* mac802154: Fixes kernel oops when unloading a radio driverKoen Zandberg2016-02-231-1/+1

* mac802154: change frame_retries behaviourAlexander Aring2015-08-101-6/+3
| | | | | | | | | | | | | | | | | | | This patch changes the default minimum value of frame_retries to 0 and changes the frame_retries default value to 3 which is also 802.15.4 default. We don't use the frame_retries "-1" value as indicator for no-aret mode anymore, instead we checking on the ack request bit inside the 802.15.4 frame control field. This allows a acknowledge handling per frame. This checking is done by transceiver or inside xmit callback of driver layer. If a transceiver doesn't support ARET handling the transmit functionality ignores ack frames then, which isn't well but should not effect anything of current functionality.

* mac802154: Fix memory corruption with global deferred transmit state.Lennert Buytenhek2015-07-301-0/+2
| | | | | | | | | | | | | | | | | | | When transmitting a packet via a mac802154 driver that can sleep in its transmit function, mac802154 defers the call to the driver's transmit function to a per-device workqueue. However, mac802154 uses a single global work_struct for this, which means that if you have more than one registered mac802154 interface in the system, and you transmit on more than one of them at the same time, you'll very easily cause memory corruption. This patch moves the deferred transmit processing state from global variables to struct ieee802154_local, and this seems to fix the memory corruption issue.

* ieee802154: add several phy supported handlingAlexander Aring2015-05-191-0/+26
| | | | | | | | | | | | | | This patch adds support for phy supported handling for all other already existing handling 802.15.4 functionality. We assume now a fully 802.15.4 complaint transceiver at phy allocation. If a transceiver can support 802.15.4 default values only, then the values should be overwirtten by values the transceiver supports. If the transceiver doesn't set the according hardware flags, we assume the 802.15.4 defaults now which cannot be changed.

There is a backwards compatibility to have the identical types for both enum definitions. Also remove some inlcude issue with "linux/nl802154.h", because the export nl_policy inside this header it was always necessary to have an include of "net/rtnetlink.h" before. The reason for this is more complicated. Nevertheless we removed this now, because "linux/nl802154.h" is the depracted netlink interface.

* mac802154: add interframe spacing time handlingAlexander Aring2014-11-131-0/+17
| | | | | | | | | | | | | | | | | | | This patch adds a new interframe spacing time handling into mac802154 layer. Interframe spacing time is a time period between each transmit. This patch adds a high resolution timer into mac802154 and starts on xmit complete with corresponding interframe spacing expire time if ifs_handling is true. We make it variable because it depends if interframe spacing time is handled by transceiver or mac802154. At the timer complete function we wake the netdev queue again. This avoids new frame transmit in range of interframe spacing time. For synced driver we add no handling of interframe spacing time. This is currently a lack of support in all synced xmit drivers. I suppose it's working because the latency of workqueue which is needed to call spi_sync. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| | | | | | | | | | | | Tasklets have much less overhead than workqueues. This patch also removes the heap allocation for the worker on receiving path. Like mac80211 we should prefer use a tasklet here instead a workqueue to getting fast out of interrupt context when ieee802154_rx_irqsafe is called by driver.
