      batman-adv: release vlan object after checking the CRC · 91c2b1a9
      Antonio Quartulli authored
      There is a refcounter unbalance in the CRC checking routine
      invoked on OGM reception. A vlan object is retrieved (thus
      its refcounter is increased by one) but it is never properly
      released. This leads to a memleak because the vlan object
      will never be free'd.
      
      Fix this by releasing the vlan object after having read the
      CRC.

      batman-adv: fix TT-TVLV parsing on OGM reception · e889241f
      Antonio Quartulli authored
      When accessing a TT-TVLV container in the OGM RX path
      the variable pointing to the list of changes to apply is
      altered by mistake.
      
      This makes the TT component read data at the wrong position
      in the OGM packet buffer.
      
      Fix it by removing the bogus pointer alteration.

      batman-adv: fix soft-interface MTU computation · 930cd6e4
      Antonio Quartulli authored
      The current MTU computation always returns a value
      smaller than 1500bytes even if the real interfaces
      have an MTU large enough to compensate the batman-adv
      overhead.
      
      Fix the computation by properly returning the highest
      admitted value.

      packet: check for ndo_select_queue during queue selection · 0fd5d57b
      Daniel Borkmann authored
      Mathias reported that on an AMD Geode LX embedded board (ALiX)
      with ath9k driver PACKET_QDISC_BYPASS, introduced in commit
      d346a3fa ("packet: introduce PACKET_QDISC_BYPASS socket
      option"), triggers a WARN_ON() coming from the driver itself
      via 066dae93 ("ath9k: rework tx queue selection and fix
      queue stopping/waking").
      
      The reason why this happened is that ndo_select_queue() call
      is not invoked from direct xmit path i.e. for ieee80211 subsystem
      that sets queue and TID (similar to 802.1d tag) which is being
      put into the frame through 802.11e (WMM, QoS). If that is not
      set, pending frame counter for e.g. ath9k can get messed up.
      
      So the WARN_ON() in ath9k is absolutely legitimate. Generally,
      the hw queue selection in ieee80211 depends on the type of
      traffic, and priorities are set according to ieee80211_ac_numbers
      mapping; working in a similar way as DiffServ only on a lower
      layer, so that the AP can favour frames that have "real-time"
      requirements like voice or video data frames.
      
      Therefore, check for presence of ndo_select_queue() in netdev
      ops and, if available, invoke it with a fallback handler to
      __packet_pick_tx_queue(), so that driver such as bnx2x, ixgbe,
      or mlx4 can still select a hw queue for transmission in
      relation to the current CPU while e.g. ieee80211 subsystem
      can make their own choices.

      netdevice: add queue selection fallback handler for ndo_select_queue · 99932d4f
      Daniel Borkmann authored
      Add a new argument for ndo_select_queue() callback that passes a
      fallback handler. This gets invoked through netdev_pick_tx();
      fallback handler is currently __netdev_pick_tx() as most drivers
      invoke this function within their customized implementation in
      case for skbs that don't need any special handling. This fallback
      handler can then be replaced on other call-sites with different
      queue selection methods (e.g. in packet sockets, pktgen etc).
      
      This also has the nice side-effect that __netdev_pick_tx() is
      then only invoked from netdev_pick_tx() and export of that
      function to modules can be undone.

      net: sctp: Fix a_rwnd/rwnd management to reflect real state of the receiver's buffer · ef2820a7
      Matija Glavinic Pecotic authored
      Implementation of (a)rwnd calculation might lead to severe performance issues
      and associations completely stalling. These problems are described and solution
      is proposed which improves lksctp's robustness in congestion state.
      
      1) Sudden drop of a_rwnd and incomplete window recovery afterwards
      
      Data accounted in sctp_assoc_rwnd_decrease takes only payload size (sctp data),
      but size of sk_buff, which is blamed against receiver buffer, is not accounted
      in rwnd. Theoretically, this should not be the problem as actual size of buffer
      is double the amount requested on the socket (SO_RECVBUF). Problem here is
      that this will have bad scaling for data which is less then sizeof sk_buff.
      E.g. in 4G (LTE) networks, link interfacing radio side will have a large portion
      of traffic of this size (less then 100B).
      
      An example of sudden drop and incomplete window recovery is given below. Node B
      exhibits problematic behavior. Node A initiates association and B is configured
      to advertise rwnd of 10000. A sends messages of size 43B (size of typical sctp
      message in 4G (LTE) network). On B data is left in buffer by not reading socket
      in userspace.
      
      Lets examine when we will hit pressure state and declare rwnd to be 0 for
      scenario with above stated parameters (rwnd == 10000, chunk size == 43, each
      chunk is sent in separate sctp packet)
      
      Logic is implemented in sctp_assoc_rwnd_decrease:
      
      socket_buffer (see below) is maximum size which can be held in socket buffer
      (sk_rcvbuf). current_alloced is amount of data currently allocated (rx_count)
      
      A simple expression is given for which it will be examined after how many
      packets for above stated parameters we enter pressure state:
      
      We start by condition which has to be met in order to enter pressure state:
      
      	socket_buffer < currently_alloced;
      
      currently_alloced is represented as size of sctp packets received so far and not
      yet delivered to userspace. x is the number of chunks/packets (since there is no
      bundling, and each chunk is delivered in separate packet, we can observe each
      chunk also as sctp packet, and what is important here, having its own sk_buff):
      
      	socket_buffer < x*each_sctp_packet;
      
      each_sctp_packet is sctp chunk size + sizeof(struct sk_buff). socket_buffer is
      twice the amount of initially requested size of socket buffer, which is in case
      of sctp, twice the a_rwnd requested:
      
      	2*rwnd < x*(payload+sizeof(struc sk_buff));
      
      sizeof(struct sk_buff) is 190 (3.13.0-rc4+). Above is stated that rwnd is 10000
      and each payload size is 43
      
      	20000 < x(43+190);
      
      	x > 20000/233;
      
      	x ~> 84;
      
      After ~84 messages, pressure state is entered and 0 rwnd is advertised while
      received 84*43B ~= 3612B sctp data. This is why external observer notices sudden
      drop from 6474 to 0, as it will be now shown in example:

      At this point, rwnd_press stores current rwnd value so it can be later restored
      in sctp_assoc_rwnd_increase. This however doesn't happen as condition to start
      slowly increasing rwnd until rwnd_press is returned to rwnd is never met. This
      condition is not met since rwnd, after it hit 0, must first reach rwnd_press by
      adding amount which is read from userspace. Let us observe values in above
      example. Initial a_rwnd is 10000, pressure was hit when rwnd was ~6500 and the
      amount of actual sctp data currently waiting to be delivered to userspace
      is ~3500. When userspace starts to read, sctp_assoc_rwnd_increase will be blamed
      only for sctp data, which is ~3500. Condition is never met, and when userspace
      reads all data, rwnd stays on 3569.

      Reproduction is straight forward, it is enough for sender to send packets of
      size less then sizeof(struct sk_buff) and receiver keeping them in its buffers.
      
      2) Minute size window for associations sharing the same socket buffer
      
      In case multiple associations share the same socket, and same socket buffer
      (sctp.rcvbuf_policy == 0), different scenarios exist in which congestion on one
      of the associations can permanently drop rwnd of other association(s).
      
      Situation will be typically observed as one association suddenly having rwnd
      dropped to size of last packet received and never recovering beyond that point.
      Different scenarios will lead to it, but all have in common that one of the
      associations (let it be association from 1)) nearly depleted socket buffer, and
      the other association blames socket buffer just for the amount enough to start
      the pressure. This association will enter pressure state, set rwnd_press and
      announce 0 rwnd.
      When data is read by userspace, similar situation as in 1) will occur, rwnd will
      increase just for the size read by userspace but rwnd_press will be high enough
      so that association doesn't have enough credit to reach rwnd_press and restore
      to previous state. This case is special case of 1), being worse as there is, in
      the worst case, only one packet in buffer for which size rwnd will be increased.
      Consequence is association which has very low maximum rwnd ('minute size', in
      our case down to 43B - size of packet which caused pressure) and as such
      unusable.
      
      Scenario happened in the field and labs frequently after congestion state (link
      breaks, different probabilities of packet drop, packet reordering) and with
      scenario 1) preceding. Here is given a deterministic scenario for reproduction:
      
      >From node A establish two associations on the same socket, with rcvbuf_policy
      being set to share one common buffer (sctp.rcvbuf_policy == 0). On association 1
      repeat scenario from 1), that is, bring it down to 0 and restore up. Observe
      scenario 1). Use small payload size (here we use 43). Once rwnd is 'recovered',
      bring it down close to 0, as in just one more packet would close it. This has as
      a consequence that association number 2 is able to receive (at least) one more
      packet which will bring it in pressure state. E.g. if association 2 had rwnd of
      10000, packet received was 43, and we enter at this point into pressure,
      rwnd_press will have 9957. Once payload is delivered to userspace, rwnd will
      increase for 43, but conditions to restore rwnd to original state, just as in
      1), will never be satisfied.

      A careful reader might wonder why it is necessary to reproduce 1) prior
      reproduction of 2). It is simply easier to observe when to send packet over
      association 2 which will push association into the pressure state.
      
      Proposed solution:
      
      Both problems share the same root cause, and that is improper scaling of socket
      buffer with rwnd. Solution in which sizeof(sk_buff) is taken into concern while
      calculating rwnd is not possible due to fact that there is no linear
      relationship between amount of data blamed in increase/decrease with IP packet
      in which payload arrived. Even in case such solution would be followed,
      complexity of the code would increase. Due to nature of current rwnd handling,
      slow increase (in sctp_assoc_rwnd_increase) of rwnd after pressure state is
      entered is rationale, but it gives false representation to the sender of current
      buffer space. Furthermore, it implements additional congestion control mechanism
      which is defined on implementation, and not on standard basis.
      
      Proposed solution simplifies whole algorithm having on mind definition from rfc:
      
      o  Receiver Window (rwnd): This gives the sender an indication of the space
         available in the receiver's inbound buffer.
      
      Core of the proposed solution is given with these lines:
      
      sctp_assoc_rwnd_update:
      	if ((asoc->base.sk->sk_rcvbuf - rx_count) > 0)
      		asoc->rwnd = (asoc->base.sk->sk_rcvbuf - rx_count) >> 1;
      	else
      		asoc->rwnd = 0;
      
      We advertise to sender (half of) actual space we have. Half is in the braces
      depending whether you would like to observe size of socket buffer as SO_RECVBUF
      or twice the amount, i.e. size is the one visible from userspace, that is,
      from kernelspace.
      In this way sender is given with good approximation of our buffer space,
      regardless of the buffer policy - we always advertise what we have. Proposed
      solution fixes described problems and removes necessity for rwnd restoration
      algorithm. Finally, as proposed solution is simplification, some lines of code,
      along with some bytes in struct sctp_association are saved.
      
      Version 2 of the patch addressed comments from Vlad. Name of the function is set
      to be more descriptive, and two parts of code are changed, in one removing the
      superfluous call to sctp_assoc_rwnd_update since call would not result in update
      of rwnd, and the other being reordering of the code in a way that call to
      sctp_assoc_rwnd_update updates rwnd. Version 3 corrected change introduced in v2
      in a way that existing function is not reordered/copied in line, but it is
      correctly called. Thanks Vlad for suggesting.

      ipv4: distinguish EHOSTUNREACH from the ENETUNREACH · cd0f0b95
      Duan Jiong authored
      since commit 251da413("ipv4: Cache ip_error() routes even when not forwarding."),
      the counter IPSTATS_MIB_INADDRERRORS can't work correctly, because the value of
      err was always set to ENETUNREACH.

      Without this patch, the "cat /sys/class/net/ethN/operstate" shows
      "unknown", and "ethtool ethN" shows "Link detected: yes", when VM
      boots up with or without vNIC connected.
      
      This patch fixed the problem.

      dccp: re-enable debug macro · 09db3080
      Gerrit Renker authored
      dccp tfrc: revert
      
      This reverts 6aee49c5 ("dccp: make local variable static") since
      the variable tfrc_debug is referenced by the tfrc_pr_debug(fmt, ...)
      macro when TFRC debugging is enabled. If it is enabled, use of the
      macro produces a compilation error.
