From 898374fdd7f06fa4c4a66e8be3135efeae6128d5 Mon Sep 17 00:00:00 2001 From: Olga Kornievskaia Date: Tue, 19 Aug 2025 14:04:02 -0400 Subject: nfsd: unregister with rpcbind when deleting a transport When a listener is added, a part of creation of transport also registers program/port with rpcbind. However, when the listener is removed, while transport goes away, rpcbind still has the entry for that port/type. When deleting the transport, unregister with rpcbind when appropriate. ---v2 created a new xpt_flag XPT_RPCB_UNREG to mark TCP and UDP transport and at xprt destroy send rpcbind unregister if flag set.
