        <link>http://kernelsources.org:8080/source/history/linux/arch/arc/Kbuild#1b294a1f35616977caddaddf3e9d28e576a1adbc</link>
        <description>Merge tag &apos;net-next-6.10&apos; of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: &quot;Core &amp; protocols:   - Complete rework of garbage collection of AF_UNIX sockets.     AF_UNIX is prone to forming reference count cycles due to fd     passing functionality. New method based on Tarjan&apos;s Strongly     Connected Components algorithm should be both faster and remove a     lot of workarounds we accumulated over the years.   - Add TCP fraglist GRO support, allowing chaining multiple TCP     packets and forwarding them together. Useful for small switches /     routers which lack basic checksum offload in some scenarios (e.g.     PPPoE).   - Support using SMP threads for handling packet backlog i.e. packet     processing from software interfaces and old drivers which don&apos;t use     NAPI. This helps move the processing out of the softirq jumble.   - Continue work of converting from rtnl lock to RCU protection.     Don&apos;t require rtnl lock when reading: IPv6 routing FIB, IPv6     address labels, netdev threaded NAPI sysfs files, bonding driver&apos;s     sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,     TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot     of the link information available via rtnetlink.   - Small optimizations from Eric to UDP wake up handling, memory     accounting, RPS/RFS implementation, TCP packet sizing etc.   - Allow direct page recycling in the bulk API used by XDP, for +2%     PPS.   - Support peek with an offset on TCP sockets.   - Add MPTCP APIs for querying last time packets were received/sent/acked     and whether MPTCP &quot;upgrade&quot; succeeded on a TCP socket.   - Add intra-node communication shortcut to improve SMC performance.   - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol     driver.   - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.   - Add reset reasons for tracing what caused a TCP reset to be sent.   - Introduce direction attribute for xfrm (IPSec) states. State can be     used either for input or output packet processing.  Things we sprinkled into general kernel code:   - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().     This required touch-ups and renaming of a few existing users.   - Add Endian-dependent __counted_by_{le,be} annotations.   - Make building selftests &quot;quieter&quot; by printing summaries like     &quot;CC object.o&quot; rather than full commands with all the arguments.  Netfilter:   - Use GFP_KERNEL to clone elements, to deal better with OOM     situations and avoid failures in the .commit step.  BPF:   - Add eBPF JIT for ARCv2 CPUs.   - Support attaching kprobe BPF programs through kprobe_multi link in     a session mode, meaning, a BPF program is attached to both function     entry and return, the entry program can decide if the return     program gets executed and the entry program can share u64 cookie     value with return program. &quot;Session mode&quot; is a common use-case for     tetragon and bpftrace.   - Add the ability to specify and retrieve BPF cookie for raw     tracepoint programs in order to ease migration from classic to raw     tracepoints.   - Add an internal-only BPF per-CPU instruction for resolving per-CPU     memory addresses and implement support in x86, ARM64 and RISC-V     JITs. This allows inlining functions which need to access per-CPU     state.   - Optimize x86 BPF JIT&apos;s emit_mov_imm64, and add support for various     atomics in bpf_arena which can be JITed as a single x86     instruction. Support BPF arena on ARM64.   - Add a new bpf_wq API for deferring events and refactor     process-context bpf_timer code to keep common code where possible.   - Harden the BPF verifier&apos;s and/or/xor value tracking.   - Introduce crypto kfuncs to let BPF programs call kernel crypto     APIs.   - Support bpf_tail_call_static() helper for BPF programs with GCC 13.   - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF     program to have code sections where preemption is disabled.  Driver API:   - Skip software TC processing completely if all installed rules are     marked as HW-only, instead of checking the HW-only flag rule by     rule.   - Add support for configuring PoE (Power over Ethernet), similar to     the already existing support for PoDL (Power over Data Line)     config.   - Initial bits of a queue control API, for now allowing a single     queue to be reset without disturbing packet flow to other queues.   - Common (ethtool) statistics for hardware timestamping.  Tests and tooling:   - Remove the need to create a config file to run the net forwarding     tests so that a naive &quot;make run_tests&quot; can exercise them.   - Define a method of writing tests which require an external endpoint     to communicate with (to send/receive data towards the test     machine). Add a few such tests.   - Create a shared code library for writing Python tests. Expose the     YAML Netlink library from tools/ to the tests for easy Netlink     access.   - Move netfilter tests under net/, extend them, separate performance     tests from correctness tests, and iron out issues found by running     them &quot;on every commit&quot;.   - Refactor BPF selftests to use common network helpers.   - Further work filling in YAML definitions of Netlink messages for:     nftables, team driver, bonding interfaces, vlan interfaces, VF     info, TC u32 mark, TC police action.   - Teach Python YAML Netlink to decode attribute policies.   - Extend the definition of the &quot;indexed array&quot; construct in the specs     to cover arrays of scalars rather than just nests.   - Add hyperlinks between definitions in generated Netlink docs.  Drivers:   - Make sure unsupported flower control flags are rejected by drivers,     and make more drivers report errors directly to the application     rather than dmesg (large number of driver changes from Asbj&#248;rn     Sloth T&#248;nnesen).   - Ethernet high-speed NICs:      - Broadcom (bnxt):         - support multiple RSS contexts and steering traffic to them         - support XDP metadata         - make page pool allocations more NUMA aware      - Intel (100G, ice, idpf):         - extract datapath code common among Intel drivers into a library         - use fewer resources in switchdev by sharing queues with the PF         - add PFCP filter support         - add Ethernet filter support         - use a spinlock instead of HW lock in PTP clock ops         - support 5 layer Tx scheduler topology      - nVidia/Mellanox:         - 800G link modes and 100G SerDes speeds         - per-queue IRQ coalescing configuration      - Marvell Octeon:         - support offloading TC packet mark action   - Ethernet NICs consumer, embedded and virtual:      - stop lying about skb-&gt;truesize in USB Ethernet drivers, it        messes up TCP memory calculations      - Google cloud vNIC:         - support changing ring size via ethtool         - support ring reset using the queue control API      - VirtIO net:         - expose flow hash from RSS to XDP         - per-queue statistics         - add selftests      - Synopsys (stmmac):         - support controllers which require an RX clock signal from the           MII bus to perform their hardware initialization      - TI:         - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices         - icssg_prueth: add SW TX / RX Coalescing based on hrtimers         - cpsw: minimal XDP support      - Renesas (ravb):         - support describing the MDIO bus      - Realtek (r8169):         - add support for RTL8168M      - Microchip Sparx5:         - matchall and flower actions mirred and redirect   - Ethernet switches:      - nVidia/Mellanox:         - improve events processing performance      - Marvell:         - add support for MV88E6250 family internal PHYs      - Microchip:         - add DCB and DSCP mapping support for KSZ switches         - vsc73xx: convert to PHYLINK      - Realtek:         - rtl8226b/rtl8221b: add C45 instances and SerDes switching   - Many driver changes related to PHYLIB and PHYLINK deprecated API     cleanup   - Ethernet PHYs:      - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY.      - micrel: lan8814: add support for PPS out and external timestamp trigger   - WiFi:      - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices        drivers.

        <description>Merge tag &apos;for-netdev&apos; of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-nextDaniel Borkmann says:====================pull-request: bpf-next 2024-05-13We&apos;ve added 119 non-merge commits during the last 14 day(s) which containa total of 134 files changed, 9462 insertions(+), 4742 deletions(-).The main changes are:1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi.2) Add BPF range computation improvements to the verifier in particular   around XOR and OR operators, refactoring of checks for range computation   and relaxing MUL range computation so that src_reg can also be an unknown   scalar, from Cupertino Miranda.3) Add support to attach kprobe BPF programs through kprobe_multi link in   a session mode, meaning, a BPF program is attached to both function entry   and return, the entry program can decide if the return program gets   executed and the entry program can share u64 cookie value with return   program. Session mode is a common use-case for tetragon and bpftrace,   from Jiri Olsa.4) Fix a potential overflow in libbpf&apos;s ring__consume_n() and improve libbpf   as well as BPF selftest&apos;s struct_ops handling, from Andrii Nakryiko.5) Improvements to BPF selftests in context of BPF gcc backend,   from Jose E. Marchesi &amp; David Faust.6) Migrate remaining BPF selftest tests from test_sock_addr.c to prog_test-   -style in order to retire the old test, run it in BPF CI and additionally   expand test coverage, from Jordan Rife.7) Big batch for BPF selftest refactoring in order to remove duplicate code   around common network helpers, from Geliang Tang.8) Another batch of improvements to BPF selftests to retire obsolete   bpf_tcp_helpers.h as everything is available vmlinux.h,   from Martin KaFai Lau.9) Fix BPF map tear-down to not walk the map twice on free when both timer   and wq is used, from Benjamin Tissoires.10) Fix BPF verifier assumptions about socket-&gt;sk that it can be non-NULL,    from Alexei Starovoitov.11) Change BTF build scripts to using --btf_features for pahole v1.26+,    from Alan Maguire.12) Small improvements to BPF reusing struct_size() and krealloc_array(),    from Andy Shevchenko.13) Fix s390 JIT to emit a barrier for BPF_FETCH instructions,    from Ilya Leoshkevich.14) Extend TCP -&gt;cong_control() callback in order to feed in ack and    flag parameters and allow write-access to tp-&gt;snd_cwnd_stamp    from BPF program, from Miao Xu.15) Add support for internal-only per-CPU instructions to inline    bpf_get_smp_processor_id() helper call for arm64 and riscv64 BPF JITs,    from Puranjay Mohan.16) Follow-up to remove the redundant ethtool.h from tooling infrastructure,    from Tushar Vyavahare.17) Extend libbpf to support &quot;module:&lt;function&gt;&quot; syntax for tracing    programs, from Viktor Malik.* tag &apos;for-netdev&apos; of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (119 commits)  bpf: make list_for_each_entry portable  bpf: ignore expected GCC warning in test_global_func10.c  bpf: disable strict aliasing in test_global_func9.c  selftests/bpf: Free strdup memory in xdp_hw_metadata  selftests/bpf: Fix a few tests for GCC related warnings.  bpf: avoid gcc overflow warning in test_xdp_vlan.c  tools: remove redundant ethtool.h from tooling infra  selftests/bpf: Expand ATTACH_REJECT tests  selftests/bpf: Expand getsockname and getpeername tests  sefltests/bpf: Expand sockaddr hook deny tests  selftests/bpf: Expand sockaddr program return value tests  selftests/bpf: Retire test_sock_addr.(c|sh)  selftests/bpf: Remove redundant sendmsg test cases  selftests/bpf: Migrate ATTACH_REJECT test cases  selftests/bpf: Migrate expected_attach_type tests  selftests/bpf: Migrate wildcard destination rewrite test  selftests/bpf: Migrate sendmsg6 v4 mapped address tests  selftests/bpf: Migrate sendmsg deny test cases  selftests/bpf: Migrate WILDCARD_IP test  selftests/bpf: Handle SYSCALL_EPERM and SYSCALL_ENOTSUPP test cases  ...====================Link: https://lore.kernel.org/r/20240513134114.17575-1-daniel@iogearbox.netSigned-off-by: Jakub Kicinski &lt;kuba@kernel.org&gt;

        <title>f122668ddcce450c2585f0be4bf4478d6fd6176b - ARC: Add eBPF JIT support</title>
        <link>http://kernelsources.org:8080/source/history/linux/arch/arc/Kbuild#f122668ddcce450c2585f0be4bf4478d6fd6176b</link>
        <description>ARC: Add eBPF JIT supportThis will add eBPF JIT support to the 32-bit ARCv2 processors. Theimplementation is qualified by running the BPF tests on a Synopsys HSDKboard with &quot;ARC HS38 v2.1c at 500 MHz&quot; as the 4-core CPU.The test_bpf.ko reports 2-10 fold improvements in execution time of itstests. For instance:test_bpf: #33 tcpdump port 22 jited:0 704 1766 2104 PASStest_bpf: #33 tcpdump port 22 jited:1 120  224  260 PASStest_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:0 238 PASStest_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:1  23 PASStest_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:0 2034681 PASStest_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:1 1020022 PASSDeployment and structure------------------------The related codes are added to &quot;arch/arc/net&quot;:- bpf_jit.h       -- The interface that a back-end translator must provide- bpf_jit_core.c  -- Knows how to handle the input eBPF byte stream- bpf_jit_arcv2.c -- The back-end code that knows the translation logicThe bpf_int_jit_compile() at the end of bpf_jit_core.c is the entranceto the whole process. Normally, the translation is done in one pass,namely the &quot;normal pass&quot;. In case some relocations are not known duringthis pass, some data (arc_jit_data) is allocated for the next pass tocome. This possible next (and last) pass is called the &quot;extra pass&quot;.1. Normal pass       # The necessary pass     1a. Dry run       # Get the whole JIT length, epilogue offset, etc.     1b. Emit phase    # Allocate memory and start emitting instructions2. Extra pass        # Only needed if there are relocations to be fixed     2a. Patch relocationsSupport status--------------The JIT compiler supports BPF instructions up to &quot;cpu=v4&quot;.
