      "message": "Driver core: add notification of bus events\n\nI finally did as you suggested and added the notifier to the struct\nbus_type itself. There are still problems to be expected is something\nattaches to a bus type where the code can hook in different struct\ndevice sub-classes (which is imho a big bogosity but I won\u0027t even try to\nargue that case now) but it will solve nicely a number of issues I\u0027ve\nhad so far.\n\nThat also means that clients interested in registering for such\nnotifications have to do it before devices are added and after bus types\nare registered. Fortunately, most bus types that matter for the various\nusage scenarios I have in mind are registerd at postcore_initcall time,\nwhich means I have a really nice spot at arch_initcall time to add my\nnotifiers.\n\nThere are 4 notifications provided. Device being added (before hooked to\nthe bus) and removed (failure of previous case or after being unhooked\nfrom the bus), along with driver being bound to a device and about to be\nunbound.\n\nThe usage I have for these are:\n\n - The 2 first ones are used to maintain a struct device_ext that is\nhooked to struct device.firmware_data. This structure contains for now a\npointer to the Open Firmware node related to the device (if any), the\nNUMA node ID (for quick access to it) and the DMA operations pointers \u0026\niommu table instance for DMA to/from this device. For bus types I own\n(like IBM VIO or EBUS), I just maintain that structure directly from the\nbus code when creating the devices. But for bus types managed by generic\ncode like PCI or platform (actually, of_platform which is a variation of\nplatform linked to Open Firmware device-tree), I need this notifier.\n\n - The other two ones have a completely different usage scenario. I have\ncases where multiple devices and their drivers depend on each other. For\nexample, the IBM EMAC network driver needs to attach to a MAL DMA engine\nwhich is a separate device, and a PHY interface which is also a separate\ndevice. They are all of_platform_device\u0027s (well, about to be with my\nupcoming patches) but there is no say in what precise order the core\nwill \"probe\" them and instanciate the various modules. The solution I\nfound for that is to have the drivers for emac to use multithread_probe,\nand wait for a driver to be bound to the target MAL and PHY control\ndevices (the device-tree contains reference to the MAL and PHY interface\nnodes, which I can then match to of_platform_devices). Right now, I\u0027ve\nbeen polling, but with that notifier, I can more cleanly wait (with a\ntimeout of course).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

      "message": "Driver core: Fix potential deadlock in driver core\n\nThere is a potential deadlock in the driver core.  It boils down to\nthe fact that bus_remove_device() calls klist_remove() instead of\nklist_del(), thereby waiting until the reference count of the\nklist_node in the bus\u0027s klist of devices drops to 0.  The refcount\ncan\u0027t reach 0 so long as a modprobe process is trying to bind a new\ndriver to the device being removed, by calling __driver_attach().  The\nproblem is that __driver_attach() tries to acquire the device\u0027s\nparent\u0027s semaphore, but the caller of bus_remove_device() is quite\nlikely to own that semaphore already.\n\nIt isn\u0027t sufficient just to replace klist_remove() with klist_del().\nDoing so runs the risk that the device would remain on the bus\u0027s klist\nof devices for some time, and so could be bound to another driver even\nafter it was unregistered.  What\u0027s needed is a new way to distinguish\nwhether or not a device is registered, based on a criterion other than\nwhether its klist_node is linked into the bus\u0027s klist of devices.  That\nway driver binding can fail when the device is unregistered, even if\nit is still linked into the klist.\n\nThis patch (as782) implements the solution, by adding a new bitflag to\nindiate when a struct device is registered, by testing the flag before\nallowing a driver to bind a device, and by changing the definition of\nthe device_is_registered() inline.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

This facility is needed by USB device drivers,\nowing to the peculiar way USB devices work:\n\n\tA device provides multiple interfaces, and drivers are bound\n\tto interfaces rather than to devices;\n\n\tNevertheless a reset, reset-configuration, suspend, or resume\n\taffects the entire device and requires the caller to hold the\n\tlock for the device, not just a lock for one of the interfaces.\n\nSince a USB driver\u0027s probe method is always called with the interface\nlock held, the locking order rules (always lock parent before child)\nprevent these methods from acquiring the device lock.  The solution\nprovided here is to call all probe and remove methods, for all devices\n(not just USB), with the parent lock already acquired.\n\nAlthough currently only the USB subsystem requires these changes, people\nhave mentioned in prior discussion that the overhead of acquiring an\nextra semaphore in all the prove/remove sequences is not overly large.\n\nUp to now, the USB core has been using its own set of private\nsemaphores.  A followup patch will remove them, relying entirely on the\ndevice semaphores provided by the driver core.\n\nThe code paths affected by this patch are:\n\n\tdevice_add and device_del: The USB core already holds the parent\n\tlock, so no actual change is needed.\n\n\tdriver_register and driver_unregister: The driver core will now\n\tlock both the parent and the device before probing or removing.\n\n\tdriver_bind and driver_unbind (in sysfs): These routines will\n\tnow lock both the parent and the device before binding or\n\tunbinding.\n\n\tbus_rescan_devices: The helper routine will lock the parent\n\tbefore probing a device.\n\nI have not tested this patch for conflicts with other subsystems.  As\nfar as I can see, the only possibility of conflict would lie in the\nbus_rescan_devices pathway, and it seems pretty remote.  Nevertheless,\nit would be good for this to get a lot of testing in -mm.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n"

Another thread calls\nbus_rescan_devices().  Now when bus_rescan_devices_helper() checks for\ndev-\u003edriver it is still NULL \u0027cos the the prior device_attach() is not yet\nfinished.  But as soon as the first one releases the dev-\u003esem the second\ndevice_attach() tries to rebind the already bound device again.\ndevice_bind_driver() does this blindly which leads to a corrupt\ndriver-\u003eklist_devices list (the device links itself, the head points to the\ndevice).  Later a call to device_release_driver() sets dev-\u003edriver to NULL\nand breaks the link it has to itself on knode_driver.  Rmmoding the driver\nlater calls driver_detach() which leads to an endless loop \u0027cos the list\nhead in klist_devices still points to the device.  And since dev-\u003edriver is\nNULL it\u0027s stuck with the same device forever.  Boom.  And rmmod hangs.\n\nVery easy to reproduce with new-style pcmcia and a 16bit card.  Just loop\nmodprobe \u003cpcmcia-modules\u003e ;cardctl eject; rmmod \u003ccard driver, pcmcia\nmodules\u003e.\n\nEasiest fix is to check if the device is already bound to a driver in\ndevice_bind_driver().

      "message": "[PATCH] Driver Core: fix bk-driver-core kills ppc64\n\nThere\u0027s no check to see if the device is already bound to a driver, which\ncould do bad things.  The first thing to go wrong is that it will try to match\na driver with a device already bound to one.  In some cases (it appears with\nUSB with drivers/usb/core/usb.c::usb_match_id()), some drivers will match a\ndevice based on the class type, so it would be common (especially for HID\ndevices) to match a device that is already bound.\n\nThe fun comes when -\u003eprobe() is called, it fails, then\ndriver_probe_device() does this:\n\n\tdev-\u003edriver \u003d NULL;\n\nLater on, that pointer could be be dereferenced without checking and cause\nhell to break loose.\n\nThis problem could be nasty. It\u0027s very hardware dependent, since some\ndevices could have a different set of matching qualifiers than others.\n\nNow, I don\u0027t quite see exactly where/how you were getting that crash.\nYou\u0027re dereferencing bad memory, but I\u0027m not sure which pointer was bad\nand where it came from, but it could have come from a couple of different\nplaces.\n\nThe patch below will hopefully fix it all up for you. It\u0027s against\n2.6.12-rc2-mm1, and does the following:\n\n- Move logic to driver_probe_device() and comments uncommon returns:\n  1 - If device is bound\n  0 - If device not bound, and no error\n  error - If there was an error.\n\n- Move locking to caller of that function, since we want to lock a\n  device for the entire time we\u0027re trying to bind it to a driver (to\n  prevent against a driver being loaded at the same time).\n\n- Update __device_attach() and __driver_attach() to do that locking.\n\n- Check if device is already bound in __driver_attach()\n\n- Update the converse device_release_driver() so it locks the device\n  around all of the operations.\n\n- Mark driver_probe_device() as static and remove export. It\u0027s an\n  internal function, it should stay that way, and there are no other\n  callers. If there is ever a need to export it, we can audit it as\n  necessary.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\n"
