      net: ethernet: ti: am65-cpsw: fix rmii 100Mbit link mode · c2f89219
      Grygorii Strashko authored
      In RMII link mode it's required to set bit 15 IFCTL_A in MAC_SL MAC_CONTROL
      register to enable support for 100Mbit link speed.

      cxgb4: fix thermal zone device registration · 6b6382a8
      Potnuri Bharat Teja authored
      When multiple adapters are present in the system, pci hot-removing second
      adapter leads to the following warning as both the adapters registered
      thermal zone device with same thermal zone name/type.
      Therefore, use unique thermal zone name during thermal zone device
      initialization. Also mark thermal zone dev NULL once unregistered.

      drivers/net/wan/hdlc_cisco: Add hard_header_len · 1a545ebe
      Xie He authored
      This driver didn't set hard_header_len. This patch sets hard_header_len
      for it according to its header_ops->create function.
      
      This driver's header_ops->create function (cisco_hard_header) creates
      a header of (struct hdlc_header), so hard_header_len should be set to
      sizeof(struct hdlc_header).

      ====================
      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for net:
      
      1) Do not delete clash entries on reply, let them expire instead,
         from Florian Westphal.
      
      2) Do not report EAGAIN to nfnetlink, otherwise this enters a busy loop.
         Update nfnetlink_unicast() to translate EAGAIN to ENOBUFS.
      
      3) Remove repeated words in code comments, from Randy Dunlap.
      
      4) Several patches for the flowtable selftests, from Fabian Frederick.

      tipc: fix using smp_processor_id() in preemptible · bb8872a1
      Tuong Lien authored
      The 'this_cpu_ptr()' is used to obtain the AEAD key' TFM on the current
      CPU for encryption, however the execution can be preemptible since it's
      actually user-space context, so the 'using smp_processor_id() in
      preemptible' has been observed.
      
      We fix the issue by using the 'get/put_cpu_ptr()' API which consists of
      a 'preempt_disable()' instead.

      netfilter: conntrack: do not auto-delete clash entries on reply · c4617214
      Florian Westphal authored
      Its possible that we have more than one packet with the same ct tuple
      simultaneously, e.g. when an application emits n packets on same UDP
      socket from multiple threads.
      
      NAT rules might be applied to those packets. With the right set of rules,
      n packets will be mapped to m destinations, where at least two packets end
      up with the same destination.
      
      When this happens, the existing clash resolution may merge the skb that
      is processed after the first has been received with the identical tuple
      already in hash table.
      
      However, its possible that this identical tuple is a NAT_CLASH tuple.
      In that case the second skb will be sent, but no reply can be received
      since the reply that is processed first removes the NAT_CLASH tuple.
      
      Do not auto-delete, this gives a 1 second window for replies to be passed
      back to originator.
      
      Packets that are coming later (udp stream case) will not be affected:
      they match the original ct entry, not a NAT_CLASH one.
      
      Also prevent NAT_CLASH entries from getting offloaded.
      
      Fixes: 6a757c07 ("netfilter: conntrack: allow insertion of clashing entries")
