+Subject: [PATCH] net: sunrpc: Fix an off by one in rpc_sockaddr2uaddr()
+Git-commit: d6f4de70f73a106986ee315d7d512539f2f3303a
+Patch-mainline: v6.9-rc1
+References: git-fixes
+
+The intent is to check if the strings' are truncated or not. So, >= should
+be used instead of >, because strlcat() and snprintf() return the length of
+the output, excluding the trailing NULL.
+
+Fixes: a02d69261134 ("SUNRPC: Provide functions for managing universal addresses")
