Hello Felix Fietkau, The patch 6d7b97b23e11: "ath5k: fix tx status reporting issues" from Apr 9, 2011, leads to the following static checker warning: "drivers/net/wireless/ath/ath5k/base.c:1683 ath5k_tx_frame_completed() error: buffer overflow 'info->status.rates' 4 <= 4" drivers/net/wireless/ath/ath5k/base.c 1675 for (i = 0; i < ts->ts_final_idx; i++) { 1676 struct ieee80211_tx_rate *r = 1677 &info->status.rates[i]; 1678 1679 r->count = tries[i]; 1680 } 1681 1682 info->status.rates[ts->ts_final_idx].count = ts->ts_final_retry; 1683 info->status.rates[ts->ts_final_idx + 1].idx = -1; ^^^^^^^^^^^^^^^^^^^^ It's complaining about this. 1684 ->ts_final_idx is set in ath5k_hw_proc_4word_tx_status() it comes from the hardware but in theory it could be a number between 0-3... I'm not sure. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
