From 214c13e380ad7636631279f426387f9c4e3c14d9 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 24 Mar 2025 19:05:48 -0400 Subject: [PATCH] SUNRPC: rpcbind should never reset the port to the value '0' If we already had a valid port number for the RPC service, then we should not allow the rpcbind client to set it to the invalid value '0'.
