2008-10-03leds-pca955x: add proper error handling and fix bogus memory handlingSven Wegener
Check the return value of led_classdev_register and unregister all registered devices, if registering one device fails. Also the dynamic memory handling is totally bogus. You can't allocate multiple chunks via kzalloc() and expect them to be in order later. I wonder how this ever worked.

2008-10-03leds-fsg: change order of initialization and deinitializationSven Wegener
On initialization, we first do the ioremap and then register the led devices. On deinitialization, we do it in reverse order. This prevents someone calling into the brightness_set functions with an invalid latch_address.

When userspace uses SIGIO notification and forgets to disable it before closing file descriptor, rtc->async_queue contains stale pointer to struct file. When user space enables again SIGIO notification in different process, kernel dereferences this (poisoned) pointer and crashes. So disable SIGIO notification on close.

2008-10-03e1000e: Fix incorrect debug warningLinus Torvalds
Doing 'WARN_ON(preempt_count())' was horribly horribly wrong, and would cause tons of warnings at bootup if PREEMPT was enabled because the initcalls currently run with the kernel lock, which increments the preempt count. At the same time, the warning was also insufficient, since it didn't check that interrupts were enabled. The proper debug function to use for something that can sleep and wants a warning if it's called in the wrong context is 'might_sleep()'.

2008-10-02Check mapped ranges on sysfs resource filesLinus Torvalds
This is loosely based on a patch by Jesse Barnes to check the user-space PCI mappings though the sysfs interfaces. Quoting Jesse's original explanation: It's fairly common for applications to map PCI resources through sysfs. However, with the current implementation, it's possible for an application to map far more than the range corresponding to the resourceN file it opened. This patch plugs that hole by checking the range at mmap time, similar to what is done on platforms like sparc64 in their lower level PCI remapping routines. It was initially put together to help debug the e1000e NVRAM corruption problem, since we initially thought an X driver might be walking past the end of one of its mappings and clobbering the NVRAM. It now looks like that's not the case, but doing the check is still important for obvious reasons. and this version of the patch differs in that it uses a helper function to clarify the code, and does all the checks in pages (instead of bytes) in order to avoid overflows when doing "<< PAGE_SHIFT" etc. Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-10-01dm mpath: add missing path switching lockingChandra Seetharaman
Moving the path activation to workqueue along with scsi_dh patches introduced a race. It is due to the fact that the current_pgpath (in the multipath data structure) can be modified if changes happen in any of the paths leading to the lun. If the changes lead to current_pgpath being set to NULL, then it leads to the invalid access which results in the panic below. This patch fixes that by storing the pgpath to activate in the multipath data structure and properly protecting it. Note that if activate_path is called twice in succession with different pgpath, with the second one being called before the first one is done, then activate path will be called twice for the second pgpath, which is fine.

2008-09-30rt2x00: Fix build errors due to modularized rfkill or leds and built-in rt2x00.Gertjan van Wingerde
Fix by disabling rt2x00 rfkill support when rt2x00 is built-in and rfkill has been modularized, and a similar scheme for the relationship between leds_class and rt2x00.. Also, give a warning to the end-user when rfkill-/leds-support is disabled this way, so that the end-user has at least some clues on what is going on. Proper fixing required some general updates of the Kconfig-structure for the rt2x00 driver, whereby internal configuration symbols had to be moved to after the user-visible configuration symbols.
