android: unconditionally remove callbacks in sync_fence_free()

2015-12-21T21:37:53Z

Using fence->status to determine whether or not there are callbacks remaining on the sync_fence is racy since fence->status may have been decremented to 0 on another CPU before fence_check_cb_func() has completed. By unconditionally calling fence_remove_callback() for each fence in the sync_fence, we guarantee that each callback has either completed (since fence_remove_callback() grabs the fence lock) or been removed.

staging: android: sync: Fix memory corruption in sync_timeline_signal().

2015-03-26T09:58:51Z

The android_fence_release() function checks for active sync points by calling list_empty() on the list head embedded on the sync point. However, it is only valid to use list_empty() on nodes that have been initialized with INIT_LIST_HEAD() or list_del_init(). Because the list entry has likely been removed from the active list by sync_timeline_signal(), there is a good chance that this WARN_ON_ONCE() will be hit due to dangling pointers pointing at freed memory (even though the sync drivers did nothing wrong) and memory corruption will ensue as the list entry is removed for a second time, corrupting the active list. This problem can be reproduced quite easily with CONFIG_DEBUG_LIST=y and fences with more than one sync point.

Pull staging driver updates from Greg KH: "Here's the big pull request for the staging driver tree for 3.17-rc1. Lots of things in here, over 2000 patches, but the best part is this: 1480 files changed, 39070 insertions(+), 254659 deletions(-) Thanks to the great work of Kristina Martšenko, 14 different staging drivers have been removed from the tree as they were obsolete and no one was willing to work on cleaning them up. Other than the driver removals, loads of cleanups are in here (comedi, lustre, etc.) as well as the usual IIO driver updates and additions.
