This is an implementation which doesn't have undefined behavior
problems. It casts correctly that calculations are don in the correct

This prevents the following compile error that may happens if "system/filesys.h"
is included before "system/capability.h" on Ubuntu 16.04:
[1802/4407] Compiling source3/lib/system.c
In file included from ../../lib/replace/system/filesys.h:112:0,
from ../../source3/include/vfs.h:29,

/usr/include/x86_64-linux-gnu/sys/xattr.h:32:3: error: expected identifier before numeric constant
XATTR_CREATE = 1, /* set value, fail if attr already exists. */
^
The above error is from compiling a source tree which includes a change that
adds an include "system/filesys.h" to the top of "source3/include/vfs.h".
"source3/lib/system.c" has the following includes:
#include "includes.h"
#include "system/syslog.h"
#include "system/capability.h"
#include "system/passwd.h"
#include "system/filesys.h"
#include "../lib/util/setid.h"
The first include of "includes.h" pulls in "vfs.h" which will pull in
"system/filesys.h" with the mentioned change. "system/filesys.h" pulls in
<attr/xattr.h> which has this define
#define XATTR_CREATE 0x1
Later in "source3/lib/system.c" "system/capability.h" is included which includes
<sys/xattr.h> on Ubuntu 16.04 (not in later versions of glibc). This defines the
XATTR_* values as an enum:
enum {
XATTR_CREATE = 1, /* set value, fail if attr already exists. */
XATTR_REPLACE = 2 /* set value, fail if attr does not exist. */
};
The previous define of XATTR_CREATE as 1 makes this
enum {
1 = 1, /* set value, fail if attr already exists. */
2 = 2 /* set value, fail if attr does not exist. */
};
which is invalid C. The compiler error diagnostic is a bit confusing, as it
prints the original enum from the include file.

An NDR pull of a function will fill in either the in. or out.
elements of this structure, but never both.
However, some structures have size_is() in the out. that reference
the in. elements. This is the reason for the --context-file option
in ndrdump.
We have a special handler in the fuzzing case embedded in the
pidl-generated output to cope with this, by filling in pointers
for elements declared [ref,in] but it relies on the in-side
(at least) of the buffer being zeroed.
So zero the buffer before we start. Sadly this means things
like valgrind can not find a use of uninitialised data, but that
is a price we have to pay.
