RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Pierre Ossman 2010-08-23 08:43:42 UTC

This is a follow-up to bug 585182 where a non-local user could disable the entire networking system. That problem has been fixed, but users can still disable wifi and wwan at inappropriate times.

Relevant comment:

 Dan Williams      2010-08-20 15:31:54 EDT

Ah right; so the issue with Enable Networking *is* in fact fixed.  The problem
here is with "Enable Wireless", correct?

NM has always used properties for the Wifi/WWAN enable toggles, and
unfortunately those can't be protected with PK in the same way as method calls
can, becasue dbus-glib hides the necessary information.  There may be some
workarounds that we can use (and we've discussed them before) so I'll look into
the wifi/wwan switches more.

But WRT to actual servers, they most likely wont' be running wifi devices which
makes this somewhat less severe.

Comment 1 Pierre Ossman 2010-08-23 08:45:48 UTC

Wifi is probably rare on a server, yes, but isn't wwan typically a server kind of thing?

Comment 3 Bill Nottingham 2010-08-23 18:16:19 UTC

WRT to comment #1, no, not really. At least, I don't know of many servers that are connected to the internet via 3G dongles.

Ah. I thought wwan meant some kind of fancy schmancy fiber ring cards. Never mind then. )
