Edward Adam Davis f60d38cb02 pidfs: when time ns disabled add check for ioctl ... syzbot call pidfd_ioctl() with cmd "PIDFD_GET_TIME_NAMESPACE" and disabled CONFIG_TIME_NS, since time_ns is NULL, it will make NULL ponter deref in open_namespace. Fixes: 5b08bd4085 ("pidfs: allow retrieval of namespace file descriptors") # mainline only Reported-and-tested-by: syzbot+34a0ee986f61f15da35d@syzkaller.appspotmail.com Closes: https://syzkaller.appspot.com/bug?extid=34a0ee986f61f15da35d Signed-off-by: Edward Adam Davis <eadavis@qq.com> Link: https://lore.kernel.org/r/tencent_7FAE8DB725EE0DD69236DDABDDDE195E4F07@qq.com Signed-off-by: Christian Brauner <brauner@kernel.org>		2024-07-24 10:53:12 +02:00
