Hi Linus, The following changes since commit 7abc678e308467ab60ffb8c31f4638a47ee3518c: Merge tag 'pmdomain-v6.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm (2025-07-18 12:02:17 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git tags/bpf-next-6.17 for you to fetch changes up to cd7c97f4584a93578f87ea6ff427f74e9a943cdf: Merge branch 'bpf-show-precise-rejected-function-when-attaching-to-__noreturn-and-deny-list-functions' (2025-07-28 19:39:30 -0700) ---------------------------------------------------------------- There are conflicts, since Christian rebased what should have been a stable branch: https://lore.kernel.org/all/20250623-rebel-verlust-8fcd4cdd9122@brauner/ and sent a pull request for 'vfs-6.17-rc1.bpf' instead: https://lore.kernel.org/all/20250725-vfs-bpf-a1ee4bf91435@brauner/ I explicitly warned against rebasing it: https://lore.kernel.org/all/CAADnVQ+iqMi2HEj_iH7hsx+XJAsqaMWqSDe4tzcGAnehFWA9Sw@xxxxxxxxxxxxxx/ since bpf/bpf-next trees are not rebased unlike vfs branches. The 'vfs-6.17.bpf' branch was created on June 23 in vfs.git and merged into bpf-next on June 26: Merge branch 'vfs-6.17.bpf' of https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs There were conflicts back then that were resolved during the merge of vfs-6.17.bpf into bpf-next: https://lore.kernel.org/all/CAADnVQ+pPt7Zt8gS0aW75WGrwjmcUcn3s37Ahd9bnLyzOfB=3g@xxxxxxxxxxxxxx/ Then more fixes to selftests/bpf/*cgroup_xattr* were applied on top. Due to unnecessary rebase these conflicts have to be resolved again. Please apply all new hunks from this pull request to resolve conflicts in: both modified: kernel/bpf/helpers.c both added: tools/testing/selftests/bpf/prog_tests/cgroup_xattr.c both added: tools/testing/selftests/bpf/progs/read_cgroupfs_xattr.c Other than that the changes are: - Remove usermode driver (UMD) framework (Thomas Weißschuh) - Introduce Strongly Connected Component (SCC) in the verifier to detect loops and refine register liveness (Eduard Zingerman) - Allow 'void *' cast using bpf_rdonly_cast() and corresponding '__arg_untrusted' for global function parameters (Eduard Zingerman) - Improve precision for BPF_ADD and BPF_SUB operations in the verifier (Harishankar Vishwanathan) - Teach the verifier that constant pointer to a map cannot be NULL (Ihor Solodrai) - Introduce BPF streams for error reporting of various conditions detected by BPF runtime (Kumar Kartikeya Dwivedi) - Teach the verifier to insert runtime speculation barrier (lfence on x86) to mitigate speculative execution instead of rejecting the programs (Luis Gerhorst) - Various improvements for 'veristat' (Mykyta Yatsenko) - For CONFIG_DEBUG_KERNEL config warn on internal verifier errors to improve bug detection by syzbot (Paul Chaignon) - Support BPF private stack on arm64 (Puranjay Mohan) - Introduce bpf_cgroup_read_xattr() kfunc to read xattr of cgroup's node (Song Liu) - Introduce kfuncs for read-only string opreations (Viktor Malik) - Implement show_fdinfo() for bpf_links (Tao Chen) - Reduce verifier's stack consumption (Yonghong Song) - Implement mprog API for cgroup-bpf programs (Yonghong Song) Signed-off-by: Alexei Starovoitov <ast@xxxxxxxxxx> ---------------------------------------------------------------- Al Viro (1): bpf: Get rid of redundant 3rd argument of prepare_seq_file() Alexei Starovoitov (22): Merge branch 'selftests-bpf-fix-a-few-test-failures-with-arm64-64kb-page' Merge branch 'bpf-mitigate-spectre-v1-using-barriers' Merge branch 'bpf-propagate-read-precision-marks-over-state-graph-backedges' Merge branch 'bpf-fix-a-few-test-failures-with-64k-page-size' Merge branch 'bpf-verifier-improve-precision-of-bpf_add-and-bpf_sub' Merge branch 'range-tracking-for-bpf_neg' Merge branch 'bpf-allow-void-cast-using-bpf_rdonly_cast' Merge branch 'bpf-add-kfuncs-for-read-only-string-operations' Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf after rc3 Merge branch 'vfs-6.17.bpf' of https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Merge branch 's390-bpf-describe-the-frame-using-a-struct-instead-of-constants' Merge branch 'bpf-standard-streams' Merge branch 'bpf-reduce-verifier-stack-frame-size' Merge branch 'bpf-additional-use-cases-for-untrusted-ptr_to_mem' Merge branch 'bpf-streams-fixes' Merge branch 'bpf-fix-and-test-aux-usage-after-do_check_insn' Merge branch 'bpf-arena-add-kfunc-for-reserving-arena-memory' Merge branch 'bpf-arm64-relax-constraint-in-bpf-jit-compiler' Merge branch 'a-tool-to-verify-the-bpf-memory-model' Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf after rc6 Merge branch 'bpf-improve-64bits-bounds-refinement' Merge branch 'bpf-show-precise-rejected-function-when-attaching-to-__noreturn-and-deny-list-functions' Alexis Lothoré (eBPF Foundation) (2): bpf, arm64: remove structs on stack constraint selftests/bpf: enable tracing_struct tests for arm64 Andrii Nakryiko (7): Merge branch 'bpf-implement-mprog-api-on-top-of-existing-cgroup-progs' Merge branch 'bpf-make-reg_not_null-true-for-const_ptr_to_map' Merge branch 'veristat-memory-accounting-for-bpf-programs' Merge branch 'support-array-presets-in-veristat' Merge branch 'bpf-add-bpf_dynptr_memset-kfunc' Merge branch 'move-attach_type-into-bpf_link' libbpf: start v1.7 dev cycle Anton Protopopov (1): bpf: add btf_type_is_i{32,64} helpers Blake Jones (2): libbpf: Add support for printing BTF character arrays as strings Tests for the ".emit_strings" functionality in the BTF dumper.
