2013-09-27SCSI: Allow MPT Fusion SAS 3.0 driver to be built into the kernelGreg Kroah-Hartman1-1/+1
commit 9807b4d94911be4e4efb9a08481b24292a9edf8a upstream. Right now the Makefile for the mpt3sas driver does not even allow the driver to be built into the kernel. So fix that up, as there doesn't seem to be any obvious reason why this shouldn't be done.

2013-07-29SCSI: mpt3sas: fix for kernel panic when driver loads with HBA conected to ↵Sreekanth Reddy1-0/+14
non LUN 0 configured expander commit b65cfedf4560af65305bd7b3b9f26c02c6fb3660 upstream. With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created then SCSI scan procedure calls target_alloc, slave_alloc call back functions for LUN 0 and slave_destory() for same LUN 0. In these kind of cases within slave_destroy, pointer to scsi_target in _sas_device structure is set to NULL, following which when slave_alloc for LUN 1 is called then starget would not be set properly for this LUN. So, scsi_target pointer pointing to NULL value would lead to a crash later in the discovery procedure. To solve this issue set the sas_device's scsi_target pointer to scsi_device's scsi_target if it is NULL earlier in slave_alloc callback function.

2013-07-29SCSI: mpt3sas: Infinite loops can occur if ↵Sreekanth Reddy1-12/+4
MPI2_IOCSTATUS_CONFIG_INVALID_PAGE is not returned commit 14be49ac965ebd3f8561d57e01ddb22f93f9b454 upstream. Infinite loop can occur if IOCStatus is not equal to MPI2_IOCSTATUS_CONFIG_INVALID_PAGE value in the while loops in functions _scsih_search_responding_sas_devices, _scsih_search_responding_raid_devices and _scsih_search_responding_expanders So, Instead of checking for MPI2_IOCSTATUS_CONFIG_INVALID_PAGE value, in this patch code is modified to check for IOCStatus not equals to MPI2_IOCSTATUS_SUCCESS to break the while loop.

2013-01-29[SCSI] mpt3sas: cut and paste bug storing trigger mpiDan Carpenter1-1/+1
ioc->diag_trigger_mpi is an SL_WH_MPI_TRIGGERS_T struct. There is a cut and paste error here and SL_WH_EVENT_TRIGGERS_T is used instead of SL_WH_MPI_TRIGGERS_T. Since the SL_WH_EVENT_TRIGGERS_T is smaller than SL_WH_MPI_TRIGGERS_T, it means we only clear part of the buffer. I've changed it to use sizeof(ioc->diag_trigger_mpi) which is a bit simpler.

2013-01-04Drivers: scsi: remove __dev* attributes.Greg Kroah-Hartman1-3/+2
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

These driver files are initially, substantially similar to mpt2sas but, because mpt2sas is going into maintenance mode and mp3sas will become heavily developed, we elected to keep the code bases separate.
