem to solve race during exclusive openVaughan Cao1-38/+41
A race condition may happen if two threads are both trying to open the same sg with O_EXCL simultaneously. It's possible that they both find fsds list is empty and get_exclude(sdp) returns 0, then they both call set_exclude() and break out from wait_event_interruptible and resume open. Now use rwsem to protect this process. Exclusive open gets write lock and others get read lock. The lock will be held until file descriptor is closed. This also leads 'exclude' only a status rather than a check mark.
