Sorry, mixing up NM and wpa_supplicant. Fix is to 2.9. Created attachment 1721327 [details]
Upstream fix on master
Using the setup steps provided in the description I configured an ethernet/wlan slave bridge as described on RHEL-8.4.0-20201212.n.0. After bringing up the bridge I was able to connect to the AP from a separate system and had no issues with communication. Marking as verified. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Moderate: wpa_supplicant security, bug fix, and enhancement update), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHSA-2021:1686 |
Created attachment 1721325 [details] Backport of upstream fix to 1.27.3 Description of problem: When creating a bridge, and putting an Ethernet slave and a Wlan slave (which has been configured as an AP), authentication will always fail when connecting to that AP. Version-Release number of selected component (if applicable): 2.9-2 How reproducible: nmcli conn add con-name "Bridge 0" \ type bridge ifname br0 \ connection.autoconnect true \ ipv4.method "manual" \ ipv4.address "$LOCALIP/$LOCALPREFIX" \ +ipv4.routes "224.0.0.0/4" nmcli conn delete "Bridge slave 0" nmcli conn add con-name "Bridge slave 0" \ master "Bridge 0" \ type ethernet ifname eth1 nmcli conn delete "Bridge slave 1" nmcli conn add con-name "Bridge slave 1" \ master "Bridge 0" \ type wifi ifname wlan0 \ mode ap ssid "$ssid" \ 802-11-wireless.band "bg" \ 802-11-wireless-security.key-mgmt "wpa-psk" \ 802-11-wireless-security.psk "$passphrase" nmcli conn up "Bridge 0" and now try to authenticate to that AP. Steps to Reproduce: 1. Create bridge. 2. Add Ethernet and WLAN slaves (WLAN must be configured as AP). 3. Bring up bridge and try to connect to it. Actual results: Authentication fails. Expected results: Authentication should succeed. Additional info: Upstream commit is 1c58317f.
