* [SCSI] mpt fusion: Use menuconfig objectsJan Engelhardt2007-10-12
| | | | | | | | | | | Change Kconfig objects from "menu, config" into "menuconfig" so that the user can disable the whole feature without having to enter the menu first.

* [SCSI] srp_transport: convert to use supported_mode attributeFUJITA Tomonori2007-10-12

* [SCSI] fc_transport: add target driver supportFUJITA Tomonori2007-10-12
| | | | | | | | | | | | | | This adds minimum target driver support like the srp transport does: - fc_remote_port_{rolechg,delete} calls scsi_tgt_it_nexus_{create,destroy} for target drivers. - add callbacks to notify target drivers of the nexus and tmf operation results to fc_function_template.

* [SCSI] add supported_mode and active_mode attributes to the hostFUJITA Tomonori2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds supported_mode and active_mode attributes to /sys/class/sys_host/hostX/ for specifying the mode that a lld supports and the currently activated mode. The output format is similar to fc rport roles: luce:/sys/class/scsi_host/host0$ cat supported_mode Initiator luce:/sys/class/scsi_host/host0$ cat active_mode Initiator The mode values uses bitmap since we would support dual-mode llds in the future like this: luce:/sys/class/scsi_host/host0$ cat supported_mode Initiator, Target The supported_mode attribute looks at a scsi_host_template and the active_mode attribute looks at a scsi_host. We would add a hook to a scsi_host_template to change the active_mode attribute dynamically. But now there is no hook since no lld supports that feature.

* [SCSI] lpfc: fix potential overflow of hbqs arrayJesper Juhl2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Coverity checker noticed that we may overrun a statically allocated array in drivers/scsi/lpfc/lpfc_sli.c::lpfc_sli_hbqbuf_find(). The case is this; In 'struct lpfc_hba' we have #define LPFC_MAX_HBQS 4 ... struct lpfc_hba { ... struct hbq_s hbqs[LPFC_MAX_HBQS]; ... }; But then in lpfc_sli_hbqbuf_find() we have this code hbqno = tag >> 16; if (hbqno > LPFC_MAX_HBQS) return NULL; if 'hbqno' ends up as exactely 4, then we won't return, and then this list_for_each_entry(d_buf, &phba->hbqs[hbqno].hbq_buffer_list, list) { will cause an overflow of the statically allocated array at index 4, since the valid indices are only 0-3. I propose this patch, that simply changes the 'hbqno > LPFC_MAX_HBQS' into 'hbqno >= LPFC_MAX_HBQS' as a possible fix.

Delete the sections on: - kernels supported - other files modified (obsolete) - source comments (obsolete) - tests to run - release history (that's what a VCS is for) - contacting connectcom (the domain has expired and the phone number is now in use by another organisation) Known problems/fix list is moved down to the section where jejb put his FIXME.

| | | | | | | | | | | | | Use memcpy to initialise eep_config instead of a loop. For AdvInitFrom38C1600EEP where we need to modify the default EEPROM configuration, do it after the loop, and do it using the structure definition, not by finding the right byte.

* [SCSI] advansys: Stop using n_io_port in Scsi_Host structureMatthew Wilcox2007-10-12
| | | | | | | | | | n_io_port isn't suitable for advansys because some of the boards have more than 255 bytes of io port space.
