      Input: synaptics-rmi4 - register F03 port as pass-through serio · a0897d5f
      Dmitry Torokhov authored
      
      
      The 5th generation Thinkpad X1 Carbons use Synaptics touchpads accessible
      over SMBus/RMI, combined with ALPS or Elantech trackpoint devices instead
      of classic IBM/Lenovo trackpoints. Unfortunately there is no way for ALPS
      driver to detect whether it is dealing with touchpad + trackpoint
      combination or just a trackpoint, so we end up with a "phantom" dualpoint
      ALPS device in addition to real touchpad and trackpoint.
      
      Given that we do not have any special advanced handling for ALPS or
      Elantech trackpoints (unlike IBM trackpoints that have separate driver and
      a host of options) we are better off keeping the trackpoints in PS/2
      emulation mode. We achieve that by setting serio type to SERIO_PS_PSTHRU,
      which will limit number of protocols psmouse driver will try. In addition
      to getting rid of the "phantom" touchpads, this will also speed up probing
      of F03 pass-through port.

      Input: axp20x-pek - switch to acpi_dev_present and check for ACPI0011 too · 0fd5f221
      Hans de Goede authored
      
      
      acpi_dev_found checks that there is a matching ACPI node, but it
      may be disabled (_STA method returns 0) in which case the
      soc_button_array driver will not bind to it and axp20x-pek should
      handle the power-button.
      
      This commit switches from acpi_dev_found to acpi_dev_present to
      avoid not registering an input-dev for the powerbutton when there
      is a disabled PNP0C40 device.
      
      The ACPI-6.0 standard defines a standard gpio button device using
      the ACPI0011 HID replacing the custom PNP0C40 gpio device, many
      newer devices define both PNP0C40 and ACPI0011 devices enabling one
      or the other depending on whether the BIOS thinks it is going to boot
      Android or Windows.
      
      This commit adds a check for the ACPI0011 device, so that if
      either device is present *and* enabled we don't register an input-dev
      for the powerbutton.

      Input: axp20x-pek - only check for "INTCFD9" ACPI device on Cherry Trail · 8d4b3137
      Hans de Goede authored
      Commit 9b13a4ca ("Input: axp20x-pek - do not register input device
      on some systems") added a check for the INTCFD9 ACPI device which also
      handles the powerbutton as on some systems the powerbutton is connected
      to both the PMIC, handled by axp20x-pek, and to a gpio on the SoC, handled
      by soc_button_array which attaches itself to the INTCFD9 ACPI device.
      
      Testing + comparing DSDTs has shown that this only happens on Cherry
      Trail devices with an AXP288 PMIC, the AXP288 PMIC is also used on
      Bay Trail devices but there the power button is only connected to
      the PMIC and not handled by soc_button_array.
      
      This means that the INTCFD9 check has caused a regression on Bay Trail
      devices, causing power-button presses to no longer be seen.
      
      This commit fixes this by limiting the check to devices where the ACPI
      node for the AXP288 contains a _HRV (hardware revision) attribute with
      a value of 3 which indicates we are dealing with a Cherry Trail platform.

      Interrupts should not be enabled at this early in the boot process. It is
      also fine to leave interrupts enabled during this time as there's only one

      If early_boot_irqs_disabled is set, it is safe to run cpu_flush_range() with
      interrupts disabled. Don't trigger a BUG_ON() in that case.

      Masami Hiramatsu authored
      Add a testcase to test kprobes via ftrace interface
      with many concurrent kprobe events.
      
      This tries to add many kprobe events (up to 256) on
      kernel functions. To avoid making ftrace-based
      kprobes (kprobes on fentry), it skips first N bytes
      (on x86 N=5, on ppc or arm N=4) of function entry.
      After that, it enables all those events, disable it,
      and remove it.
      
      Since the unoptimization buffer reclaiming will
      be delayed, after removing events, it will wait
      enough time.

      ftrace: Fix memory leak in ftrace_graph_release() · f9797c2f
      Luis Henriques authored
      ftrace_hash is being kfree'ed in ftrace_graph_release(), however the
      ->buckets field is not.  This results in a memory leak that is easily
      captured by kmemleak:

      I could reproduce the issue with KASAN kernels, between
      10.246.7.151 and 10.246.7.152 :
      
      1) 20 concurrent netperf -t TCP_RR -H 10.246.7.152 -l 1000 &
      
      2) At the same time run following loop :
      while :
      do
       ip ro add 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
       ip ro del 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
      done
      
      Cong Wang attempted to add back rt->fi in commit
      82486aa6 ("ipv4: restore rt->fi for reference counting")
      but this proved to add some issues that were complex to solve.
      
      Instead, I suggested to add a refcount to the metrics themselves,
      being a standalone object (in particular, no reference to other objects)
      
      I tried to make this patch as small as possible to ease its backport,
      instead of being super clean. Note that we believe that only ipv4 dst
      need to take care of the metric refcount. But if this is wrong,
      this patch adds the basic infrastructure to extend this to other
      families.
      
      Many thanks to Julian Anastasov for reviewing this patch, and Cong Wang
      for his efforts on this problem.

      ip6_tunnel, ip6_gre: fix setting of DSCP on encapsulated packets · 0e9a7095
      Peter Dawson authored
      This fix addresses two problems in the way the DSCP field is formulated
       on the encapsulating header of IPv6 tunnels.
      Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195661
      
      1) The IPv6 tunneling code was manipulating the DSCP field of the
       encapsulating packet using the 32b flowlabel. Since the flowlabel is
       only the lower 20b it was incorrect to assume that the upper 12b
       containing the DSCP and ECN fields would remain intact when formulating
       the encapsulating header. This fix handles the 'inherit' and
       'fixed-value' DSCP cases explicitly using the extant dsfield u8 variable.
      
      2) The use of INET_ECN_encapsulate(0, dsfield) in ip6_tnl_xmit was
       incorrect and resulted in the DSCP value always being set to 0.
      
      Commit 90427ef5 ("ipv6: fix flow labels when the traffic class
       is non-0") caused the regression by masking out the flowlabel
       which exposed the incorrect handling of the DSCP portion of the
       flowlabel in ip6_tunnel and ip6_gre.
      
      Fixes: 90427ef5

      sctp: fix ICMP processing if skb is non-linear · 804ec7eb
      Davide Caratti authored
      
      
      sometimes ICMP replies to INIT chunks are ignored by the client, even if
      the encapsulated SCTP headers match an open socket. This happens when the
      ICMP packet is carried by a paged skb: use skb_header_pointer() to read
      packet contents beyond the SCTP header, so that chunk header and initiate
      tag are validated correctly.
      
      v2:
      - don't use skb_header_pointer() to read the transport header, since
        icmp_socket_deliver() already puts these 8 bytes in the linear area.
      - change commit message to make specific reference to INIT chunks.

      net: llc: add lock_sock in llc_ui_bind to avoid a race condition · 0908cf4d
      linzhang authored
      
      
      There is a race condition in llc_ui_bind if two or more processes/threads
      try to bind a same socket.
      
      If more processes/threads bind a same socket success that will lead to
      two problems, one is this action is not what we expected, another is
      will lead to kernel in unstable status or oops(in my simple test case,
      cause llc2.ko can't unload).
      
      The current code is test SOCK_ZAPPED bit to avoid a process to
      bind a same socket twice but that is can't avoid more processes/threads
      try to bind a same socket at the same time.
      
      So, add lock_sock in llc_ui_bind like others, such as llc_ui_connect.
