@Fred: In comment #3 you state "this patchset have cause some error". If this patch set has introduced a bug, please report that in a new bug. However, since you moved the Ubuntu-18.04 task back to "New" at that time, I wonder if your intent was to demonstrate that those patches are *required to fix* a bug in 4.15.

1) Can you clarify the above?

2) Which kernel version created the log in Comment #3?

If not merge this aboving patchset, ubuntu 18.04.1 version will reproduce this error log, Can you backport it into ubuntu 18.04.1 update version?

git.diff.txt Edit (8.9 KiB, text/plain)

Hi Xinwei,

I get lots of conflict on cherry-pick d1a37dedcfcf ("net: hns3: fix a use after free problem in hns3_nic_maybe_stop_tx()") to bionic 4.15 Ubuntu kernel. Is there anyway to fix this?

and in bug description it says iscsi and spark test. Could you also provide how to reproduce the failure?

Hi Ike:

This two is not need. Thanks.

Based on this, the next step is to investigate backporting the two patches that directly address the subject of this bug report.

I remembered wrong patch that introduces conflicts when cherry-picking to 4.15. We still need to work on d1a37dedcfcf ("net: hns3: fix a use after free problem in hns3_nic_maybe_stop_tx()")

#13

Another iperf3 testing on eno3/4 of d06ES is passed.

https://kernel.ubuntu.com/~ikepanhc/lp1859756/submission_2020-06-11T07.45.27.697462.html#1-13-log

Next step for me is to run iperf3 test on eno1 of d061, which 10Gb/s connected.

Also run 96 threads on 10Gb/s hns3 for 5hr and no kernel error message.

@Xinwei,

Could you or your colleague run regression test on kernel debs in #11 and let me know if the backport is ok?

kernel debs are at https://kernel.ubuntu.com/~ikepanhc/lp1859756/

This bug is awaiting verification that the 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-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

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. Thank you!
