      openvswitch: fix conntrack netlink event delivery · d913d3a7
      Samuel Gauthier authored
      Only the first and last netlink message for a particular conntrack are
      actually sent. The first message is sent through nf_conntrack_confirm when
      the conntrack is committed. The last one is sent when the conntrack is
      destroyed on timeout. The other conntrack state change messages are not
      advertised.
      
      When the conntrack subsystem is used from netfilter, nf_conntrack_confirm
      is called for each packet, from the postrouting hook, which in turn calls
      nf_ct_deliver_cached_events to send the state change netlink messages.
      
      This commit fixes the problem by calling nf_ct_deliver_cached_events in the
      non-commit case as well.

      Sudarsana Reddy Kalluru authored
      SPQ doorbell is currently protected with the compilation barrier. Under the
      stress scenarios, we may get into a state where (due to the weak ordering)
      several ramrod doorbells were written to the BAR with an out-of-order
      producer values. Need to change the barrier type to a write barrier to make
      sure that the write buffer is flushed after each doorbell.

      neigh: Explicitly declare RCU-bh read side critical section in neigh_xmit() · b560f03d
      David Barroso authored
      neigh_xmit() expects to be called inside an RCU-bh read side critical
      section, and while one of its two current callers gets this right, the
      other one doesn't.
      
      More specifically, neigh_xmit() has two callers, mpls_forward() and
      mpls_output(), and while both callers call neigh_xmit() under
      rcu_read_lock(), this provides sufficient protection for neigh_xmit()
      only in the case of mpls_forward(), as that is always called from
      softirq context and therefore doesn't need explicit BH protection,
      while mpls_output() can be called from process context with softirqs
      enabled.
      
      When mpls_output() is called from process context, with softirqs
      enabled, we can be preempted by a softirq at any time, and RCU-bh
      considers the completion of a softirq as signaling the end of any
      pending read-side critical sections, so if we do get a softirq
      while we are in the part of neigh_xmit() that expects to be run inside
      an RCU-bh read side critical section, we can end up with an unexpected
      RCU grace period running right in the middle of that critical section,
      making things go boom.
      
      This patch fixes this impedance mismatch in the callee, by making
      neigh_xmit() always take rcu_read_{,un}lock_bh() around the code that
      expects to be treated as an RCU-bh read side critical section, as this
      seems a safer option than fixing it in the callers.

      e1000e: keep VLAN interfaces functional after rxvlan off · 889ad456
      Jarod Wilson authored
      I've got a bug report about an e1000e interface, where a VLAN interface is
      set up on top of it:
      
      $ ip link add link ens1f0 name ens1f0.99 type vlan id 99
      $ ip link set ens1f0 up
      $ ip link set ens1f0.99 up
      $ ip addr add 192.168.99.92 dev ens1f0.99
      
      At this point, I can ping another host on vlan 99, ip 192.168.99.91.
      However, if I do the following:
      
      $ ethtool -K ens1f0 rxvlan off
      
      Then no traffic passes on ens1f0.99. It comes back if I toggle rxvlan on
      again. I'm not sure if this is actually intended behavior, or if there's a
      lack of software VLAN stripping fallback, or what, but things continue to
      work if I simply don't call e1000e_vlan_strip_disable() if there are
      active VLANs (plagiarizing a function from the e1000 driver here) on the
      interface.
      
      Also slipped a related-ish fix to the kerneldoc text for
      e1000e_vlan_strip_disable here...

      cfg80211: fix proto in ieee80211_data_to_8023 for frames without LLC header · c041778c
      Felix Fietkau authored
      The PDU length of incoming LLC frames is set to the total skb payload size
      in __ieee80211_data_to_8023() of net/wireless/util.c which incorrectly
      includes the length of the IEEE 802.11 header.
      
      The resulting LLC frame header has a too large PDU length, causing the
      llc_fixup_skb() function of net/llc/llc_input.c to reject the incoming
      skb, effectively breaking STP.
      
      Solve the problem by properly substracting the IEEE 802.11 frame header size
      from the PDU length, allowing the LLC processor to pick up the incoming
      control messages.
      
      Special thanks to Gerry Rozema for tracking down the regression and proposing
      a suitable patch.

      Commit dead9f29 ("perf: Fix race in BPF program unregister") moved
      destruction of BPF program from free_event_rcu() callback to __free_event(),
      which is problematic if used with tail calls: if prog A is attached as
      trace event directly, but at the same time present in a tail call map used
      by another trace event program elsewhere, then we need to delay destruction
      via RCU grace period since it can still be in use by the program doing the
      tail call (the prog first needs to be dropped from the tail call map, then
      trace event with prog A attached destroyed, so we get immediate destruction).

      tcp: do not send too big packets at retransmit time · a3d2e9f8
      Eric Dumazet authored
      Arjun reported a bug in TCP stack and bisected it to a recent commit.
      
      In case where we process SACK, we can coalesce multiple skbs
      into fat ones (tcp_shift_skb_data()), to lower write queue
      overhead, because we do not expect to retransmit these packets.
      
      However, SACK reneging can happen, forcing the sender to retransmit
      all these packets. If skb->len is above 64KB, we then send buggy
      IP packets that could hang TSO engine on cxgb4.
      
      Neal suggested to use tcp_tso_autosize() instead of tp->gso_segs
      so that we cook packets of optimal size vs TCP/pacing.
      
      Thanks to Arjun for reporting the bug and running the tests !

      Since we will remove items off the list using list_del() we need
      to use a safe version of the list_for_each() macro aptly named

      Check for SMU RX local/remote faults along with SPU LINK

      at link partner's side. Also due to an issue in BGX it's
      rarely seen that initialization doesn't happen properly
      and SMU RX reports faults with everything fine at SPU.
      This patch tries to reinitialize LMAC to fix it.

      ====================
      batman-adv: Fixes for Linux 4.7
      
      Antonio currently seems to be occupied. This is currently rather unfortunate
      because there are patches waiting in the batman-adv development repository
      maint(enance) branch [1] since up to 6 weeks. I am now getting asked when
      these patches will hit the distribution kernels and therefore decided to
      submit these patches directly to netdev.
      
      The patch from Simon works around the problem that warnings could be triggered
      in the translation table code via packets using a VLAN not configured on the
      target host. This warning was replaced with a rate limited info message.
      
      Ben Hutchings found an superfluous batadv_softif_vlan_put in the error
      handling code of the translation table while he backported the "batman-adv:
      Fix reference counting of vlan object for tt_local_entry" patch to the stable
      kernels. He noticed correctly that this batadv_softif_vlan_put should also
      have been removed by the said patch.
      
      The most requested fix at the moment is related to a double free in the
      translation table code. It is a race condition which mostly happens on systems
      with multiple cores and multiple network interface attached to batman-adv. Two
      Freifunk communities which were haunted by weird crashes (with backtraces
      reporting problems in other parts of the kernel) were kind enough to test this
      patch. They reported that there systems are now running stable after applying
      this patch.
      
      An invalid memory access was detected in the batadv_icmp_packet_rr handling
      code when receiving a skbuff with fragments. The last patch is fixing a memory
      leak when the interface is removed via .dellink. The code to fix it was copied
      from the code handling the legacy sysfs interface to remove netdevices from a
      batman-adv netdevice.
      
      There are still 28 patches in the development tree for v4.8 but I will leave
      them to Antonio because these are cleanups and features and therefore for net-
      next.
