Lacking a system for us I was visiting IBM and taking a look. The setup looks sound, and it appears to
So far it seemed like what it reported a stack smashing so expect some mem overwrite. Unfortunately further debug was blocked by lacking some tools and more time. We wanted to check with memcheck and exp-sgcheck for potential sources with Valgrind. But Valgrind seems to still have issues on Ubuntu for s390x. IBM will report a bug for that soon after looking into it. Other than that - as usual - it is hard to debug overwrites. We might consider adding a ppa that has -fno-stack-protector set to have it break where it has the malicious access instead of getting a SIGABRT which is a bit more indirect. But then we might just build that for us once our RoCE setup is ready. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1553185 Title: PCI RoCe IB perftest Aborted (core dumped) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/perftest/+bug/1553185/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
