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.

Fixed In Version: NetworkManager-1.37.3-1.el9, libnma-1.8.40-1.el9
Doc Type: Enhancement
Doc Text:
.NetworkManager now clearly indicates that WEP support is not available in RHEL 9 The `wpa_supplicant` packages in RHEL 9.0 and later no longer contain the deprecated and insecure Wired Equivalent Privacy (WEP) security algorithm. This enhancement updates NetworkManager to reflect these changes. For example, the `nmcli device wifi list` command now returns WEP access points at the end of the list in gray color, and connecting to a WEP-protected network returns a meaningful error message. For secure encryption, use only wifi networks with Wi-Fi Protected Access 2 (WPA2) and WPA3 authentication.

Description Vladimir Benes 2021-12-10 08:54:55 UTC

+++ This bug was initially created as a clone of Bug #2029341 +++

Folow-up of this:
https://bugzilla.redhat.com/show_bug.cgi?id=2029338
Comment 1 Till Maas 2022-02-22 12:22:09 UTC 
Current proposal:

- Given a RHEL 9 system with a WEP profile,
  when it is being activated
  then NM will log an via systemd stating that WEP is not supported anymore.
- Given a RHEL 9 system with a WEP profile,
  when it is activated via libnm/a tool like nmcli,
  then the activation will fail with a error message  stating that WEP is not supported anymore.
- Given a RHEL 9 system,
  when a user tries use nmcli or nm-applet or nm-connection editor to create a profile or change a profile to use WEP
  then there is no possibility to do this.
- Given a RHEL 9 system  with a profile using WEP
  when a user looks at it through nmcli or nm-applet
  then the profile is visible and it is visible that the profile is not supported anymore due to lack of WEP support.

Comment 4 Ana Cabral 2022-03-24 17:55:10 UTC 
This was included in network-manager-applet builds:

* network-manager-applet-1.26.0-1.el8, for RHEL 8.7

* network-manager-applet-1.26.0-1.el9, for RHEL 9.1
Comment 13 Vladimir Benes 2022-04-25 09:14:26 UTC 
moving to ITM12 as we don't have libnma patches ready.
Comment 14 Filip Pokryvka 2022-05-20 18:48:42 UTC 
Hi Lubo,

as we discussed, libnma "Connect hiden Wi-Fi" (used in gnome-control-center and nm-applet) still shows WEP options for new connections, which should be fixed. Should I mark this failedQA and ASSIGNED, or is this comment enough? Moving ITM to 14, so there is a time to land the fix.

Comment 23 Filip Pokryvka 2022-07-14 08:10:18 UTC 
We should have this covered in CI, moving to ITM 24, because of planned PTO.
Comment 24 Filip Pokryvka 2022-08-16 10:03:48 UTC 
I see WEP is not recognized by nmcli, but it is still possible to modify connection to WEP via nmtui (and nmcli will not report it as WEP connection, but key-mgmt: none). Is it intention to keep at least one way (nmtui) if someone really needs WEP? But I think wpa_supplicant is build without WEP support on RHEL9, so it makes little sense (building wpa_supp from sources would be required).
Comment 28 Filip Pokryvka 2022-09-01 06:13:23 UTC 
There is upstream fix for nmtui as well, verifying.
