From e9a21949b79414dda42a017855b288901c07e613 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Wed, 8 Oct 2014 09:48:36 +0300 Subject: mac80211: add extended channel switching capability if the driver supports CSA The Extended Channel Switching capability bit in the extended capabilities element must be set if the driver supports CSA on non-beaconing interfaces. Since this capability needs to be set during driver registration, the extended_capabiliities global variable needs to be moved to the local structure so that it can be modified.

Oct 2014 17:13:40 +0100 Subject: ieee802154: add valid psdu length helper This patch adds a generic valid psdu length check function helper. This is useful to check the length field after receiving. For example the at86rf231 doesn't filter invalid psdu length. Sometimes the CRC can also be correct. If we get the lqi value with an invalid frame length the kernel may crash because we dereference an invalid pointer in the receive buffer.
