2009-03-12RDMA/nes: Don't allow userspace QPs to use STag zeroFaisal Latif
STag zero is a special STag that allows consumers to access any bus address without registering memory. The nes driver unfortunately allows STag zero to be used even with QPs created by unprivileged userspace consumers, which means that any process with direct verbs access to the nes device can read and write any memory accessible to the underlying PCI device (usually any memory in the system). Such access is usually given for cluster software such as MPI to use, so this is a local privilege escalation bug on most systems running this driver. The driver was using STag zero to receive the last streaming mode data; to allow STag zero to be disabled for unprivileged QPs, the driver now registers a special MR for this data.

2009-03-12acer-wmi: fix regression in backlight detectionMichael Spang
Currently we disable the Acer WMI backlight device if there is no ACPI backlight device. As a result, we end up with no backlight device at all. We should instead disable it if there is an ACPI device, as the other laptop drivers do. This regression was introduced in febf2d9 ("Acer-WMI: fingers off backlight if video.ko is serving this functionality"). Each laptop driver with backlight support got a similar change around febf2d9. The changes to the other drivers look correct; see e.g. a598c82f for a similar but correct change. The regression is also in 2.6.28.

Commit 47a8b0cc (Enable PCIe AER only after checking firmware support) wants to walk the PCI bus in the remove path to disable AER, and calls pci_walk_bus for downstream bridges. Unfortunately, in the remove path, we remove devices and bridges in a depth-first manner, starting with the furthest downstream bridge and working our way backwards. The furthest downstream bridges will not have a dev->subordinate, and we hit a NULL deref in pci_walk_bus. Check for dev->subordinate first before attempting to walk the PCI hierarchy below us.

2009-03-12PCI: Add PCI quirk to disable L0s ASPM state for 82575 and 82598Alexander Duyck
This patch is intended to disable L0s ASPM link state for 82598 (ixgbe) parts due to the fact that it is possible to corrupt TX data when coming back out of L0s on some systems. The workaround had been added for 82575 (igb) previously, but did not use the ASPM api. This quirk uses the ASPM api to prevent the ASPM subsystem from re-enabling the L0s state. Instead of adding the fix in igb to the ixgbe driver as well it was decided to move it into a pci quirk. It is necessary to move the fix out of the driver and into a pci quirk in order to prevent the issue from occuring prior to driver load to handle the possibility of the device being passed to a VM via direct assignment.

f75375_probe calls i2c_get_clientdata to initialize the data pointer, but there isn't yet any client data to get, and the value is never used before the variable is assigned a new value seven lines later. The call doesn't hurt anything and wastes only a couple of cycles. The reason to fix it is because this module serves as an example to hackers writing new hwmon drivers, and this part of the example is confusing.

2009-03-11radeonfb/aty128fb: Disable broken early resume hook for PowerBooksBenjamin Herrenschmidt
radeonfb and aty128fb have a special hook called by the PowerMac platform code very very early on resume from sleep to bring the screen back. This is useful for debugging wakup problems, but unfortunately, this also became a source of problems of its own. The hook is called extremely early, with interrupts still off, and the code path involved with that code nowadays rely on things like taking mutexes, GFP_KERNEL allocations, etc... In addition, the driver now relies on the PCI core to restore the standard config space before calling resume which doesn't happen with this early code path. I'm keeping the code in but commented out along with a fixup call to pci_restore_state(). The reason is that I still want to make it easy to re-enable temporarily to track wake up problems, and it's possible that I can revive it at some stage if we make sleeping things save to call in early resume using a system state. In the meantime, this should fix several reported regressions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-03-11hvc_console: Remove tty->low_latency on pseries backendsBenjamin Herrenschmidt
The hvcs and hvsi backends both set tty->low_latency to one, along with more or less scary comments regarding bugs or races that would happen if not doing so. However, they also both call tty_flip_buffer_push() in conexts where it's illegal to do so since some recent tty changes (or at least it may have been illegal always but it nows blows) when low_latency is set (ie, hard interrupt or with spinlock held and irqs disabled). This removes the setting for now to get them back to working condition, we'll have to address the races described in the comments separately if they are still an issue (some of this might have been fixed already).

2009-03-10i810: fix kernel crash fix when struct fb_var_screeninfo is suppliedSamuel CUELLA
Prevent the kernel from being crashed by a divide-by-zero operation when supplied an incorrectly filled 'struct fb_var_screeninfo' from userland. Previously i810_main.c:1005 (i810_check_params) was using the global 'yres' symbol previously defined at i810_main.c:145 as a module parameter value holder (i810_main.c:2174). If i810fb is compiled-in or if this param doesn't get a default value, this direct usage leads to a divide-by-zero at i810_main.c:1005 (i810_check_params). The patch simply replace the 'yres' global, perhaps undefined symbol usage by a given parameter structure lookup. This problem occurs with directfb, mplayer -vo fbdev, SDL library.

2009-03-10mm: get_nid_for_pfn() returns intRoel Kluin
get_nid_for_pfn() returns int Presumably the (nid < 0) case has never happened. We do know that it is happening on one system while creating a symlink for a memory section so it should also happen on the same system if unregister_mem_sect_under_nodes() were called to remove the same symlink. The test was actually added in response to a problem with an earlier version reported by Yasunori Goto where one or more of the leading pages of a memory section on the 2nd node of one of his systems was uninitialized because I believe they coincided with a memory hole. That earlier version did not ignore uninitialized pages and determined the nid by considering only the 1st page of each memory section. This caused the symlink to the 1st memory section on the 2nd node to be incorrectly created in /sys/devices/system/node/node0 instead of /sys/devices/system/node/node1. The problem was fixed by adding the test to skip over uninitialized pages. I suspect we have not seen any reports of the non-removal of a symlink due to the incorrect declaration of the nid variable in unregister_mem_sect_under_nodes() because - systems where a memory section could have an uninitialized range of leading pages are probably rare. - memory remove is probably not done very frequently on the systems that are capable of demonstrating the problem. - lingering symlink(s) that should have been removed may have simply gone unnoticed.

If userspace passes an object list with the same object appearing more than once, we end up hitting the BUG_ON() in i915_gem_object_set_to_gpu_domain() as it gets called a second time for the same object. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Eric Anholt <eric@anholt.net>

2009-03-10video: deferred io cleanup fix for sh_mobile_lcdcfbMagnus Damm
Fix deferred io cleanup patch in the sh_mobile_lcdcfb driver. If probe() fails early the sh_mobile_lcdc_stop() function will be called to clean up deferred io. This patch modifies the code to only call fb_deferred_io_cleanup() after deferred io has been initialized. With this patch applied we no longer hit BUG_ON() inside fb_deferred_io_cleanup(). Triggers on a Migo-R with the SYS QVGA panel board unmounted. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-03-09Revert "[CPUFREQ] Disable sysfs ui for p4-clockmod."Dave Jones
This reverts commit e088e4c9cdb618675874becb91b2fd581ee707e6. Removing the sysfs interface for p4-clockmod was flagged as a regression in bug 12826. Course of action: - Find out the remaining causes of overheating, and fix them if possible. ACPI should be doing the right thing automatically. If it isn't, we need to fix that. - mark p4-clockmod ui as deprecated - try again with the removal in six months. It's not really feasible to printk about the deprecation, because it needs to happen at all the sysfs entry points, which means adding a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

2009-03-09lguest: fix for CONFIG_SPARSE_IRQ=yRusty Russell
Impact: remove lots of lguest boot WARN_ON() when CONFIG_SPARSE_IRQ=y We now need to call irq_to_desc_alloc_cpu() before set_irq_chip_and_handler_name(), but we can't do that from init_IRQ (no kmalloc available). So do it as we use interrupts instead. Also means we only alloc for irqs we use, which was the intent of CONFIG_SPARSE_IRQ anyway.
