      libbpf: Fix no-args func prototype BTF dumping syntax · 189f1a97
      Andrii Nakryiko authored
      For all these years libbpf's BTF dumper has been emitting not strictly
      valid syntax for function prototypes that have no input arguments.
      
      Instead of `int (*blah)()` we should emit `int (*blah)(void)`.
      
      This is not normally a problem, but it manifests when we get kfuncs in
      vmlinux.h that have no input arguments. Due to compiler internal
      specifics, we get no BTF information for such kfuncs, if they are not
      declared with proper `(void)`.
      
      The fix is trivial. We also need to adjust a few ancient tests that
      happily assumed `()` is correct.
      
      Fixes: 351131b5 ("libbpf: add btf_dump API for BTF-to-C conversion")

      MAINTAINERS: Update powerpc BPF JIT maintainers · c638b130
      Naveen N Rao authored
      Hari Bathini has been updating and maintaining the powerpc BPF JIT since
      a while now. Christophe Leroy has been doing the same for 32-bit
      powerpc. Add them as maintainers for the powerpc BPF JIT.
      
      I am no longer actively looking into the powerpc BPF JIT. Change my role
      to that of a reviewer so that I can help with the odd query.

      selftests/bpf: fexit_sleep: Fix stack allocation for arm64 · e1ef78dc
      Puranjay Mohan authored
      On ARM64 the stack pointer should be aligned at a 16 byte boundary or
      the SPAlignmentFault can occur. The fexit_sleep selftest allocates the
      stack for the child process as a character array, this is not guaranteed
      to be aligned at 16 bytes.
      
      Because of the SPAlignmentFault, the child process is killed before it
      can do the nanosleep call and hence fentry_cnt remains as 0. This causes
      the main thread to hang on the following line:
      
      while (READ_ONCE(fexit_skel->bss->fentry_cnt) != 2);
      
      Fix this by allocating the stack using mmap() as described in the
      example in the man page of clone().
      
      Remove the fexit_sleep test from the DENYLIST of arm64.

      eth: fbnic: fix s390 build. · 0e03c643
      Paolo Abeni authored
      Building the fbnic nn s390, yield a build bug:
      
      In function ‘fbnic_config_drop_mode_rcq’,
          inlined from ‘fbnic_enable’ at drivers/net/ethernet/meta/fbnic/fbnic_txrx.c:1836:4:
      ././include/linux/compiler_types.h:510:45: error: call to ‘__compiletime_assert_919’ declared with attribute error: FIELD_PREP: value too large for the field
      
      The relevant mask is 9 bits wide, and the related value is the cacheline
      aligned size of struct skb_shared_info.
      
      On s390 the cacheline size is 256 bytes, and skb_shared_info minimum
      size on 64 bits system is 320 bytes.
      
      Avoid building the driver for such arch.

      Pull networking updates from Jakub Kicinski:
       "Not much excitement - a handful of large patchsets (devmem among them)
        did not make it in time.
      
        Core & protocols:
      
         - Use local_lock in addition to local_bh_disable() to protect per-CPU
           resources in networking, a step closer for local_bh_disable() not
           to act as a big lock on PREEMPT_RT
      
         - Use flex array for netdevice priv area, ensure its cache alignment
      
         - Add a sysctl knob to allow user to specify a default rto_min at
           socket init time. Bit of a big hammer but multiple companies were
           independently carrying such patch downstream so clearly it's useful
      
         - Support scheduling transmission of packets based on CLOCK_TAI
      
         - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
           off using cpusets
      
         - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address
      
         - Allow configuration of multipath hash seed, to both allow
           synchronizing hashing of two routers, and preventing partial
           accidental sync
      
         - Improve TCP compliance with RFC 9293 for simultaneous connect()
      
         - Support sending NAT keepalives in IPsec ESP in UDP states.
           Userspace IKE daemon had to do this before, but the kernel can
           better keep track of it
      
         - Support sending supervision HSR frames with MAC addresses stored in
           ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled
      
         - Introduce IPPROTO_SMC for selecting SMC when socket is created
      
         - Allow UDP GSO transmit from devices with no checksum offload
      
         - openvswitch: add packet sampling via psample, separating the
           sampled traffic from "upcall" packets sent to user space for
           forwarding
      
         - nf_tables: shrink memory consumption for transaction objects
      
        Things we sprinkled into general kernel code:
      
         - Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
           QCA6390)           [ Already merged separately - Linus ]
      
         - Add IRQ information in sysfs for auxiliary bus
      
         - Introduce guard definition for local_lock
      
         - Add aligned flavor of __cacheline_group_{begin, end}() markings for
           grouping fields in structures
      
        BPF:
      
         - Notify user space (via epoll) when a struct_ops object is getting
           detached/unregistered
      
         - Add new kfuncs for a generic, open-coded bits iterator
      
         - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
           bpf_list_head
      
         - Support resilient split BTF which cuts down on duplication and
           makes BTF as compact as possible WRT BTF from modules
      
         - Add support for dumping kfunc prototypes from BTF which enables
           both detecting as well as dumping compilable prototypes for kfuncs
      
         - riscv64 BPF JIT improvements in particular to add 12-argument
           support for BPF trampolines and to utilize bpf_prog_pack for the
           latter
      
         - Add the capability to offload the netfilter flowtable in XDP layer
           through kfuncs
      
        Driver API:
      
         - Allow users to configure IRQ tresholds between which automatic IRQ
           moderation can choose
      
         - Expand Power Sourcing (PoE) status with power, class and failure
           reason. Support setting power limits
      
         - Track additional RSS contexts in the core, make sure configuration
           changes don't break them
      
         - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
           ESP data paths
      
         - Support updating firmware on SFP modules
      
        Tests and tooling:
      
         - mptcp: use net/lib.sh to manage netns
      
         - TCP-AO and TCP-MD5: replace debug prints used by tests with

      um: Use generic runtime constant implementation · 17e6a121
      Linus Torvalds authored
      UML should not be using the architecture native runtime constants, since
      that requires also having the appropriate instruction fixups (and all
      the linker script details).
      
      Not that using that code would be impossible, but it's not worth it.
      Just point UML at the generic version.

      Pull sysctl updates from Joel Granados:
      
       - Remove "->procname == NULL" check when iterating through sysctl table
         arrays
      
         Removing sentinels in ctl_table arrays reduces the build time size
         and runtime memory consumed by ~64 bytes per array. With all
         ctl_table sentinels gone, the additional check for ->procname == NULL
         that worked in tandem with the ARRAY_SIZE to calculate the size of
         the ctl_table arrays is no longer needed and has been removed. The
         sysctl register functions now returns an error if a sentinel is used.
      
       - Preparation patches for sysctl constification
      
         Constifying ctl_table structs prevents the modification of
         proc_handler function pointers as they would reside in .rodata. The
         ctl_table arguments in sysctl utility functions are const qualified
         in preparation for a future treewide proc_handler argument
         constification commit.
      
       - Misc fixes
      
         Increase robustness of set_ownership by providing sane default
         ownership values in case the callee doesn't set them. Bound check
         proc_dou8vec_minmax to avoid loading buggy modules and give sysctl
         testing module a name to avoid compiler complaints.

       "Note the removal of the EFI fake memory map support - this is believed

        bring it back if needed.
      
        With recent developments regarding confidential VMs and unaccepted
        memory, combined with kexec, creating a known inaccurate view of the
        firmware's memory map and handing it to the OS is a feature we can
        live without, hence the removal. Alternatively, I could imagine making
        this feature mutually exclusive with those confidential VM related
        features, but let's try simply removing it first.
      
        Summary:
      
         - Drop support for the 'fake' EFI memory map on x86
      
         - Add an SMBIOS based tweak to the EFI stub instructing the firmware

      Pull SoC dt updates from Arnd Bergmann:
       "The devicetree updates are fairly well spread out across platforms,
        with Qualcomm making up about a third of the total.
      
        There are three new SoCs in existing product families this:
      
         - NXP i.MX95 is a variant of i.MX93, now with six Cortex-A55 cores
           instead of just two as well as a GPU and more high-speed I/O
           devices.
      
         - Qualcomm QCS8550 is a variant of SM8550 for IOT devices
      
         - Airoha EN7581 is a 10G-PON network chip and related to the MT7981
           Wireless router chip from its parent Mediatek.
      
        In total there are 58 new machines, including four riscv boards and
        eight for 32-bit arm.
      
        The most exciting new addition is probably a pair of laptops based on
        the Qualcomm x1e80100 (Snapdragon X1 Elite) chip, the Asus Vivobook
        S15 and the Lenovo Yoga Slim7x.
      
        Other noteworthy new additions are:
      
         - A total of 20 Qualcomm based machines, mostly Android devices from
           Samsung, Motorola and LG, as well as a wireless router and some
           reference designs
      
         - Six NXP i.MX based machines, mostly industrial boards along with
           some reference designs
      
         - Mediatek sees some interesting Filogic based routers including the
           "OpenWRT One", a few new Chromebooks as well as single-board
           computers.
      
         - Four machines from Solidrun based on Marvell cn913x, replacing the
           older Armada 8000 based counterparts
      
         - The four Amlogic machines are all set top boxes or reference
           designs for them
      
         - The nine new Rockchips machines are mostly single-board computers
           including some interesting ones based on the rk3588 chip like the
           ROCK 5 ITX board and the CM3588 with its four NVMe slots
      
         - The RISC-V boards are all single-board computers based on Starfive
           JH7110, Microchip MPFS and Allwinner D1, which all had similar
           boards already
      
        There are also a lot of updates to already supported machines, notably
        for the TI K3, Rockchips, Freescale and of course Qualcomm platforms"

        SoCs in platform drivers, a new "protection domain mapper" driver, and
        a "shared memory bridge" driver.
      
        The cznic "turris omnia" router based on Marvell Armada gets a
        platform driver that talks to the board specific microcontroller.

      tcp: Replace strncpy() with strscpy() · a3bfc095
      Kees Cook authored
      Replace the deprecated[1] uses of strncpy() in tcp_ca_get_name_by_key()
      and tcp_get_default_congestion_control(). The callers use the results as
      standard C strings (via nla_put_string() and proc handlers respectively),
      so trailing padding is not needed.
      
      Since passing the destination buffer arguments decays it to a pointer,
      the size can't be trivially determined by the compiler. ca->name is
      the same length in both cases, so strscpy() won't fail (when ca->name
      is NUL-terminated). Include the length explicitly instead of using the
      2-argument strscpy().
