bbaf1ff0 - bpf: Replace deprecated -target with --target= for Clang

Sat, 24 Jun 2023 00:18:56 +0000

bpf: Replace deprecated -target with --target= for ClangThe -target option has been deprecated since clang 3.4 in 2013. Therefore, usethe preferred --target=bpf form instead. This also matches how we use --target=in scripts/Makefile.clang.Signed-off-by: Fangrui Song Signed-off-by: Daniel Borkmann Acked-by: Yonghong Song Acked-by: Quentin Monnet Link: https://github.com/llvm/llvm-project/commit/274b6f0c87a6a1798de0a68135afc7f95def6277Link: https://lore.kernel.org/bpf/20230624001856.1903733-1-maskray@google.com List of files: /linux-6.15/kernel/bpf/preload/iterators/Makefile

0f0e5f5b - bpf: iterators: Split iterators.lskel.h into little- and big- endian versions

Sat, 28 Jan 2023 00:06:43 +0000

bpf: iterators: Split iterators.lskel.h into little- and big- endian versionsiterators.lskel.h is little-endian, therefore bpf iterator is currentlybroken on big-endian systems. Introduce a big-endian version and addinstructions regarding its generation. Unfortunately bpftool'scross-endianness capabilities are limited to BTF right now, so theprocedure requires access to a big-endian machine or a configuredemulator.Signed-off-by: Ilya Leoshkevich Link: https://lore.kernel.org/r/20230128000650.1516334-25-iii@linux.ibm.comSigned-off-by: Alexei Starovoitov List of files: /linux-6.15/kernel/bpf/preload/iterators/Makefile

3848636b - bpf: iterators: Build and use lightweight bootstrap version of bpftool

Thu, 14 Jul 2022 02:46:12 +0000

bpf: iterators: Build and use lightweight bootstrap version of bpftoolkernel/bpf/preload/iterators use bpftool for vmlinux.h, skeleton, andstatic linking only. So we can use lightweight bootstrap version ofbpftool to handle these, and it will be faster.Suggested-by: Andrii Nakryiko Signed-off-by: Pu Lehui Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20220714024612.944071-4-pulehui@huawei.com List of files: /linux-6.15/kernel/bpf/preload/iterators/Makefile

d7db0a4e - bpftool: Add install-bin target to install binary only

Thu, 07 Oct 2021 19:44:38 +0000

bpftool: Add install-bin target to install binary onlyWith "make install", bpftool installs its binary and its bash completionfile. Usually, this is what we want. But a few components in the kernelrepository (namely, BPF iterators and selftests) also install bpftoollocally before using it. In such a case, bash completion is notnecessary and is just a useless build artifact.Let's add an "install-bin" target to bpftool, to offer a way to installthe binary only.Signed-off-by: Quentin Monnet Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20211007194438.34443-13-quentin@isovalent.com List of files: /linux-6.15/kernel/bpf/preload/iterators/Makefile

bpf: iterators: Install libbpf headers when buildingAPI headers from libbpf should not be accessed directly from thelibrary's source directory. Instead, they should be exported with "makeinstall_headers".

f0fdfefb - bpf: Add BPF program and map iterators as built-in BPF programs.

Wed, 19 Aug 2020 04:27:57 +0000

bpf: Add BPF program and map iterators as built-in BPF programs.The program and map iterators work similar to seq_file-s.Once the program is pinned in bpffs it can be read with "cat" toolto print human readable output. In this case about BPF programs and maps.For example:$ cat /sys/fs/bpf/progs.debug id name attached 5 dump_bpf_map bpf_iter_bpf_map 6 dump_bpf_prog bpf_iter_bpf_prog$ cat /sys/fs/bpf/maps.debug id name max_entries 3 iterator.rodata 1To avoid kernel build dependency on clang 10 separate bpf skeleton generationinto manual "make" step and instead check-in generated .skel.h into git.Unlike 'bpftool prog show' in-kernel BTF name is used (when available)to print full name of BPF program instead of 16-byte truncated name.Signed-off-by: Alexei Starovoitov Signed-off-by: Daniel Borkmann Acked-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20200819042759.51280-3-alexei.starovoitov@gmail.com List of files: /linux-6.15/kernel/bpf/preload/iterators/Makefile
