      net: liquidio: fix clang-specific W=1 build warnings · cbdd50ec
      Dmitry Antipov authored
      When compiling with clang-18 and W=1, I've noticed the following
      warnings:
      
      drivers/net/ethernet/cavium/liquidio/cn23xx_pf_device.c:1493:16: warning: cast
      from 'void (*)(struct octeon_device *, struct octeon_mbox_cmd *, void *)' to
      'octeon_mbox_callback_t' (aka 'void (*)(void *, void *, void *)') converts to
      incompatible function type [-Wcast-function-type-strict]
       1493 |         mbox_cmd.fn = (octeon_mbox_callback_t)cn23xx_get_vf_stats_callback;
            |                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      and:
      
      drivers/net/ethernet/cavium/liquidio/cn23xx_vf_device.c:432:16: warning: cast
      from 'void (*)(struct octeon_device *, struct octeon_mbox_cmd *, void *)' to
      'octeon_mbox_callback_t' (aka 'void (*)(void *, void *, void *)') converts to
      incompatible function type [-Wcast-function-type-strict]
        432 |         mbox_cmd.fn = (octeon_mbox_callback_t)octeon_pfvf_hs_callback;
            |                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      Fix both of the above by adjusting 'octeon_mbox_callback_t' to match actual
      callback definitions (at the cost of adding an extra forward declaration).

      Pull networking updates from Paolo Abeni:
       "The most interesting thing is probably the networking structs
        reorganization and a significant amount of changes is around
        self-tests.
      
        Core & protocols:
      
         - Analyze and reorganize core networking structs (socks, netdev,
           netns, mibs) to optimize cacheline consumption and set up build
           time warnings to safeguard against future header changes
      
           This improves TCP performances with many concurrent connections up
           to 40%
      
         - Add page-pool netlink-based introspection, exposing the memory
           usage and recycling stats. This helps indentify bad PP users and
           possible leaks
      
         - Refine TCP/DCCP source port selection to no longer favor even
           source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
           lowers the time taken by connect() for hosts having many active
           connections to the same destination
      
         - Refactor the TCP bind conflict code, shrinking related socket
           structs
      
         - Refactor TCP SYN-Cookie handling, as a preparation step to allow
           arbitrary SYN-Cookie processing via eBPF
      
         - Tune optmem_max for 0-copy usage, increasing the default value to
           128KB and namespecifying it
      
         - Allow coalescing for cloned skbs coming from page pools, improving
           RX performances with some common configurations
      
         - Reduce extension header parsing overhead at GRO time
      
         - Add bridge MDB bulk deletion support, allowing user-space to
           request the deletion of matching entries
      
         - Reorder nftables struct members, to keep data accessed by the
           datapath first
      
         - Introduce TC block ports tracking and use. This allows supporting
           multicast-like behavior at the TC layer
      
         - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
           classifiers (RSVP and tcindex)
      
         - More data-race annotations
      
         - Extend the diag interface to dump TCP bound-only sockets
      
         - Conditional notification of events for TC qdisc class and actions
      
         - Support for WPAN dynamic associations with nearby devices, to form
           a sub-network using a specific PAN ID
      
         - Implement SMCv2.1 virtual ISM device support
      
         - Add support for Batman-avd mulicast packet type
      
        BPF:
      
         - Tons of verifier improvements:
             - BPF register bounds logic and range support along with a large
               test suite
             - log improvements
             - complete precision tracking support for register spills
             - track aligned STACK_ZERO cases as imprecise spilled registers.
               This improves the verifier "instructions processed" metric from
               single digit to 50-60% for some programs
             - support for user's global BPF subprogram arguments with few
               commonly requested annotations for a better developer
               experience
             - support tracking of BPF_JNE which helps cases when the compiler
               transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
               like
             - several fixes
      
         - Add initial TX metadata implementation for AF_XDP with support in
           mlx5 and stmmac drivers. Two types of offloads are supported right
           now, that is, TX timestamp and TX checksum offload
      
         - Fix kCFI bugs in BPF all forms of indirect calls from BPF into
           kernel and from kernel into BPF work with CFI enabled. This allows
           BPF to work with CONFIG_FINEIBT=y
      
         - Change BPF verifier logic to validate global subprograms lazily
           instead of unconditionally before the main program, so they can be
           guarded using BPF CO-RE techniques
      
         - Support uid/gid options when mounting bpffs
      
         - Add a new kfunc which acquires the associated cgroup of a task
           within a specific cgroup v1 hierarchy where the latter is
           identified by its id
      
         - Extend verifier to allow bpf_refcount_acquire() of a map value
           field obtained via direct load which is a use-case needed in
           sched_ext
      
         - Add BPF link_info support for uprobe multi link along with bpftool
           integration for the latter
      
         - Support for VLAN tag in XDP hints
      
         - Remove deprecated bpfilter kernel leftovers given the project is
           developed in user-space (https://github.com/facebook/bpfilter)
      
        Misc:
      
         - Support for parellel TC self-tests execution
      
         - Increase MPTCP self-tests coverage
      
         - Updated the bridge documentation, including several so-far
           undocumented features
      
         - Convert all the net self-tests to run in unique netns, to avoid
           random failures due to conflict and allow concurrent runs
      
         - Add TCP-AO self-tests
      
         - Add kunit tests for both cfg80211 and mac80211
      
         - Autogenerate Netlink families documentation from YAML spec
      
         - Add yml-gen support for fixed headers and recursive nests, the tool
           can now generate user-space code for all genetlink families for
           which we have specs
      
         - A bunch of additional module descriptions fixes
      
         - Catch incorrect freeing of pages belonging to a page pool
      
        Driver API:
      
         - Rust abstractions for network PHY drivers; do not cover yet the
           full C API, but already allow implementing functional PHY drivers
           in rust
      
         - Introduce queue and NAPI support in the netdev Netlink interface,
           allowing complete access to the device <> NAPIs <> queues
           relationship
      
         - Introduce notifications filtering for devlink to allow control
           application scale to thousands of instances
      
         - Improve PHY validation, requesting rate matching information for
           each ethtool link mode supported by both the PHY and host
      
         - Add support for ethtool symmetric-xor RSS hash
      
         - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
           platform
      
         - Expose pin fractional frequency offset value over new DPLL generic
           netlink attribute
      
         - Convert older drivers to platform remove callback returning void
      
         - Add support for PHY package MMD read/write

      Linus Torvalds authored
      Pull s390 updates from Alexander Gordeev:
      
       - Add machine variable capacity information to /proc/sysinfo.
      
       - Limit the waste of page tables and always align vmalloc area size and
         base address on segment boundary.
      
       - Fix a memory leak when an attempt to register interruption sub class
         (ISC) for the adjunct-processor (AP) guest failed.
      
       - Reset response code AP_RESPONSE_INVALID_GISA to understandable by
         guest AP_RESPONSE_INVALID_ADDRESS in response to a failed
         interruption sub class (ISC) registration attempt.
      
       - Improve reaction to adjunct-processor (AP)
         AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts
         on behalf of a guest.
      
       - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP)
         queue device bound to the vfio_ap device driver when the mediated
         device is attached to a guest, but the queue device is not passed
         through.
      
       - Rework struct ap_card to hold the whole adjunct-processor (AP) card
         hardware information. As result, all the ugly bit checks are replaced
         by simple evaluations of the required bit fields.
      
       - Improve handling of some weird scenarios between service element (SE)
         host and SE guest with adjunct-processor (AP) pass-through support.
      
       - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return
         the previous value of the to be changed control register. This is
         useful if a bit is only changed temporarily and the previous content
         needs to be restored.
      
       - The kernel starts with machine checks disabled and is expected to
         enable it once trap_init() is called. However the implementation
         allows machine checks early. Consistently enable it in trap_init()
         only.
      
       - local_mcck_disable() and local_mcck_enable() assume that machine
         checks are always enabled. Instead implement and use
         local_mcck_save() and local_mcck_restore() to disable machine checks
         and restore the previous state.
      
       - Modification of floating point control (FPC) register of a traced
         process using ptrace interface may lead to corruption of the FPC
         register of the tracing process. Fix this.
      
       - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point
         control (FPC) register in vCPU, but may lead to corruption of the FPC
         register of the host process. Fix this.
      
       - Use READ_ONCE() to read a vCPU floating point register value from the
         memory mapped area. This avoids that, depending on code generation, a
         different value is tested for validity than the one that is used.
      
       - Get rid of test_fp_ctl(), since it is quite subtle to use it
         correctly. Instead copy a new floating point control register value
         into its save area and test the validity of the new value when
         loading it.
      
       - Remove superfluous save_fpu_regs() call.
      
       - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines
         provide the vector facility since many years and the need to make the
         task structure size dependent on the vector facility does not exist.
      
       - Remove the "novx" kernel command line option, as the vector code runs
         without any problems since many years.
      
       - Add the vector facility to the z13 architecture level set (ALS). All
         hypervisors support the vector facility since many years. This allows
         compile time optimizations of the kernel.
      
       - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As
         result, the compiled code will have less runtime checks and less
         code.
      
       - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C.
      
       - Convert the struct subchannel spinlock from pointer to member.

        ioremap_uc() definition from everything except x86, which still needs
        it for pre-PAT systems. This series notably contains a patch from
        Jiaxun Yang that converts MIPS to use asm-generic/io.h like every
        other architecture does, enabling future cleanups.
      
        Some of my own patches fix -Wmissing-prototype warnings in
        architecture specific code across several architectures. This is now
        needed as the warning is enabled by default. There are still some
        remaining warnings in minor platforms, but the series should catch
        most of the widely used ones make them more consistent with one
        another.

      Pull sysctl updates from Luis Chamberlain:
       "To help make the move of sysctls out of kernel/sysctl.c not incur a
        size penalty sysctl has been changed to allow us to not require the
        sentinel, the final empty element on the sysctl array. Joel Granados
        has been doing all this work.
      
        In the v6.6 kernel we got the major infrastructure changes required to
        support this. For v6.7 we had all arch/ and drivers/ modified to
        remove the sentinel. For v6.8-rc1 we get a few more updates for fs/
        directory only.
      
        The kernel/ directory is left but we'll save that for v6.9-rc1 as
        those patches are still being reviewed. After that we then can expect
        also the removal of the no longer needed check for procname == NULL.
      
        Let us recap the purpose of this work:
      
         - this helps reduce the overall build time size of the kernel and run
           time memory consumed by the kernel by about ~64 bytes per array
      
         - the extra 64-byte penalty is no longer inncurred now when we move
           sysctls out from kernel/sysctl.c to their own files
      
        Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to
        see further work by Thomas Weißschuh with the constificatin of the
        struct ctl_table.
      
        Due to Joel Granados's work, and to help bring in new blood, I have
        suggested for him to become a maintainer and he's accepted. So for
        v6.9-rc1 I look forward to seeing him sent you a pull request for
        further sysctl changes. This also removes Iurii Zaikin as a maintainer
        as he has moved on to other projects and has had no time to help at
        all"

      Pull bcachefs updates from Kent Overstreet:
      
       - btree write buffer rewrite: instead of adding keys to the btree write
         buffer at transaction commit time, we now journal them with a
         different journal entry type and copy them from the journal to the
         write buffer just prior to journal write.
      
         This reduces the number of atomic operations on shared cachelines in
         the transaction commit path and is a signicant performance
         improvement on some workloads: multithreaded 4k random writes went
         from ~650k iops to ~850k iops.
      
       - Bring back optimistic spinning for six locks: the new implementation
         doesn't use osq locks; instead we add to the lock waitlist as normal,
         and then spin on the lock_acquired bit in the waitlist entry, _not_
         the lock itself.
      
       - New ioctls:
      
          - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types
      
          - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of
            fsck but without mounting: useful for transparently using the
            kernel version of fsck from 'bcachefs fsck' when the kernel
            version is a better match for the on disk filesystem.
      
          - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported
            yet, but the passes that are supported are fully featured - errors
            may be corrected as normal.
      
         The new ioctls use the new 'thread_with_file' abstraction for kicking
         off a kthread that's tied to a file descriptor returned to userspace
         via the ioctl.
      
       - btree_paths within a btree_trans are now dynamically growable,
         instead of being limited to 64. This is important for the
         check_directory_structure phase of fsck, and also fixes some issues
         we were having with btree path overflow in the reflink btree.
      
       - Trigger refactoring; prep work for the upcoming disk space accounting
         rewrite
      
       - Numerous bugfixes :)
