CRDA Failed to set regulatory domain

yensid · ‎04-16-2015

Hi,

I have a custom board based on the P1010RDB-PA and I have ported over to SDKv1.7. My rootfs image is based on fsl-core-image-minimal. I have added/enabled USB wireless adapter support and it is functional except for intermitten messages about setting the wireless regulatory domain. Once connected to an AP, at what seem to be random intervals, the connection is deauthenticated and then re-authenticated and associated to the AP again with messages associated to setting the country code with CRDA. Trying to manually set the country code with CRDA fails as well.

I believe I have included all of the build requirments for CRDA and wireless. I have upgraded the versions of crda & libnl:

The following has been added to the image:

wpa-supplicant v2.1

wireless-tools

linux-firmware-rtl-license

linux-firmware-rtl8192cu

linux-firmware-ralink

linux-firmware-ath9k

libgcrypt 1.5.3

libnl 3.2.25

iw 3.11

crda 3.13

python-m2crypto 0.22.3

Setting the Code with crda

root@-5020273:~# crda
COUNTRY environment variable not set.
root@-5020273:~# export COUNTRY=US
root@-5020273:~# crda

I have also attached my config file.

Any information or guidance is appreciated.

Hi Yensid,

Did you try the iw from the command line as:

iw reg set US

Do you have regulatory.bin?

Hi Lunmin,

Thanks for your reply.

Yes, I have tried iw reg set US. It does not change anything unfortunately. The regulatory.bin file is in /usr/lib/crda. The regulatory.bin file is built/supplied as part of CRDA in this case. Do I need to get it from another source?

Hi yensid,

Maybe you can try the regulatory.bin from

git:git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git

Hi Lunmin,

I added a recipe for wireless-regdb and built it into my image. I actually tried two different versions, the current version master-2015-04-06, and master-2014-11-18 since that matches the build used in CRDA. In both cases I have the original issue with messages from cfg80211 and the "Failed to set regulatory domain: -7" message from CRDA.

As a secondary, less desired approach, I build the kernel with the full db.txt database and CONFIG_CFG80211_INTERNAL_REGDB config set to use an internal regulatory database. This requried some additional chagnes to /net/wireless/reg.c as well. With these changes the regulatory domain is now set correctly when queried with iw reg get, but I still get the deauthtentication from wlan0 and messages from cfg80211 about setting the domain.

Using internal db.txt, built without crda:

root@5020273:~# iw reg get

country US: DFS-UNSET

I've recently been able to look at this issue again. I have found that the regulartory domain setting is just a side effect of the deauthentication. I've enabled debugging from wpa-supplicant and used wireshark to capture the event that causes the disconnect. I'm still at a loss as to what is causing the deauthentication (Reason: 2) from the network.

To recap I have a board modeled after the P1010RDB, and am trying to get a USB wireless adapter working. Currently the adapter connects to the network fine, however it drops the connection and reconnects automatically while it shoudl be connected. This causes our cloud application to drop out.

The setup is:

Adapter Rosewill RNWD-N1501UB USB adapter

Ralink RT5370 chipset

Linux rt2800usb driver (rt2x00)

wpa-supplicant v2.4

I've attached the wpa-supplicant debug log showing one event and a wireshark capture showing multiple events, pinging google between the events.

If anyone has some information to share it would be greatly appreciated! Even if it is just to suggest a different usb wireless adatper

Thanks.
