* [SCSI] bfa: don't leak mem in bfad_im_bsg_els_ct_request()Jesper Juhl2012-02-191-2/+2
| | | | | | | | | | | | | | | If 'drv_fcxp = kzalloc(sizeof(struct bfad_fcxp), GFP_KERNEL);' fails and returns NULL, then we'll leak the memory allocated to 'bsg_fcpt' when we jump to 'out:' and the variable subsequently goes out of scope. Also remove the cast of the kzalloc() return value. kzalloc() returns a void* which is implicitly converted, so the explicit cast is pointless.

* [SCSI] bfa: Implement LUN Masking feature using the SCSI Slave Callouts.Krishna Gudipati2012-01-116-4/+112
| | | | | | | | | | | | | | | | This patch re-implements LUN Masking feature using SCSI Slave Callouts. With the new design in the slave_alloc entry point; for each new LUN discovered we check with our internal LUN Masking config whether to expose or to mask this particular LUN. We return -ENXIO (No such device or address) from slave_alloc for the LUNs we don't want to be exposed. We also notify the SCSI mid-layer to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based scan translates to a scan abort. This patch also handles the dynamic lun masking config change from enable to disable or vice-versa by resetting sdev_bflags of LUN 0 appropriately.

Previously only a single queue per queue group was used. - Added function tag to BFI message header. Only used by FC BFI messages. Used to translate host tag to firmware tag. bfa_lpuid() is changed to bfa_fn_lpu() that encodes both PCI function and port ID in BFI message header.
