Steve,
I tried building LDM-6.0.14 on our new FreeBSD 5.2 machine, oliver
and ran into a failure associated with an apparent change in the
/usr/include/rpc/svc.h include file:
Making `all' in directory /usr/local/ldm/ldm-6.0.14/src/protocol
c89 -c -O -I../config -I. -I../misc -I../ulog -I../protocol atofeedt.c
c89 -c -O -I../config -I. -I../misc -I../ulog -I../protocol h_clnt.c
h_clnt.c: In function `h_xprt_turn':
h_clnt.c:1211: error: structure has no member named `xp_sock'
*** Error code 1
Stop in /usr/local/ldm/ldm-6.0.14/src/protocol.
*** Error code 1
Stop in /usr/local/ldm/ldm-6.0.14/src.
*** Error code 1
Stop in /usr/local/ldm/ldm-6.0.14/src.
The same failure occurs when CC is defined as 'gcc'.
The svc.h include file on FreeBSD 5.2 defines SVCXPRT as:
/*
* Server side transport handle
*/
typedef struct __rpc_svcxprt {
int xp_fd;
u_short xp_port; /* associated port number */
const struct xp_ops {
/* receive incoming requests */
bool_t (*xp_recv)(struct __rpc_svcxprt *, struct rpc_msg *);
/* get transport status */
enum xprt_stat (*xp_stat)(struct __rpc_svcxprt *);
/* get arguments */
bool_t (*xp_getargs)(struct __rpc_svcxprt *, xdrproc_t,
void *);
/* send reply */
bool_t (*xp_reply)(struct __rpc_svcxprt *, struct rpc_msg *);
/* free mem allocated for args */
bool_t (*xp_freeargs)(struct __rpc_svcxprt *, xdrproc_t,
void *);
/* destroy this struct */
void (*xp_destroy)(struct __rpc_svcxprt *);
} *xp_ops;
int xp_addrlen; /* length of remote address */
struct sockaddr_in xp_raddr; /* remote addr. (backward ABI compat)
*/
/* XXX - fvdl stick this here for ABI backward compat reasons */
const struct xp_ops2 {
/* catch-all function */
bool_t (*xp_control)(struct __rpc_svcxprt *, const u_int,
void *);
} *xp_ops2;
char *xp_tp; /* transport provider device name */
char *xp_netid; /* network token */
struct netbuf xp_ltaddr; /* local transport address */
struct netbuf xp_rtaddr; /* remote transport address */
struct opaque_auth xp_verf; /* raw response verifier */
void *xp_p1; /* private: for use by svc ops */
void *xp_p2; /* private: for use by svc ops */
void *xp_p3; /* private: for use by svc lib */
int xp_type; /* transport type */
} SVCXPRT;
The same definition on FreeBSD 4.9 is:
/*
* Server side transport handle
*/
typedef struct __rpc_svcxprt {
int xp_sock;
u_short xp_port; /* associated port number */
struct xp_ops {
/* receive incoming requests */
bool_t (*xp_recv) __P((struct __rpc_svcxprt *,
* SUN MICROSYSTEMS, INC. SHALL struct rpc_msg *));
/* get transport status */
enum xprt_stat (*xp_stat) __P((struct __rpc_svcxprt *));
/* get arguments */
bool_t (*xp_getargs) __P((struct __rpc_svcxprt *, xdrproc_t,
* or profits or other special, caddr_t));
/* send reply */
bool_t (*xp_reply) __P((struct __rpc_svcxprt *,
* Sun Microsystems, Inc. struct rpc_msg *));
/* free mem allocated for args */
bool_t (*xp_freeargs) __P((struct __rpc_svcxprt *, xdrproc_t,
caddr_t));
/* destroy this struct */
void (*xp_destroy) __P((struct __rpc_svcxprt *));
} *xp_ops;
int xp_addrlen; /* length of remote address */
struct sockaddr_in xp_raddr; /* remote address */
struct opaque_auth xp_verf; /* raw response verifier */
caddr_t xp_p1; /* private */
caddr_t xp_p2; /* private */
} SVCXPRT;
The difference appears to be that FreeBSD 4.9 uses the name 'xp_sock'
and 5.2 uses 'xp_fd'.
Checking several different platforms, I see that SVCXPRT typically
has xp_fd defined as a structure element with a #define of xp_sock
as an xp_fd in the structure definition. Here is the code from
zero:
struct __svcxprt {
int xp_fd;
#define xp_sock xp_fd
ushort_t xp_port;
/*
* associated port number.
* Obsolete, but still used to
* specify whether rendezvouser
* or normal connection
*/
struct xp_ops *xp_ops;
int xp_addrlen; /* length of remote addr. Obsoleted */
char *xp_tp; /* transport provider device name */
char *xp_netid; /* network token */
struct netbuf xp_ltaddr; /* local transport address */
struct netbuf xp_rtaddr; /* remote transport address */
char xp_raddr[16]; /* remote address. Now obsoleted */
struct opaque_auth xp_verf; /* raw response verifier */
caddr_t xp_p1; /* private: for use by svc ops */
caddr_t xp_p2; /* private: for use by svc ops */
caddr_t xp_p3; /* private: for use by svc lib */
int xp_type; /* transport type */
/*
* callback on client death
* First parameter is the current structure,
* Second parameter :
* - FALSE for the service listener
* - TRUE for a real connected socket
*/
svc_errorhandler_t xp_closeclnt;
};
