Title
scsi: bnx2fc: Flush destroy_work queue before calling bnx2fc_interface_put()
Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: bnx2fc: Flush destroy_work queue before calling bnx2fc_interface_put() The bnx2fc_destroy() functions are removing the interface before calling destroy_work. This results multiple WARNings from sysfs_remove_group() as the controller rport device attributes are removed too early. Replace the fcoe_port's destroy_work queue. It's not needed. The problem is easily reproducible with the following steps. Example: $ dmesg -w & $ systemctl enable --now fcoe $ fipvlan -s -c ens2f1 $ fcoeadm -d ens2f1.802 [ 583.464488] host2: libfc: Link down on port (7500a1) [ 583.472651] bnx2fc: 7500a1 - rport not created Yet!!
