These callbacks are currently used by the individual buffer implementations to ensure that the request_update callback is not issued while the buffer is in use. But the core already provides sufficient measures to prevent this from happening in the first place. So it is safe to remove them. There is one functional change due to this patch. Since the buffer is no longer marked as in use when the chrdev is opened, it is now possible to enable the buffer while it is opened. This did not work before, because mark_param_change did fail if the buffer was marked as in use.

Right now we have a mark_param_change callback in the buffer access functions struct, which should be called whenever the parameters (length, bytes per datum) of the buffer change. But it is only called when the user changes the buffer size, not when the bytes per datum change. Additionally each buffer implementation already keeps track internally whether its parameters have changed, making the call to mark_param_change after changing the buffer length redundant. Since each buffer implementation knows best when one of its parameters has changed just make tracking of this internal and drop the mark_param_change callback.

Our buffer implementation does not support multiple concurrent readers. So we have to ensure that a device is only opened once at a time. So do the same thing we do for the event fd and introduce a per device busy flag. The flag gets set when opening the device and gets cleared when closing the device. If a open is attempted while the busy flag is set we return -EBUSY.

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.

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.

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.

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.

Robert Love authored
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.
