Unable to create second AP interface with hostapd 1.0 and rt2800pci

leos220 · 09-07-2012, 09:43 PM

Greetings fellow Linux users,
I seem to be having a slight issue attempting to create a second AP using multiple BSS on my router (note it is running a modified version of IPCop, with custom kernel). I have no problem creating the first AP, however the second BSS's interface is being automatically removed by hostapd. I've tried following the instructions on various sites, including this one: http://forums.freebsd.org/showthread.php?t=24268 (as best I can, note I am using Linux) to no avail.
So far I've tried:

Not creating the interface -> no interface created, beacon broadcast, association times out
Create the interface in managed mode with iw and adding to bridge -> deleted by hostapd, beacon broadcast, association times out
Create the interface in AP mode with iw and adding to bridge -> deleted by hostapd, beacon is broadcast, association times out.

Wanted network configuration map (The one that I'm having problems with is marked in bright red):

To shorten things up a bit rather than keep posting additional logs, hostapd always seems to run vlan_dellink(IFACE) on the second interface after it created it.

Maybe this is a bug in hostapd? Or is it something wrong with my configuration?

Any help would be greatly appreciated.

I have traced this down to an issue with rt2800pci and nl80211 (partly by running a bare-bones config with a second BSS). It seems that it will not bring the virtual interface up and errors out on creating the VAP with the following:

Code:

Could not set interface wlan0_0 flags (UP): Device or resource busy
nl80211: Remove interface ifindex=136
Failed to add BSS (BSSID=02:22:6b:a6:bb:4f)

which suggests there is some type of lock on the already running interface keeping the virtual interface from coming up.

Note: Kernel 3.5.3, libnl 3.2.11

If anybody knows of a solution to this problem, I would be grateful for your assistance. In the meantime, I'll keep on digging and post back if I find something. Any additional
information upon request.

This problem was resolved using the kernel patch found at https://patchwork.kernel.org/patch/1277291/ .

However, now I am getting another issue, I am unable to connect to the primary AP (constant deauth and reauth), however I can connect to the (secondary) BSS just fine.

Something tells me this is another kernel issue that will probably be fixed in 3.6. however if anybody knows if this could be in my configuration or in hostapd itself, please let me know, It'd be nice to get this working sooner rather than later.
