      the right place is destroy_super().  As it is, we leak them if sget()

      anybody) isn't needed and should be freed.

      pkt_sched: fq: rate limiting improvements · 0eab5eb7
      Eric Dumazet authored
      FQ rate limiting suffers from two problems, reported
      by Steinar :
      
      1) FQ enforces a delay when flow quantum is exhausted in order
      to reduce cpu overhead. But if packets are small, current
      delay computation is slightly wrong, and observed rates can
      be too high.
      
      Steinar had this problem because he disabled TSO and GSO,
      and default FQ quantum is 2*1514.
      
      (Of course, I wish recent TSO auto sizing changes will help
      to not having to disable TSO in the first place)
      
      2) maxrate was not used for forwarded flows (skbs not attached
      to a socket)
      
      Tested:
      
      tc qdisc add dev eth0 root est 1sec 4sec fq maxrate 8Mbit
      netperf -H lpq84 -l 1000 &
      sleep 10 ; tc -s qdisc show dev eth0

      ip_tunnel: Remove double unregister of the fallback device · cfe4a536
      Steffen Klassert authored
      When queueing the netdevices for removal, we queue the
      fallback device twice in ip_tunnel_destroy(). The first
      time when we queue all netdevices in the namespace and
      then again explicitly. Fix this by removing the explicit
      queueing of the fallback device.
      
      Bug was introduced when network namespace support was added
      with commit 6c742e71 ("ipip: add x-netns support").

      * Fix possible memory access race in the lblc and lblcr schedulers,
        introduced when it was converted to use RCU, two patches from
        Julian Anastasov.
      
      * Fix hard dependency on CPU 0 when reading per-cpu stats in the
        rate estimator, from Julian Anastasov.
      
      * Fix race that may lead to object use after release, when invoking
        ipvsadm -C && ipvsadm -R, introduced when adding RCU, from Julian
        Anastasov.

      ll_temac: Reset dma descriptors indexes on ndo_open · 7167cf0e
      Ricardo Ribalda authored
      The dma descriptors indexes are only initialized on the probe function.
      
      If a packet is on the buffer when temac_stop is called, the dma
      descriptors indexes can be left on a incorrect state where no other
      package can be sent.
      
      So an interface could be left in an usable state after ifdow/ifup.
      
      This patch makes sure that the descriptors indexes are in a proper
      status when the device is open.

      ipv6 mcast: use in6_dev_put in timer handlers instead of __in6_dev_put · 9260d3e1

      ipv6: gre: correct calculation of max_headroom · 3da812d8
      Hannes Frederic Sowa authored
      gre_hlen already accounts for sizeof(struct ipv6_hdr) + gre header,
      so initialize max_headroom to zero. Otherwise the
      
      	if (encap_limit >= 0) {
      		max_headroom += 8;
      		mtu -= 8;
      	}
      
      increments an uninitialized variable before max_headroom was reset.

      powerpc/83xx: gianfar_ptp: select 1588 clock source through dts file · e58f6f4f
      Aida Mynzhasova authored
      Currently IEEE 1588 timer reference clock source is determined through
      hard-coded value in gianfar_ptp driver. This patch allows to select ptp
      clock source by means of device tree file node.
      
      For instance:
      
      	fsl,cksel = <0>;
      
      for using external (TSEC_TMR_CLK input) high precision timer
      reference clock.
      
      Other acceptable values:
      
      	<1> : eTSEC system clock
      	<2> : eTSEC1 transmit clock
      	<3> : RTC clock input
      
      When this attribute isn't used, eTSEC system clock will serve as
      IEEE 1588 timer reference clock.

      bonding: Fix broken promiscuity reference counting issue · 5a0068de
      Neil Horman authored
      Recently grabbed this report:
      https://bugzilla.redhat.com/show_bug.cgi?id=1005567
      
      Of an issue in which the bonding driver, with an attached vlan encountered the
      following errors when bond0 was taken down and back up:
      
      dummy1: promiscuity touches roof, set promiscuity failed. promiscuity feature of
      device might be broken.
      
      The error occurs because, during __bond_release_one, if we release our last
      slave, we take on a random mac address and issue a NETDEV_CHANGEADDR
      notification.  With an attached vlan, the vlan may see that the vlan and bond
      mac address were in sync, but no longer are.  This triggers a call to dev_uc_add
      and dev_set_rx_mode, which enables IFF_PROMISC on the bond device.  Then, when
      we complete __bond_release_one, we use the current state of the bond flags to
      determine if we should decrement the promiscuity of the releasing slave.  But
      since the bond changed promiscuity state during the release operation, we
      incorrectly decrement the slave promisc count when it wasn't in promiscuous mode
      to begin with, causing the above error
      
      Fix is pretty simple, just cache the bonding flags at the start of the function
      and use those when determining the need to set promiscuity.
      
      This is also needed for the ALLMULTI flag

      tcp: TSQ can use a dynamic limit · c9eeec26
      Eric Dumazet authored
      When TCP Small Queues was added, we used a sysctl to limit amount of
      packets queues on Qdisc/device queues for a given TCP flow.
      
      Problem is this limit is either too big for low rates, or too small
      for high rates.
      
      Now TCP stack has rate estimation in sk->sk_pacing_rate, and TSO
      auto sizing, it can better control number of packets in Qdisc/device
      queues.
      
      New limit is two packets or at least 1 to 2 ms worth of packets.
      
      Low rates flows benefit from this patch by having even smaller
      number of packets in queues, allowing for faster recovery,
      better RTT estimations.
      
      High rates flows benefit from this patch by allowing more than 2 packets
      in flight as we had reports this was a limiting factor to reach line
      rate. [ In particular if TX completion is delayed because of coalescing
      parameters ]
      
      Example for a single flow on 10Gbp link controlled by FQ/pacing
      
      14 packets in flight instead of 2
      
      $ tc -s -d qd
      qdisc fq 8001: dev eth0 root refcnt 32 limit 10000p flow_limit 100p
      buckets 1024 quantum 3028 initial_quantum 15140
       Sent 1168459366606 bytes 771822841 pkt (dropped 0, overlimits 0
      requeues 6822476)
       rate 9346Mbit 771713pps backlog 953820b 14p requeues 6822476
        2047 flow, 2046 inactive, 1 throttled, delay 15673 ns
        2372 gc, 0 highprio, 0 retrans, 9739249 throttled, 0 flows_plimit
      
      Note that sk_pacing_rate is currently set to twice the actual rate, but
      this might be refined in the future when a flow is in congestion
      avoidance.
      
      Additional change : skb->destructor should be set to tcp_wfree().
      
      A future patch (for linux 3.13+) might remove tcp_limit_output_bytes
