[Bug 1869032] Re: Kernel oopsed and null pointer dereference while running ubuntu_kernel_selftests on Eoan Power8
The jenkins job for sru-misc has successfully completed on node modoc with 5.3.0-43 without any hang issue. (I don't have a chance to check for syslog, but since it's not hanging I guess it's fine). I've also tested the net/tls test in the selftest for 100 times on modoc with 5.3.0-43, passed with oops: for i in $(seq 1 100); do sudo ./tls; done Furthermore, I had it tested with the net test suite for 100 time, passed without oops: for i in $(seq 1 100); do echo "== cycle $i ==" | sudo tee /dev/kmsg; sudo make run_tests TARGETS=net; done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869032 Title: Kernel oopsed and null pointer dereference while running ubuntu_kernel_selftests on Eoan Power8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1869032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1869032] Re: Kernel oopsed and null pointer dereference while running ubuntu_kernel_selftests on Eoan Power8
I can finish running this test manually with autotest framework locally on this affected node modoc with 5.3.0-43: AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_kernel_selftests/control And the test suite can finish without tripping this issue. But during the test I noticed that there will be another "missing remote IOA" error in dmesg: [ 353.854103] test_bpf: Summary: 378 PASSED, 0 FAILED, [366/366 JIT'ed] [ 353.854127] test_bpf: test_skb_segment: success in skb_segment!

[Bug 1869032] Re: Kernel oopsed and null pointer dereference while running ubuntu_kernel_selftests on Eoan Power8
I can manually run the net suite in kselftest on 5.3.0-43-generic with modoc, by running the following command in Eoan tree: sudo make run_tests TARGETS=net The test can finish without tripping this issue. Also, I can see a "[ 28.249600] ipr 0001:08:00.0: 8150: Permanent IOA failure" message in boot dmesg, not sure if this means HW issue? https://www.ibm.com/support/knowledgecenter/TI0003N/p8ebk/urc_tables.htm ** Attachment added: "modoc.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1869032/+attachment/5341833/+files/modoc.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869032 Title: Kernel oopsed and null pointer dereference while running ubuntu_kernel_selftests on Eoan Power8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1869032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

A quick search with keywork "tls" in Eoan tree brought me this:
commit 299dfeeb7a216fe4dcfdd6ad0461ea93db72d389
Author: Jakub Kicinski
Date: Fri Jan 10 04:38:32 2020 -0800
net/tls: fix async operation
BugLink: https://bugs.launchpad.net/bugs/1864710
commit db885e66d268884dc72967279b7e84f522556abc upstream.
Mallesham reports the TLS with async accelerator was broken by
commit d10523d0b3d7 ("net/tls: free the record on encryption error")
because encryption can return -EINPROGRESS in such setups, which
should not be treated as an error.
The error is also present in the BPF path (likely copied from there).
Reported-by: Mallesham Jatharakonda
Fixes: d3b18ad31f93 ("tls: add bpf support to sk_msg handling")
Fixes: d10523d0b3d7 ("net/tls: free the record on encryption error")
