Bug#602776: libc: missing syscall stubs for jail_set, jail_get, jail_remove

[Christian Spoo <c.spoo@werbecafe.de>]

Package: libc0.1
Version: 2.11.2-6
Severity: normal
File: libc

libc0.1 in its current version on squeeze doesn't export the jail-related syscalls jail_set, jail_get and jail_remove.
Manual calling via syscall() works.

Steps to reproduce:

$ cat test.c
#include <sys/param.h>
#include <sys/jail.h>

int main(void) {
  int ret = jail_remove(42);
  return 0;
}
$ gcc -o test test.c
/tmp/ccOCb7Qf.o: In function `main':
test.c:(.text+0xe): undefined reference to `jail_remove'
collect2: ld returned 1 exit status
$ cat test2.c
#define _GNU_SOURCE
#include <sys/param.h>
#include <sys/jail.h>
#include <sys/syscall.h>
#include <unistd.h>

int main(void) {
  int ret = syscall(SYS_jail_remove, 42);
  return 0;
}
$ gcc -o test2 test2.c
$
