* drivers: Introduce device lookup variants by nameSuzuki K Poulose2019-07-301-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a helper to match the device name for device lookup. Also reuse this generic exported helper for the existing bus_find_device_by_name(). and add similar variants for driver/class.

* ieee802154: add netns supportAlexander Aring2016-07-081-1/+69
| | | | | | | | | | | This patch adds netns support for 802.15.4 subsystem. Most parts are copy&pasted from wireless subsystem, it has the identically userspace API.

* nl802154: add support for security layerAlexander Aring2015-09-301-0/+12
| | | | | | | | | | | | | This patch adds support for accessing mac802154 llsec implementation over nl802154. I added for a new Kconfig entry to provide this functionality CONFIG_IEEE802154_NL802154_EXPERIMENTAL. This interface is still in development. It provides to change security parameters and add/del/dump entries of security tables. Later we can add also a get to get an entry by unique identifier.

* mac802154: remove pib lockAlexander Aring2015-05-231-2/+0
| | | | | | | | | | This patch removes the pib lock which is now replaced by rtnl lock. The new interface already use the rtnl lock only. Nevertheless this patch will fix issues while using new and old interface at the same time.

* ieee802154: change wpan-phy name to phyAlexander Aring2015-03-141-1/+4
| | | | | | | | | | | | Currently the wpan_phy under /sys/class/ieee802154/ is named as "wpan-phy#", this patch will change the name to phy. This will introduce the same naming convention like wireless. Note: wpan-tools users will not type "wpan-phy#" anymore, just a simple "phy#" is enough.

* ieee802154: fix netns settingsNicolas Dichtel2015-02-141-0/+1
| | | | | | | | | | | | | | 6LoWPAN currently doesn't supports x-netns and works only in init_net. With this patch, we ensure that: - the wpan interface cannot be moved to another netns; - the 6lowpan interface cannot be moved to another netns; - the wpan interface is in the same netns than the 6lowpan interface; - the 6lowpan interface is in init_net.

| | | | | | | | | | This patch reworks the wpan_phy index incrementation. It's now similar like wireless wiphy index incrementation. We move the wpan_phy index attribute inside of cfg802154_registered_device and use atomic operations instead locking mechanism via wpan_phy_mutex.
