After commit 6c11dc06 ("scsi: hisi_sas: Fix IRQ checks") we have the error codes returned by platform_get_irq() ready for the propagation upsream in interrupt_init_v1_hw() -- that will fix still broken deferred probing. Let's propagate the error codes from devm_request_irq() as well since I don't see the reason to override them with -ENOENT...

The controller expects all data it sends/receives to be little-endian. Therefore, the packet struct definitions should use the __le16/32/64 types. Once those are correct, sparse reports several issues with the driver code, which are fixed here as well. The main issue observed was at the call to scsi_set_resid(), where the byteswapped parameter would eventually trigger the alignment check at drivers/scsi/sd.c:2009. At that point, the kernel would continuously complain about an "Unaligned partial completion", and no further I/O could occur. This gets the controller working on big endian powerpc64.

Currently, all command packet structs used by this driver are packed. However, only one (TW_SG_Entry) actually needs to be packed, because it uses 64-bit addresses at 32-bit alignment. To improve the quality of generated code, stop packing all of the other command packet structs. This requires adjusting the type of one misaligned "reserved" member. After this change, pahole reports that only one type had its layout change: the tw_compat_info member of TW_Device_Extension is now naturally aligned.

If rport target discovery commands fail for some reason, they get retried up to a set number of retries. Once the retry limit is exceeded, the target is deleted. In order to delete the target, we either need to do an implicit logout or a move login. In the move login case, if the move login fails, we want to retry it. This ensures the retry counter gets reinitialized so the move login will get retried. Link: https://lore.kernel.org/r/1620756740-7045-4-git-send-email-brking@linux.vnet.ibm.comSigned-off-by:

If fast fail is enabled and we encounter a WWPN moving from one port id to another port id with I/O outstanding, if we use the move login MAD, although it will work, it will leave any outstanding I/O still outstanding to the old port id. Eventually, the SCSI command timers will fire and we will abort these commands, however, this is generally much longer than the fast fail timeout, which can lead to I/O operations being outstanding for a long time. This patch changes the behavior to avoid the move login if fast fail is enabled. Once terminate_rport_io cleans up the rport, then we force the target back through the delete process, which re-drives the implicit logout, then kicks us back into discovery where we will discover the WWPN at the new location and do a PLOGI to it.

When service is being performed on an SVC with NPIV enabled, the WWPN of the canister / node being serviced fails over to the another canister / node. This looks to the ibmvfc driver as a WWPN moving from one SCSI ID to another. The driver will first attempt to do an implicit logout of the old SCSI ID. If this works, we simply delete the rport at the old location and add an rport at the new location and the FC transport class handles everything. However, if there is I/O outstanding, this implicit logout will fail, in which case we will send a "move login" request to the VIOS. This will cancel any outstanding I/O to that port, logout the port, and PLOGI the new port. Recently we've encountered a scenario where the move login fails. This was resulting in an attempted plogi to the new scsi id, without the old scsi id getting logged out, which is a VIOS protocol violation. To solve this, we want to keep tracking the old scsi id as the current scsi id. That way, once terminate_rport_io cancels the outstanding i/o, it will send us back through to do an implicit logout of the old scsi id, rather than the new scsi id, and then we can plogi the new scsi id.

The structure pointer passed to container_of() is never NULL; that was already checked. That means that the result of container_of() operations on it is also never NULL, even though se_node_acl is the first element of the structure embedding it. On top of that, it is misleading to perform a NULL check on the result of container_of() because the position of the contained element could change, which would make the test invalid. Remove the unnecessary NULL check. As it turns out, the container_of operation was only made for the purpose of the NULL check. If the container_of is actually needed, it is repeated later. Remove the container_of operation as well. The NULL check was identified and removed with the following Coccinelle script. @@ type t; identifier v; statement s; @@ <+...

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct aac_raw_io2 instead of one-element array, and use the struct_size() helper. Also, this helps with the ongoing efforts to enable -Warray-bounds by fixing the following warnings: drivers/scsi/aacraid/aachba.c: In function ‘aac_build_sgraw2’: drivers/scsi/aacraid/aachba.c:3970:18: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 3970 | if (rio2->sge[j].length % (i*PAGE_SIZE)) { | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:3974:27: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 3974 | nseg_new += (rio2->sge[j].length / (i*PAGE_SIZE)); | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4011:28: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4011 | for (j = 0; j < rio2->sge[i].length / (pages * PAGE_SIZE); ++j) { | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4012:24: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4012 | addr_low = rio2->sge[i].addrLow + j * pages * PAGE_SIZE; | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4014:33: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4014 | sge[pos].addrHigh = rio2->sge[i].addrHigh; | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4015:28: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4015 | if (addr_low < rio2->sge[i].addrLow) | ~~~~~~~~~^~~ [1] https://en.wikipedia.org/wiki/Flexible_array_member [2] https://www.kernel.org/doc/html/v5.9/process/deprecated.html#zero-length-and-one-element-arrays Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/109 Link: https://lore.kernel.org/lkml/60414244.ur4%2FkI+fBF1ohKZs%25lkp@intel.com/ Link: https://lore.kernel.org/r/20210421185611.GA105224@embeddedorSigned-off-by:Gustavo A.

During runtime-suspend of ufs host, the SCSI devices are already suspended and so are the queues associated with them. However, the ufs host sends SSU (START_STOP_UNIT) to the wlun during runtime-suspend. During the process blk_queue_enter() checks if the queue is not in suspended state. If so, it waits for the queue to resume, and never comes out of it. Commit 52abca64 ("scsi: block: Do not accept any requests while suspended") adds the check to see if the queue is in suspended state in blk_queue_enter().
