2016-02-06tipc: fix connection abort during subscription cancellationParthasarathy Bhuvaragan
In 'commit 7fe8097cef5f ("tipc: fix nullpointer bug when subscribing to events")', we terminate the connection if the subscription creation fails. In the same commit, the subscription creation result was based on the value of subscription pointer (set in the function) instead of the return code. Unfortunately, the same function also handles subscription cancellation request. For a subscription cancellation request, the subscription pointer cannot be set. Thus the connection is terminated during cancellation request. In this commit, we move the subcription cancel check outside of tipc_subscrp_create(). Hence, - tipc_subscrp_create() will create a subscripton - tipc_subscrb_rcv_cb() will subscribe or cancel a subscription.

2016-02-06tipc: introduce tipc_subscrb_subscribe() routineParthasarathy Bhuvaragan
In this commit, we split tipc_subscrp_create() into two: 1. tipc_subscrp_create() creates a subscription 2. A new function tipc_subscrp_subscribe() adds the subscription to the subscriber subscription list, activates the subscription timer and subscribes to the nametable updates. In future commits, the purpose of tipc_subscrb_rcv_cb() will be to either subscribe or cancel a subscription. There is no functional change in this commit.

2016-02-06tipc: remove struct tipc_name_seq from struct tipc_subscriptionParthasarathy Bhuvaragan
Until now, struct tipc_subscriber has duplicate fields for type, upper and lower (as member of struct tipc_name_seq) at: 1. as member seq in struct tipc_subscription 2. as member seq in struct tipc_subscr, which is contained in struct tipc_event The former structure contains the type, upper and lower values in network byte order and the later contains the intact copy of the request. The struct tipc_subscription contains a field swap to determine if request needs network byte order conversion. Thus by using swap, we can convert the request when required instead of duplicating it. In this commit, 1. we remove the references to these elements as members of struct tipc_subscription and replace them with elements from struct tipc_subscr. 2. provide new functions to convert the user request into network byte order.

2016-02-06tipc: remove incorrect check for subscription timeout valueParthasarathy Bhuvaragan
Until now, during subscription creation we set sub->timeout by converting the timeout request value in milliseconds to jiffies. This is followed by setting the timeout value in the timer if sub->timeout != TIPC_WAIT_FOREVER. For a subscription create request with a timeout value of TIPC_WAIT_FOREVER, msecs_to_jiffies(TIPC_WAIT_FOREVER) returns MAX_JIFFY_OFFSET (0xfffffffe). This is not equal to TIPC_WAIT_FOREVER (0xffffffff). In this commit, we remove this check.

2016-02-06tcp: do not enqueue skb with SYN flagEric Dumazet
If we remove the SYN flag from the skbs that tcp_fastopen_add_skb() places in socket receive queue, then we can remove the test that tcp_recvmsg() has to perform in fast path. All we have to do is to adjust SEQ in the slow path. For the moment, we place an unlikely() and output a message if we find an skb having SYN flag set. Goal would be to get rid of the test completely.

2016-02-06tcp: fastopen: accept data/FIN present in SYNACK messageEric Dumazet
RFC 7413 (TCP Fast Open) 4.2.2 states that the SYNACK message MAY include data and/or FIN This patch adds support for the client side : If we receive a SYNACK with payload or FIN, queue the skb instead of ignoring it. Since we already support the same for SYN, we refactor the existing code and reuse it. Note we need to clone the skb, so this operation might fail under memory pressure. Sara Dickinson pointed out FreeBSD server Fast Open implementation was planned to generate such SYNACK in the future. The server side might be implemented on linux later.

2016-02-06tipc: fix link attribute propagation bugRichard Alpe
Changing certain link attributes (link tolerance and link priority) from the TIPC management tool is supposed to automatically take effect at both endpoints of the affected link. Currently the media address is not instantiated for the link and is used uninstantiated when crafting protocol messages designated for the peer endpoint. This means that changing a link property currently results in the property being changed on the local machine but the protocol message designated for the peer gets lost. Resulting in property discrepancy between the endpoints. In this patch we resolve this by using the media address from the link entry and using the bearer transmit function to send it. Hence, we can now eliminate the redundant function tipc_link_prot_xmit() and the redundant field tipc_link::media_addr.

2016-02-02mac80211: minstrel: Change expected throughput unit back to KbpsSven Eckelmann
The change from cur_tp to the function minstrel_get_tp_avg/minstrel_ht_get_tp_avg changed the unit used for the current throughput. For example in minstrel_ht the correct conversion between them would be: mrs->cur_tp / 10 == minstrel_ht_get_tp_avg(..). This factor 10 must also be included in the calculation of minstrel_get_expected_throughput and minstrel_ht_get_expected_throughput to return values with the unit [Kbps] instead of [10Kbps]. Otherwise routing algorithms like B.A.T.M.A.N. V will make incorrect decision based on these values. Its kernel based implementation expects expected_throughput always to have the unit [Kbps] and not sometimes [10Kbps] and sometimes [Kbps]. The same requirement has iw or olsrdv2's nl80211 based statistics module which retrieve the same data via NL80211_STA_INFO_TX_BITRATE.
