       "Here are some late but important fixes for the v4.6 kernel series.
        ACPI and RCAR, so two driver fixes (PM related) and a self-evident
        string lookup fix for ACPI GPIOs:
      
         - A serious ACPI fix targeted for stable: lookup strings were being
           free'd.
      
         - Revert two patches from the RCAR driver"

      gre: do not pull header in ICMP error processing · b7f8fe25
      Jiri Benc authored
      iptunnel_pull_header expects that IP header was already pulled; with this
      expectation, it pulls the tunnel header. This is not true in gre_err.
      Furthermore, ipv4_update_pmtu and ipv4_redirect expect that skb->data points
      to the IP header.
      
      We cannot pull the tunnel header in this path. It's just a matter of not
      calling iptunnel_pull_header - we don't need any of its effects.

      net: Implement net_dbg_ratelimited() for CONFIG_DYNAMIC_DEBUG case · 2c94b537
      Tim Bingham authored
      Prior to commit d92cff89 ("net_dbg_ratelimited: turn into no-op
      when !DEBUG") the implementation of net_dbg_ratelimited() was buggy
      for both the DEBUG and CONFIG_DYNAMIC_DEBUG cases.
      
      The bug was that net_ratelimit() was being called and, despite
      returning true, nothing was being printed to the console. This
      resulted in messages like the following -
      
      "net_ratelimit: %d callbacks suppressed"
      
      with no other output nearby.
      
      After commit d92cff89 ("net_dbg_ratelimited: turn into no-op when
      !DEBUG") the bug is fixed for the DEBUG case. However, there's no
      output at all for CONFIG_DYNAMIC_DEBUG case.
      
      This patch restores debug output (if enabled) for the
      CONFIG_DYNAMIC_DEBUG case.
      
      Add a definition of net_dbg_ratelimited() for the CONFIG_DYNAMIC_DEBUG
      case. The implementation takes care to check that dynamic debugging is
      enabled before calling net_ratelimit().
      
      Fixes: d92cff89 ("net_dbg_ratelimited: turn into no-op when !DEBUG")

      tipc: only process unicast on intended node · efe79050
      Hamish Martin authored
      We have observed complete lock up of broadcast-link transmission due to
      unacknowledged packets never being removed from the 'transmq' queue. This
      is traced to nodes having their ack field set beyond the sequence number
      of packets that have actually been transmitted to them.
      Consider an example where node 1 has sent 10 packets to node 2 on a
      link and node 3 has sent 20 packets to node 2 on another link. We
      see examples of an ack from node 2 destined for node 3 being treated as
      an ack from node 2 at node 1. This leads to the ack on the node 1 to node
      2 link being increased to 20 even though we have only sent 10 packets.
      When node 1 does get around to sending further packets, none of the
      packets with sequence numbers less than 21 are actually removed from the
      transmq.
      To resolve this we reinstate some code lost in commit d999297c ("tipc:
      reduce locking scope during packet reception") which ensures that only
      messages destined for the receiving node are processed by that node. This
      prevents the sequence numbers from getting out of sync and resolves the
      packet leakage, thereby resolving the broadcast-link transmission
      lock-ups we observed.
      
      While we are aware that this change only patches over a root problem that
      we still haven't identified, this is a sanity test that it is always
      legitimate to do. It will remain in the code even after we identify and
      fix the real problem.

      cxgb3: fix out of bounds read · 0b86a2a1
      Michal Schmidt authored
      An out of bounds read of 2 bytes was discovered in cxgb3 with KASAN.
      
      t3_config_rss() expects both arrays it gets as parameters to have
      terminators. setup_rss(), the caller, forgets to add a terminator to
      one of the arrays. Thankfully the iteration in t3_config_rss() stops
      anyway, but in the last iteration the check for the terminator
      is an out of bounds read.
      
      Add the missing terminator to rspq_map[].

      net/smscx5xx: use the device tree for mac address · c489565b
      Arnd Bergmann authored
      This takes the MAC address for smsc75xx/smsc95xx USB network devices
      from a the device tree. This is required to get a usable persistent
      address on the popular beagleboard, whose hardware designers
      accidentally forgot that an ethernet device really requires an a
      MAC address to be functional.
      
      The Raspberry Pi also ships smsc9514 without a serial EEPROM, stores
      the MAC address in ROM accessible via VC4 firmware.
      
      The smsc75xx and smsc95xx drivers are just two copies of the
      same code, so better fix both.

      gpiolib-acpi: Duplicate con_id string when adding it to the crs lookup list · 7df89e92
      Ville Syrjälä authored
      Calling gpiod_get() from a module and then unloading the module leads to an
      oops due to acpi_can_fallback_to_crs() storing the pointer to the passed
      'con_id' string onto acpi_crs_lookup_list. The next guy to come along will then
      try to access the string but the memory may now be gone with the module.
      Make a copy of the passed string instead, and store the copy on the list.

       "One revert of a recent cpufreq commit that introduced a regression and
        a fix for intel_pstate's Turbo Activation Ratio handling code.
      
        Specifics:
      
         - Revert cpufreq commit that attempted to fix a problem in the
           ondemand/conservative governor code, but did that incorrectly and
           introduced another problem instead (Rafael Wysocki).
      
         - Fix incorrect decoding of MSR contents related to the Turbo
           Activation Ratio (TAR) handling in the intel_pstate driver
           (Srinivas Pandruvada)"

       "Final set of -rc fixes for 4.6.
      
        I've collected up a number of patches that are all pretty small with
        the exception of only a couple.  The hfi1 driver has a number of
        important patches, and it is what really drives the line count of this
        pull request up.  These are all small and I've got this kernel built
        and running in the test lab (I have most of the hardware, I think nes
        is the only thing in this patch set that I can't say I've personally
        tested and have up and running).
      
        Summary:
      
         - A number of collected fixes for oopses, memory corruptions,
           deadlocks, etc.  All of these fixes are small (many only 5-10
           lines), obvious, and tested.
      
         - Fix for the security issue related to the use of write for
           bi-directional communications"
