From d3c262f584dff64e6fe963acdbed0acdf165da63 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 19 Jul 2022 09:18:35 -0400 Subject: [PATCH] SUNRPC: Fix xdr_encode_bool() commit c770f31d8f580ed4b965c64f924ec1cc50e41734 upstream. I discovered that xdr_encode_bool() was returning the same address that was passed in the @p parameter. The documenting comment states that the intent is to return the address of the next buffer location, just like the other "xdr_encode_*" helpers. The result was the encoded results of NFSv3 PATHCONF operations were not formed correctly.
