CGP6-423 : Failed to change the context for mount

Created: Mar 25, 2014 Updated: Feb 11, 2019

Resolved Date: Apr 11, 2014

Found In Version: 6.0

Fix Version: 6.0.0.4

Severity: Standard

Applicable for: Wind River Linux 6

Component/s: Userspace

Description

I failed to use the command mount with option -o context to override the default context of mount.

This blocked one of my training lab.

Steps to Reproduce

Launch two WRL CGL targets. One target is NFS server, another is NFS client.

In the NFS server (10.10.0.8/24), do
mkdir /sharedNFS
echo 'I am a root' > /sharedNFS/foo

echo '/sharedFs   10.10.0.2(rw,no_subtree_check)' > /etc/exports

exportfs -rv

In the NFS client (10.10.0.2/24), do
mkdir /mnt/sharedNFS
mount 10.10.0.8:/sharedFs /mnt/sharedFs -o context="system_u:object_r:user_home_t:s0"

ls -Z /mnt/sharedFs/
system_u:object_r:nfs_t:s0 foo  ---> still use the default context.
