It seems that most of the code in mptscsih_resume() doesn't do anything. This patch removes that code. Signed-off-by:

It looks like megaraid_sas at least needs this to throttle its commands as they begin to time out. The code keeps the existing transport template use of eh_timed_out (and allows the transport to override the host if they both have this callback). Signed-off-by: -

Received from Mark Salyzyn, This set of fixes improve error handling stability of the driver. A popular manifestation of the problems is an NULL pointer reference in the interrupt handler when referencing portions of the scsi command context, or in the scsi_done handling when an offlined device is referenced. The aacraid driver currently does not get notification of orphaned command completions due to devices going offline. The driver also fails to handle the commands that are finished by the error handler, and thus can complete again later at the hands of the adapter causing situations of completion of an invalid scsi command context. Test Unit Ready calls abort assuming that the abort was successful, but are not, and thus when the interrupt from the adapter occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to inform the aacraid FIB context that the interrupt service should merely release the driver resources and not complete the command up. We take advantage of this with the abort handler as well for select abortable commands. And we detect and react if a command that can not be aborted is currently still outstanding to the controller when reissued by the retry mechanism. Signed-off-by:

Received from Mark Salyzyn, The raw srb ioctl is supposed to be able to take packets with 32 and 64 bit virtual address SG elements, it did not handle the frames with 64 bit SG elements well when communicating with 64 bit DMA capable adapters, and it did not handle the 32 bit limited DMA adapters at all. The enclosed patch now handles all four quadrants (32 bit / 64 bit SG elements in SRB requests + 32 bit or 64 bit DMA capable adapters) This fix is required before Java based management applications in a 64 bit user space can submit raw srb requests to the array physical components via the ioctl mechanism, the allocated user memory pool on 64 bit machines under this environment forced the management software's hands to submit 64 bit user space virtual address SG elements in via the ioctl.

Received from Mark Salyzyn, This little patch removes the ',cid)' container identification argument from some of the functions. The argument is used in some cases as merely a debug helper and thus not used, and in others, the value can be quickly acquired from the scsi command in their single solitary use in the procedure rather than wasting resources on passing the argument in from above.

Received from Mark Salyzyn, Outstanding ioctl calls still have some problems with aborting cleanly in the face of a reset iop recovery action should the adapter ever enter into a Firmware Assert (BlinkLED) condition. The enclosed patch resolves some uncovered flawed handling. Signed-off-by:

Received from Mark Salyzyn, The aac_probe_container call blocks. This is an issue because it is called on occasion in the context of the queuecommand handler. Once in a blue moon this has resulted in a kernel panic sleeping during interrupt; or problems with some embedded system versions of the kernel that depend on queuecommand to not block. This ugly patch rewrites the aac_probe_container call into a new routine _aac_probe_container that is an asynchronous state machine to complete the series of operations. The legacy blocking aac_probe_container call used in other areas of the driver (during initialization scanning for all targets and in the separate hot-add/remove [aacraid] thread) merely issues _aac_probe_container and then simple spins calling schedule() waiting for completion.

Received from Mark Salyzyn, This patch is to resolve a namespace issue that will result from a patch expected in the future that adds a new interface; rationalized as correcting a long term issue where hw_fib, instead of hw_fib_va, refers to the virtual address space and hw_fib_pa refers to the physical address space. A small fragment of this patch also cleans up an unused variable that was close to the patch fragments. Signed-off-by:

Received from Mark Salyzyn, This patch updates the adapter restart function to deal with some adapters that have specific IOP reset needs. Since the code for restarting the adapter was in two places, changed over to utilizing a platform function in one place. Signed-off-by:

Some targets can return both valid data and sense information. Always update the request data_len from the SCSI command residual. Callers should interpret sense data to determine what parts of the data are valid in case of a CHECK CONDITION status. Signed-off-by:

tgt notifies a LLD of the failure with sense when it hits the user-space daemon bugs. However, tgt doesn't know anything about SCSI devices that initiators talks to. So it's impossible to send proper sense buffer (format and contents). This patch changes tgt not to notify a LLD of the failure with bogus sense. Instead, tgt just re-queues the failure command to the internal list so that it will be freed cleanly later on when the scsi_host is removed. Signed-off-by:

This patch updates the FC transport for all speeds identified in SM-HBA. Note: it does not sync the "bit" definitions, as that is actually insulated from user-space via the sysfs text string. (I could do it, but it does introduce a potential binary-incompatibility). Signed-off-by:

The module parameter, ql2xextended_error_logging, can now be set dynamically by writing to the following sysfs entry: /sys/module/qla2xxx/parameters/ql2xextended_error_logging This alleviates the need for the driver to be unloaded and reloaded in order to enable logging. Signed-off-by:

There's no need given, I/O has been quiesced, RISC interrupts have been disabled, and finally the RISC has been paused. Flash manipulation on ISP21xx, ISP22xx, and ISP23xx parts requires the RISC to go through a full reset to recover. Signed-off-by:

Currently scsi_wait_scan is only built modular if SCSI is modular. However, it's perfectly possible for a built in SCSI still to have modular drivers and thus need scsi_wait_scan as a module. Therefore, scsi_wait_scan should always be built as a module (unless the kernel doesn't support modules). Signed-off-by: -

The failure to map user-space pages leads to scsi command leak. It can happens mostly because of user-space daemon bugs (or OOM). This patch makes tgt just notify a LLD of the failure with sense when blk_rq_map_user() fails. Signed-off-by:

This patch simplify the way to notify LLDs of the command completion and addresses the following sense buffer problems: - can't handle both data and sense. - forces user-space to use aligned sense buffer tgt copies sense_data from userspace to cmnd->sense_buffer (if necessary), maps user-space pages (if necessary) and then calls host->transfer_response (host->transfer_data is removed).

scsi tgt breaks up a command into multple scatterlists if we cannot fit all the data in one. This was because the block rq helpers did not support large requests and because we can get a command of any old size so it is hard to preallocate pages for scatterlist large enough (we cannot really preallocate pages with the bio map user path). In 2.6.20, we added large request support to the block layer helper, blk_rq_map_user. And at LSF, we talked about increasing SCSI_MAX_PHYS_SEGMENTS for scsi tgt if we want to support really really :) large (greater than 256 * PAGE_SIZE in the worst mapping case) requests. The only target currently implemented does not even support the multiple scatterlists stuff and only supports smaller requests, so this patch just coverts scsi tgt to use blk_rq_map_user.

People do not read the README and seem to like to unselect the crc32c module even though iscsi_tcp selects it for them. This patch spits a error that tells the user that they really do need the module. Hopefully, we will get fewer people asking about this now. Signed-off-by:

Dave Miller meantioned that the data buffer in a past sense fixup patch was not gauranteed to be aligned properly for ia64. This patch has libiscsi use get_unalinged to make sure. There are a couple more places in the digest handling we may need to do this, but we are in the middle of fixing that code for big endien systems so just the sense access is fixed here.

This reverts commit d2487cb4. Russell King points out that it's obviously bogus, and I have to agree. Not only does "irq" not even exist in that scope, but we obviously need to free the irq that we actually requested, and that's IRQ_USB. Reported-by:
