2011-12-22staging:iio: Disallow modifying buffer size when buffer is enabledLars-Peter Clausen
The buffer buffer storage is only update when enabling the buffer. Changing the buffer size while the buffer is enabled will confuse the buffer in regard to its actual buffer size and can cause potential memory corruption. Thus it is only safe to modify the buffer size when the buffer is disabled.

2011-12-22staging:iio: Disallow changing scan elements in all buffered modesLars-Peter Clausen
Currently we only disallow changing the scan elements, while the buffer is enabled, in triggered buffer mode. This patch changes it to disallow it for all buffered modes. Disabling or enabling scan elements while the buffer is enabled will cause undefined behavior since the reader will not be able to tell samples with the new and old scan element set apart and thus wont be able to extract any meaningful data from the buffer.

2011-12-22Staging: bcm: Fix an invalid dereference to a kmalloc in IOCTL_BCM_BULK_WRMKevin McKinney
Variable IoBuffer.InputLength is chosen from userspace, and can therefore be less than the intended size. In this case,the memory from the kmalloc call is eventually cast to a PBULKWRM_BUFFER. If the IoBuffer.InputLength does not meet the minimum size of PBULKWRM_BUFFER, then we will get a kernel Oops. To resolve this issue, this patch verifies IoBuffer.InputLength meets the minimum size before invoking the kmalloc call.

2011-12-22Staging: bcm: Fix information leak in IOCTL_BCM_GET_DRIVER_VERSIONKevin McKinney
This ioctl, IOCTL_BCM_GET_DRIVER_VERSION, is responsible for sending the driver version to userspace. However, the requested size stored in IoBuffer.OutputLength may be incorrect. Therefore, we altered the code to send the exact length of the version, plus one for the null character.

2011-12-21ashmem: Anonymous shared memory subsystemRobert Love
The anonymous shared memory (ashmem) subsystem provides a Unix-y,file-based shared memory interface to user-space. It works like anonymous memory (e.g. mmapping fd=0) except if you share the file descriptor via the usual means, you will share the mapping. The shared memory can be accessed via both mmap or file I/O. The backing store is a simple shmem file. Additionally, ashmem introduces the concept of page pinning. Pinned pages (the default) behave like any anonymous memory. Unpinned pages are available to the kernel for eviction during VM pressure. When repinning the pages, the return value instructs user-space as to any eviction. In this manner, user-space processes may implement caching and similar resource management that efficiently integrates with kernel memory management. Signed-off-by: Robert Love <rlove@google.com> ashmem: Don't install fault handler for private mmaps. Ashmem is used to create named private heaps. If this heap is backed by a tmpfs file it will allocate two pages for every page touched. In 2.6.27, the extra page would later be freed, but 2.6.29 does not scan anonymous pages when running without swap so the memory is not freed while the file is referenced. This change changes the behavior of private ashmem mmaps to match /dev/zero instead tmpfs.
