Memory freeing in iscsi_pool_free() looks wrong to me. Either q->pool can be NULL and this should be tested before dereferencing it, or it can't be NULL and it shouldn't be tested at all. As far as I can see, the only case where q->pool is NULL is on early error in iscsi_pool_init(). One possible way to fix the bug is thus to not call iscsi_pool_free() in this case (nothing needs to be freed anyway) and then we can get rid of the q->pool check.

When LLD supports direct data placement (ddp) for large receive of an scsi i/o coming into fc_fcp, we call into libfc_function_template's ddp_setup() to prepare for a ddp of large receive for this read I/O. When I/O is complete, we call the corresponding ddp_done() to get the length of data ddped as well as to let LLD do clean up. fc_fcp_ddp_setup()/fc_fcp_ddp_done() are added to setup and complete a ddped read I/O described by the given fc_fcp_pkt. They would call into corresponding ddp_setup/ddp_done implemented by the fcoe layer. Eventually, fcoe layer calls into LLD's ddp_setup/ddp_done provided through net_device Signed-off-by: NYi Zou <yi.zou@intel.com> Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com>

Use the I/O blocking mechanism in the FC transport class to allow faster failovers for multipathing: - Call fc_remote_port_delete early to set the rport to BLOCKED. - Check the rport status in queuecommand with fc_remote_portchkready to no longer accept new I/O for this port and fail the I/O with the appropriate scsi_cmnd result. - Implement the terminate_rport_io handler to abort all pending I/O requests - Return SCSI commands with DID_TRANSPORT_DISRUPTED while erp is running. - When updating the remote port status, check for late changes and update the remote ports status accordingly.

The current number based id ERP logging is replaced by a string based tag version. The benefit is an easier location of the code in question and the removal of the lengthy array referencing the individual messages. The string (7 bytes) based version does not use more space since those bytes were "used" anyway due to the alignment of the structure. The encoding of the 7 byte string is as follows [0-1] = filename [2-5] = task/function [6] = section Due to the character of this string (fixed length) a string termination is not required here.

Issue ELS ADISC requests from workqueue. This allows the link test request to be sent when the request queue is full due to I/O load for other remote ports. It also simplifies request queue locking, zfcp_fsf_send_fcp_command_task is now the only function that has interrupts disabled from the caller.

When the SCSI midlayer is running error recovery, the low-level error recovery in zfcp could be running and preventing the SCSI midlayer to issue error recovery requests.

PORT_PHYS_CLOSING is only set and cleared, but not actually used for status checking. PORT_INVALID_WWPN is set when the GID_PN request does not return a d_id for a remote port, e.g. when a remote port has been unplugged. For this case, the d_id is zero. In the erp we can check the d_id and use the normal escalation procedure that gives up after three retries and remove the special case. PORT_NO_WWPN is unused: Each port in the remote port list has a valid wwpn. The WKA ports are now tracked outside the port list. Remove the PORT_NO_WWPN flag, since this is no longer set for any port.

The SCSI core calls scsi_proc_hostdir_add() from within scsi_host_alloc(), but the corresponding scsi_proc_hostdir_rm() routine is called from within scsi_remove_host(). As a result, if a host is allocated and then deallocated without ever being registered, the host's directory in /proc is leaked. This patch (as1181b) fixes this bug in the SCSI core by moving scsi_proc_hostdir_rm() into scsi_host_dev_release().

sym53c8xx uses a command queue depth of 2 for untagged devices, without good reason. This _mostly_ seems to work ok, but it has caused me some subtle problems. For example, I have an application where one thread sends write commands to a tape drive, and another thread sends log sense polling commands. With a queue depth of 2, the polling commands end up being starved for long periods of time while multiple write commands are serviced (this may also be related to the fact the the sg driver queues commands in LIFO order). This problem is fixed by changing the queue depth to 1 for untagged devices. I have tested this change extensively with many different tape drives, medium changers, and disk drives (disk drives of course use tagged commands and are therefore unaffected by this patch).

sym_init_device() doesn't check if pci_iomap() fails. It also tries to map device RAM without first checking FE_RAM. 1) Move some initialization from sym_init_device() to the top of sym2_probe(). 2) Rename sym_init_device() to sym_iomap_device(). 3) Call sym_iomap_device() after sym_check_supported() instead of before so that device->chip.features will be set. 4) Check FE_RAM in sym_iomap_device() before mapping RAM. 5) If sym_iomap_device() cannot map registers, then abort. 6) If sym_iomap_device() cannot map RAM, then fall back to not using RAM and continue. 7) Remove the check for FE_RAM in sym_attach() since dev->ram_base is now always set correctly.

During sym2_probe(), sym_init_device() does pci_iomap(), but there is no corresponding pci_iounmap() if an error occurs before sym_attach() copies sym_device::s.{ioaddr,ramaddr} to np. 1) Add the sym_iounmap_device() function. 2) Call sym_iounmap_device() if an error occurs between sym_init_device() and the time sym_attach() allocates np. 3) Make sym_attach() copy sym_device::s.{ioaddr,ramaddr} to np before calling any function that can fail so that sym_free_resources() will do the unmap instead of sym_iounmap_device(). Also fixed by this patch: During sym2_probe(), if sym_check_raid() returns nonzero, then pci_release_regions() is never called.
