Android cofiguring problem

[GoogleCodeExporter]

Hi,all
We are tring to port USB wifi vt6656 to rowboat Android,we can use 
wireless tools(which contain iwconfig,iwlist,etc.) configuring wifi 
successfully,by using this way we can connect the internet 
successfully.However,when we tried to use Android UI(wifi setting) to 
configure it,it can find ap signal,but just a second later,the system 
crashed,the logcat message shows below:

Have more or less the same issue with a rt2870usb.
Crash occurs either when android-UI tryes to connect to a AP or tries to unload 
the
module.
I think it is either the way that android talks to the module that isn't 
completly
implemented in the driver or something in the tcp_v4 itself for our platform.

Kernel panic - not syncing: Fatal exception in interrupt

Original comment by rough...@gmail.com on 18 May 2010 at 1:03

[GoogleCodeExporter]

I did manage to get the kernel panic to go away.
What I did was copy the function tcp_v4_nuke_addr from a newer kernel. I don't 
like
it but now it dosn't panic out.
I did also set Wi-Fi sleep policy to "Never" in advanced for wifi, this might 
have
had something to do with it but without the updated function it would panic 
anyhow.

changes in kernel/net/ipv4/tcp_ipv4.c
Commented out the existing tcp_v4_nuke_addr()
and added:
void tcp_v4_nuke_addr(__u32 saddr)
{
    unsigned int bucket;

    for (bucket = 0; bucket < tcp_hashinfo.ehash_size; bucket++) {
        struct hlist_nulls_node *node;
        struct sock *sk;
        spinlock_t *lock = inet_ehash_lockp(&tcp_hashinfo, bucket);

restart:
        spin_lock_bh(lock);
        sk_nulls_for_each(sk, node, &tcp_hashinfo.ehash[bucket].chain) {
            struct inet_sock *inet = inet_sk(sk);

            if (inet->rcv_saddr != saddr)
                continue;
            if (sysctl_ip_dynaddr && sk->sk_state == TCP_SYN_SENT)
                continue;
            if (sock_flag(sk, SOCK_DEAD))
                continue;

            sock_hold(sk);
            spin_unlock_bh(lock);

            local_bh_disable();
            bh_lock_sock(sk);
            sk->sk_err = ETIMEDOUT;
            sk->sk_error_report(sk);

            goto restart;
        }
        spin_unlock_bh(lock);
    }
}
----------------------

I do really feel that this is not a solution but just a fix to keep the kernel 
from
panicing.

Hi,everyone,I also want to port usb wifi  driver to Rowboat Androd on 
beagleboard and 
use Android UI to get connet to Internet,but I have no ideal on how to do 
it.Can anyone 
give me some ideal?My wifi modules is rt2870.

Thanks,roughack.The Web page that you gave is helpfull for me.But I have a 
question 
about the Web page.Can the patch(According to the web page you gave,it make 
driver 
work with Android custom wpa_supplicant commands and SIOCSIWPRIV ioctl) gave by 
the 
Web page be used for rt2870 or other wifi modules?

I'm using the same chip (rt2870) and linuxconsultings custom wext-driver 
(awext), it 
works but it is not stable.
Awext should as far as i understand work for most wifi-drivers.

The awext thing is because some defines is missing in some wpa-files where they 
define up a list of supported drivers.

The dhcp thing is probably a folder issue.
Check if /data/misc/dhcp exists and that dhcpcd can write in it, I just chmoded 
it to 
777, had to create it thou.

If it doesn't work try starting dhcpcd with the command "dhcpcd ra0" and look 
at what 
it says. You might have to do it while Android tries to connect to your AP so 
that 
wpa_supplicant have associated the wifi driver to the right ssid.
It could also be that you forgot to add "service dhcpcd...." in your init.rc 
and then 
wpa cant find it.
I can tell you that after you get dhcpcd to work it should work, but don't 
expect it 
to work flawlessly, might need to upgrade to a 2.6.32 kernel and change to the 
rt2x00 
driver from serialmonkey for that. I haven't done that myself because I have 
some 
more important devices that gives me more headaches in the .32 kernel than it 
does in  
the .29.

I saw another thing in your log.

--> Error 2 opening /etc/Wireless/RT2870STA/RT2870STA.dat
The driver wants that file, if you compiled the driver from ralinktech 
(2.3.0.0) you 
should have it somewhere in there. don't even think you need to compile the 
source to 
get it.
If it is already there make sure the driver can read it.
