I hit this warn-on, not to sure exactly why.
This was on an ath9k system with .37-rc2 wireless testing from yesterday.
29 STA interfaces.
static void __cfg80211_auth_remove(struct wireless_dev *wdev, const u8 *addr)
{
int i;
bool done = false;
ASSERT_WDEV_LOCK(wdev);
for (i = 0; addr && i < MAX_AUTH_BSSES; i++) {
if (wdev->authtry_bsses[i] &&
memcmp(wdev->authtry_bsses[i]->pub.bssid,
addr, ETH_ALEN) == 0) {
cfg80211_unhold_bss(wdev->authtry_bsses[i]);
cfg80211_put_bss(&wdev->authtry_bsses[i]->pub);
wdev->authtry_bsses[i] = NULL;
done = true;
break;
}
}
WARN_ON(!done);
}
