[ Upstream commit 14caefcf9837a2be765a566005ad82cd0d2a429f ]
If you call listen() and accept() on an already connect()ed rose socket, accept() can successfully connect. This is because when the peer socket sends data to sendmsg, the skb with its own sk stored in the connected socket's sk->sk_receive_queue is connected, and rose_accept() dequeues the skb waiting in the sk->sk_receive_queue.
This creates a child socket with the sk of the parent rose socket, which can cause confusion.
Fix rose_listen() to return -EINVAL if the socket has already been successfully connected, and add lock_sock to prevent this issue.

objtool throws the following warning: arch/powerpc/kvm/booke.o: warning: objtool: kvmppc_fill_pt_regs+0x30: unannotated intra-function call
Fix the warning by setting the value of 'nip' using the _THIS_IP_ macro, without using an assembly bl/mflr sequence to save the instruction pointer.

As part of nvmet_fc_ls_create_association there is a case where nvmet_fc_alloc_target_queue fails right after a new association with an admin queue is created. In this case, no one releases the get taken in nvmet_fc_alloc_target_assoc. This fix is adding the missing put.
