Subject: [PATCH] xdrstdio_create buffers do not output encoded values on ppc
|
|
|
|
References: bsc#1126096
|
|
Patch-mainline: libtirpc-1-0-4
|
|
Git-commit: 145272c2b6d89a1c3a7de86a2cbef43880f1b61b
|
|
|
|
The cause is that the xdr_putlong uses a long to store the
|
|
converted value, then passes it to fwrite as a byte buffer.
|
|
Only the first 4 bytes are written, which is okay for a LE
|
|
system after byteswapping, but writes all zeroes on BE systems.
|
|
|
