Permission change in plugin.sh script in cyborg/devstack

[Henry Sun]

I is my first time to report a bug in Openstack community and I would appreciate any of your advices or instructions.

I tried to start devstack with cyborg with the following additional configuration in local.conf:

    enable_plugin cyborg https://git.openstack.org/openstack/cyborg

However, cyborg project did not run successfully.

This might be result from the permission change to the /opt/stack/cyborg directory in file cyborg/devstack/lib/cyborg, related code of with is shown below:

    sudo chmod 0440 $CYBORG_DIR

This disallows user's permission to exec/write, and therefore prevent run_plugins() in devstack/function-common to execute the script in line 1669:

1668 if [[ -f $dir/devstack/plugin.sh ]]; then
1669 source $dir/devstack/plugin.sh $mode $phase
1670 fi

So when stack.sh exec the script "run_plugins stack extra", cyborg directory could be found by stack.sh but it won't start at all as can be seen from the following logs.

In /opt/stack/logs/stack.sh.log:

No we can deploy cyborg in devstack, and wont fond this issue.
