From 413dafc8170fcb925fb17af8842f06af305f8e0b Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 21 Feb 2024 15:05:35 +0100 Subject: wifi: mac80211: only call drv_sta_rc_update for uploaded stations When a station has not been uploaded yet, receiving SMPS or channel width notification action frames can lead to rate_control_rate_update calling drv_sta_rc_update with uninitialized driver private data. Fix this by adding a missing check for sta->uploaded.
