Public bug reported: [Impact] * Creating SR-IOV enabled VMs in Openstack can sometimes trigger the GPF and leave system unusable
[Test Case] * Continuously spin up VFs and set MAC address with e.g. ifconfig [Fix] * The fix updates the VSI pointer passed down to i40e_set_vf_mac function() if the adapter is still in reset, preventing the GPF. [Regression Potential] * Regression potential should be low, as we're now updating the VSI using the ID stored in the VF pointer * Regressions could arise from issues in VF creation or reset, as that would corrupt the new VSI pointer * Patch was validated and tested in a production environment [Other] * Fix was introduced in v5.4-rc1, so all previous kernels are affected ** Affects: linux (Ubuntu) Importance: High Assignee: Heitor Alves de Siqueira (halves) Status: Confirmed ** Affects: linux (Ubuntu Xenial) Importance: High Assignee: Heitor Alves de Siqueira (halves) Status: Confirmed ** Affects: linux (Ubuntu Bionic) Importance: High Assignee: Heitor Alves de Siqueira (halves) Status: Confirmed ** Affects: linux (Ubuntu Disco) Importance: High Assignee: Heitor Alves de Siqueira (halves) Status: Confirmed ** Affects: linux (Ubuntu Eoan) Importance: High Assignee: Heitor Alves de Siqueira (halves) Status: Confirmed ** Affects: linux (Ubuntu Focal) Importance: High Assignee: Heitor Alves de Siqueira (halves) Status: Confirmed ** Tags: sts ** Description changed: [Impact] - * Creating SR-IOV enabled VMs in Openstack can sometimes trigger the GPF and - leave system unusable + * Creating SR-IOV enabled VMs in Openstack can sometimes trigger the GPF and leave system unusable [Test Case] * Continuously spin up VFs and set MAC address with e.g. ifconfig [Fix] - * The fix updates the VSI pointer passed down to i40e_set_vf_mac function() if - the adapter is still in reset, preventing the GPF. + * The fix updates the VSI pointer passed down to i40e_set_vf_mac function() if the adapter is still in reset, preventing the GPF.
