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. Signed-off-by: -

The 700+-line comment at the top of the advansys driver fits more comfortably in Documentation/scsi. 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. I think it was wrong for big-endian machines. Also delete some non-useful comments and prototypes. Signed-off-by:

The cfg structures are supposed to be disposable after initialisation; with the 'dev' used for DMA mapping in there, that's not possible. Move the dev to the board. Also inline AscInitFromAscDvcVar into its only caller, remove some unnecessary prototypes and sort out a few minor formatting issues. Signed-off-by:

n_io_port isn't suitable for advansys because some of the boards have more than 255 bytes of io port space. There's already a driver-private replacement, asc_n_io_port, but for some reason the driver was still setting and occasionally reporting n_io_port. Signed-off-by:

At some point during Linux 2.1 development, ioremap() gained the ability to handle addresses which weren't page-aligned. Also expand the CONFIG_PCI range to encompass that entire section of wide board initialisation, since all wide boards are PCI. Signed-off-by:

Use slave_configure() to do all the work that used to be done in AscInquiryHandling and AdvInquiryHandling. Split slave_configure into two functions, one for wide and one for narrow controllers. Remove some unused definitions, duplicate definitions, unnecessary declarations, and scsireqq, cap_info and inquiry from struct asc_board. Signed-off-by:

Make sure the resources are reserved and released by all the callers of advansys_board_found(). This eliminates the check_region-style race. It also allows us to use the pci_request_regions() API. Signed-off-by:

Register two isa_drivers, one for ISA and one for VLB, in order to preserve detection order. When deleting advansys_detect, we lose the last vestiges of the code that limited IO port scanning. This code has been effectively disabled for many years anyway; I'll restore it in a module_param later. We also lose the code that placed all ISA PnP cards into WaitForKey state -- drivers shouldn't be doing this anyway. The asc_host array goes away too. Also remove some IOADR and other definitions, such as ASC_NUM_BOARD_SUPPORTED. Signed-off-by:

- Add a pci_driver interface for the PCI advansys devices (for ISA/EISA/VLB devices, we still call advansys_detect). - Many functions are converted from __init to __devinit to allow hotplug PCI to work. - Only keep devices found by advansys_detect in the asc_host list. - Rename asc_board_count to asc_legacy_count. New asc_board_count is only used to generate a unique name for each device. - Remove some now-unused macros and struct definitions Signed-off-by:

The interrupt routines used to walk the list of Scsi_Hosts belonging to this driver to make sure that the scsi_cmnd belonged to one of them. This is a waste of time and gets in the way of later cleanups, so delete it. Signed-off-by:

Pass the Scsi_Host to the interrupt handler, rather than polling all hosts for each interrupt. Return IRQ_NONE if we didn't handle this interrupt Don't set the IRQF_DISABLED flag; this is not a fast-executing interrupt handler. Signed-off-by:

unsigned short is too small for sizeof(struct scatterlist) * min(q->max_hw_segments, q->max_phys_segments). This fixes memory leak with 4096 segments since 16 (likely sg size with x86) * 4096 sets sglist_len to zero. This might not happen without sg chaining support. Signed-off-by:

Stress-testing and some thought has revealed some places where asynchronous scanning needs some more attention to locking. - Since async_scan is a bit, we need to hold the host_lock while modifying it to prevent races against other CPUs modifying the word that bit is in. This is probably a theoretical race for the moment, but other patches may change that. - The async_scan bit means not only that this host is being scanned asynchronously, but that all the devices attached to this host are not yet added to sysfs. So we must ensure that this bit is always in sync. I've chosen to do this with the scan_mutex since it's already acquired in most of the right places. - If the host changes state to deleted while we're in the middle of a scan, we'll end up with some devices on the host's list which must be deleted. Add a check to scsi_sysfs_add_devices() to ensure the host is still running. - To avoid the async_scan bit being protected by three locks, the async_scan_lock now only protects the scanning_list.

This adds minimum target driver support: - srp_rport_{add,del} calls scsi_tgt_it_nexus_{create,destroy} for target drivers. - add a callback to notify target drivers of the nexus operation results to srp_function_template. Signed-off-by: -
FUJITA Tomonori authored
tgt uses scsi_host as I_T nexus. This works for ibmvstgt because it creates one scsi_host for one initiator. However, other target drivers don't work like that. This adds I_T nexus support, which enable one scsi_host to handle multiple initiators. New scsi_tgt_it_nexus_create/destroy functions are expected be called transport classes. For example, ibmvstgt creates an initiator remote port, then the srp transport calls tgt_it_nexus_create. tgt doesn't manages I_T nexus, instead it tells tgtd, user-space daemon, to create a new I_T nexus. On the receiving the response from tgtd, tgt calls shost->transportt->it_nexus_response. transports should notify a lld. The srp transport uses it_nexus_response callback in srp_function_template to do that. Signed-off-by:

This adds a 'roles' attribute to rport like transport_fc. The role can be initiator or target. That is, the initiator driver creates target remote ports and the target driver creates initiator remote ports. Signed-off-by:
