nfsd: unregister with rpcbind when deleting a transport

2025-10-19T14:37:00Z

commit 898374fdd7f06fa4c4a66e8be3135efeae6128d5 upstream. 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.

SUNRPC: Remove unused xdr functions

Remove a bunch of unused xdr_*decode* functions: The last use of xdr_decode_netobj() was removed in 2021 by: commit 7cf96b6d0104 ("lockd: Update the NLMv4 SHARE arguments decoder to use struct xdr_stream") The last use of xdr_decode_string_inplace() was removed in 2021 by: commit 3049e974a7c7 ("lockd: Update the NLMv4 FREE_ALL arguments decoder to use struct xdr_stream") The last use of xdr_stream_decode_opaque() was removed in 2024 by: commit fed8a17c61ff ("xdrgen: typedefs should use the built-in string and opaque functions") The functions xdr_stream_decode_string() and xdr_stream_decode_opaque_dup() were both added in 2018 by the commit 0e779aa70308 ("SUNRPC: Add helpers for decoding opaque and string types") but never used.

rpc_mkpipe_dentry(): saner calling conventions

2025-07-03T02:44:55Z

Instead of returning a dentry or ERR_PTR(-E...), return 0 and store dentry into pipe->dentry on success and return -E... on failure. Callers are happier that way... NOTE: dummy rpc_pipe is getting ->dentry set; we never access that, since we 1) never call rpc_unlink() for it (dentry is taken out by ->kill_sb()) 2) never call rpc_queue_upcall() for it (writing to that sucker fails; no downcalls are ever submitted, so no replies are going to arrive) IOW, having that ->dentry set (and left dangling) is harmless, if ugly; cleaner solution will take more massage.
