      can: peak_usb: fix missing ctrlmode_ init for every dev · b0d4724b
      Stephane Grosjean authored
      Fixes a missing initialization of ctrlmode and ctrlmode_supported fields,
      for all other CAN devices than the first one. This fix only concerns
      the PCAN-USB Pro FD dual-channels CAN-FD device made by PEAK-System.

      can: add missing initialisations in CAN related skbuffs · 96943901
      Oliver Hartkopp authored
      When accessing CAN network interfaces with AF_PACKET sockets e.g. by dhclient
      this can lead to a skb_under_panic due to missing skb initialisations.
      
      Add the missing initialisations at the CAN skbuff creation times on driver
      level (rx path) and in the network layer (tx path).

      ip: fix error queue empty skb handling · c247f053
      Willem de Bruijn authored
      When reading from the error queue, msg_name and msg_control are only
      populated for some errors. A new exception for empty timestamp skbs
      added a false positive on icmp errors without payload.
      
      `traceroute -M udpconn` only displayed gateways that return payload
      with the icmp error: the embedded network headers are pulled before
      sock_queue_err_skb, leaving an skb with skb->len == 0 otherwise.
      
      Fix this regression by refining when msg_name and msg_control
      branches are taken. The solutions for the two fields are independent.
      
      msg_name only makes sense for errors that configure serr->port and
      serr->addr_offset. Test the first instead of skb->len. This also fixes
      another issue. saddr could hold the wrong data, as serr->addr_offset
      is not initialized  in some code paths, pointing to the start of the
      network header. It is only valid when serr->port is set (non-zero).
      
      msg_control support differs between IPv4 and IPv6. IPv4 only honors
      requests for ICMP and timestamps with SOF_TIMESTAMPING_OPT_CMSG. The
      skb->len test can simply be removed, because skb->dev is also tested
      and never true for empty skbs. IPv6 honors requests for all errors
      aside from local errors and timestamps on empty skbs.
      
      In both cases, make the policy more explicit by moving this logic to
      a new function that decides whether to process msg_control and that
      optionally prepares the necessary fields in skb->cb[]. After this
      change, the IPv4 and IPv6 paths are more similar.
      
      The last case is rxrpc. Here, simply refine to only match timestamps.

      The problem here is that the enet hw clocks are not getting
      initialized because of a test to avoid the initialization if
      UEFI is used to boot. This is an incorrect test. When booting
      with UEFI and devicetree, the kernel must still initialize
      the enet hw clocks. If booting with ACPI, the clock hw is
      not exposed to the kernel and it is that case where we want
      to avoid initializing clocks.

      bnx2x: Force fundamental reset for EEH recovery · da293700
      Brian King authored
      EEH recovery for bnx2x based adapters is not reliable on all Power
      systems using the default hot reset, which can result in an
      unrecoverable EEH error. Forcing the use of fundamental reset
      during EEH recovery fixes this.

      David Vrabel authored
      When handling a from-guest frag list, xenvif_handle_frag_list()
      replaces the frags before calling the destructor to clean up the
      original (foreign) frags.  Whilst this is safe (the destructor doesn't
      actually use the frags), it looks odd.
      
      Reorder the function to be less confusing.

      xen-netback: unref frags when handling a from-guest skb with a frag list · 49d9991a
      David Vrabel authored
      Every time a VIF is destroyed up to 256 pages may be leaked if packets
      with more than MAX_SKB_FRAGS frags were transmitted from the guest.
      Even worse, if another user of ballooned pages allocated one of these
      ballooned pages it would not handle the unexpectedly >1 page count
      (e.g., gntdev would deadlock when unmapping a grant because the page
      count would never reach 1).
      
      When handling a from-guest skb with a frag list, unref the frags
      before releasing them so they are freed correctly when the VIF is
      destroyed.

      ARM: fix typos in smc91x platform data · 04b91701

      I recently did a rework of the smc91x driver and did some build-testing
      by compiling hundreds of randconfig kernels. Unfortunately, my script
      was wrong and did not actually test the configurations that mattered,
      so I introduced stupid typos in almost every file I touched.
      
      I fixed my script now, built all configurations that actually matter
      and fixed all the typos, this is the result.

      Currently the list is traversed using rcu variant. That is not correct

      When do suspend/resume stress test, some log shows "rcv is not +last".
      The issue is that enet suspend will disable phy clock, phy link down,
      after resume back, enet MAC redo initial and ready to tx/rx packet,
      but phy still is not ready which is doing auto-negotiation. When phy

      ====================
      drivers: net: xgene: Fix backward compatibility of newer firmware with older kernel
      
      Kernel 3.17 driver supports only RGMII ethernet interface.
      Since the Tianocore DT contains same compatibility string for RGMII,
      SGMII based 1G and XFI based 10G interfaces, crash happens when probe called
      on SGMII based 1G and XFI based 10G interface.
      
      This patch fixes the backward compatibility of the older driver with the
      newer firmware by making the binding unique so that the older driver won't
      recognize the non-supported interfaces.
      
      v2: Address comments from v1
      * updated cover letter subject line with net: xgene
      * Documentation: formatted compatible string values as list
      
      v1:
      * Initial version

      net: ping: Return EAFNOSUPPORT when appropriate. · 9145736d
      Lorenzo Colitti authored
      1. For an IPv4 ping socket, ping_check_bind_addr does not check
         the family of the socket address that's passed in. Instead,
         make it behave like inet_bind, which enforces either that the
         address family is AF_INET, or that the family is AF_UNSPEC and
         the address is 0.0.0.0.
      2. For an IPv6 ping socket, ping_check_bind_addr returns EINVAL
         if the socket family is not AF_INET6. Return EAFNOSUPPORT
         instead, for consistency with inet6_bind.
      3. Make ping_v4_sendmsg and ping_v6_sendmsg return EAFNOSUPPORT
         instead of EINVAL if an incorrect socket address structure is
         passed in.
      4. Make IPv6 ping sockets be IPv6-only. The code does not support
         IPv4, and it cannot easily be made to support IPv4 because
         the protocol numbers for ICMP and ICMPv6 are different. This
         makes connect(::ffff:192.0.2.1) fail with EAFNOSUPPORT instead
         of making the socket unusable.
      
      Among other things, this fixes an oops that can be triggered by:
      
          int s = socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP);
          struct sockaddr_in6 sin6 = {
              .sin6_family = AF_INET6,
              .sin6_addr = in6addr_any,
          };
          bind(s, (struct sockaddr *) &sin6, sizeof(sin6));

      bcm63xx_enet: fix poll callback. · cd33ccf5
      Nicolas Schichan authored
      In case there was some tx buffer reclaimed and not enough rx packets
      to consume the whole budget, napi_complete would not be called and
      interrupts would be kept disabled, effectively resulting in the
      network core never to call the poll callback again and no rx/tx
      interrupts to be fired either.
      
      Fix that by only accounting the rx work done in the poll callback.

      stmmac: check IRQ availability early on probe · 8f02d8da
      Alexey Brodkin authored
      Currently we're getting IRQs after lots of resources are already
      allocated:
       * netdev
       * clocks
       * MDIO bus
      Also HW gets initialized by the time when checking IRQs as well.
      
      Now there's a possibility for master interrupt controller to be not
      probed yet. This will lead to exit from GMAC probe routine with "-
      EPROBE_DEFER" and so deferred probe will hapen later on.
      
      But since we exited the first GMAC probe without release of all
      allocated resources there could be conflicts on subsequent probes.
      
      For example this is what happens for me:

      netfilter: nf_tables: fix error handling of rule replacement · 59900e0a
      Pablo Neira Ayuso authored
      In general, if a transaction object is added to the list successfully,
      we can rely on the abort path to undo what we've done. This allows us to
      simplify the error handling of the rule replacement path in
      nf_tables_newrule().
      
      This implicitly fixes an unnecessary removal of the old rule, which
      needs to be left in place if we fail to replace.

      Patrick McHardy authored
      The NFT_USERDATA_MAXLEN is defined to 256, however we only have a u8
      to store its size. Introduce a struct nft_userdata which contains a
      length field and indicate its presence using a single bit in the rule.
      
      The length field of struct nft_userdata is also a u8, however we don't
      store zero sized data, so the actual length is udata->len + 1.

      netfilter: nf_tables: fix transaction race condition · 8670c3a5
      Patrick McHardy authored
      A race condition exists in the rule transaction code for rules that
      get added and removed within the same transaction.
      
      The new rule starts out as inactive in the current and active in the
      next generation and is inserted into the ruleset. When it is deleted,
      it is additionally set to inactive in the next generation as well.
      
      On commit the next generation is begun, then the actions are finalized.
      For the new rule this would mean clearing out the inactive bit for
      the previously current, now next generation.
      
      However nft_rule_clear() clears out the bits for *both* generations,
      activating the rule in the current generation, where it should be
      deactivated due to being deleted. The rule will thus be active until
      the deletion is finalized, removing the rule from the ruleset.
      
      Similarly, when aborting a transaction for the same case, the undo
      of insertion will remove it from the RCU protected rule list, the
      deletion will clear out all bits. However until the next RCU
      synchronization after all operations have been undone, the rule is
      active on CPUs which can still see the rule on the list.
      
      Generally, there may never be any modifications of the current
      generations' inactive bit since this defeats the entire purpose of
      atomicity. Change nft_rule_clear() to only touch the next generations
      bit to fix this.

      powerpc/iommu: Remove IOMMU device references via bus notifier · 4ad04e59
      Nishanth Aravamudan authored
      After d905c5df ("PPC: POWERNV: move iommu_add_device earlier"), the
      refcnt on the kobject backing the IOMMU group for a PCI device is
      elevated by each call to pci_dma_dev_setup_pSeriesLP() (via
      set_iommu_table_base_and_group). When we go to dlpar a multi-function
      PCI device out:
      
              iommu_reconfig_notifier ->
                      iommu_free_table ->
                              iommu_group_put
                              BUG_ON(tbl->it_group)
      
      We trip this BUG_ON, because there are still references on the table, so
      it is not freed. Fix this by moving the powernv bus notifier to common
      code and calling it for both powernv and pseries.

      powerpc/smp: Wait until secondaries are active & online · 875ebe94
      Michael Ellerman authored
      Anton has a busy ppc64le KVM box where guests sometimes hit the infamous
      "kernel BUG at kernel/smpboot.c:134!" issue during boot:
      
        BUG_ON(td->cpu != smp_processor_id());
      
      Basically a per CPU hotplug thread scheduled on the wrong CPU. The oops
      output confirms it:
      
        CPU: 0
        Comm: watchdog/130
      
      The problem is that we aren't ensuring the CPU active bit is set for the
      secondary before allowing the master to continue on. The master unparks
      the secondary CPU's kthreads and the scheduler looks for a CPU to run
      on. It calls select_task_rq() and realises the suggested CPU is not in
      the cpus_allowed mask. It then ends up in select_fallback_rq(), and
      since the active bit isnt't set we choose some other CPU to run on.
      
      This seems to have been introduced by 6acbfb96 "sched: Fix hotplug
      vs. set_cpus_allowed_ptr()", which changed from setting active before
      online to setting active after online. However that was in turn fixing a
      bug where other code assumed an active CPU was also online, so we can't
      just revert that fix.
      
      The simplest fix is just to spin waiting for both active & online to be
      set. We already have a barrier prior to set_cpu_online() (which also
      sets active), to ensure all other setup is completed before online &
      active are set.

      Set actions consist of a regular OVS_KEY_ATTR_* attribute nested inside
      of a OVS_ACTION_ATTR_SET action attribute. When converting masked actions
      back to regular set actions, the inner attribute length was not changed,
      ie, double the length being serialized. This patch fixes the bug.
