      pull request (net): ipsec 2015-10-22
      
      1) Fix IPsec pre-encap fragmentation for GSO packets.
         From Herbert Xu.
      
      2) Fix some header checks in _decode_session6.
         We skip the header informations if the data pointer points
         already behind the header in question for some protocols.
         This is because we call pskb_may_pull with a negative value
         converted to unsigened int from pskb_may_pull in this case.
         Skipping the header informations can lead to incorrect policy
         lookups. From Mathias Krause.
      
      3) Allow to change the replay threshold and expiry timer of a
         state without having to set other attributes like replay
         counter and byte lifetime. Changing these other attributes
         may break the SA. From Michael Rossberg.
      
      4) Fix pmtu discovery for local generated packets.
         We may fail dispatch to the inner address family.
         As a reault, the local error handler is not called
         and the mtu value is not reported back to userspace.
      
      Please pull or let me know if there are problems.

      net: ipv6: Dont add RT6_LOOKUP_F_IFACE flag if saddr set · d46a9d67
      David Ahern authored
      741a11d9 ("net: ipv6: Add RT6_LOOKUP_F_IFACE flag if oif is set")
      adds the RT6_LOOKUP_F_IFACE flag to make device index mismatch fatal if
      oif is given. Hajime reported that this change breaks the Mobile IPv6
      use case that wants to force the message through one interface yet use
      the source address from another interface. Handle this case by only
      adding the flag if oif is set and saddr is not set.

      mISDN: fix OOM condition for sending queued I-Frames · c96356a9
      Karsten Keil authored
      The old code did not check the return value of skb_clone().
      The extra skb_clone() is not needed at all, if using skb_realloc_headroom()
      instead, which gives us a private copy with enough headroom as well.
      We need to requeue the original skb if the call failed, because we cannot
      inform upper layers about the data loss. Restructure the code to minimise
      rollback effort if it happens.

      The skb_clone() return value was not checked and the skb_realloc_headroom()

      VSOCK: sock_put wasn't safe to call in interrupt context · 4ef7ea91
      Jorgen Hansen authored
      In the vsock vmci_transport driver, sock_put wasn't safe to call
      in interrupt context, since that may call the vsock destructor
      which in turn calls several functions that should only be called
      from process context. This change defers the callling of these
      functions  to a worker thread. All these functions were
      deallocation of resources related to the transport itself.
      
      Furthermore, an unused callback was removed to simplify the
      cleanup.
      
      Multiple customers have been hitting this issue when using
      VMware tools on vSphere 2015.
      
      Also added a version to the vmci transport module (starting from
      1.0.2.0-k since up until now it appears that this module was
      sharing version with vsock that is currently at 1.0.1.0-k).

      netlink: fix locking around NETLINK_LIST_MEMBERSHIPS · 47191d65
      David Herrmann authored
      Currently, NETLINK_LIST_MEMBERSHIPS grabs the netlink table while copying
      the membership state to user-space. However, grabing the netlink table is
      effectively a write_lock_irq(), and as such we should not be triggering
      page-faults in the critical section.
      
      This can be easily reproduced by the following snippet:
          int s = socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE);
          void *p = mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0);
          int r = getsockopt(s, 0x10e, 9, p, (void*)((char*)p + 4092));
      
      This should work just fine, but currently triggers EFAULT and a possible
      WARN_ON below handle_mm_fault().
      
      Fix this by reducing locking of NETLINK_LIST_MEMBERSHIPS to a read-side
      lock. The write-lock was overkill in the first place, and the read-lock
      allows page-faults just fine.

      openvswitch: Serialize nested ct actions if provided · e754ec69
      Joe Stringer authored
      If userspace provides a ct action with no nested mark or label, then the
      storage for these fields is zeroed. Later when actions are requested,
      such zeroed fields are serialized even though userspace didn't
      originally specify them. Fix the behaviour by ensuring that no action is
      serialized in this case, and reject actions where userspace attempts to
      set these fields with mask=0. This should make netlink marshalling
      consistent across deserialization/reserialization.

      tipc: conditionally expand buffer headroom over udp tunnel · e5356794
      Jon Paul Maloy authored
      In commit d999297c ("tipc: reduce locking scope during packet reception")
      we altered the packet retransmission function. Since then, when
      restransmitting packets, we create a clone of the original buffer
      using __pskb_copy(skb, MIN_H_SIZE), where MIN_H_SIZE is the size of
      the area we want to have copied, but also the smallest possible TIPC
      packet size. The value of MIN_H_SIZE is 24.
      
      Unfortunately, __pskb_copy() also has the effect that the headroom
      of the cloned buffer takes the size MIN_H_SIZE. This is too small
      for carrying the packet over the UDP tunnel bearer, which requires
      a minimum headroom of 28 bytes. A change to just use pskb_copy()
      lets the clone inherit the original headroom of 80 bytes, but also
      assumes that the copied data area is of at least that size, something
      that is not always the case. So that is not a viable solution.
      
      We now fix this by adding a check for sufficient headroom in the
      transmit function of udp_media.c, and expanding it when necessary.

      tipc: allow non-linear first fragment buffer · 45c8b7b1
      Jon Paul Maloy authored
      The current code for message reassembly is erroneously assuming that
      the the first arriving fragment buffer always is linear, and then goes
      ahead resetting the fragment list of that buffer in anticipation of
      more arriving fragments.
      
      However, if the buffer already happens to be non-linear, we will
      inadvertently drop the already attached fragment list, and later
      on trig a BUG() in __pskb_pull_tail().
      
      We see this happen when running fragmented TIPC multicast across UDP,
      something made possible since
      commit d0f91938 ("tipc: add ip/udp media type")
      
      We fix this by not resetting the fragment list when the buffer is non-
      linear, and by initiatlizing our private fragment list tail pointer to
      the tail of the existing fragment list.

      James Morse authored
      "openvswitch: Remove vport stats" removed the per-vport statistics, in
      order to use the netdev's statistics fields.
      "openvswitch: Fix ovs_vport_get_stats()" fixed the export of these stats
      to user-space, by using the provided netdev_ops to collate them - but ovs
      internal devices still use an unallocated dev->tstats field to count
      packets, which are no longer exported by this api.
      
      Allocate the dev->tstats field for ovs internal devices, and wire up
      ndo_get_stats64 with the original implementation of
      ovs_vport_get_stats().
      
      On its own, "openvswitch: Fix ovs_vport_get_stats()" fixes the OOPs,

      tipc: extend broadcast link window size · 53387c4e
      Jon Paul Maloy authored
      The default fix broadcast window size is currently set to 20 packets.
      This is a very low value, set at a time when we were still testing on
      10 Mb/s hubs, and a change to it is long overdue.
      
      Commit 7845989c ("net: tipc: fix stall during bclink wakeup procedure")
      revealed a problem with this low value. For messages of importance LOW,
      the backlog queue limit will be  calculated to 30 packets, while a
      single, maximum sized message of 66000 bytes, carried across a 1500 MTU
      network consists of 46 packets.
      
      This leads to the following scenario (among others leading to the same
      situation):
      
      1: Msg 1 of 46 packets is sent. 20 packets go to the transmit queue, 26
         packets to the backlog queue.
      2: Msg 2 of 46 packets is attempted sent, but rejected because there is
         no more space in the backlog queue at this level. The sender is added
         to the wakeup queue with a "pending packets chain size" number of 46.
      3: Some packets in the transmit queue are acked and released. We try to
         wake up the sender, but the pending size of 46 is bigger than the LOW
         wakeup limit of 30, so this doesn't happen.
      5: Subsequent acks releases all the remaining buffers. Each time we test
         for the wakeup criteria and find that 46 still is larger than 30,
         even after both the transmit and the backlog queues are empty.
      6: The sender is never woken up and given a chance to send its message.
         He is stuck.
      
      We could now loosen the wakeup criteria (used by link_prepare_wakeup())
      to become equal to the send criteria (used by tipc_link_xmit()), i.e.,
      by ignoring the "pending packets chain size" value altogether, or we can
      just increase the queue limits so that the criteria can be satisfied
      anyway. There are good reasons (potentially multiple waiting senders) to
      not opt for the former solution, so we choose the latter one.
      
      This commit fixes the problem by giving the broadcast link window a
      default value of 50 packets. We also introduce a new minimum link
      window size BCLINK_MIN_WIN of 32, which is enough to always avoid the
      described situation. Finally, in order to not break any existing users
      which may set the window explicitly, we enforce that the window is set
      to the new minimum value in case the user is trying to set it to
      anything lower.

      xfrm: Fix pmtu discovery for local generated packets. · ca064bd8
      Steffen Klassert authored
      Commit 044a832a ("xfrm: Fix local error reporting crash
      with interfamily tunnels") moved the setting of skb->protocol
      behind the last access of the inner mode family to fix an
      interfamily crash. Unfortunately now skb->protocol might not
      be set at all, so we fail dispatch to the inner address family.
      As a reault, the local error handler is not called and the
      mtu value is not reported back to userspace.
      
      We fix this by setting skb->protocol on message size errors
      before we call xfrm_local_error.

      net: bcmgenet: Fix early link interrupt enabling · 37850e37
      Florian Fainelli authored
      Link interrupts are enabled in init_umac(), which is too early for us to
      process them since we do not yet have a valid PHY device pointer. On
      BCM7425 chips for instance, we will crash calling phy_mac_interrupt()
      because phydev is NULL.
      
      Fix this by moving the link interrupts enabling in
      bcmgenet_netif_start(), under a specific function:
      bcmgenet_link_intr_enable() and while at it, update the comments
      surrounding the code.
