Subject: [PATCH 0/3] allow DRM drivers to limit creation of blobs
Date: Thu,  7 Nov 2019 14:39:11 -0500
Message-ID: <1573155554-16248-1-git-send-email-cohens@codeaurora.org> (raw)

Fuzzers used in Android compliance testing repeatedly call the
create blob IOCTL which eventually exhausts the system memory.
This series adds a hook which allows drivers to impose their own
limitations on the size and/or number of blobs created.

Steve Cohen (3):
  drm: add driver hook for create blob limitations
  drm/msm: add support for createblob_check driver hook
  drm/msm/dpu: check blob limitations during create blob ioctl
