Description Nick Reilly 2023-01-20 19:29:17 UTC 
sbin/ifconfig/ifieee80211.c in printmimo()
	for (i = 0; i < IEEE80211_MAX_CHAINS; i++) {
		if (mi->ch[i].rssi != 0) {
			r = 1;

But rssi is an array so the if statement is always true. Suggested fix is:
	for (i = 0; i < IEEE80211_MAX_CHAINS; i++) {
		if (mi->ch[i].rssi[0] != 0) {
			r = 1;


There are similar issues in sbin/pfctl/pfctl.c in pfctl_show_rules(). There are two instances (lines 1312 and 1366) of:

			if (rule.label[0] && (opts & PF_OPT_SHOWALL))
				labels = 1;

But rule is a two dimensional array so the if statement is always true. Suggested fix is:
			if (rule.label[0][0] && (opts & PF_OPT_SHOWALL))
				labels = 1;
