Title:
ubuntu_bpf_jit test failed on Bionic s390x systems
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Bionic:
In Progress
Bug description:
Not sure if this is related to bug 1751234 (error on AMD64 system is
different)
The ubuntu_bpf_jit test will fail with the following 5 test cases:
test_bpf: #292 BPF_MAXINSNS: Ctx heavy transformations FAIL to prog_create
err=-524 len=4096
test_bpf: #293 BPF_MAXINSNS: Call heavy transformations FAIL to prog_create
err=-524 len=4096
test_bpf: #298 BPF_MAXINSNS: ld_abs+get_processor_id FAIL to prog_create
err=-524 len=4096
test_bpf: #299 BPF_MAXINSNS: ld_abs+vlan_push/pop FAIL to select_runtime
err=-524
test_bpf: #300 BPF_MAXINSNS: jump around ld_abs FAIL to select_runtime
err=-524
test_bpf: Summary: 337 PASSED, 5 FAILED, [329/329 JIT'ed]
And modprobe error can be found in the report as well:
modprobe: ERROR: could not insert 'test_bpf': Invalid argument
Issue can be reproduce on both zVM and Ubuntu on LPAR s390x systems.
