Fix TX status reporting in ath9k none

Description Jaiv 2009-12-05 02:28:12 UTC 
Description of problem:

I have network card D-Link DWA-552 which uses ath9k driver. I tried hostapd trunk version as well as 0.7.0 which are working fine with F11 kernel, but with F12 kernel I immediately experienced DHCP problems and wifi clients were disconnected after about 2-5 minutes after the handshake was established (and did not reconnect afterwards). 

Version-Release number of selected component (if applicable):

Here are the kernel versions I tried with hostapd 0.7.0 and with latest git as well:

kernel-PAE-2.6.30.9-99.fc11.i686 - working
kernel-PAE-2.6.31.5-127.fc12.i686 - not working
kernel-PAE-2.6.31.6-145.fc12.i686 - not working
kernel-PAE-2.6.31.6-160.fc12.i686 - not working
kernel-PAE-2.6.32-0.65.rc8.git5.fc13.i686 - not working

How reproducible:
always

Steps to Reproduce:
1. Use F12 kernels (or later)
2.
3.
  
Actual results:
unstable wifi connection

Expected results:
stable wifi connection

Fix TX status reporting in ath9k
Comment 2 Jouni Malinen 2009-12-07 19:59:56 UTC 
The patch that I just attached here is expected to resolve the issue with ath9k not reporting the TX status correctly and as such, making hostapd not allow stations to complete association in some cases. I'm not sure whether this is related to the part of getting disconnected after 2-5 minutes, but this will hopefully handle the not being able reconnect part which is clearly visible in the debug log from hostapd here.
Comment 3 Radoslaw Kujawa 2009-12-07 23:23:50 UTC 
Hi, I can confirm that after applying this patch, it is possible to connect. However, connection is still very unstable, and does not last more than 2 minutes in my case.
Comment 4 Juergen Northe 2009-12-09 23:22:54 UTC 
I had exact the same problems before. 

But now I have to confirm, that my FC 12 with the recent compat-wireless-2009-12-08 (which includes the patch mentioned above) is working - stable @54MBit !

Hardware: Mainboard Intel Atom N270 (2.6.31.6-162.fc12.i686 -no PAE!!!)
Wireless NIC:  Sparklan WPEA-110N MINI PCI Express (AR9280) ath9k

I suppose that the usage of the PAE kernel plus the missing patch was the reason why the wireless network was unstable. If shorewall is what you're using as firewall script, do not forget to add 'dhcp' as 'options' for the 'br0' interface in /etc/shorewall/interfaces. This will help your dhcpd server to answer the requests of the clients ;-)

Well done!  Thank you very much !
Comment 5 Martin Decky 2009-12-13 12:16:21 UTC 
I can confirm all of the previous observations on my own hardware. To sum up:

1) The unmodified kernel-PAE-2.6.31.6-166.fc12.i686 (or any other kernel from Fedora 12 for that matter) breaks hostapd (the error message is "did not acknowledge association response"). All the 2.6.30 PAE kernels from Fedora 11 seem to work fine.

2) Applying the patch from comment #1 to kernel-PAE-2.6.31.6-166.fc12.i686 allows the hostapd to complete station association. However, the communication is very unstable and generally dies after 2 - 3 minutes when the association is no longer possible (no specific error message can be found in the logs).

3) Compiling compat-wireless-2.6 modules (2009-12-11) against kernel-PAE-2.6.31.6-166.fc12.i686 helps even more, but the communication is still very unstable (the data rate generally drops to 1 Mb even for devices four feet away from the ath9k; sometimes the connection dies out completely). Again, nothing much interesting in can be found in the logs.

4) The only combination which gives perfect performance and a rock-solid stability is compat-wireless-2.6 (2009-12-11) compiled against a non-PAE kernel-2.6.31.6-166.fc12.i686.


The fact that the PAE kernel somehow contributes to the problem is really strange. I have just spent several hours analysing the changes between kernel-PAE-2.6.30.9-99.fc11.i686 and kernel-PAE-2.6.31.6-166.fc12.i686, but I haven't found anything which could lead me to the root cause of the bug. Are there any kernel hackers who are willing to look into that? Many thanks.

Comment 6 Juergen Northe 2009-12-14 23:22:43 UTC 
It took me serveral hours to find out that the only working kernel is the one *without* PAE. 
Interessting is that a `tcpdump -n -v -i <wlanX>` on the server side spit out the ARP and the broadcasts requests of the client. Dhcp reqeusts where not answered by the server. I suppose its a problem within the tcp conversation / handshake / ACK.

Hmm... I can not figure out whats the different between a PAE and a non PAE kernel causing such a rude behaviour..
Comment 7 George Shearer 2009-12-28 18:53:56 UTC 
I am still experiencing this issue with the latest 2.6.31.9-174 kernel on x86_64.

hostapd: wlan0: STA 00:21:5c:39:a3:99 IEEE 802.11: did not acknowledge authentication response

Nothing but those in my hostapd log.

However if I build & install the latest compat-wireless, it seems to be fine.

seems we just have to wait for the developers/maintainers to get back from their holiday travels and push the latest fixes into the F12 kernel release.
Comment 8 Jaiv 2010-01-25 22:19:33 UTC 
I'm still experiencing this issue with latest Fedora 12 kernel-PAE-2.6.31.12-174.2.3.fc12.i686 and Hostapd 0.7.1

On the other hand kernel-PAE-2.6.30.10-105.fc11.i686 from Fedora 11 with Hostapd 0.7.1 is working fine.

It seems to be a long holiday...
Comment 9 George Shearer 2010-02-05 20:43:47 UTC 
I'm testing 2.6.32.7-37.fc12.x86_64.. So far, my clients are connecting.. If you don't see a further post from me within a few days, assume it's happy. :)
Comment 10 Juergen Northe 2010-02-05 23:34:00 UTC 
Hi George,
it sounds great. It is not a PAE kernel, isn't it? Which version of hostapd do you use - I suppose the latest one.
I read about improvements supporting wireless network cards in oncoming kernel versions (>2.6.31). So your result might be the first proof of it ;-)
Well done !
Comment 11 Jaiv 2010-02-09 23:45:22 UTC 
Hi guys,

I tried to compile below versions of compat-wireless (from http://linuxwireless.org/en/users/Download/stable/) with below kernels and hostapd 0.7.1:

- kernel-PAE-2.6.30.10-105.fc11.i686 + compat-wireless-2.6.30 - works fine

- kernel-PAE-2.6.31.12-174.2.3.fc12.i686 + compat-wireless-2.6.31-rc7 - I managed to compile with some difficulties (to resolve I copied used driver-select from 2.6.32) so in final compilation of ath9k was successful but I got into the same problem:

"IEEE 802.11: did not acknowledge authentication response"

So does not look good for me. If anybody wants me to try any other kernel and/or wireless or hostapd version please let me know.
Comment 12 George Shearer 2010-02-10 00:39:31 UTC 
Just to confirm my findings:

System: Intel Atom 330
Distribution: Fedora 12 "off the shelf" plus all updates.
Kernel: kernel-2.6.32.7-37.fc12.x86_64 (from updates-testing repo)
Application: hostapd-0.6.9-7.fc12.x86_64

19:36:37 up 4 days,  3:55,  1 user,  load average: 0.01, 0.02, 0.03

Over 4 days since I rebooted on that kernel, things are working perfectly.

Comment 14 Jaiv 2010-02-18 00:04:51 UTC 
Here is my update:

I tried to run below kernels with hostapd 0.7.1 and my ath9k card:
- kernel-PAE-2.6.31.12-174.2.3.fc12.i686 - not working
- kernel-2.6.31.12-174.2.19.fc12.i686 - not working
- kernel-2.6.31.12-174.2.19.fc12.i686 with ath9k compiled from compat-wireless-2.6.31-rc7 - working for couple of minutes, then I get lot of these:

Feb 17 23:13:09 localhost hostapd: wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: authenticated
Feb 17 23:13:09 localhost hostapd: wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: associated (aid 2)
Feb 17 23:13:12 localhost hostapd: wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: deauthenticated due to local deauth request
Feb 17 23:13:12 localhost hostapd: wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: authenticated

Feb 17 23:13:15 localhost hostapd: wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: deauthenticated due to local deauth request

In final I tried:
- kernel-2.6.32.8-58.fc12.i686 (non-PAE) which I downloaded directly from koji - seems to be working fine (even without extra compilation from linux wireless)

Please note I have to use non-PAE kernel as PAE kernels seem to have a bug affecting VIA padlock modules - I will report it in separate ticket.

So I will try to use the latest kernel and I let you know if there is any additional problem affecting hostapd or ath9k.
Comment 15 Ronald Wells 2010-04-26 15:41:00 UTC 
Any update on this?  I appear to be running into this same issue with  2.6.32.11-99.fc12.x86_64
Comment 16 Ronald Wells 2010-05-04 13:49:16 UTC 
I'm still getting a crash with hostapd and ath9k.  I've tried a bunch of different combinations of kernel and hostapd.  I've tried both PAE and Non PAE kernels with the same results.  If someone who has this working would please post more specific instructions on how exactly you got this to work I would really appreciate it!  

here are the results of lspci |grep Wire

Comment 17 John W. Linville 2010-05-04 14:57:34 UTC 
Comment 16 seems to be a duplicate of bug 587727 -- please pursue that issue there (including testing kernel-2.6.32.12-115.fc12)...thanks!

Given that other positive feedback, I'm closing this bug as CURRENTRELEASE.
