* [SCSI] bfa: Fix to set vport FC host sysfs entriesKrishna Gudipati2012-05-223-1/+19

* [SCSI] bfa: Fix to defer vport delete handler invocation till firmware logo ↵Krishna Gudipati2012-04-254-32/+15
| | | | | | | | | | | | | | | | | | | response. Made changes to avoid queuing the vport delete work to IM driver work queue in the bfa_fcb_lport_delete() - since at this stage we are not completely done with using the vport structure as we are still waiting for the LOGO response from the fw in online state or just doing some cleanup. Since queuing up the vport delete work at this stage will result in the FC transport layer to clean up the vport before we get the response from firmware. Made changes to queue the port delete work to the IM driver work queue - from the bfa_fcs_vport_free() function since at this state we are done with using the vport data structure and the FCS state machine is completely cleaned up.

* [SCSI] bfa: Fix to avoid vport delete hang on request queue full scenario.Krishna Gudipati2012-03-283-4/+9

* [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.
