hostapd 0.6.7 is incompatible with 2.6.25 kernel

Reported by: thomas@… Owned by: developers
Priority: normal Milestone: Bugs Paradise
Component: packages Version:
Keywords: hostapd, 2.6.25, 2.6.28 Cc:


After commit 14227 or so, hostapd has been updated to 0.6.7. However, 0.6.7 includes new nl80211 functionality that will break with 2.6.25 and probably needs 2.6.28 (2.6.27 maybe, not sure).

I only changed the version number and md5sum back to 0.6.6 and wireless worked again (the socket filter patch still applies and works, meaning hostapd CPU usage is lower, but softirq usage is unchanged).

This is all tested with trunk as of yesterday evening on a brcm47xx (WRT54GL v1.1), b43 wifi.

The solution is to either update to >=2.6.27 so we are able to use a newer compat-wireless or to leave hostapd at 0.6.6 if mac80211 wireless is used.

This is what you get for using trunk ;).
The 8.09 branch is still at hostapd 0.6.6 (and probably will stay there), so this is a non-issue for 8.09, but still applies to trunk. Although I think we can expect that bcm47xx will be eventually upgraded to 2.6.27+, especially since there are already patches for 2.6.28.

Ah, okay, I only looked at trunk.

A bit more detail for anyone who is interested:

First, hostapd fails to set the country code. That is non-fatal, so I patched hostapd to ignore the failure. But then, I got "Unable to update rate sets for kernel module", and I gave up then, assuming that too many things had changed in the nl80211 interface.

  • Milestone changed from Kamikaze 8.09 to Kamikaze Bugs Paradize

8.09 is still using hostapd 0.6.6 as noted above, moving milestone.

This can be closed: 8.09 uses 0.6.6, trunk is upgraded to 2.6.28 (at least for the platform I use) where 0.6.8 is supported flawlessly.
