* [SCSI] Re-do "final klist fixes"Linus Torvalds2005-09-07

* [PATCH] fix klist semantics for lists which have elements removed on traversalJames Bottomley2005-09-07
| | | | | | | | | | | | | | | | | | | | | The problem is that klists claim to provide semantics for safe traversal of lists which are being modified. The failure case is when traversal of a list causes element removal (a fairly common case). The issue is that although the list node is refcounted, if it is embedded in an object (which is universally the case), then the object will be freed regardless of the klist refcount leading to slab corruption because the klist iterator refers to the prior element to get the next. The solution is to make the klist take and release references to the embedding object meaning that the embedding object won't be released until the list relinquishes the reference to it.

| | * [SCSI] attribute container final klist fixesJames Bottomley2005-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the attribute container deletes from a klist while it's walking it, it is vulnerable to the problem (and fix) here: http://marc.theaimsgroup.com/?l=linux-scsi&m=112485448830217 The attached fixes this (but won't compile without the above). It also fixes the logical reversal in the traversal loop which meant that we were never actually traversing the loop to hit this bug in the first place.

| | * [SCSI] correct attribute_container list usageJames Bottomley2005-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the changes in the attribute_container code in the scsi-misc tree was to add a lock to protect the list of devices per container. This, unfortunately, leads to potential scheduling while atomic problems if there's a sleep in the function called by a trigger. The correct solution is to use the kernel klist infrastructure instead which allows lockless traversal of a list. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I recently tried to construct a totally generic transport class and found there were certain features missing from the current abstract transport class. Most notable is that you have to hang the data on the class_device but most of the API is framed in terms of the generic device, not the class_device. These changes are two fold - Provide the class_device to all of the setup and configure APIs - Provide and extra API to take the device and the attribute class and return the corresponding class_device Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* | [PATCH] driver core: Add the ability to bind drivers to devices from userspaceGreg Kroah-Hartman2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a single file, "bind", to the sysfs directory of every driver registered with the driver core. To bind a device to a driver, write the bus id of the device you wish to bind to that specific driver to the "bind" file (remember to not add a trailing \n). If that bus id matches a device on that bus, and it does not currently have a driver bound to it, the probe sequence will be initiated with that driver and device. Note, this requires that the driver itself be willing and able to accept that device (usually through a device id type table). This patch does not make it possible to override the driver's id table.

Each zone has a per-cpu array of pagesets. So any particular CPU has some memory in each zone structure which belongs to itself. Even if that CPU is not local to that zone. So the patch relocates the pagesets for each cpu to the node that is nearest to the cpu instead of allocating the pagesets in the (possibly remote) target zone. This means that the operations to manage pages on remote zone can be done with information available locally. We play a macro trick so that non-NUMA pmachines avoid the additional pointer chase on the page allocator fastpath.

* | [PATCH] driver core: Fix races in driver_detach()Alan Stern2005-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is intended for your "driver" tree. It fixes several subtle races in driver_detach() and device_release_driver() in the driver-model core. The major change is to use klist_remove() rather than klist_del() when taking a device off its driver's list. There's no other way to guarantee that the list pointers will be updated before some other driver binds to the device. For this to work driver_detach() can't use a klist iterator, so the loop over the devices must be written out in full. In addition the patch protects against the possibility that, when a driver and a device are unregistered at the same time, one may be unloaded from memory before the other is finished using it.

* | [PATCH] Driver Core: fix bk-driver-core kills ppc64Patrick Mochel2005-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no check to see if the device is already bound to a driver, which could do bad things. The first thing to go wrong is that it will try to match a driver with a device already bound to one. In some cases (it appears with USB with drivers/usb/core/usb.c::usb_match_id()), some drivers will match a device based on the class type, so it would be common (especially for HID devices) to match a device that is already bound. The fun comes when ->probe() is called, it fails, then driver_probe_device() does this: dev->driver = NULL; Later on, that pointer could be be dereferenced without checking and cause hell to break loose. This problem could be nasty. It's very hardware dependent, since some devices could have a different set of matching qualifiers than others. Now, I don't quite see exactly where/how you were getting that crash. You're dereferencing bad memory, but I'm not sure which pointer was bad and where it came from, but it could have come from a couple of different places. The patch below will hopefully fix it all up for you. It's against 2.6.12-rc2-mm1, and does the following: - Move logic to driver_probe_device() and comments uncommon returns: 1 - If device is bound 0 - If device not bound, and no error error - If there was an error. - Move locking to caller of that function, since we want to lock a device for the entire time we're trying to bind it to a driver (to prevent against a driver being loaded at the same time). - Update __device_attach() and __driver_attach() to do that locking. - Check if device is already bound in __driver_attach() - Update the converse device_release_driver() so it locks the device around all of the operations. - Mark driver_probe_device() as static and remove export. It's an internal function, it should stay that way, and there are no other callers. If there is ever a need to export it, we can audit it as necessary. Signed-off-by: Andrew Morton <akpm@osdl.org>
