Hello,

i detected an overlapping data buffer at file 
"linux-2.6.29.3/drivers/staging/rt2860/sta/wpa.c"
For detection, i used the static code analysis tool cppcheck. It prints the
following message:
[linux-2.6.29.3/drivers/staging/rt2860/sta/wpa.c:1946]: (error) Overlapping
data buffer custom

Take a loop at file wpa.c at line 1946:

        sprintf(custom, "%s unicast", custom);

Here, var "custom" is used by iteself, this is dangerous!!!!

Best regards

Ettl Martin
