We have seen two cases where VPD on an emulex card has been incorrect and we end up walking off the end of memory. It looks like someone made an update (increased the length of a string) without increasing the Length field. Then we do: Length -= (3+i); And since Length is unsigned it becomes very large and we loop forever in the encapsulating: while (Length > 0) { If we make Length signed then we fall out of the loop and proceed on. Its important to note we have only seen this in the lab and it may be the only two cases of this in existence, but since the rest of the code has been written to be resilient against bad VPD we may as well fix this too.

There is some residual cleanup of the last series of patches and the need to bump the revision number to draw the line in the sand. The cmd->SCp.phase is set in the aac_valid_context routine, then set again to the same value following it's return. The cmd->scsi_done is set twice in the aac_queuecommand routine. Free up the scsidev FILO in aac_probe_container as it is not needed further down the function in any case. Improve the efficiency of the abort handler kernel print parameters. Bump revision number of driver to approximate the equivalent in the Adaptec supplied version. Signed-off-by:

Captured a panic on an older kernel where an application issuing commands via sg was sending requests that lacked a request_buffer, thus the buffer pointer used in aac_internal_transer was NULL. The application was fixed closing the issue, but felt it was advised to immunize the driver against the eventuality. Signed-off-by:

The #ifdef MODULE around the export of scsi_complete_async_scans() which is the API the scsi_wait_scan module uses is incorrect and causes the symbol to be undefined in certain circumstances leading to a build failure. Remove the defines. Signed-off-by:

Implement SBC START/STOP management. sdev->mange_start_stop is added. When it's set to one, sd STOPs the device on suspend and shutdown and STARTs it on resume. sdev->manage_start_stop defaults is in sdev instead of scsi_disk cdev to allow ->slave_config() override the default configuration but is exported under scsi_disk sysfs node as sdev->allow_restart is. When manage_start_stop is zero (the default value), this patch doesn't introduce any behavior change. Signed-off-by:

This address the issue of VMWare guest OS being remounted as read-only becuase the underlying device was held busy too long and at the same time address Engenio MPP driver concerns over infinite retries. This patch removes the code that snoops the SAM STATUS on busy, which would be returning DID_BUS_BUSY, instead we return the status as is. Retry hanlding seems to be properly handled in scsi_softirq_done, where a busy sam status would only occurr for the time specified by (cmd->allowed +1) * cmd->timeout_per_command. 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, 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:

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:

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: -

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).
