* ieee802154: add ack request default handlingAlexander Aring2015-08-10
| | | | | | | | | | | This patch introduce a new mib entry which isn't part of 802.15.4 but useful as default behaviour to set the ack request bit or not if we don't know if the ack request bit should set. This is currently used for stacks like IEEE 802.15.4 6LoWPAN.

* mac802154: change frame_retries behaviourAlexander Aring2015-08-10
| | | | | | | | | | | | | | | | | | | 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: cfg: remove test and set checksAlexander Aring2015-08-10
| | | | | | | | | | | | | | | | This patch removes several checks if a value is really changed. This makes only sense if we have another layer call e.g. calling the driver_ops which is done by callbacks like "set_channel". For MAC settings which need to be set by phy registers (if the phy supports that handling) this is set by doing an interface up currently and are not direct driver_ops calls, so we remove the checks from these configuration callbacks.

* mac802154: fix wpan mac setting while lowpan is thereAlexander Aring2015-08-10
| | | | | | | | | | | | | | | | | | | | If we currently change the mac address inside the wpan interface while we have a lowpan interface on top of the wpan interface, the mac address setting doesn't reach the lowpan interface. The effect would be that the IPv6 lowpan interface has the old SLAAC address and isn't working anymore because the lowpan interface use in internal mechanism sometimes dev->addr which is the old mac address of the wpan interface. This patch checks if a wpan interface belongs to lowpan interface, if yes then we need to check if the lowpan interface is down and change the mac address also at the lowpan interface. When the lowpan interface will be set up afterwards, it will use the correct SLAAC address which based on the updated mac address setting.

* mac802154: Fix memory corruption with global deferred transmit state.Lennert Buytenhek2015-07-30
| | | | | | | | | | | | | | | | | | | 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.

* mac802154: cfg: add suspend and resume callbacksAlexander Aring2015-07-23
| | | | | | | | | | | | | | | | | | | This patch introduces suspend and resume callbacks to mac802154. When doing suspend we calling the stop driver callback which should stop the receiving of frames. A transceiver should go into low-power mode then. Calling resume will call the start driver callback, which starts receiving again and allow to transmit frames. This was tested only with the fakelb driver and a qemu vm by doing the following commands: echo "devices" > /sys/power/pm_test echo "freeze" > /sys/power/state while doing some high traffic between two fakelb phys.

The difference between these flags are that the MAC handling flags are only handled in mac802154/HardMac layer e.g. on an interface up. The phy settings are direct netlink calls from nl802154 into the driver layer and the nl802154 need to have a chance to check if the driver supports this handling before sending to the next layer. We also check now on PHY flags while dumping and setting pib attributes. In comparing with MIB attributes the 802.15.4 gives us an default value which we assume when a transceiver implement less functionality.

| | | | | | | | | | | | | | | | | | | | This patch change the transmit power from s8 to s32. This prepares to store a mbm value instead dbm inside the transmit power variable. The old interface keep the a s8 dbm value, which should be backward compatibility when assign s8 to s32.

| * ieee802154: move validation check out of softmacAlexander Aring2015-05-19
| | | | | | | | | | | | | | | | | | This patch moves the value validation out of softmac layer. We need to be sure now that this value is accepted by the transceiver/mac802154 or "possible" hardmac drivers before calling rdev-ops.

| * mac802154: Switch to new AEAD interfaceHerbert Xu2015-05-28

| | | | | | | | | | | | | | | | | | | | | | | | | | | | All users of AEAD should include crypto/aead.h instead of include/linux/crypto.h. This patch also removes a bogus inclusion of algapi.h which should only be used by algorithm/driver implementors and not crypto users. Instead linux/crypto.h is added which is necessary because mac802154 also uses blkcipher in addition to aead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Acked-by: David S.
