By default libtirpc will be checked +for and if available used. Otherwise, configure will fall back to using +the xdr implementation provided by libc if available. The options +--with-tirpc/--without-tirpc can be used to disable this checking. + +In addition, the xdr_control() function has been simplied to only +handle ZFSs specific use case. + +Original-patch-by: stf <s@ctrlc.hu> +Original-patch-by: Richard Yao <ryao@gentoo.org> +Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> +Signed-off-by: Signed-off-by: Carlo Landmeter <clandmeter@gmail.com> +Closes #2254 +Closes #4559 +--- + config/user-libtirpc.m4 | 30 ++++++++++++++ + config/user.m4 | 1 + + lib/libnvpair/Makefile.am | 6 +-- + lib/libnvpair/nvpair_alloc_system.c | 1 + + lib/libspl/Makefile.am | 1 - + lib/libspl/include/rpc/Makefile.am | 1 - + lib/libspl/include/rpc/types.h | 32 --------------- + lib/libspl/include/rpc/xdr.h | 43 ++++++++++++-------- + lib/libspl/xdr.c | 78 ------------------------------------- + 9 files changed, 61 insertions(+), 132 deletions(-) + create mode 100644 config/user-libtirpc.m4 + delete mode 100644 lib/libspl/include/rpc/types.h + delete mode 100644 lib/libspl/xdr.c + +diff --git a/config/user-libtirpc.m4 b/config/user-libtirpc.m4 +new file mode 100644 +index 0000000..5f92906 +--- /dev/null ++++ b/config/user-libtirpc.m4 +@@ -0,0 +1,30 @@ ++dnl # ++dnl # Check for libtirpc - may be needed for xdr functionality ++dnl # ++AC_DEFUN([ZFS_AC_CONFIG_USER_LIBTIRPC], [ ++ AC_ARG_WITH([tirpc], ++ [AS_HELP_STRING([--with-tirpc], ++ [use tirpc for xdr encoding @<:@default=check@:>@])], ++ [], ++ [with_tirpc=check]) ++ ++ LIBTIRPC= ++ LIBTIRPC_CFLAGS= ++ ++ AS_IF([test "x$with_tirpc" != xno], ++ [AC_CHECK_LIB([tirpc], [xdrmem_create], ++ [AC_SUBST([LIBTIRPC], [-ltirpc]) ++ AC_SUBST([LIBTIRPC_CFLAGS], [-I/usr/include/tirpc]) ++ AC_DEFINE([HAVE_LIBTIRPC], [1], [Define if you have libtirpc]) ++ ], ++ [if test "x$with_tirpc" != xcheck;
