Description Dimitar Yordanov 2012-07-09 05:32:40 EDT
Description of problem:
With"spacewalk-channel"  "redhat-rhn-proxy*" channels can be manipulated.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Sync the following channels to Satellite.
   satellite-sync -c rhel-x86_64-server-6  -c redhat-rhn-proxy-5.4-server-x86_64-6

2. Register EL6 system to Satellite.
3. On the EL6 system execute:
  #spacewalk-channel  --list
  #spacewalk-channel  -L
  Username: xxxxx
  # spacewalk-channel --add -c redhat-rhn-proxy-5.4-server-x86_64-6
  # spacewalk-channel  --list

Actual results:

Expected results:
Channel "redhat-rhn-proxy*" should be assigned to a system only if the system is a RHN-Proxy.
Command "spacewalk channel -L" should not list "redhat-rhn-proxy*" channels.

Additional info:
Possible fix  in /usr/sbin/spacewalk-channel.

        channels = get_available_channels(OPTIONS.user, OPTIONS.password)
        for chann in channels:

"spacewalk-channel" should not manipulate  rhn-proxy channels.
Comment 3 Stephen Herr 2012-07-09 11:43:04 EDT
Hmm, technically we probably should make the changes in the API methods that spacewalk-channel calls, not in spacewalk-channel itself. Although that really only helps us in the event that
1) a different client tool is calling the same API methods.
2) a user who is does not have write access to the Satellite code is attempting to hack the system.

I find those two situations to be unlikely, so the proposed patch is probably fine.
Comment 4 Jan Pazdziora 2012-07-27 09:47:04 EDT
I believe we have to start with the API side -- if the redhat-rhn-proxy* channel subscription should not be allowed, it has to be disabled in the API first. Only then we can start polishing the "list" operation of spacewalk-channel.
Comment 6 Michael Mráka 2012-07-31 06:04:33 EDT
API fix has been committed to spacewalk master as
commit 6812a5aa43f7a6cebbf46d0057ee4d85a5ae072d
    838502 - block subscription to satellite and proxy channels
    they need to be activated properly

Comment 13 Jan Pazdziora 2012-08-15 08:01:45 EDT
What does

rpm -qf /usr/sbin/spacewalk-channel

Comment 15 Jan Pazdziora 2012-08-15 08:19:53 EDT
Moving back ON_QA for Michael.

Please use stock (latest) rhn-setup on the client.
