* Drivers: scsi: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-2/+2
| | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

|/ | | | | | | | | | | | | | | | | | | | | | max_queue_depth command line option to a very small value If the specified max_queue_depth setting is less than the expected number of internal commands, then driver will calculate the queue depth size to a negitive number. This negitive number is actually a very large number because variable is unsigned 16bit integer. So, the driver will ask for a very large amount of memory for message frames and resulting into oops as memory allocation routines will not able to handle such a large request. So, in order to limit this kind of oops, The driver need to set the max_queue_depth to a scsi mid layer's can_queue value. Then the overall message frames required for IO is minimum of either (max_queue_depth plus internal commands) or the IOC global credits.

So if the ioc->pfacts was read after a host reset, there would be a NULL pointer dereference. The routine _base_get_ioc_facts is called from context of host reset. The problem in _base_get_ioc_facts is the size of Mpi2IOCFactsReply is 64, whereas the sizeof "struct mpt2sas_facts" is 60, so there is a four byte overflow resulting from the memset. Also, there is memset in _base_get_port_facts using the incorrect structure, it should be "struct mpt2sas_port_facts" instead of Mpi2PortFactsReply.

| | | | | | | | | | | | | | | | | | | | | | | simultaneously another hard drive is hot unplugged Following the host reset, the firmware discovery is reassigning another hard drive in the topology to the same device handle as that device is getting hot removed. Until the driver device removal routine is called, there will be two hard drive with the matching device handle in the internal device link list. In the device removal routine, a separate function which moves the device from BLOCKED into OFFLINE state. Since this routine is passed with the device handle passed as input parameter, the routine will be traversing the internal device link list searching for matching device handle. This results in two devices with matching device handle, therefore both devices goes OFFLINE. To fix this issue,the input parameter is changed from device handle to SAS address, therefore only the device that is hot unplugged will be placed in OFFLINE state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | raid_device, and expander_device lists There were possible race conditions surrounding reading an object from the link list while from another context in the driver was removing it. The nature of this enhancement is to rearrange locking so the link lists are better protected. Change set: (1) numerous routines were rearranged so spin locks are held through the entire time a link list object is being read from or written to. (2) added new routines for object deletion from link list. Thus ensuring lock was held during the deletion of the link list object, then and memory for object freed outside the lock. The memory was freed outside the lock so driver had access to device object info which was required for notifying the scsi mid layer that a device was getting deleted. (3) added the ioc->blocking_handles parameter. This is a bitmask used to identify which devices need blocking when there is device loss. This was introduced so that lock can be held for the entire time traversing the link list objects, and the bitmask was set to indicate which device handles need blocking. Oustide the lock the ioc->blocking_handles bitmask is traversed, with the respective device handle the scsi mid layer is called for moving devices into blocking state.

There's also a new initcall_debug feature from Arjan which will print out quirk timing information to help identify slow quirks for fixing or refinement (Yinghai sent in a few patches to do just that once the new debug code landed). Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas. He's been a core PCI and Linux contributor for some time now, and has kindly volunteered to take over. I just don't feel I have the time for PCI review and work that it deserves lately (I've taken on some other projects), and haven't been as responsive lately as I'd like, so I approached Bjorn asking if he'd like to manage things. He's going to give it a try, and I'm confident he'll do at least as well as I have in keeping the tree managed, patches flowing, and keeping things stable."

Also moved the function scsi_scan_host(shost) to get called after the volumes on warp drive are reported to the OS. Otherwise by the time the (ioc->hide_drives) flags is set, the volumes on warp drive are reported to the OS already. Also modified the initialization of reply queues only in case of driver load time in the function _base_make_ioc_operational().

* | [SCSI] mpt2sas: Fix possible integer truncation of cpu_countRoland Dreier2011-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When computing reply_queue_count (the number of MSI-X vectors to use), the driver does ioc->reply_queue_count = min_t(u8, ioc->cpu_count, ioc->msix_vector_count); However, on a big machine, ioc->cpu_count could be outside the range that fits in a u8; eg a system with 256 CPUs will end up reply_queue_count set to 0. Fix this by calculating the minimum as ints and then letting the assignment to reply_queue_count handle integer demotion.
