[PATCH v3 0/2] drm/nouveau/dmem: Fix Vulnerability and Device Channels configuration
From: Yonatan Maman <Ymaman at Nvidia.com>
This patch series addresses two critical issues in the Nouveau driver
related to device channels, error handling, and sensitive data leaks.
- Vulnerability in migrate_to_ram: The migrate_to_ram function might
return a dirty HIGH_USER page when a copy push command (FW channel)
fails, potentially exposing sensitive data and posing a security

[PATCH 2/2] nouveau/dmem: Fix memory leak in `migrate_to_ram` upon copy error
...rn a
dirty HIGH_USER page to the user.
This exposes a security vulnerability in the nouveau driver. To prevent
memory leaks in `migrate_to_ram` upon a copy error, allocate a zero
page for the destination page.

[PATCH v1 0/4] GPU Direct RDMA (P2P DMA) for Device Private Pages
From: Yonatan Maman <Ymaman at Nvidia.com>
This patch series aims to enable Peer-to-Peer (P2P) DMA access in
GPU-centric applications that utilize RDMA and private device pages. This
enhancement is crucial for minimizing data transfer overhead by allowing
the GPU to directly expose device private page data to devices such as
NICs, eliminating the need to traverse system RAM, which is the
