| * BKL: introduce CONFIG_BKL.Arnd Bergmann2010-10-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| * dvb-core: kill the big kernel lockArnd Bergmann2010-10-194-40/+11
| | | | | | | | | | | | | | | | | | | | | | | | The dvb core only uses the big kernel lock in the open and ioctl functions, which means it can be replaced with a dvb specific mutex. Fortunately, all the ioctl functions go through dvb_usercopy, so we can move the serialization in there.

* | v4l1: fix 32-bit compat microcode loading translationLinus Torvalds2010-10-151-11/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The compat code for the VIDIOCSMICROCODE ioctl is totally buggered. It's only used by the VIDEO_STRADIS driver, and that one is scheduled to staging and eventually removed unless somebody steps up to maintain it (at which point it should use request_firmware() rather than some magic ioctl). So we'll get rid of it eventually. But in the meantime, the compatibility ioctl code is broken, and this tries to get it to at least limp along (even if Mauro suggested just deleting it entirely, which may be the right thing to do - I don't think the compatibility translation code has ever worked unless you were very lucky).

| | | | | | | | | | | | | | | | | | | | | | | | When a driver that uses videobuf-dma-contig is used with the USERPTR memory access method a kernel oops might happen: a NULL address may be passed to dma_free_coherent().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | For some cards, ir_dev->props and ir_dev->raw are both NULL. These cards are using built-in IR decoding instead of raw, and can't easily be made to switch protocols. So upon reading /sys/class/rc/rc?/protocols on such a card, return 'builtin' as the supported and enabled protocol. Return -EINVAL on any attempts to change the protocol.

* | V4L/DVB: videobuf-dma-sg: set correct size in last sg elementHans Verkuil2010-09-271-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a nasty memory corruption bug when using userptr I/O. The function videobuf_pages_to_sg() sets up the scatter-gather list for the DMA transfer to the userspace pages. The first transfer is setup correctly (the size is set to PAGE_SIZE - offset), but all other transfers have size PAGE_SIZE. This is wrong for the last transfer which may be less than PAGE_SIZE. Most, if not all, drivers will program the boards DMA engine correctly, i.e. even though the size in the last sg element is wrong, they will do their own size calculations and make sure the right amount is DMA-ed, and so seemingly prevent memory corruption. However, behind the scenes the dynamic DMA mapping support (in lib/swiotlb.c) may create bounce buffers if the memory pages are not in DMA-able memory. This happens for example on a 64-bit linux with a board that only supports 32-bit DMA. These bounce buffers DO use the information in the sg list to determine the size. So while the DMA engine transfers the correct amount of data, when the data is 'bounced' back too much is copied, causing buffer overwrites. The fix is simple: calculate and set the correct size for the last sg list element.
