Hi Greg,
Please drop this for 6.6.y; no backport is needed there.
The failing cherry-pick is expected because the code fixed by
d71c841be5d9 ("wifi: mac80211: capture fast-RX rate before mesh reuses
skb->cb") is not present in 6.6.y.
In 6.6.y, the fast-RX mesh RX_QUEUED arm is:
res = ieee80211_rx_mesh_data(rx->sdata, rx->sta, rx->skb);
switch (res) {
case RX_QUEUED:
return true;
The later vulnerable post-mesh stats update:
stats->last_rx = jiffies;
stats->last_rate = sta_stats_encode_rate(status);
was introduced by:
cc18fffa3a517 ("wifi: mac80211: fix missing RX bitrate update for mesh forwarding path")
That code is not in 6.6.y, so d71c841be5d9 is not applicable to 6.6.y.
Thanks,
Zhao
