commit 943cff67b842839f4f35364ba2db5c2d3f025d94 upstream. The intention of nfs4_session_set_rwsize() was to cap the r/wsize to the buffer sizes negotiated by the CREATE_SESSION. The initial code had a bug whereby we would not check the values negotiated by nfs_probe_fsinfo() (the assumption being that CREATE_SESSION will always negotiate buffer values that are sane w.r.t. the server's preferred r/wsizes) but would only check values set by the user in the 'mount' command. The code was changed in 4.11 to _always_ set the r/wsize, meaning that we now never use the server preferred r/wsizes. This is the regression that this patch fixes. Also rename the function to nfs4_session_limit_rwsize() in order to avoid future confusion. Fixes: 033853325fe3 (NFSv4.1 respect server's max size in CREATE_SESSION") Cc: stable@vger.kernel.org # v4.11+ Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
