Re: FAILED: patch "[PATCH] wifi: mac80211: capture fast-RX rate before mesh reuses" failed to apply to 6.18-stable tree

[Zhao Li <enderaoelyther@gmail.com>]

Hi Greg,

Please drop this for 6.18.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 6.18.y.

In 6.18.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 6.18.y, so d71c841be5d9 is not applicable to 6.18.y.

Thanks,
Zhao
