Merge tag 'bpf-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-nextPull bpf updates from Alexei Starovoitov: "Major changes: - Recover from BPF arena page faults using a scratch page and add ptep_try_set() for lockless empty-slot installs on x86 and arm64. This allows BPF kfuncs to access arena pointers directly. The 'arena_direct_access' stable branch was created for this work and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar Kartikeya Dwivedi) - Lift old restriction and support 6+ arguments in BPF programs and kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan) Other features and fixes: - Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease addition of new BTF kinds (Alan Maguire) - Raise the maximum BPF call chain depth from 8 to 16 frames (Alexei Starovoitov) - Refactor object relationship tracking in the verifier and fix a dynptr use-after-free bug (Amery Hung) - Harden the signed program loader and reject exclusive maps as inner maps (Daniel Borkmann) - Replace the verifier min/max bounds fields with a circular number (cnum) representation and improve 32->64 bit range refinements (Eduard Zingerman) - Introduce the arena library and runtime (libarena) with a buddy allocator, rbtree and SPMC queue data structures, ASAN support and a parallel test harness. Allow subprograms to return arena pointers and switch to a BTF type-tag based __arena annotation (Emil Tsalapatis) - Cache build IDs in the sleepable stackmap path and avoid faultable build ID reads under mm locks (Ihor Solodrai) - Introduce the tracing_multi link to attach a single BPF program to many kernel functions at once. Allow specifying the uprobe_multi target via FD (Jiri Olsa) - Extend the bpf_list family of kfuncs with bpf_list_add/del(), and bpf_list_is_first/is_last/empty() (Kaitao Cheng) - Extend the BPF syscall with common attributes support for prog_load, btf_load and map_create (Leon Hwang) - Wrap rhashtable as BPF map (Mykyta Yatsenko, Herbert Xu) - Add sleepable support for tracepoint programs and fix deadlocks in LRU map due to NMI reentry (Mykyta Yatsenko) - Fix OOB access in bpf_flow_keys, fix nullness analysis of inner arrays, enforce write checks for global subprograms (Nuoqi Gui) - Report the maximum combined stack depth and print a breakdown of instructions processed per subprogram (Paul Chaignon) - Add an XDP load-balancer benchmark and arm64 JIT support for stack arguments (Puranjay Mohan) - Add kfuncs to traverse over wakeup_sources (Samuel Wu) - Allow sleepable BPF programs to use LPM trie maps directly (Vlad Poenaru) - Many more fixes and cleanups across the verifier, BTF, sockmap, devmap, bpffs, security hooks, s390/riscv/loongarch JITs, rqspinlock, libbpf, bpftool, selftests"* tag 'bpf-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (336 commits) selftests/bpf: Work around llvm stack overflow in crypto progs selftests/bpf: add test for bpf_msg_pop_data() overflow bpf, sockmap: fix integer overflow in bpf_msg_pop_data() bounds check sockmap: Fix use-after-free in udp_bpf_recvmsg() bpf, sockmap: keep sk_msg copy state in sync bpf, sockmap: Fix wrong rsge offset in bpf_msg_push_data() bpf, sockmap: reject overflowing copy + len in bpf_msg_push_data() selftsets/bpf: Retry map update on helper_fill_hashmap() selftests/bpf: Add test for sleepable lsm_cgroup rejection selftests/bpf: Add test to verify the fix for bpf_setsockopt() helper bpf: Fix bpf_get/setsockopt to tos for ipv4-mapped ipv6 socket selftests/bpf: Avoid static LLVM linking for cross builds selftests/bpf: Use common CFLAGS for urandom_read selftests/bpf: Initialize operation name before use tools/bpf: build: Append extra cflags libbpf: Initialize CFLAGS before including Makefile.include bpftool: Append extra host flags bpftool: Avoid adding EXTRA_CFLAGS to HOST_CFLAGS bpftool: Pass host flags to bootstrap libbpf selftests/bpf: correct CONFIG_PPC64 macro name in comment ...

Tue, 02 Jun 2026 16:47:10 +0200

bpftool: Pass host flags to bootstrap libbpfbpftool builds a bootstrap libbpf with HOSTCC, but the libbpf submake canstill inherit target build flags through CFLAGS. This can break crossbuilds when host objects are compiled with target-only options.Since HOST_CFLAGS contains warning options that are not suitable forbuilding libbpf, use LIBBPF_BOOTSTRAP_CFLAGS with the warning optionsremoved to build the bootstrap libbpf. Clear EXTRA_CFLAGS so targetextra flags are not mixed into the host bootstrap libbpf build.Signed-off-by: Leo Yan Acked-by: Quentin Monnet Link: https://lore.kernel.org/r/20260602-tools_build_fix_zero_init_bpf_only-v2-1-c76e5250ea1c@arm.comSigned-off-by: Alexei Starovoitov List of files: /linux/tools/bpf/bpftool/Makefile

231fc9bc27fd03db171cab4e75116923250af7a7 - bpftool: Restrict feature tests during bootstrap compilation

Sun, 31 May 2026 03:07:50 +0200

bpftool: Restrict feature tests during bootstrap compilationWhen the perf build executes 'make -C ../bpf/bpftool bootstrap', bpftool'sMakefile unconditionally evaluated feature checks for llvm, libcap, libbfd,and disassembler libraries because the bootstrap target was not exempted.Since the bootstrap bpftool strictly compiles minimal AST parsing and Ccode generation logic without linking LLVM or disassembler libraries, thesefeature check sub-makes are completely redundant.Exempt the bootstrap target from non-essential feature tests to eliminateunneeded sub-make fork overhead during Kbuild startup.Tested-by: James Clark Assisted-by: Gemini:gemini-3.1-pro-previewSigned-off-by: Ian Rogers Acked-by: Quentin Monnet Link: https://lore.kernel.org/r/20260531010750.525160-1-irogers@google.comSigned-off-by: Alexei Starovoitov List of files: /linux/tools/bpf/bpftool/Makefile
