<br />
wifi: mac80211: fix MLE defragmentation<br />
<br />
If either reconf or EPCS multi-link element (MLE) is contained in<br />
a non-transmitted profile, the defragmentation routine is called<br />
with a pointer to the defragmented copy, but the original elements.<br />
<br />
This is incorrect for two reasons:<br />
- if the original defragmentation was needed, it will not find the<br />
correct data<br />
- if the original frame is at a higher address, the parsing will<br />
potentially overrun the heap data (though given the layout of<br />
the buffers, only into the new defragmentation buffer, and then<br />
it has to stop and fail once that&#39;s filled with copied data.<br />
<br />
Fix it by tracking the container along with the pointer and in<br />
doing so also unify the two almost identical defragmentation<br />
routines.
