      net: Fix remcsum in GRO path to not change packet · 26c4f7da
      Tom Herbert authored
      Remote checksum offload processing is currently the same for both
      the GRO and non-GRO path. When the remote checksum offload option
      is encountered, the checksum field referred to is modified in
      the packet. So in the GRO case, the packet is modified in the
      GRO path and then the operation is skipped when the packet goes
      through the normal path based on skb->remcsum_offload. There is
      a problem in that the packet may be modified in the GRO path, but
      then forwarded off host still containing the remote checksum option.
      A remote host will again perform RCO but now the checksum verification
      will fail since GRO RCO already modified the checksum.
      
      To fix this, we ensure that GRO restores a packet to it's original
      state before returning. In this model, when GRO processes a remote
      checksum option it still changes the checksum per the algorithm
      but on return from lower layer processing the checksum is restored
      to its original value.
      
      In this patch we add define gro_remcsum structure which is passed
      to skb_gro_remcsum_process to save offset and delta for the checksum
      being changed. After lower layer processing, skb_gro_remcsum_cleanup
      is called to restore the checksum before returning from GRO.

      openvswitch: Add missing initialization in validate_and_copy_set_tun() · 13101602
      Geert Uytterhoeven authored
      net/openvswitch/flow_netlink.c: In function ‘validate_and_copy_set_tun’:
      net/openvswitch/flow_netlink.c:1749: warning: ‘err’ may be used uninitialized in this function
      
      If ipv4_tun_from_nlattr() returns a different positive value than
      OVS_TUNNEL_KEY_ATTR_GENEVE_OPTS, err will be uninitialized, and
      validate_and_copy_set_tun() may return an undefined value instead of a
      zero success indicator. Initialize err to zero to fix this.

      rds: rds_cong_queue_updates needs to defer the congestion update transmission · 80ad0d4a
      Sowmini Varadhan authored
      When the RDS transport is TCP, we cannot inline the call to rds_send_xmit
      from rds_cong_queue_update because
      (a) we are already holding the sock_lock in the recv path, and
          will deadlock when tcp_setsockopt/tcp_sendmsg try to get the sock
          lock
      (b) cong_queue_update does an irqsave on the rds_cong_lock, and this
          will trigger warnings (for a good reason) from functions called
          out of sock_lock.
      
      This patch reverts the change introduced by
      2fa57129 ("RDS: Bypass workqueue when queueing cong updates").
      
      The patch has been verified for both RDS/TCP as well as RDS/RDMA
      to ensure that there are not regressions for either transport:
       - for verification of  RDS/TCP a client-server unit-test was used,
         with the server blocked in gdb and thus unable to drain its rcvbuf,
         eventually triggering a RDS congestion update.
       - for RDS/RDMA, the standard IB regression tests were used

      xilinx usb2 gadget: get rid of incredibly annoying compile warning · 7796c11c
      Linus Torvalds authored
      This one was driving me mad, with several lines of warnings during the
      allmodconfig build for a single bogus pointer cast.  The warning was so
      verbose due to the indirect macro expansion explanation, and the whole
      thing was just for a debug printout.
      
      The bogus pointer-to-integer cast was pointless anyway, so just remove
      it, and use '%p' to show the pointer.

      The firmware version is a single byte so have the variable type agree.
      Since the address to this member is passed to the read function, using
      an int is not even portable.

      ALSA: line6: Add delay before reading status · e64e94df
      Chris Rorvick authored
      The device indicates the result of a read/write operation by making the
      status available on a subsequent request from the driver.  This is not
      ready immediately, though, so the driver is currently slamming the
      device with hundreds of pointless requests before getting the expected
      response.  Add a two millisecond delay before each attempt.  This is
      approximately the behavior observed with version 4.2.7.1 of the Windows
      driver.

      The BDW audio firmware DSP manages the DMA and the DMA cannot be
      stopped exactly at the end of the playback stream. This means
      stale samples may be played at PCM stop unless the driver copies

      crypto: fix af_alg_make_sg() conversion to iov_iter · 9399f0c5
      Linus Torvalds authored
      Commit 1d10eb2f ("crypto: switch af_alg_make_sg() to iov_iter")
      broke af_alg_make_sg() and skcipher_recvmsg() in the process of moving
      them to the iov_iter interfaces.  The 'npages' calculation in the formar
      calculated the number of *bytes* in the pages, and in the latter case
      the conversion didn't re-read the value of 'ctx->used' after waiting for
      it to become non-zero.
      
      This reverts to the original code for both these cases.

      Pull live patching infrastructure from Jiri Kosina:
       "Let me provide a bit of history first, before describing what is in
        this pile.
      
        Originally, there was kSplice as a standalone project that implemented
        stop_machine()-based patching for the linux kernel.  This project got
        later acquired, and the current owner is providing live patching as a
        proprietary service, without any intentions to have their
        implementation merged.
      
        Then, due to rising user/customer demand, both Red Hat and SUSE
        started working on their own implementation (not knowing about each
        other), and announced first versions roughly at the same time [1] [2].
      
        The principle difference between the two solutions is how they are
        making sure that the patching is performed in a consistent way when it
        comes to different execution threads with respect to the semantic
        nature of the change that is being introduced.
      
        In a nutshell, kPatch is issuing stop_machine(), then looking at
        stacks of all existing processess, and if it decides that the system
        is in a state that can be patched safely, it proceeds insterting code
        redirection machinery to the patched functions.
      
        On the other hand, kGraft provides a per-thread consistency during one
        single pass of a process through the kernel and performs a lazy
        contignuous migration of threads from "unpatched" universe to the
        "patched" one at safe checkpoints.
      
        If interested in a more detailed discussion about the consistency
        models and its possible combinations, please see the thread that
        evolved around [3].
      
        It pretty quickly became obvious to the interested parties that it's
        absolutely impractical in this case to have several isolated solutions
        for one task to co-exist in the kernel.  During a dedicated Live
        Kernel Patching track at LPC in Dusseldorf, all the interested parties
        sat together and came up with a joint aproach that would work for both
        distro vendors.  Steven Rostedt took notes [4] from this meeting.
      
        And the foundation for that aproach is what's present in this pull
        request.
      
        It provides a basic infrastructure for function "live patching" (i.e.
        code redirection), including API for kernel modules containing the
        actual patches, and API/ABI for userspace to be able to operate on the
        patches (look up what patches are applied, enable/disable them, etc).
      
        It's relatively simple and minimalistic, as it's making use of
        existing kernel infrastructure (namely ftrace) as much as possible.
        It's also self-contained, in a sense that it doesn't hook itself in
        any other kernel subsystem (it doesn't even touch any other code).
        It's now implemented for x86 only as a reference architecture, but
        support for powerpc, s390 and arm is already in the works (adding
        arch-specific support basically boils down to teaching ftrace about
        regs-saving).
      
        Once this common infrastructure gets merged, both Red Hat and SUSE
        have agreed to immediately start porting their current solutions on
        top of this, abandoning their out-of-tree code.  The plan basically is
        that each patch will be marked by flag(s) that would indicate which
        consistency model it is willing to use (again, the details have been
        sketched out already in the thread at [3]).
      
        Before this happens, the current codebase can be used to patch a large
        group of secruity/stability problems the patches for which are not too
        complex (in a sense that they don't introduce non-trivial change of
        function's return value semantics, they don't change layout of data
        structures, etc) -- this corresponds to LEAVE_FUNCTION &&
        SWITCH_FUNCTION semantics described at [3].

      sata_dwc_460ex: disable COMPILE_TEST again · 06cc01a0
      Linus Torvalds authored
      Commit 84683a7e ("sata_dwc_460ex: enable COMPILE_TEST for the
      driver") enabled this driver for non-ppc460-ex platforms, but it was
      then disabled for ARM and ARM64 by commit 2de5a9c0 ("sata_dwc_460ex:
      disable compilation on ARM and ARM64") because it's too noisy and
      broken.
      
      This disabled is entirely, because it's too noisy on x86-64 too, and
      there's no point in disabling architectures one by one.  At a minimum,
      the code isn't 64-bit clean, and even on 32-bit it is questionable
      whether it makes sense.

       "Bite-sized chunks this time, to avoid the MTA ratelimiting woes.
      
         - fs/notify updates
      
         - ocfs2
      
         - some of MM"
      
      That laconic "some MM" is mainly the removal of remap_file_pages(),
      which is a big simplification of the VM, and which gets rid of a *lot*
      of random cruft and special cases because we no longer support the
      non-linear mappings that it used.
      
      From a user interface perspective, nothing has changed, because the
      remap_file_pages() syscall still exists, it's just done by emulating the
      old behavior by creating a lot of individual small mappings instead of
      one non-linear one.
      
      The emulation is slower than the old "native" non-linear mappings, but
      nobody really uses or cares about remap_file_pages(), and simplifying
      the VM is a big advantage.

      Pull ACPI and power management updates from Rafael Wysocki:
       "We have a few new features this time, including a new SFI-based
        cpufreq driver, a new devfreq driver for Tegra Activity Monitor, a new
        devfreq class for providing its governors with raw utilization data
        and a new ACPI driver for AMD SoCs.
      
        Still, the majority of changes here are reworks of existing code to
        make it more straightforward or to prepare it for implementing new
        features on top of it.  The primary example is the rework of ACPI
        resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with
        support for IOAPIC hotplug implemented on top of it, but there is
        quite a number of changes of this kind in the cpufreq core, ACPICA,
        ACPI EC driver, ACPI processor driver and the generic power domains
        core code too.
      
        The most active developer is Viresh Kumar with his cpufreq changes.
      
        Specifics:
      
         - Rework of the core ACPI resources parsing code to fix issues in it
           and make using resource offsets more convenient and consolidation
           of some resource-handing code in a couple of places that have grown
           analagous data structures and code to cover the the same gap in the
           core (Jiang Liu, Thomas Gleixner, Lv Zheng).
      
         - ACPI-based IOAPIC hotplug support on top of the resources handling
           rework (Jiang Liu, Yinghai Lu).
      
         - ACPICA update to upstream release 20150204 including an interrupt
           handling rework that allows drivers to install raw handlers for
           ACPI GPEs which then become entirely responsible for the given GPE
           and the ACPICA core code won't touch it (Lv Zheng, David E Box,
           Octavian Purdila).
      
         - ACPI EC driver rework to fix several concurrency issues and other
           problems related to events handling on top of the ACPICA's new
           support for raw GPE handlers (Lv Zheng).
      
         - New ACPI driver for AMD SoCs analogous to the LPSS (Low-Power
           Subsystem) driver for Intel chips (Ken Xue).
