This -resulted in TX STBC being used for STAs not supporting RX STBC, which in -turn resulted in the STA not receiving anything. - -Fix this by handling the STBC flags in the same way mac80211 does. Mask -out RX STBC if we don't support TX STBC and vice versa. - -Tested only with the nl80211 driver and a STBC incapable STA. - -Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> ---- - -diff --git a/src/ap/ieee802_11_ht.c b/src/ap/ieee802_11_ht.c -index 1b39a6a..b193ee0 100644 ---- a/src/ap/ieee802_11_ht.c -+++ b/src/ap/ieee802_11_ht.c -@@ -256,7 +256,15 @@ void hostapd_get_ht_capab(struct hostapd_data *hapd, - cap &= hapd->iconf->ht_capab; - cap |= (hapd->iconf->ht_capab & HT_CAP_INFO_SMPS_DISABLED); - -- /* FIXME: Rx STBC needs to be handled specially */ -- cap |= (hapd->iconf->ht_capab & HT_CAP_INFO_RX_STBC_MASK); -+ /* -+ * STBC needs to be handled specially -+ * if we don't support RX STBC, mask out TX STBC in the STA's HT caps -+ * if we don't support TX STBC, mask out RX STBC in the STA's HT caps -+ */ -+ if (!(hapd->iconf->ht_capab & HT_CAP_INFO_RX_STBC_MASK)) -+ cap &= ~HT_CAP_INFO_TX_STBC; -+ if (!(hapd->iconf->ht_capab & HT_CAP_INFO_TX_STBC)) -+ cap &= ~HT_CAP_INFO_RX_STBC_MASK; -+ - neg_ht_cap->ht_capabilities_info = host_to_le16(cap); - } |
