2010-02-26Remove EXPERIMENTAL from NFS_FSCACHEChristian Kujau1-2/+1
There's currently an open Ubuntu bug[0], with the intent to compile NFS_FSCACHE (and possibly AFS_FSCACHE, 9P_FSCACHE) into the standard Ubuntu kernel. However, since *_FSCACHE still depends on EXPERIMENTAL, this won't happen. As Arjan van de Ven pointed out[1], the EXPERIMENTAL flag doesn't mean that much any more, I propose the following patch to fs/nfs/Kconfig. I'd do the same for fs/9p/Kconfig and fs/afs/Kconfig, but as I did not test 9p or AFS, I feel it would not be appropriate for me to remove the flag.

2010-02-26dvb-core: Fix DoS bug in ULE decapsulation code that can be triggered by an ↵Ang Way Chuang1-0/+1
invalid Payload Pointer ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation has a bug that causes endless loop when Payload Pointer of MPEG2-TS frame is 182 or 183. Anyone who sends malicious MPEG2-TS frame will cause the receiver of ULE SNDU to go into endless loop. This patch was generated and tested against linux-2.6.32.9 and should apply cleanly to linux-2.6.33 as well because there was only one typo fix to dvb_net.c since v2.6.32. This bug was brought to you by modern day Santa Claus who decided to shower the satellite dish at Keio University with heavy snow causing huge burst of errors. We, receiver end, received Santa Claus's gift in the form of kernel bug. Care has been taken not to introduce more bug by fixing this bug, but please scrutinize the code for I always produces buggy code.

2010-02-26PM / Hibernate: Fix preallocating of memoryRafael J. Wysocki1-1/+1
The hibernate memory preallocation code allocates memory to push some user space data out of physical RAM, so that the hibernation image is not too large. It allocates more memory than necessary for creating the image, so it has to release some pages to make room for allocations made while suspending devices and disabling nonboot CPUs, or the system will hang due to the lack of free pages to allocate from. Unfortunately, the function used for freeing these pages, free_unnecessary_pages(), contains a bug that prevents it from doing the job on all systems without highmem. Fix this problem, which is a regression from the 2.6.30 kernel, by using the right condition for the termination of the loop in free_unnecessary_pages(). Signed-off-by: Rafael J.

2010-02-26PM: Allow SCSI devices to suspend/resume asynchronouslyRafael J. Wysocki2-0/+8
Set power.async_suspend for all SCSI devices, targets and hosts, so that they can be suspended and resumed in parallel with the main suspend/resume thread and possibly with other devices they don't depend on in a known way (i.e. devices which are not their parents or children). The power.async_suspend flag is also set for devices that don't have suspend or resume callbacks, because otherwise they would make the main suspend/resume thread wait for their "asynchronous" children (during suspend) or parents (during resume), effectively negating the possible gains from executing these devices' suspend and resume callbacks asynchronously.

2010-02-26USB: implement non-tree resume ordering constraints for PCI host controllersAlan Stern3-1/+135
This patch (as1331) adds non-tree ordering constraints needed for proper resume of PCI USB host controllers from hibernation. The main issue is that non-high-speed devices must not be resumed before the high-speed root hub, because it is the ehci_bus_resume() routine which takes care of handing the device connection over to the companion controller. If the device resume is attempted before the handover then the device won't be found and it will be treated as though it had disconnected. The patch adds a new field to the usb_bus structure; for each full/low-speed bus this field will contain a pointer to the companion high-speed bus (if one exists). It is used during normal device resume; if the hs_companion pointer isn't NULL then we wait for the root-hub device on the hs_companion bus. A secondary issue is that an EHCI controlller shouldn't be resumed before any of its companions. On some machines I have observed handovers failing if the companion controller is reinitialized after the handover. Thus, the EHCI resume routine must wait for the companion controllers to be resumed. The patch also fixes a small bug in usb_hcd_pci_probe(); an error path jumps to the wrong label, causing a memory leak.

Set power.async_suspend for all PCI devices and PCIe port services, so that they can be suspended and resumed in parallel with other devices they don't depend on in a known way (i.e. devices which are not their parents or children). This only affects the "regular" suspend and resume stages, which means in particular that the restoration of the PCI devices' standard configuration registers during resume will still be carried out synchronously (at the "early" resume stage).

2010-02-26PM: Allow device drivers to use dpm_wait()Rafael J. Wysocki2-0/+13
There are some dependencies between devices (in particular, between EHCI USB controllers and their OHCI/UHCI siblings) which are not reflected by the structure of the device tree. With synchronous suspend and resume these dependencies are taken into accout automatically, because the devices in question are always registered in the right order, but to meet these constraints with asynchronous suspend and resume the drivers of these devices will need to use dpm_wait() in their suspend/resume routines, so introduce a helper function allowing them to do that. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2010-02-26PM: Start asynchronous resume threads upfrontRafael J. Wysocki1-19/+24
It has been shown by testing that total device resume time can be reduced significantly (by as much as 50% or more) if the async threads executing some devices' resume routines are all started before the main resume thread starts to handle the "synchronous" devices. This is a consequence of the fact that the slowest devices tend to be located at the end of dpm_list, so their resume routines are started very late. Consequently, they have to wait for all the preceding "synchronous" devices before their resume routines can be started by the main resume thread, even if they are "asynchronous". By starting their async threads upfront we effectively move those devices towards the beginning of dpm_list, without breaking their ordering with respect to their parents and children. As a result, their resume routines are started much earlier and we are able to save much more device resume time this way. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

2010-02-26PM: Asynchronous suspend and resume of devicesRafael J. Wysocki4-6/+125
Theoretically, the total time of system sleep transitions (suspend to RAM, hibernation) can be reduced by running suspend and resume callbacks of device drivers in parallel with each other. However, there are dependencies between devices such that we're not allowed to suspend the parent of a device before suspending the device itself. Analogously, we're not allowed to resume a device before resuming its parent. The most straightforward way to take these dependencies into accout is to start the async threads used for suspending and resuming devices at the core level, so that async_schedule() is called for each suspend and resume callback supposed to be executed asynchronously. For this purpose, introduce a new device flag, power.async_suspend, used to mark the devices whose suspend and resume callbacks are to be executed asynchronously (ie. in parallel with the main suspend/resume thread and possibly in parallel with each other) and helper function device_enable_async_suspend() allowing one to set power.async_suspend for given device (power.async_suspend is unset by default for all devices). For each device with the power.async_suspend flag set the PM core will use async_schedule() to execute its suspend and resume callbacks. The async threads started for different devices as a result of calling async_schedule() are synchronized with each other and with the main suspend/resume thread with the help of completions, in the following way: (1) There is a completion, power.completion, for each device object. (2) Each device's completion is reset before calling async_schedule() for the device or, in the case of devices with the power.async_suspend flags unset, before executing the device's suspend and resume callbacks. (3) During suspend, right before running the bus type, device type and device class suspend callbacks for the device, the PM core waits for the completions of all the device's children to be completed. (4) During resume, right before running the bus type, device type and device class resume callbacks for the device, the PM core waits for the completion of the device's parent to be completed. (5) The PM core completes power.completion for each device right after the bus type, device type and device class suspend (or resume) callbacks executed for the device have returned.

The bast mode that appears in the debugfs output should be useful on both master and process nodes. lkb_highbast is currently printed, and is only useful on the master node. lkb_bastmode is only useful on the process node. This patch sets lkb_bastmode on the master node as well, and uses that value in the debugfs print. Signed-off-by: David Teigland <teigland@redhat.com>

2010-02-26V4L/DVB: gspca_main: some input error handling fixesHans de Goede1-9/+10
2 small changes to input device error handling: 1) Make it fatal when we fail to create an input device (it is either this or add checks for gspca_dev->input_dev being NULL in a lot of places) 2) Since we allow gspca_input_create_urb() to fail everywhere we call it, and thus never check its return value, make it void.
