The main changes are: 1) Add a new BPF netfilter program type and minimal support to hook BPF programs to netfilter hooks such as prerouting or forward, from Florian Westphal. 2) Fix race between btf_put and btf_idr walk which caused a deadlock, from Alexei Starovoitov. 3) Second big batch to migrate test_verifier unit tests into test_progs for ease of readability and debugging, from Eduard Zingerman. 4) Add support for refcounted local kptrs to the verifier for allowing shared ownership, useful for adding a node to both the BPF list and rbtree, from Dave Marchevsky. 5) Migrate bpf_for(), bpf_for_each() and bpf_repeat() macros from BPF selftests into libbpf-provided bpf_helpers.h header and improve kfunc handling, from Andrii Nakryiko. 6) Support 64-bit pointers to kfuncs needed for archs like s390x, from Ilya Leoshkevich. 7) Support BPF progs under getsockopt with a NULL optval, from Stanislav Fomichev. 8) Improve verifier u32 scalar equality checking in order to enable LLVM transformations which earlier had to be disabled specifically for BPF backend, from Yonghong Song. 9) Extend bpftool's struct_ops object loading to support links, from Kui-Feng Lee. 10) Add xsk selftest follow-up fixes for hugepage allocated umem, from Magnus Karlsson. 11) Support BPF redirects from tc BPF to ifb devices, from Daniel Borkmann. 12) Add BPF support for integer type when accessing variable length arrays, from Feng Zhou. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (71 commits) selftests/bpf: verifier/value_ptr_arith converted to inline assembly selftests/bpf: verifier/value_illegal_alu converted to inline assembly selftests/bpf: verifier/unpriv converted to inline assembly selftests/bpf: verifier/subreg converted to inline assembly selftests/bpf: verifier/spin_lock converted to inline assembly selftests/bpf: verifier/sock converted to inline assembly selftests/bpf: verifier/search_pruning converted to inline assembly selftests/bpf: verifier/runtime_jit converted to inline assembly selftests/bpf: verifier/regalloc converted to inline assembly selftests/bpf: verifier/ref_tracking converted to inline assembly selftests/bpf: verifier/map_ptr_mixing converted to inline assembly selftests/bpf: verifier/map_in_map converted to inline assembly selftests/bpf: verifier/lwt converted to inline assembly selftests/bpf: verifier/loops1 converted to inline assembly selftests/bpf: verifier/jeq_infer_not_null converted to inline assembly selftests/bpf: verifier/direct_packet_access converted to inline assembly selftests/bpf: verifier/d_path converted to inline assembly selftests/bpf: verifier/ctx converted to inline assembly selftests/bpf: verifier/btf_ctx_access converted to inline assembly selftests/bpf: verifier/bpf_get_stack converted to inline assembly ... ==================== Link: https://lore.kernel.org/r/20230421211035.9111-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
