enos's Issues

Increase ssh session timeouts

10 minutes idle session timeout is too small. We should either make this longer or configurable or both.

SSH doesn't write hostkey properly

On the first startup of ENOS on a fresh install, ${ENOS_ROOT}/etc doesn't exist. This prevents sshd from writing a new host key at startup time:

83688 [pool-2-thread-1] INFO org.apache.sshd.server.session.ServerSession - Server session created from /0:0:0:0:0:0:0:1:55816

Despite this problem, ENOS continues to operate fairly normally. On the first user login, ${ENOS_ROOT}/etc gets created. ENOS will continue using the same (unsaved) host key until ENOS is stopped and restarted.

On the second bootup, ENOS again fails to find a saved host key and generates a different one than before. This time, ${ENOS_ROOT}/etc exists, so it can save the key, and all works well after any users who logged in on the first boot clear out the first host key from their SSH known_hosts file.

Filing this minor but annoying bug so I don't forget to fix it. Should be pretty easy, just need to make sure that ${ENOS_ROOT}/etc exists before we initialize SSH.

End-user controlled OVS: Implementation and designer test

This activity covers the implementation, unit test writing, designer test, and documentation of the End-user controlled OVS feature.

Model OSCARS circuits as topology

Model any created/discovered OSCARS circuits as topology within the ENOS topology service.

OSCARS support

This epic covers discovery of OSCARS topology, provisioning of OSCARS circuits, and the inventory of OSCARS circuits as topology.

Don't put ENOS root directory under /tmp

The ENOS root directory is defined, by default, as /tmp/enos. However, on some operating systems (MacOS in particular), /tmp gets cleared on a reboot. On some other operating systems, it's common practice for /tmp to be a RAM disk for increased performance (which has a similar effect).

Losing the contents of the ENOS root directory is a Bad Thing (TM).

We should pick a better place for this.

MPVPN path computation engine

Extended existing path computation engine to handle intelligent routing of links utilized for a MPVPN instance.

Complete core MP-VPN functionality

This includes ARP/broadcast and MAC learning support, ODL integration for both OVS and Corsa switches.

OSCARS Layer 2 service logic

Add service logic into ENOS for gluing shell commands/application API into pathfinding and OSCARS provisioning operations.

SSH session crash for unprivileged user

During the login of an unprivileged user, the enos backend can sometimes generate an exception related to permissions. This doesn't happen all of the time. Back-end stack trace:

ENOS management of Linux Kernel virtual machines (KVM) and Linux containers (LXC)

Feature will utilize ProxMox VE (https://www.proxmox.com/en/proxmox-ve) to dynamically create, delete, and generally manage Linux-based containers. This feature is required for NFV support, however, before this, it'll be used to create containers for user controllers, fake hosts, etc. Also required for site management.

This task should wait until deployment of proxmox on the testbed if complete.

Peer testing: MVPN feature testing

No STDERR output when a python program fails

This is only when executing a program in non interactive mode, i.e.

SSH session hang for unprivileged user

If the first login session to enos is by an unprivileged user, the login session hangs after printing the banner and before the command-line prompt.

Don't show login banner on non-interactive ssh login

On UNIX, an sshd login prints the motd (etc.) for an interactive shell login, but not if you're invoking sshd to run a command. IIRC this functionality is implemented in the back-end sshd daemon.

enos should do something similar, so if invoke sshd to run say a python script within enos, I don't get the "Welcome to enos" banner in my script's output.

Integrate OSCARS Java Client

Package OSCARS Java Client into ENOS bundle as a new OSGi service. Add appropriate configuration support allow for provisioning of remote OSCARS instance.

Inconsistent symlink resolution

In some places related to the FileACL class, symlinks in pathnames are sometimes resolved and sometimes not. This is easy to observe on MacOS because /tmp is a symbolic link to /private/tmp. It causes some problems when trying to compare pathnames (in particular to see if a given pathname is within the ENOS root directory hierarchy or not).

Assigning to @davidhua for preliminary investigation.

MPVN CLI (slight) revamp / simplication

Complaints when pinging

The following complaints appeared on Python's stdout after setting up a two-node MP-VPN between lbl-diskpt1 and bnl-diskpt1 with these commands:

vpn create vpn1
vpn vpn1 addpop denv
vpn vpn1 addpop aofa
vpn vpn1 addsite lbl.gov
vpn vpn1 addsite bnl.gov
vpn vpn1 addhost [email protected]
vpn vpn1 addhost [email protected]

These seem to be caused by the ARP packets from lbl-diskpt1.

Make MP-VPN use epipes

For a number of reasons, we need to make the MP-VPN feature use epipes instead of pre-configured OSCARS circuits. This is primarily because OSCARS is implemented on VPLS, and contains some MAC learning and other LAN emulation features that do not interact well with the MP-VPN MAC address translation that is needed to ensure isolation between multiple VPNs.

The practical implication is VPNs running over OSCARS circuits will experience degraded connectivity (due to MAC learning timeouts) and throughput (due to flooding bandwidth limits). These problems were first seen during the SC15 demo prep and resulting troubleshooting.

This issue depends on #42.

Race condition with finding OdlMdsalImpl and OdlCorsaImpl

There can be a race condition where netshell-controller comes up before netshell-odl-mdsal and netshell-odl-corsa. If this happens, the Controller class might try to retrieve (and cache) the OdlMdsalImpl and OdlCorsaImpl singleton objects before they are created, which is bad.

There is a workaround, which is to call Controller.getInstance().reinit() to re-fetch the objects, but that's a manual hack.

It's also possible in some cases that we might not have OdlCorsalImpl if that module is never loaded.

We should try to handle this better. We should probably have all code use the getters in Controller for finding the other objects, and no downstream consumer of this (currently just client.py I think) should cache these directly. The getters might be able to cache non-null values for performance, but it'll always be correct to ask the classes for the instances.

Source files containing code that's affected by this: Controller.java, client.py.

Cannot create privileged threads after an un-privileged thread ran

Scenario to reproduce:

log as normal user
log out
log as admin or other privileged user: the thread will be unprivileged.

The problem is that Shell's threads come from a thread pool and after running for a user, it needs to be reset.

Support for end user controlled OVS

Create OVS instances for users, attach them to hardware switches. This supports OpenFlow experiments on the SDN testbed, where we don't want to give (too much) Corsa access. This task, automation, should wait until the deployment of proxmox is done or planned.

Unprivileged user cannot login

Steps to reproduce:

Start enos
Attempt to log-in as an unprivileged user with correct password.

Expected result: User will login successfully.
Actual result: enos will display a NullPointerException and the user shell will not allow any further inputs.

Possible cause:
With this addition in KernelSecurityManager (commit 82627ed)...:

public void checkExec(String cmd) {
        if (KernelThread.getCurrentKernelThread().isPrivileged()) {
            return;
        }
        throw new ExitSecurityException("Cannot execute UNIX processes");

An unprivileged user will be thrown the exception and the startup sequence cannot continue. A privileged user (such as admin) will still be able to login successfully.

Traceback as follows:

Default admin user doesn't get a default container

When we initialize the default admin user in do_authUser(), we only create a new profile for them. This was sufficient when all that was needed was an entry in the password file, but recent code changes have added quite a few other actions to do_createUser(), including creating a default container for a user, ACLs, etc.

We need to make creation of the default admin user use do_createUser() so that these other actions get done as well.
