NFSSERVCTL(2) Linux Programmer's Manual NFSSERVCTL(2)
nfsservctl - syscall interface to kernel nfs daemon
#include <linux/nfsd/syscall.h>
long nfsservctl(int cmd, struct nfsctl_arg *argp,
union nfsctl_res *resp);
Note: Since Linux 3.1, this system call no longer exists. It has
been replaced by a set of files in the nfsd filesystem; see nfsd(7).
/*
* These are the commands understood by nfsctl().
*/
#define NFSCTL_SVC 0 /* This is a server process. */
#define NFSCTL_ADDCLIENT 1 /* Add an NFS client. */
#define NFSCTL_DELCLIENT 2 /* Remove an NFS client. */
#define NFSCTL_EXPORT 3 /* Export a filesystem. */
#define NFSCTL_UNEXPORT 4 /* Unexport a filesystem. */
#define NFSCTL_UGIDUPDATE 5 /* Update a client's UID/GID map
(only in Linux 2.4.x and earlier). */
#define NFSCTL_GETFH 6 /* Get a file handle (used by mountd)
(only in Linux 2.4.x and earlier). */
struct nfsctl_arg {
int ca_version; /* safeguard */
union {
struct nfsctl_svc u_svc;
struct nfsctl_client u_client;
struct nfsctl_export u_export;
struct nfsctl_uidmap u_umap;
struct nfsctl_fhparm u_getfh;
unsigned int u_debug;
} u;
}
union nfsctl_res {
struct knfs_fh cr_getfh;
unsigned int cr_debug;
};
On success, zero is returned. On error, -1 is returned, and errno is
set appropriately.
This call is Linux-specific.
