      Pull clk updates from Stephen Boyd:
       "I'm actually surprised this time. There aren't any new Qualcomm SoC
        clk drivers. And there's zero diff in the core clk framework.
      
        Instead we have new clk drivers for STM and Sophgo, with
        Samsung^WGoogle in third for the diffstat because they introduced HSI0
        and HSI2 clk drivers for Google's GS101 SoC (high speed interface
        things like PCIe, UFS, and MMC).
      
        Beyond those big diffs there's the usual updates to various clk
        drivers for incorrect parent descriptions or mising
        MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
        interesting here.
      
        New Drivers:
         - STM32MP257 SoC clk driver
         - Airoha EN7581 SoC clk driver
         - Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
         - Loongson-2k0500 and Loongson-2k2000 SoC clk driver
         - Add HSI0 and HSI2 clock controllers for Google GS101
         - Add i.MX95 BLK CTL clock driver
      
        Updates:
         - Allocate clk_ops dynamically for SCMI clk driver
         - Add support in qcom RCG and RCG2 for multiple configurations for
           the same frequency
         - Use above support for IPQ8074 NSS port 5 and 6 clocks to resolve
           issues
         - Fix the Qualcomm APSS IPQ5018 PLL to fix boot failures of some
           boards
         - Cleanups and fixes for Qualcomm Stromer PLLs
         - Reduce max CPU frequency on Qualcomm APSS IPQ5018
         - Fix Kconfig dependencies of Qualcomm SM8650 GPU and SC8280XP camera
           clk drivers
         - Make Qualcomm MSM8998 Venus clocks functional
         - Cleanup downstream remnants related to DisplayPort across Qualcomm
           SM8450, SM6350, SM8550, and SM8650
         - Reuse the Huayra APSS register map on Qualcomm MSM8996 CBF PLL
         - Use a specific Qualcomm QCS404 compatible for the otherwise generic
           HFPLL
         - Remove Qualcomm SM8150 CPUSS AHB clk as it is unused
         - Remove an unused field in the Qualcomm RPM clk driver
         - Add missing MODULE_DEVICE_TABLE to Qualcomm MSM8917 and MSM8953
           global clock controller drivers
         - Allow choice of manual or firmware-driven control over PLLs, needed
           to fully implement CPU clock controllers on Exynos850
         - Correct PLL clock IDs on ExynosAutov9
         - Propagate certain clock rates to allow setting proper SPI clock
           rates on Google GS101
         - Mark certain Google GS101 clocks critical
         - Convert old S3C64xx clock controller bindings to DT schema
         - Add new PLL rate and missing mux on Rockchip rk3568
         - Add missing reset line on Rockchip rk3588

         - Convert to platform remove callback returning void for i.MX8MP
           Audiomix
         - Add SPI (MSIOF) and external interrupt (INTC-EX) clocks on Renesas
           R-Car V4M
         - Add interrupt controller (PLIC) clock and reset on Renesas RZ/Five
         - Prepare power domain support for Renesas RZ/G2L family members, and
           add actual support on Renesas RZ/G3S SoC

       "This adds support for IORING_CQE_F_SOCK_NONEMPTY for io_uring accept

        This is very similar to previous work that enabled the same hint for
        doing receives on sockets. By far the majority of the work here is
        refactoring to enable the networking side to pass back whether or not
        the socket had more pending requests after accepting the current one,
        the last patch just wires it up for io_uring.
      
        Not only does this enable applications to know whether there are more
        connections to accept right now, it also enables smarter logic for
        io_uring multishot accept on whether to retry immediately or wait for

      kprobe/ftrace: fix build error due to bad function definition · 4b377b48
      Linus Torvalds authored
      Commit 1a7d0890 ("kprobe/ftrace: bail out if ftrace was killed")
      introduced a bad K&R function definition, which we haven't accepted in a
      long long time.
      
      Gcc seems to let it slide, but clang notices with the appropriate error:
      
        kernel/kprobes.c:1140:24: error: a function declaration without a prototype is deprecated in all >
         1140 | void kprobe_ftrace_kill()

              |                         void
      
      but this commit was apparently never in linux-next before it was sent
      upstream, so it didn't get the appropriate build test coverage.

         - Improve timerlat auto-analysis output by replacing '\t' with spaces
           to avoid copy-and-paste issues when reporting problems.
      
         - Make the user-space (-u) option the default, as it is the most
           complete test. Add a -k option to use the in-kernel workload.
      
         - On timerlat top and hist, add a summary with the overall results.
           For instance, the minimum value for all CPUs, the overall average
           and the maximum value from all CPUs.
      
         - timerlat hist was printing initial values (i.e., 0 as max, and ~0
           as min) if the trace stopped before the first Ret-User event. This
           problem was fixed by printing the " - " no value string to the
           output if that was the case.
      
        For all RTLA tools:
      
         - Add a --warm-up <seconds> option, allowing the workload to run for
           <seconds> before starting to collect results.
      
         - Add a --trace-buffer-size option, allowing the user to set the
           tracing buffer size for -t option. This option is mainly useful for
           reducing the trace file. Now rtla depends on libtracefs >= 1.6.
      
         - Fix the -t [trace_file] parsing, now it does not require the '='
           before the option parameter, and better handles the multiple ways a
           user can pass the trace_file.txt"

      Pull tracing user-event updates from Steven Rostedt:
      
       - Minor update to the user_events interface
      
        The ABI of creating a user event states that the fields are separated
        by semicolons, and spaces should be ignored.
      
        But the parsing expected at least one space to be there (which was
        incorrect). Fix the reading of the string to handle fields separated
        by semicolons but no space between them.
      
        This does extend the API sightly as now "field;field" will now be
        parsed and not cause an error. But it should not cause any regressions
        as no logic should expect it to fail.
      
        Note, that the logic that parses the event fields to create the
        trace_event works with no spaces after the semi-colon. It is
        the logic that tests against existing events that is inconsistent.
        This causes registering an event without using spaces to succeed
        if it doesn't exist, but makes the same call that tries to register
        to the same event, but doesn't use spaces, fail.

      Pull tracing ring buffer updates from Steven Rostedt:
       "Add ring_buffer memory mappings.
      
        The tracing ring buffer was created based on being mostly used with
        the splice system call. It is broken up into page ordered sub-buffers
        and the reader swaps a new sub-buffer with an existing sub-buffer
        that's part of the write buffer. It then has total access to the
        swapped out sub-buffer and can do copyless movements of the memory
        into other mediums (file system, network, etc).
      
        The buffer is great for passing around the ring buffer contents in the
        kernel, but is not so good for when the consumer is the user space
        task itself.
      
        A new interface is added that allows user space to memory map the ring
        buffer. It will get all the write sub-buffers as well as reader
        sub-buffer (that is not written to). It can send an ioctl to change
        which sub-buffer is the new reader sub-buffer.
      
        The ring buffer is read only to user space. It only needs to call the
        ioctl when it is finished with a sub-buffer and needs a new sub-buffer
        that the writer will not write over.
      
        A self test program was also created for testing and can be used as an
        example for the interface to user space. The libtracefs (external to
        the kernel) also has code that interacts with this, although it is
        disabled until the interface is in a official release. It can be
        enabled by compiling the library with a special flag. This was used
        for testing applications that perform better with the buffer being
        mapped.
      
        Memory mapped buffers have limitations. The main one is that it can
        not be used with the snapshot logic. If the buffer is mapped,
        snapshots will be disabled. If any logic is set to trigger snapshots
        on a buffer, that buffer will not be allowed to be mapped"

         net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline
         through their respective subsystems making the next release the most
         likely place where the final series that removes the check for

      l2tp: fix ICMP error handling for UDP-encap sockets · 6e828dc6
      Tom Parkin authored
      Since commit a36e185e
      ("udp: Handle ICMP errors for tunnels with same destination port on both endpoints")
      UDP's handling of ICMP errors has allowed for UDP-encap tunnels to
      determine socket associations in scenarios where the UDP hash lookup
      could not.
      
      Subsequently, commit d26796ae
      ("udp: check udp sock encap_type in __udp_lib_err")
      subtly tweaked the approach such that UDP ICMP error handling would be
      skipped for any UDP socket which has encapsulation enabled.
      
      In the case of L2TP tunnel sockets using UDP-encap, this latter
      modification effectively broke ICMP error reporting for the L2TP
      control plane.
      
      To a degree this isn't catastrophic inasmuch as the L2TP control
      protocol defines a reliable transport on top of the underlying packet
      switching network which will eventually detect errors and time out.
      
      However, paying attention to the ICMP error reporting allows for more
      timely detection of errors in L2TP userspace, and aids in debugging
      connectivity issues.
      
      Reinstate ICMP error handling for UDP encap L2TP tunnels:
      
       * implement struct udp_tunnel_sock_cfg .encap_err_rcv in order to allow
         the L2TP code to handle ICMP errors;
      
       * only implement error-handling for tunnels which have a managed
         socket: unmanaged tunnels using a kernel socket have no userspace to
         report errors back to;
      
       * flag the error on the socket, which allows for userspace to get an
         error such as -ECONNREFUSED back from sendmsg/recvmsg;
      
       * pass the error into ip[v6]_icmp_error() which allows for userspace to
         get extended error information via. MSG_ERRQUEUE.

      idpf: don't skip over ethtool tcp-data-split setting · 67708158
      Michal Schmidt authored
      Disabling tcp-data-split on idpf silently fails:
        # ethtool -G $NETDEV tcp-data-split off
        # ethtool -g $NETDEV | grep 'TCP data split'
        TCP data split:        on
      
      But it works if you also change 'tx' or 'rx':
        # ethtool -G $NETDEV tcp-data-split off tx 256
        # ethtool -g $NETDEV | grep 'TCP data split'
        TCP data split:        off
      
      The bug is in idpf_set_ringparam, where it takes a shortcut out if the
      TX and RX sizes are not changing. Fix it by checking also if the
      tcp-data-split setting remains unchanged. Only then can the soft reset
      be skipped.

      bonding: fix oops during rmmod · a45835a0
      Tony Battersby authored
      "rmmod bonding" causes an oops ever since commit cc317ea3 ("bonding:
      remove redundant NULL check in debugfs function").  Here are the relevant
      functions being called:
      
      bonding_exit()
        bond_destroy_debugfs()
          debugfs_remove_recursive(bonding_debug_root);
          bonding_debug_root = NULL; <--------- SET TO NULL HERE
        bond_netlink_fini()
          rtnl_link_unregister()
            __rtnl_link_unregister()
              unregister_netdevice_many_notify()
                bond_uninit()
                  bond_debug_unregister()
                    (commit removed check for bonding_debug_root == NULL)
                    debugfs_remove()
                    simple_recursive_removal()
                      down_write() -> OOPS
      
      However, reverting the bad commit does not solve the problem completely
      because the original code contains a race that could cause the same
      oops, although it was much less likely to be triggered unintentionally:
      
      CPU1
        rmmod bonding
          bonding_exit()
            bond_destroy_debugfs()
              debugfs_remove_recursive(bonding_debug_root);
      
      CPU2
        echo -bond0 > /sys/class/net/bonding_masters
          bond_uninit()
            bond_debug_unregister()
              if (!bonding_debug_root)
      
      CPU1
              bonding_debug_root = NULL;
      
      So do NOT revert the bad commit (since the removed checks were racy
      anyway), and instead change the order of actions taken during module
      removal.  The same oops can also happen if there is an error during
      module init, so apply the same fix there.

      net/ipv6: Fix route deleting failure when metric equals 0 · bb487272
      xu xin authored
      Problem
      =========
      After commit 67f69513 ("ipv6: Move setting default metric for routes"),
      we noticed that the logic of assigning the default value of fc_metirc
      changed in the ioctl process. That is, when users use ioctl(fd, SIOCADDRT,
      rt) with a non-zero metric to add a route,  then they may fail to delete a
      route with passing in a metric value of 0 to the kernel by ioctl(fd,
      SIOCDELRT, rt). But iproute can succeed in deleting it.
      
      As a reference, when using iproute tools by netlink to delete routes with
      a metric parameter equals 0, like the command as follows:
      
      	ip -6 route del fe80::/64 via fe81::5054:ff:fe11:3451 dev eth0 metric 0
      
      the user can still succeed in deleting the route entry with the smallest
      metric.
      
      Root Reason
      ===========
      After commit 67f69513 ("ipv6: Move setting default metric for routes"),
      When ioctl() pass in SIOCDELRT with a zero metric, rtmsg_to_fib6_config()
      will set a defalut value (1024) to cfg->fc_metric in kernel, and in
      ip6_route_del() and the line 4074 at net/ipv3/route.c, it will check by
      
      	if (cfg->fc_metric && cfg->fc_metric != rt->fib6_metric)
      		continue;
      
      and the condition is true and skip the later procedure (deleting route)
      because cfg->fc_metric != rt->fib6_metric. But before that commit,
      cfg->fc_metric is still zero there, so the condition is false and it
      will do the following procedure (deleting).
      
      Solution
      ========
      In order to keep a consistent behaviour across netlink() and ioctl(), we
      should allow to delete a route with a metric value of 0. So we only do
      the default setting of fc_metric in route adding.
