2011-06-08Bluetooth: Check advertising cache in hci_connect()Andre Guedes
When connecting to a LE device, we need to check the advertising cache in order to know the address type of that device. If its advertising entry is not found, the connection is not established and hci_connect() returns error.

2011-06-08Bluetooth: Remove useless check in hci_connect()Andre Guedes
There is no need to check the connection's state since hci_conn_add() has just created a new connection and its state has been set properly.

2011-06-08Bluetooth: Add 'dst_type' field to struct hci_connAndre Guedes
This patch adds a new field (dst_type) to the struct hci_conn which holds the type of the destination address (bdaddr_t dst). This approach is needed in order to use the struct hci_conn as an abstraction of LE connections in HCI Layer. For non-LE this field is ignored. This patch also set properly the 'dst_type' field after initializing LE hci_conn structures. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo F.

2011-06-08Bluetooth: Fix auth_complete_evt for legacy unitsWaldemar Rymarkiewicz
Legacy devices don't re-authenticate the link properly if a link key already exists. Thus, don't update sec_level for this case even if hci_auth_complete_evt indicates success. Otherwise the sec_level will not reflect a real security on the link. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-06-08Bluetooth: Advertising entries lifetimeAndre Guedes
This patch adds a timer to clear 'adv_entries' after three minutes. After some amount of time, the advertising entries cached during the last LE scan should be considered expired and they should be removed from the advertising cache. It was chosen a three minutes timeout as an initial attempt. This value might change in future. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo F.

2011-06-08Bluetooth: Remove export of l2cap_chan_clear_timer()Gustavo F. Padovan

2011-06-08mac80211: fix IBSS teardown raceJohannes Berg
Ignacy reports that sometimes after leaving an IBSS joining a new one didn't work because there still were stations on the list. He fixed it by flushing stations when attempting to join a new IBSS, but this shouldn't be happening in the first case. When I looked into it I saw a race condition in teardown that could cause stations to be added after flush, and thus cause this situation. Ignacy confirms that after applying my patch he hasn't seen this happen again.

2011-06-07mac80211: Stop BA session event from deviceShahar Levi
Some devices support BT/WLAN co-existence algorigthms. In order not to harm the system performance and user experience, the device requests not to allow any RX BA session and tear down existing RX BA sessions based on system constraints such as periodic BT activity that needs to limit WLAN activity (eg.SCO or A2DP). In such cases, the intention is to limit the duration of the RX PPDU and therefore prevent the peer device to use A-MPDU aggregation. Adding ieee80211_stop_rx_ba_session() callback that can be used by the driver to stop existing BA sessions. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: John W.

2011-06-07nl80211: fix overflow in ssid_lenLuciano Coelho
When one of the SSID's length passed in a scan or sched_scan request is larger than 255, there will be an overflow in the u8 that is used to store the length before checking. This causes the check to fail and we overrun the buffer when copying the SSID. Fix this by checking the nl80211 attribute length before copying it to the struct. This is a follow up for the previous commit 208c72f4fe44fe09577e7975ba0e7fa0278f3d03, which didn't fix the problem entirely.

2011-06-07net: cpu offline cause napi stallHeiko Carstens
Frank Blaschka reported : <quote> During heavy network load we turn off/on cpus. Sometimes this causes a stall on the network device. Digging into the dump I found out following: napi is scheduled but does not run. From the I/O buffers and the napi state I see napi/rx_softirq processing has stopped because the budget was reached. napi stays in the softnet_data poll_list and the rx_softirq was raised again. I assume at this time the cpu offline comes in, the rx softirq is raised/moved to another cpu but napi stays in the poll_list of the softnet_data of the now offline cpu. Reviewing dev_cpu_callback (net/core/dev.c) I did not find the poll_list is transfered to the new cpu. </quote> This patch is a straightforward implementation of Frank suggestion : Transfert poll_list and trigger NET_RX_SOFTIRQ on new cpu.

2011-06-06ipvs: restore support for iptables SNATJulian Anastasov
Fix the IPVS priority in LOCAL_IN hook, so that SNAT target in POSTROUTING is supported for IPVS traffic as in 2.6.36 where it worked depending on module load order. Before 2.6.37 we used priority 100 in LOCAL_IN to process remote requests. We used the same priority as iptables SNAT and if IPVS handlers are installed before SNAT handlers we supported SNAT in POSTROUTING for the IPVS traffic. If SNAT is installed before IPVS, the netfilter handlers are before IPVS and netfilter checks the NAT table twice for the IPVS requests: once in LOCAL_IN where IPS_SRC_NAT_DONE is set and second time in POSTROUTING where the SNAT rules are ignored because IPS_SRC_NAT_DONE was already set in LOCAL_IN. But in 2.6.37 we changed the IPVS priority for LOCAL_IN with the goal to be unique (101) forgetting the fact that for IPVS traffic we should not walk both LOCAL_IN and POSTROUTING nat tables. So, change the priority for processing remote IPVS requests from 101 to 99, i.e. before NAT_SRC (100) because we prefer to support SNAT in POSTROUTING instead of LOCAL_IN. It also moves the priority for IPVS replies from 99 to 98. Use constants instead of magic numbers at these places.
