      Simplest fix seems to add rcu read lock section.

      net: core: 'ethtool' issue with querying phy settings · f96dee13
      Arun Parameswaran authored
      When trying to configure the settings for PHY1, using commands
      like 'ethtool -s eth0 phyad 1 speed 100', the 'ethtool' seems to
      modify other settings apart from the speed of the PHY1, in the
      above case.
      
      The ethtool seems to query the settings for PHY0, and use this
      as the base to apply the new settings to the PHY1. This is
      causing the other settings of the PHY 1 to be wrongly
      configured.
      
      The issue is caused by the '_ethtool_get_settings()' API, which
      gets called because of the 'ETHTOOL_GSET' command, is clearing
      the 'cmd' pointer (of type 'struct ethtool_cmd') by calling
      memset. This clears all the parameters (if any) passed for the
      'ETHTOOL_GSET' cmd. So the driver's callback is always invoked
      with 'cmd->phy_address' as '0'.
      
      The '_ethtool_get_settings()' is called from other files in the
      'net/core'. So the fix is applied to the 'ethtool_get_settings()'
      which is only called in the context of the 'ethtool'.

      bridge: fix parsing of MLDv2 reports · 47cc84ce
      Thadeu Lima de Souza Cascardo authored
      When more than a multicast address is present in a MLDv2 report, all but
      the first address is ignored, because the code breaks out of the loop if
      there has not been an error adding that address.
      
      This has caused failures when two guests connected through the bridge
      tried to communicate using IPv6. Neighbor discoveries would not be
      transmitted to the other guest when both used a link-local address and a
      static address.
      
      This only happens when there is a MLDv2 querier in the network.
      
      The fix will only break out of the loop when there is a failure adding a
      multicast address.
      
      The mdb before the patch:
      
      dev ovirtmgmt port vnet0 grp ff02::1:ff7d:6603 temp
      dev ovirtmgmt port vnet1 grp ff02::1:ff7d:6604 temp
      dev ovirtmgmt port bond0.86 grp ff02::2 temp
      
      After the patch:
      
      dev ovirtmgmt port vnet0 grp ff02::1:ff7d:6603 temp
      dev ovirtmgmt port vnet1 grp ff02::1:ff7d:6604 temp

      cdc_ncm: Fix tx_bytes statistics · 44f6731d
      Bjørn Mork authored
      The tx_curr_frame_payload field is u32. When we try to calculate a
      small negative delta based on it, we end up with a positive integer
      close to 2^32 instead.  So the tx_bytes pointer increases by about
      2^32 for every transmitted frame.
      
      Fix by calculating the delta as a signed long.

      Netfilter fixes for net
      
      The following patchset contain Netfilter fixes for your net tree, they are:
      
      1) Fix a race in nfnetlink_log and nfnetlink_queue that can lead to a crash.
         This problem is due to wrong order in the per-net registration and netlink
         socket events. Patch from Francesco Ruggeri.
      
      2) Make sure that counters that userspace pass us are higher than 0 in all the
         x_tables frontends. Discovered via Trinity, patch from Dave Jones.
      
      3) Revert a patch for br_netfilter to rely on the conntrack status bits. This
         breaks stateless IPv6 NAT transformations. Patch from Florian Westphal.

      ipv4: Avoid crashing in ip_error · 381c759d
      Eric W. Biederman authored
      ip_error does not check if in_dev is NULL before dereferencing it.
      
      IThe following sequence of calls is possible:
      CPU A                          CPU B
      ip_rcv_finish
          ip_route_input_noref()
              ip_route_input_slow()
                                     inetdev_destroy()
          dst_input()
      
      With the result that a network device can be destroyed while processing
      an input packet.
      
      A crash was triggered with only unicast packets in flight, and
      forwarding enabled on the only network device.   The error condition
      was created by the removal of the network device.
      
      As such it is likely the that error code was -EHOSTUNREACH, and the
      action taken by ip_error (if in_dev had been accessible) would have
      been to not increment any counters and to have tried and likely failed
      to send an icmp error as the network device is going away.
      
      Therefore handle this weird case by just dropping the packet if
      !in_dev.  It will result in dropping the packet sooner, and will not
      result in an actual change of behavior.
      
      Fixes: 251da413 ("ipv4: Cache ip_error() routes even when not forwarding.")

      tcp: fix a potential deadlock in tcp_get_info() · d654976c
      Eric Dumazet authored
      Taking socket spinlock in tcp_get_info() can deadlock, as

      while packet processing can use the reverse locking order.

      Input: smtpe-ts - wait 50mS until polling for pen-up · 77b071e7
      Marek Vasut authored
      Wait a little bit longer, 50mS instead of 20mS, until the driver starts
      polling for pen-up. The problematic behavior before this patch is applied
      is as follows. The behavior was observed on the STMPE610QTR controller.
      
      Upon a physical pen-down event, the touchscreen reports one set of x-y-p
      coordinates and a pen-down event. After that, the pen-up polling is
      triggered and since the controller is not ready yet, the polling mistakenly
      detects a pen-up event while the physical state is still such that the pen
      is down on the touch surface.
      
      The pen-up handling flushes the controller FIFO, so after that, all the
      samples in the controller are discarded. The controller becomes ready
      shortly after this bogus pen-up handling and does generate again a pen-down
      interrupt. This time, the controller contains x-y-p samples which all read
      as zero. Since pressure value is zero, this set of samples is effectively
      ignored by userland.
      
      In the end, the driver just bounces between pen-down and bogus pen-up
      handling, generating no useful results. Fix this by giving the controller a
      bit more time before polling it for pen-up.

      Input: smtpe-ts - use msecs_to_jiffies() instead of HZ · e686e9e1
      Marek Vasut authored
      Use msecs_to_jiffies(20) instead of plain (HZ / 50), as the former is much
      more explicit about it's behavior. We want to schedule the task 20 mS from
      now, so make it explicit in the code.
