8.3.1 Fixes/Changes : - Fix incorrect byte-swapping on word 4 of IOCB (data length) which caused LUNs to not be discovered on big-endian (e.g. PPC) - Remove a bad cast of MBslimaddr which loses the __iomem (sparse) - Make lpfc_debugfs_mask_disc_trc static (sparse) - Correct misspelled word BlockGuard in lpfc_logmsg.h comment - Replaced repeated code segment for canceling IOCBs from a list with a function call, lpfc_sli_cancel_iocbs(). - Increased HBQ buffers to support 40KB SSC sequences. - Added sysfs interface to update speed and topology parameter without link bounce. - Fixed bug with sysfs fc_host WWNs not being updated after changing the WWNs. - Check if the active mailbox is NULL in the beginning of the mailbox timeout handler - fixes panic in the mailbox timeout handler while running IO stress test - Fixed system panic in lpfc_pci_remove_one() due to ndlp indirect reference to phba through vport - Removed de-reference of scsi device after call to scsi_done() to fix panic in scsi completion path while accessing scsi device after scsi_done is called. - Fixed "Nodelist not empty" message when unloading the driver after target reboot test - Added LP2105 HBA model description - Added code to print all 16 words of unrecognized ASYNC events - Fixed memory leak in vport create + delete loop - Added support for handling dual error bit from HBA - Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb - Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node - Take NULL termintator into account when calculating available buffer space Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2009-04-27[SCSI] sg: return EFAULT for an invalid user addressFUJITA Tomonori1-5/+8
blk_rq_unmap_user() returns EFAULT if a program passes an invalid address to kernel (the kernel fails to copy data to user space). sg needs to pass the returned value to user space instead of ignoring it. Before the block layer conversion, sg returns EFAULT properly. This restores the old behavior.

2009-04-27[SCSI] sr: report more accurate drive status after closing the tray.Peter Jones1-0/+5
So, what's happening here is that the drive is reporting a sense of 2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and then we ask for the media event notification before checking that result at all. The check_media_event_descriptor() call isn't getting a check condition, but it's also reporting that the tray is closed and that there's no media. In actuality it doesn't yet know if there's media or not, but there's no way to express that in the media event status field. My current thought is that if it told us the device isn't yet ready, we should return that immediately, since there's nothing that'll tell us any more data than that reliably: Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2009-04-22driver synchronization: make scsi_wait_scan more advancedArjan van de Ven2-2/+11
There is currently only one way for userspace to say "wait for my storage device to get ready for the modules I just loaded": to load the scsi_wait_scan module. Expectations of userspace are that once this module is loaded, all the (storage) devices for which the drivers were loaded before the module load are present. Now, there are some issues with the implementation, and the async stuff got caught in the middle of this: The existing code only waits for the scsy async probing to finish, but it did not take into account at all that probing might not have begun yet. (Russell ran into this problem on his computer and the fix works for him) This patch fixes this more thoroughly than the previous "fix", which had some bad side effects (namely, for kernel code that wanted to wait for the scsi scan it would also do an async sync, which would deadlock if you did it from async context already.. there's a report about that on lkml): The patch makes the module first wait for all device driver probes, and then it will wait for the scsi parallel scan to finish.

2009-04-14Fix lpfc_parse_bg_err()'s use of do_div()David Howells1-1/+1
Fix lpfc_parse_bg_err()'s use of do_div(). It should be passing a 64-bit variable as the first parameter. However, since it's only using a 32-bit variable, it doesn't need to use do_div() at all, but can instead use the division operator. This deals with the following warnings: CC drivers/scsi/lpfc/lpfc_scsi.o drivers/scsi/lpfc/lpfc_scsi.c: In function 'lpfc_parse_bg_err': drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: comparison of distinct pointer types lacks a cast drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: right shift count >= width of type drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: passing argument 1 of '__div64_32' from incompatible pointer type Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-04-13PM/Hibernate: Wait for SCSI devices scan to complete during resumeRafael J. Wysocki2-4/+1
There is a race between resume from hibernation and the asynchronous scanning of SCSI devices and to prevent it from happening we need to call scsi_complete_async_scans() during resume from hibernation. In addition, if the resume from hibernation is userland-driven, it's better to wait for all device probes in the kernel to complete before attempting to open the resume device.

2009-04-03[SCSI] sg: fix q->queue_lock on scsi_error_handler pathFUJITA Tomonori1-3/+6
sg_rq_end_io() is called via rq->end_io. In some rare cases, sg_rq_end_io calls blk_put_request/blk_rq_unmap_user (when a program issuing a command has gone before the command completion; e.g. by interrupting a program issuing a command before the command completes). We can't call blk_put_request/blk_rq_unmap_user in interrupt so the commit c96952ed7031e7c576ecf90cf95b8ec099d5295a uses execute_in_process_context(). The problem is that scsi_error_handler() calls rq->end_io too. We can't call blk_put_request/blk_rq_unmap_user too in this path (we hold q->queue_lock). To avoid the above problem, in these rare cases, this patch always uses schedule_work() instead of execute_in_process_context().

Le lundi 30 mars 2009, Chris Wright a écrit : > q->queue could be ERR_PTR(-ENOMEM) which will break unwinding > on error. Make iscsi_pool_free more defensive. > Making the freeing of q->queue dependent on q->pool being set looks really weird (although it is correct at the moment. But this seems to be fixable in a much simpler way. With the benefit that only the error case is slowed down. In both cases we have a problem if q->queue contains an error value but it's not -ENOMEM. Apparently this can't happen today, but it doesn't feel right to assume this will always be true. Maybe it's the right time to fix this as well.

2009-04-03[SCSI] fcoe, libfcoe: Add support for FIP. FCoE discovery and keep-alive.Joe Eykholt3-136/+1366
FIP is the new standard way to discover Fibre-Channel Forwarders (FCFs) by sending solicitations and listening for advertisements from FCFs. It also provides for keep-alives and period advertisements so that both parties know they have connectivity. If the FCF loses connectivity to the storage fabric, it can send a Link Reset to inform the E_node. This version is also compatible with pre-FIP implementations, so no configured selection between FIP mode and non-FIP mode is required. We wait a couple seconds after sending the initial solicitation and then send an old-style FLOGI. If we receive any FIP frames, we use FIP only mode. If the old FLOGI receives a response, we disable FIP mode. After every reset or link up, this determination is repeated.

2009-04-03[SCSI] fcoe: removes default sw transport code file fcoe_sw.cVasu Dev3-533/+494
Moves only required code from fcoe_sw.c to libfcoe.c towards having just one source file for fcoe module, this gets rid off default sw transport code in a separate fcoe_sw.c file. Very minor renaming along this move, dropped _sw_ or _SW_ use in names and replaced them by _if_ as a auxiliary interface functions. Now some of these funcs can be removed or merged with other func after fcoe transport is gone, but that should be in another patch to keep this patch simple. Now the libfcoe.c file name for fcoe module doesn't go along well, so the libfcoe.c file renaming to fcoe.c as the only single fcoe module file is done in next patch to keep this patch clean and small for review.
