Thanks, Tim Kientzle, but i still need one "c code" to add to
autoconf.c, and gets a NFS file handle to my root directory. We have
the solution (diskless) with dhcp/bootp... but we do not want this
anymore, due the things that i have sad before. Thanks.
All that i need, is that c code... :)
In vfs_syscalls.c i have found this "code":
---
/*
* Get (NFS) file handle
*/
#ifndef _SYS_SYSPROTO_H_
struct getfh_args {
char *fname;
fhandle_t *fhp;
};
#endif
int
getfh(p, uap)
struct proc *p;
register struct getfh_args *uap;
{
struct nameidata nd;
fhandle_t fh;
register struct vnode *vp;
int error;
/*
* Must be super user
*/
error = suser(p);
if (error)
return (error);
NDINIT(&nd, LOOKUP, FOLLOW | LOCKLEAF, UIO_USERSPACE, uap->fname,
p);
error = namei(&nd);
if (error)
return (error);
NDFREE(&nd, NDF_ONLY_PNBUF);
vp = nd.ni_vp;
bzero(&fh, sizeof(fh));
fh.fh_fsid = vp->v_mount->mnt_stat.f_fsid;
error = VFS_VPTOFH(vp, &fh.fh_fid);
vput(vp);
if (error)
return (error);
error = copyout(&fh, uap->fhp, sizeof (fh));
return (error);
}
