libbpf: Change hash_combine parameters from long to unsigned long (2024-11-16 11:01:38 -0800)
----------------------------------------------------------------
= BPF networking changes will come via net-next PR
= Several arch/x86/ and uprobe patches are also in Ingo's PR:
https://lore.kernel.org/all/Zzt5lYZGF8IOrgpB@gmail.com/
They were pulled into bpf-next via stable tag 'perf-core-for-bpf-next'.
Then Jiri's uprobe session patches were applied on top.
tip or bpf-next PRs can be pulled in any order. sha-s are the same.
= The following are the main BPF changes (there should be no conflicts):
- Add BPF uprobe session support (Jiri Olsa)
- Optimize uprobe performance (Andrii Nakryiko)
- Add bpf_fastcall support to helpers and kfuncs (Eduard Zingerman)
- Avoid calling free_htab_elem() under hash map bucket lock (Hou Tao)
- Prevent tailcall infinite loop caused by freplace (Leon Hwang)
- Mark raw_tracepoint arguments as nullable (Kumar Kartikeya Dwivedi)
- Introduce uptr support in the task local storage map (Martin KaFai Lau)
- Stringify errno log messages in libbpf (Mykyta Yatsenko)
- Add kmem_cache BPF iterator for perf's lock profiling (Namhyung Kim)
- Support BPF objects of either endianness in libbpf (Tony Ambardar)
- Add ksym to struct_ops trampoline to fix stack trace (Xu Kuohai)
- Introduce private stack for eligible BPF programs (Yonghong Song)
- Migrate samples/bpf tests to selftests/bpf test_progs (Daniel T. Lee)
- Migrate test_sock to selftests/bpf test_progs (Jordan Rife)
