mac802154: Handle association requests from peers

2023-11-20T10:43:03+00:00

Coordinators may have to handle association requests from peers which want to join the PAN. The logic involves: - Acknowledging the request (done by hardware) - If requested, a random short address that is free on this PAN should be chosen for the device. - Sending an association response with the short address allocated for the peer and expecting it to be ack'ed. If anything fails during this procedure, the peer is considered not associated.

ieee802154: Add support for user disassociation requests

2023-11-20T10:42:47+00:00

A device may decide at some point to disassociate from a PAN, let's introduce a netlink command for this purpose. Signed-off-by: Miquel Raynal Acked-by: Stefan Schmidt Acked-by: Alexander Aring Link: https://lore.kernel.org/linux-wpan/20230927181214.129346-6-miquel.raynal@bootlin.com

mac802154: Handle associating

2023-11-20T10:42:39+00:00

Joining a PAN officially goes by associating with a coordinator. This coordinator may have been discovered thanks to the beacons it sent in the past. Add support to the MAC layer for these associations, which require: - Sending an association request - Receiving an association response The association response contains the association status, eventually a reason if the association was unsuccessful, and finally a short address that we should use for intra-PAN communication from now on, if we required one (which is the default, and not yet configurable).

ieee802154: Add support for user association requests

2023-11-20T10:42:24+00:00

Users may decide to associate with a peer, which becomes our parent coordinator. Let's add the necessary netlink support for this.

mac802154: Handle received BEACON_REQ

2023-03-23T20:51:30+00:00

When performing an active scan, devices emit BEACON_REQ which must be answered by other PANs receiving the request, unless they are already passively sending beacons. Answering a beacon request becomes a duty when the user tells us to send beacons and the request provides an interval of 15.

Active scan support is based on the current passive scan support, cheered up with beacon requests sent after every channel change.

mac802154: Handle basic beaconing

2023-01-28T12:55:10+00:00

Implement the core hooks in order to provide the softMAC layer support for sending beacons. Coordinators may be requested to send beacons in a beacon enabled PAN in order for the other devices around to self discover the available PANs automatically. Changing the channels is prohibited while a beacon operation is ongoing. The implementation uses a workqueue triggered at a certain interval depending on the symbol duration for the current channel and the interval order provided. Sending beacons in response to a BEACON_REQ frame (ie. answering active scans) is not yet supported. This initial patchset has no security support (llsec).

Stefan Schmidt says: ==================== == One of the biggest cycles for ieee802154 in a long time. We are landing the first pieces of a big enhancements in managing PAN's. We might have another pull request ready for this cycle later on, but I want to get this one out first. Miquel Raynal added support for sending frames synchronously as a dependency to handle MLME commands. Also introducing more filtering levels to match with the needs of a device when scanning or operating as a pan coordinator. To support development and testing the hwsim driver for ieee802154 was also enhanced for the new filtering levels and to update the PIB attributes. Alexander Aring fixed quite a few bugs spotted during reviewing changes. He also added support for TRAC in the atusb driver to have better failure handling if the firmware provides the needed information. Jilin Yuan fixed a comment with a repeated word in it. ================== Signed-off-by: David S. Miller

ieee802154: hwsim: Implement address filtering

2022-10-12T10:57:12+00:00

We have access to the address filters being theoretically applied, we also have access to the actual filtering level applied, so let's add a proper frame validation sequence in hwsim.
