| |
-stable review patch. If anyone has any objections, please let us know.
------------------
From: Andy Green <andy@warmcat.com>
patch dfe6e81deaa79c85086c0cc8d85b229e444ab97f in mainline.
ieee80211_get_radiotap_len() tries to dereference radiotap length without taking care that it is completely unaligned and get_unaligned() is required.
