mac80211: ibss.c, missing regdom check?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hey,

while developing my IBSS HT mode, I think found a missing check:

When we want to join an IBSS, we first fire a scan. When a network is
found, then we join it.
This happens in ieee80211_sta_find_ibss when we call
ieee80211_sta_join_ibss.

But in both functions there is no check if we are allowed to do IBSS on
that channel.
Is this intended?
I could join an existing network on channel 8 with a modified crda
having the NO-IBSS flag on all 2.4GHz channels.

Alex
