With latest llvm22, when building bpf selftest, I got the following info emitted by libbpf: ... libbpf: elf: skipping unrecognized data section(14) .comment libbpf: elf: skipping section(15) .note.GNU-stack (size 0) ... The reason is due to llvm patch [1]. Previously, bpf class BPFMCAsmInfo inherits class MCAsmInfo. With [1], BPFMCAsmInfo inherits class MCAsmInfoELF. Such a change added two more sections in the bpf binary, e.g. [Nr] Name Type Address Off Size ES Flg Lk Inf Al ... [23] .comment PROGBITS 0000000000000000 0035ac 00006d 01 MS 0 0 1 [24] .note.GNU-stack PROGBITS 0000000000000000 003619 000000 00 0 0 1 ... Adding the above two sections in elf section ignore list can avoid the above info dump during selftest build. [1] llvm/llvm-project@d9489fd Signed-off-by: Yonghong Song <[email protected]>
