Public bug reported: Issue separated from bug 1768452 The ubuntu_bpf_jit will report the following failure on Xenial s390x: * test_bpf: #250 BPF_MAXINSNS: ld_abs+vlan_push/pop FAIL to select_runtime err=-524
This test has been moved to the test_verifier test in bpf of kselftests: https://github.com/torvalds/linux/commit/93731ef086cee90af594e62874bb98ae6d6eee91 "Remove all eBPF tests involving LD_ABS/LD_IND from test_bpf.ko. Reason is that the eBPF tests from test_bpf module do not go via BPF verifier and therefore any instruction rewrites from verifier cannot take place. Therefore, move them into test_verifier which runs out of user space, so that verfier can rewrite LD_ABS/LD_IND internally in upcoming patches. It will have the same effect since runtime tests are also performed from there. This also allows to finally unexport bpf_skb_vlan_{push,pop}_proto and keep it internal to core kernel." ** Affects: ubuntu-kernel-tests Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Tags: 4.4 s390x sru-20200106 sru-20200217 sru-20200316 ubuntu-bpf-jit xenial ** Tags added: 4.4 s390x sru-20200316 ubuntu-bpf-jit ** Tags added: sru-20200106 sru-20200217 ** Tags added: xenial ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868243 Title: ld_abs+vlan_push/pop from ubuntu_bpf_jit will fail on X s390x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1868243/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
