| Summary | 0001388: kernel-ml-6.6.0-rc1.el8 fails to build. | ||||
| Description | linux-6.6-rc1 was released on 2023-09-10. Building kernel-ml-6.6.0-rc1 fails. (1) libcpupower.so issue [el7, el8, and el9] RPM build errors: File not found: /home/toracat/rpmbuild..../usr/lib64/libcpupower.so.0 Looks like in 6.6, it builds libcpupower.so.1 instead of libcpupower.so.0. And if you look at the %files section of the spec file: %files section of the spec file: %files -n %{name}-tools-libs %{_libdir}/libcpupower.so.0 %{_libdir}/libcpupower.so.0.0.1 Therefore the fix is to change 'libcpupower.so.0' to 'libcpupower.so.1'. (2) perf build errors [el8] After fixing (1) above, kernel build then failed with errors like: In file included from bench/sched-seccomp-notify.c:5: bench/sched-seccomp-notify.c: In function 'user_notif_syscall': bench/sched-seccomp-notify.c:55:27: error: 'SECCOMP_RET_USER_NOTIF' undeclared (first use in this function); did you mean 'SECCOMP_RET_ERRNO'? BPF_STMT(BPF_RET|BPF_K, SECCOMP_RET_USER_NOTIF), ^~~~~~~~~~~~~~~~~~~~~~ Turns out this was a known case and reported on lkml with patches: https://lkml.org/lkml/2023/9/13/526 https://lkml.org/lkml/2023/9/13/531 I have applied those 2 patches to 6.6-rc1 and the errors were gone. (3) bpftool build error [el8] After (2) was fixed, there was a new error. /usr/lib/gcc/x86_64-redhat-linux/8/../../../../lib64/Scrt1.o: In function `_start': (.text+0x24): undefined reference to `main' /usr/bin/ld: final link failed: Invalid operation It's a linker error | ||||
| Additional Information | Problems (2) and (3) were seen in el8 only. el9 build went through with no errors. In el7, perf and bpftool are disabled. | ||||
| Tags | No tags attached. | ||||
|
|
The situation with -rc2 (2023-09-17) remained the same. |
|
|
The two patches referenced earlier : https://lkml.org/lkml/2023/9/13/526 https://lkml.org/lkml/2023/9/13/531 were submitted to mainline kernel and were merged by Linus this morning. They are expected to be in 6.6-rc4. Subject: [GIT PULL] perf tools fixes for v6.6: 1st batch From: Namhyung Kim <namhyung@kernel.org> Therefore, the perf build problem will be gone in -rc4 but the bpftool issue will persist. This linker error might be resolved by using a newer version of gcc, pretty much like in el7. |
|
|
Current plan: Assuming the 2 patches are in the next -rc release, we will just disable bpftool in el8. Users can use the distro-kernel provided bpftool. el9 should have no build problem. |
|
|
6.6-rc4 is out. As expected, the 2 patches for perf are no longer needed. |
|
|
Now closing as "resolved/fixed". |
