      ====================
      Intel Wired LAN Driver Fixes 2017-11-21
      
      This series contains fixes for igb/vf, ixgbe/vf, i40e/vf and fm10k.
      
      Jake fixes a regression issue with older firmware, where we were using
      the NVM lock to synchronize NVM reads for all devices and firmware
      versions, yet this caused issues with older firmware prior to version
      1.5.  Fixed this by only grabbing the lock for newer devices and firmware
      version 1.5 or newer.
      
      Zijie Pan fixes the calculation of the i40e VF MAC addresses, where it was
      possible to increment to the next MAC entry without calling
      i40e_add_mac_filter().
      
      Amritha removes the upper limit of 64 queues on a channel VSI since the
      upper bound is determined by the VSI's num_queue_pairs.
      
      Filip fixes an issue during FLR resets, where should have been checking
      for upcoming core reset and if so, just return with I40E_ERR_NOT_READY.
      
      Alan fixes the notifying clients of l2 parameters by copying the
      parameters to the client instance struct and re-organizes the priority
      in which the client tasks fire so that if the flag for notifying l2
      params is set, it will trigger before the client open task.  Also fixed
      the promiscuous settings after reset for all the VSI's.
      
      Brian King from IBM fixes an issue seen on Power systems which would
      result in skb list corruption and eventual kernel oops.  Brian
      provides the same fix for nearly all our drivers, to replace the
      read_barrier_depends with smp_rmb() to ensure loads are ordered with
      respect to the load of tx_buffer->next_to_watch.

      ====================
      pull-request: bpf 2017-11-23
      
      The following pull-request contains BPF updates for your *net* tree.
      
      The main changes are:
      
      1) Several BPF offloading fixes, from Jakub. Among others:
      
          - Limit offload to cls_bpf and XDP program types only.
          - Move device validation into the driver and don't make
            any assumptions about the device in the classifier due
            to shared blocks semantics.
          - Don't pass offloaded XDP program into the driver when
            it should be run in native XDP instead. Offloaded ones
            are not JITed for the host in such cases.
          - Don't destroy device offload state when moved to
            another namespace.
          - Revert dumping offload info into user space for now,
            since ifindex alone is not sufficient. This will be
            redone properly for bpf-next tree.
      
      2) Fix test_verifier to avoid using bpf_probe_write_user()
         helper in test cases, since it's dumping a warning into
         kernel log which may confuse users when only running tests.
         Switch to use bpf_trace_printk() instead, from Yonghong.
      
      3) Several fixes for correcting ARG_CONST_SIZE_OR_ZERO semantics
         before it becomes uabi, from Gianluca. More specifically:
      
          - Add a type ARG_PTR_TO_MEM_OR_NULL that is used only
            by bpf_csum_diff(), where the argument is either a
            valid pointer or NULL. The subsequent ARG_CONST_SIZE_OR_ZERO
            then enforces a valid pointer in case of non-0 size
            or a valid pointer or NULL in case of size 0. Given
            that, the semantics for ARG_PTR_TO_MEM in combination
            with ARG_CONST_SIZE_OR_ZERO are now such that in case
            of size 0, the pointer must always be valid and cannot
            be NULL. This fix in semantics allows for bpf_probe_read()
            to drop the recently added size == 0 check in the helper
            that would become part of uabi otherwise once released.
            At the same time we can then fix bpf_probe_read_str() and
            bpf_perf_event_output() to use ARG_CONST_SIZE_OR_ZERO
            instead of ARG_CONST_SIZE in order to fix recently
            reported issues by Arnaldo et al, where LLVM optimizes
            two boundary checks into a single one for unknown
            variables where the verifier looses track of the variable
            bounds and thus rejects valid programs otherwise.
      
      4) A fix for the verifier for the case when it detects
         comparison of two constants where the branch is guaranteed
         to not be taken at runtime. Verifier will rightfully prune
         the exploration of such paths, but we still pass the program
         to JITs, where they would complain about using reserved
         fields, etc. Track such dead instructions and sanitize
         them with mov r0,r0. Rejection is not possible since LLVM
         may generate them for valid C code and doesn't do as much
         data flow analysis as verifier. For bpf-next we might
         implement removal of such dead code and adjust branches
         instead. Fix from Alexei.

      net: accept UFO datagrams from tuntap and packet · 0c19f846
      Willem de Bruijn authored
      Tuntap and similar devices can inject GSO packets. Accept type
      VIRTIO_NET_HDR_GSO_UDP, even though not generating UFO natively.
      
      Processes are expected to use feature negotiation such as TUNSETOFFLOAD
      to detect supported offload types and refrain from injecting other
      packets. This process breaks down with live migration: guest kernels
      do not renegotiate flags, so destination hosts need to expose all
      features that the source host does.
      
      Partially revert the UFO removal from 182e0b6b~1..d9d30adf.
      This patch introduces nearly(*) no new code to simplify verification.
      It brings back verbatim tuntap UFO negotiation, VIRTIO_NET_HDR_GSO_UDP
      insertion and software UFO segmentation.
      
      It does not reinstate protocol stack support, hardware offload
      (NETIF_F_UFO), SKB_GSO_UDP tunneling in SKB_GSO_SOFTWARE or reception
      of VIRTIO_NET_HDR_GSO_UDP packets in tuntap.
      
      To support SKB_GSO_UDP reappearing in the stack, also reinstate
      logic in act_csum and openvswitch. Achieve equivalence with v4.13 HEAD
      by squashing in commit 93991221 ("net: skb_needs_check() removes
      CHECKSUM_UNNECESSARY check for tx.") and reverting commit 8d63bee6
      ("net: avoid skb_warn_bad_offload false positives on UFO").
      
      (*) To avoid having to bring back skb_shinfo(skb)->ip6_frag_id,
      ipv6_proxy_select_ident is changed to return a __be32 and this is
      assigned directly to the frag_hdr. Also, SKB_GSO_UDP is inserted
      at the end of the enum to minimize code churn.
      
      Tested
        Booted a v4.13 guest kernel with QEMU. On a host kernel before this
        patch `ethtool -k eth0` shows UFO disabled. After the patch, it is
        enabled, same as on a v4.13 host kernel.
      
        A UFO packet sent from the guest appears on the tap device:
          host:
            nc -l -p -u 8000 &
            tcpdump -n -i tap0
      
          guest:
            dd if=/dev/zero of=payload.txt bs=1 count=2000
            nc -u 192.16.1.1 8000 < payload.txt
      
        Direct tap to tap transmission of VIRTIO_NET_HDR_GSO_UDP succeeds,
        packets arriving fragmented:
      
          ./with_tap_pair.sh ./tap_send_ufo tap0 tap1
          (from https://github.com/wdebruij/kerneltools/tree/master/tests)

      net: realtek: r8169: implement set_link_ksettings() · 9e77d7a5
      Tobias Jakobi authored
      Commit 6fa1ba61 partially
      implemented the new ethtool API, by replacing get_settings()
      with get_link_ksettings(). This breaks ethtool, since the
      userspace tool (according to the new API specs) never tries
      the legacy set() call, when the new get() call succeeds.
      
      All attempts to chance some setting from userspace result in:
      > Cannot set new settings: Operation not supported
      
      Implement the missing set() call.

      net: ipv6: Fixup device for anycast routes during copy · 98d11291
      David Ahern authored
      Florian reported a breakage with anycast routes due to commit
      4832c30d ("net: ipv6: put host and anycast routes on device with
      address"). Prior to this commit anycast routes were added against the
      loopback device causing repetitive route entries with no insight into
      why they existed. e.g.:
        $ ip -6 ro ls  table local type anycast
        anycast 2001:db8:1:: dev lo proto kernel metric 0 pref medium
        anycast 2001:db8:2:: dev lo proto kernel metric 0 pref medium
        anycast fe80:: dev lo proto kernel metric 0 pref medium
        anycast fe80:: dev lo proto kernel metric 0 pref medium
      
      The point of commit 4832c30d is to add the routes using the device
      with the address which is causing the route to be added. e.g.,:
        $ ip -6 ro ls  table local type anycast
        anycast 2001:db8:1:: dev eth1 proto kernel metric 0 pref medium
        anycast 2001:db8:2:: dev eth2 proto kernel metric 0 pref medium
        anycast fe80:: dev eth2 proto kernel metric 0 pref medium
        anycast fe80:: dev eth1 proto kernel metric 0 pref medium
      
      For traffic to work as it did before, the dst device needs to be switched
      to the loopback when the copy is created similar to local routes.

      net/smc: Fix preinitialization of buf_desc in __smc_buf_create() · 68870370
      Geert Uytterhoeven authored
      With gcc-4.1.2:
      
          net/smc/smc_core.c: In function ‘__smc_buf_create’:
          net/smc/smc_core.c:567: warning: ‘bufsize’ may be used uninitialized in this function
      
      Indeed, if the for-loop is never executed, bufsize is used
      uninitialized.  In addition, buf_desc is stored for later use, while it
      is still a NULL pointer.
      
      Before, error handling was done by checking if buf_desc is non-NULL.
      The cleanup changed this to an error check, but forgot to update the
      preinitialization of buf_desc to an error pointer.
      
      Update the preinitializatin of buf_desc to fix this.

      ipv6: Do not consider linkdown nexthops during multipath · bbfcd776
      Ido Schimmel authored
      When the 'ignore_routes_with_linkdown' sysctl is set, we should not
      consider linkdown nexthops during route lookup.
      
      While the code correctly verifies that the initially selected route
      ('match') has a carrier, it does not perform the same check in the
      subsequent multipath selection, resulting in a potential packet loss.
      
      In case the chosen route does not have a carrier and the sysctl is set,
      choose the initially selected route.

      bpf: fix branch pruning logic · c131187d
      Alexei Starovoitov authored
      when the verifier detects that register contains a runtime constant
      and it's compared with another constant it will prune exploration
      of the branch that is guaranteed not to be taken at runtime.
      This is all correct, but malicious program may be constructed
      in such a way that it always has a constant comparison and
      the other branch is never taken under any conditions.
      In this case such path through the program will not be explored
      by the verifier. It won't be taken at run-time either, but since
      all instructions are JITed the malicious program may cause JITs
      to complain about using reserved fields, etc.
      To fix the issue we have to track the instructions explored by
      the verifier and sanitize instructions that are dead at run time
      with NOPs. We cannot reject such dead code, since llvm generates
      it for valid C code, since it doesn't do as much data flow
      analysis as the verifier does.

      bpf: change bpf_probe_write_user to bpf_trace_printk in test_verifier · f1a8b8e3
      Yonghong Song authored
      There are four tests in test_verifier using bpf_probe_write_user
      helper. These four tests will emit the following kernel messages
        [   12.974753] test_verifier[220] is installing a program with bpf_probe_write_user

        ......
      
      This may confuse certain users. This patch replaces bpf_probe_write_user
      with bpf_trace_printk. The test_verifier already uses bpf_trace_printk
      earlier in the test and a trace_printk warning message has been printed.
      So this patch does not emit any more kernel messages.

      ====================
      A few things:
       * straggler timer conversions from Kees
       * memory leak fix in hwsim
       * fix some fallout from regdb changes if wireless is built-in
       * also free aggregation sessions in startup state when station
         goes away, to avoid crashing the timer

      tipc: fix access of released memory · e0e853ac
      Jon Maloy authored
      When the function tipc_group_filter_msg() finds that a member event
      indicates that the member is leaving the group, it first deletes the
      member instance, and then purges the message queue being handled
      by the call. But the message queue is an aggregated field in the
      just deleted item, leading the purge call to access freed memory.
      
      We fix this by swapping the order of the two actions.
