Linux: WL2171, WPA2 PATCH issue

Hi,

The WPA2 fix has been done on top of our latest release only which was R5 SP8.
Both this fixes has been pushed into a new release (R5 SP9).

The fix is compose of a changes to the firmware file (new one is Rev 7.3.10.0.142) and also patches on top of the wpa_supplicant.
So the changes are not to the kernel drivers, but as it doesn't seem like you are using our latest service pack I am not sure if just replacing the firmware/supplicant in your build is going to work.
So basically you need to try and take the latest firmware and supplicant from the new release and see if they work with the drivers you are now using.
If they don't you will probably have no alternative other then upgrading your product to a newer release.

Hi Eyal,

Thanks for your update ,

It would be good if you share the following details

1) could you share the delta part between Rev 6.3.10.0.136 & Rev 7.3.10.0.142
2)Re certification is required or not ?
3)Compatibility with 3.2 kernel
4) Any other LIB dependency if i cross compile for my 3.2 kernel

Moreover i tried to download the latest one from "https://git.ti.com/wl12xx/" . but failed to clone .. could you also share the download process/git setup process from ubuntu ?

Thanks & Regars

1. There is no delta description between 6.3.10.0.136 & Rev 7.3.10.0.142 as there are multiple releases in between.

You can follow the release notes of all the versions that were release in between.
For R5_SP8 that this fix is on top you can find it in:
processors.wiki.ti.com/.../WL127x_Software_Releases
gforge.ti.com/.../WL12xx_R5_SP8_Release_Notes.pdf

2. In theory re certification may be needed between any firmware upgrade but since no RF changes have been made between 6.3.10.0.136 and 6.3.10.0.142, re certification is probably not needed.

3. There is a good chance that you can just take the latest firmware (6.3.10.0.42) and the latest supplicant and stay with your current kernel/drivers. It looks like no driver API changes have been made so you may be saved from doing this driver porting work. I suggest you try it out and let's hope it works.

Hi Eyal,

Based on your input , i tried to download the latest one from "https://git.ti.com/wl12xx/" . but failed to clone ..

Hi Rafghu,

For firmware:
git://git.ti.com/wl12xx/ti-utils.git
using the "ol_R5.SP9.01" tag.
Firmware files are under:
git.ti.com/.../ol_R5.SP9.01

For wpa_supplicant:
git://git.ti.com/wl12xx/hostap.git
using the "ol_R5.SP9.01" tag.
or
git.ti.com/.../ol_R5.SP9.01

what is current the firmware version number ? Got diffrent num from your previous post ( 6.3.10.0.42/7.3.10.0.142/6.3.10.0.142 )

Tried with hostapd clone & Compile .. got the following error

Hi Rafgu,

Firmware version seems ok. it should be 7.3.10.0.142 (wilink7) or 6.3.10.0.142(wilink6).
Regarding hostapd, the commit in your log doesn't seem like the latest:
It should have been:
git.ti.com/.../ol_R5.SP9.01

which is:
git.ti.com/.../4f3adaf26ee73e58edf723db47477cca3a8477d0

Are you checking out the correct commit?
In addition, is your build script environment setup correctly? Seems like it is not finding the hostap source directory.

Hi Eyal,

For firmware , i got the clarity and am direclty replacing the firmware from 6.3.10.0.136 to 6.3.10.0.142 ..

Right now i am using the "wl12xx_build.sh" script to download. i am not sure its updated properly

From .....the "wl12xx_build.sh " ,

1) its referring ol_R5.SP8.01 .. but you are asking me use "ol_R5.SP9.01" Do i need to replace?
2) This web "linuxwireless.org/.../crda-1.1.1.tar.bz2" is not reachable ( got error like from browser...Server error - server 5.9.151.49 is unreachable at this moment.)
3) I have compiled hostapd . but its not showing any ssid name ... Is there any dependent lib also needed to update ?


#!/bin/bash
2
3
declare -A gen_tag="ol_R5.SP8.01"
4
#### R5 SP8.01
5
declare -A wl12xx_download_target="git://git.ti.com/wl12xx/wl12xx.git"




function crda ()
111
{
112
stage=$1
113
if [ x"$stage" = "xdownload" -o x"$stage" = "xall" ]
114
then
115
download "linuxwireless.org/.../crda-1.1.1.tar.bz2" "crda-1.1.1.tar.bz2"
116
download "linuxwireless.org/.../2011.04.28-regulatory.bin" "2011.04.28-regulatory.bin"

I am also working on this (wl12xx_build.sh firmware install). Seems need to chang "ol_R5.SP8.01" to "ol_R5.SP9.01" in wl12xx_build.sh, even i specified to ol_R5.SP9.01 in setup-env. Otherwise, the downloaded are still old firmware files.
