Comment (by [EMAIL PROTECTED]):
I also see this error when running wpa_supplicant 0.4.7 ( started with
''-Dmadwifi'' ) along with a slightly patched version of madwifi 0.9.0.
I did a bit of code analysis and it looks to me like the case statement
inside of ''ieee80211_ioctl_setmlme()'' is incorrect.
I found that ''vap->iv_nsparams.result'' is only set in two places, the
''_setmlme'' function itself ( ''result = 0'' ), and the function
''ieee80211_sta_join1_tasklet'' which sets ''result'' to the return value
from ''ieee80211_new_state()''.
''ieee80211_new_state()'' calls ''vap->iv_newstate()'' which gets set to
''ieee80211_newstate()'', which it turns out always returns '0' as it's
return value!
There's also a function called ''_ _ieee80211_newstate()'' in the call
stack which only returns '0' as well.
So, it looks like:
{{{
if (vap->iv_nsparams.result)
}}}
really should be:
{{{
if (!vap->iv_nsparams.result)
}}}
...or since it looks like none of the code in any of the ''_newstate''
functions ever return any kind of error in the first place, maybe this
''if'' check can just be deleted?
Perhaps at some point, the code should be reviewed in order to make return
values a little more consistent ( ie. is success always '0', or is it '1'
)?
