bpftool-native: Fix -Wdiscarded-qualifiers errors for glibc 2.42+

Backport a patch from kernel to fix the following build errors. bbpf.c: In function ‘kallsyms_cb’: | libbpf.c:8192:13: error: assignment discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] | 8192 | res = strstr(sym_name, ".llvm."); | | ^ | libbpf.c: In function ‘avail_kallsyms_cb’: | libbpf.c:11497:31: error: assignment discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] | 11497 | if (!(sym_sfx = strstr(sym_name, ".llvm."))) | | ^ | libbpf.c: In function ‘resolve_full_path’: | libbpf.c:12085:35: error: assignment discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] | 12085 | next_path = strchr(s, ':'); | | Signed-off-by: He Zhe Signed-off-by: Khem Raj

kernel-selftest: add missing sources if mm is enabled

2026-04-20T14:35:38+00:00

Some headers come from 'mm' (in the top source directory, i.e. the root of Linux's sources), as in the exampels below: Makefile:LOCAL_HDRS += $(selfdir)/mm/local_config.h $(top_srcdir)/mm/gup_test.h cow.c:#include "../../../../mm/gup_test.h" gup_longterm.c:#include "../../../../mm/gup_test.h" gup_test.c:#include hmm-tests.c:#include uffd-unit-tests.c:#include "../../../../mm/gup_test.h" Add this directory to KERNEL_SELFTEST_SRC if 'mm' PACKAGECONFIG is enabled.

kernel-selftest: fix mm selftests dependencies

2026-04-20T14:35:38+00:00

Add numa (numactl), as required by rmap, migration, and others. Add liburing, otherwise some tests would be disabled. Moreover, liburing's availability is checked in a shell script executed prior to the compilation of the individual test cases. This script, however, does not read CFLAGS. Backport a fix [1] from mainline to address this issue. [1] https://github.com/torvalds/linux/commit/7f532d19c8be76ad2fcd7ab6b0c9eb618f70966b Signed-off-by: João Marcos Costa Signed-off-by: Khem Raj

kernel-selftest: drop libhugetlbfs

2026-04-20T14:35:38+00:00

The support of libhugetlbfs was removed from mainline Linux a while ago, since v6.1 [1]. Since libhugetlbfs was the main reason to remove 'mm' selftests for some specific architectures, the respective operations should only remove bpf. Update the recipe to remove libhugetlbfs as a dependency of mm, and thus unblock this test category for some targets.

kernel-selftest: rename vm selftests to mm

2026-04-20T14:35:38+00:00

Since v6.10 [1], this category of selftests was renamed to 'mm'. Update the recipe accordingly. I left a mention to the previous name (i.e., 'vm') just in case.

libbpf: Upgrade to 1.7.0 release

2026-03-31T02:46:38+00:00

User space-side features * bpf_map__set_exclusive_program() and bpf_map__exclusive_program() APIs for exclusive map creation; * bpf_program__assoc_struct_ops() and bpf_prog_assoc_struct_ops() APIs to associate a non-struct_ops BPF program with a struct_ops map; * btf__permute() API to rearrange BTF types in-place according to a provided mapping; * BTF type lookup optimization: binary search for btf__find_by_name() and btf__find_by_name_kind(); * btf__add_btf() now accepts split BTF sources; * fsession support (SEC("fsession+") / SEC("fsession.s+")); * BPF_F_CPU and BPF_F_ALL_CPUS flags support for per-CPU map operations; * arena globals are moved to the end of the arena mmap region if kernel supports it; * support for LLVM-generated indirect jump tables (BPF ISA v4) via .jumptables ELF section and BPF_MAP_TYPE_INSN_ARRAY maps; * avoid expensive kallsyms parsing when kprobe.session target is an exact function match; * new dont_enable option in struct bpf_perf_event_opts to suppress perf event auto-enablement; BPF-side features * USDT SIB (Scale-Index-Base) addressing support; * dynptr helper signatures (bpf_dynptr_from_mem, bpf_dynptr_read, bpf_dynptr_write, bpf_dynptr_data) widened from 32-bit to 64-bit size/offset parameters; Bug fixes * As usual, a number of bug fixes included, see full commit log for details.

agent-proxy: Ensure that OE cflags are passed properly to build

rtla: add recipe for real-time linux analysis tool

2026-03-17T20:25:12+00:00

rtla source code is present in the kernel source tree at tools/tracing/rtla. There is another build option for rtla to enable bpf bindings, this was not a quick one to get working and left as a future improvement. Makefile for rtla has evolved in newer kernels (v6.9). Some fixes needed for support with older kernels. This commit was tested against 6.18 and 6.8. Also add rtla to packagegroup-meta-oe-benchmarks. Signed-off-by: Peter Bergin Signed-off-by: Khem Raj
