Subject: [PATCH 0/3] Videobuf2 corner case fixes
Date: Thu, 13 Dec 2018 12:40:03 +0200	[thread overview]
Message-ID: <20181213104006.401-1-sakari.ailus@linux.intel.com> (raw)

Hi folks,

Most drivers already have limits to size such that you don't hit these,
but if you do, then mayhem will follow. The two first are cc'd to stable.

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   | 4 ++++
 drivers/media/common/videobuf2/videobuf2-dma-sg.c | 2 +-
