2008-10-23PCI: fix ARI code to be compatible with mixed ARI/non-ARI systemsZhao, Yu1-8/+13
The original ARI support code has a compatibility problem with non-ARI devices. If a device doesn't support ARI, turning on ARI forwarding on its upper level bridge will cause undefined behavior. This fix turns on ARI forwarding only when the subordinate devices support it.

2008-10-23PCI hotplug: cpqphp: fix kernel NULL pointer dereferenceKenji Kaneshige1-1/+1
The following patch fixes the regression in 2.6.27 that causes kernel NULL pointer dereference at cpqphp driver probe time. This patch should be backported to the .27 stable series. Seems to have been introduced by f46753c5e354b857b20ab8e0fe7b2579831dc369. The root cause of this problem seems that cpqphp driver calls pci_hp_register() wrongly. In current implementation, cpqphp driver passes 'ctrl->pci_dev->subordinate' as a second parameter for pci_hp_register(). But because hotplug slots and it's hotplug controller (exists as a pci funcion) are on the same bus, it should be 'ctrl->pci_dev->bus' instead.

2008-10-23tcp: Restore ordering of TCP options for the sake of inter-operabilityIlpo Järvinen1-6/+17
This is not our bug! Sadly some devices cannot cope with the change of TCP option ordering which was a result of the recent rewrite of the option code (not that there was some particular reason steming from the rewrite for the reordering) though any ordering of TCP options is perfectly legal. Thus we restore the original ordering to allow interoperability with/through such broken devices and add some warning about this trap. Since the reordering just happened without any particular reason, this change shouldn't cost us anything. There are already couple of known failure reports (within close proximity of the last release), so the problem might be more wide-spread than a single device. And other reports which may be due to the same problem though the symptoms were less obvious. Analysis of one of the case revealed (with very high probability) that sack capability cannot be negotiated as the first option (SYN never got a response).

This was another merge problem that wasn't a data conflict, but due to independent changes in two branches that just didn't work together. The pcc-acpi staging driver used acpi_driver_data(device) = hotkey; to set driver data, but the ACPI merge made that invalid in commit db89b4f0dbab837d0f3de2c3e9427a8d5393afa3 ("ACPI: catch calls of acpi_driver_data on pointer of wrong type"), and now you're supposed to just do. device->driver_data = hotkey; instead.

2008-10-23[SCSI] lib: string_get_size(): don't hang on zero; no decimals on exactH. Peter Anvin1-15/+19
We would hang forever when passing a zero to string_get_size(). Furthermore, string_get_size() would produce decimals on a value small enough to be exact. Finally, a few formatting issues are inconsistent with standard SI style guidelines. - If the value is less than the divisor, skip the entire rounding step. This prints out all small values including zero as integers, without decimals. - Add a space between the value and the symbol for the unit, consistent with standard SI practice. - Lower case k in kB since we are talking about powers of 10. - Finally, change "int" to "unsigned int" in one place to shut up a gcc warning when compiling the code out-of-kernel for testing.

2008-10-23[SCSI] sd: remove command-size switching codeAlan Stern1-9/+0
This patch (as1138) removes from sd.c some old code for switching from 10-byte commands to 6-byte commands. This code is redundant -- the switching for READ and WRITE is already handled in scsi_io_completion() and the switching for MODE SENSE is already handled in scsi_mode_sense(). (There is no comparable switch for MODE SELECT, but I doubt one is needed.) Furthermore the other handlers do a better job; they check for appropriate ASC and ASCQ values before blindly switching the size. The code in sd.c is known to cause problems with some devices by switching when it shouldn't.

2008-10-23[SCSI] sd: Fix handling of NO_SENSE check conditionJamie Wellnitz1-1/+9
The current handling of NO_SENSE check condition is the same as RECOVERED_ERROR, and assumes that in both cases, the I/O was fully transferred. We have seen cases of arrays returning with NO_SENSE (no error), but the I/O was not completely transferred, thus residual set. Thus, rather than return good_bytes as the entire transfer, set good_bytes to 0, so that the midlayer then applies the residual in calculating the transfer, and for sd, will fail the I/O and fall into a retry path.

2008-10-23[SCSI] export busy state via q->lld_busy_fn()Kiyoshi Ueda1-0/+32
This patch implements q->lld_busy_fn() for scsi mid layer to export its busy state for request stacking drivers. For efficiency, no lock is taken to check the busy state of shost/starget/sdev, since the returned value is not guaranteed and may be changed after request stacking drivers call the function, regardless of taking lock or not. When scsi can't dispatch I/Os anymore and needs to kill I/Os (e.g. !sdev), scsi needs to return 'not busy'. Otherwise, request stacking drivers may hold requests forever.

2008-10-23[SCSI] scsi_dh: Initialize path state to be passive when path is not ownedChandra Seetharaman1-0/+3
Set the path state to be passive when we learn that the controller does not own the path to the LUN. This will avoid sending even a single i/o thru the passive path at the probe time.

The problem is essentially caused by us eating UNIT_ATTENTION conditions in scsi_test_unit_ready(). Fix by updating the ->changed flag when this happens if the media is removable.
