| * define platform wakeup hook, use in pci_enable_wake()David Brownell2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This defines a platform hook to enable/disable a device as a wakeup event source. It's initially for use with ACPI, but more generally it could be used whenever enable_irq_wake()/disable_irq_wake() don't suffice. The hook is called -- if available -- inside pci_enable_wake(); and the semantics of that call are enhanced so that support for PCI PME# is no longer needed. It can now work for devices with "legacy PCI PM", when platform support allows it. (That support would use some board-specific signal for for the same purpose as PME#.)

| * security: prevent permission checking of file removal via sysfs_remove_group()James Morris2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent permission checking from being performed when the kernel wants to unconditionally remove a sysfs group, by introducing an kernel-only variant of lookup_one_len(), lookup_one_len_kern(). Additionally, as sysfs_remove_group() does not check the return value of the lookup before using it, a BUG_ON has been added to pinpoint the cause of any problems potentially caused by this (and as a form of annotation).

| * s390: cio: Delay uevents for subchannelsCornelia Huck2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We often have the situation that we register a subchannel and start device recognition, only to find out that the device is not usable after all, which triggers an unregister of the subchannel. This often happens on hundreds of subchannels on a LPAR, leading to a storm of events which aren't of any use. Therefore, use uevent_suppress to delay the KOBJ_ADD uevent for a subchannel until we know that its ccw_device is to be registered.

It is not needed at all and can be removed. Note, we now have an empty release function for the driver structure. This is due to the fact that drivers are statically allocated in the system at this point in time, something which I want to change in the future. But remember, drivers are really code, which is reference counted by the module, unlike devices, which are data and _must_ be reference counted properly in order to work correctly.

The command "drivers_probe" accepts a bus_id and the bus tries to bind a driver to this device. Systems who want to control the driver binding with udev, switch off the bus initiated probing: echo 0 > /sys/subsystem/usb/drivers_autoprobe echo 0 > /sys/subsystem/pcmcia/drivers_autoprobe ... and initiate the probing with udev rules like: ACTION=="add", SUBSYSTEM=="usb", ATTR{subsystem/drivers_probe}="$kernel" ACTION=="add", SUBSYSTEM=="pcmcia", ATTR{subsystem/drivers_probe}="$kernel" ... Custom driver binding can happen in earlier rules by something like: ACTION=="add", SUBSYSTEM=="usb", \ ATTRS{idVendor}=="1234", ATTRS{idProduct}=="5678" \ ATTR{subsystem/drivers/<custom-driver>/bind}="$kernel" This is intended to solve the modprobe.conf mess with "install-rules", custom bind/unbind-scripts and all the weird things people invented over the years. It should also provide the functionality "libusual" was supposed to do. With udev, one can just write a udev rule to drive all USB-disks at the third port of USB-hub by the "ub" driver, and everything else by usb-storage. One can also instruct udev to bind different wireless drivers to identical cards - just selected by the pcmcia slot-number, and whatever ... To use the mentioned rules, it needs udev version 106, to be able to write ATTR{}="$kernel" to sysfs files. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * dev_printk and new-style class devicesJean Delvare2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the new-style class devices (as opposed to old-style struct class_device) are becoming more widely used, I noticed that the dev_printk-based functions are not working properly with these. New-style class devices have no driver nor bus, almost by definition, and as a result dev_driver_string(), which is used as the first parameter of dev_printk, resolves to an empty string. This causes entries like the following to show in my logs: i2c-2: adapter [SMBus stub driver] registered Notice the unaesthetical leading whitespace. In order to fix this problem, I suggest that we extend dev_driver_string to deal with new-style class devices: Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * driver core: fix namespace issue with devices assigned to classesKay Sievers2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - uses a kset in "struct class" to keep track of all directories belonging to this class - merges with the /sys/devices/virtual logic. - removes the namespace-dir if the last member of that class leaves the directory. There may be locking or refcounting fixes left, I stopped when it seemed to work with network and sound modules. :) From: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * | selinux: preserve boolean values across policy reloadsStephen Smalley2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, the userland policy loading code has to go through contortions to preserve boolean values across policy reloads, and cannot do so atomically. As this is what we always want to do for reloads, let the kernel preserve them instead.
