** Description changed: See the detailed issue here: https://www.intel.com/content/www/us/en /security-center/advisory/intel-sa-00069.html On Feb 27, 2017 Intel has revealed this security issue that when the rx buffer is full and not being processed, the buffer will hang and never reset. Recently we found this issue in 18.04.2, we have a shared port setup on BMC and host network, where bmc and host share the same nic rx queue, when the host kernel panic, the rx queue gradually become full and eventually cause DOS on BMC. I have verified the issue affects both 18.04-ga (i40e 2.1.14-k) and - 18.04-hwe (i40e 2.3.5), Intel had the driver fixed after version 2.3.6. + 18.04-hwe (i40e 2.3.5), I compile the latest i40e driver 2.7.29 and the + issue is gone. Intel should had the driver fixed after version 2.3.6. The current i40e driver needs patch.
