I put the station in 4 address mode. Expected packets arrive on the
access point, which sends replies back on the station clone
(wlan0.sta3), but none arrive on the station, only management frames.
Versions: hostapd-2.4-3.2.x86_64 from OpenSuSE "Leap" 42.1.
Kernel 4.1.38-50-default (stock kernel for 42.1).
The AP's NIC is a Ralink RT5370 (USB ID 148f:5370) (rt2800usb.ko).
There is an internal wireless NIC which is not used.
The AP system is a CompuLab fit-PC3-LP (AMD G-T40E @1.0GHz).
The station has a Qualcomm-Atheros QCA9377 (802.11-ac) Wi-fi NIC
(PCI ID 168c:0042) (driver: ath10k_pci.ko) and the kernel is
4.10.1-default from OpenSuSE "Tumbleweed". For this query it is running
NetworkManager-1.0.6-10.1.x86_64 although the same symptoms are seen
with a custom network setup script, equivalent to manual setup of
everything. wpa_supplicant command line arguments (edited):
wpa_supplicant -c wpa.conf -u -f wpa.log . The client (station) system
is an Acer Aspire E5-573G (Intel I5-5200U @2.2GHz).
My goal is to run a virtual machine on the laptop and have it bridged
onto the wired LAN (WDS) like a normal virtual machine. For testing
I am ignoring the VM, and concentrating on bridging the station.
I am using NetworkManager this time around because it's easier to boot
the machine and have a working 3 address network. I hope to use
NetworkManager in production because its GUI gives me low-hassle
agility to switch Service Sets and to turn on VPNs.
To start a test I do:
ip link set wlan0 down
iw dev wlan0 set 4addr on
ip link set wlan0 up
wpa_supplicant reconnects, taking 6 seconds, and the NetworkManager
infrastructure produces no syslog messages. (wlan0 is not in the
bridge with the VM's vnet0; that works but not with NetworkManager.)
On the AP the station bridge device, wlan0.sta3, appears and is placed
in the bridge next to AP's wlan0 itself. Other 3 address stations
continue to work. The station generates ICMP (4+6) echo requests, ARP,
Neighbor Discovery and Router Solicitation packets, all of which are seen
on its wlan0 by tcpdump. The AP's wlan0.sta3 emits those packets (and
wlan0 doesn't). The AP answers each one, plus sending multicast Router
Advertisements, all of which wlan0.sta3 gets according to tcpdump. But
none of the outgoing packets arrive on the station, neither as seen by
tcpdump nor by ping reports. (Both ends have 802.11 management frames.)
The firewall on both ends is not logging any dropped packets (except
Mirai probes and suchlike from the wild side, which are irrelevant).
When I turn off the station's firewall it doesn't help. The firewall
on the AP identifies the packets as coming from br0, or wlan0 on the
station, and in 3 address mode it accepts these packets on both ends.
I suspect I have failed to turn on something at the AP, but I can't
figure out what. Can anyone suggest a possibility?
