Comment (by ccpearson):
Didn't hear back from Pramod, so I assume he won't mind if I jump in here.
I reformatted his patch per the coding stds, fixed a couple bugs, and
rediffed the patch against a current trunk snapshot. I'm submitting it
again, with the following doubts:
- Only had time to test beacon and probe response mgmt frames. Didn't
regression test code for other mgmt frames (only reformatted).
- Original patch wasn't freeing the app's IE buffers pointed to by the
vap. Added code to free the buffers in ath_vap_delete() -- not certain
that's the right/best place to do that.
- Original patch didn't validate the app's input IE buffer, allowing app
to send anything, including 802.11 exploits. Added code to validate the
format of the input buffer. Going out on a limb, also added logic to
prevent the app from setting "system IEs", meaning any IEE80211_ELEMID_*
(except IEEE80211_ELEMID_VENDOR) that appears in the sources. I'm
counting on the reviewer to yank that if it seems risk/undesirable.
