Removed all the mutex's for ioc->tm_cmds.mutex, then created one single mutex inside the function mpt2sas_scsih_issue_tm. This is the single function used when sending task management. Also the sanity checks required for scsi mid layer escalation were moved to inside the same function because these checks need to be done while the mutex is held. The ioc->tm_cmds.mutex inside the IOCTL branch is really not required since there is another mutex in this code called for ctl_cmds handling this sync.

bug fix in the handling of the internal device reset event The reason code check in scsih_sas_device_status_change_event never evaluates as true for internal device reset, hence driver never quiesce s IO when firmware is sending a device reset. The fix is to change the evaluate to: if (event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET && event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET) return; Signed-off-by: NKashyap Desai <kashyap.desai@lsi.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

external host not connecting after controller reboot: The problem is : devices are not coming back after having the cable disconnected then reconnected. The problem is because the driver/firmware device removal handshake is failing. Due to this failure, the controller firmware is not sending out device add events when the target is reconnected. This is root caused to a race in the driver/firmware device removal algorithm. There is duplicate code in both interrupt and user context; where target reset is being issue from user context path while sas_iounit_control(OP_REMOVE) is being sent from interrupt context. An active target_reset will fail the OP_REMOVE. To fix this problem, the duplicate code has been removed from user context path.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The driver hangs when doing `rmmod mpt2sas` if there are any IR volumes present.The hang is due the scsi midlayer trying to access the IR volumes after the driver releases controller resources. Perhaps when scsi_remove_host is called,the scsi mid layer is sending some request. This doesn't occur for bare drives becuase the driver is already reporting those drives deleted prior to calling mpt2sas_base_detach. To solve this issue, we need to delete the volumes as well.

Added command line option and shost sysfs attribute called mpt2sas_fwfault_debug. When enduser writes a "1" to this parameter, this will enable support in the driver for debugging firmware timeout related issues. This handling was added in three areas (a) scsi error handling callback called task_abort, (b) IOCTL interface, and (c) other timeouts that result in diag resets, such as manufacturing config pages. When this support is enabled, the driver will provide dump_stack to console, halt controller firmware, and panic driver. The end user probably would want to setup serial console redirection so the dump stack can be seen. Here are the three methods for enable this support: (a) # insmod mpt2sas.ko mpt2sas_fwfault_debug=1 (b) # echo 1 > /sys/module/mpt2sas/parameters/mpt2sas_fwfault_debug (c) # echo 1 > /sys/class/scsi_host/host#/fwfault_debug (where # is the host number) Signed-off-by: NKashyap Desai <kashyap.desai@lsi.com> Signed-off-by: NEric Moore <Eric.moore@lsi.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

The existing implementation will stop processing futher device adds when a expander delete arrives on top of add expander add. Due to a sanity check in the driver, the devices there were not added, were never handshaked to firmware with the device removal handshake protocal.

The device driver was not handling updating device handles in all cases across diag resets. To fix this issue, the driver is converted to using sas address instead of handle as a lookup reference to the parent expander or sas_host. Also, for both expanders and sas host, the phy handle will be one unique handle. In the sas host case, the phy handle can be different for every phy, so the change is to set the handle to the handle of the first phy; every phy will be one single sas address(phy 0) instead of a different sas address for every phy(previous implementation). So making one consistent sas address for all the direct attachedports to the sas host, will make it better user experience when using udev /dev/disk/by-path dev nodes Signed-off-by: NKashyap Desai <kashyap.desai@lsi.com> Signed-off-by: NEric Moore <Eric.moore@lsi.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

The mpt2sas_base_get_smid function is for requesting internal commands. 3) Added new function _base_get_cb_idx to obtain the callback index from one of the three pools of request message frames. 4) Removed wrapper functions _scsih_scsi_lookup_set and _scsih_scsi_lookup_getclear. These were removed because this handling was moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid. 5) The function mpt2sas_base_free_smid is modified so the request message frames are put back on one of the three pools of request message frames.
