Subject: [PATCH v2 0/3] Videobuf2 corner case fixes
Date: Tue,  8 Jan 2019 10:58:33 +0200	[thread overview]
Message-ID: <20190108085836.9376-1-sakari.ailus@linux.intel.com> (raw)

Hi all,

Here's a second version of the set fixing a few videobuf2 corner cases.
Most drivers have limits for the size already but not necessarily all of
them.

since v1:

- Add a sanity check for alignment in vb2_dma_sg_alloc_compacted.

- Add a comment in __vb2_buf_mem_alloc noting that the size shall be page
  aligned.

Sakari Ailus (3):
  videobuf2-core: Prevent size alignment wrapping buffer size to 0
  videobuf2-dma-sg: Prevent size from overflowing
  videobuf2-core.h: Document the alloc memop size argument as page
    aligned

 drivers/media/common/videobuf2/videobuf2-core.c   | 5 +++++
 drivers/media/common/videobuf2/videobuf2-dma-sg.c | 5 ++++-
 include/media/videobuf2-core.h                    | 3 ++-
