      ixgbevf: ixgbevf_write/read_posted_mbx should use IXGBE_ERR_MBX to initialize ret_val · b3a3c517
      Xin Long authored
      
      
      Now ixgbevf_write/read_posted_mbx use -IXGBE_ERR_MBX as the initiative
      return value, but it's incorrect, cause in ixgbevf_vlan_rx_add_vid(),
      it use err == IXGBE_ERR_MBX, the err returned from mac.ops.set_vfta,
      and in ixgbevf_set_vfta_vf, it return from write/read_posted. so we
      should initialize err with IXGBE_ERR_MBX, instead of -IXGBE_ERR_MBX.
      
      With this fix, the other functions that called it also can work well,
      cause they only care about if err is 0 or not.

      e1000e: keep Rx/Tx HW_VLAN_CTAG in sync · 83808641

      The bit in the e1000 driver that mentions explicitly that the hardware
      has no support for separate RX/TX VLAN accel toggling rings true for
      e1000e as well, and thus both NETIF_F_HW_VLAN_CTAG_RX and
      NETIF_F_HW_VLAN_CTAG_TX need to be kept in sync.
      
      Revert a portion of commit 889ad456
      
       ("e1000e: keep VLAN interfaces
      functional after rxvlan off") since keeping the bits in sync resolves

      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.

      qed: Protect the doorbell BAR with the write barriers. · 34c7bb47
      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.

      bpf, perf: delay release of BPF prog after grace period · ceb56070
      Daniel Borkmann authored
      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).

      net: bridge: fix vlan stats continue counter · 565ce8f3
      Nikolay Aleksandrov authored
      I made a dumb off-by-one mistake when I added the vlan stats counter
      dumping code. The increment should happen before the check, not after
      otherwise we miss one entry when we continue dumping.

      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 !
