We send direct probe to broadcast address, as some APs do not respond to unicast PROBE frames when unassociated. Broadcast frames are not acked, so we can not use that for trigger MLME state machine, but we need to use old timeout mechanism. This fixes authentication timed out like below: [ 1024.671974] wlan6: authenticate with 54:e6:fc:98:63:fe [ 1024.694125] wlan6: direct probe to 54:e6:fc:98:63:fe (try 1/3) [ 1024.695450] wlan6: direct probe to 54:e6:fc:98:63:fe (try 2/3) [ 1024.700586] wlan6: send auth to 54:e6:fc:98:63:fe (try 3/3) [ 1024.701441] wlan6: authentication with 54:e6:fc:98:63:fe timed out With fix, we have: [ 4524.198978] wlan6: authenticate with 54:e6:fc:98:63:fe [ 4524.220692] wlan6: direct probe to 54:e6:fc:98:63:fe (try 1/3) [ 4524.421784] wlan6: send auth to 54:e6:fc:98:63:fe (try 2/3) [ 4524.423272] wlan6: authenticated [ 4524.423811] wlan6: associate with 54:e6:fc:98:63:fe (try 1/3) [ 4524.427492] wlan6: RX AssocResp from 54:e6:fc:98:63:fe (capab=0x431 status=0 aid=1) Signed-off-by: Stanislaw Gruszka <sgruszka@xxxxxxxxxx> Signed-off-by: Johannes Berg <johannes.berg@xxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- net/mac80211/mlme.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) --- a/net/mac80211/mlme.c +++ b/net/mac80211/mlme.c @@ -3182,10 +3182,6 @@ static int ieee80211_probe_auth(struct i if (WARN_ON_ONCE(!auth_data)) return -EINVAL; - if (local->hw.flags & IEEE80211_HW_REPORTS_TX_ACK_STATUS) - tx_flags = IEEE80211_TX_CTL_REQ_TX_STATUS | - IEEE80211_TX_INTFL_MLME_CONN_TX; - auth_data->tries++; if (auth_data->tries > IEEE80211_AUTH_MAX_TRIES) { @@ -3219,6 +3215,10 @@ static int ieee80211_probe_auth(struct i auth_data->expected_transaction = trans; } + if (local->hw.flags & IEEE80211_HW_REPORTS_TX_ACK_STATUS) + tx_flags = IEEE80211_TX_CTL_REQ_TX_STATUS | + IEEE80211_TX_INTFL_MLME_CONN_TX; + ieee80211_send_auth(sdata, trans, auth_data->algorithm, status, auth_data->data, auth_data->data_len, auth_data->bss->bssid, @@ -3242,12 +3242,12 @@ static int ieee80211_probe_auth(struct i * will not answer to direct packet in unassociated state. */ ieee80211_send_probe_req(sdata, NULL, ssidie + 2, ssidie[1], - NULL, 0, (u32) -1, true, tx_flags, + NULL, 0, (u32) -1, true, 0, auth_data->bss->channel, false); rcu_read_unlock(); } - if (!(local->hw.flags & IEEE80211_HW_REPORTS_TX_ACK_STATUS)) { + if (tx_flags == 0) { auth_data->timeout = jiffies + IEEE80211_AUTH_TIMEOUT; ifmgd->auth_data->timeout_started = true; run_again(ifmgd, auth_data->timeout); Patches currently in stable-queue which might be from sgruszka@xxxxxxxxxx are queue-3.9/mac80211-use-just-spin_lock-in-ieee80211_get_tkip_p2k.patch queue-3.9/mac80211-fix-direct-probe-auth.patch -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
