| * [SCSI] aacraid: READ_CAPACITY_16 shouldn't trust allocation length in cdbFUJITA Tomonori2008-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When aacraid spoofs READ_CAPACITY_16, it assumes that the data length in the sg list is equal to allocation length in cdb. But sg can put any value in scb so the driver needs to check both the data length in the sg list and allocation length in cdb. If allocation length is larger than the response length that the driver expects, it clears the data buffer in the sg list to zero but it doesn't need to do. Just setting resid is fine.

| | | | | | | | | | | | | | | | | | | | | | Add new option MT_ST_SILI to enable setting the SILI bit in reads in variable block mode.

Avoiding the REQUEST SENSE command for every block speeds up some real applications considerably.

* | libata: replace tf_read with qc_fill_rtf for non-SFF driversTejun Heo2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all SFF stuff is separated out of core layer, core layer doesn't call ops->tf_read directly. It gets called only via ops->qc_fill_rtf() for non-SFF drivers. This patch directly implements private ops->qc_fill_rtf() for non-SFF controllers and kill ops->tf_read(). This is much cleaner for non-SFF controllers as some of them have to cache SFF register values in private data structure and report the cached values via ops->tf_read(). Also, ops->tf_read() gets nasty for controllers which don't have clear notion of TF registers when operation is not in progress. As this change makes default ops->qc_fill_rtf unnecessary, move ata_sff_qc_fill_rtf() form ata_base_port_ops to ata_sff_port_ops where it belongs. Signed-off-by: Tejun Heo <htejun@gmail.com>
* | libata: add qc_fill_rtf port operationTejun Heo2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On command completion, ata_qc_complete() directly called ops->tf_read to fill qc->result_tf. This patch adds ops->qc_fill_rtf to replace hardcoded ops->tf_read usage. ata_sff_qc_fill_rtf() which uses ops->tf_read to fill result_tf is implemented and set in ata_base_port_ops and other ops tables which don't inherit from ata_base_port_ops, so this patch doesn't introduce any behavior change. ops->qc_fill_rtf() is similar to ops->sff_tf_read() but can only be called when a command finishes. As some non-SFF controllers don't have TF registers defined unless they're associated with in-flight commands, this limited operation makes life easier for those drivers and help lifting SFF assumptions from libata core layer.

* | libata: make reset related methods proper port operationsTejun Heo2008-04-17
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently reset methods are not specified directly in the ata_port_operations table. If a LLD wants to use custom reset methods, it should construct and use a error_handler which uses those reset methods. It's done this way for two reasons. First, the ops table already contained too many methods and adding four more of them would noticeably increase the amount of necessary boilerplate code all over low level drivers. Second, as ->error_handler uses those reset methods, it can get confusing. ie. By overriding ->error_handler, those reset ops can be made useless making layering a bit hazy. Now that ops table uses inheritance, the first problem doesn't exist anymore. The second isn't completely solved but is relieved by providing default values - most drivers can just override what it has implemented and don't have to concern itself about higher level callbacks. In fact, there currently is no driver which actually modifies error handling behavior. Drivers which override ->error_handler just wraps the standard error handler only to prepare the controller for EH. I don't think making ops layering strict has any noticeable benefit. This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and their PMP counterparts propoer ops. Default ops are provided in the base ops tables and drivers are converted to override individual reset methods instead of creating custom error_handler. * ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs aren't accessible. sata_promise doesn't need to use separate error_handlers for PATA and SATA anymore. * softreset is broken for sata_inic162x and sata_sx4. As libata now always prefers hardreset, this doesn't really matter but the ops are forced to NULL using ATA_OP_NULL for documentation purpose. * pata_hpt374 needs to use different prereset for the first and second PCI functions. This used to be done by branching from hpt374_error_handler(). The proper way to do this is to use separate ops and port_info tables for each function. Converted.

* scsi: fix sense_slab/bio swapping livelockHugh Dickins2008-04-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 2.6.25-rc7, I've been seeing an occasional livelock on one x86_64 machine, copying kernel trees to tmpfs, paging out to swap. Signature: 6000 pages under writeback but never getting written; most tasks of interest trying to reclaim, but each get_swap_bio waiting for a bio in mempool_alloc's io_schedule_timeout(5*HZ); every five seconds an atomic page allocation failure report from kblockd failing to allocate a sense_buffer in __scsi_get_command. __scsi_get_command has a (one item) free_list to protect against this, but rc1's [SCSI] use dynamically allocated sense buffer de25deb18016f66dcdede165d07654559bb332bc upset that slightly. When it fails to allocate from the separate sense_slab, instead of giving up, it must fall back to the command free_list, which is sure to have a sense_buffer attached. Either my earlier -rc testing missed this, or there's some recent contributory factor. One very significant factor is SLUB, which merges slab caches when it can, and on 64-bit happens to merge both bio cache and sense_slab cache into kmalloc's 128-byte cache: so that under this swapping load, bios above are liable to gobble up all the slots needed for scsi_cmnd sense_buffers below. That's disturbing behaviour, and I tried a few things to fix it. Adding a no-op constructor to the sense_slab inhibits SLUB from merging it, and stops all the allocation failures I was seeing; but it's rather a hack, and perhaps in different configurations we have other caches on the swapout path which are ill-merged. Another alternative is to revert the separate sense_slab, using cache-line-aligned sense_buffer allocated beyond scsi_cmnd from the one kmem_cache; but that might waste more memory, and is only a way of diverting around the known problem. While I don't like seeing the allocation failures, and hate the idea of all those bios piled up above a scsi host working one by one, it does seem to emerge fairly soon with the livelock fix. So lacking better ideas, stick with that one clear fix for now.

| * [SCSI] iscsi class: regression - fix races with state manipulation and ↵Mike Christie2008-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | blocking/unblocking For qla4xxx, we could be starting a session, but some error (network, target, IO from a device that got started, etc) could cause the session to fail and curring the block/unblock and state manipulation could race with each other. This patch just has those operations done in the single threaded iscsi eh work queue, so that way they are serialized.

| * [SCSI] qla4xxx: regression - add start scan calloutMike Christie2008-03-05
| | | | | | | | | | | | | | | | | | | | We are seeing EXIST errors from sysfs during device addition. We need a start scan callout so we do not start scanning sessions found during hba setup, before the async scsi scan code is ready.

| * [SCSI] qla4xxx: fix host reset dpc raceMike Christie2008-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The host reset callout could be starting to reset the hba at the same time the dpc thread is. This creates lots of problems because they both want to do wierd things with the firmware and interrupts, etc. This patch just has the host reset function fully shutdown the dpc thread before resetting the hba. This patch also moves the setting of the session online bit to fix a potential race with the dpc thread and iscsi recovery thread.
