2011-07-27[SCSI] dh_rdac: Use WWID from C8 page instead of Subsystem id from C4 page ↵Chandra Seetharaman
to identify storage rdac hardware handler uses "Subsystem Identifier" from C4 inquiry page to uniquely identify a storage. The problem with that is that if any any of the bytes are non-ascii, subsys_id will all be spaces (hex 0x20). This creates lot of problems especially when there are multiple rdac storages are connected to the server.

2011-07-27[SCSI] scsi_lib: pause between error retriesJames Smart
During cable pull tests on our 16G FC adapter, we are seeing errors, typically reads to close targets, which fail due to CRC or framing errors caused by the cable being pull (return status DID_ERROR). The adapter detects the error on one of the first frames received, marks the FC exchange as dead (further frames go to bit bucket) and signals the host of the error. This action is so quick, and coupled with fast host CPUs, creates a scenario in which the midlayer sees the failure and retries the io almost immediately. We've seen link traces with the retry on the link while the original i/o is still being processed by the target. We're also seeing the time window for the "link to pull-apart" and the physical interface to report disconnected to be in the few millisecond range. Which means, we're encountering scenarios where the full retry count is exhausted (all with error) by the midlayer before the link disconnect state is detected. We looked at 8G FC behavior and occasionally see the same behavior, but as the link was slower, it rarely could exhaust all retries before the link reported disconnect. What is needed is a slight delay between io retries due to DID_ERROR to cover this error. It is inappropriate to put this delay in the driver, as the error is indistinguishable from other link-related errors, nor does the driver track whether the io is a retry or not. This is also easier than tracking between-io-error bursts that are seen in this scenario. The patch below updates the retry path so that it inserts a delay as if the target was busy. The busy delay is on the order of 6ms. This delay is sufficient to ensure the link down condition is reported before the retry count is exhausted (at most 1 retry is seen).

2011-07-21[SCSI] fix crash in scsi_dispatch_cmd()James Bottomley
USB surprise removal of sr is triggering an oops in scsi_dispatch_command(). What seems to be happening is that USB is hanging on to a queue reference until the last close of the upper device, so the crash is caused by surprise remove of a mounted CD followed by attempted unmount. The problem is that USB doesn't issue its final commands as part of the SCSI teardown path, but on last close when the block queue is long gone. The long term fix is probably to make sr do the teardown in the same way as sd (so remove all the lower bits on ejection, but keep the upper disk alive until last close of user space). However, the current oops can be simply fixed by not allowing any commands to be sent to a dead queue. Cc: stable@kernel.org Signed-off-by: James Bottomley <JBottomley@Parallels.com>

2011-07-21[SCSI] bnx2i: Fixed kernel panic due to illegal usage of sc->request->cpuEddie Wai
A kernel panic was observed when passing the sc->request->cpu = -1 to retrieve the per_cpu variable pointer: #0 [ffff880011203960] machine_kexec at ffffffff81022bc3 #1 [ffff8800112039b0] crash_kexec at ffffffff81088630 #2 [ffff880011203a80] __die at ffffffff8139ea20 #3 [ffff880011203aa0] no_context at ffffffff8102f3a7 #4 [ffff880011203ae0] __bad_area_nosemaphore at ffffffff8102f665 #5 [ffff880011203ba0] retint_signal at ffffffff8139dd1f #6 [ffff880011203cc8] bnx2i_indicate_kcqe at ffffffffa03dc4f2 #7 [ffff880011203da8] service_kcqes at ffffffffa03cb04f #8 [ffff880011203e68] cnic_service_bnx2x_kcq at ffffffffa03cb14a #9 [ffff880011203e88] cnic_service_bnx2x_bh at ffffffffa03cb1b3 The problem lies in the slow path sg_io (and perhaps sg_scsi_ioctl) call to blk_get_request->get_request/wait->blk_alloc_request->blk_rq_init which re-initializes the request->cpu to -1. There is no assignment for cpu from that to the request_fn call to low level drivers. When this happens, the sc->request->cpu will be using the init value of -1. This will create a kernel panic when it hits bnx2i because the code refers it to get the per_cpu variables ptr. This change is to put in a guard against that and also for cases when bio affinity/queue completion to the same cpu is not enabled. In those cases, the request->cpu will remain a -1 also. This bug was created from commit: b5cf6b63f73abdc051035f0050b367beeb2ef94c For the case when the blk layer did not setup the request->cpu, bnx2i will complete the sc with the current CPU of the thread.
