CVE-2022-49725

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> i40e: Fix call trace in setup_tx_descriptors<br /> <br /> After PF reset and ethtool -t there was call trace in dmesg<br /> sometimes leading to panic. When there was some time, around 5<br /> seconds, between reset and test there were no errors.<br /> <br /> Problem was that pf reset calls i40e_vsi_close in prep_for_reset<br /> and ethtool -t calls i40e_vsi_close in diag_test. If there was not<br /> enough time between those commands the second i40e_vsi_close starts<br /> before previous i40e_vsi_close was done which leads to crash.<br /> <br /> Add check to diag_test if pf is in reset and don&amp;#39;t start offline<br /> tests if it is true.<br /> Add netif_info("testing failed") into unhappy path of i40e_diag_test()
