| | | | | | | | | | | | | | | | | | | | In case of error, the functions crypto_alloc_aead() and crypto_alloc_blkcipher() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

| | | | | | | | | | | | | | | | | | Currently if ieee802154_if_add failed, we don't unregister the wpan phy which was registered before.

* | cfg802154: pass name_assign_type to rdev_add_virtual_intf()Varka Bhadram2015-04-304-7/+13
|/ | | | | | | | | | | | | | | This code is based on commit 6bab2e19c5ffd ("cfg80211: pass name_assign_type to rdev_add_virtual_intf()") This will expose in sysfs whether the ifname of a IEEE-802.15.4 device is set by userspace or generated by the kernel. We are using two types of name_assign_types o NET_NAME_ENUM: Default interface name provided by kernel o NET_NAME_USER: Interface name provided by user.

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.

* mac802154: add interframe spacing time handlingAlexander Aring2014-11-135-4/+53
| | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | This patch adds support for setting short address via nl802154 framework. Also added a comment because a 0xffff seems to be valid address that we don't have a short address. This is a valid setting but we need more checks in upper layers to don't allow this address as source address. Also the current netlink interface doesn't allow to set the short_addr to 0xffff.

The pan_id 0xffff as source pan is invalid. I am not sure now about this setting but for the current netlink interface this is an invalid setting, so we do the same now.
