2021-11-16net: ieee802154: handle iftypes as u32Alexander Aring1-3/+4
This patch fixes an issue that an u32 netlink value is handled as a signed enum value which doesn't fit into the range of u32 netlink type. If it's handled as -1 value some BIT() evaluation ends in a shift-out-of-bounds issue. To solve the issue we set the to u32 max which is s32 "-1" value to keep backwards compatibility and let the followed enum values start counting at 0. This brings the compiler to never handle the enum as signed and a check if the value is above NL802154_IFTYPE_MAX should filter -1 out.

2016-07-08ieee802154: add netns supportAlexander Aring1-0/+5
This patch adds netns support for 802.15.4 subsystem. Most parts are copy&pasted from wireless subsystem, it has the identically userspace API.

The PAD define should be above the experimental support. We don't care about if we break userspace in experimental stuff but PAD is part of the existing UAPI.

2015-09-30nl802154: add support for security layerAlexander Aring1-0/+191
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.

2015-08-10ieee802154: add ack request default handlingAlexander Aring1-0/+4
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.

2015-05-19ieee802154: add several phy supported handlingAlexander Aring1-0/+22
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.

Enable sparse warnings about endianness, replace the remaining fields regarding network operations without explicit endianness annotations with such that are annotated, and propagate this through the entire stack. Uses of ieee802154_addr_sa are not changed yet, this patch is only concerned with all other fields (such as address filters, operation parameters and the likes).

2014-03-14ieee802154: rename struct ieee802154_addr to *_saPhoebe Buckheister1-3/+3
The struct as currently defined uses host byte order for some fields, and most big endian/EUI display byte order for other fields. Inside the stack, endianness should ideally match network byte order where possible to minimize the number of byteswaps done in critical paths, but this patch does not address this; it is only preparatory.
