Subject: [PATCH iwl-net v2 0/2] e1000e: fix Rx DMA error handling
Date: Sun, 13 Sep 2026 13:15:53 -0400	[thread overview]
Message-ID: <20260913171555.89537-1-tactii@gmail.com> (raw)

Fix some longstanding bugs in Rx DMA error handling.

These two patches eliminate some conditions which would result in
DMA_MAPPING_ERROR being sent to h/w or to dma_unmap_page() or
dma_unmap_single(). A teardown leak in the packet-splitting path is also
fixed by a necessary refactor.

v2:
* Renamed series from "e1000e: fix Rx bugs"
* Removed RXALL buffer overrun fix from the series.
  RXALL bugs will be fixed in a separate series.
* Reworded patch commit messages.

Matt Vollrath (2):
  e1000e: fix Rx skb DMA map error sentinel
  e1000e: fix ps_pages DMA map error sentinel
