2014-08-21[media] vb2: use pr_info instead of pr_debugHans Verkuil
Modern kernels enable dynamic printk support, which is fine, except when it is combined with a debug module option. Enabling debug in videobuf2-core now produces no debugging unless it is also enabled through the dynamic printk support in debugfs. Either use a debug module option + pr_info, or use pr_debug without a debug module option. In this case the fact that you can set various debug levels is very useful, so I believe that for videobuf2-core.c we should use pr_info. The mix of the two is very confusing: I've spent too much time already trying to figure out why I am not seeing any debug output in the kernel log when I do: echo 1 >/sys/modules/videobuf2_core/parameters/debug Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

But elsewhere in the code the core lock is taken first but calls to copy_to/from_user() can take the mmap_sem semaphore as well, potentially causing a classical A-B/B-A deadlock. However, the mmap/get_unmapped_area calls really shouldn't take the core lock at all. So what would happen if they don't take the core lock anymore? There are two situations that need to be taken into account: calling mmap while new buffers are being added and calling mmap while buffers are being deleted. The first case works almost fine without a lock: in all cases mmap relies on correctly filled-in q->num_buffers/q->num_planes values and those are only updated by reqbufs and create_buffers *after* any new buffers have been initialized completely. Except in one case: if an error occurred while allocating the buffers it will increase num_buffers and rely on __vb2_queue_free to decrease it again. So there is a short period where the buffer information may be wrong. The second case definitely does pose a problem: buffers may be in the process of being deleted, without the internal structure being updated. In order to fix this a new mutex is added to vb2_queue that is taken when buffers are allocated or deleted, and in vb2_mmap. That way vb2_mmap won't get stale buffer data. Note that this is a problem only for MEMORY_MMAP, so even though __qbuf_userptr and __qbuf_dmabuf also mess around with buffers (mem_priv in particular), this doesn't clash with vb2_mmap or vb2_get_unmapped_area since those are MMAP specific. As an additional bonus the hack in __buf_prepare, the USERPTR case, can be removed as well since mmap() no longer takes the core lock. All in all a much cleaner solution.
