Permissions on Default Lockfile Make Running oned Under Unprivileged User Impossible
|Assignee:||Jaime Melis||% Done:|

|Target version:||Release 1.4|
By default the lockfile for oned is set to /var/lock/one when installing in system wide mode. Since /var/lock is not writable by unprivileged users, it is impossible to start oned.
Suggested fix is to create a /var/lock/one/ directory owned by the user/group set as one admin and place the lock file in this directory as /var/lock/one/one. I've attached a simple patch to affect this fix.
Moved the lock in system-wide installation mode. Fixed occi-server and econe-server scripts for system-wide installations #134

We have not been able to reproduce the bug. When installed in system-wide mode the /var/lock/one file is succesfully chown'd to the user referred to by the -u flag in the install.sh, therefore that user can start oned without any problems.

Thanks for checking into this. I took a look at install.sh from the latest RC and here's what I see for install locations:
if [ -z "$ROOT" ] ; then
Notice that there is no reference to a lock file at all.
If I grep -i "lock" i get nothing out of install.sh.
In the install.sh script I have, the CHOWN_DIRS variable is defined:
CHOWN_DIRS="$LOG_LOCATION $VAR_LOCATION $RUN_LOCATION"
So, I'm not sure if I'm overlooking something, or if there's a different install script that I'm not using.
Thanks again for your time and your help.

The version of OpenNebula I have uses /var/lock/one for the lock file. Check out line 118 of one-1.3.90/src/nebula/oned.cc:
lockfile = "/var/lock/one";
If the lock file is supposed to be under /var/run, then it would appear that oned.cc needs to be updated to reflect that.
Thanks again for your time.

You were very right. The reason why it was working for us is because in debian based distributions:
(debian) $ ls -ld /var/lock
drwxrwxrwt 3 root root 4096 2009-12-02 11:45 /var/lock
while in redhat/fedora:
(redhat/fedora) # ls -ld /var/lock
drwxrwxr-x 5 root lock 4096 Dec 2 12:46 /var/lock
So in debian based distributions the oneadmin user had permissions to write in /var/lock.
In any case we considered your suggestion to be the best option here, so we have commited the patch you attached and applied a few extra modifications for everything to be coherent.
Thank you very much for your great feedback.
