      ip6gre_xmit2() incorrectly sets transport header to inner payload

      Set transport header to gre header.
      (In ipip case the transport header is the inner ip header, so that's
      correct.)
      
      Found by inspection. In practice the incorrect transport header
      doesn't matter because the skb usually is sent to another net_device

      net/vxlan: Use the underlying device index when joining/leaving multicast groups · af9b078e
      Yan Burman authored
      The socket calls from vxlan to join/leave multicast group aren't
      using the index of the underlying device, as a result the stack uses
      the first interface that is up. This results in vxlan being non functional
      over a device which isn't the 1st to be up.
      Fix this by providing the iflink field to the vxlan instance
      to the multicast calls.

      tcp: should drop incoming frames without ACK flag set · c3ae62af
      Eric Dumazet authored
      In commit 96e0bf4b (tcp: Discard segments that ack data not yet
      sent) John Dykstra enforced a check against ack sequences.
      
      In commit 354e4aa3 (tcp: RFC 5961 5.2 Blind Data Injection Attack
      Mitigation) I added more safety tests.
      
      But we missed fact that these tests are not performed if ACK bit is
      not set.
      
      RFC 793 3.9 mandates TCP should drop a frame without ACK flag set.
      
      " fifth check the ACK field,
            if the ACK bit is off drop the segment and return"
      
      Not doing so permits an attacker to only guess an acceptable sequence
      number, evading stronger checks.
      
      Many thanks to Zhiyun Qian for bringing this issue to our attention.

      mm: Fix PageHead when !CONFIG_PAGEFLAGS_EXTENDED · ad4b3fb7
      Christoffer Dall authored
      Unfortunately with !CONFIG_PAGEFLAGS_EXTENDED, (!PageHead) is false, and
      (PageHead) is true, for tail pages.  If this is indeed the intended
      behavior, which I doubt because it breaks cache cleaning on some ARM
      systems, then the nomenclature is highly problematic.
      
      This patch makes sure PageHead is only true for head pages and PageTail
      is only true for tail pages, and neither is true for non-compound pages.
      
      [ This buglet seems ancient - seems to have been introduced back in Apr
        2008 in commit 6a1e7f77: "pageflags: convert to the use of new
        macros".  And the reason nobody noticed is because the PageHead()
        tests are almost all about just sanity-checking, and only used on
        pages that are actual page heads.  The fact that the old code returned
        true for tail pages too was thus not really noticeable.   - Linus ]

      cpts: fix build error by removing useless code. · cbc44dbe
      Richard Cochran authored
      The cpts driver tries to obtain the input clock frequency by calling the
      clock's internal 'recalc' method. Since <plat/clock.h> has been removed,
      this code can no longer compile.
      
      However, the driver never makes use of the frequency value, so this patch
      fixes the issue by removing the offending code altogether.

      batman-adv: fix random jitter calculation · 143cdd8f
      Akinobu Mita authored
      batadv_iv_ogm_emit_send_time() attempts to calculates a random integer
      in the range of 'orig_interval +- BATADV_JITTER' by the below lines.
      
              msecs = atomic_read(&bat_priv->orig_interval) - BATADV_JITTER;
              msecs += (random32() % 2 * BATADV_JITTER);
      
      But it actually gets 'orig_interval' or 'orig_interval - BATADV_JITTER'
      because '%' and '*' have same precedence and associativity is
      left-to-right.
      
      This adds the parentheses at the appropriate position so that it matches
      original intension.

      e_id is a backwards compatibility field only used for file systems
      that haven't been converted to use kuids and kgids.  When the posix
      acl tag field is neither ACL_USER nor ACL_GROUP assigning e_id is

      pidns: Stop pid allocation when init dies · c876ad76
      Eric W. Biederman authored
      Oleg pointed out that in a pid namespace the sequence.
      - pid 1 becomes a zombie
      - setns(thepidns), fork,...
      - reaping pid 1.
      - The injected processes exiting.
      
      Can lead to processes attempting access their child reaper and
      instead following a stale pointer.
      
      That waitpid for init can return before all of the processes in
      the pid namespace have exited is also unfortunate.
      
      Avoid these problems by disabling the allocation of new pids in a pid
      namespace when init dies, instead of when the last process in a pid
      namespace is reaped.

      CONFIG_HOTPLUG removal from networking core · 8baf82b3
      Greg KH authored
      CONFIG_HOTPLUG is always enabled now, so remove the unused code that was
      trying to be compiled out when this option was disabled, in the
      networking core.

      hwmon: (lm73} Detect and report i2c bus errors · 0602934f
      Chris Verges authored
      If an LM73 device does not exist on an I2C bus, attempts to communicate
      with the device result in an error code returned from the i2c read/write
      functions.  The current lm73 driver casts that return value from a s32
      type to a s16 type, then converts it to a temperature in celsius.
      Because negative temperatures are valid, it is difficult to distinguish
      between an error code printed to the response buffer and a negative
      temperature recorded by the sensor.
      
      The solution is to evaluate the return value from the i2c functions
      before performing any temperature calculations.  If the i2c function did
      not succeed, the error code should be passed back through the virtual
      file system layer instead of being printed into the response buffer.
      
      Before:
      
         $ cat /sys/class/hwmon/hwmon0/device/temp1_input
         -46
      
      After:
      
         $ cat /sys/class/hwmon/hwmon0/device/temp1_input
         cat: read error: No such device or address

      This reverts commit 79f77bf9.
      
      This is obviously wrong, and I have no idea how I missed seeing the
      warning in testing: I must just not have looked at the right logs.  The
      caller bumps rq_resused/rq_next_page, so it will always be hit on a
      large enough read.
