mac80211: move TKIP TX IVs to public part of key struct

2016-02-24T08:04:38+00:00

Some drivers/devices might want to set the IVs by themselves (and still let mac80211 generate MMIC). Specifically, this is needed when the device does offloading at certain times, and the driver has to make sure that the IVs of new tx frames (from the host) are synchronized with IVs that were potentially used during the offloading. Similarly to CCMP, move the TX IVs of TKIP keys to the public part of the key struct, and export a function to add the IV right into the crypto header. The public tx_pn field is defined as atomic64, so define TKIP_PN_TO_IV16/32 helper macros to convert it to iv16/32 when needed. Since the iv32 used for the p1k cache is taken directly from the frame, we can safely remove iv16/32 from being protected by tkip.txlock.

mac80211: use just spin_lock() in ieee80211_get_tkip_p2k()

2013-05-16T20:38:06+00:00

ieee80211_get_tkip_p2k() may be called with interrupts disabled, so spin_unlock_bh() isn't safe and leads to warnings. Since it's always called with BHs disabled already, just use spin_lock().

mac80211: use spin_lock_bh() for TKIP lock

2013-02-15T08:41:13+00:00

Since no driver calls the TKIP functions from interrupt context, there's no need to use spin_lock_irqsave(). Just use spin_lock_bh() (and spin_lock() in the TX path where we're in a BH or they're already disabled.) Signed-off-by: Johannes Berg

mac80211: remove TKIP debug

2012-06-22T09:26:58+00:00

The TKIP code hasn't been changed in a very long time, so it seems unlikely that anyone really has a need for the TKIP debug code. Remove it. Signed-off-by: Johannes Berg

net: mac80211: Convert printk(KERN_DEBUG to pr_debug

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker

mac80211: allow driver access to TKIP RX P1K

2011-07-15T17:38:32+00:00

When the driver wants to pre-program the TKIP RX phase 1 key, it needs to be able to obtain it for the peer's TA. Add API to allow it to generate it. The generation uses a dummy on-stack context since it doesn't know the RX queue. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: allow driver to generate P1K for IV32

2011-07-08T15:42:23+00:00

In order to support pre-populating the P1K cache in iwlwifi hardware for WoWLAN, we need to calculate the P1K for the current IV32. Allow drivers to get the P1K for any given IV32 instead of for a given packet, but keep the packet-based version around as an inline. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville
