root must be a super user

[vijayaragavansr]

Hi,

i built core-image-base and succesffully flashed onto SD Card and booted as root.

but i am unable to execute reboot,poweroff,shutdown commands.  

below my terminal log

root@melange:~# poweroff
poweroff: must be superuser.
root@melange:~# reboot
reboot: must be superuser.
root@melange:~# shutdown -r now
shutdown: warning: cannot open /var/run/shutdown.pid
shutdown: /dev/initctl: Permission denied
init: must be superuser.
root@melange:~#

am surprised that when i logged in as root i do not have have full permission? something wrong in the bitbake?

Hi,

Did you solve this issue?

I have the problem with you. The image works well on SD card, but when i try to make it work on NFS.

It has the issue.

root user can't do the reboot work.

If you have solved this issue, please share.

Thanks.

Can you describe a bit your current setup? Is your filesystem RO?

Do you use NFS? Other file system relevant tasks done in your setup?

Can you show output of serial console during kernel startup?

What does "id" display? Have you used a special way to boot/login?

Any changes done by yourself or used some standard image?

Is sticky bit set on these commands?

Have you checked why it can't open /var/run/shutdown.pid ?

What does "mount" show?

Hi Martin Maurer,
i have not done any changes in the image. just build core-image-minimal(bitbake core-image-minimal) and mounted over NFS . this is the settings of NFS at the server

#/home/vijay/fsl-arm-yocto-bsp/bld-x11/tmp/work/imx6ulevk-poky-linux-gnueabi/core-image-minimal/1.0-r0/rootfs *(rw,no_root_squash)

please find attached serial log file
below is the response of mount and id command
root@hello:~# mount

how to set sticky bit for those comamnds?

Hello Vijayaragavan Srinivasan,

There is a possible fix on the following thread:

i.mx6q yocto linux 3.10.17-- login as root,but get "permission denied (are you root?)" while ping 

Which is basically to change the permissions of the root user with:

chown root:root /bin/busybox.suid

Regards,

[vijayaragavansr]

Hi,

Thanks for quick reply. this is my terminal log after following the instruction given in the link.

root@melange:~# chown root:root /bin/busybox.suid
chown: /bin/busybox.suid: Operation not permitted
root@melange:~# su
initgroups: Operation not permitted

did not succeed.
