scsi: fcoe: Fix transport not deattached when fcoe_if_init() fails
In the Linux kernel, the following vulnerability has been resolved: scsi: fcoe: Fix transport not deattached when fcoe_if_init() fails fcoe_init() calls fcoe_transport_attach(&fcoe_sw_transport), but when fcoe_if_init() fails, &fcoe_sw_transport is not detached and leaves freed &fcoe_sw_transport on fcoe_transports list. This causes panic when reinserting module. BUG: unable to handle page fault for address: fffffbfff82e2213 RIP: 0010:fcoe_transport_attach+0xe1/0x230 [libfcoe] Call Trace: <TASK> do_one_initcall+0xd0/0x4e0 load_module+0x5eee/0x7210 ...
