      net: phy: marvell: Enable interrupt function on LED2 pin · dd9a122a
      Esben Haabendal authored
      The LED2[2]/INTn pin on Marvell 88E1318S as well as 88E1510/12/14/18 needs
      to be configured to be usable as interrupt not only when WOL is enabled,
      but whenever we rely on interrupts from the PHY.

      net/sched: fix NULL dereference in the error path of tcf_bpf_init() · 3239534a
      Davide Caratti authored
      when tcf_bpf_init_from_ops() fails (e.g. because of program having invalid

      net/ipv6: Increment OUTxxx counters after netfilter hook · 71a1c915
      Jeff Barnhill authored
      At the end of ip6_forward(), IPSTATS_MIB_OUTFORWDATAGRAMS and
      IPSTATS_MIB_OUTOCTETS are incremented immediately before the NF_HOOK call
      for NFPROTO_IPV6 / NF_INET_FORWARD.  As a result, these counters get
      incremented regardless of whether or not the netfilter hook allows the
      packet to continue being processed.  This change increments the counters
      in ip6_forward_finish() so that it will not happen if the netfilter hook
      chooses to terminate the packet, which is similar to how IPv4 works.

      hv_netvsc: Ensure correct teardown message sequence order · a56d99d7
      Mohammed Gamal authored
      Prior to commit 0cf73780 ("hv_netvsc: netvsc_teardown_gpadl() split")
      the call sequence in netvsc_device_remove() was as follows (as
      implemented in netvsc_destroy_buf()):
      1- Send NVSP_MSG1_TYPE_REVOKE_RECV_BUF message
      2- Teardown receive buffer GPADL
      3- Send NVSP_MSG1_TYPE_REVOKE_SEND_BUF message
      4- Teardown send buffer GPADL
      5- Close vmbus
      
      This didn't work for WS2016 hosts. Commit 0cf73780
      ("hv_netvsc: netvsc_teardown_gpadl() split") rearranged the
      teardown sequence as follows:
      1- Send NVSP_MSG1_TYPE_REVOKE_RECV_BUF message
      2- Send NVSP_MSG1_TYPE_REVOKE_SEND_BUF message
      3- Close vmbus
      4- Teardown receive buffer GPADL
      5- Teardown send buffer GPADL
      
      That worked well for WS2016 hosts, but it prevented guests on older hosts from
      shutting down after changing network settings. Commit 0ef58b0a
      ("hv_netvsc: change GPAD teardown order on older versions") ensured the
      following message sequence for older hosts
      1- Send NVSP_MSG1_TYPE_REVOKE_RECV_BUF message
      2- Send NVSP_MSG1_TYPE_REVOKE_SEND_BUF message
      3- Teardown receive buffer GPADL
      4- Teardown send buffer GPADL
      5- Close vmbus
      
      However, with this sequence calling `ip link set eth0 mtu 1000` hangs and the
      process becomes uninterruptible. On futher analysis it turns out that on tearing
      down the receive buffer GPADL the kernel is waiting indefinitely
      in vmbus_teardown_gpadl() for a completion to be signaled.
      
      Here is a snippet of where this occurs:
      int vmbus_teardown_gpadl(struct vmbus_channel *channel, u32 gpadl_handle)
      {
              struct vmbus_channel_gpadl_teardown *msg;
              struct vmbus_channel_msginfo *info;
              unsigned long flags;
              int ret;
      
              info = kmalloc(sizeof(*info) +
                             sizeof(struct vmbus_channel_gpadl_teardown), GFP_KERNEL);
              if (!info)
                      return -ENOMEM;
      
              init_completion(&info->waitevent);
              info->waiting_channel = channel;
      [....]
              ret = vmbus_post_msg(msg, sizeof(struct vmbus_channel_gpadl_teardown),
                                   true);
      
              if (ret)
                      goto post_msg_err;
      
              wait_for_completion(&info->waitevent);
      [....]
      }
      
      The completion is signaled from vmbus_ongpadl_torndown(), which gets called when
      the corresponding message is received from the host, which apparently never happens
      in that case.
      This patch works around the issue by restoring the first mentioned message sequence
      for older hosts

      arp: fix arp_filter on l3slave devices · 58b35f27
      Miguel Fadon Perlines authored
      arp_filter performs an ip_route_output search for arp source address and
      checks if output device is the same where the arp request was received,
      if it is not, the arp request is not answered.
      
      This route lookup is always done on main route table so l3slave devices
      never find the proper route and arp is not answered.
      
      Passing l3mdev_master_ifindex_rcu(dev) return value as oif fixes the
      lookup for l3slave devices while maintaining same behavior for non
      l3slave devices as this function returns 0 in that case.

      We want to use dev_valid_name() to validate tunnel names,
      so better use strnlen(name, IFNAMSIZ) than strlen(name) to make
      sure to not upset KASAN.

        It is a lot, over 500 changes, but not huge by previous kernel release

        91k remvoed), thanks to finally being able to delete the IRDA drivers
        and networking code.
      
        We also deleted the ccree crypto driver, but that's coming back in
        through the crypto tree to you, in a much cleaned-up form.
      
        Added this round is at lot of "mt7621" device support, which is for an
        embedded device that Neil Brown cares about, and of course a handful
        of new IIO drivers as well.
      
        And finally, the fsl-mc core code moved out of the staging tree to the

       "This fixes some fallout from the net-next merge the other day, plus
        some non-merge-window-related bug fixes:
      
        1) Fix sparse warnings in bcmgenet, systemport, b53, and mt7530
           (Florian Fainelli)
      
        2) pptp does a bogus dst_release() on a route we have a single
           refcount on, and attached to a socket, which needs that refcount
           (Eric Dumazet)
      
        3) UDP connected sockets on ipv6 can race with route update handling,
           resulting in a pre-PMTU update route still stuck on the socket and
           thus continuing to get ICMPV6_PKT_TOOBIG errors. We end up never
           seeing the updated route. (Alexey Kodanev)
      
        4) Missing list initializer(s) in TIPC (Jon Maloy)
      
        5) Connect phy early to prevent crashes in lan78xx driver (Alexander
           Graf)
      
        6) Fix build with modular NVMEM (Arnd Bergmann)
      
        7) netdevsim canot mark nsim_devlink_net_ops and nsim_fib_net_ops as
           __net_initdata, as these are references from module unload
           unconditionally (Arnd Bergmann)"

       "This contains the new features we'd like to incorporate into the
        RISC-V port for 4.17. We might have a bit more stuff land later in the
        merge window, but I wanted to get this out earlier just so everyone
        can see where we currently stand.
      
        A short summary of the changes is:
      
         - We've added support for dynamic ftrace on RISC-V targets.
      
         - There have been a handful of cleanups to our atomic and locking
           routines. They now more closely match the released RISC-V memory
           model draft.
      
         - Our module loading support has been cleaned up and is now enabled
           by default, despite some limitations still existing.
      
         - A patch to define COMMANDLINE_FORCE instead of COMMANDLINE_OVERRIDE
           so the generic device tree code picks up handling all our command
           line stuff.
      
        There's more information in the merge commits for each patch set"

       "Nothing particularly stands out here, probably because people were
        tied up with spectre/meltdown stuff last time around. Still, the main
        pieces are:
      
         - Rework of our CPU features framework so that we can whitelist CPUs
           that don't require kpti even in a heterogeneous system
      
         - Support for the IDC/DIC architecture extensions, which allow us to
           elide instruction and data cache maintenance when writing out
           instructions
      
         - Removal of the large memory model which resulted in suboptimal
           codegen by the compiler and increased the use of literal pools,
           which could potentially be used as ROP gadgets since they are
           mapped as executable
      
         - Rework of forced signal delivery so that the siginfo_t is
           well-formed and handling of show_unhandled_signals is consolidated
           and made consistent between different fault types
      
         - More siginfo cleanup based on the initial patches from Eric
           Biederman
      
         - Workaround for Cortex-A55 erratum #1024718

       "A small set of updates for timers and timekeeping:
      
         - The most interesting change is the consolidation of clock MONOTONIC
           and clock BOOTTIME.
      
           Clock MONOTONIC behaves now exactly like clock BOOTTIME and does
           not longer ignore the time spent in suspend. A new clock
           MONOTONIC_ACTIVE is provived which behaves like clock MONOTONIC in
           kernels before this change. This allows applications to
           programmatically check for the clock MONOTONIC behaviour.
      
           As discussed in the review thread, this has the potential of
           breaking user space and we might have to revert this. Knock on wood
           that we can avoid that exercise.
