Description core@road-star.jp 2005-06-12 21:51:43 UTC
shadow_copy_opendir() return address to shadow_copy_Dir. The readdir() and The
closedir() functions is hooked VFS shadow_copy module, then no problems.

But, seekdir(), telldir() and rewinddir() is not hooked by VFS shadow_copy
module. these function processed by default handler/function in the
smbd/vfs-wrap.c. these default handler expect address to struct DIR. but
shadow_copy_opendir() returned address to shadow_copy_Dir, not address to struct

Therefore paniced in seekdir(), telldir() and rewinddir() on The FreeBSD 5.4-STABLE.

Maybe other system (LINUX, Solaris,...) is not panic, return -1 and set   EBADF
to errno.

Hook seekdir(), telldir() and rewinddir()

shadow_copy module hook seekdir(), telldir() and rewinddir(). these function
don't use address to struct DIR.
