nfsservctl − syscall interface to kernel nfs daemon

SYNOPSIS

#include <linux/nfsd/syscall.h>

nfsservctl(int cmd, struct nfsctl_arg *argp, union nfsctl_res *resp);

DESCRIPTION

/*
 * 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 file system. */
#define NFSCTL_UNEXPORT         4       /* unexport a file system. */
#define NFSCTL_UGIDUPDATE       5       /* update a client’s uid/gid map. */
#define NFSCTL_GETFH            6       /* get an fh (used by mountd) */

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;
