The patch [SCSI] SCSI core kmalloc2kzalloc Has an incorrect piece in sr_ioctl.c; it changes buffer from kmalloc to kzalloc, but then removes the clearing of the stack variable struct packet_command. This, in turn leaves rubbish in the sense pointer which the sr_do_ioctl() command then happily writes to ... oops. Thanks to Mike Christie <michaelc@cs.wisc.edu> for spotting this.

Be warned, that beyond compiling, and checking that the new module doesn't immediately blow up, there hasn't yet been a lot of testing. But this should allow you to comment on the changes, and move forward with dropping scsi_request from the kernel code. Signed-off-by:

Protect NPL lists with host lock Symptoms: lpfc_findnode_rpi and lpfc_findnode_did can be called outside of the discovery thread context. We have to iterate through the NPL lists under the host lock and all add/del operations on those lists have to be done under host lock. Signed-off-by:

Fix deadlock in lpfc_fdmi_tmo_handler lpfc_fdmi_tmo_handler was calling lpfc_fdmi_cmd with the host_lock held. lpfc_fdmi_cmd assumes the host_lock is released as it calls functions that acquire the host_lock. lpfc_fdmi_tmo_handler acquired the host_lock to protect access to work_hba_events. This was already checked in the worker thread so we can remove that code completely and remove access to the host_lock. Signed-off-by:

Fix performance when using multiple SLI rings Currently the driver allocates all of its SLI command and response ring entries to one primary ring. Other rings get little, or no, resources. Allow more resources to be given to ring 1 Signed-off-by:

PCI hrd_type should be obtained with pci_read_config_byte() macro Driver keys off of this field to report the proper adapter type. The pci subsystem explicitly clears the multiport bit in the copy of the field given the driver. Thus, to properly name the card, obtain it from config space. Signed-off-by:

Begin introducing the concept of sas remote devices that have an rphy embedded. The first one (this) is a simple end device. All that an end device really does is have port mode page parameters contained. The next and more complex piece will be expander remote devices. Signed-off-by:

aic94xx doesn't have a use for the bay or enclosure identifiers. Also, I think it's not going to need a get_linkerrors(), so wire up all of these exported properties as conditional on the underlying function support. Signed-off-by: -

This is the first half of a patch to add the generic domain validation to mptspi. It also creates a secondary "virtual" channel for raid component devices since these are now exported with no_uld_attach. What Eric and I would have really liked is to export all physical components on channel 0 and all raid components on channel 1. Unfortunately, this would result in device renumbering on platforms with mixed RAID/Physical devices which was considered unacceptable for userland stability reasons. Still to be done is to plug back the extra parameter setting and DV pieces on reset and hotplug. Signed-off-by: -

In order to use the new execute_in_process_context() API, you have to provide it with the work storage, which I do in SCSI in scsi_device and scsi_target, but which also means that we can no longer queue up the target reaps, so instead I moved the target to a state model which allows target_alloc to detect if we've received a dying target and wait for it to be gone. Hopefully, this should also solve the target namespace race. Signed-off-by:
