| * [SCSI] sg: fix q->queue_lock on scsi_error_handler pathFUJITA Tomonori2009-04-031-3/+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().

| * [SCSI] libiscsi: fix iscsi pool error pathJean Delvare2009-04-031-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] fcoe, libfcoe: Add support for FIP. FCoE discovery and keep-alive.Joe Eykholt2009-04-033-136/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] fcoe: create/destroy fcoe Rx threads on CPU hotplug eventsRobert Love2009-04-031-47/+199
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for dynamically created Rx threads upon CPU hotplug events. There were existing synchronization problems that this patch attempts to resolve. The main problem had to do with fcoe_rcv() running in a different context than the hotplug notifications. This opened the possiblity that fcoe_rcv() would target a Rx thread for a skb. However, that thread could become NULL if the CPU was made offline. This patch uses the Rx queue's (a skb_queue) lock to protect the thread it's associated with and we use the 'thread' member of the fcoe_percpu_s to determine if the thread is ready to accept new skbs. The patch also attempts to do a better job of cleaning up, both if hotplug registration fails as well as when the module is removed.

| * [SCSI] fix recovered error handlingJames Bottomley2009-04-033-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a problem with recovered error handling in that any command which goes down as BLOCK_PC but which returns a sense code of RECOVERED ERROR gets completed with -EIO. For actual SG_IO commands, this doesn't matter at all, since the error return code gets dropped in favour of req->errors which contain the SCSI completion code. However, if this command is part of the block system, then it will pay attention to the returned error code. In particularly if a SYNCHRONIZE CACHE from a barrier command completes with RECOVERED ERROR, the resulting -EIO on the barrier causes block to error the request and return it to the filesystem. Fix this by converting the -EIO for recovered error to zero, plus remove the printing of this from sd and sr so the message isn't double printed.

| * [SCSI] aic7xxx: leaves timer running on init failureHannes Reinecke2009-04-032-10/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | aic79xx leaves timers inserted when ahd_init() (which inserts two timers at its very end) succeeds but ahd_pci_map_int() fails. In this case ahd->init_level gets incremented to 5 only when that function succeeds, but ahd_free() calls ahd_shutdown() only when ahd->init_level == 5, and ahd_shutdown() is where the timers get removed. Since the freeing of the IRQ is not controlled by ahd->init_level, we should increment init_level prior to calling ahd_pci_map_int().

| | | | | | | | | | | | | | | | | | | | | | | | Firmware semantics changed for 24xx and above ISPs in their handling of the specified execution-throttle passed during firmware initialization. The original codes use of a theoretical maximum (0xffff, as carried over from earlier ISPs) could in fact act as a throttle in some circumstances. Now set the value based of the firmware's own 'resource' (exchange IOCBs) capabilities.

| | | | | | | | | | | | | | | | | | | | | | | | The original code to 'resize request-queues' based on iocb-counts and employed during early ISP23xx testing was too overly-pessimistic with regards to latencies in the firmware pulling requests. Recent ISPs can easily keep up processing a stream of commands from an abbreviated (effectively, half the original size) queue.
