Subject: [PATCH ath-next 0/6] wifi: ath12k: fix monitor RX buffer lifecycle issues
Date: Wed, 16 Sep 2026 14:03:19 +0800 [thread overview]
Message-ID: <20260916060325.854-1-kang.yang@oss.qualcomm.com> (raw)
This series fixes several monitor RX buffer management bugs in the
monitor destination path.
The fixes address leaked skb buffers, stale monitor descriptor state,
object lifetime issues, and incorrect DMA unmap handling observed in
various error and corner cases.
Kang Yang (6):
wifi: ath12k: fix skb leak on paddr mismatch in wifi7 mon RX pop
wifi: ath12k: free pending MSDUs on duplicate mon link descriptor
wifi: ath12k: fix stale tail_msdu pointer returned from mpdu_pop
wifi: ath12k: place dp_mon_mpdu on stack in mon dst reap loop
wifi: ath12k: fix skb leak on monitor PPDU ID wraparound
wifi: ath12k: avoid double DMA unmap of held monitor RX buffers
