Version 2 of the lock manager is ready to be released. Amitha
says that it passes all of the tests in the suite posted by Drew (thanks
Drew). A noteable exception to this is on SGI where some lock requests
are never even received from the remote host. Also DOS sharing is not
yet complete.
On a side note, it would appear that at least some of the problems of the
previous version were in FreeBSD's XDR library. The xdr_*_int64 routines
do not correctly do network byte order conversions. Included below is
Amitha's 'hack fix'.
====
My hack fix (this is to /usr/src/lib/libc/xdr/xdr.c) is below. A similar
fix needs to be applied to xdr_int64_t. Note that xdr_opaque takes care of
swapping the bits in the byte.
#define SWAP(a,b,t) t=a;a=b;b=t
bool_t
my_xdr_u_int64_t(xdrs, uint64_p)
register XDR *xdrs;
u_int64_t *uint64_p;
{
u_int64_t x;
unsigned char* b= &x;
unsigned char t;
switch (xdrs->x_op) {
case XDR_ENCODE:
SWAP(b[0], b[7], t);
SWAP(b[1], b[6], t);
SWAP(b[2], b[5], t);
SWAP(b[3], b[4], t);
return (xdr_opaque(xdrs, (caddr_t)uint64_p, sizeof(u_int64_t)))
;
case XDR_DECODE:
if (!xdr_opaque(xdrs, (caddr_t)&x, sizeof x)) {
return (FALSE);
}
SWAP(b[0], b[7], t);
SWAP(b[1], b[6], t);
SWAP(b[2], b[5], t);
SWAP(b[3], b[4], t);
*uint64_p = x;
return (TRUE);
case XDR_FREE:
return (TRUE);
}
return (FALSE);
}
