This latest version of the patch (attached as endian10.patch.gz) endianizes a little more frame data; transmitted deauthentication reason code, received CFP values from beacons and probe responses, and received ATIM window, beacon period, and capability info when in ad hoc mode. I doubt these are sufficient to get us past the authentication timeout problem, but they are needed for correct functioning on a big endian machine.


Your patch resulted in some warnings:

CC [M] /usr/src/source/rt2570/Module/sanity.o
/usr/src/source/rt2570/Module/sanity.c: In function âonAndProbeRspSanityâ:

CC [M] /usr/src/source/rt2570/Module/rtusb_data.o

Attached is the log.

Best regards, Adam.

Hi asjo,

Wrt. the warnings: if you change lines 607, 608 of sanity.c to read:
Code:
CfParm->CfpMaxDuration = le16_to_cpup((PUSHORT)&eid_ptr->Octet[2]);
CfParm->CfpDurRemaining = le16_to_cpup((PUSHORT)&eid_ptr->Octet[4]);
do they go away? (I can't seem to get le16... etc. to actually compile on my machine. At any rate, I don't get any warning messages.)

This thing looks for all the world like it should work. Is your AP really set up to accept open authentication and no encryption? Does your Airport currently connect successfully to this AP (00:0f:66:51:c7:15)? If so, is it configured the same as your Asus WL-167g?

I overlooked this on your Dec 10 post:
Quote:
I tried pinging the ip-address, and got answers. So I ssh'ed to it, ...

That shouldn't have worked. Now I'm really confused. What did ping say?

This is turning into quite a siege, I know, but thanks,

Yes, that removed the warning messages.

My accesspoint is set up to no encryption and mac-address filtering.

I used the Asus-card with an i386-machine previously against the same accesspoint - no change in its configuration.

The Airport card works against the access point with no encryption (I use that to access the machine).

The configurations are identical except for the IP-addresses.

I think I was a little too quick there, sorry. I think the replies I got was probably through/due to the other interface - after your next patch I tried closing down the Airport-card and ping to the rt2570-card stopped getting replies.

(The Cube is headless, so I haven't tried closing networking completely off and then turning on the rt2570).

Let me know what you think I should try.

Best regards, Adam.

Hi asjo,

It looks like I may have endianized a bridge too far (cleverly, so as not to be detected.)

I started to wonder why there were all these "flase alarm" messages in the log. Also I noticed that not only was there no response to authentication request frames, there was no response to probe requests, either.

It looks like what was happening was that the BBP tuning parameters read from EEPROM were screwed up enough (because of conflicting byte flipping logic) that we weren't transmitting with enough power to be detected.

The latest version of the patch now treats BBP tuning parameters as a byte array (which is what it is) instead of an array of shorts - thereby sidestepping the need for byte flipping. The driver still seems to work OK on my little endian machine. Could you try it on your Cube and see what happens?

The latest version of the patch is attached as "endian11.patch.gz" and should be applied to a vanilla version of the latest CVS.

Thanks,

Could you go to line #800 of the patched version of rtusb_init.c:
Code:
le16_to_cpus(&Power.word);
comment it out, then see what happens?

Thanks,

Sure; log attached. Didn't seem to do the trick - I can't ping the IP of the rausb0 if I ifdown the eth2 (Airport).

Best regards, Adam.

Hi asjo,

Two questions:

1. Do other adapters see your RT2570 when they scan?
2. When you used it on your Pentium, was that USB 1.1 or 2.0? If the latter, is there any way you could try it on your Cube using USB 2.0?

Thanks, and Merry Christmas!

How can I test this?

I think I usually only see accesspoints when I do an "iwlist [iface] scan", not other adapters?

I guess the old Compaq PII has USB 1.1 - it is quite old - but I don't know.

The Cube has two identical USB-ports, I don't think I can choose between 1.1 and 2.0 on the Cube?

Apple lists the two USB ports as being "12 Mbps each" http://support.apple.com/specs/powermac ... _Cube.html - I guess that means 1.1 at the most.

Best regards, Adam

Hi asjo,

Nice to see you're back on the air. Hope you enjoyed your holidays.

Doesn't look like USB revision is a factor, so I think we can forget about that.

To see if this adapter is detectable, bring it up, then go to another PC in the area with a wireless adapter and do a scan. Doing this from an AP is something you need to consult the documentation for that specific AP on.

It turns out there's yet more endianization needed, which is included in the attached patch - endian12.patch.gz. Could you give that a try first and post the results here?

Thanks,

Has anyone tested this recently? I grabbed it but need to install the tools to build it still. All I need this driver for is injecting.

Hi beren,

I'd been working with asjo on this, but he appears to have clapped out on me (after only three months! go figure).

Anyway, if you're interested in taking up the cudgel on this, I've regenerated the previous version of the patch against the latest CVS and attached it as "endian13.patch.gz".

Please apply, build and run with debug enabled, then post your results here.

Thanks,

I am not totally AWAL, I have just been very busy. I tried the 12-patch, but got no debug messages in the logs, and had not the time to investigate and report.

I will try to make some time to try this latest patch.

Best regards,

Adam

I've just done a test with this patch. Attached is the logfile. Here is some output from the xterm:

I notice that Link Quality is reported as 0/100 for rausb0, while it is 14/92 for eth2 (the Apple Airport card).

Also, rausb0 does not report an Access Point, while eth2 does.

Let me know if there is something I should try / something I should check in the configuration, or otherwise.

Sorry for the very long turn-around time, this time.

Best regards, Adam.

I forgot to mention: The machine I am testing on runs mpd to play music through a USB soundcard. A while after doing the ifup rausb0 the sound dies.

I don't know if it is of significance, but now I've mentioned it.

Best regards, Adam
