      net: stmmac: dwmac-meson8b: ignore the second clock input · f87777a3
      Martin Blumenstingl authored
      The dwmac glue registers on Amlogic Meson8b and newer SoCs has two clock
      inputs:
      - Meson8b and Meson8m2: MPLL2 and MPLL2 (the same parent is wired to
        both inputs)
      - GXBB, GXL, GXM, AXG, G12A, G12B, SM1: FCLK_DIV2 and MPLL2
      
      All known vendor kernels and u-boots are using the first input only. We
      let the common clock framework automatically choose the "right" parent.
      For some boards this causes a problem though, specificially with G12A and
      newer SoCs. The clock input is used for generating the 125MHz RGMII TX
      clock. For the two input clocks this means on G12A:
      - FCLK_DIV2: 999999985Hz / 8 = 124999998.125Hz
      - MPLL2: 499999993Hz / 4 = 124999998.25Hz
      
      In theory MPLL2 is the "better" clock input because it's gets us 0.125Hz
      closer to the requested frequency than FCLK_DIV2. In reality however
      there is a resource conflict because MPLL2 is needed to generate some of
      the audio clocks. dwmac-meson8b probes first and sets up the clock tree
      with MPLL2. This works fine until the audio driver comes and "steals"
      the MPLL2 clocks and configures it with it's own rate (294909637Hz). The
      common clock framework happily changes the MPLL2 rate but does not
      reconfigure our RGMII TX clock tree, which then ends up at 73727409Hz,
      which is more than 40% off the requested 125MHz.
      
      Don't use the second clock input for now to force the common clock
      framework to always select the first parent. This mimics the behavior
      from the vendor driver and fixes the clock resource conflict with the
      audio driver on G12A boards. Once the common clock framework can handle
      this situation this change can be reverted again.

      Pull tracing updates from Steven Rostedt:
       "The major update to this release is that there's a new arch config
        option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS.
      
        Currently, only x86_64 enables it. All the ftrace callbacks now take a
        struct ftrace_regs instead of a struct pt_regs. If the architecture
        has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will
        have enough information to read the arguments of the function being
        traced, as well as access to the stack pointer.
      
        This way, if a user (like live kernel patching) only cares about the
        arguments, then it can avoid using the heavier weight "regs" callback,
        that puts in enough information in the struct ftrace_regs to simulate
        a breakpoint exception (needed for kprobes).
      
        A new config option that audits the timestamps of the ftrace ring
        buffer at most every event recorded.
      
        Ftrace recursion protection has been cleaned up to move the protection
        to the callback itself (this saves on an extra function call for those
        callbacks).
      
        Perf now handles its own RCU protection and does not depend on ftrace
        to do it for it (saving on that extra function call).
      
        New debug option to add "recursed_functions" file to tracefs that
        lists all the places that triggered the recursion protection of the
        function tracer. This will show where things need to be fixed as
        recursion slows down the function tracer.
      
        The eval enum mapping updates done at boot up are now offloaded to a
        work queue, as it caused a noticeable pause on slow embedded boards.

       "Summary of modules changes for the 5.11 merge window:
      
         - Fix a race condition between systemd/udev and the module loader.
      
           The module loader was sending a uevent before the module was fully
           initialized (i.e., before its init function has been called). This
           means udev can start processing the module uevent before the module
           has finished initializing, and some udev rules expect that the
           module has initialized already upon receiving the uevent.
      
           This resulted in some systemd mount units failing if udev processes
           the event faster than the module can finish init. This is fixed by
           delaying the uevent until after the module has called its init
           routine.
      
         - Make the linker array sections for kernel params and module version
           attributes more robust by switching to use the alignment of the
           type in question.
      
           Namely, linker section arrays will be constructed using the
           alignment required by the struct (using __alignof__()) as opposed
           to a specific value such as sizeof(void *) or sizeof(long). This is
           less likely to cause breakages should the size of the type ever
           change (Johan Hovold)
      
         - Fix module state inconsistency by setting it back to GOING when a
           module fails to load and is on its way out (Miroslav Benes)

       - Allow unprivileged mounting in a user namespace.
      
         For quite some time the security model of overlayfs has been that
         operations on underlying layers shall be performed with the
         privileges of the mounting task.
      
         This way an unprvileged user cannot gain privileges by the act of
         mounting an overlayfs instance. A full audit of all function calls
         made by the overlayfs code has been performed to see whether they
         conform to this model, and this branch contains some fixes in this
         regard.

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've made more work into per-file compression support.
      
        For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
        change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
        DECOMPRESS_FILE provides a way to compress and decompress the existing
        normal files manually.
      
        There is also a new mount option, compress_mode=fs|user, which can
        control who compresses the data.
      
        Chao also added a checksum feature with a mount option so that
        we are able to detect any corrupted cluster.
      
        In addition, Daniel contributed casefolding with encryption patch,
        which will be used for Android devices.
      
        Summary:
      
        Enhancements:
         - add ioctls and mount option to manage per-file compression feature
         - support casefolding with encryption
         - support checksum for compressed cluster
         - avoid IO starvation by replacing mutex with rwsem
         - add sysfs, max_io_bytes, to control max bio size
      
        Bug fixes:
         - fix use-after-free issue when compression and fsverity are enabled
         - fix consistency corruption during fault injection test
         - fix data offset for lseek
         - get rid of buffer_head which has 32bits limit in fiemap
         - fix some bugs in multi-partitions support

      nfp: move indirect block cleanup to flower app stop callback · 5b33afee
      Simon Horman authored
      The indirect block cleanup may cause control messages to be sent
      if offloaded flows are present. However, by the time the flower app
      cleanup callback is called txbufs are no longer available and attempts
      to send control messages result in a NULL-pointer dereference in
      nfp_ctrl_tx_one().
      
      This problem may be resolved by moving the indirect block cleanup
      to the stop callback, where txbufs are still available.
      
      As suggested by Jakub Kicinski and Louis Peens.

              if (!t) {
                      ret = -ENOMEM;
                      goto out;
              }
              t->hregion = ip_set_alloc(ahash_sizeof_regions(htable_bits));
      
      Increased htable_bits can force htable_size() to return 0.
      In own turn ip_set_alloc(0) returns not 0 but ZERO_SIZE_PTR,
      so follwoing access to t->hregion should trigger an OOPS.
