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
