chroot

CHROOT(2)						     Linux Programmer's Manual							 CHROOT(2)

NAME

       chroot - change root directory

SYNOPSIS

       #include <unistd.h>

       int chroot(const char *path);

DESCRIPTION

       chroot()  changes the root directory of the calling process to that specified in path.  This directory will be used for pathnames beginning
       with /.	The root directory is inherited by all children of the calling process.

       Only a privileged process (Linux: one with the CAP_SYS_CHROOT capability) may call chroot().

       This call changes an ingredient in the pathname resolution process and does nothing else.

       This call does not change the current working directory, so that after the call '.' can be outside the tree rooted at '/'.  In  particular,
       the superuser can escape from a "chroot jail" by doing:

	   mkdir foo; chroot foo; cd ..

       This call does not close open file descriptors, and such file descriptors may allow access to files outside the chroot tree.

RETURN VALUE

       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

ERRORS

       Depending on the file system, other errors can be returned.  The more general errors are listed below:

       EACCES Search permission is denied on a component of the path prefix.  (See also path_resolution(7).)

       EFAULT path points outside your accessible address space.

       EIO    An I/O error occurred.

       ELOOP  Too many symbolic links were encountered in resolving path.

       ENAMETOOLONG
	      path is too long.

       ENOENT The file does not exist.

       ENOMEM Insufficient kernel memory was available.

       ENOTDIR
	      A component of path is not a directory.

       EPERM  The caller has insufficient privilege.

CONFORMING TO

       SVr4, 4.4BSD, SUSv2 (marked LEGACY).  This function is not part of POSIX.1-2001.

NOTES

       A child process created via fork(2) inherits its parent's root directory.  The root directory is left unchanged by execve(2).

       FreeBSD has a stronger jail() system call.
