This bug is awaiting verification that the linux-xilinx- zynqmp/5.15.0-1025.29 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-done-jammy-linux-xilinx-zynqmp'. If the problem still exists, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-failed-jammy-linux-xilinx-zynqmp'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The following is extracted from the commit message: The problem is the new offsetof() does not play nice with static asserts. Given that the context is a static assert (and CO-RE relocation is not needed at compile time), offsetof() usage can be replaced by restoring the original offsetof() definition as __builtin_offsetof(). [Test Plan] Build bpf selftest in tools/testing/selftests with the following command: make headers; make -C tools/testing/selftests TARGETS=bpf SKIP_TARGETS= \ clean all KDIR=/usr/src/linux-headers-5.15.0-85-generic/ The build can finish successfully with patched kernel source code. [Where problems could occur] Fix limited to testing tool, if this fix is incorrect the bpf selftest build will remain broken. == Original bug report == Issue found with Jammy 5.15.0-85.95 in cycle 2023.09.04 This issue does not exist with 5.15.0-83.92 in cycle 2023.08.07 (-84 is a security cycle, in which the ubuntu_bpf test was not triggered there) Test build failed with: CLNG-BPF [test_maps] test_btf_map_in_map.o CLNG-BPF [test_maps] test_btf_newkv.o CLNG-BPF [test_maps] test_btf_nokv.o CLNG-BPF [test_maps] test_btf_skc_cls_ingress.o CLNG-BPF [test_maps] test_cgroup_link.o CLNG-BPF [test_maps] test_check_mtu.o CLNG-BPF [test_maps] test_cls_redirect.o make[1]: Leaving directory '/home/ubuntu/autotest/client/tmp/ubuntu_bpf/src/linux/tools/testing/selftests/bpf' make: Leaving directory '/home/ubuntu/autotest/client/tmp/ubuntu_bpf/src/linux/tools/testing/selftests' stderr: Warning: Kernel ABI header at 'tools/include/uapi/linux/bpf.h' differs from latest version at 'include/uapi/linux/bpf.h' Warning: Kernel ABI header at 'tools/include/uapi/linux/netlink.h' differs from latest version at 'include/uapi/linux/netlink.h' Warning: Kernel ABI header at 'tools/include/uapi/linux/if_link.h' differs from latest version at 'include/uapi/linux/if_link.h' progs/test_cls_redirect.c:90:2: error: static_assert expression is not an integral constant expression sizeof(flow_ports_t) != ^~~~~~~~~~~~~~~~~~~~~~~ progs/test_cls_redirect.c:91:3: note: cast that performs the conversions of a reinterpret_cast is not allowed in a constant expression offsetofend(struct bpf_sock_tuple, ipv4.dport) - ^ progs/test_cls_redirect.c:32:3: note: expanded from macro 'offsetofend' (offsetof(TYPE, MEMBER) + sizeof((((TYPE *)0)->MEMBER))) ^ /home/ubuntu/autotest/client/tmp/ubuntu_bpf/src/linux/tools/testing/selftests/bpf/tools/include/bpf/bpf_helpers.h:81:33: note: expanded from macro 'offsetof' #define offsetof(type, member) ((unsigned long)&((type *)0)->member) ^ progs/test_cls_redirect.c:95:2: error: static_assert expression is not an integral constant expression sizeof(flow_ports_t) != ^~~~~~~~~~~~~~~~~~~~~~~ progs/test_cls_redirect.c:96:3: note: cast that performs the conversions of a reinterpret_cast is not allowed in a constant expression offsetofend(struct bpf_sock_tuple, ipv6.dport) - ^ progs/test_cls_redirect.c:32:3: note: expanded from macro 'offsetofend' (offsetof(TYPE, MEMBER) + sizeof((((TYPE *)0)->MEMBER))) ^ /home/ubuntu/autotest/client/tmp/ubuntu_bpf/src/linux/tools/testing/selftests/bpf/tools/include/bpf/bpf_helpers.h:81:33: note: expanded from macro 'offsetof' #define offsetof(type, member) ((unsigned long)&((type *)0)->member) ^ 2 errors generated. make[1]: *** [Makefile:470: /home/ubuntu/autotest/client/tmp/ubuntu_bpf/src/linux/tools/testing/selftests/bpf/test_cls_redirect.o] Error 1 make: *** [Makefile:171: all] Error 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/2035181/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
